Subject: [PATCH 0001/6423] UAS: Re-add workqueue items if submission fails.

If the original submission (or allocation) of the URBs for a SCSI
command fails, the UAS driver sticks the command structure in a
workqueue and schedules uas_do_work() to run.  That function removes the
entire queue before walking across it and attempting to resubmit.

Unfortunately, if the second submission fails, we will leak memory
(because an allocated URB was not submitted) and possibly leave the SCSI
command partially enqueued on some of the stream rings.  Fix this by
checking whether the second submission failed and re-queueing the
command to the UAS workqueue and scheduling it.

Subject: [PATCH 0002/6423] UAS: Use unique tags on non-streams devices.

UAS can work with either USB 3.0 devices that support bulk streams, or
USB 2.0 devices that do not support bulk streams.  When we're working
with a non-streams device, we need to be able to uniquely identify a
SCSI command with a tag in the IU.  Devices will barf and abort all
queued commands if they find a duplicate tag.

uas_queuecommand_lck() sets cmdinfo->stream to zero if the device
doesn't support streams, which is later passed into uas_alloc_cmd_urb()
as the variable stream.  This means the UAS driver was setting the tag
in all commands to zero for non-stream devices.  So the UAS driver won't
currently work with USB 2.0 devices.

Use the SCSI command tag instead of the stream ID for the command IU
tag.  We have to add one to the SCSI command tag because SCSI tags are
zero-based, but stream IDs are one-based, and the command tag must match
the stream ID that we're queueing the data IUs for.  Untagged SCSI
commands use stream ID 1.

Subject: [PATCH 0004/6423] usb/uas: use unique tags for all LUNs

I observed that on a device with multiple LUNs UAS was re-using the same
tag number for requests which were issued at the same time to both LUNs.
This patch uses scsi_init_shared_tag_map() to use unique tags for all
LUNs. With this patch I haven't seen the same tag number during the init
sequence anymore. Tag 1 is used for devices which do not adverise
command queueing.
This patch initilizes the queue before adding the scsi host like the
other two user in tree.

Subject: [PATCH 0005/6423] usb/uas: use scsi_host_find_tag() to find command
 from a tag

In "usb/uas: use unique tags for all LUNs" we make sure to create unique
tags across all LUNs. This patch uses scsi_host_find_tag() to obtain the
correct command which is associated with the tag.
The following changes are required:
- don't use sdev->current_cmnd anymore
  Since we can have devices which don't support command queueing we must
  ensure that we can tell the two commands apart. Even if a device
  supports comand queuing we send the INQUIRY command "untagged" for
  LUN1 while we can send a tagged command to LUN0 at the same time.
  devinfo->cmnd is used for stashing the one "untagged" command.
- tag number is altered. If stream support is used then the tag number
  must match the stream number. Therefore we can't use tag 0 and must
  start at tag 1.
  In case we have untagged commands (at least the first command) we must
  be able to distinguish between command tag 0 (which becomes 1) and
  untagged command (which becomes curently also 1).
  The following tag numbers are used:
  0: never
  1: for untagged commands (devinfo->cmnd)
  2+: tagged commands.

Subject: [PATCH 0006/6423] usb/uas: one only one status URB/host on
 stream-less connection

The status/sense URB is allocated on per-command basis. A read/write
looks the following way on a stream-less connection:

- send cmd tag X, queue status
- receive status, oh it is a read for tag X. queue status & read
- receive read
- receive status, oh I'm done for tag X. Cool call complete and free
  status urb.

This block repeats itself 1:1 for further commands and looks great so
far. Lets take a look now what happens if we do allow multiple commands:

- send cmd tag X, queue statusX (belongs to the command with the X tag)
- send cmd tag Y, queue statusY (belongs to the command with the Y tag)
- receive statusX, oh it is a read for tag X. queue statusX & a read
- receive read
- receive statusY, oh I'm done for tag X. Cool call complete and free statusY.
- receive statusX, oh it is a read for tag Y. queue statusY & before we
  queue the read the the following message can be observed:
  |sd 0:0:0:0: [sda] sense urb submission failure
  followed by a second attempt with the same result.

In order to address this problem we will use only one status URB for
each scsi host in case we don't have stream support (as suggested by
Matthew). This URB is requeued until the device removed. Nothing changes
on stream based endpoints.

Subject: [PATCH 0007/6423] ath6kl: Use cfg80211_roamed_bss() to report roaming
 event

This is to avoid the scenario where the bss entry of the AP got
expired when reporting roaming event to current AP. As the bss
entry for the current bss is available in driver, pass this bss
to cfg80211. This fixes WARNING: at net/wireless/sme.c:586.

This patch depends on the following patch in cfg80211
"cfg80211: Fix race in bss timeout".

Subject: [PATCH 0009/6423] ath6kl: Avoid taking struct as argument in
 ath6kl_wmi_set_ip_cmd

In this way, caller is free to pass only the value of IP addr
to configure.

In addition to this,
  * 'ips' variable data type in struct wmi_set_ip_cmd is changed
     from __le32 to __be32 in order to match network byte order.
  *  ipv4_is_multicast() is used to validate multicast ip addr.
  *  New argument if_idx is added to supply correct vif index
     to ath6kl_wmi_cmd_send().

This will be used in the next patch.

Subject: [PATCH 0010/6423] ath6kl: Send own IP addr to the firmware during WOW
 suspend

Firmware ARP module requires own IP addr in order to respond
to the outside world when the target is in WOW suspend state.

At present, firmware ARP module has capability to hold 2 IP addr.
So, WOW mode will be disabled if the total IP addr configured in
net_dev for our device is greater than firmware limit (MAX_IP_ADDRS)
which is 2 at this moment.

Subject: [PATCH 0011/6423] ath6kl: handle firmware names more dynamically

Currently ath6kl has just hardcoded paths to each firmware file. Change
this more dynamic by separating the the directory and file name from each
other. That way it's easier to dynamically create full paths to firmware and
code looks better. And now it's possible to remove a function needed by
devicetree code.

While at it add a structure inside struct ath6kl_hw to contain all
firmware names. I deliberately omitted board file support as
those will be handled later.

This is needed for firmware API 3.

From 65a8b4cc511b68712799e91137324f2abece7d3e Mon Sep 17 00:00:00 2001
From: Kalle Valo <kvalo@qca.qualcomm.com>
Date: Fri, 16 Dec 2011 20:53:41 +0200
Subject: [PATCH 0012/6423] ath6kl: add support for FW API 3

As firmware starting from 3.2.0.12 has some API changes and doesn't work
with older versions of ath6kl we need to bump up the API version. This
way we don't break anything.

Also store which version of API is used and print that during boot:

ath6kl: ar6003 hw 2.1.1 sdio fw 3.2.0.13 api 3

Subject: [PATCH 0013/6423] ath6kl: Fix panic when setting a channel

cfg80211 could pass a NULL net_device to the driver via the
set_channel() callback, when it receives a request to set the
device's channel. Not handling this case properly results in this panic:

Subject: [PATCH 0016/6423] ath6kl: Support for TCP checksum offload to
 firmware

The change enables offloading TCP checksum calculation to firmware.
There are still some issues with the checksum offload so better to
disable it by default until the issues are resolved.

To enable TCP checksum offload for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx on
ethtool -K <interface> rx on

To disable TCP checksum offload, for tx and rx paths, use
the ethtool as follows:
ethtool -K <interface> tx off
ethtool -K <interface> rx off

Subject: [PATCH 0020/6423] ath6kl: send TCMD response through testmode events

ath6kl no longer knows what it is transmitting through
cfg80211_testmode, and simply passes opaque buffers between userspace
and the firmware. Leave the CONT_RX enum for backwards compatibility.

kvalo: change ATH6KL_TM_CMD_RX_REPORT to return -EOPNOTSUPP

Subject: [PATCH 0021/6423] HWPOISON: Clean up memory_failure() vs.
 __memory_failure()

There is only one caller of memory_failure(), all other users call
__memory_failure() and pass in the flags argument explicitly. The
lone user of memory_failure() will soon need to pass flags too.

Add flags argument to the callsite in mce.c. Delete the old memory_failure()
function, and then rename __memory_failure() without the leading "__".

Provide clearer message when action optional memory errors are ignored.

Subject: [PATCH 0022/6423] HWPOISON: Add code to handle "action required"
 errors.

Add new flag bit "MF_ACTION_REQUIRED" to be used by machine check
code to force a signal with si_code = BUS_MCEERR_AR in the case
where the error occurs in processor execution context. Pass the
flags argument along call chain:
	memory_failure()
	  hwpoison_user_mappings()
	    kill_procs()
	      kill_proc()

Drop the "_ao" suffix from kill_procs_ao() and kill_proc_ao() since
they can now handle "action required" as well as "action optional" errors.

Subject: [PATCH 0023/6423] x86/mce: Create helper function to save addr/misc
 when needed

The MCI_STATUS_MISCV and MCI_STATUS_ADDRV bits in the bank status
registers define whether the MISC and ADDR registers respectively
contain valid data - provide a helper function to check these bits
and read the registers when needed.

In addition, processors that support software error recovery (as
indicated by the MCG_SER_P bit in the MCG_CAP register) may include
some undefined bits in the ADDR register - mask these out.

 in MCE handler

Machine checks on Intel cpus interrupt execution on all cpus, regardless
of interrupt masking.  We have a need to save some data about the cause
of the machine check (physical address) in the machine check handler that
can be retrieved later to attempt recovery in a more flexible execution
state.

Subject: [PATCH 0025/6423] x86/mce: Handle "action required" errors

All non-urgent actions (reporting low severity errors and handling
"action-optional" errors) are now handled by a work queue. This
means that TIF_MCE_NOTIFY can be used to block execution for a
thread experiencing an "action-required" fault until we get all
cpus out of the machine check handler (and the thread that hit
the fault into mce_notify_process().

We use the new mce_{save,find,clear}_info() API to get information
from do_machine_check() to mce_notify_process(), and then use the
newly improved memory_failure(..., MF_ACTION_REQUIRED) to handle
the error (possibly signalling the process).

Update some comments to make the new code flows clearer.

Recognise this, and pass MCE_AR_SEVERITY code back to do_machine_check() if
we have the action handler configured (CONFIG_MEMORY_FAILURE=y)

[  421.739719] iwlwifi 0000:01:00.0: iwl_sta_ucode_activate Added STA id 148 addr 00:00:00:00:00:00 to uCode

not sure how it happen, but adding the sanity check to prevent memory
corruption

Subject: [PATCH 0033/6423] iwlwifi: update testmode command of direct register
 access

In order to make sure the testcommand function of direct register
access can be performed even NIC is asleep, replace corresponding
handler iwl_read32 and iwl_write32 by using iwl_direct_read32 and
iwl_direct_write32.

Subject: [PATCH 0040/6423] ath6kl: Implement ndo_set_rx_mode()

There are maximum of seven multicast filter are supported
by hw. When the requested number of filters exceeds the
maximum supported one, multicast filtering is completely
disabled, the requested filters will be configured in
firmware and the only multicast frames that host is interested
in will be passed to host for further processing otherwise.

Otherwise if (ielen <= ATH6KL_MAX_IE) is dead code. It looks safe to
change the type of ielen from u8 to size_t instead of removing this
if check, this ielen can have the length of more than one ies in future.

Currently this race is handled but in a messy way an atomic

in every iteration. Remove this logic and use a mutex
to make sure irq is not disabled when irq handling is in
progress.

Subject: [PATCH 0046/6423] sfc: Remove unnecessary inclusion of <asm/io.h>,
 prompted by checkpatch

Fix the warning:

WARNING: Use #include <linux/io.h> instead of <asm/io.h>

There is no need for selftest.c to include the file at all.

Subject: [PATCH 0049/6423] sfc: Set default parallelism to per-core by default

The previous default of per-package can be more CPU-efficient, but
users generally seem to prefer per-core.  It should also allow
accelerated RFS to direct packets more precisely, if IRQ affinity
is properly spread out.

Subject: [PATCH 0053/6423] ath6kl: Fix listen interval handling

This patch addresses a few problems with the commit:

"ath6kl: Implement support for listen interval from userspace"

* The debugfs file required for reading/writing the listen interval
  wasn't created. Fix this.

* The interface index was being hardcoded to zero. Fix this.

* Two separate parameters, "listen_interval_time and listen_interval_beacons"
  were being used. This fails to work as expected because the FW assigns
  higher precedence to "listen_interval_beacons" and "listen_interval_time"
  ends up being never used at all.

  To handle this, fix the host driver to exclusively use listen interval
  based on units of beacon intervals.

To set the listen interval, a user would now do something like this:

echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval

kvalo: fix two checkpatch warnings

Subject: [PATCH 0055/6423] pci: Introduce __pci_reset_function_locked to be
 used when holding device_lock.

The use case of this is when a driver wants to call FLR when a device
is attached to it using the SysFS "bind" or "unbind" functionality.

The call chain when a user does "bind" looks as so:

 echo "0000:01.07.0" > /sys/bus/pci/drivers/XXXX/bind

and ends up calling:
  driver_bind:
    device_lock(dev);  <=== TAKES LOCK
    XXXX_probe:
         .. pci_enable_device()
         ...__pci_reset_function(), which calls
                 pci_dev_reset(dev, 0):
                        if (!0) {
                                device_lock(dev) <==== DEADLOCK

The __pci_reset_function_locked function allows the the drivers
'probe' function to call the "pci_reset_function" while still holding
the driver mutex lock.

Subject: [PATCH 0056/6423] xen/pciback: Support pci_reset_function, aka FLR or
 D3 support.

We use the __pci_reset_function_locked to perform the action.
Also on attaching ("bind") and detaching ("unbind") we save and
restore the configuration states. When the device is disconnected
from a guest we use the "pci_reset_function" to also reset the
device before being passed to another guest.

Subject: [PATCH 0059/6423] crypto: twofish-x86_64-3way - blacklist pentium4
 and atom

Performance of twofish-x86_64-3way on Intel Pentium 4 and Atom is lower than
of twofish-x86_64 module. So blacklist these CPUs.

Subject: [PATCH 0060/6423] crypto: blowfish-x86_64 - blacklist Pentium 4

Implementation in blowfish-x86_64 uses 64bit rotations which are slow on P4,
making blowfish-x86_64 slower than generic C implementation. Therefore
blacklist P4.

Subject: [PATCH 0061/6423] crypto: serpent-sse2 - change transpose_4x4 to only
 use integer instructions

Matrix transpose macro in serpent-sse2 uses mix of SSE2 integer and SSE floating
point instructions, which might cause performance penality on some CPUs.

This patch replaces transpose_4x4 macro with version that uses only SSE2
integer instructions.

Subject: [PATCH 0063/6423] crypto: Add CRYPTO_ALG_KERN_DRIVER_ONLY flag

The added CRYPTO_ALG_KERN_DRIVER_ONLY indicates whether a cipher
is only available via a kernel driver. If the cipher implementation
might be available by using an instruction set or by porting the
kernel code, then it must not be set.

  host delivers the buffered frame from the APSD power save queue.
  Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
  in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
  queue are dropped.
* When the host queues the first frame to the APSD queue or removes the
  last frame from the APSD queue, it is indicated to the firmware using
  WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.

kvalo: fix buggy handling of sks queues, made it more obvious
the user priority when wmm is disabled, remove unneed else block and
combined some variable declarations

Subject: [PATCH 0068/6423] ath6kl: Remove useless initialization in
 ath6kl_read_fwlogs()

ath6kl_read_fwlogs() assigns the value zero to the variable 'ret'
at the time of declaration. Later, return value of ath6kl_diag_read32()
repalces the init value. Hence removing useless zero assignment.

Subject: [PATCH 0069/6423] crypto: sha512 - use standard ror64()

Use standard ror64() instead of hand-written.
There is no standard ror64, so create it.

The difference is shift value being "unsigned int" instead of uint64_t
(for which there is no reason). gcc starts to emit native ROR instructions
which it doesn't do for some reason currently. This should make the code
faster.

Patch survives in-tree crypto test and ping flood with hmac(sha512) on.

Subject: [PATCH 0070/6423] firewire: move fw_device reference counting from
 drivers to core

fw_unit device drivers invariably need to talk to the fw_unit's parent
(an fw_device) and grandparent (an fw_card).  firewire-core already
maintains an fw_card reference for the entire lifetime of an fw_device.
Likewise, let firewire-core maintain an fw_device reference for the
entire lifetime of an fw_unit so that fw_unit drivers don't have to.

Subject: [PATCH 0074/6423] drm/i915: Only look for matching clocks for LVDS
 downclock

This patch enforces that the downclock clock source is the same as the preferred
clock source for LVDS. This fixes a bug where the driver chooses a downclock
clock source with a different P than the preferred mode clock source. This
happened even if the preferred clock source implemented an acceptable rate for
the downclock. The result of this bug is that downclock is disabled.

Subject: [PATCH 0075/6423] drm/i915: there is no pipe CxSR on ironlake

After checking the specs and discussing with Jesse, turns out CxSR is not
available on Ironlake and gen5, and its advertisement on the device
description is misleading.

Staring at an error state such as:

    Display B: Invalid tiling
fence[0] = 05001001
    valid, x-tiled, pitch: 512, start: 0x05000000, size: 1048576

  STRIDE: 00001400
  SIZE: 03ff04ff
  POS: 00000000

Suggests that we did not clear the DSPBCNTR prior to unpinning the
framebuffer and reusing the GTT space. Impossible! Unless our DPMS
bookkeeping ran afoul again...

In the meantime add an assertion that the plane is decoupled from the
framebuffer prior to release.

There is an error in i915_read_blc_pwm_ctl, where the register values
are not being copied correctly.  BLC_PWM_CTL and BLC_PWM_CTL2 are
getting mixed up.  This patch fixes that so that saveBLC_PWM_CTL2 and
not saveBLC_PWM_CTL is copied to the BLC_PWM_CTL2 register.

Subject: [PATCH 0088/6423] drm/i915: Use kcalloc instead of kzalloc to
 allocate array

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107

Subject: [PATCH 0089/6423] drm/i915: kill i915_mem.c

Some decent history digging indicates that this was to be used for the
GLX_MESA_allocate_memory extension but never actually implemented for
any released i915 userspace code.

So just rip it out.

v2: Fixup the Makefile.

LLC is not SNB/IVB-specific, so we should check for it in a more generic
way.

Commit c8f44affb7 ("net: introduce and use netdev_features_t for
device features sets") added netdev_features_t to ndo_set_features.
Change ath6kl to use the new type.

This fixes a warning:

Subject: [PATCH 0093/6423] ath6kl: fix uninitialized warning in
 ath6kl_process_uapsdq()

Before I commited patch c1762a3fe ("ath6kl: Add support for uAPSD") I
did a minor change how up variable is initialised in
ath6kl_process_uapsdq(). But I was sloppy and caused this compiler
warning:

txrx.c:88:5: warning: 'up' may be used uninitialized in this function

Revert my change to fix the warning.

Subject: [PATCH 0097/6423] ath6kl: add ATH6KL_CONF_UART_DEBUG

Add ATH6KL_CONF_UART_DEBUG which is set whenever uart_debug module
parameter is enabled. This way we can keep the uart_debug parameter
static when core.c file is introduced.

Subject: [PATCH 0098/6423] ath6kl: create core.c

Currently core functions are spread between various files, group all
the functions into file and rename the functions to follow the style
used elsewhere in the driver. This will make it easier to a separate core
module.

Also fix a bug where wiphy is freed too early.

Subject: [PATCH 0099/6423] ath6kl: get rid of AR_DBG_LVL_CHECK()

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to
ath6kl_core.ko.

In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ
as I removed the AR_DBG_LVL_CHECK() check before calling the function.

That way it's possible to not export debug_mask outside the upcoming

following patch.

Now ath6kl is ready for splitting core code to ath6kl_core.ko module.
This also makes it possible to link both sdio and usb code to kernel
at the same time, which earlier failed miserably.

From 241b128b6b69ad41fc6f12cba45a3c3e64bce673 Mon Sep 17 00:00:00 2001
From: Kalle Valo <kvalo@qca.qualcomm.com>
Date: Tue, 17 Jan 2012 20:09:45 +0200
Subject: [PATCH 0102/6423] ath6kl: add back beginnings of USB support

John Linville had to revert the part of USB support which was already
in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert
USB support"). Now that I fixed the build problems properly by adding
ath6kl_core.ko kernel module it's possible to add back the
(incomplete) USB support. This patch is a revert of John's patch and
adds back the USB code which as already in ath6kl, only difference
being minor changes in Makefile and adapting usb.c to new core
function names.

Note that USB support in ath6kl is not complete yet. This code only
makes it possible to boot firmware but as HTC layer does not yet
support USB it's not possible to send any WMI commands nor data
packets to the firmware. That will be added soon.

Subject: [PATCH 0103/6423] KEYS: Allow special keyrings to be cleared

The kernel contains some special internal keyrings, for instance the DNS
resolver keyring :

2a93faf1 I-----     1 perm 1f030000     0     0 keyring   .dns_resolver: empty

It would occasionally be useful to allow the contents of such keyrings to be
flushed by root (cache invalidation).

Allow a flag to be set on a keyring to mark that someone possessing the
sysadmin capability can clear the keyring, even without normal write access to
the keyring.

Set this flag on the special keyrings created by the DNS resolver, the NFS
identity mapper and the CIFS identity mapper.

Subject: [PATCH 0104/6423] ARM: 7215/1: mmc: mmci: Increase max_segs from 16
 to 128

A significant increase (10-20%) in performance throughput for
USB mass storage is the reason for incrementing the value.
By some reason the USB driver allocates buffers which requires
a scattergather list to contain a lot more than 16 elements to
get optimal performance. This change sets the maximum elements
to 128.

Tests with large reads and large writes (100 MiB) show that the
throughput increase is significant for write (10% for this test)
but not for read. Tests are run on a Linux host with ext4 FS on
the gadget mass storage device. The sg-len still exceeds 16 for
the read tests but the performance gain is low or nothing.

The patch "mmc: core: move ->request() call from atomic context",
is the reason to why this change is possible. This simplifies the
error handling code execution path quite a lot and potentially also
fixes some error handling hang problems.

Subject: [PATCH 0107/6423] ARM: 7218/1: mmc: mmci: Provide option to configure
 bus signal direction

The ST Micro variant supports bus signal direction indication. A new
member in the variant struct is added for this.

Moreover the actual signal direction configuration is board specific,
thus the amba mmci platform data is extended with a new member to be
able provide mmci with these specific board configurations.

This patch is based upon a patch from Sebastian Rasmussen.

Subject: [PATCH 0108/6423] ARM: 7219/1: mmc: mmci: Change vdd_handler to a
 generic ios_handler

The purpose of the vdd_handler does not make sense. We remove it
and use a generic approach instead. A new ios_handler is added, the
purpose of which e.g. can be to control GPIO pins to a levelshifter.

Previously the vdd_handler was also used for making additional
changes to the power register bits. This option is superfluous and is
therefore removed.

Adaptaptions from the old vdd_handler to the new ios_handler is done for
mach-ux500 board, which was the only one using the vdd_handler.

This patch is based upon a patch from Sebastian Rasmussen.

Subject: [PATCH 0110/6423] ARM: 7223/1: mmc: mmci: Fixup use of runtime PM and
 use autosuspend

Added use of runtime PM autosuspend feature, with a fixed
timeout of 50 ms. This will prevent adding a latency,
although very minor, for _every_ request.

Moreover the runtime_get_sync is now also used in set_ios and
suspend since the runtime resourses are needed here as well.

Subject: [PATCH 0114/6423] devfreq: Remove MODULE_ALIAS for exynos4 busfreq
 driver

This driver can only be built-in, it does not make sense to add modalias for
it (in addition to being incorrect, the platform modalias needs to be prefixed
with "platform:").

Subject: [PATCH 0115/6423] PM / devfreq: fixed syntax errors.

If devfreq.h was included without CONFIG_PM_DEVFREQ, there has been a
compiler error with an additional semicolon added. This patch removes
that errorneous semicolon.

Arrange the Kconfig options in rough alphabetical order, and place the

platform specific debug option rather than the 'none' option, which is
what we actually want.

Subject: [PATCH 0124/6423] regulator: s5m8767: Remove redundant MODULE_ALIAS

The MODULE_DEVICE_TABLE will setup the modalias, thus adding
a MODULE_ALIAS for an entry already in s5m8767_pmic_id is redundant.

Subject: [PATCH 0125/6423] regulators/db8500: split off shared dbx500 code

As we progress with DB5500 and future voltage domain regulators
based on very similar hardware as found in the DB8500 PRCMU,
it makes sense to split off the generic parts and introduce
some generic debug code for the DBx500 regulators. This patch
accoplish a basic abstraction of the DBx500 voltage domain
regulators.

Subject: [PATCH 0131/6423] regulator: Add devm_regulator_get()

Add a resource managed regulator_get() to simplify regulator
usage in drivers. This allows driver authors to "get and forget"
about their regulators by automatically calling regulator_put()
when the driver is detached.

[Fixed up a couple of coding style issues -- broonie]

Subject: [PATCH 0134/6423] regmap: Add support for padding between register
 and address

Some devices, especially those with high speed control interfaces, require
padding between the register and the data. Support this in the regmap API
by providing a pad_bits configuration parameter.

Only devices with integer byte counts are supported.

Subject: [PATCH 0141/6423] ASoC: Push wm8978 reset down into the I2C probe

Ensures that we get control of the CODEC earlier and don't try to probe
the card at all if register I/O isn't working.

Subject: [PATCH 0172/6423] ASoC: utils - Add support for a dummy codec driver.

This is useful to create dummy codec devices where we need to have some
DAI links without a real Codec. e.g. could be used to represent dumb FM,
MODEM, etc

This is also used by dynamic PCM for DAI links that have no codec.

Both the Snapper CL15 and EDB93xx audio drivers set the same audio
configuration in ep93xx_i2s_acquire. Remove the arguments to
ep93xx_i2s_acquire so that the audio drivers no longer need the
EP93XX_SYSCON defines exported.

Subject: [PATCH 0181/6423] ASoC: Allow drivers to specify how many bits are
 significant on a DAI

Most devices accept data in formats that don't correspond directly to
their internal format. ALSA allows us to set a msbits constraint which
tells userspace about this in case it finds it useful (for example, in
order to avoid wasting effort dithering bits that will be ignored when
raising the sample size of data) so provide a mechanism for drivers to
specify the number of bits that are actually significant on a DAI and
add the appropriate constraints along with all the others.

This is done slightly awkwardly as the constraint is specified per sample
size - we loop over every possible sample size, including ones that the
device doesn't support and including ones that have fewer bits than are
actually used, but this is harmless as the upper layers do the right thing
in these cases.

Subject: [PATCH 0183/6423] ASoC: Implement basic WM8993 interrupt support

If an interrupt is supplied then use it for thermal warning and FLL lock
notifications. When using the interrupt raise the timeout for the FLL lock
substantially to reduce the chances of spurious warnings.

McPDM internal FIFO is 24 bit wide. From the 32 bit sample
8 bit is discarded. Let application know about this
via msbits constraint.

Subject: [PATCH 0194/6423] ASoC: Make WM5100 interrupt path use regmap
 directly

This will allow us to move the interrupt allocation out of the ASoC part
of the driver and simplifies the locking by removing any reliance in the
bulk of the interrupt path on the big CODEC lock.

Subject: [PATCH 0195/6423] ASoC: Push WM5100 interrupt request into I2C probe

This is more what the device model wants us to do and will allow use by
non-audio functions before the audio part of the device has come up.

Subject: [PATCH 0199/6423] ARM: clean up idle handlers

Let's factor out the need_resched() check instead of having it duplicated
in every pm_idle implementations to avoid inconsistencies (omap2_pm_idle
is missing it already).

The forceful re-enablement of IRQs after pm_idle has returned can go.
The warning certainly doesn't trigger for existing users.

To get rid of the pm_idle calling convention oddity, let's introduce
arm_pm_idle() allowing for the local_irq_enable() to be factored out
from SOC specific implementations. The default pm_idle function becomes
a wrapper for arm_pm_idle and it takes care of enabling IRQs closer to
where they are initially disabled.

And finally move the comment explaining the reason for that turning off
of IRQs to a more proper location.

Subject: [PATCH 0219/6423] ARM: substitute arch_idle()

Now that all implementations of arch_idle() are equivalent to cpu_do_idle()
we can just use the later directly and stop including mach/system.h.

Subject: [PATCH 0220/6423] cgroup: simplify double-check locking in
 cgroup_attach_proc

To keep the complexity of the double-check locking in one place, move
the thread_group_leader check up into attach_task_by_pid().  This
allows us to use a goto instead of returning -EAGAIN.

While at it, convert a couple of returns to gotos and use rcu for the
!pid case also in order to simplify the logic.

Changes in V2:
* https://lkml.org/lkml/2011/12/22/86 (Tejun Heo)
  * Use a goto instead of returning -EAGAIN

From 819165fb34b9777f852429f2c6d6f79fbb71b9eb Mon Sep 17 00:00:00 2001
From: Jan Beulich <JBeulich@suse.com>
Date: Fri, 20 Jan 2012 16:21:41 +0000
Subject: [PATCH 0223/6423] x86: Adjust asm constraints in atomic64 wrappers

Eric pointed out overly restrictive constraints in atomic64_set(), but
there are issues throughout the file. In the cited case, %ebx and %ecx
are inputs only (don't get changed by either of the two low level
implementations). This was also the case elsewhere.

Further in many cases early-clobber indicators were missing.

Finally, the previous implementation rolled a custom alternative
instruction macro from scratch, rather than using alternative_call()
(which was introduced with the commit that the description of the
change in question actually refers to). Adjusting has the benefit of
not hiding referenced symbols from the compiler, which however requires
them to be declared not just in the exporting source file (which, as a
desirable side effect, in turn allows that exporting file to become a
real 5-line stub).

This patch does not eliminate the overly restrictive memory clobbers,
however: Doing so would occasionally make the compiler set up a second
register for accessing the memory object (to satisfy the added "m"
constraint), and it's not clear which of the two non-optimal
alternatives is better.

v2: Re-do the declaration and exporting of the internal symbols.

Date: Fri, 20 Jan 2012 16:22:04 +0000
Subject: [PATCH 0224/6423] x86: atomic64 assembly improvements

In the "xchg" implementation, %ebx and %ecx don't need to be copied
into %eax and %edx respectively (this is only necessary when desiring
to only read the stored value).

In the "add_unless" implementation, swapping the use of %ecx and %esi
for passing arguments allows %esi to become an input only (i.e.
permitting the register to be re-used to address the same object
without reload).

In "{add,sub}_return", doing the initial read64 through the passed in
%ecx decreases a register dependency.

In "inc_not_zero", a branch can be eliminated by or-ing together the
two halves of the current (64-bit) value, and code size can be further
reduced by adjusting the arithmetic slightly.

v2: Undo the folding of "xchg" and "set".

Subject: [PATCH 0225/6423] spi/s3c64xx: Log error interrupts

Although the hardware supports interrupts we're not currently using them
at all since for small transfers the overhead is greater than that for
busy waiting and for large transfers we have interrupts from the DMA.
This means that if the hardware reports an error (especially one which
might not stall transfer) we might miss it.

Take a first pass at dealing with such errors by enabling the interrupt
if we can and logging the errors if they happen. Ideally we'd report the
error via the affected transfer but since we're in master mode it's very
difficult to trigger errors at present and this code is much simpler.

Subject: [PATCH 0227/6423] spi/s3c64xx: Implement runtime PM support

Enable and disable the clocks to the SPI controller using runtime PM. This
serves the dual purpose of reducing power consumption a little and letting
the core know when the device is idle.

Subject: [PATCH 0228/6423] [media] dvb: Add a new driver for az6007

Import the az6007 driver from Terratec H7 source, as-is.

It won't compile or run, so latter patches are needed in order
to fix it.

From 6da347065062d28de035c01b298c6aebab2723fb Mon Sep 17 00:00:00 2001
From: Mauro Carvalho Chehab <mchehab@redhat.com>
Date: Thu, 21 Jul 2011 18:31:14 -0300
Subject: [PATCH 0229/6423] [media] az6007: Fix compilation troubles at az6007

Some changes are needed, in order to make az6007 compile with the
upstream tree. Most of the changes are due to the upstream drxk
module.

Even allowing its compilation, the driver is not working yet.

complete yet, as just the frontend 0 is initialized. So, more
changes will be needed, including some changes at dvb-usb core.

Subject: [PATCH 0231/6423] [media] az6007: Fix the I2C code in order to handle
 mt2063

mt2063 uses a one-byte transfer. This requires a special handling
inside the i2c code. Fix it to properly accept i2c reads. This
is needed to make the mt2063 to be detected.

Subject: [PATCH 0232/6423] [media] az6007: Comment the gate_ctl mutex

The mutex is there to protect the I2C gate. However, for some reason,
it is being called twice:

[ 2103.542796] usbcore: registered new interface driver dvb_usb_az6007
[ 2103.772392] az6007: drxk_gate_ctrl: enable
[ 2103.793900] az6007: drxk_gate_ctrl: enable

For now, let's just comment, to allow the driver to run.

Subject: [PATCH 0239/6423] [media] drxk: Don't assume a default firmware name

Move the ngene/ddbridge firmware into their drivers.

There are two reasons for that:
	1) The firmware used there didn't work for a few devices
I tested here (Terratec H5, H6 and H7);
	2) At least Terratec H7 doesn't seem to require a firmware
for it to work.

After this change, if firmware is not specified, the driver will
use a rom-based firmware (this seems to be the case for Terratec
H7, although I need to better check the USB dumps to be sure about
that).

In any case, the firmware seems to be optional, as the DRX-K driver
don't return the firmware load error.

Subject: [PATCH 0242/6423] [media] az6007: Change the az6007 read/write
 routine parameter

Use usb_device for those routines, as it allows using them on
all places. While there, rename to better express the meaning.

Subject: [PATCH 0243/6423] [media] az6007: Simplify the read/write logic

This patch introduces no functional changes. It basically defines
a macro for each different req found at the driver, and cleans the
code to use them, making easier to understand the code.

With regards to the IR handling code, although the original code
doesn't define what's the request, it is clear, from the USB logs,
that 0xc5 is for IR polling.

Subject: [PATCH 0245/6423] [media] az6007: Fix IR receive code

The code still needs to be commented, as there's a mutex
missing at the az6007_read() call. A mutex there is needed,
in order to prevent RC (or CI) calls while other operations
are in progress.

Subject: [PATCH 0248/6423] [media] az6007: Change it to use the MFE solution
 adopted at dvb-usb

This driver were written to use a previous solution for MFE at dvb-usb.
Due to the internal API changes, change the binding to work with the
new way.

Subject: [PATCH 0254/6423] [media] az6007: code cleanups and fixes

Several changes were needed to make az6007 to work, producing
the same commands as the original driver. This patch does
that.

While here, be less verbose when debug is not enabled.

Subject: [PATCH 0257/6423] [media] az6007: Be sure to use kmalloc'ed buffer
 for transfers

USB data transfers may not work if the buffer is allocated at
the stack. Be sure to use kmalloc on all places where a buffer
is needed.

Subject: [PATCH 0263/6423] drm/i915: clarify gen2 pageflip cmd

I've reviewed gen2 pageflip code to hunt down multiple prepare pageflip
issues. The only thing I've found is a slight but functionally
meaningless confusion about the length of the mi cmd.

Fix it up and add a comment about what this dword should be (according
to docs at least).

 sprites

Now that we're using the sprite WM fields, we need to take care not to
clobber them in the main update_wm functions.  While we're at it, make
sure we mask out the old sprite wm value before or'ing in the new one
when the sprite wm is updated.

Subject: [PATCH 0265/6423] drm/i915: print out which pixel format we do not
 support

Otherwise, we are left with pretty bogus message saying that the pixel
format is not supported while leaving the details to the telepatic powers.

v2: use DRM_DEBUG_KMS instead of DRM_ERROR

Subject: [PATCH 0267/6423] ASoC: Use regmap update bits operation for drivers
 using regmap

If a driver is using regmap directly ensure that we're coherent with
non-ASoC register updates by using the regmap API directly to do our
read/modify/write cycles. This will bypass the ASoC cache but drivers
using regmap directly should not be using the ASoC cache.

Subject: [PATCH 0280/6423] Input: nomadik-ske-keypad - do not assign driver's
 probe() method

Because we are using platform_device_probe() to register the driver
we do not need to assign driver's probe method. We also can mark
ske_keypad_probe(), together with ske_keypad_chip_init(), as __init
instead of __devinit.

From 409e15442fc7f7ae9d025f3ea3fdf3c60070314f Mon Sep 17 00:00:00 2001
From: Dmitry Torokhov <dmitry.torokhov@gmail.com>
Date: Sun, 22 Jan 2012 23:27:54 -0800
Subject: [PATCH 0283/6423] Input: q40kbd - convert driver to the split model

Convert the driver to standard spilt model arch-specific code registers
platform device to which driver code can bind later.

Also request IRQ immediately upon binding to the device instead of doing
this when serio port is being opened.

Subject: [PATCH 0284/6423] Input: samsung-keypad - don't synchronise with
 runtime PM put

We don't actually care if the device has been runtime suspended immediately
so we can just drop the reference without waiting for any state change to
be implemented. This may allow us to avoid some suspend/resume cycles and
is a bit more friendly to the rest of the system.

Subject: [PATCH 0289/6423] regmap: Support register patch sets

Device manufacturers frequently provide register sequences, usually not
fully documented, to be run at startup in order to provide better defaults
for devices (for example, improving performance in the light of silicon
evaluation). Support such updates by allowing drivers to register update
sets with the core. These updates will be written to the device immediately
and will also be rewritten when the cache is synced.

The assumption is that the reason for resyncing the cache will always be
that the device has been powered off. If this turns out to not be the case
then a separate operation can be provided.

Currently the implementation only allows a single set of updates to be
specified for a device, this could be extended in future.

It turned out that Nvidial (HDMI) controllers require the buffer
alignment.  Thus it's better to mark it requiring the alignment, so that
we can switch to non-aligned behavior as default in future.

Also, change the module paramter to be bint, in order to let user

Subject: [PATCH 0293/6423] [media] V4L2: Add per-device-node capabilities

If V4L2_CAP_DEVICE_CAPS is set, then the new device_caps field is filled with
the capabilities of the opened device node.

The capabilities field traditionally contains the capabilities of the physical
device, being a superset of all capabilities available at the several device
nodes. E.g., if you open /dev/video0, then if it contains VBI caps then that means
that there is a corresponding vbi node as well. And the capabilities field of
both the video and vbi nodes should contain identical caps.

However, it would be very useful to also have a capabilities field that contains
just the caps for the currently open device, hence the new CAP bit and field.

Subject: [PATCH 0296/6423] [media] it913x v1.23 use it913x_config.chip_ver to
 select firmware

As recommended by Jason at ITE, the chip version should select firmware.

However, to continue to support IT9137 firmware with different configuration
the driver will use udev->descriptor.idVendor to select the difference
between IT9135 and IT9137.

Subject: [PATCH 0297/6423] mm: cleancache: s/flush/invalidate/

Per akpm suggestions alter the use of the term flush to be
invalidate. The next patch will do this across all MM.

This change is completely cosmetic.

[v9: akpm@linux-foundation.org: change "flush" to "invalidate", part 3]

Date: Thu, 12 Jan 2012 14:03:25 -0500
Subject: [PATCH 0298/6423] mm: zcache/tmem/cleancache: s/flush/invalidate/

Complete the renaming from "flush" to "invalidate" across
both tmem frontends (cleancache and frontswap) and both tmem backends
(Xen and zcache), as required by akpm.

This change is completely cosmetic.

Subject: [PATCH 0301/6423] usb: gadget: dummy_hcd: initialize max_streams
 early

While playing with uasp I noticed that it does not work with dummy_hcd.
The problem is that uasp requires a stream capable endpoint which it is
requesting at bind time like every other gadget. dummy_hcd however
initializes the max_stream value after connect once it knows if it runs
at SS or not.
I don't think that it is might be wrong to initialize the stream
capability even at HS speed. The gadget may not use this descriptor at
HS speed so it should not cause any damage.

Subject: [PATCH 0302/6423] usb: gadget: dummy_hcd: move the transfer part into
 its own function

This patch moves the part of the code which does the bare transfer into
its function. It is a preparion for the implementation of sg support.

This patch adds sg support to dummy_hcd. It seems that uas is not able
to work with a hcd which does not support sg only based transfers.

Subject: [PATCH 0310/6423] usb: s3c-hsudc: add basic runtime_pm calls

This will enable the system to check for activity of the usb gadget
and also in a later patch to control the usbphy power-domain.
When handling the power domain there, it will be possible to remove
another reference to architecture code.

ISSUE:
If the return value of pch_udc_pcd_init() is False, the return value of
this function is unsettled.
Since pch_udc_pcd_init() always returns 0, there is not actually the issue.

CAUSE:
If pch_udc_pcd_init() is True, the variable, retval, is not set for an
appropriate value.

ISSUE:
After a USB cable is connect/disconnected, the system rarely freezes.

CAUSE:
Since the USB device controller cannot know to disconnect the USB cable, when
it is used without detecting VBUS by GPIO, the UDC driver does not notify to
USB Gadget.

Since USB Gadget cannot know to disconnect, a false setting occurred when the
USB cable is connected/disconnect repeatedly.

ISSUE:
USB Suspend interrupts occur frequently.

CAUSE:
When it is called pch_udc_reconnect() in USB Suspend, it repeats reset and
Suspend.

SOLUTION:
pch_udc_reconnect() does not enable all interrupts.  When an enumeration event
occurred the driver enables all interrupts.

Subject: [PATCH 0317/6423] usb: gadget: dummy_hcd: complete stream support

dummy_hcd provides (alloc|free)_stream() callbacks but there are not
doing anything. The transfer side also lacks matching of streams. This
patch changes this and implements stream allocation / de-allocation
support and proper urb <=> req matching.
The UDC side exposes a limit of 16 streams. DWC3, the only USB3 UDC has
no limitations in this regard except that it _needs_ to know that
streams will be used at the ep_enable time. At the host side, there is
no real limit either: XHCI can allocate any number of streams as long as
it does not run out of memory. The UAS gadget currently requests 16
streams and the UAS host side fallbacks from the requested 256 down to
16 which is fine.
From the UASP point of view (the only specified user), the number of
used streams does not really matter. The only limitation is that the
host may not use a higher stream than the gadget requested and can deal
with.

The dummy stream support has been modelled after current UAS + XHCI +
DWC3 + UASP usage which helps me testing:
- the device announces that each ep supports 16 streams (even it could
  more than that).
- the device side looks into Companion descriptor at ep_enable time and
  enables them according to it.
- the host side tries to enable the requested number of streams but the
  upper limit is the Comanion descriptor. None (zero streams) is an
  error condition, less is okay.

Subject: [PATCH 0320/6423] usb: gadget: update Michal Nazarewicz's email
 address

The m.nazarewicz@samsung.com email address is no longer valid,
so this commit replaces it with mina86@mina86.com which is
employer-agnostic and thus should be valid for foreseeable
feature.

Subject: [PATCH 0322/6423] usb: musb: drop superfluous pm_runtime calls around
 musb_shutdown

Since commit 4f9edd2d7e8d "usb: musb: Fix the crash issue during reboot"
musb_shutdown() does pm_runtime_get_sync/pm_runtime_put by itself, so
this no longer needs to be done by the caller. Also, musb_exit_debugfs()
doesn't access the device, so just drop those runtime_pm calls.

Subject: [PATCH 0325/6423] ath6kl: Make sure to delete rx aggregation timer in
 aggr_reset_state()

The timer which is used to flush rx aggregation frames needs to
be disabled when resetting the aggregation state. This is found
in code review.

The patch "ath6kl: create core.c" removes wiphy_free() from
ath6kl_cfg80211_cleanup() and misses to free wiphy in
ath6kl_sdio_remove(). This patch fixes this regression.

Subject: [PATCH 0327/6423] ath6kl: Define a structure for connection specific
 aggregation information

This patch just groups connection specific aggregation information
from struct aggr_info into a new structure (struct aggr_info_conn)
so that, in softAP mode, this can be used when each connected station
is made to have it's own aggregation state.

Subject: [PATCH 0329/6423] ath6kl: Fix bug in using tid given by addba/delba
 req events

The tid which is given in addba/delba req event is not
just tid but also muxed with the assoc id (MSB 4 bits)
which can be used to determine the corresponding connected
station in softap mode. The actual tid is LSB 4 bits. Using
the tid as it is with rx_tid[] would result in OOB or invalid
memory access in AP mode.

Subject: [PATCH 0330/6423] ath6kl: Fix bug in maintaining aggregation state in
 AP mode

Currently rx aggregation related states are maintained per
vif, but this will not properly work when operating in AP mode.
Aggregation is completely broken when more than one
11n stations are connected to AP mode vif. Fix this issue
by keeping station specific aggregation state in sta_list.

Subject: [PATCH 0331/6423] ALSA: Au88x0 - Implement subdevice volume controls

- add "PCM Playback Volume" controls for 16 playback subdevices
  This allow application to change the volume of each subdevice
  by using hardware mixer of au88x0 and default is zero gain/attenunation.

Subject: [PATCH 0332/6423] xen: use this_cpu_xxx replace percpu_xxx funcs

percpu_xxx funcs are duplicated with this_cpu_xxx funcs, so replace them
for further code clean up.

I don't know much of xen code. But, since the code is in x86 architecture,
the percpu_xxx is exactly same as this_cpu_xxx serials functions. So, the
change is safe.

Subject: [PATCH 0335/6423] ssb: SPROM: extract each core power info
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We already extract some basic info but it's incomplete, reads info
about the first core only. Used data structure doesn't allow easy
adding of more cores.
This patch adds new struct and array for storing power info. The plan
is to: switch all extractors (including the ones using NVRAM) to new
struct, switch drivers, then deprecate and finally drop old SSB fields.

From af08687b4e6d44dcdb04b519e718eb58ecb99050 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Wed, 4 Jan 2012 19:40:40 -0800
Subject: [PATCH 0347/6423] rtlwifi: Standardize RT_PRINT_DATA macro and uses

Use a single printk(KERN_DEBUG to emit the header line
to avoid any possible output interleaving.

Remove unnecessary parentheses from the calling uses.
Standardize header arg without trailing \n or colon.
Fix a few pairwiase/pairwise typos.

Subject: [PATCH 0348/6423] rtlwifi: Convert RT_TRACE macro to use
 ##__VA_ARGS__

Consolidate printks to avoid possible message interleaving
and reduce the object size.

Remove unnecessary RT_TRACE parentheses.

Miscellaneous typo and grammar fixes.
Add missing newlines to formats.
Remove duplicate KERN_DEBUG prefixes.
Coalesce formats.
Align arguments.

Subject: [PATCH 0349/6423] rtlwifi: Convert RTPRINT macro to use ##__VA_ARGS__

Consolidate printks to avoid possible message interleaving
and reduce the object size.

Remove unnecessary RTPRINT parentheses.
Coalesce formats.
Align arguments.

From 9d833ed752e91c71792dd8ebfd0f865e6a568a37 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>

Subject: [PATCH 0350/6423] rtlwifi: Convert RT_ASSERT macro to use
 ##__VA_ARGS__

Consolidate printks to avoid possible message interleaving
and reduce the object size.

Remove unnecessary RT_ASSERT parentheses.
Align arguments.
Coalesce formats.
Remove unnecessary __func__ use as the macro uses it.

Subject: [PATCH 0353/6423] rtlwifi: add CONFIG_RTLWIFI_DEBUG to remove all of
 the debug logging code

It does seem odd though to have a DBG_EMERG and not always
emit it.

What might also be useful for any embedded use is to add
CONFIG_RTLWIFI_DEBUG to conditionally remove all of the
debug logging code to reduce the largish object size.

This reduces the object size by about 1/3 (250KB)
when CONFIG_RTLWIFI_DEBUG is not set.

Subject: [PATCH 0363/6423] mac80211: minor cleanup

we would have bailed out if 'ifibss->fixed_channel'
is valid i.e. we had used 'fixed-freq' parameter in iw ibss
join command. this is with the state 'IEEE80211_IBSS_MLME_JOINED'
so no need to check for it

 allocation failures

In https://bugzilla.redhat.com/show_bug.cgi?id=771656, a kernel bug was
triggered due to a failed skb allocation that was not checked. This event
lead to an audit of all memory allocations in the complete rtlwifi family
of drivers. This patch fixes the rest.

Subject: [PATCH 0372/6423] NFC: Complete NCI deactivate in deactivate_ntf

If a target was active, complete the NCI deactivate request
only in deactivate_ntf. Otherwise, complete it at deactivate_rsp.
Deactivate_ntf represents the actual disconnection event (sent from
the NCI controller).

On carl9170, HW encryption is disabled on IBSS; the mac80211
software-based encryption is used instead. As mac80211 supports IBSS
RSN (per-STA GTK), claim its support in the carl9170 PHY.

Subject: [PATCH 0378/6423] wireless: Save original maximum regulatory
 transmission power for the calucation of the local maximum transmit power

The local maximum transmit power is the maximum power a wireless device
allowed to transmit. If Power Constraint is presented, the local maximum
power equals to the maximum allowed power defined in regulatory domain
minus power constraint.

The maximum transmit power is maximum power a wireless device capable of
transmitting, and should be used in Power Capability element (7.3.2.16
IEEE802.11 2007).

The transmit power from a wireless device should not greater than the
local maximum transmit power.

The maximum transmit power was not calculated correctly in the current
Linux wireless/mac80211 when Power Constraint is presented.

Current implementation, for retrieving priv from adapter,
uses bss_index. In multi interface environment supporting
different types, bss_index may not be unique.

Use bss_type along with bss_num to retrieve the priv.
bss_index is removed with this change.

Subject: [PATCH 0382/6423] mwifiex: derive priv from net_device instead of
 wiphy

Currently mwifiex_private pointers are derived from wiphy
structures. This will always work as long as there is only
one net_device associated with one wiphy. In scenarios where
there are multiple net_devices associated with single
wiphy, one should use net_device to derive the priv.

Subject: [PATCH 0384/6423] carl9170: remove eeprom data injection option

In the early days, this was a quite useful software
feature for testing different regdomains and chain
configurations without adding debugfs cruft into
the driver. Nowadays, the driver's phy code seems
to be stable and there's no need for it anymore.
Therefore I decided to removed altogether.

Subject: [PATCH 0390/6423] brcm80211: Convert printk(KERN_DEBUG to pr_debug

Use pr_debug to allow dynamic debugging to work.

Move an #endif to allow brcmf_dbg_hex_dump
to be outside the #if/#endif block.
Move a const char* declaration to be inside a
pr_debug so the function doesn't need a #if/#endif
block.
Don't use temporaries in debugging functions so
the code can be optimized away.

Subject: [PATCH 0394/6423] NFC: Export new attributes sensb_res and sensf_res

Export new attributes sensb_res for tech B and sensf_res
for tech F in the target info (returned as a response to
NFC_CMD_GET_TARGET).
The max size of the attributes nfcid1, sensb_res and sensf_res
is exported to user space though include/linux/nfc.

Yogesh's patch to destroy aggregation sessions when
stations are destroyed was needed, but unnecessarily
complex. Clean up this code.

It seems exceedingly unlikely that we'll ever
support swapping rate control algorithms at
runtime, so remove the unused refcounting code.

Subject: [PATCH 0399/6423] NFC: Download TI NFC init script

Download TI NFC init script during nfcwilink open operation,
after the NFC channel is registered with TI shared transport.
TI NFC init script is written in BTS format.
First, read the chip version via a special vendor specific command.
Second, we request the relevant BTS file from the user space, and
then send the BTS commands to the chip.

Subject: [PATCH 0402/6423] mac80211: in IBSS use the Auth frame to trigger STA
 reinsertion

In case of a node re-joining the cell the sta_info structure belonging to it is
first destroyed and then reinserted. In this way its internal state is reset.

The joining operation is recognised thank the Auth frame being received.

This operation is helpful in case of a node being rebooted that is joining the
ad-hoc cell again, before its purge timeout on other nodes expires.

Subject: [PATCH 0404/6423] NFC: NFC core layer should not set the target_idx

The NFC core layer should not set the target_idx.
Instead, the driver layer (e.g. NCI, PN533) should set the
target_idx, so that it will be able to identify the target
when its I/F (e.g. activate_target) is called.
This is required in order to support multiple targets.
Note that currently supported drivers (PN533 and NCI) don't
use the target_idx in their implementation.

Subject: [PATCH 0405/6423] NFC: Add NCI multiple targets support

Add the ability to select between multiple targets in NCI.
If only one target is found, it will be auto-activated.
If more than one target is found, then DISCOVER_NTF will be
generated for each target, and the host should select one by
calling DISCOVER_SELECT_CMD. Then, the target will be activated.
If the activation fails, GENERIC_ERROR_NTF is generated.

Subject: [PATCH 0412/6423] sysfs: Add s_hash to sysfs_dirent and order
 directory entries by hash

Compute a 31 bit hash of directory entries (that can fit in a signed
32bit off_t) and index the sysfs directory entries by that hash,
replacing the per directory indexes by name and by inode.  Because we
now only use a single rbtree this reduces the size of sysfs_dirent by 2
pointers.  Because we have fewer cases to deal with the code is now
simpler.

For now I use the simple hash that the dcache uses as that is easy to
use and seems simple enough.

In addition to makeing the code simpler using a hash for the file
position in readdir brings sysfs in line with other filesystems that
have non-trivial directory structures.

Subject: [PATCH 0415/6423] sysfs: Kill nlink counting.

Tracking the number of subdirectories requires an extra field that increases
the size of sysfs_dirent.  nlinks are not particularly interesting for sysfs
and the nlink counts are wrong when network namespaces are involved so stop
counting them, and always return nlink == 1.  Userspace already knows that
directories with nlink == 1 have an nlink count they can't use to count
subdirectories.

This reduces the size of sysfs_dirent by 8 bytes on 64bit platforms.

Subject: [PATCH 0417/6423] dynamic_debug: drop enabled field from struct
 _ddebug, use _DPRINTK_FLAGS_PRINT

Currently any enabled dynamic-debug flag on a pr_debug callsite will
enable printing, even if _DPRINTK_FLAGS_PRINT is off.  Checking print
flag directly allows "-p" to disable callsites without fussing with
other flags, so the following disables everything, without altering
flags user may have set:

	echo -p > $DBGFS/dynamic_debug/control

Subject: [PATCH 0418/6423] dynamic_debug: make dynamic-debug supersede DEBUG
 ccflag

If CONFIG_DYNAMIC_DEBUG is defined, honor it over DEBUG, so that
pr_debug()s are controllable, instead of always-on.  When DEBUG is
also defined, change _DPRINTK_FLAGS_DEFAULT to enable printing by
default.

Also adding _DPRINTK_FLAGS_INCL_MODNAME would be nice, but there are
numerous cases of pr_debug(NAME ": ...), which would result in double
printing of module-name.  So defer this until things settle.

Subject: [PATCH 0424/6423] dynamic_debug: describe_flags with '=[pmflt_]*'

Change describe_flags() to emit '=[pmflt_]+' for current callsite
flags, or just '=_' when they're disabled.  Having '=' in output
allows a more selective grep expression; in contrast '-' may appear
in filenames, line-ranges, and format-strings.  '=' also has better
mnemonics, saying; "the current setting is equal to <flags>".

This allows grep "=_" <dbgfs>/dynamic_debug/control to see disabled
callsites while avoiding the many occurrences of " = " seen in format
strings.

Enlarge flagsbufs to handle additional flag char, and alter
ddebug_parse_flags() to allow flags=0, so that user can turn off all
debug flags via:

  ~# echo =_ > <dbgfs>/dynamic_debug/control

Issue error when a match-spec is given multiple times in a rule.
Previous code kept last one, but was silent about it.  Docs imply only
one is allowed by saying match-specs are ANDed together, given that
module M cannot match both A and B.  Also error when last_line < 1st_line.

If _ddebug table is empty (in a CONFIG_DYNAMIC_DEBUG build this
shouldn't happen), then warn (error?) and return early.  This skips
empty table scan and parsing of setup-string, including the pr_info
call noting the parse.  By inspection, copy return-code handling from
1st ddebug_add_module() callsite to 2nd.

Subject: [PATCH 0429/6423] dynamic_debug: enlarge command/query write buffer

Current query write buffer is 256 bytes, on stack.  In comparison, the
ddebug_query boot-arg is 1024.  Allocate the buffer off heap, and
enlarge it to 4096 bytes, big enough for ~100 queries (at 40 bytes
each), and error out if not.  This makes it play nicely with large
query sets (to be added later).  The buffer should be enough for most
uses, and others should probably be split into subsets.

Subject: [PATCH 0430/6423] dynamic_debug: add trim_prefix() to provide
 source-root relative paths

trim_prefix(path) skips past the absolute source path root, and
returns the pointer to the relative path from there.  It is used to
shorten the displayed path in $DBGMT/dynamic_debug/control via
ddebug_proc_show(), and in ddebug_change() to allow relative filenames
to be used in applied queries.  For example:

  ~# echo file kernel/freezer.c +p > $DBGMT/dynamic_debug/control

  kernel/freezer.c:128 [freezer]cancel_freezing p "  clean up: %s\012"

trim_prefix(path) insures common prefix before trimming it, so
out-of-tree module paths are shown as full absolute paths.

with the query-spec keywords accepted in the control file.  Pass ""

format print, use precision to skip last char, assuming its '\n', no

Subject: [PATCH 0432/6423] dynamic_debug: process multiple debug-queries on a
 line

Insert ddebug_exec_queries() in place of ddebug_exec_query().  It
splits the query string on [;\n], and calls ddebug_exec_query() on
each.  All queries are processed independent of errors, allowing a
query to fail, for example when a module is not installed.  Empty
lines and comments are skipped.  Errors are counted, and the last
error seen (negative) or the number of callsites found (0 or positive)
is returned.  Return code checks are altered accordingly.

With this, multiple queries can be given in ddebug_query, allowing
more selective enabling of callsites.  As a side effect, a set of
commands can be batched in:

	cat cmd-file > $DBGMT/dynamic_debug/control

We dont want a ddebug_query syntax error to kill the dynamic debug
facility, so dynamic_debug_init() zeros ddebug_exec_queries()'s return
code after logging the appropriate message, so that ddebug tables are
preserved and $DBGMT/dynamic_debug/control file is created.  This
would be appropriate even without accepting multiple queries.

This patch also alters ddebug_change() to return number of callsites
matched (which typically is the same as number of callsites changed).
ddebug_exec_query() also returns the number found, or a negative value
if theres a parse error on the query.

Splitting on [;\n] prevents their use in format-specs, but selecting
callsites on punctuation is brittle anyway, meaningful and selective
substrings are more typical.

Note: splitting queries on ';' before handling trailing #comments
means that a ';' also terminates a comment, and text after the ';' is
treated as another query.  This trailing query will almost certainly
result in a parse error and thus have no effect other than the error
message.  The double corner case with unexpected results is:

     ddebug_query="func foo +p # enable foo ; +p"

The current code unnecessarily limits the number of offers we handle.
Get rid of this limitation. As part of this cleanup, also get rid of an
unused define - MAX_MSG_TYPES.

Subject: [PATCH 0434/6423] ASoC: wm8962: Optimise power consumption for IN4 DC
 measurement usage

When the hardware is configured with one or both of the IN4 inputs used
for DC measurement (with no DC blocking capacitor connected) then we can
improve power consumption slightly in idle modes by applying a register
write sequence. Provide platform data to enable this, implemented using
a regmap patch.

Subject: [PATCH 0435/6423] tty: cleanup prohibition of direct opening for
 unix98 pty master

cleanup hack added in v2.6.27-3203-g15582d3

comment from that patch:

: pty: If the administrator creates a device for a ptmx slave we should not error
:
: The open path for ptmx slaves is via the ptmx device. Opening them any
: other way is not allowed. Vegard Nossum found that previously this was not
: the case and mknod foo c 128 42; cat foo would produce nasty diagnostics

: Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

devpts_get_tty() returns non-null only for inodes on devpts, but there is no
inodes for master-devices, /dev/ptmx (/dev/pts/ptmx) is the only way to open them.
Thus we can completely forbid lookup for master-devices and eliminate that hack in
tty_init_dev() because tty_open() will get EIO from tty_driver_lookup_tty().

Subject: [PATCH 0437/6423] tty: rework pty count limiting

After adding devpts multiple-insrances sysctl kernel.pty.max limit pty count for
each devpts instance independently, while kernel.pty.nr shows total pty count.

This patch restores sysctl kernel.pty.max as global limit (4096 by default),
adds pty reseve for main devpts (mounted without "newinstance" argument),
and new sysctl to tune it: kernel.pty.reserve (1024 by default)

Also it adds devpts mount option "max=%d" to limit pty count for each devpts
instance independently. (by default NR_UNIX98_PTY_MAX == 2^20)

Thus devpts instances in containers cannot eat up all available pty even if we didn't
set any limits, while with "max" argument we can adjust limits more precisely.

Plus, now open("/dev/ptmx") return -ENOSPC in case lack of pty indexes,
this is more informative than -EIO.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As Documentation/usb/dma.txt states:

  Most drivers should *NOT* be using these primitives; they don't need
  to use this type of memory (dma-coherent), and memory returned from
  kmalloc() will work just fine.

This driver handle only very low bandwith transfers.  It is not an
obvious candidate for usb_alloc_coherent().

Using these calls only serves to complicate the code for no gain,
as has been shown by multiple bugs related to this allocation path.

Subject: [PATCH 0447/6423] USB: cdc-wdm: kill the now unnecessary
 bMaxPacketSize0 field and udev variable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We don't need bMaxPacketSize0, and keeping all these different size fields
around will only cause us to use the wrong one.

Seems the udev variable was only used for getting bMaxPacketSize0.  We
could have used it for the usb_fill_*_urb() calls, but as it wasn't
before - why start now?  Instead make the interface_to_usbdev()

Subject: [PATCH 0448/6423] USB: cdc-wdm: Avoid hanging on interface with no
 USB_CDC_DMM_TYPE
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The probe does not strictly require the USB_CDC_DMM_TYPE
descriptor, which is a good thing as it makes the driver
usable on non-conforming interfaces.  A user could e.g.
bind to it to a CDC ECM interface by using the new_id and
bind sysfs files.  But this would fail with a 0 buffer length
due to the missing descriptor.

Fix by defining a reasonable fallback size: The minimum
device receive buffer size required by the CDC WMC standard,
revision 1.1

Use dev_name() to print the proper interface name instead

 interface on MPC512x

Use INCR8 mode for system bus interface of the USB controller
on MPC512x. This is a work-around for the AHB bus lock up
problem observed on MPC512x when there is heavy simultaneous
PATA write or network (FEC) activity.

See also "12.4 The USB controller can issue transactions that lock
up the AHB bus under certain conditions" in MPC5121e (M36P) Errata.

There is a misleading difference between /proc and /sys permissions, /proc is 0555 and /sys is 0755. But
as it is impossible to create or unlink something in /sys it would be nice to have same permissions.

Subject: [PATCH 0457/6423] Driver core: driver_find() drops reference before
 returning

As part of the removal of get_driver()/put_driver(), this patch
(as1510) changes driver_find(); it now drops the reference it acquires
before returning.  The patch also adjusts all the callers of
driver_find() to remove the now unnecessary calls to put_driver().

In addition, the patch adds a warning to driver_find(): Callers must
make sure the driver they are searching for does not get unloaded
while they are using it.  This has always been the case; driver_find()
has never prevented a driver from being unregistered or unloaded.
Hence the patch will not introduce any new bugs.  The existing callers
all seem to be okay in this respect, however I don't understand the
video drivers well enough to be certain about them.

Subject: [PATCH 0458/6423] Dynamic ID addition doesn't need get_driver()

As part of the removal of get_driver()/put_driver(), this patch
(as1511) changes all the places that add dynamic IDs for drivers.
Since these additions are done by writing to the drivers' sysfs
attribute files, and the attributes are removed when the drivers are
unregistered, there is no reason to take an extra reference to the
drivers.

The one exception is the pci-stub driver, which calls pci_add_dynid()
as part of its registration.  But again, there's no reason to take an
extra reference here, because the driver can't be unloaded while it is
being registered.

As part of the removal of get_driver()/put_driver(), this patch

Subject: [PATCH 0461/6423] Eliminate get_driver() and put_driver()

Now that there are no users of get_driver() or put_driver(), this
patch (as1513) removes those routines completely.

Subject: [PATCH 0464/6423] MISC: convert drivers/misc/* to use
 module_spi_driver()

This patch converts the drivers in drivers/misc/* to use the
module_spi_driver() macro which makes the code smaller and a bit
simpler.

Subject: [PATCH 0465/6423] sysctl: remove impossible condition check

Remove checks for conditions that will never happen. If procname is NULL
the loop would already had bailed out, so there's no need to check it
again.

At the same time this also compacts the function find_in_table() by
refactoring it to be easier to read.

Subject: [PATCH 0467/6423] sysctl: Register the base sysctl table like any
 other sysctl table.

Simplify the code by treating the base sysctl table like any other
sysctl table and register it with register_sysctl_table.

To ensure this table is registered early enough to avoid problems
call sysctl_init from proc_sys_init.

Rename sysctl_net.c:sysctl_init() to net_sysctl_init() to avoid
name conflicts now that kernel/sysctl.c:sysctl_init() is no longer
static.

From 1f87f0b52b1d6581168cb80f86746bc4df918d01 Mon Sep 17 00:00:00 2001
From: "Eric W. Biederman" <ebiederm@xmission.com>
Date: Fri, 6 Jan 2012 04:07:15 -0800
Subject: [PATCH 0468/6423] sysctl: Move the implementation into
 fs/proc/proc_sysctl.c

Move the core sysctl code from kernel/sysctl.c and kernel/sysctl_check.c
into fs/proc/proc_sysctl.c.

Currently sysctl maintenance is hampered by the sysctl implementation
being split across 3 files with artificial layering between them.
Consolidate the entire sysctl implementation into 1 file so that
it is easier to see what is going on and hopefully allowing for
simpler maintenance.

For functions that are now only used in fs/proc/proc_sysctl.c remove
their declarations from sysctl.h and make them static in fs/proc/proc_sysctl.c

- * __register_sysctl_paths - register a sysctl hierarchy
- * @root: List of sysctl headers to register on
- * @namespaces: Data to compute which lists of sysctl entries are visible
- * @path: The path to the directory the sysctl table is in.
- * @table: the top-level table structure
- *
- * Register a sysctl table hierarchy. @table should be a filled in ctl_table
- * array. A completely 0 filled entry terminates the table.
- *
- * The members of the &struct ctl_table structure are used as follows:
- *
- * procname - the name of the sysctl file under /proc/sys. Set to %NULL to not
- *            enter a sysctl file
- *
- * data - a pointer to data for use by proc_handler
- *
- * maxlen - the maximum size in bytes of the data
- *
- * mode - the file permissions for the /proc/sys file, and for sysctl(2)
- *
- * child - a pointer to the child sysctl table if this entry is a directory, or
- *         %NULL.
- *
- * proc_handler - the text handler routine (described below)
- *
- * de - for internal use by the sysctl routines
- *
- * extra1, extra2 - extra pointers usable by the proc handler routines
- *
- * Leaf nodes in the sysctl tree will be represented by a single file
- * under /proc; non-leaf nodes will be represented by directories.
- *
- * sysctl(2) can automatically manage read and write requests through
- * the sysctl table.  The data and maxlen fields of the ctl_table
- * struct enable minimal validation of the values being written to be
- * performed, and the mode field allows minimal authentication.
- *
- * There must be a proc_handler routine for any terminal nodes
- * mirrored under /proc/sys (non-terminals are handled by a built-in
- * directory handler).  Several default handlers are available to
- * cover common cases -
- *
- * proc_dostring(), proc_dointvec(), proc_dointvec_jiffies(),
- * proc_dointvec_userhz_jiffies(), proc_dointvec_minmax(), 
- * proc_doulongvec_ms_jiffies_minmax(), proc_doulongvec_minmax()
- *
- * It is the handler's job to read the input buffer from user memory
- * and process it. The handler should return 0 on success.
- *
- * This routine returns %NULL on a failure to register, and a pointer
- * to the table header on success.

Subject: [PATCH 0469/6423] sysctl: Make the directories have nlink == 1

I goofed when I made sysctl directories have nlink == 0.
nlink == 0 means the directory has been deleted.
nlink == 1 meands a directory does not count subdirectories.

Use the default nlink == 1 for sysctl directories.

Subject: [PATCH 0471/6423] sysctl: Remove the unnecessary sysctl_set parent
 concept.

In sysctl_net register the two networking roots in the proper order.

In register_sysctl walk the sysctl sets in the reverse order of the
sysctl roots.

Remove parent from ctl_table_set and setup_sysctl_set as it is no
longer needed.

Subject: [PATCH 0472/6423] sysctl: Create local copies of directory names used
 in paths

Creating local copies of directory names is a good idea for
two reasons.
- The dynamic names used by callers must be copied into new
  strings by the callers today to ensure the strings do not
  change between register and unregister of the sysctl table.

- Sysctl directories have a potentially different lifetime
  than the time between register and unregister of any
  particular sysctl table.

Subject: [PATCH 0473/6423] sysctl: Add support for register sysctl tables with
 a normal cstring path.

Make __register_sysctl_table the core sysctl registration operation and
make it take a char * string as path.

Now that binary paths have been banished into the real of backwards
compatibility in kernel/binary_sysctl.c where they can be safely
ignored there is no longer a need to use struct ctl_path to represent
path names when registering ctl_tables.

Start the transition to using normal char * strings to represent
pathnames when registering sysctl tables.  Normal strings are easier
to deal with both in the internal sysctl implementation and for
programmers registering sysctl tables.

__register_sysctl_paths is turned into a backwards compatibility wrapper
that converts a ctl_path array into a normal char * string.

Subject: [PATCH 0474/6423] sysctl: Add ctl_table chains into cstring paths

For any component of table passed to __register_sysctl_paths
that actually serves as a path, add that to the cstring path
that is passed to __register_sysctl_table.

The result is that for most calls to __register_sysctl_paths
we only pass a table to __register_sysctl_table that contains
no child directories.

Split the registration of a complex ctl_table array which may have

into a series of simpler registrations that only register tables of files.

Graphically:

   register('dir', { + file-a

                     + subdir2
                       + file-d
                       + file-e })

is transformed into:
   wrapper->subheaders[0] = register('dir', {file1-a, file1-b})
   wrapper->subheaders[1] = register('dir/subdir1', {file-c})
   wrapper->subheaders[2] = register('dir/subdir2', {file-d, file-e})
   return wrapper

This guarantees that __register_sysctl_table will only see a simple
ctl_table array with all entries having (->child == NULL).

Care was taken to pass the original simple ctl_table arrays to
__register_sysctl_table whenever possible.

This change is derived from a similar patch written
by Lucrian Grijincu.

From 7c60c48f58a78195acc1f71c9a9d01958c02ab89 Mon Sep 17 00:00:00 2001
From: "Eric W. Biederman" <ebiederm@xmission.com>
Date: Sat, 21 Jan 2012 13:34:05 -0800
Subject: [PATCH 0476/6423] sysctl: Improve the sysctl sanity checks

- Stop validating subdirectories now that we only register leaf tables

- Cleanup and improve the duplicate filename check.
  * Run the duplicate filename check under the sysctl_lock to guarantee
    we never add duplicate names.
  * Reduce the duplicate filename check to nearly O(M*N) where M is the
    number of entries in tthe table we are registering and N is the
    number of entries in the directory before we got there.

- Move the duplicate filename check into it's own function and call
  it directtly from __register_sysctl_table

- Kill the config option as the sanity checks are now cheap enough
  the config option is unnecessary. The original reason for the config
  option was because we had a huge table used to verify the proc filename
  to binary sysctl mapping.  That table has now evolved into the binary_sysctl
  translation layer and is no longer part of the sysctl_check code.

- Tighten up the permission checks.  Guarnateeing that files only have read
  or write permissions.

- Removed redudant check for parents having a procname as now everything has
  a procname.

- Generalize the backtrace logic so that we print a backtrace from
  any failure of __register_sysctl_table that was not caused by
  a memmory allocation failure.  The backtrace allows us to track
  down who erroneously registered a sysctl table.

Bechmark before (CONFIG_SYSCTL_CHECK=y):
    make-dummies 0 999 -> 12s
    rmmod dummy        -> 0.08s

Bechmark before (CONFIG_SYSCTL_CHECK=n):
    make-dummies 0 999 -> 0.7s
    rmmod dummy        -> 0.06s
    make-dummies 0 99999 -> 1m13s
    rmmod dummy          -> 0.38s

Benchmark after:
    make-dummies 0 999 -> 0.65s
    rmmod dummy        -> 0.055s
    make-dummies 0 9999 -> 1m10s
    rmmod dummy         -> 0.39s

The sysctl sanity checks now impose no measurable cost.

Subject: [PATCH 0477/6423] sysctl: Remove the now unused ctl_table parent
 field.

While useful at one time for selinux and the sysctl sanity
checks those users no longer use the parent field and we can
safely remove it.

Subject: [PATCH 0478/6423] sysctl: A more obvious version of grab_header.

Instead of relying on sysct_head_next(NULL) to magically
return the right header for the root directory instead
explicitly transform NULL into the root directories header.

Subject: [PATCH 0479/6423] sysctl: Initial support for auto-unregistering
 sysctl tables.

Add nreg to ctl_table_header.  When nreg drops to 0 the ctl_table_header
will be unregistered.

Factor out drop_sysctl_table from unregister_sysctl_table, and add
the logic for decrementing nreg.

Subject: [PATCH 0483/6423] sysctl: Rewrite proc_sys_lookup introducing
 find_entry and lookup_entry.

Replace the helpers that proc_sys_lookup uses with helpers that work
in terms of an entire sysctl directory.  This is worse for sysctl_lock
hold times but it is much better for code clarity and the code cleanups
to come.

find_in_table is no longer needed so it is removed.

find_entry a general helper to find entries in a directory is added.

lookup_entry is a simple wrapper around find_entry that takes the
sysctl_lock increases the use count if an entry is found and drops
the sysctl_lock.

Subject: [PATCH 0484/6423] sysctl: Rewrite proc_sys_readdir in terms of
 first_entry and next_entry

Replace sysctl_head_next with first_entry and next_entry.  These new
iterators operate at the level of sysctl table entries and filter
out any sysctl tables that should not be shown.

Utilizing two specialized functions instead of a single function removes
conditionals for handling awkward special cases that only come up
at the beginning of iteration, making the iterators easier to read
and understand.

Subject: [PATCH 0485/6423] sysctl: Add a root pointer to ctl_table_set

Add a ctl_table_root pointer to ctl_table set so it is easy to
go from a ctl_table_set to a ctl_table_root.

Subject: [PATCH 0486/6423] sysctl: Stop requiring explicit management of
 sysctl directories

Simplify the code and the sysctl semantics by autogenerating
sysctl directories when a sysctl table is registered that needs
the directories and autodeleting the directories when there are
no more sysctl tables registered that need them.

Autogenerating directories keeps sysctl tables from depending
on each other, removing all of the arcane register/unregister
ordering constraints and makes it impossible to get the order
wrong when reigsering and unregistering sysctl tables.

Autogenerating directories yields one unique entity that dentries
can point to, retaining the current effective use of the dcache.

Add struct ctl_dir as the type of these new autogenerated
directories.

The attached_by and attached_to fields in ctl_table_header are
removed as they are no longer needed.

The child field in ctl_table is no longer needed by the core of
the sysctl code.  ctl_table.child can be removed once all of the
existing users have been updated.

Benchmark before:
    make-dummies 0 999 -> 0.7s
    rmmod dummy        -> 0.07s
    make-dummies 0 9999 -> 1m10s
    rmmod dummy         -> 0.4s

Benchmark after:
    make-dummies 0 999 -> 0.44s
    rmmod dummy        -> 0.065s
    make-dummies 0 9999 -> 1m36s
    rmmod dummy         -> 0.4s

Subject: [PATCH 0487/6423] sysctl: Add sysctl_print_dir and use it in
 get_subdir

When there are errors it is very nice to know the full sysctl path.
Add a simple function that computes the sysctl path and prints it
out.

Subject: [PATCH 0488/6423] sysctl: Replace root_list with links between
 sysctl_table_sets.

Piecing together directories by looking first in one directory
tree, than in another directory tree and finally in a third
directory tree makes it hard to verify that some directory
entries are not multiply defined and makes it hard to create
efficient implementations the sysctl filesystem.

Replace the sysctl wide list of roots with autogenerated
links from the core sysctl directory tree to the other
sysctl directory trees.

This simplifies sysctl directory reading and lookups as now
only entries in a single sysctl directory tree need to be
considered.

Benchmark before:
    make-dummies 0 999 -> 0.44s
    rmmod dummy        -> 0.065s
    make-dummies 0 9999 -> 1m36s
    rmmod dummy         -> 0.4s

Benchmark after:
    make-dummies 0 999 -> 0.63s
    rmmod dummy        -> 0.12s
    make-dummies 0 9999 -> 2m35s
    rmmod dummy         -> 18s

The slowdown is caused by the lookups used in insert_headers
and put_links to see if we need to add links or remove links.

Subject: [PATCH 0489/6423] sysctl: Modify __register_sysctl_paths to take a
 set instead of a root and an nsproxy

An nsproxy argument here has always been awkard and now the nsproxy argument
is completely unnecessary so remove it, replacing it with the set we want
the registered tables to show up in.

Subject: [PATCH 0490/6423] sysctl: Move sysctl_check_dups into insert_header

Simplify the callers of insert_header by removing explicit calls to check
for duplicates and instead have insert_header do the work.

This makes the code slightly more maintainable by enabling changes to
data structures where the insertion of new entries without duplicate
suppression is not possible.

There is not always a convenient path string where insert_header
is called so modify sysctl_check_dups to use sysctl_print_dir
when printing the full path when a duplicate is discovered.

Subject: [PATCH 0491/6423] sysctl: Make the header lists per directory.

Slightly enhance efficiency and clarity of the code by making the
header list per directory instead of per set.

Benchmark before:
    make-dummies 0 999 -> 0.63s
    rmmod dummy        -> 0.12s
    make-dummies 0 9999 -> 2m35s
    rmmod dummy         -> 18s

Benchmark after:
    make-dummies 0 999 -> 0.32s
    rmmod dummy        -> 0.12s
    make-dummies 0 9999 -> 1m17s
    rmmod dummy         -> 17s

Subject: [PATCH 0492/6423] sysctl: Index sysctl directories with rbtrees.

One of the most important jobs of sysctl is to export network stack
tunables.  Several of those tunables are per network device.  In
several instances people are running with 1000+ network devices in
there network stacks, which makes the simple per directory linked list
in sysctl a scaling bottleneck.   Replace O(N^2) sysctl insertion and
lookup times with O(NlogN) by using an rbtree to index the sysctl
directories.

Benchmark before:
    make-dummies 0 999 -> 0.32s
    rmmod dummy        -> 0.12s
    make-dummies 0 9999 -> 1m17s
    rmmod dummy         -> 17s

Benchmark after:
    make-dummies 0 999 -> 0.074s
    rmmod dummy        -> 0.070s
    make-dummies 0 9999 -> 3.4s
    rmmod dummy         -> 0.44s

Benchmark after (without dev_snmp6):
    make-dummies 0 9999 -> 0.75s
    rmmod dummy         -> 0.44s
    make-dummies 0 99999 -> 11s
    rmmod dummy          -> 4.3s

At 10,000 dummy devices the bottleneck becomes the time to add and
remove the files under /proc/sys/net/dev_snmp6.  I have commented
out the code that adds and removes files under /proc/sys/net/dev_snmp6
and taken measurments of creating and destroying 100,000 dummies to
verify the sysctl continues to scale.

Subject: [PATCH 0493/6423] sysctl: Add register_sysctl for normal sysctl users

The plan is to convert all callers of register_sysctl_table
and register_sysctl_paths to register_sysctl.  The interface
to register_sysctl is enough nicer this should make the callers
a bit more readable.  Additionally after the conversion the
230 lines of backwards compatibility can be removed.

Subject: [PATCH 0494/6423] xen/netfront: add netconsole support.

add polling interface to xen-netfront device to support netconsole

This patch also alters the spin_lock usage to use irqsave variant.
Documentation/networking/netdevices.txt states that start_xmit
can be called with interrupts disabled by netconsole and therefore using
the irqsave/restore locking in this function is looks correct.

Subject: [PATCH 0496/6423] drm/i915: Remove the MI_FLUSH_ENABLE setting.

We have always been using the wrong bit -- it's bit 12.  However, the
bit also doesn't do anything -- hardware has always accepted the
MI_FLUSH command even when it was specced not to.

Given that there is only one MI_FLUSH emitted in all of the driver
stack on gen6+ (in i965_video.c of the 2d driver, and it should be
using other code to do its flush instead), just remove the MI_FLUSH
enable instead of trying to fix it.

Subject: [PATCH 0498/6423] ARM: 7300/1: realview: fix definition of GPIO0
 interrupt on PB1176 to match TRM

Currently, -1 is used as the GPIO0 interrupt on realview PB1176 and an
AMBA device is registered with this parameter. With the pending NO_IRQ
cleanup, this will lead to a warning at boot time, since -1 is obviously
broken.

This patch updates the interrupt used for GPIO0 to match that specified
by the TRM. Unfortunately, it's not clear how to trigger this interrupt
so we trust that the documentation is correct.

Subject: [PATCH 0520/6423] OMAPDSS: FEAT: Add FIFO_MERGE feature

Add feature flag for fifo merge. OMAP2 doesn't contain fifo merge, later
OMAPs do.

dispc_enable_fifomerge() checks for the flag when called, and gives a
WARN if fifo merge is being enabled when it is not supported.

Subject: [PATCH 0521/6423] OMAPDSS: APPLY: add fifo merge support funcs

Add mechanism to set/unset the DISPC fifo-merge:

Add new fields to dss_data, fifo_merge and fifo_merge_dirty. These are
similar to the other info/dirty flags in ovl_priv_data and ovl_mgr_data,
but fifo merge is a common attribute to all managers and thus outside
the ovl_mgr_data.

The fifo-merge field is used in the dss_write_regs_common, which handles
writing the register.

dss_apply_fifo_merge() can be used to set/unset the fifo merge field in
the dss_data.

Subject: [PATCH 0522/6423] OMAPDSS: APPLY: add fifo-merge support

Add fifo-merge support. This is done mainly in four functions:
mgr_enable/disable and ovl_enable/disable. These are the functions where
overlays are taken into and out of active use.

The process to enable and disable fifo-merge is not simple. We need to
do it in steps, waiting in between for certain settings to be taken into
use, and continuing after that. The reason for this is that fifo-merge
is a common thing for all managers/overlays, and its use must be
synchronized.

As an example, when we disable an overlay, we first set the overlay as
disabled, then wait until the overlay is actually disabled in the HW,
and only after that we may re-configure the fifos, possibly taking
fifo-merge into use.

Subject: [PATCH 0523/6423] OMAPDSS: DISPC: print fifo threshold values in
 bytes

Fifo thresholds are calculated using bytes, but the debug print prints
values in buffer units. Change the prints to use bytes to be in line
with the calculations, and also to print in the same units on all OMAPs.

Subject: [PATCH 0525/6423] OMAPDSS: DISPC: Add naive threshold calc for
 fifomerge

Take fifo merge into use by implementing a rather naive fifo merge
threshold calculation: keep the low threshold always the same, but
increase the high threshold when fifo merge is used.

This should greatly increase the time between pixel data fetches from
SDRAM, as the usable fifo size is much larger. However, it probably
won't help for fifo underflows, as the low threshols is kept the same.

Subject: [PATCH 0528/6423] OMAPDSS: HDMI: change the timing match logic

Change the timing match logic, Instead of the statically mapped method
to get the corresponding timings for a given code and mode, move to a
simpler array indexed method. It  will help to scale up to add more
timings when needed.

venc driver registration on OMAP4. Since the driver never gets
probed/initialised your get a dereferenceed NULL pointer if you

Subject: [PATCH 0533/6423] regulator: Reverse the disable sequence in
 regulator_bulk_disable()

Often there is a need for disabling a set of regulators in order opposite
to the enable order. Currently the function regulator_bulk_disable() walks
list of regulators in same order as regulator_bulk_enable(). This may cause
trouble, especially for devices with mixed analogue and digital circuits.
So reverse the disabling sequence of regulator_bulk_disable().
While at it, also correct the comment.

Subject: [PATCH 0534/6423] regmap: Unexport regcache_write() and
 regcache_read()

They have no current users which is fortunate as they don't take the lock
and therefore aren't safe to use externally. We'll need to add new
operations if direct cache access is needed.

Subject: [PATCH 0540/6423] net: usb: qmi_wwan: New driver for Huawei QMI based
 WWAN devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
near standard CDC ECM interfaces in addition to the usual serial
interfaces.   The Huawei E392/E398 are examples of such devices.

These typically cannot be fully configured using AT commands
over a serial interface.  It is necessary to speak the proprietary
Qualcomm MSM Interface (QMI) protocol to the device to enable the
ethernet proxy functionality.

The devices embed the QMI protocol in CDC on the control interface,
using standard CDC commands and notifications. The do not otherwise
use CDC commands for the ethernet function.  This driver does
therefore not need access to any other aspects of the control
interface than the descriptors attached to it.

Another driver, cdc-wdm, will provide userspace access to the
QMI protocol independently of this driver.  To facilitate this,
this driver avoids binding to the control interface, and uses
only the associated data interface after parsing the common CDC
functional descriptors on the control interface.

You will want both the cdc-wdm and option drivers as companions to
this driver, to have full access to all interfaces and protocols
exported by the device.

Subject: [PATCH 0541/6423] drm/i915: Correct the bit number for the
 MI_FLUSH_ENABLE.

Older specs claimed this was bit 11, but newer specs and the actual
simulator code say it was bit 12.  Regardless, we don't use MI_FLUSH,
or try to enable it any more.

Subject: [PATCH 0548/6423] e1000e: add Receive Packet Steering (RPS) support

Enable RPS by default.  Disallow jumbo frames when both receive checksum
and receive hashing are enabled because the hardware cannot do both IP
payload checksum (enabled when receive checksum is enabled when using
packet split which is used for jumbo frames) and provide RSS hash at the
same time.

v2: added ethtool command to query flow hashing behavior per Ben Hutchings
    and changed the type of rsskey to cleanup the setting of the register
    array and avoid unnecessary casts (as pointed out by Joe Perches).
    The long error messages are not changed since there is nothing in
    the kernel ./Documentation that suggests the preferred method for
    dealing with long messages other than to never break strings; leaving
    them as-is for now.

Subject: [PATCH 0550/6423] e1000e: convert head, tail and itr_register offsets
 to __iomem pointers

The Tx/Rx head and tail registers and itr_register are always at known
addresses based on the __iomem address at which the PCI region (from BAR 0)
is mapped and known offsets within the region for each of these registers.
Store and use the full address rather than just the region offset to reduce
unnecessary address calculations.  Also, change current u8 __iomem pointers
to void __iomem pointers.

Based on a patch from Prabhakar Kushwaha <prabhakar@freescale.com>, set
appropriate default interrupt mode dependent on whether CONFIG_PCI_MSI
is enabled in the kernel configuration and if the hardware supports
MSI-X.  Set the module parameter log message accordingly.

Subject: [PATCH 0556/6423] e1000e: use default settings for Tx Inter Packet
 Gap timer

Use the default hardware values for TIPG except for 80003es2lan(*).  The
code that is removed in this patch is either unnecessarily writing the TIPG
register with the hardware default values for some devices (82571/2/3/4) or
writing the wrong value for others (ICH/PCH LOMs).  The only change in
functionality is setting the correct default TIPG for the latter devices.

(*) The correct value for 80003es2lan is already set properly in
e1000_init_hw_80003es2lan() and e1000_cfg_kmrn_{10_100|1000}_80003es2lan(),
and the unused flag FLAG_TIPG_MEDIUM_FOR_80003ESLAN is removed.

This code snippet is simply writing default values to the register which is
unnecessary since the values are programmed into the register by default.
There is a special case for 80003es2lan needing the Retransmit on Late
Collision bit set but that is also done in e1000_init_hw_80003es2lan().

Subject: [PATCH 0559/6423] drm/i915: argument to control retiring behavior

Sometimes it may be the case when we idle the gpu or wait on something
we don't actually want to process the retiring list. This patch allows
callers to choose the behavior.

Subject: [PATCH 0560/6423] drm/i915: drm/i915: Fix recursive calls to unmap

After the ILK vt-d workaround patches it became clear that we had
introduced a bug.  Chris Wilson tracked down the issue to recursive
calls to unmap. This happens because we try to optimize waiting on
requests by calling retire requests after the wait, which may drop the
last reference on an object and end up freeing the object (and then
unmap the object from the gtt).

After the last patch we can now choose to defer processing the retire
list.

Kudos to Chris Wilson for tracking this one down.

This patch fixes gem_unref_active_buffers from i-g-t. It was tested by
forcing do_idle_maps to true.

This also fixes tests/gem_linear_blits in intel-gpu-tools.

This is only relevant when using module unloading, and really only helps
get rid of a probably benign warning.

I can't remember if I sent this out already, but it's not turning up in
any of my searches.

Subject: [PATCH 0562/6423] x86-64: Fix memset() to support sizes of 4Gb and
 above

While currently there doesn't appear to be any reachable in-tree
case where such large memory blocks may be passed to memset()
(alloc_bootmem() being the primary non-reachable one, as it gets
called with suitably large sizes in FLATMEM configurations), we
have recently hit the problem a second time in our Xen kernels.

Rather than working around it a second time, prevent others from
falling into the same trap by fixing this long standing
limitation.

From 7a31f6f48bb6e37b3195fcecd69d30740f6b0036 Mon Sep 17 00:00:00 2001
From: Hiroshi DOYU <hdoyu@nvidia.com>
Date: Thu, 17 Nov 2011 07:31:31 +0200
Subject: [PATCH 0564/6423] ARM: IOMMU: Tegra30: Add iommu_ops for SMMU driver

Tegra 30 IOMMU H/W, SMMU (System Memory Management Unit). This patch
implements struct iommu_ops for SMMU for the upper IOMMU API.

This H/W module supports multiple virtual address spaces(domain x4),
and manages 2 level H/W translation pagetable.

Subject: [PATCH 0566/6423] ASoC: OMAP4: Rename the sdp4430 machine driver

The same machine driver will support other boards
with similar audio configuration (OMAP4, ABE, twl6040).
Rename the driver to have more generic name.

Subject: [PATCH 0573/6423] ASoC: omap-abe-twl6040: DAI link selection based on
 platform data

We can have machines without DMIC connected. In this case there is
no need to create amother (unusable) capture PCM on the card.
The existence of the DMIC connection can be checked via
pdata->has_dmic.
Select the correct dai_link structure for the card based on
pdata->has_dmic.

Subject: [PATCH 0578/6423] ASoC: Provide REGULATOR_SUPPLY widget type

Modern devices allow systems to enable and disable individual supplies on
the device, allowing additional power saving by switching off regulators
which power portions of the device which are not currently in use. Add a
new SND_SOC_DAPM_REGULATOR_SUPPLY widget type factoring out the code for
managing such widgets from individual drivers.

The widget name will be used as the supply name when requesting the
regulator from the regulator API.

Subject: [PATCH 0583/6423] [media] anysee: repeat failed USB control messages

Control message load increased heavily after CI/CAM support due
to dvb_ca_en50221. It looks like CI/CAM drops to non-working
state easily after error is returned to its callbacks. Due to
that, add some logic to avoid errors repeating failed messages.

Subject: [PATCH 0586/6423] regmap: Reset device debugfs when reinitialising
 the cache

Most of the data exposed via debugfs is for or from the cache so reset
all the debugfs configuration to make sure everything is up to date with
the latest configuration, especially if we're changing cache type.

Subject: [PATCH 0588/6423] ASoC: wm5100: Use pm_runtime for powerdown
 managment

Using pm_runtime to decide if the device should go into full power down
has the dual advantage of allowing easier integration with non-DAPM
reasons to power on the device (like the FLL) and allowing userspace to
control the final power down which is useful for tuning retention of
DSP firmware.

Subject: [PATCH 0589/6423] bnx2x: Support Queue Per Cos in 5771xx devices

Enable the use of up to three hardware queues for transmission. The queues
are always dequed round robin (i.e. strict priority, PFC and ETS are not
supported). This does allow the allocation of a seperate HW queue for low
volume, high priority traffic which will be serviced more promptly.

Subject: [PATCH 0590/6423] bnx2x: Removing indirect register access

In virtualized environments indirect access to the device may not be supported
(depending on the Hypervisor type). Indirect device access was used since in
some harware contexts (i.e. certain chipset and BIOS) every access the driver
makes across the pci is followed by a BIOS initiated Zero Length Read to the
same address. When accessing widebus registers this zero length read corrupts
the serialization of the read/write sequence resulting with errors. To avoid
this problem widebus registers are always accessed via the DMAE or the indirect
interface. However, the 57712x and 578xx devices intercept the zero length read
and so using the indirect interface with these devices is not necessary. Since
PDA is only supported for 57712x and 578xx the indirect access to device was
restricted to 57710 and 57711x.

BDF was obtained from kernel but since in virtualized environment
(e.g. physical device assigment in KVM) the function number may
not be the real one, the info must be obtained from the device.

Subject: [PATCH 0593/6423] bnx2x: Loaded Firmware Version Validation

In a virtualized environment it is possible for a loading driver to discover
that Firmware is already loaded to the device, and that this FW does not match
its own. This can happen for example if different Physical Functions are
Assigned to different VMs in which different driver versions are loaded. The
code in this patch ensures that only drivers with matching FW are loaded over
the device, and that in the case described above where the Firmware version
doesn't match the driver load is aborted.

Subject: [PATCH 0594/6423] bnx2x: Lock PF-common resources

Use hardware locks to protect resources common to several Physical Functions. In
a virtualized environment the RTNL lock only protects a PF's driver against
the PFs sharing it's VMs with regard to device resources. Other PFs may reside
in other VMs under other OSs, and are not subject to the lock. Such resources
which were previously protected implicitly by the RTNL lock must now be
protected explicitly with dedicated HW locks.

Subject: [PATCH 0595/6423] bnx2x: Track active PFs with bitmap

The recovery register (to which a hardware lock has been added in previous
patch) is used amongst other things to track the active PFs. The old
implementation which used a per path counter is not viable in a virtualized
environment where a pf may increment the counter and then have the kernel
crash around it preventing the counter from ever reaching zero.
In the new implementation the scenario described will result in the PF timing
out against the mcp, which will clear the PF's bit in the bitmask allowing
recovery process to proceed.

Subject: [PATCH 0596/6423] bnx2x: Recovery flow bug fixes

1. Sample mcp pulse and mcp sequence in nic load instead of in init_one
as they may change by the time we want to use them.

2. Allow cnic to access device during nic load (by adding a new "LOADING" state
to recovery flow). This prevents the unnecessary cnic timeout which resulted
by cnic attempting to access because nic is loading, but being blocked because
of the Recovery state.

3. Issue 'fake' driver load command to mcp when last driver unloads to prevent
mcp from taking ownership. When recovery is complete unload fake driver to
allow mcp to initialize the hardware before first driver loads.

Subject: [PATCH 0599/6423] ASoC: wm8996: Handle failures to determine
 accessory polarity

If we get an indeterminate impedance with both headset polarities then
give up and report the accessory as a headphone rather than continually
retrying.

Report any accessory with a low impedance as a headphone, previously
anything other than a short or microphone would not be reported at all.
The most likely reason is a microphone with incorrect polarity.

Subject: [PATCH 0601/6423] be2net: allocate more headroom in incoming skbs

Allocation of 64 bytes in skb headroom is not enough if we have to pull
ethernet + ipv6 + tcp headers, and/or extra tunneling header.

Its currently not noticed because netdev_alloc_skb_ip_align(64) give us
more room, thanks to power-of-two kmalloc() roundups.

Make sure we ask for 128 bytes so that side effects of upcoming patches
from Ian Campbell dont decrease benet rx performance, because of extra
skb head reallocations.

Subject: [PATCH 0603/6423] usb: cdc-wdm: Add device-id for Huawei 3G/LTE
 modems
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[v2: Editorial changes suggested by Sergei Shtylyov]

These modems use the Qualcomm MSM Interface (QMI) protocol for
management of their CDC ECM like wwan interface.  This driver
is perfect for exporting the protocol to userspace.

The created character device will be indistinguishable from a
common AT command based Device Management interface, so
userspace applications must do some intelligent matching
on the USB device.

Subject: [PATCH 0604/6423] debugfs: add mode, uid and gid options

Cautious admins may want to restrict access to debugfs. Currently a
manual chown/chmod e.g. in an init script is needed to achieve that.
Distributions that want to make the mount options configurable need
to add extra config files. By allowing to set the root inode's uid,
gid and mode via mount options no such hacks are needed anymore.
Instead configuration becomes straight forward via fstab.

From d9dc878769f521f494d1617d7cd0c92073df75d8 Mon Sep 17 00:00:00 2001

Subject: [PATCH 0607/6423] PCMCIA: soc_common: add GPIO support for card
 status signals

Add GPIO support for reading the card status (card detect, ready,
battery voltage detect) signals into soc_common code.  As we want
interrupts from these GPIOs, this takes over the old irq handling
infrastructure for card status signals, which will now be managed
entirely by the soc_common code.

Subject: [PATCH 0619/6423] x86-64: Fix memcpy() to support sizes of 4Gb and
 above

While currently there doesn't appear to be any reachable in-tree
case where such large memory blocks may be passed to memcpy(),
we already had hit the problem in our Xen kernels. Just like
done recently for mmeset(), rather than working around it,
prevent others from falling into the same trap by fixing this
long standing limitation.

Subject: [PATCH 0620/6423] x86-64: Handle byte-wise tail copying in memcpy()
 without a loop

While hard to measure, reducing the number of possibly/likely
mis-predicted branches can generally be expected to be slightly
better.

Other than apparent at the first glance, this also doesn't grow
the function size (the alignment gap to the next function just
gets smaller).

Subject: [PATCH 0621/6423] ipv4/ipv6: Prepare for new route gateway semantics.

In the future the ipv4/ipv6 route gateway will take on two types
of values:

1) INADDR_ANY/IN6ADDR_ANY, for local network routes, and in this case
   the neighbour must be obtained using the destination address in
   ipv4/ipv6 header as the lookup key.

2) Everything else, the actual nexthop route address.

So if the gateway is not inaddr-any we use it, otherwise we must use
the packet's destination address.

Subject: [PATCH 0623/6423] x86/ioapic: Use legacy_pic to set correct gsi-irq
 mapping

Using compile time NR_LEGACY_IRQS causes the wrong gsi-irq
mapping on non-PC platforms, such as Moorestown. This patch uses
legacy_pic abstraction to set the correct number of legacy
interrupts at runtime. For Moorestown, nr_legacy_irqs = 0. We
have 1:1 mapping for gsi-irq even within the legacy irq range.

Subject: [PATCH 0624/6423] x86/mrst: Set ISA bus type for fake MP IRQs

We use MP IRQs for SFI presented timer interrupts, we should
also set mp_bus_not_pci for MP_ISA_BUS so that pin_2_irq mapping
is correct.

Subject: [PATCH 0631/6423] sfc: Remove fallback for invalid permanent MAC
 address

By the time we look at the MAC address in efx_probe_port(), either the
driver or the firmware has already validated the board configuration.
The possibility of having an invalid MAC address just isn't worth
considering.  It certainly isn't worth having a compile-time option
for this.

Subject: [PATCH 0632/6423] sfc: Make handling of MC reboot more reliable

When the MC reboots, either as part of a firmware upgrade or due to a
bug, it attempts to complete (with an error) any requests that were
outstanding before the reboot.  Since there is an inherent race
condition in checking this, it will also write to a status word in
shared memory.

If we look at each of these separately, we may detect each reboot
twice, resulting in a spurious command failure after a firmware
upgrade or frustrating recovery from a firmware bug.  Instead, if a
request completion indicates a reboot, we must poll and clear the
status word.

This bug was previously masked by use of an incorrect address for the
status word.  Fix that, using the definition now included in
mcdi_pcol.h.

Subject: [PATCH 0634/6423] sfc: Hold efx_nic::stats_lock while reading
 efx_nic::mac_stats

efx_nic::stats_lock is used to serialise stats updates, but each
reader was dropping it before it finished reading efx_nic::mac_stats.

If there were concurrent stats reads using procfs, or one using procfs
and one using ethtool, an update could race with a read.  On a 32-bit
system, the reader could see word-tearing of 64-bit stats (32 bits of
the old value and 32 bits of the new).

Subject: [PATCH 0635/6423] sfc: Merge efx_mac_operations into efx_nic_type

No NICs need to switch efx_mac_operations at run-time, and the MAC
operations are fairly closely bound to NIC types.

Move efx_mac_operations::reconfigure to efx_nic_type::reconfigure_mac
and efx_mac_operations::check_fault fo efx_nic_type::check_mac_fault.
Change callers to call through efx->type or directly if the NIC type
is known.

Remove efx_mac_operations::update_stats.  The implementations for
Falcon used to fetch MAC statistics synchronously and this was used by
efx_register_netdev() to clear statistics after running self-tests.
However, it now only converts statistics that have already been
fetched (and that only for Falcon), and the call from
efx_register_netdev() has no effect.

Subject: [PATCH 0636/6423] sfc: Merge efx_mcdi_mac_check_fault() and
 efx_mcdi_get_mac_faults()

The latter is only called by the former, which is a very short
wrapper.  Further, gcc 4.5 may currently wrongly warn that the
'faults' variable may be used uninitialised.

Subject: [PATCH 0637/6423] sfc: Remove efx_nic_type::push_multicast_hash
 operation

Both implementations of efx_nic_type::reconfigure_mac operation
push the multicast hash filter to the hardware.  It is therefore
redundant to call efx_nic_type::push_multicast_hash as well.

efx_mcdi_mac_reconfigure() also uses this operation, but the
implementation for Siena just uses MCDI anyway.  Merge that into
efx_mcdi_mac_reconfigure().

Subject: [PATCH 0638/6423] sfc: Consistently test DEBUG macro, not
 EFX_ENABLE_DEBUG

The netif_dbg() macro is defined in <linux/netdevice.h>.  If the DEBUG
macro is defined, it logs a message at 'debug' level, otherwise it
does nothing.

In net_driver.h we define DEBUG if EFX_ENABLE_DEBUG is defined, but
this is too late for those source files that already got a
definition of netif_dbg() by including <linux/netdevice.h>

Get rid of EFX_ENABLE_DEBUG, and only define and test DEBUG.

In mtd.c, we do not use DEBUG as a condition flag but are forced to
use the DEBUG macro-function from <linux/mtd/mtd.h>.  Undefine DEBUG
before including it.

Subject: [PATCH 0640/6423] sfc: Correct interrupt timer quantum for Siena
 (normal and turbo mode)

We currently assume that the timer quantum for Siena is 5 us, the same
as for Falcon.  This is not correct; timer ticks are generated on a
rota which takes a minimum of 768 cycles (each event delivery or other
timer change will delay it by 3 cycles).  The timer quantum should be
6.144 or 3.072 us depending on whether turbo mode is active.

Replace EFX_IRQ_MOD_RESOLUTION with a timer_quantum_ns field in struct
efx_nic, initialised by the efx_nic_type::probe function.

While we're at it, replace EFX_IRQ_MOD_MAX with a timer_period_max
field in struct efx_nic_type.

Subject: [PATCH 0641/6423] sfc: Remove dependence on NAPI polling in
 efx_test_eventq_irq()

We cannot safely assume that the NAPI handler will complete within the
20 ms that we allow for the event self-test.  The handler may be
deferred for longer than this, particularly on realtime kernels.

Instead, check whether either an event has been handled or (as in the
old failure path) whether an interrupt has been received and an event
has been delivered but not yet handled.  Use napi_disable() to
synchronize with the NAPI handler before checking, since it will
clear events before updating eventq_read_ptr.

Remove the test result chan.N.eventq.poll, since it is not an error
if the NAPI handler does not run during the test.

Subject: [PATCH 0642/6423] Partly revert "sfc: Handle serious errors in
 exactly one interrupt handler"

This reverts commit 6369545945b90daa1a73fca174da9194c398417c in
drivers/net/ethernet/sfc/falcon.c.

Unlike the INT_ISR0 register on later controller revisions, the
NET_IVEC_INT_Q bits written to memory are only ever set for
interrupting event queues, not for any other interrupt sources.

By definition there can only be one legacy interrupt handler per
function, so there is no need to worry about detecting a fatal
interrupt more than once.

Subject: [PATCH 0643/6423] sfc: Clean up test interrupt handling

Interrupts are normally generated by the event queues, moderated by
timers.  However, they may also be triggered by detection of a 'fatal'
error condition (e.g. memory parity error) or by the host writing to
certain CSR fields as part of a self-test.

The IRQ level/index used for these on Falcon rev B0 and Siena is set
by the KER_INT_LEVE_SEL field and cached by the driver in
efx_nic::fatal_irq_level.  Since this value is also relevant to
self-tests rename the field to just 'irq_level'.

Avoid unnecessary cache traffic by using a per-channel 'last_irq_cpu'
field and only writing to the per-controller field when the interrupt
matches efx_nic::irq_level.  Remove the volatile qualifier and use
ACCESS_ONCE in the places we read these fields.

Subject: [PATCH 0644/6423] sfc: Add hwmon driver for boards using
 SFC9000-family controllers

The SFC9000-family controllers have firmware to manage all board
peripherals including temperature, heat sink continuity and voltage
sensors.  The firmware reports sensor alarms, which we log, and
will shut down the board if necessary.

Some users may want to monitor their boards more closely, so add an
hwmon driver that exposes all sensors reported by the firmware.  Move
efx_mcdi_sensor_event() into the new file so it can share the array of
sensor labels with the hwmon driver.

Subject: [PATCH 0647/6423] sfc: Remove remnants of on-load self-test

The out-of-tree version of the sfc driver used to run a self-test on
each device before registering it.  Although this was never included
in-tree, some functions have checks for this special case which is not
really possible.

Subject: [PATCH 0652/6423] sfc: Make all MAC statistics consistently 64 bits
 wide

Currently we use type u64 for byte counts, which can very quickly
exceed 2^32, and unsigned long for packet counts, which do not.  But
it can still take only 20-something minutes to send or receive 2^32
packets, and not all tools properly handle overflow even if they
sample more often than this.

The MAC statistics are all updated synchronously, so it costs very
little to make them all 64-bit regardless of native word size.

Subject: [PATCH 0655/6423] Add driver auto probing for x86 features v4

There's a growing number of drivers that support a specific x86 feature
or CPU.  Currently loading these drivers currently on a generic
distribution requires various driver specific hacks and it often
doesn't work.

This patch adds auto probing for drivers based on the x86 cpuid
information, in particular based on vendor/family/model number
and also based on CPUID feature bits.

For example a common issue is not loading the SSE 4.2 accelerated
CRC module: this can significantly lower the performance of BTRFS
which relies on fast CRC.

Another issue is loading the right CPUFREQ driver for the current CPU.
Currently distributions often try all all possible driver until
one sticks, which is not really a good way to do this.

It works with existing udev without any changes. The code
exports the x86 information as a generic string in sysfs
that can be matched by udev's pattern matching.

This scheme does not support numeric ranges, so if you want to
handle e.g. ranges of model numbers they have to be encoded
in ASCII or simply all models or families listed. Fixing
that would require changing udev.

Another issue is that udev will happily load all drivers that match,
there is currently no nice way to stop a specific driver from
being loaded if it's not needed (e.g. if you don't need fast CRC)
But there are not that many cpu specific drivers around and they're
all not that bloated, so this isn't a particularly serious issue.

Originally this patch added the modalias to the normal cpu
sysdevs. However sysdevs don't have all the infrastructure
needed for udev, so it couldn't really autoload drivers.
This patch instead adds the CPU modaliases to the cpuid devices,
which are real devices with full support for udev. This implies
that the cpuid driver has to be loaded to use this.

This patch just adds infrastructure, some driver conversions
in followups.

Thanks to Kay for helping with some sysfs magic.

v2: Constifcation, some updates
v4: (trenn@suse.de):
    - Use kzalloc instead of kmalloc to terminate modalias buffer
    - Use uppercase hex values to match correctly against hex values containing
      letters

Subject: [PATCH 0656/6423] crypto: Add support for x86 cpuid auto loading for
 x86 crypto drivers

Add support for auto-loading of crypto drivers based on cpuid features.
This enables auto-loading of the VIA and Intel specific drivers
for AES, hashing and CRCs.

Requires the earlier infrastructure patch to add x86 modinfo.
I kept it all in a single patch for now.

I dropped the printks when the driver cpuid doesn't match (imho
drivers never should print anything in such a case)

One drawback is that udev doesn't know if the drivers are used or not,
so they will be unconditionally loaded at boot up. That's better
than not loading them at all, like it often happens.

Subject: [PATCH 0657/6423] intel-idle: convert to x86_cpu_id auto probing

With this it should be automatically loaded on suitable systems by
udev.

The old switch () is replaced with a table based approach, this
also cleans up the code.

Subject: [PATCH 0658/6423] ACPI: Load acpi-cpufreq from processor driver
 automatically

The only left over hole in automatic cpufreq driver loading was the loading
of ACPI cpufreq. This driver should be loaded when ACPI supports a _PDC
method and the CPU vendor wants to use acpi cpufreq.

Simply add a request module call to the acpi processor core driver
when this is true. This seems like the simplest solution for this.

Subject: [PATCH 0661/6423] X86: Introduce HW-Pstate scattered cpuid feature

It is rather similar to CPB (boot capability) feature
and exists since fam10h (can be looked up in AMD's BKDG).

The feature is needed for powernow-k8 to cleanup init functions and to
provide proper autoloading matching with the new x86cpu modalias
feature.

Subject: [PATCH 0662/6423] cpufreq: Add support for x86 cpuinfo auto loading
 v4

This marks all the x86 cpuinfo tables to the CPU specific device drivers,
to allow auto loading by udev. This should simplify the distribution
startup scripts for this greatly.

I didn't add MODULE_DEVICE_IDs to the centrino and p4-clockmod drivers,
because those probably shouldn't be auto loaded and the acpi driver
be used instead (not fully sure on that, would appreciate feedback)

The old nforce drivers autoload based on the PCI ID.

ACPI cpufreq is autoloaded in another patch.

v3: Autoload gx based on PCI IDs only. Remove cpu check (Dave Jones)
v4: Use newly introduce HW_PSTATE feature for powernow-k8 loading

Subject: [PATCH 0664/6423] CPU: Introduce ARCH_HAS_CPU_AUTOPROBE and X86 parts

This patch is based on Andi Kleen's work:
Implement autoprobing/loading of modules serving CPU
specific features (x86cpu autoloading).

And Kay Siever's work to get rid of sysdev cpu structures
and making use of struct device instead.

Before, the cpuid driver had to be loaded to get the x86cpu
autoloading feature. With this patch autoloading works through
the /sys/devices/system/cpu object

Subject: [PATCH 0665/6423] USB/PCI/PCMCIA: Clean up new_id and remove_id sysfs
 attribute routines

This patch (as1514) cleans up some places where new_id and remove_id
sysfs attributes are created and deleted.  Handling both attributes in
a single routine rather than a pair of routines makes the code
smaller.  It also prevents certain kinds of errors, like one we
currently have in the USB subsystem: The removeid attribute is often
created even when newid isn't (because the driver's no_dynamid_id flag
is set).

In the case of the PCMCIA subsystem, the newid attribute is created
but never explicitly deleted.  The patch adds a deletion routine.

From d4e33fac2408d37f7b52e80ca2a89f9fb482914f Mon Sep 17 00:00:00 2001

Subject: [PATCH 0666/6423] serial: Kill off NO_IRQ

We transform the offenders into a test of irq <= 0 which will be ok while
the ARM people get their platform sorted. Once that is done (or in a while
if they don't do it anyway) then we will change them all to !irq checks.

For arch specific drivers that are already using NO_IRQ = 0 we just test
against zero so we don't need to re-review them later.

Subject: [PATCH 0667/6423] e1000e: disable Early Receive DMA on ICH LOMs

Internal stress testing with jumbo frames shows the reliability of ICH9 and
ICH10D devices is improved in certain corner cases by disabling the Early
Receive feature. To reduce the performance impact caused by disabling this
feature, the packet buffer sizes and relevant flow control settings are
modified accordingly.

Subject: [PATCH 0668/6423] e1000e: update workaround for 82579 intermittently
 disabled during S0->Sx

The workaround which toggles the LANPHYPC (LAN PHY Power Control) value bit
to force the MAC-Phy interconnect into PCIe mode from SMBus mode during
driver load and resume should always be done except if PHY resets are
blocked by the Manageability Engine (ME).  Previously, the toggle was done
only if PHY resets are blocked and the ME was disabled.

The rest of the patch is just indentation changes as a consequence of the
updated workaround.

 NVM when going to Sx

When going to Sx with an ICHx/PCH device, the default Low Power Link Up
(LPLU, a.k.a. reverse auto-negotiation) behavior should be whatever is set
in the NVM.  However, the function e1000_suspend_workarounds_ich8lan()
called when going to Sx always enabled LPLU in all power states.

 multiple lines

To ease searching for debug message strings, concatenate strings that span
multiple lines even if the resulting line exceeds 80 columns; these will
not cause checkpatch warnings.

Also, add '\n' and remove unnecessary '\r' from a few debug strings.

Subject: [PATCH 0676/6423] e1000e: split lib.c into three more-appropriate
 files

The generic lib.c file contains code relative to the various MACs, NVM and
Manageability supported by the driver.  This patch splits the file into
three which are specific to those areas similar to how the PHY-specific
code is in phy.c and code specific to the 80003es2lan, 8257x, and ichX
MAC families are in their own files.  The generic code that is applicable
to all MAC/PHY parts supported by the driver remains in netdev.c, param.c
and ethtool.c files.  No change in functionality, just moving code
around for ease of maintenance, with some whitespace and other checkpatch
cleanups.

From c8aa130b74cc5b112cb2b119d3b477abaaf6e5b2 Mon Sep 17 00:00:00 2001

Date: Fri, 27 Jan 2012 15:22:07 +0900
Subject: [PATCH 0678/6423] PM / Domains: Add OF support

A device node pointer is added to generic pm domain structure to associate
the domain with a node in the device tree. The platform code parses the
device tree to find available nodes representing the generic power domain,
instantiates the available domains and initializes them by calling
pm_genpd_init().

Nodes representing the devices include a phandle of the power domain to
which it belongs. As these devices get instantiated, the driver code
checkes for availability of a power domain phandle, converts the phandle
to a device node and uses the new pm_genpd_of_add_device() api to
associate the device with a power domain.

pm_genpd_of_add_device() runs through its list of registered power domains
and matches the OF node of the domain with the one specified as the
parameter. If a match is found, the device is associated with the matched
domain.

Subject: [PATCH 0679/6423] ARM: EXYNOS: Hook up power domains to generic power
 domain infrastructure

Add support for generic power domain for Exynos4 platforms and remove the
Samsung specific power domain control for Exynos4.

The generic power domain infrastructure is used to control the power domains
available on Exynos4. For non-dt platforms, the power domains are statically
instantiated. For dt platforms, the power domain nodes found in the device
tree are instantiated.

+* Samsung Exynos Power Domains
+
+Exynos processors include support for multiple power domains which are used
+to gate power to one or more peripherals on the processor.
+
+Required Properties:
+- compatiable: should be one of the following.
+    * samsung,exynos4210-pd - for exynos4210 type power domain.
+- reg: physical base address of the controller and length of memory mapped
+    region.
+
+Optional Properties:
+- samsung,exynos4210-pd-off: Specifies that the power domain is in turned-off
+    state during boot and remains to be turned-off until explicitly turned-on.
+
+Example:
+
+	lcd0: power-domain-lcd0 {
+		compatible = "samsung,exynos4210-pd";
+		reg = <0x10023C00 0x10>;
+	};

Subject: [PATCH 0681/6423] r8169: remove rtl8169_reinit_task.

I see no good reason to keep both rtl8169_reinit_task and rtl8169_reset_task:
- rtl8169_reinit_task adds a software failure point which does relate to
  any hardware state
- they handle hardware the same. Remember that rtl8169_reinit_task was
  introduced in the 8169 only era to handle PCI errors way before the 8168
  asked for pll and firmware ops and compare :

      rtl8169_reinit_task     |    rtl8169_reset_task

Subject: [PATCH 0682/6423] r8169: stop delaying workqueue.

Though motivated by the move of the driver to a single work queue of
sequential events and removal of hard irq processing, it looks safe as
a standalone change.

Subject: [PATCH 0686/6423] ASoC: Set idle_bias_off flag in
 snd_soc_codec_driver

Since commit 33c5f969 "ASoC: Allow idle_bias_off to be specified in CODEC
drivers", now we can set idle_bias_off flag in struct snd_soc_codec_driver
for devices can unconditionally support idle_bias_off.

Subject: [PATCH 0692/6423] mac80211: make beacon filtering per virtual
 interface

Due to firmware limitations, we may not be able to
support beacon filtering on all virtual interfaces.
To allow this in mac80211, introduce per-interface
driver capability flags that the driver sets when
an interface is added.

Subject: [PATCH 0696/6423] {nl,cfg,mac}80211: Add support of setting
 non-forwarding entity in Mesh

A mesh node that joins the mesh network is by default a forwarding entity. This patch allows
the mesh node to set as non-forwarding entity. Whenever dot11MeshForwarding is set to 0, the
mesh node can prevent itself from forwarding the traffic which is not destined to him.

Subject: [PATCH 0707/6423] mac80211: Do not scan for IBSS merge with a fixed
 BSSID.

Currently, when we are on an IBSS network with no active station,
we would scan for other BSSID, even if fixed_bssid is on,  due to
a bug in ibss.c,  where fixed_channel would be checked instead of
fixed_bssid.  This would trigger useless scans where scan results
would not be used anyway.

This patch also reverts commit 39d02a7d90602d4557ee05db2a157a4e0,
which assumed that the ifibss->fixed_channel check was legitimate
to disable single-channel scans.  IBSS single-channel scan should
now be fixed.

Subject: [PATCH 0710/6423] r8169: remove work from irq handler.

The irq handler was a mess.

See 7ab87ff4c770eed71e3777936299292739fcd0fe ("via-rhine: move work from
irq handler to softirq and beyond") for similar changes. One can notice:
- all non-napi tasks are explicitely scheduled trough a single work queue.
- hiding software tx queue start behind the rtl_hw_start method is mildly
  natural. Move it in the caller where needed.
- as can be seen from the heavy use of bh disabling locks, the driver is
  not safe for irq context messages with netconsole. It is still quite
  usable for general messaging though. Tested ok with concurrent registers
  dump (ethtool -d) + background traffic + "echo t > /proc/sysrq-trigger".

Tested with old PCI chipset, PCIe 8168 and 810x:
- XID 0c900800 RTL8168evl/8111evl
- XID 18000000 RTL8168b/8111b
- XID 98000000 RTL8169sc/8110sc
- XID 083000c0 RTL8168d/8111d
- XID 081000c0 RTL8168d/8111d
- XID 00b00000 RTL8105e
- XID 04a00000 RTL8102e

As a side note, the comments in f11a377b3f4e897d11f0e8d1fc688667e2f19708
("r8169: avoid losing MSI interrupts") does not seem completely clear: if
I hack the driver further to stop acking the irq link event bit, MSI
interrupts keep being delivered (RTL8168b/8111b, XID 18000000).

Subject: [PATCH 0713/6423] ipv6: ndisc: Convert to dst_neigh_lookup()

Now all code paths grab a local reference to the neigh, so if neigh
is not NULL we unconditionally release it at the end.  The old logic
would only release if we didn't have a non-NULL 'rt'.

Subject: [PATCH 0718/6423] iwlwifi: fix uCode event tracing

Fix multiple bugs in event tracing:

1) If you enable uCode tracing with the device down,
   it will still attempt to access the device and
   continuously log "MAC is in deep sleep!" errors.
   Fix this by only starting logging when the device
   is actually alive.

2) Now you can set the flag when the device is down,
   but logging doesn't happen when you bring it up.
   To fix that, start logging when the device comes
   alive. This means we don't log before -- we could
   do that but I don't need it right now.

3) For some reason we read the error instead of the
   event log -- use the right pointer.

4) Optimise SRAM reading of event log header.

5) Fix reading write pointer == capacity, which can
   happen due to racy SRAM access

6) Most importantly: fix an error where we would try
   to read WAY too many events (like 2^32-300) when
   we read the wrap counter before it is updated by
   the uCode -- this does happen in practice and will
   cause the driver to hang the machine.

7) Finally, change the timer to 10ms instead of 100ms
   as 100ms is too slow to capture all data with a
   normal event log and with 100ms the log will wrap
   multiple times before we have a chance to read it.

Subject: [PATCH 0720/6423] iwlwifi: always restrict scan dwell in P2P

Whenever the PAN (P2P) context is active, it
has timers in the uCode that prevent sleep,
so scanning can't be out of channel for more
than the beacon interval programmed into the
device.

Before this patch, a full scan including any
passive channels when P2P was active would
stall forever because it wouldn't find time
to execute the passive requests (for default
beacon intervals of 100 TU.)

Subject: [PATCH 0723/6423] video: da8xx-fb: reset LCDC only if functional
 clock changes with DVFS

LCDC functional clock may or may not be derived from CPU/MPU DPLL,
For example,
AM335x => Separate independent DPLL for LCDC
Davinci => Same DPLL as MPU

So, on platforms where LCDC functional clock is not derived from CPU/MPU
PLL it is not required to reset LCDC module as its functional clock does
not change with DVFS.

This patch adds check to do reset only if functional clock changes
between pre and post notifier callbacks with DVFS.

Subject: [PATCH 0725/6423] udlfb: remove sysfs framebuffer device with USB
 .disconnect()

The USB graphics card driver delays the unregistering of the framebuffer
device to a workqueue, which breaks the userspace visible remove uevent
sequence. Recent userspace tools started to support USB graphics card
hotplug out-of-the-box and rely on proper events sent by the kernel.

The framebuffer device is a direct child of the USB interface which is
removed immediately after the USB .disconnect() callback. But the fb device
in /sys stays around until its final cleanup, at a time where all the parent
devices have been removed already.

To work around that, we remove the sysfs fb device directly in the USB
.disconnect() callback and leave only the cleanup of the internal fb
data to the delayed work.

Before:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 remove   /2-1.2:1.0/graphics/fb0 (graphics)

After:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)

Subject: [PATCH 0726/6423] drivers/video/au*fb.c: use devm_ functions

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

In au1100fb.c, the probe function now returns -ENODEV on failure.

Subject: [PATCH 0732/6423] drm/i915: set AUD_CONFIG N_value_index for
 DisplayPort

It should be programmed to "0" for HDMI or "1" for DisplayPort.

This enables DisplayPort audio for

- HP EliteBook 8460p
  (whose BIOS does not set the N_value_index bit for us)

- DisplayPort monitor hot plugged after boot
  (otherwise most BIOS will fill the N_value_index bit for us)

Subject: [PATCH 0733/6423] drm/i915: switch ring->id to be a real id

... and add a helpr function for the places where we want a flag.

This way we can use ring->id to index into arrays.

v2: Resurrect the missing beautification-space Chris Wilson noted.
I'm moving this space around because I'll reuse ring_str in the next
patch.

Subject: [PATCH 0734/6423] drm/i915: refactor ring error state capture to use
 arrays

The code already got unwieldy and we want to dump more per-ring
registers.

Only functional change is that we now also capture the video
ring registers on ilk.

v2: fixup a refactor fumble spotted by Chris Wilson.

Subject: [PATCH 0735/6423] drm/i915: collect more per ring error state

Based on a patch by Ben Widawsky, but with different colors
for the bikeshed.

In contrast to Ben's patch this one doesn't add the fault regs.
Afaics they're for the optional page fault support which
- we're not enabling
- and which seems to be unsupported by the hw team. Recent bspec
  lacks tons of information about this that the public docs released
  half a year back still contain.

Also dump ring HEAD/TAIL registers - I've recently seen a few
error_state where just guessing these is not good enough.

v2: Also dump INSTPM for every ring.

v3: Fix a few really silly goof-ups spotted by Chris Wilson.

Subject: [PATCH 0737/6423] drm/i915: Separate fence pin counting from normal
 bind pin counting

In order to correctly account for reserving space in the GTT and fences
for a batch buffer, we need to independently track whether the fence is
pinned due to a fenced GPU access in the batch or whether the buffer is
pinned in the aperture. Currently we count the fenced as pinned if the
buffer has already been seen in the execbuffer. This leads to a false
accounting of available fence registers, causing frequent mass evictions.
Worse, if coupled with the change to make i915_gem_object_get_fence()
report EDADLK upon fence starvation, the batchbuffer can fail with only
one fence required...

Fixes intel-gpu-tools/tests/gem_fenced_exec_thrash

Subject: [PATCH 0738/6423] drm/i915: don't trash the gtt when running out of
 fences

With the fence accounting fixed up in the previous commit not finding
enough fences is a fatal error and userspace bug. Trashing the entire
gtt is not gonna turn up that missing fence, so don't to this by
returning another error thatn ENOSPC.

This has the added benefit that it's easier to distinguish fence
accounting errors from gtt space accounting issues.

TTM serves as precendence for the EDEADLK error code - it returns it
when the reservation code needs resources already blocked by the
current reservation.

Subject: [PATCH 0744/6423] PM / Sleep: Introduce "late suspend" and "early
 resume" of devices

The current device suspend/resume phases during system-wide power
transitions appear to be insufficient for some platforms that want
to use the same callback routines for saving device states and
related operations during runtime suspend/resume as well as during
system suspend/resume.  In principle, they could point their
.suspend_noirq() and .resume_noirq() to the same callback routines
as their .runtime_suspend() and .runtime_resume(), respectively,
but at least some of them require device interrupts to be enabled
while the code in those routines is running.

It also makes sense to have device suspend-resume callbacks that will
be executed with runtime PM disabled and with device interrupts
enabled in case someone needs to run some special code in that
context during system-wide power transitions.

Apart from this, .suspend_noirq() and .resume_noirq() were introduced
as a workaround for drivers using shared interrupts and failing to
prevent their interrupt handlers from accessing suspended hardware.
It appears to be better not to use them for other porposes, or we may
have to deal with some serious confusion (which seems to be happening
already).

For the above reasons, introduce new device suspend/resume phases,
"late suspend" and "early resume" (and analogously for hibernation)
whose callback will be executed with runtime PM disabled and with
device interrupts enabled and whose callback pointers generally may
point to runtime suspend/resume routines.

Subject: [PATCH 0745/6423] PM / Sleep: Introduce generic callbacks for new
 device PM phases

Introduce generic subsystem callbacks for the new phases of device
suspend/resume during system power transitions: "late suspend",
"early resume", "late freeze", "early thaw", "late poweroff",
"early restore".

Subject: [PATCH 0746/6423] PM / Domains: Run late/early device suspend
 callbacks at the right time

After the introduction of the late/early phases of device
suspend/resume during system-wide power transitions it is possible
to make the generic PM domains code execute its default late/early
device suspend/resume callbacks during those phases instead of the
corresponding _noirq phases.  The _noirq device suspend/resume
phases were only used for executing those callbacks, because this
was the only way it could be done, but now we can do better.

Subject: [PATCH 0748/6423] regulator: Add devm_regulator_put in consumer.h

Commit d5ad34f7cb "regulator: Implement devm_regulator_free()"
actually implements devm_regulator_put.
Thus rename devm_regulator_free to devm_regulator_put.

Also add empty devm_regulator_put for !CONFIG_REGULATOR

Subject: [PATCH 0749/6423] regmap: Properly round reg_bytes and val_bytes

For the upcoming 2/6-format, we don't see debugfs output otherwise,
since the current division results in 0. I'd think 10/14 is broken
currently, too.

Subject: [PATCH 0751/6423] drm/i915: add per-ring fault reg to error_state

This was pretty handy when figuring out what exactly went wrong with
ppgtt and it might also be useful when we stop filling the entire gart
with scratch page entries.

Also add the gen6+ DONE reg while at it.

v2: Chris Wilson suggested to allocate the error_state with kzalloc
for better paranoia. Also kill existing spurious clears of the
error_state while at it.

Subject: [PATCH 0753/6423] regulator: tps65910: Sleep control through external
 inputs

Add support for sleep controls of different regulator through
external inputs EN1, EN2 or EN3.
Each regulator's output will be active when its external
input is high and turns to OFF/Low power mode when its
external input is low.
The configuration parameters for sleep control is provided through
board specific platform data.

"not volatile" which is implicit because we cannot read them. Make those
functions use 'regmap_readable' to reuse the checks done there.

Subject: [PATCH 0757/6423] drm/i915: Remove the upper limit on the bo size for
 mapping into the CPU domain

The original intention of comparing the bo against the mappable GTT
limits was to prevent a subsequent faulting of the bo into the GTT from
clearing the entire GTT in vain. However, that was clearly a cut'n'paste
mistake as a CPU mapping never binds the bo into the aperture. Whilst
there may be some merit to limiting the maximum size of the bo to
something that can be utilized by the GPU, that limit itself does not
belong as a safeguard to mmapping the bo, so remove the check entirely.

Subject: [PATCH 0758/6423] sfc: Use a more sensible cast in
 efx_rx_buf_offset()

This function returns the page offset of the buffer, which can be
calculated based on either its DMA address or its virtual address.  It
used to use the virtual address and we would cast that to unsigned
long, as anything smaller would result in a compiler warning.  Now
that it's using the DMA address we should use unsigned int, matching
the return type.  It is also unnecessary to use __force.

Subject: [PATCH 0760/6423] drivers/net: strip unused module code from
 sun3_82586.c

This code is clearly unused, since it has a #error right
in it.  Given the vintage of sun3 hardware, it is probably
safe to assume that there is little interest in adding new
functionality to the driver now, so just delete the unused
block of code.

Subject: [PATCH 0761/6423] net: Allow ipv6 proxies and arp proxies be shown
 with iproute2

Add ability to return neighbour proxies list to caller if
it sent full ndmsg structure and has NTF_PROXY flag set.

Before this patch (and before iproute2 patches):
$ ip neigh add proxy 2001::1 dev eth0
$ ip -6 neigh show
$

After it and with applied iproute2 patches:
$ ip neigh add proxy 2001::1 dev eth0
$ ip -6 neigh show
2001::1 dev eth0  proxy
$

Compatibility with old versions of iproute2 is not broken,
kernel checks for incoming structure size and properly
works if old structure is came.

[v2]
* changed comments style.
* removed useless line with continue and curly bracket.
* changed incoming message size check from equal to more or
  equal.

Subject: [PATCH 0763/6423] ath6kl: fix testmode when fw-2.bin or fw-3.bin is
 used

Testmode (TCMD and ART) was not enabled when fw-2.bin or fw-3.bin files
were available, fix that by fetching testmode file just after the
board file but before rest of the firmware files are fetched.

I also added testmode field to struct ath6kl and moved the module parameter
to core.c. Now all module parameters are grouped in one place.

"ath6kl: Define a structure for connection specific aggregation information"
introduces this. In aggr_conn_init(), vif->aggr_cntxt is assigned to
aggr_conn->aggr_info, but vif->aggr_cntxt is not initialized at this
point, this would end up accessing an invalid pointer in aggregation
receive path. Fix this by passing the correct aggr_info to aggr_conn_init().
The panic trace would look like.

Subject: [PATCH 0765/6423] ath6kl: Re-architect suspend mode handling in
 ath6kl_sdio_suspend

Using this patch, the user can bypass existing auto
suspend mode selection logic and force ath6kl to enter
into the suspend mode what he/she wants.

If the user doesn't choose any suspend mode while doing
insmod of the driver, auto suspend mode selection logic
will kick in and choose suspend mode based on the host
SDIO controller capability.

Generic module parameter is required to specify suspend
mode including Deep Sleep and WOW while doing insmod.
Renaming existing mod param variable suspend_cutpower
would be sufficient to meet this requirement.

New module parameter suspend_mode can take any one of
the below suspend state,
   1. cut power
   2. deep sleep
   3. wow

Subject: [PATCH 0766/6423] ath6kl: Configure WOW patterns while going to
 wow_suspend

First preference is given to the user configured WOW patterns.
If the user doesn't configure any patterns (for ex, via iw command),
the default patterns will be configured based on the current mode
(vif->nw_type) while going to WOW suspend.

Summary of changes:

  * ath6kl_wow_ap() is added to configure the below default
    patterns when the system enters into WOW suspend in AP mode.
      + Unicast IP, EAPOL-like and ARP packet pattern
      + ARP packet pattern
      + mDNS/SSDP/LLMNR pattern
      + DHCP broadcast pattern

 * ath6kl_wow_sta() is added to configure the below default
   patterns when the system enters into WOW suspend in STA mode.
      + Unicast packet pattern
      + mDNS/SSDP/LLMNR pattern

  * Move the user provided WOW patterns configuration code
    from ath6kl_wow_suspend() to a separate function called
    ath6kl_wow_usr().

  * Two argument variable's ('filter' and 'mask) data type in
    ath6kl_wmi_add_wow_pattern_cmd() are changed from 'u8 *' to
    'const u8 *'. This is needed to make all pattern and mask
    arrays to be 'static const u8' in the caller function.

  * New conditional check is added to make sure user
    configured pattern count is within the limit (WOW_MAX_FILTERS_PER_LIST).

Subject: [PATCH 0767/6423] ath6kl: Wait for host sleep mode cmd processed
 event during WOW suspend

For every WMI_SET_HOST_SLEEP_MODE_CMDID command (send from the host),
the firmware sends WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID as
an acknowledgement to the host.

In order to being sync with the firmware, the host has to wait for
WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENT event before going to
the suspend state. This patch ensures ath6kl_wow_suspend() waits
until it gets this event after sending set host sleep mode command.

This patch adds,
 * New command WMI_SET_HOST_SLEEP_MODE_CMD_PROCESSED_EVENTID in
   WMI event table.
 * New WMI function ath6kl_wmi_host_sleep_mode_cmd_prcd_evt_rx()
   to process the event.
 * New flag HOST_SLEEP_MODE_CMD_PROCESSED in VIF flags to record
   the arrival of the event.

Error code ENOTCONN is more suitable than EINVAL to report
when the driver is not in connected state in ath6kl_wow_suspend().

I found this during code review.

Subject: [PATCH 0769/6423] drm/i915: fix swizzle detection for gen3
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It looks like the desktop variants of i915 and i945 also have the DCC
register to control dram channel interleave and cpu side bit6
swizzling.

Unfortunately internal Cspec/ConfigDB documentation for these ancient chips
have already been dropped and there seem to be no archives. Also
somebody thought the swizzling behaviour is surely a worthy secret to
keep and redacted any mention of these fields from the published Intel
datasheets.

I suspect the hw engineers were really proud of the page coloring
they've achieved in their first dual channel dram controller with
bit17 - after all Bspec explains in great length the optimal layout of
page frame numbers modulo 4 for the color and depth buffers, too.
Later on when they've started to work on VT-d they shamefully
discoverd their stupidity and tried to cover the tracks ...

This will also come handy for the gen6+ swizzling support, where the
driver is supposed to control swizzling depending upon dram
configuration.

v2: CxDRB3 are 16 bit regs! Noticed by Chris Wilson.

Subject: [PATCH 0772/6423] Revert "mac80211: Do not scan for IBSS merge with a
 fixed BSSID."

This reverts commit f1e3be1561c43b6bbe2426e34849fb1486dc313b.

Johannes Berg <johannes@sipsolutions.net> thinks that this patch is
incorrect.  I'll defer to his judgment.

Subject: [PATCH 0773/6423] mac80211: station state transition error handling

In the future, when we start notifying drivers,
state transitions could potentially fail. To make
it easier to distinguish between programming bugs
and driver failures:
 * rename sta_info_move_state() to
   sta_info_pre_move_state() which can only be
   called before the station is inserted (and
   check this with a new station flag).
 * rename sta_info_move_state_checked() to just
   plain sta_info_move_state(), as it will be
   the regular function that can fail for more
   than just one reason (bad transition or an
   error from the driver)

This makes the programming model easier -- one of
the functions can only be called before insertion
and can't fail, the other can fail.

Subject: [PATCH 0774/6423] mac80211: Fix incorrect num_sta_ps decrement in
 __sta_info_destroy

When WLAN_STA_PS_DRIVER is set by ieee80211_sta_block_awake the
num_sta_ps counter is not incremented. Hence, we shouldn't decrement
it in __sta_info_destroy if only WLAN_STA_PS_DRIVER is set. This
could result in an incorrect num_sta_ps counter leading to strange side
effects with associated powersaving clients.

Fix this by only decrementing num_sta_ps when WLAN_STA_PS_STA was set
before.

Subject: [PATCH 0775/6423] mac80211: Fix incorrect num_sta_ps decrement in
 ap_sta_ps_end

If the driver blocked this specific STA with the help of
ieee80211_sta_block_awake we won't clear WLAN_STA_PS_STA later but
still decrement num_sta_ps. Hence, the next data frame from this
STA will trigger ap_sta_ps_end again and also decrement num_sta_ps
again leading to an incorrect num_sta_ps counter.

This can result in problems with powersaving clients not waking up
from PS because the TIM calculation might be skipped due to the
incorrect num_sta_ps counter.

Subject: [PATCH 0776/6423] rtlwifi: Move pr_fmt macros to a single location

Although the rtlwifi family of devices contains 11 copies of the pr_fmt
macro, the macro is not defined for all routines that need it. By moving
the macro to wifi.h, a single copy is available for all routines.

From 19468413e8d98d44be8daf0acaf8d576dfc53fa2 Mon Sep 17 00:00:00 2001
From: Simon Wunderlich <simon.wunderlich@s2003.tu-chemnitz.de>
Date: Sat, 28 Jan 2012 17:25:33 +0100
Subject: [PATCH 0778/6423] mac80211: add support for mcs masks

* Handle MCS masks set by the user.
* Match rates provided by the rate control algorithm to the mask set,
  also in HT mode, and switch back to legacy mode if necessary.
* add debugfs files to observate the rate selection

Subject: [PATCH 0779/6423] mac80211: Move num_sta_ps counter decrement after
 synchronize_rcu

Unted the assumption that the sta struct is still accessible before the
synchronize_rcu call we should move the num_sta_ps counter decrement
after synchronize_rcu to avoid incorrect decrements if num_sta_ps.

Subject: [PATCH 0781/6423] iwlwifi: fix uCode event tracing

Fix multiple bugs in event tracing:

1) If you enable uCode tracing with the device down,
   it will still attempt to access the device and
   continuously log "MAC is in deep sleep!" errors.
   Fix this by only starting logging when the device
   is actually alive.

2) Now you can set the flag when the device is down,
   but logging doesn't happen when you bring it up.
   To fix that, start logging when the device comes
   alive. This means we don't log before -- we could
   do that but I don't need it right now.

3) For some reason we read the error instead of the
   event log -- use the right pointer.

4) Optimise SRAM reading of event log header.

5) Fix reading write pointer == capacity, which can
   happen due to racy SRAM access

6) Most importantly: fix an error where we would try
   to read WAY too many events (like 2^32-300) when
   we read the wrap counter before it is updated by
   the uCode -- this does happen in practice and will
   cause the driver to hang the machine.

7) Finally, change the timer to 10ms instead of 100ms
   as 100ms is too slow to capture all data with a
   normal event log and with 100ms the log will wrap
   multiple times before we have a chance to read it.

Subject: [PATCH 0783/6423] iwlwifi: always restrict scan dwell in P2P

Whenever the PAN (P2P) context is active, it
has timers in the uCode that prevent sleep,
so scanning can't be out of channel for more
than the beacon interval programmed into the
device.

Before this patch, a full scan including any
passive channels when P2P was active would
stall forever because it wouldn't find time
to execute the passive requests (for default
beacon intervals of 100 TU.)

Subject: [PATCH 0787/6423] rtlwifi: Convert to asynchronous firmware load

This patch addresses a kernel bugzilla report and two recent mail threads.

The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632,
which reports a udev timeout on boot.

The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/
linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a
suspend/resume cycle for rtl8192cu.

The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.

This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

From 61d1d219c4c0761059236a46867bc49943c4d29d Mon Sep 17 00:00:00 2001

Subject: [PATCH 0788/6423] cgroup: remove extra calls to find_existing_css_set

In cgroup_attach_proc, we indirectly call find_existing_css_set 3
times. It is an expensive call so we want to call it a minimum
of times. This patch only calls it once and stores the result so
that it can be used later on when we call cgroup_task_migrate.

This required modifying cgroup_task_migrate to take the new css_set
(which we obtained from find_css_set) as a parameter. The nice side
effect of this is that cgroup_task_migrate is now identical for
cgroup_attach_task and cgroup_attach_proc. It also now returns a
void since it can never fail.

Changes in V5:
* https://lkml.org/lkml/2012/1/20/344 (Tejun Heo)
  * Remove css_set_refs
Changes in V4:
* https://lkml.org/lkml/2011/12/22/421 (Li Zefan)
  * Avoid GFP_KERNEL (sleep) in rcu_read_lock by getting css_set in
    a separate loop not under an rcu_read_lock
Changes in V3:
* https://lkml.org/lkml/2011/12/22/13 (Li Zefan)
  * Fixed earlier bug by creating a seperate patch to remove tasklist_lock
Changes in V2:
* https://lkml.org/lkml/2011/12/20/372 (Tejun Heo)
  * Move find_css_set call into loop which creates the flex array
* Author
  * Kill css_set_refs and use group_size instead
  * Fix an off-by-one error in counting css_set refs
  * Add a retval check in out_list_teardown

From ff3d9c3c90c6edcb975c390db3671713899c2842 Mon Sep 17 00:00:00 2001
From: Mark Allyn <mark.a.allyn@intel.com>
Date: Wed, 28 Dec 2011 17:37:59 +0000
Subject: [PATCH 0791/6423] staging: sep: SEP update

This is basically a rewrite so there isn't a nice easy to present way of
providing this as a patch series. This patch is a pull of Mark's new driver into
the upstream staging area. On top of that are a series of patches by
Andy Shevchenko to make it build on the current tree, fix a few things and
even get it passed sparse.

The new driver supports the kernel crypto layer, passes the coding style checks,
passes human taste checks and has proper kernel-doc formatted comments.

I've then folded back in some later fixes it was missing that got applied to
to the kernel tree.

This should be ready for more serious review with a view to migration from
the staging tree shortly.

Subject: [PATCH 0792/6423] drm/i915: fall through pwrite_gtt_slow to the shmem
 slow path

The gtt_pwrite slowpath grabs the userspace memory with
get_user_pages. This will not work for non-page backed memory, like a
gtt mmapped gem object. Hence fall throuh to the shmem paths if we hit
-EFAULT in the gtt paths.

Now the shmem paths have exactly the same problem, but this way we
only need to rearrange the code in one write path.

v2: v1 accidentaly falls back to shmem pwrite for phys objects. Fixed.

v3: Make the codeflow around phys_pwrite cleara as suggested by Chris
Wilson.

Subject: [PATCH 0793/6423] drm/i915: rewrite shmem_pwrite_slow to use
 copy_from_user

... instead of get_user_pages, because that fails on non page-backed
user addresses like e.g. a gtt mapping of a bo.

To get there essentially copy the vfs read path into pagecache. We
can't call that right away because we have to take care of bit17
swizzling. To not deadlock with our own pagefault handler we need
to completely drop struct_mutex, reducing the atomicty-guarantees
of our userspace abi. Implications for racing with other gem ioctl:

- execbuf, pwrite, pread: Due to -EFAULT fallback to slow paths there's
  already the risk of the pwrite call not being atomic, no degration.
- read/write access to mmaps: already fully racy, no degration.
- set_tiling: Calling set_tiling while reading/writing is already
  pretty much undefined, now it just got a bit worse. set_tiling is
  only called by libdrm on unused/new bos, so no problem.
- set_domain: When changing to the gtt domain while copying (without any
  read/write access, e.g. for synchronization), we might leave unflushed
  data in the cpu caches. The clflush_object at the end of pwrite_slow
  takes care of this problem.
- truncating of purgeable objects: the shmem_read_mapping_page call could
  reinstate backing storage for truncated objects. The check at the end
  of pwrite_slow takes care of this.

v2:
- add missing intel_gtt_chipset_flush
- add __ to copy_from_user_swizzled as suggest by Chris Wilson.

v3: Fixup bit17 swizzling, it swizzled the wrong pages.

Subject: [PATCH 0794/6423] drm/i915: rewrite shmem_pread_slow to use
 copy_to_user

Like for shmem_pwrite_slow. The only difference is that because we
read data, we can leave the fetched cachelines in the cpu: In the case
that the object isn't in the cpu read domain anymore, the clflush for
the next cpu read domain invalidation will simply drop these
cachelines.

slow_shmem_bit17_copy is now ununsed, so kill it.

With this patch tests/gem_mmap_gtt now actually works.

v2: add __ to copy_to_user_swizzled as suggested by Chris Wilson.

v3: Fixup the swizzling logic, it swizzled the wrong pages.

Subject: [PATCH 0800/6423] Input: add Cypress TTSP capacitive multi-touch
 screen support

Cypress TrueTouch(tm) Standard Product controllers are found in
a wide range of embedded devices. This driver add support for a
variety of TTSP controllers.

Since the hardware is capable of tracking identifiable contacts, multi-touch
protocol type B (stateful) is used to report contact information.

The driver is composed of a core driver that process the data sent by
the contacts and a set of bus specific interface modules. This patch
adds the base core TTSP driver.

Subject: [PATCH 0801/6423] ASoC: max9768: Fix up review comments in max9768
 driver

The Mute Switch should be called Playback Switch to match the volume
and the regmap core has been updated so we don't need to mark all the
registers as non-volatile.

Subject: [PATCH 0804/6423] regmap: Remove incorrect unreachable comment in
 regcache_set_val()

regcache_set_val() returns false if cache[idx] != val.
Thus it actually is not unreachable.

Subject: [PATCH 0805/6423] usb: musb: make modules behave better

There's really no point in doing all that
initcall trickery when we can safely let
udev handle module probing for us.

Remove all of that trickery, by moving everybody
to module_init() and making proper use of
platform_device_register() rather than
platform_device_probe().

From a915da9b69273815527ccb3789421cb7027b545b Mon Sep 17 00:00:00 2001
From: Eric Dumazet <eric.dumazet@gmail.com>
Date: Tue, 31 Jan 2012 05:18:33 +0000
Subject: [PATCH 0813/6423] tcp: md5: rcu conversion

In order to be able to support proper RST messages for TCP MD5 flows, we
need to allow access to MD5 keys without locking listener socket.

This conversion is a nice cleanup, and shrinks size of timewait sockets
by 80 bytes.

IPv6 code reuses generic code found in IPv4 instead of duplicating it.

Control path uses GFP_KERNEL allocations instead of GFP_ATOMIC.

Subject: [PATCH 0815/6423] staging: nvec: ps2: add suspend/resume functions

This adds suspend and resume functions to the nvec_ps2 mouse driver.

During suspend the nvec sends a "Cancel all mouse events" command. If
this is missed, there will be still some bytes in the received buffer
after resume which make the mouse go out of sync.

Subject: [PATCH 0825/6423] ASoC: core: Support suspend to disk

Use the same pm_ops for all system suspend and resume paths. This isn't
ideal for suspend to disk with older CODECs as we'll suspend and then
resume the CODEC before powering off all of which takes a long time due
to VMID ramps but it's very simple to implement and for modern CODECs the
overhead should be minimal.

 uuid

When a system tries to mount a filesystem (FS) using UUID, the xfs
returns -EINVAL and shows a message if a FS with the same UUID has
been already mounted. It is useful to output the duplicate UUID
with it.

Subject: [PATCH 0832/6423] drm/i915: Handle unmappable buffers during error
 state capture

As the buffer is not necessarily accessible through the GTT at the time
of a GPU hang, and capturing some of its contents is far more valuable
than skipping it, provide a clflushed fallback read path. We still
prefer to read through the GTT as that is more consistent with the GPU
access of the same buffer. So example it will demonstrate any errorneous
tiling or swizzling of the command buffer as seen by the GPU.

This becomes necessary with use of CPU relocations and lazy GTT binding,
but could potentially happen anyway as a result of a pathological error.

There is no limit on number of MD5 keys an application can attach to a
tcp socket.

This patch adds a per tcp socket limit based
on /proc/sys/net/core/optmem_max

With current default optmem_max values, this allows about 150 keys on
64bit arches, and 88 keys on 32bit arches.

From 41de8d4cff21a2e81e3d9ff66f5f7c903f9c3ab1 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Sun, 29 Jan 2012 13:47:52 +0000
Subject: [PATCH 0836/6423] drivers/net: Remove alloc_etherdev error messages

alloc_etherdev has a generic OOM/unable to alloc message.
Remove the duplicative messages after alloc_etherdev calls.

Subject: [PATCH 0837/6423] SUNRPC: remove non-exclusive pipe creation from RPC
 pipefs

This patch-set was created in context of clone of git branch:
git://git.linux-nfs.org/projects/trondmy/nfs-2.6.git.

v2:
1) Rebased of current repo state (i.e. all commits were pulled before apply)

I feel it is ready for inclusion if no objections will appear.

SUNRPC pipefs non-exclusive pipe creation code looks obsolete. IOW, as I see
it, all pipes are creating with unique full path and only once.

Subject: [PATCH 0838/6423] SUNRPC: create RPC pipefs superblock per network
 namespace context

This is the initial step of RPC pipefs virtualization. It changes nothing to
current pipefs behaviour except that mount of pipefs in other than init_net
network namespace context will provide only root tree. No other dentries will
be visible.

Subject: [PATCH 0839/6423] SUNRPC: hold current network namespace while pipefs
 superblock is active

We want to be sure that network namespace is still alive while we have pipefs
mounted.
This will be required later, when RPC pipefs will be mounting only from
user-space context.

Subject: [PATCH 0840/6423] SUNRPC: send notification events on pipefs sb
 creation and destruction

They will be used to notify subscribers about pipefs superblock creation and
destruction.
Subcribers will have to create their dentries on passed superblock on mount
event and destroy otherwise.

Subject: [PATCH 0841/6423] SUNRPC: pipefs dentry lookup helper introduced

In all places, where pipefs dentries are created, only directory inode is
actually required to create new dentry. And all this directories has root
pipefs dentry as their parent. So we actually don't need this pipefs mount
point at all if some pipefs lookup method will be provided.
IOW, all we really need is just superblock and simple lookup method to find
root's child dentry with appropriate name. And this patch introduces this
method.
Note, that no locking implemented in rpc_d_lookup_sb(). So it can be used only
in case of assurance, that pipefs superblock still exist. IOW, we can use this
method only in pipefs mount-umount notification subscribers callbacks.

Subject: [PATCH 0842/6423] SUNRPC: put pipefs superblock link on network
 namespace

We have modules (like, pNFS blocklayout module) which creates pipes on
rpc_pipefs. Thus we need per-net operations for them. To make it possible we
require appropriate super block. So we have to put sb link on network namespace
context. Note, that it's not strongly required to create pipes in per-net
operations. IOW, if pipefs wasn't mounted yet, that no sb link reference will
present on network namespace and in this case we need just need to pass through
pipe creation. Pipe dentry will be created during pipefs mount notification.

Subject: [PATCH 0843/6423] SUNRPC: pipefs per-net operations helper introduced

During per-net pipes creation and destruction we have to make sure, that pipefs
sb exists for the whole creation/destruction cycle. This is done by using
special mutex which controls pipefs sb reference on network namespace context.
Helper consists of two parts: first of them (rpc_get_dentry_net) searches for
dentry with specified name and returns with mutex taken on success. When pipe
creation or destructions is completed, caller should release this mutex by
rpc_put_dentry_net call.

Subject: [PATCH 0845/6423] SUNRPC: replace inode lock with pipe lock for RPC
 PipeFS operations

Currenly, inode i_lock is used to provide concurrent access to SUNPRC PipeFS
pipes. It looks redundant, since now other use of inode is present in most of
these places and thus can be easely replaced, which will allow to remove most
of inode references from PipeFS code. This is a first step towards to removing
PipeFS inode references from kernel code other than PipeFS itself.

From ba9e097593f371ebd102580a0c5b1b2cf55636a0 Mon Sep 17 00:00:00 2001
From: Stanislav Kinsbursky <skinsbursky@parallels.com>
Date: Mon, 26 Dec 2011 15:43:32 +0300
Subject: [PATCH 0846/6423] SUNRPC: split SUNPRC PipeFS pipe data and inode
 creation

Generally, pipe data is used only for pipes, and thus allocating space for it
on every RPC inode allocation is redundant. This patch splits private SUNRPC
PipeFS pipe data and inode, makes pipe data allocated only for pipe inodes.
This patch is also is a next step towards to to removing PipeFS inode
references from kernel code other than PipeFS itself.

Subject: [PATCH 0849/6423] SUNRPC: cleanup GSS pipes usage

Currently gss auth holds RPC inode pointer which is now redundant since it
requires only pipes operations which takes private pipe data as an argument.
Thus this code can be cleaned and all references to RPC inode can be replaced
with privtae pipe data references.

Subject: [PATCH 0850/6423] SUNRPC: split SUNPRC PipeFS dentry and private pipe
 data creation

This patch is a final step towards to removing PipeFS inode references from
kernel code other than PipeFS itself. It makes all kernel SUNRPC PipeFS users
depends on pipe private data, which state depend on their specific operations,
etc.
This patch completes SUNRPC PipeFS preparations and allows to create pipe
private data and PipeFS dentries independently.
Next step will be making SUNPRC PipeFS dentries allocated by SUNRPC PipeFS
network namespace aware routines.

Subject: [PATCH 0851/6423] SUNRPC: handle RPC client pipefs dentries by
 network namespace aware routines

v2:
1) "Over-put" of PipeFS mount point fixed. Fix is ugly, but allows to bisect
the patch set. And it will be removed later in the series.

This patch makes RPC clients PipeFs dentries allocations in it's owner network
namespace context.
RPC client pipefs dentries creation logic has been changed:
1) Pipefs dentries creation by sb was moved to separated function, which will
be used for handling PipeFS mount notification.
2) Initial value of RPC client PipeFS dir dentry is set no NULL now.

RPC client pipefs dentries cleanup logic has been changed:
1) Cleanup is done now in separated rpc_remove_pipedir() function, which takes
care about pipefs superblock locking.

Also this patch removes slashes from cb_program.pipe_dir_name and from
NFS_PIPE_DIRNAME to make rpc_d_lookup_sb() work. This doesn't affect
vfs_path_lookup() results in nfs4blocklayout_init() since this slash is cutted
off anyway in link_path_walk().

Subject: [PATCH 0853/6423] SUNRPC: make SUNPRC clients list per network
 namespace context

This patch moves static SUNRPC clients list and it's lock to sunrpc_net
structure.
Currently this list is used only for debug purposes. But later it will be used
also for selecting clients by networks namespace on PipeFS mount/umount events.
Per-network namespace lists will make this faster and simplier.

Note: client list is taken from "init_net" network namespace context in
rpc_show_tasks(). This will be changed some day later with making SUNRPC
sysctl's per network namespace context.

Subject: [PATCH 0854/6423] SUNRPC: subscribe RPC clients to pipefs
 notifications

This patch subscribes RPC clients to RPC pipefs notifications. RPC clients
notifier block is registering with pipefs initialization during SUNRPC module
init.
This notifier callback is responsible for RPC client PipeFS directory and GSS
pipes creation. For pipes creation and destruction two additional callbacks
were added to struct rpc_authops.
Note that no locking required in notifier callback because PipeFS superblock
pointer is passed as an argument from it's creation or destruction routine and
thus we can be sure about it's validity.

 from RPC clients code

v2:
1) Updated due to changes in the first patch of the series.

Now, with RPC pipefs mount notifications handling in RPC clients, we can remove
mount point creation and destruction. RPC clients dentries will be created on
PipeFS mount event and removed on umount event.

Subject: [PATCH 0861/6423] NFS: DNS resolver cache per network namespace
 context introduced

This patch implements DNS resolver cache creation and registration for each
alive network namespace context.
This was done by registering NFS per-net operations, responsible for DNS cache
allocation/register and unregister/destructioning instead of initialization and
destruction of static "nfs_dns_resolve" cache detail (this one was removed).
Pointer to network dns resolver cache is stored in new per-net "nfs_net"
structure.
This patch also changes nfs_dns_resolve_name() function prototype (and it's
calls) by adding network pointer parameter, which is used to get proper DNS
resolver cache pointer for do_cache_lookup_wait() call.

Note: empty nfs_dns_resolver_init() and nfs_dns_resolver_destroy() functions
will be used in next patch in the series.

Subject: [PATCH 0862/6423] NFS: DNS resolver PipeFS notifier introduced

This patch subscribes DNS resolver caches to RPC pipefs notifications. Notifier
is registering on NFS module load. This notifier callback is responsible for
creation/destruction of PipeFS DNS resolver cache directory.
Note that no locking required in notifier callback because PipeFS superblock
pointer is passed as an argument from it's creation or destruction routine and
thus we can be sure about it's validity.

Subject: [PATCH 0863/6423] NFS: remove RPC PipeFS mount point references from
 NFS cache routines

This is a cleanup patch. We don't need this reference anymore, because DNS
resolver cache now creates it's dentries in per-net operations and on PipeFS
mount/umount notification.
Note that nfs_cache_register_net() now returns 0 instead of -ENOENT in case of
PiepFS superblock absence. This is ok, Dns resolver cache will be regestered on
PipeFS mount event.

Subject: [PATCH 0864/6423] SUNRPC: fix pipe->ops cleanup on pipe dentry unlink

This patch looks late due to GSS AUTH patches sent already. But it fixes a flaw
in RPC PipeFS pipes handling.
I've added this patch in the series, because this series related to pipes. But
it should be a part of previous series named "SUNPRC: cleanup PipeFS for
network-namespace-aware users".

Pipe dentry can be created and destroyed many times during pipe life cycle.
This actually means, that we can't set pipe->ops to NULL in rpc_close_pipes()
and use this variable as a flag, indicating, that pipe's dentry is unlinking.
To follow this restriction, this patch replaces "pipe->ops = NULL" assignment
and checks for NULL with "pipe->dentry = NULL" assignment and checks for
NULL respectively.
This patch also removes check for non-NULL pipe->ops (or pipe->dentry) in
rpc_close_pipes() because it always non-NULL now.

Subject: [PATCH 0865/6423] NFS: make NFS client allocated per network
 namespace context

This patch adds new net variable to nfs_client structure. This variable is set
on NFS client creation and cheched during matching NFS client search.
Initially current->nsproxy->net_ns is used as network namespace owner for new
NFS client to create. This network namespace pointer is set during mount
options parsing and thus can be passed from user-spave utils in future if will
be necessary.

Subject: [PATCH 0869/6423] NFS: idmap PipeFS notifier introduced

v2:
1) Added "nfs_idmap_init" and "nfs_idmap_quit" definitions for kernels built
without CONFIG_NFS_V4 option set.

This patch subscribes NFS clients to RPC pipefs notifications. Idmap notifier
is registering on NFS module load. This notifier callback is responsible for
creation/destruction of PipeFS idmap pipe dentry for NFS4 clients.

Since ipdmap pipe is created in rpc client pipefs directory, we have make sure,
that this directory has been created already. IOW RPC client notifier callback
has been called already. To achive this, PipeFS notifier priorities has been
introduced (RPC clients notifier priority is greater than NFS idmap one).
But this approach gives another problem: unlink for RPC client directory will
be called before NFS idmap pipe unlink on UMOUNT event and will fail, because
directory is not empty.
The solution, introduced in this patch, is to try to remove client directory
once again after idmap pipe was unlinked. This looks like ugly hack, so
probably it should be replaced in some more elegant way.

Note that no locking required in notifier callback because PipeFS superblock
pointer is passed as an argument from it's creation or destruction routine and
thus we can be sure about it's validity.

Subject: [PATCH 0871/6423] NFS: blocklayout pipe creation per network
 namespace context introduced

This patch implements blocklayout pipe creation and registration per each
existent network namespace.
This was achived by registering NFS per-net operations, responsible for
blocklayout pipe allocation/register and unregister/destruction instead of
initialization and destruction of static "bl_device_pipe" pipe (this one was
removed).
Note, than pointer to network blocklayout pipe is stored in per-net "nfs_net"
structure, because allocating of one more per-net structure for blocklayout
module looks redundant.
This patch also changes dev_remove() function prototype (and all it's callers,
where it' requied) by adding network namespace pointer parameter, which is used
to discover proper blocklayout pipe for rpc_queue_upcall() call.

Subject: [PATCH 0872/6423] NFS: blocklayout PipeFS notifier introduced

This patch subscribes blocklayout pipes to RPC pipefs notifications. Notifier
is registering on blocklayout module load. This notifier callback is
responsible for creation/destruction of PipeFS blocklayout pipe dentry.
Note that no locking required in notifier callback because PipeFS superblock
pointer is passed as an argument from it's creation or destruction routine and
thus we can be sure about it's validity.

Subject: [PATCH 0873/6423] NFS: remove RPC PipeFS mount point reference from
 blocklayout routines

This is a cleanup patch. We don't need this reference anymore, because
blocklayout pipes dentries now creates and destroys in per-net operations and
on PipeFS mount/umount notification.
Note that nfs4blocklayout_register_net() now returns 0 instead of -ENOENT in
case of PipeFS superblock absence. This is ok, because blocklayout pipe dentry
will be created on PipeFS mount event.

Again, We're unlikely to ever need more than 2^31 simultaneous lock

Now that there are no more users, we can also get rid of the custom
allocator code.

Subject: [PATCH 0882/6423] NFS: Optimise away unnecessary setattrs for
 open(O_TRUNC);

Currently, we will correctly optimise away a truncate that doesn't
change the file size. However, in the case of open(O_TRUNC), we
also want to optimise away the time changes.

Subject: [PATCH 0883/6423] NFS: Ensure that mmapped pages remain stable during
 writeback

Ensure that nfs_vm_page_mkwrite() waits for the page writeback to
complete before the application is allowed to modify page
contents.
The main reason for wanting to do this in NFS is to ensure that the
server doesn't get confused if we have to resend the RPC request
due to a dropped/missed reply.

Subject: [PATCH 0884/6423] SUNRPC: Fix potential races in
 xprt_lock_write_next()

We have to ensure that the wake up from the waitqueue and the assignment
of xprt->snd_task are atomic. We can do this by assigning the snd_task
while under the waitqueue spinlock.

Subject: [PATCH 0885/6423] SUNRPC: move rpcbind internals to sunrpc part of
 network namespace context

This patch makes rpcbind logic works in network namespace context. IOW each
network namespace will have it's own unique rpcbind internals (clients and
friends) required for registering svc services per network namespace.

Subject: [PATCH 0886/6423] SUNRPC: optimize net_ns dereferencing in rpcbind

Static rpcbind creation functions can be parametrized by network namespace
pointer, calculated only once, instead of using init_net pointer (or taking it
from current when virtualization will be comleted) in many places.

Subject: [PATCH 0891/6423] SUNRPC: parametrize rpc_parse_scope_id() by network
 context

Parametrize rpc_parse_scope_id() by network context and thus force it's caller
to pass in network context instead of using hard-coded "init_net".

Subject: [PATCH 0897/6423] SUNRPC: register service on creation in current
 network namespace

Service, using rpcbind (Lockd, NFSd) are starting from userspace call and thus
we can use current network namespace.
There could be a problem with NFSd service, because it's creation can be called
through NFSd fs from different network namespace. But this is a part of "NFSd
per net ns" task and will be fixed in future.

Subject: [PATCH 0898/6423] SUNRPC: unregister service on creation in current

On service shutdown we can be sure, that no more users of it left except
current. Thus it looks like using current network namespace context is safe in
this case.

This patch prepares infrastructure for network namespace aware cache detail

One note about adding network namespace link to cache structure. It's going to
be used later in NFS DNS cache parsing routine (nfs_dns_parse for rpc_pton()
call).

Subject: [PATCH 0900/6423] SUNRPC: create unix gid cache per network namespace

v2:
1) fixed silly usage of template cache as a real one (this code left from
static global cache for all)

This patch makes unix_gid_cache cache detail allocated and registered per
network namespace context.
Thus with this patch unix_gid_cache contents for network namespace "X" are
controlled from proc file system mount for the same network namespace "X".

From a1db410d0bbadc49943f0fcddb21702ceb429396 Mon Sep 17 00:00:00 2001
From: Stanislav Kinsbursky <skinsbursky@parallels.com>
Date: Thu, 19 Jan 2012 21:42:37 +0400
Subject: [PATCH 0901/6423] SUNRPC: create GSS auth cache per network namespace

This patch makes GSS auth cache details allocated and registered per network
namespace context.
Thus with this patch rsi_cache and rsc_cache contents for network namespace "X"
are controlled from proc file system mount for the same network namespace "X".

Subject: [PATCH 0902/6423] SUNRPC: ip map cache per network namespace cleanup

This patch converts ip_map_cache per network namespace implemenetation to the
same view, as other caches done in the series.
Besides generalization, code becomes shorter with this patch.

Looks like this function survived after some cleanup patch without a reason.
Now it's not called or referenced and I believe, that it can be simply removed.

Subject: [PATCH 0910/6423] SUNRPC: search for service transports in network
 namespace context

Service transports are parametrized by network namespace. And thus lookup of
transport instance have to take network namespace into account.

Subject: [PATCH 0915/6423] NFSv4: Avoid thundering herd issues with
 nfs_release_seqid

Store a pointer to the rpc_task in struct nfs_seqid so that we can wake up
only that request that is able to grab the lock after we've released it.

Subject: [PATCH 0922/6423] tcp: md5: protects md5sig_info with RCU

This patch makes sure we use appropriate memory barriers before
publishing tp->md5sig_info, allowing tcp_md5_do_lookup() being used from
tcp_v4_send_reset() without holding socket lock (upcoming patch from
Shawn Lu)

Note we also need to respect rcu grace period before its freeing, since
we can free socket without this grace period thanks to
SLAB_DESTROY_BY_RCU

Subject: [PATCH 0923/6423] xfrm6: remove unneeded NULL check in
 __xfrm6_output()

We don't check for NULL consistently in __xfrm6_output().  If "x" were
NULL here it would lead to an OOPs later.  I asked Steffen Klassert
about this and he suggested that we remove the NULL check.

On 10/29/11, Steffen Klassert <steffen.klassert@secunet.com> wrote:

Subject: [PATCH 0930/6423] tcp: md5: RST: getting md5 key from listener

TCP RST mechanism is broken in TCP md5(RFC2385). When
connection is gone, md5 key is lost, sending RST
without md5 hash is deem to ignored by peer. This can
be a problem since RST help protocal like bgp to fast
recove from peer crash.

In most case, users of tcp md5, such as bgp and ldp,
have listener on both sides to accept connection from peer.
md5 keys for peers are saved in listening socket.

There are two cases in finding md5 key when connection is
lost:
1.Passive receive RST: The message is send to well known port,
tcp will associate it with listner. md5 key is gotten from
listener.

2.Active receive RST (no sock): The message is send to ative
side, there is no socket associated with the message. In this
case, finding listener from source port, then find md5 key from
listener.

we are not loosing sercuriy here:
packet is checked with md5 hash. No RST is generated
if md5 hash doesn't match or no md5 key can be found.

Subject: [PATCH 0932/6423] pinctrl: delete raw device pointers in pinmux maps

After discussion with Mark Brown in an unrelated thread about
ADC lookups, it came to my knowledge that the ability to pass
a struct device * in the regulator consumers is just a
historical artifact, and not really recommended. Since there
are no in-kernel users of these pointers, we just kill them
right now, before someone starts to use them.

 As you can see we may have several pin controllers on the system and thus
 we need to specify which one of them that contain the functions we wish

Subject: [PATCH 0937/6423] ixgbe: Add module parameter to allow untested and
 unsafe SFP+ modules

The X520 family of network devices, with the 82599 chip, support a
small number of Intel-verified SFP+ modules on their NICs.  To maintain
stability and quality, the current devices restrict untested 3rd party
SFP+ modules.

This patch introduces a module parameter for ixgbe to allow these untested
modules at the user's peril.  It also includes a warning to the syslog
alerting users that the modules aren't supported, and results may
vary.

Subject: [PATCH 0943/6423] ipv6: Remove never used function inet6_ac_check().

It went from unused, to commented out, and never changing after
that.

Just get rid of it, if someone wants it they can unearth it from
the history.

Subject: [PATCH 0944/6423] drivercore: Output common devicetree information in
 uevent

When userspace needs to find a specific device, it currently isn't easy to
resolve a /sys/devices/ path from a specific device tree node.  Nor is it
easy to obtain the compatible list for devices.

This patch generalizes the code that inserts OF_* values into the uevent
device attribute so that any device that is attached to an OF node will
have that information exported to userspace.  Without this patch only
platform devices and some powerpc-specific busses have access to this
data.

The original function also creates a MODALIAS property for the compatible
list, but that code has not been generalized into the common case because
it has the potential to break module loading on a lot of bus types.  Bus
types are still responsible for their own MODALIAS properties.

Boot tested on ARM and compile tested on PowerPC and SPARC.

Both Luis and John reported that they see a compiler warning:

drivers/net/wireless/ath/ath6kl/init.c: In function 'ath6kl_init_hw_params':
drivers/net/wireless/ath/ath6kl/init.c:1377:26: warning: ‘hw’
may be used uninitialized in this function

Oddly enough I have never seen it. But AFAICT the code is correct and
hw is not used uninitalized so add uninitialized_var() to inform that to
the compiler.

Subject: [PATCH 0959/6423] ALSA: hda - Enable sync_write and reset for
 Conexant codecs

This is an attempt to fix S3-resume problems reported for a few
laptops with different Conexant codecs.  They show the communication
stalls at some time in S3, and the driver falls back into the
single-cmd mode.  This leads to the silent output or the lack of
auto-mute feature.

As a workaround, here enables the sync_write and the bus-reset flags
to make the communication more stable.

Subject: [PATCH 0962/6423] HID: logitech: fix mask to enable DJ mode

The user can only experience the bug if she pairs 6 devices to a Unifying
receiver. The sixth paired device would not work.

The value changed is actually a bitmask that enables reporting from each
paired device. As the sixth bit was not set, the sixth device reports are
ignored by the receiver and never get to the driver.

Calling s5m8767_get_reg_id() is exactly the same as calling rdev_get_id().
It is pointless to add s5m8767_get_reg_id() function.
Use rdev_get_id() directly and remove s5m8767_get_reg_id() function.

Subject: [PATCH 0968/6423] ARM: 7309/1: realview: fix unconnected interrupts
 on EB11MP

Since commit 2eac58d (ARM: amba: make use of -1 IRQs warn), we're
able to detect the use of value -1 to indicate the lack of interrupt
line.

The RealView EB, when used with the 11MPCore tile, has a number of
devices without interrupts, and uses the value -1 to indicate this.

Change that value to 0 to conform to the new behaviour.

Subject: [PATCH 0969/6423] ARM: 7280/1: mmc: mmci: Cache MMCICLOCK and
 MMCIPOWER register

Instead of reading a register value everytime we need to
apply a new value for it, maintain a cached copy for it.
This also means we are able to skip writes that are not
needed.

Subject: [PATCH 0970/6423] cgroup: remove cgroup_subsys argument from
 callbacks

The argument is not used at all, and it's not necessary, because
a specific callback handler of course knows which subsys it
belongs to.

Now only ->pupulate() takes this argument, because the handlers of
this callback always call cgroup_add_file()/cgroup_add_files().

So we reduce a few lines of code, though the shrinking of object size
is minimal.

Subject: [PATCH 0971/6423] spi/pl022: Add high priority message pump support

This switches the PL022 worker to a kthread in order to get
hold of a mechanism to control the message pump priority. On
low-latency systems elevating the message kthread to realtime
priority give a real sleek response curve. This has been
confirmed by measurements. Realtime priority elevation for
a certain PL022 port can be requested from platform data.

Subject: [PATCH 0972/6423] tty: serial: OMAP: use a 1-byte RX FIFO threshold
 in PIO mode

In the (default) PIO mode, use a one-byte RX FIFO threshold.  The OMAP
UART IP blocks do not appear to be capable of waking the system under
an RX timeout condition.  Since the previous RX FIFO threshold was 16
bytes, this meant that omap-serial.c did not become aware of any
received data until all those bytes arrived or until another UART
interrupt occurred.  This made the serial console and presumably other
serial applications (GPS, serial Bluetooth) unusable or extremely
slow.  A 1-byte RX FIFO threshold also allows the MPU to enter a
low-power consumption state while waiting for the FIFO to fill.

This can be verified using the serial console by comparing the
behavior when "0123456789abcde" is pasted in from another window, with
the behavior when "0123456789abcdef" is pasted in.  Since the former
string is less than sixteen bytes long, the string is not echoed for
some time, while the latter string is echoed immediately.

DMA operation is unaffected by this patch.

Thanks to Russell King - ARM Linux <linux@arm.linux.org.uk> for some
additional information on the standard behavior of the RX timeout
event, which was used to improve this commit description.

Subject: [PATCH 0973/6423] tty: serial: OMAP: block idle while the UART is
 transferring data in PIO mode

Prevent OMAP UARTs from going idle while they are still transferring
data in PIO mode.  This works around an oversight in the OMAP UART
hardware present in OMAP34xx and earlier: an idle UART won't send a
wakeup when the TX FIFO threshold is reached.  This causes long delays
during data transmission when the MPU powerdomain enters a low-power
mode.  The MPU interrupt controller is not able to respond to
interrupts when it's in a low-power state, so the TX buffer is not
refilled until another wakeup event occurs.

This fix changes the erratum i291 DMA idle workaround.  Rather than
toggling between force-idle and no-idle, it will toggle between
smart-idle and no-idle.  The important part of the workaround is the
no-idle part, so this shouldn't result in any change in behavior.

This fix should work on all OMAP UARTs.  Future patches intended for
the 3.4 merge window will make this workaround conditional on a
"feature" flag, and will use the OMAP36xx+ TX event wakeup support.

Thanks to Kevin Hilman <khilman@ti.com> for mentioning the erratum i291

Date: Wed, 25 Jan 2012 19:50:56 -0700
Subject: [PATCH 0974/6423] tty: serial: omap-serial: wakeup latency constraint
 is in microseconds, not milliseconds

The receive FIFO wakeup latency estimate in the omap-serial driver is
three orders of magnitude too small.  This effectively prevents the
MPU from going to a low-power state when CONFIG_CPU_IDLE=y.  This is a
major power management regression and masks some other FIFO-related
bugs in the driver.

Fix by correcting the most egregious problem in the RX wakeup latency
estimate.  There are several other flaws in the estimator; these will
be fixed by a separate patch series intended for 3.4.

The difference in low-power states with this patch can be observed via
debugfs in pm_debug/count.

This estimate does not have any effect when CONFIG_CPU_IDLE=n.

Subject: [PATCH 0978/6423] qeth: Move away from using neighbour entries in
 qeth_l3_fill_header()

We've moving to a model where dst_entry objects to not have
a reference to the associated neighbour entry, instead such
neighbours must be looked up on-demand.

Here in qeth_l3_fill_header() it's actually much simpler to
use the information in the route itself.  The code is
already conditionalized upon protocol type.

Subject: [PATCH 0979/6423] eicon: fix -Warray-bounds warning

Fix for a -Warray-bounds warning. mixer_notify_update() tries to
write to ((CAPI_MSG *) msg)->info.facility_req.structs[3] while
structs is defined as byte structs[1]. Set all 'structs' which are
part of the typdefs in the info union to 'byte structs[0]'.

v2: set all info.*.structs to byte structs[0]

Subject: [PATCH 0981/6423] iwlwifi: allocate the transport from the bus layer

Change the way we alloc the transport on the way.
Since the transport is allocated from a bus specific area, we can
give the bus specific parameters (i.e. pci_dev for PCI) to the
transport. This will be useful when the bus layer will be killed.

Date: Tue, 3 Jan 2012 13:48:07 +0200
Subject: [PATCH 0985/6423] iwlwifi: the read / write register ops move to
 transport

Most of the accesses to the registers are done from the transport layer.

From 1042db2af183b96cdce5972014d85e8bca0634ad Mon Sep 17 00:00:00 2001
From: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
Date: Tue, 3 Jan 2012 16:56:15 +0200
Subject: [PATCH 0986/6423] iwlwifi: give trans to all the read / write
 functions

From now on, the transport layer in charge of providing access to the
device. So change all the driver to give a pointer to the transport
to all the low level functions that actually access the device.

Subject: [PATCH 0994/6423] iwlwifi: consolidate the start_device flow

Now there is only one transport function that launch a specific fw:
trans_ops->start_fw. This one replaces trans_ops->start_device and
trans_ops->kick_nic. The code that actually loads the fw to the
device has been moved to the transport specific code.

Subject: [PATCH 1000/6423] iwlwifi: stop_hw replace enable_rfkill_int

This trans_ops->stop_hw leaves the RFKILL interrupt enabled,
we can call that one instead of enable_rfkill_int. By that,
we reduce the numbers of acceesses to the NIC from the upper
layers.

 clear

The message was misleading when a queue is deactivated. The fifo
number is irrelevant then, so don't print it.

Subject: [PATCH 1007/6423] usb/uas: only bind if the hcd supports SG

The UAS driver requires SG support by the HCD operating the device. This
patch stops UAS from operating on a HCD without sg support and prints a
message to let him know.

The spec says:
|For [USB2] backward compatibility, the device shall present [BOT] as
|alternate interface zero (primary) and [UAS] as alternate interface one
|(secondary). A device which does not need backward compatibility with
|[BOT] shall present [UAS] as alternate interface zero. In [USB2]
|systems, the [BOT] driver or an associated filter driver may need to
|issue a SET INTERFACE request for alternate interface one and then allow
|the [UAS] driver to load.

If the user used usb_modeswitch to switch to UAS then he can go back to
BOT or use a different HCD. In case UAS is the only interface then there
is currently no way out.
In future usb_sg_wait() should be extended to provide a non-blocking
interface so it can work with the UAS driver.

Subject: [PATCH 1010/6423] usb/uas: make sure data urb is gone if we receive
 status before that

Just run into the following:
- new disk arrived in the system
- udev couldn't wait to get its hands on to to run ata_id /dev/sda
- this sent the cdb 0xa1 to the device.
- my UAS-gadget recevied the cdb and had no idea what to do with it. It
  decided to send a status URB back with sense set to invalid opcode.
- the host side received it status and completed the scsi command.
- the host sent another scsi with 4kib data buffer
- Now I was confused why the data transfer is only 512 bytes instead of
  4kib since the host is always allocating the complete transfer in one
  go.
- Finally the system crashed while walking through the sg list.

This patch adds three new flags in order to distinguish between DATA
URB completed and outstanding. If we receive status before data, we
cancel data and let data complete the command.
This solves the problem for IN and OUT transfers but does not work for
BIDI.

Subject: [PATCH 1012/6423] USB: serial, use tty_standard_install

But before that we need to reorder the calls so that we don't need to
lower the reference counts if usb_autopm_get_interface fails.

Removing the macro, as this is no more needed in the code.
Tried to find the reference when it was last used - but the usage
for this seemed to have been dropped long time ago.

Subject: [PATCH 1015/6423] TTY: pty, remove superfluous ptm test

The code looks like:
if (tty->driver->subtype == PTY_TYPE_MASTER) {
  ...
  if (tty->driver == ptm_driver)

But the second if is superfluous because only the ptm_driver is of
PTY_TYPE_MASTER subtype.

Also we can remove the #if now because devpts_pty_kill is defined as
an empty function for non-CONFIG_UNIX98_PTYS configs.

- * In Linux, we implement the KVP functionality in two components:
- * 1) The kernel component which is packaged as part of the hv_utils driver
- * is responsible for communicating with the host and responsible for
- * implementing the host/guest protocol. 2) A user level daemon that is
- * responsible for data gathering.
- *
- * Host/Guest Protocol: The host iterates over an index and expects the guest
- * to assign a key name to the index and also return the value corresponding to
- * the key. The host will have atmost one KVP transaction outstanding at any
- * given point in time. The host side iteration stops when the guest returns
- * an error. Microsoft has specified the following mapping of key names to
- * host specified index:
- *
- *	Index		Key Name
- *	0		FullyQualifiedDomainName
- *	1		IntegrationServicesVersion
- *	2		NetworkAddressIPv4
- *	3		NetworkAddressIPv6
- *	4		OSBuildNumber
- *	5		OSName
- *	6		OSMajorVersion
- *	7		OSMinorVersion
- *	8		OSVersion
- *	9		ProcessorArchitecture
- *
- * The Windows host expects the Key Name and Key Value to be encoded in utf16.
- *
- * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
- * data gathering functionality in a user mode daemon. The user level daemon
- * is also responsible for binding the key name to the index as well. The
- * kernel and user-level daemon communicate using a connector channel.
- *
- * The user mode component first registers with the
- * the kernel component. Subsequently, the kernel component requests, data
- * for the specified keys. In response to this message the user mode component
- * fills in the value corresponding to the specified key. We overload the
- * sequence field in the cn_msg header to define our KVP message types.
- *
- *
- * The kernel component simply acts as a conduit for communication between the
- * Windows host and the user-level daemon. The kernel component passes up the
- * index received from the Host to the user-level daemon. If the index is
- * valid (supported), the corresponding key as well as its
- * value (both are strings) is returned. If the index is invalid
- * (not supported), a NULL key string is returned.

+ * In Linux, we implement the KVP functionality in two components:

+ * is responsible for communicating with the host and responsible for
+ * implementing the host/guest protocol. 2) A user level daemon that is
+ * responsible for data gathering.
+ *
+ * Host/Guest Protocol: The host iterates over an index and expects the guest
+ * to assign a key name to the index and also return the value corresponding to
+ * the key. The host will have atmost one KVP transaction outstanding at any
+ * given point in time. The host side iteration stops when the guest returns
+ * an error. Microsoft has specified the following mapping of key names to
+ * host specified index:
+ *
+ *	Index		Key Name
+ *	0		FullyQualifiedDomainName
+ *	1		IntegrationServicesVersion
+ *	2		NetworkAddressIPv4
+ *	3		NetworkAddressIPv6
+ *	4		OSBuildNumber
+ *	5		OSName
+ *	6		OSMajorVersion
+ *	7		OSMinorVersion
+ *	8		OSVersion
+ *	9		ProcessorArchitecture
+ *
+ * The Windows host expects the Key Name and Key Value to be encoded in utf16.
+ *
+ * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
+ * data gathering functionality in a user mode daemon. The user level daemon
+ * is also responsible for binding the key name to the index as well. The
+ * kernel and user-level daemon communicate using a connector channel.
+ *
+ * The user mode component first registers with the
+ * the kernel component. Subsequently, the kernel component requests, data
+ * for the specified keys. In response to this message the user mode component
+ * fills in the value corresponding to the specified key. We overload the
+ * sequence field in the cn_msg header to define our KVP message types.
+ *
+ *
+ * The kernel component simply acts as a conduit for communication between the
+ * Windows host and the user-level daemon. The kernel component passes up the
+ * index received from the Host to the user-level daemon. If the index is
+ * valid (supported), the corresponding key as well as its
+ * value (both are strings) is returned. If the index is invalid
+ * (not supported), a NULL key string is returned.

People have complained that debugging code shouldn't alter the flow of
control; it should restrict itself to printing out warnings and error
messages.  Bowing to popular opinion, this patch (as1518) changes the
debugging checks in usb_submit_urb() to follow this guideline.

can_get_echo_skb() is usually called in the TX complete handler.
The stats->tx_packets and stats->tx_bytes should be updated there, too.
This patch simplifies to figure out the size of the sent CAN frame.

Subject: [PATCH 1023/6423] can: flexcan: Fix CAN_RAW_RECV_OWN_MSGS and
 CAN_RAW_LOOPBACK

Currently the flexcan driver uses hardware local echo. This blindly
echos all transmitted frames to all receiving sockets, regardless what
CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to.

This patch now submits transmitted frames to be echoed in the transmit
complete interrupt, preserving the reference to the sending
socket. This allows the can protocol to correctly handle the local
echo.

Further this patch moves tx_bytes statistic accounting into the tx_complete
handler.

Subject: [PATCH 1030/6423] Input: add infrastructure for selecting clockid for
 event time stamps

As noted by Arve and others, since wall time can jump backwards, it is
difficult to use for input because one cannot determine if one event
occurred before another or for how long a key was pressed.

However, the timestamp field is part of the kernel ABI, and cannot be
changed without possibly breaking existing users.

This patch adds a new IOCTL that allows a clockid to be set in the
evdev_client struct that will specify which time base to use for event
timestamps (ie: CLOCK_MONOTONIC instead of CLOCK_REALTIME).

For now we only support CLOCK_MONOTONIC and CLOCK_REALTIME, but
in the future we could support other clockids if appropriate.

The default remains CLOCK_REALTIME, so we don't change the ABI.

Subject: [PATCH 1031/6423] Input: add Synaptics USB device driver

This patch adds a driver for Synaptics USB touchpad or pointing stick
devices. These USB devices emulate an USB mouse by default, so one can
also use the usbhid driver. However, in combination with special user
space drivers this kernel driver allows one to customize the behaviour
of the device.

An extended version of this driver with support for the cPad background
display can be found at
<http://jan-steinhoff.de/linux/synaptics-usb.html>.

Subject: [PATCH 1034/6423] drm: remove master fd restriction on mode setting
 getters

Its useful to be able to call the mode setting getter ioctls.
Not requiring master fd, enables writing a simple program which
can query the state of the video system.

Since these ioctls are only "getters" there is no security or
synchronization issues which would require master fd. Opening
an new fd is already protected by the file permissions on the
device file.

Subject: [PATCH 1036/6423] drm/radeon/kms: remove benchmarks shorter than one
 page

copy_blit operation works only on integral number of pages
so benchmarks shorter than one page size (4K) do not make sense

v2: use RADEON_GPU_PAGE_SIZE instead of "magic" 1024 number and
    sweep sizes between 1 * <page_size> to 16K * <page_size> doubling
    the size in each iteration; we get the same coverage, as
    in the original benchmark, but guarantee integer multiples
    of page size

v3: add whitespace between '*' operator per review received from
    zajec5@gmail.com

Subject: [PATCH 1037/6423] drm/kms: Make i2c buses faster

A udelay value of 20 leads to an I2C bus running at only 25 kbps. I2C
devices can typically operate faster than this, 50 kbps should be fine
for all devices (and compliant devices can always stretch the clock if
needed.)

FWIW, the vast majority of framebuffer drivers set udelay to 10
already. So set it to 10 in DRM drivers too, this will make EDID block
reads faster. We might even lower the udelay value later if no problem
is reported.

Subject: [PATCH 1039/6423] drm/radeon/kms/dce3+: add support for hw i2c using
 atom

Starting with DCE3 hardware, atom contains a general purpose
ProcessI2cChannelTransaction similar to ProcessAuxChannelTransaction.

Add an implementation using the atom tables for DCE3+ hardware.

This should be a little less CPU intensive than bit banging and
may work better in certain cases.

Enable it by setting the radeon hw_i2c module parameter to 1.  E.g.,
radeon.hw_i2c=1
on the kernel command line in grub.

Date: Thu, 5 Jan 2012 09:34:28 -0200
Subject: [PATCH 1040/6423] drm: give up on edid retries when i2c bus is not
 responding

This allows to avoid talking to a non-responding bus repeatedly until we
finally timeout after 15 attempts. We can do this by catching the -ENXIO
error, provided by i2c_algo_bit:bit_doAddress call.

Within the bit_doAddress we already try 3 times to get the edid data, so
if the routine tells us that bus is not responding, it is mostly pointless
to keep re-trying those attempts over and over again until we reach final
number of retries.

This change should fix https://bugs.freedesktop.org/show_bug.cgi?id=41059
and improve overall edid detection timing by 10-30% in most cases, and by
a much larger margin in case of phantom outputs (up to 30x in one worst
case).

Timing results for i915-powered machines for 'time xrandr' command:
Machine 1: from 0.840s to 0.290s
Machine 2: from 0.315s to 0.280s
Machine 3: from +/- 4s to 0.184s

Timing results for HD5770 with 'time xrandr' command:
Machine 4: from 3.210s to 1.060s

Subject: [PATCH 1048/6423] drm fb helper: use drm_helper_connector_dpms to do
 dpms

drm_fb_helper_on|off currently manually searches for encoders
to turn on/off. Make this simpler by using the helper function.

Subject: [PATCH 1057/6423] ASoC: fsi: data push/pop calculation part was
 divided

Next transfer data size of "push" and "pop" had calculated on shared function.
But it was not readable code.
This patch divided it into for push, and for pop.

Subject: [PATCH 1070/6423] ASoC: fsi: PortA/B information was controlled by
 sh_fsi_port_info

Current FSI got each PortA/B parameter by porta_flags/portb_flags from platform.
And .set_rate function was shared for PortA/B.
This structure was not readable and not flexible.
This patch adds sh_fsi_port_info, and its own settings was added on each platform.
it is preparation for DMAEngine support

Subject: [PATCH 1072/6423] ALSA: hda - Add suffix argument to
 snd_hda_add_vmaster()

In most cases, the slave strings for vmaster are identical between
volumes and switches except for "xxx Volume" and "xxx Switch" suffix.
Now snd_hda_add_vmaster() takes the optional suffix argument so that
each string can be composed with the given suffix, and we can share the
slave name strings in both volume and switch calls nicely.

Subject: [PATCH 1074/6423] Define a new function xfs_inode_dquot()

Define a new function xfs_inode_dquot() that takes a inode pointer
and a disk quota type and returns the quota pointer for the specified
quota type.

This simplifies the xfs_qm_dqget() error path significantly.

Subject: [PATCH 1086/6423] drivers/char: comment fix: CMOS RTC update code is
 now in kernel/time/ntp.c

This commit updates some comments to reflect the fact that code
for periodically updating the CMOS RTC was moved to:

  kernel/time/ntp.c

probably by this commit:

  commit 82644459c592a28a3eab682f9b88d81019ddfe8b
  Author: Thomas Gleixner <tglx@linutronix.de>
  Date:   Sat Jul 21 04:37:37 2007 -0700

      NTP: move the cmos update code into ntp.c

      i386 and sparc64 have the identical code to update the cmos clock.  Move it
      into kernel/time/ntp.c as there are other architectures coming along with the
      same requirements.

Subject: [PATCH 1087/6423] gma500, lvds: Fix use after free and mem leak in
 psb_intel_lvds_init()

In psb_intel_lvds_init(), if we fail to allocate memory for
'psb_intel_connector' we free the memory we previously allocated for
'psb_intel_encoder', but we then proceed to use that free'd pointer
when we do 'psb_intel_encoder->dev_priv = lvds_priv;'.

We may also leak the memory we allocated for 'psb_intel_encoder' if we
'goto failed_connector;' and the variable goes out of scope.

While I was there anyway, I also removed the pointless 'if
(psb_intel_connector)' before freeing it at the 'failed_connector:'
label - kfree() deals gracefully with NULL pointers, so it is not
needed.

Subject: [PATCH 1098/6423] ASoC: core: Add support for DAI and machine
 kcontrols.

Currently ASoC can only add kcontrols using codec and platform component device
handles. It's also desirable to add kcontrols for DAIs (i.e. McBSP) and for
SoC card machine drivers too. This allows the kcontrol to have a direct handle to
the parent ASoC component DAI/SoC Card/Platform/Codec device and hence easily
get it's private data.

This change makes snd_soc_add_controls() static and wraps it in the folowing
calls (card and dai are new) :-

snd_soc_add_card_controls()
snd_soc_add_codec_controls()
snd_soc_add_dai_controls()
snd_soc_add_platform_controls()

This patch also does a lot of small mechanical changes in individual codec drivers
to replace snd_soc_add_controls() with snd_soc_add_codec_controls().

It also updates the McBSP DAI driver to use snd_soc_add_dai_controls().

Finally, it updates the existing machine drivers that register controls to either :-

1) Use snd_soc_add_card_controls() where no direct codec control is required.
2) Use snd_soc_add_codec_controls() where there is direct codec control.

In the case of 1) above we also update the machine drivers to get the correct
component data pointers from the kcontrol (rather than getting the machine pointer
via the codec pointer).

From a9bb5a4bf9f84256499c802fd397d56d55227e4f Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Fri, 13 Jan 2012 22:56:32 +0000
Subject: [PATCH 1099/6423] PCMCIA: pxa: convert PXA socket drivers to use new
 irq/gpio management

Convert all the PXA platform socket drivers to use the new irq/gpio
management provided by soc_common.  This relieves these drivers from
having to do anything with these GPIOs other than provide the numbers
to soc_common.

Acked-by: Dominik Brodowski <linux@dominikbrodowski.net>
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

From 81f33c65e6c09597e748288010476861ac5bd166 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Mon, 19 Dec 2011 23:04:22 +0000
Subject: [PATCH 1100/6423] PCMCIA: sa1111: use new per-socket irq/gpio
 infrastructure

Convert sa1111 PCMCIA drivers to use the new per-socket irq/gpio
infrastructure.  As the core takes care of handling the IRQs, we
can get rid of sa1111_pcmcia_socket_init(), sa1111_pcmcia_socket_suspend(),
sa1111_pcmcia_hw_init() and sa1111_pcmcia_hw_shutdown(), as well
as the private IRQ table.

We remove the NCR_0 setting in Neponset, as this is duplicating
what's already done via configure_socket in suspend.

Subject: [PATCH 1101/6423] PCMCIA: sa11x0: assabet: convert to use new
 irq/gpio management

Convert Assabet socket driver to use the new irq/gpio management.
This is slightly more involved because we have to touch the private
platform header file to modify the GPIO bitmasks to be GPIO numbers.

Subject: [PATCH 1104/6423] PCMCIA: sa11x0: nanoengine: convert to use new
 irq/gpio management

Convert Nanoengine socket driver to use the new irq/gpio management.
This is slightly more involved because we have to touch the private
platform header file to modify the GPIO bitmasks to be GPIO numbers.

+
+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.

Subject: [PATCH 1121/6423] enic: Enable support for multiple hardware receive
 queues

This patch enables support for multiple receive queues. If multiple receive
queues are used ingress traffic is hashed into one of the receive queues based
on IP or TCP or both headers. The max number of supported receive queues per
vnic is 8.

Subject: [PATCH 1126/6423] caif-hsi: Add RX flip buffer
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement RX flip buffer in the cfhsi_rx_done function,
piggy-backed frames is also supported.
This gives a significant performance gain for CAIF over HSI.

Subject: [PATCH 1131/6423] crypto: In crypto_add_alg(), 'exact' wants to be
 initialized to 0

We declare 'exact' without initializing it and then do:

[...]
	if (strlen(p->cru_driver_name))
		exact = 1;

	if (priority && !exact)
		return -EINVAL;

[...]

If the first 'if' is not true, then the second will test an
uninitialized 'exact'.
As far as I can tell, what we want is for 'exact' to be initialized to
0 (zero/false).

Subject: [PATCH 1149/6423] net/hyperv: Correct the assignment in
 netvsc_recv_callback()

The first assignment to variable "net" is wrong, but overridden by the
latter assignments. So the bug isn't manifested.

Subject: [PATCH 1155/6423] bnx2: Add missing memory barrier in
 bnx2_start_xmit()

Sync DMA descriptor before hitting the TX mailbox for weak memory model
CPUs.

There has been discussions several years ago about this.  Some believe
that writel() should guarantee ordering.  Others want explicit barriers
if necessary.  Today writel() does not have the ordering guarantee and
many other drivers use explicit barriers.

Subject: [PATCH 1157/6423] usb: dwc3: gadget: re-factor USB2 test mode to a
 function

There are some situations were we might need to
enable USB Test Modes without having access to a
Host stack. In such situations we cannot rely
solely on USB Control Messages to enable test
features.

For those cases, we will also allow test mode
to be enabled via debugfs and this patch is a
preparation for that.

Subject: [PATCH 1159/6423] usb: dwc3: gadget: re-factor Link state change to a
 function

Most link changes will, of course, happen with
the help of a matching host HW, but in some cases
we might want to debug very low level details about
the link and exposing this to debugfs sounds like
a good plan.

This is a preparation for such setup.

Only bit 3 of the event status bitfield is valid
and the others should not be considered.

Make sure SW matches documentation on that case
to avoid bogus debugging prints which would
confuse an engineer.

We hold that pointer for one reason. It just

Subject: [PATCH 1164/6423] usb: dwc3: gadget: dynamically re-size TxFifos

We need to dynamically re-size TxFifos for the
cases where default values will not do.

While at that, we create a simple function which,
for now, will just allocate one full packet fifo
space for each of the enabled endpoints.

This can be improved later in order to allow for
better throughput by allocating more space for
endpoints which could make good use of that like
isochronous and bulk.

We're only using the 4 byte events and memcpy()
will make us slower. We can easily avoid that.

Subject: [PATCH 1170/6423] HID: multitouch: add support for trackpads

* some multitouch trackpads present the touch usage. This needs to be
filtered as it will conflict with mt-implementation.
* trackpads send BTN_TOOL_* to notify how many fingers are present
(this is used by xorg to use synaptics instead of generic evdev)
* trackpads like Perixx 701 are not different from a hid point of view
from a touchscreen, and we need to manually set them as touchpad.

Subject: [PATCH 1171/6423] HID: multitouch: add control of the feature
 "Maximum Contact Number"

Some devices, like Perixx Peripad 701 do not work if the feature
"Maximum Contact Number" is not set to the right value.
This patch allows hid-multitouch to control this feature.

If the programmer fills the field maxcontacts in the mt_class,
then the driver will set the feature to this value. It is safe
for current drivers as the feature is read/write in the HID norm
and all devices should implement the norm.

Subject: [PATCH 1172/6423] HID: multitouch: support Perixx PERIPAD 701

Perixx Peripad 701 is an hybrid device which presents a touchpad and
a keyboard on the same surface. The switch between the two is controlled
by a physical switch, and the firmware sends the events on the right
interface (mouse, keyboard or multitouch).
This patch enables the multitouch interface of this device to work.

We need to manually set the device as a trackpad (we cannot infer it
from the reports descriptors as the device works under Windows, a system
that does not allow multitouch touchpad).
We also need to set the hid feature MAX CONTACT NUMBER to 2 or the device
stops sending events once it has been pressed by two touches.

Subject: [PATCH 1178/6423] SUNRPC: Adding status trace points

This patch adds three trace points to the status routines
in the sunrpc state machine.

The goal of these trace points is to give an Admin
the ability to check on binding status or connection
status to see if there is a potential problem.

Subject: [PATCH 1179/6423] ASoC: dapm: Export mixer|mux_update_power() to
 public API.

Allow for the operation of custom mixer and mux DAPM widgets that can call
snd_soc_dapm_mixer_update_power() and snd_soc_dapm_mux_update_power() directly
after updating their status. This is useful with complex DAPM Mixer operations
where we need to do additional work in addition to setting a few mixer register
bits.

Subject: [PATCH 1180/6423] HID: add support for tivo slide remote

This patch finishes off adding full support for the TiVo Slide remote,
which is a mostly pure HID device from the perspective of the kernel.
There are a few mappings that use a vendor-specific usage page, and a
few keys in the consumer usage page that I think make sense to remap
slightly, to better fit their key labels' intended use. Doing this in a
stand-alone hid-tivo.c makes the modifications only matter for this
specific device.

What's actually connected to the computer is a Broadcom-made usb dongle,
which has an embedded hub, bluetooth adapter, mouse and keyboard
devices. You pair with the dongle, then the remote sends data that its
converted into HID on the keyboard interface (the mouse interface
doesn't do anything interesting, so far as I can tell).

lsusb for this device:
Bus 004 Device 005: ID 0a5c:2190 Broadcom Corp.
Bus 004 Device 004: ID 0a5c:4503 Broadcom Corp.
Bus 004 Device 003: ID 150a:1201
Bus 004 Device 002: ID 0a5c:4500 Broadcom Corp. BCM2046B1 USB 2.0 Hub (part of BCM2046 Bluetooth)

Speaking of the keyboard interface, the remote actually does contain a
keyboard as well. The top slides away, revealing a reasonably functional
qwerty keyboard (not unlike many slide cell phones), thus the product
name.

Subject: [PATCH 1190/6423] ASoC: wm8994: We don't need to runtime resume by

This is the default state that the runtime PM infrastructure expects so
instead just kick the runtime PM core to suspend us if we're not doing
anything (as is default).

Otherwise we might get an error if the GPIO is configured as an input
since that makes the register volatile and a suspended device can't be
read from.

Subject: [PATCH 1192/6423] ASoC: wm8994: Bring WM8994 accessory detection up
 to date

Make the mechanism used for WM8994 more like that for WM1811 and WM8958:
provide the logic to distinguish between headphone and headset and hard
code the reporting of sensible SND_JACK values. Should integration with
other detection mechanisms be required we can add appropriate callbacks
(though some integrations should be able to use the subsystem ones).

Subject: [PATCH 1193/6423] regmap: Don't use bitfields for booleans

This was a cut'n'paste from some older code.

Since we're about to add debugfs support don't do the obvious thing and
use bool, use u32 instead (which debugfs has been using since time
immemorial).

Subject: [PATCH 1195/6423] mac80211: move managed mode station state
 modification

Move the station state modification right before insert,
this just makes the current code more readable (you can
tell that it's before insertion looking at a single
screenful of code) right now, but some upcoming changes
will require this.

Subject: [PATCH 1196/6423] mac80211: simplify AP_VLAN handling

Setting keys and updating TKIP keys must use the
BSS sdata (not AP_VLAN), so we translate. Move
the translation into driver-ops wrappers instead
of having it inline in the code to simplify the
normal code flow.

The same can be done for sta_add/remove which
already does the translation in the wrapper.

Subject: [PATCH 1197/6423] mac80211: dont program keys for stations not
 uploaded

If a station couldn't be uploaded to the driver but
is still kept (only in IBSS mode) we still shouldn't
try to program the keys for it into hardware; fix
this bug by skipping the key upload in this case.

Subject: [PATCH 1199/6423] mac80211: add sta_state callback

(based on Eliad's patch)

Add a callback to notify the low-level driver whenever
the state of a station changes. The driver is only
notified when the station is actually in the mac80211
hash table, not for pre-insert state transitions.

To allow the driver to replace sta_add/remove calls
with this, call extra transitions with the NOTEXIST
state.

This callback can fail, so we need to be careful in
handling it when a station is inserted, particularly
in the IBSS case where we still keep the station entry
around for mac80211 purposes.

Subject: [PATCH 1200/6423] mac80211: implement sta_add/sta_remove in sta_state

Instead of maintaining separate sta_add/sta_remove
callsites, implement it in sta_state when the driver
has no sta_state implementation.

The only behavioural change this should cause is in
secure mesh mode: with this the station entries will
only be created after the stations are set to AUTH.
Given which drivers support mesh, this seems to not
be a problem.

Subject: [PATCH 1201/6423] mac80211: remove dummy STA support

The dummy STA support was added because I didn't
want to change the driver API at the time. Now
that we have state transitions triggering station
add/remove in the driver, we only call add once a
station reaches ASSOCIATED, so we can remove the
dummy station stuff again.

While at it, tighten the RX check and accept only
port control (EAP) frames from the AP station if
it's not associated yet -- in other cases there's
no race.

From 95de817b9034d50860319f6033ec85d25024694c Mon Sep 17 00:00:00 2001

Subject: [PATCH 1202/6423] cfg80211: stop tracking authenticated state

To track authenticated state seems to have been
a design mistake in cfg80211. It is possible to
have out of band authentication (FT), tracking
multiple authentications caused more problems
than it ever helped, and the implementation in
mac80211 is too complex.

Remove all this complexity, and let userspace
do whatever it wants to, mac80211 can deal with
that just fine. Association is still tracked of
course, but authentication no longer is. Local
auth state changes are thus no longer of value,
so ignore them completely.

This will also help implement SAE -- asking the
driver to do an authentication is now almost
equivalent to sending an authentication frame,
with the exception of shared key authentication
which is still handled completely.

Subject: [PATCH 1203/6423] cfg80211: export cfg80211_ref_bss

This is needed by mac80211 to keep a reference
to a BSS alive for the auth process. Remove the
old version of cfg80211_ref_bss() since it's
not actually used.

Subject: [PATCH 1204/6423] mac80211: redesign auth/assoc

This is the second part of the auth/assoc redesign,
the mac80211 part. This moves the auth/assoc code
out of the work abstraction and into the MLME, so
that we don't flip channels all the time etc.

The only downside is that when we are associated,
we need to drop the association in order to create
a connection to another AP, but for most drivers
this is actually desirable and the ability to do
was never used by any applications. If we want to
implement resource reservation with FT-OTA, we'd
probably best do it with explicit R-O-C in wpa_s.

Subject: [PATCH 1214/6423] bcma: make some functions __devinit

bcma_core_pci_hostmode_init() has to be in __devinit as it will call a
function in that section and so all functions calling it also have to
be in __devinit.

Subject: [PATCH 1215/6423] bcma: add PCIe host controller

Some SoCs have a PCIe host controller to make it possible to attach
some other devices to it, like an other Wifi card.
This code was tested with an Netgear WNDR3400 (bcm4716 based), but
should work with all bcma based SoCs.

This patch fixes the problem by deriving "priv" from wiphy
when net_device pointer is NULL.

Subject: [PATCH 1231/6423] mac80211: support hw scan while idle

Currently, mac80211 goes to idle-off before starting a scan.
However, some devices that implement hw scan might not
need going idle-off in order to perform a hw scan, and
thus saving some energy and simplifying their state machine.

(Note that this is also the case for sched scan - it
currently doesn't make mac80211 go idle-off)

Add a new flag to indicate support for hw scan while idle.

Memory allocated by ieee80211_alloc_hw() will get orphaned
if any subsequent initializations fail.

Also don't pci_set_drvdata(pdev, NULL) until just before disabling
the PCI device. Functions called by rtl_deinit_core(hw) may eventually need
the context (when its actually implemented).

Subject: [PATCH 1234/6423] mwifiex: update correct dtim_period in
 dump_station()

Earlier we were using dtim period extracted from scan response
buffer provided by FW in scan operation. But it is observed that
sometimes the buffer doesn't contain dtim period tlv, and wrong
value (0) was sent to user space.

After association FW will start listening to beacon frames of
connected AP and store dtim period. Therefore we can get it from
FW in dump_station() instead of using wrong value obtained in
scanning.

Redundant code after adapting new approach for dtim period is
also removed in this patch.

From 1023f3bc7b3f56da1f79f605cbe459318c4792ae Mon Sep 17 00:00:00 2001
From: Stanislaw Gruszka <sgruszka@redhat.com>
Date: Fri, 3 Feb 2012 17:32:01 +0100
Subject: [PATCH 1259/6423] iwlegacy: remove set_hw_params callback

We do not need that callback, settings parameters can be done locally.

Subject: [PATCH 1260/6423] net: Make qdisc_skb_cb upper size bound explicit.

Just like skb->cb[], so that qdisc_skb_cb can be encapsulated inside
of other data structures.

This is intended to be used by IPoIB so that it can remember
addressing information stored at hard_header_ops->create() time that
it can fetch when the packet gets to the transmit routine.

Subject: [PATCH 1261/6423] mac80211: call rate control only after init

There are situations where we don't have the
necessary rate control information yet for
station entries, e.g. when associating. This
currently doesn't really happen due to the
dummy station handling; explicitly disabling
rate control when it's not initialised will
allow us to remove dummy stations.

Subject: [PATCH 1263/6423] tipc: Prevent transmission of outdated link
 protocol messages

Ensures that a link endpoint discards any previously deferred link
protocol message whenever it attempts to send a new one.

Previously, it was possible for a link protocol message that was unsent
due to congestion to be transmitted after newer protocol messages had
been sent. The stale link protocol message might then cause the receiving
link endpoint to malfunction because of its outdated conent.

Thanks to Osamu Kaminuma [okaminum@avaya.com] for diagnosing the problem
and contributing a prototype patch.

Subject: [PATCH 1264/6423] tipc: Prevent broadcast link stalling in dual LAN
 environments

Ensure that sequence number information about incoming broadcast link
messages is initialized only by the activation of the first link to a
given cluster node.  Previously, a race condition allowed reset and/or
activation messages for a second link to re-initialize this sequence
number information with obsolete values. This could trigger TIPC to
request the retransmission of previously acknowledged broadcast link
messages from that node, resulting in broadcast link processing becoming
stalled if the node had already released one or more of those messages
and was unable to perform the required retransmission.

Thanks to Laser <gotolaser@gmail.com> for identifying this problem
and assisting in the development of this fix.

Subject: [PATCH 1265/6423] tipc: Ensure broadcast link re-acquires node after
 link failure

Fix a bug that can prevent TIPC from sending broadcast messages to a node
if contact with the node is lost and then regained. The problem occurs if
the broadcast link first clears the flag indicating the node is part of the
link's distribution set (when it loses contact with the node), and later
fails to restore the flag (when contact is regained); restoration fails
if contact with the node is regained by implicit unicast link activation
triggered by the arrival of a data message, rather than explicitly by the
arrival of a link activation message.

The broadcast link now uses separate fields to track whether a node is
theoretically capable of receiving broadcast messages versus whether it is
actually part of the link's distribution set. The former member is updated
by the receipt of link protocol messages, which can occur at any time; the
latter member is updated only when contact with the node is gained or lost.
This change also permits the simplification of several conditional
expressions since the broadcast link's "supported" field can now only be
set if there are working links to the associated node.

Subject: [PATCH 1266/6423] tipc: Fix problem with broadcast link
 synchronization between nodes

Corrects a problem in which a link endpoint that activates as the
result of receiving a RESET/STATE sequence of link protocol messages
fails to properly record the broadcast link status information about
the node to which it is now communicating with. (The problem does
not occur with the more common RESET/ACTIVATE sequence of messages.)
The fix ensures that the broadcast link status info is updated after
the RESET message resets the link endpoint, rather than before, thereby
preventing new information from being overwritten by the reset operation.

Subject: [PATCH 1268/6423] tipc: Fix node lock reclamation issues in broadcast
 link reception

Fixes a pair of problems in broadcast link message reception code
relating to the reclamation of the node lock after consuming an
in-sequence message.

1) Now retests to see if the sending node is still up after reclaiming
   the node lock, and bails out if it is non-operational.

2) Now manipulates the node's deferred message queue only after
   reclaiming the node lock, rather than using queue head pointer
   information that was cached previously.

Subject: [PATCH 1271/6423] tipc: Major redesign of broadcast link ACK/NACK
 algorithms

Completely redesigns broadcast link ACK and NACK mechanisms to prevent
spurious retransmit requests in dual LAN networks, and to prevent the
broadcast link from stalling due to the failure of a receiving node to
acknowledge receiving a broadcast message or request its retransmission.

Note: These changes only impact the timing of when ACK and NACK messages
are sent, and not the basic broadcast link protocol itself, so inter-
operability with nodes using the "classic" algorithms is maintained.

The revised algorithms are as follows:

1) An explicit ACK message is still sent after receiving 16 in-sequence
messages, and implicit ACK information continues to be carried in other
unicast link message headers (including link state messages).  However,
the timing of explicit ACKs is now based on the receiving node's absolute
network address rather than its relative network address to ensure that
the failure of another node does not delay the ACK beyond its 16 message
target.

2) A NACK message is now typically sent only when a message gap persists
for two consecutive incoming link state messages; this ensures that a
suspected gap is not confirmed until both LANs in a dual LAN network have
had an opportunity to deliver the message, thereby preventing spurious NACKs.
A NACK message can also be generated by the arrival of a single link state
message, if the deferred queue is so big that the current message gap
cannot be the result of "normal" mis-ordering due to the use of dual LANs
(or one LAN using a bonded interface). Since link state messages typically
arrive at different nodes at different times the problem of multiple nodes
issuing identical NACKs simultaneously is inherently avoided.

3) Nodes continue to "peek" at NACK messages sent by other nodes. If
another node requests retransmission of a message gap suspected (but not
yet confirmed) by the peeking node, the peeking node forgets about the
gap and does not generate a duplicate retransmit request. (If the peeking
node subsequently fails to receive the lost message, later link state
messages will cause it to rediscover and confirm the gap and send another
NACK.)

4) Message gap "equality" is now determined by the start of the gap only.
This is sufficient to deal with the most common cases of message loss,
and eliminates the need for complex end of gap computations.

5) A peeking node no longer tries to determine whether it should send a
complementary NACK, since the most common cases of message loss don't
require it to be sent. Consequently, the node no longer examines the
"broadcast tag" field of a NACK message when peeking.

Subject: [PATCH 1273/6423] tipc: Prevent loss of fragmented messages over
 unicast links

Modifies unicast link endpoint logic so an incoming fragmented message
is not lost if reassembly cannot begin because there is no buffer big
enough to hold the entire reassembled message. The link endpoint now
ignores the first fragment completely, which causes the sending node to
retransmit the first fragment so that reassembly can be re-attempted.

Previously, the sender would have had no reason to retransmit the 1st
fragment, so we would never have a chance to re-try the allocation.

Subject: [PATCH 1274/6423] tipc: Prevent loss of fragmented messages over
 broadcast link

Modifies broadcast link so that an incoming fragmented message is not
lost if reassembly cannot begin because there currently is no buffer
big enough to hold the entire reassembled message. The broadcast link
now ignores the first fragment completely, which causes the sending node
to retransmit the first fragment so that reassembly can be re-attempted.

Previously, the sender would have had no reason to retransmit the 1st
fragment, so we would never have a chance to re-try the allocation.

To do this cleanly without duplicaton, a new bclink_accept_pkt()
function is introduced.

Subject: [PATCH 1275/6423] tipc: Eliminate alteration of publication key
 during name table purging

Removes code that alters the publication key of a name table entry
that is being forcibly purged from TIPC's name table after contact
with the publishing node has been lost.

Current TIPC ensures that all defunct names are purged before
re-establishing contact with a failed node.  There used to be a risk
that the publication might be accidentally deleted because it might be
re-added to the name table before the purge operation was completed.
But now there is no longer a need to ensure that the new key is different
than the old one.

Subject: [PATCH 1277/6423] SUNRPC: Change the default limit to the number of
 TCP slots

Since the scheme of limiting the number of TCP slots to whatever will
fit in the current TCP window seems to be working well (Andy reports
getting within 20% of the 'iperf' send performance on a 10GigE link)
we should just let that be the default mode of operation.

Users may still set their own limits using the tcp_max_slot_table_entries
parameter if they need to.

Subject: [PATCH 1279/6423] NFS: Call test_stateid() and free_stateid() with
 correct stateids

I noticed that test_stateid() was always using the same stateid for open
and lock recovery.  After poking around a bit, I discovered that it was
always testing with a delegation stateid (even if there was no
delegation present).  I figured this wasn't correct, so now delegation
and open stateids are tested during open_expired() and lock stateids are
tested during lock_expired().

We check "task->tk_rqstp" and then we dereference it without checking on
the next line.  The only caller is call_connect() and that has a check
which prevents it from calling xprt_connect() with a NULL.

                if (task->tk_status < 0)
                        return;

If "task->tk_rqstp" were NULL then "tk_status" would be -EAGAIN.

From a030889a01d1bea921e1a7501010b7b891d2abd2 Mon Sep 17 00:00:00 2001
From: Weston Andros Adamson <dros@netapp.com>
Date: Thu, 26 Jan 2012 13:32:23 -0500
Subject: [PATCH 1282/6423] NFS: start printks w/ NFS: even if __func__ shown

This patch addresses printks that have some context to show that they are
from fs/nfs/, but for the sake of consistency now start with NFS:

From 2d3fe01c36a9b881fae89c5bdf4085a4d7d53ae1 Mon Sep 17 00:00:00 2001
From: Weston Andros Adamson <dros@netapp.com>
Date: Fri, 3 Feb 2012 15:45:40 -0500
Subject: [PATCH 1283/6423] NFS: Fix comparison between DS address lists

data_server_cache entries should only be treated as the same if the address
list hasn't changed.

A new entry will be made when an MDS changes an address list (as seen by
GETDEVINFO). The old entry will be freed once all references are gone.

Subject: [PATCH 1284/6423] NFS: Fall back on old idmapper if request_key()
 fails

This patch removes the CONFIG_NFS_USE_NEW_IDMAPPER compile option.
First, the idmapper will attempt to map the id using /sbin/request-key
and nfsidmap.  If this fails (if /etc/request-key.conf is not configured
properly) then the idmapper will call the legacy code to perform the
mapping.  I left a comment stating where the legacy code begins to make
it easier for somebody to remove in the future.

+or by placing a call to the rpc.idmap daemon.
+
+NFS will attempt to call /sbin/request-key first.  If this succeeds, the

+only fail if /etc/request-key.conf is not configured for the id_resolver key
+type, see the "Configuring" section below if you wish to use the request-key
+method.
+
+If the call to /sbin/request-key fails (if /etc/request-key.conf is not
+configured with the id_resolver key type), then the idmapper will ask the
+legacy rpc.idmap daemon for the id mapping.  This result will be stored
+in a custom NFS idmap cache.

Subject: [PATCH 1287/6423] NFS: make nfs_client_list per net ns

This patch splits global list of NFS clients into per-net-ns array of lists.
This looks more strict and clearer.
BTW, this patch also makes "/proc/fs/nfsfs/servers" entry content depends on
/proc mount owner pid namespace. See below for details.

NOTE: few words about how was /proc/fs/nfsfs/ entries content show per network
namespace done. This is a little bit tricky and not the best is could be. But
it's cheap (proper fix for /proc conteinerization is a hard nut to crack).
The idea is simple: take proper network namespace from pid namespace
child reaper nsproxy of /proc/ mount creator.
This actually means, that if there are 2 containers with different net
namespace sharing pid namespace, then read of /proc/fs/nfsfs/ entries will
always return content, taken from net namespace of pid namespace creator task
(and thus second namespace set wil be unvisible).

Subject: [PATCH 1288/6423] NFS: make nfs_volume_list per net ns

This patch splits global list of NFS servers into per-net-ns array of lists.
This looks more strict and clearer.
BTW, this patch also makes "/proc/fs/nfsfs/volumes" content depends on /proc
mount owner pid namespace. See below for details.

NOTE: few words about how was /proc/fs/nfsfs/ entries content show per network
namespace done. This is a little bit tricky and not the best is could be. But
it's cheap (proper fix for /proc conteinerization is a hard nut to crack).
The idea is simple: take proper network namespace from pid namespace
child reaper nsproxy of /proc/ mount creator.
This actually means, that if there are 2 containers with different net
namespace sharing pid namespace, then read of /proc/fs/nfsfs/ entries will
always return content, taken from net namespace of pid namespace creator task
(and thus second namespace set wil be unvisible).

Subject: [PATCH 1289/6423] NFS: make cb_ident_idr per net ns

This patch makes ID's infrastructure network namespace aware. This was done
mainly because of nfs_client_lock, which is desired to be per network
namespace, but protects NFS clients ID's.

NOTE: NFS client's net pointer have to be set prior to ID initialization,
proper assignment was moved.

Subject: [PATCH 1296/6423] x86/spinlocks: Eliminate TICKET_MASK

The definition of it being questionable already (unnecessarily
including a cast), and it being used in a single place that can
be written shorter without it, remove this #define.

Along the same lines, simplify __ticket_spin_is_locked()'s main
expression, which was the more convoluted way because of needs
that went away with the recent type changes by Jeremy.

This is pure cleanup, no functional change intended.

Subject: [PATCH 1298/6423] igbvf: refactor Interrupt Throttle Rate code

The existing ITR code is broken and confusing, with lots of similarly-named
variables that do different things. Additionally, after the driver carefully
determines the optimal interrupt rate for the adapter, it then
ignores it and always writes a fixed, suboptimal value.

This patch refactors that code to make variable names more descriptive of
what they actually do, and then actually writes the calculated result to
the hardware.

Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps
to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.

Date: Tue, 31 Jan 2012 06:37:27 +0000
Subject: [PATCH 1301/6423] e1000e: cleanup - check return values consistently

The majority of the e1000e code checks most function return values using a
test like 'if (ret_val)' or 'if (!ret_val)' but there are a few instances
of 'if (ret_val == 0)'.  This patch converts the latter to the former for
consistency.

Combine two switch statements into one, convert a nebulous pointer to one
that is a bit more in keeping with the rest of the driver code and remove
some dead code (there are no 80003es2lan devices with fiber).  No change in
functionality, just cosmetic changes.

Subject: [PATCH 1310/6423] net/sched: sch_plug - Queue traffic until an
 explicit release command

The qdisc supports two operations - plug and unplug. When the
qdisc receives a plug command via netlink request, packets arriving
henceforth are buffered until a corresponding unplug command is received.
Depending on the type of unplug command, the queue can be unplugged
indefinitely or selectively.

This qdisc can be used to implement output buffering, an essential
functionality required for consistent recovery in checkpoint based
fault-tolerance systems. Output buffering enables speculative execution
by allowing generated network traffic to be rolled back. It is used to
provide network protection for Xen Guests in the Remus high availability
project, available as part of Xen.

This module is generic enough to be used by any other system that wishes
to add speculative execution and output buffering to its applications.

This module was originally available in the linux 2.6.32 PV-OPS tree,
used as dom0 for Xen.

For more information, please refer to http://nss.cs.ubc.ca/remus/
and http://wiki.xensource.com/xenwiki/Remus

Changes in V3:
  * Removed debug output (printk) on queue overflow
  * Added TCQ_PLUG_RELEASE_INDEFINITE - that allows the user to
    use this qdisc, for simple plug/unplug operations.
  * Use of packet counts instead of pointers to keep track of
    the buffers in the queue.

+	  This queuing discipline allows userspace to plug/unplug a network

+	  packet flow.
+
+	  This module also provides a generic "network output buffering"
+	  functionality (aka output commit), wherein upon arrival of a dequeue

+ * There are two ways to use this qdisc:
+ * 1. A simple "instantaneous" plug/unplug operation, by issuing an alternating
+ *    sequence of TCQ_PLUG_BUFFER & TCQ_PLUG_RELEASE_INDEFINITE commands.
+ *
+ * 2. For network output buffering (a.k.a output commit) functionality.
+ *    Output commit property is commonly used by applications using checkpoint
+ *    based fault-tolerance to ensure that the checkpoint from which a system
+ *    is being restored is consistent w.r.t outside world.
+ *
+ *    Consider for e.g. Remus - a Virtual Machine checkpointing system,
+ *    wherein a VM is checkpointed, say every 50ms. The checkpoint is replicated
+ *    asynchronously to the backup host, while the VM continues executing the
+ *    next epoch speculatively.
+ *
+ *    The following is a typical sequence of output buffer operations:
+ *       1.At epoch i, start_buffer(i)
+ *       2. At end of epoch i (i.e. after 50ms):
+ *          2.1 Stop VM and take checkpoint(i).
+ *          2.2 start_buffer(i+1) and Resume VM
+ *       3. While speculatively executing epoch(i+1), asynchronously replicate
+ *          checkpoint(i) to backup host.
+ *       4. When checkpoint_ack(i) is received from backup, release_buffer(i)
+ *    Thus, this Qdisc would receive the following sequence of commands:
+ *       TCQ_PLUG_BUFFER (epoch i)
+ *       .. TCQ_PLUG_BUFFER (epoch i+1)

Subject: [PATCH 1311/6423] net: fec: Fix build due to wrong dev annotation

commit 21a4e469 (netdev: ethernet dev_alloc_skb to netdev_alloc_skb)
should have used "ndev" instead of "dev".

This causes the following build errors:

drivers/net/ethernet/freescale/fec.c: In function 'fec_enet_rx':
drivers/net/ethernet/freescale/fec.c:714: error: 'dev' undeclared (first use in this function)
drivers/net/ethernet/freescale/fec.c:714: error: (Each undeclared identifier is reported only once
drivers/net/ethernet/freescale/fec.c:714: error: for each function it appears in.)
drivers/net/ethernet/freescale/fec.c: In function 'fec_enet_alloc_buffers':
drivers/net/ethernet/freescale/fec.c:1213: error: 'dev' undeclared (first use in this function)

Fix it, so that fec driver can be built again.

Subject: [PATCH 1312/6423] sh-eth: use netdev stats structure and fix
 dma_map_single

No need to maintain a parallel net_device_stats structure in
sh_eth_private, since we have a generic one in netdev

Fix two dma_map_single() incorrect parameters, passing skb->tail instead
of skb->data. Seems that there is no corresponding dmap_unmap_single()
calls for the moment in this driver.

Subject: [PATCH 1319/6423] ath6kl: store firmware logs in skbuffs

Currently firmware logs are stored in a circular buffer, but this was
not very flexible and fragile. It's a lot easier to store logs to struct
skbuffs and store them in a skb queue. Also this makes it possible
to easily increase the buffer size, even dynamically if we so want (but
that's not yet supported).

From user space point of view nothing should change.

Subject: [PATCH 1320/6423] ath6kl: add blocking debugfs file for retrieving
 firmware logs

When debugging firmware issues it's not always enough to get
the latest firmware logs, sometimes we need to get logs from a longer
period. To make this possible, add a debugfs file named fwlog_block. When
reading from this file ath6kl will send firmware logs whenever available
and otherwise it will block and wait for new logs.

Subject: [PATCH 1322/6423] ath6kl: prioritize Tx bundling based on AC
 priorities

Tx bundling is the more efficient use of SDIO bus and allows more packet
transfers with fewer bus transactions, and is a way to improve overall
throughput. However, Tx bundling has only 4 scatter request resources available.
When there are multiple traffic streams of different priorities, it's possible
that lower priority traffic may hog all the scatter requests and lock out the
higher prioirty traffic from bundling.
Tx bundling is now enabled per AC. When an AC do a scatter request and
the remaining scatter request resources is lower than a configurable
threshold, it will disable Tx bundling for all AC's of lower priorities.
When an AC has Tx bundling disabled and has no Tx bundles sent in a
consecutive and configurable number of packets, Tx bundling will be re-enabled
for that AC.

Subject: [PATCH 1332/6423] [media] tm6000: Don't use pointer after freeing it
 in tm6000_ir_fini()

In tm6000_ir_fini() there seems to be a problem.
rc_unregister_device(ir->rc); calls rc_free_device() on the pointer it is
given, which frees it.

Subsequently the function does:

  if (!ir->polling)
    __tm6000_ir_int_stop(ir->rc);

and __tm6000_ir_int_stop() dereferences the pointer it is given, which
has already been freed.

and it also does:

  tm6000_ir_stop(ir->rc);

which also dereferences the (already freed) pointer.

So, it seems that the call to rc_unregister_device() should be move
below the calls to __tm6000_ir_int_stop() and tm6000_ir_stop(), so
those don't operate on a already freed pointer.

But, I must admit that I don't know this code *at all*, so someone who
knows the code should take a careful look before applying this
patch. It is based purely on inspection of facts of what is beeing
freed where and not at all on understanding what the code does or why.
I don't even have a means to test it, so beyond testing that the
change compiles it has seen no testing what-so-ever.

Anyway, here's a proposed patch.

 easycap_usb_probe()

If allocating 'pdata_urb' fails, the function will return -ENOMEM
without freeing the memory allocated, just a few lines above, for
'purb' and will leak that memory when 'purb' goes out of scope.

This patch resolves the leak by freeing the allocated storage with
usb_free_urb() before the return.

The two orinoco mailing lists on sourceforge were set up many years

I don't have to keep filtering the spam from them (which is most of
what comes through now).  In preparation, this patch removes the
reference to them from the MAINTAINERS file.  Any remaining discussion
of this approaching obsolete driver can go to the linux-wireless list.

We are getting more and more fields in struct rt2x00_dev that are
specific to one or two of the low-level drivers. Instead of putting
these fields inside the main structure and thus clobbering all low-level
drivers with these fields, introduce the concept of driver data inside
struct rt2x00_dev, whose size is indicated by the low-level driver and
which can be populated by the low-level driver.

Subject: [PATCH 1340/6423] rt2x00: Update comment on freq_offset field in
 struct rt2x00_dev.

The comment states that the field is only used for rt61pci and rt73usb.
However, it is now used by rt2800pci and rt2800usb as well, so the
comment is not correct anymore.

Update the comment to not state any low-level drivers anymore.

Subject: [PATCH 1348/6423] mac80211: rename mesh static path_lookup()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If you want to use mesh support from mac80211 on a recent
kernel on 2.6.24 you'll run into a name clash when compiling
against include/linux/namei.h, so rename this routine.

/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c: At top level:
/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c:342:26: error: conflicting types for ‘path_lookup’
include/linux/namei.h:71:12: note: previous declaration of ‘path_lookup’ was here

Although this could sit as a separate patch in compat-wireless it seems
best to just merge upstream.

Subject: [PATCH 1350/6423] IPoIB: Stop lying about hard_header_len and use
 skb->cb to stash LL addresses

Commit a0417fa3a18a ("net: Make qdisc_skb_cb upper size bound
explicit.") made it possible for a netdev driver to use skb->cb
between its header_ops.create method and its .ndo_start_xmit
method.  Use this in ipoib_hard_header() to stash away the LL address
(GID + QPN), instead of the "ipoib_pseudoheader" hack.  This allows
IPoIB to stop lying about its hard_header_len, which will let us fix
the L2 check for GRO.

Subject: [PATCH 1351/6423] gro: more generic L2 header check

Shlomo Pongratz reported GRO L2 header check was suited for Ethernet
only, and failed on IB/ipoib traffic.

He provided a patch faking a zeroed header to let GRO aggregates frames.

Roland Dreier, Herbert Xu, and others suggested we change GRO L2 header
check to be more generic, ie not assuming L2 header is 14 bytes, but
taking into account hard_header_len.

__napi_gro_receive() has special handling for the common case (Ethernet)
to avoid a memcmp() call and use an inline optimized function instead.

Subject: [PATCH 1352/6423] ipv4: Implement IP_UNICAST_IF socket option.

The IP_UNICAST_IF feature is needed by the Wine project.  This patch
implements the feature by setting the outgoing interface in a similar
fashion to that of IP_MULTICAST_IF.  A separate option is needed to
handle this feature since the existing options do not provide all of
the characteristics required by IP_UNICAST_IF, a summary is provided
below.

SO_BINDTODEVICE:
* SO_BINDTODEVICE requires administrative privileges, IP_UNICAST_IF
does not.  From reading some old mailing list articles my
understanding is that SO_BINDTODEVICE requires administrative
privileges because it can override the administrator's routing
settings.
* The SO_BINDTODEVICE option restricts both outbound and inbound
traffic, IP_UNICAST_IF only impacts outbound traffic.

IP_PKTINFO:
* Since IP_PKTINFO and IP_UNICAST_IF are independent options,
implementing IP_UNICAST_IF with IP_PKTINFO will likely break some
applications.
* Implementing IP_UNICAST_IF on top of IP_PKTINFO significantly
complicates the Wine codebase and reduces the socket performance
(doing this requires a lot of extra communication between the
"server" and "user" layers).

bind():
* bind() does not work on broadcast packets, IP_UNICAST_IF is
specifically intended to work with broadcast packets.
* Like SO_BINDTODEVICE, bind() restricts both outbound and inbound
traffic.

Subject: [PATCH 1356/6423] drm/i915: swizzling support for snb/ivb

We have to do this manually. Somebody had a Great Idea.

I've measured speed-ups just a few percent above the noise level
(below 5% for the best case), but no slowdows. Chris Wilson measured
quite a bit more (10-20% above the usual snb variance) on a more
recent and better tuned version of sna, but also recorded a few
slow-downs on benchmarks know for uglier amounts of snb-induced
variance.

v2: Incorporate Ben Widawsky's preliminary review comments and
elaborate a bit about the performance impact in the changelog.

v3: Add a comment as to why we don't need to check the 3rd memory
channel.

v4: Fixup whitespace.

Subject: [PATCH 1357/6423] drm/i915: consolidate swizzling control bit
 frobbing

On gen5 we also need to correctly set up swizzling in the display
scanout engine, but only there. Consolidate this into the same
function.

This has a small effect on ums setups - the kernel now also sets this
bit in addition to userspace setting it. Given that this code only
runs when userspace either can't (resume, gpu reset) or explicitly
won't(gem_init) touch the hw this shouldn't have an adverse effect.

Subject: [PATCH 1359/6423] [IA64] disable interrupts when exiting from
 ia64_mca_cmc_int_handler()

SAL specification mandates that ia64_mca_log_sal_error_record() gets
called with interrupts enabled, and that's why ia64_mca_cmc_int_handler()
is enabling them. It however forgets to re-disable them when exiting,
which triggers WARN_ON() in generic IRQ handler.

Disable the interrupts again before exiting. This is analogous to
a3967685745 ("[IA64] disable interrupts at end of ia64_mca_cpe_int_handler()").

From 1ab0d2ec9aeb4489c05158e8a2b00bad89f67e03 Mon Sep 17 00:00:00 2001
From: "Pradeep A. Dalvi" <netdev@pradeepdalvi.com>
Date: Mon, 6 Feb 2012 11:16:48 +0000
Subject: [PATCH 1361/6423] netdev: ethernet dev_alloc_skb to netdev_alloc_skb

Replaced deprecating dev_alloc_skb with netdev_alloc_skb in drivers/net/ethernet
  - Removed extra skb->dev = dev after netdev_alloc_skb

Subject: [PATCH 1362/6423] af_iucv: remove IUCV-pathes completely

A SEVER is missing in the callback of a receiving SEVERED. This may
inhibit z/VM to remove the corresponding IUCV-path completely.
This patch adds a SEVER in iucv_callback_connrej (together with
additional locking.

Subject: [PATCH 1364/6423] af_iucv: change net_device handling for HS
 transport

This patch saves the net_device in the iucv_sock structure during
bind in order to fasten skb sending.
In addition some other small improvements are made for HS transport:
   - error checking when sending skbs
   - locking changes in afiucv_hs_callback_txnotify
   - skb freeing in afiucv_hs_callback_txnotify
And finally it contains code cleanup to get rid of iucv_skb_queue_purge.

Subject: [PATCH 1365/6423] af_iucv: allow retrieval of maximum message size

For HS transport the maximum message size depends on the MTU-size
of the HS-device bound to the AF_IUCV socket. This patch adds a
getsockopt option MSGSIZE returning the maximum message size that
can be handled for this AF_IUCV socket.

Subject: [PATCH 1367/6423] qeth: add wake_up on write channel

To send commands on the write channel 8 buffers exist. If all
8 buffers are used, a wait is triggered on the write channel. When
such buffer are freed, a wake_up is needed. This patch adds the
missing wake_up in qeth_release_buffer().
This fix is especially important when running Communications
Controller for Linux on System z.

It turns out acpi_processor_power_init() get called two time in acpi_processor_add and acpi_processor_start.

Found several lines are duplicated in those two functions even related commit move them.

The related patches are ok.  Not sure how it could happen, looks like git problem.

Subject: [PATCH 1375/6423] staging: android: logger: simplify and optimize
 get_entry_len

Make this code slightly easier to read, and eliminate calls
to sub-routines.  Some of these were previously optimized away
by the compiler, but one memcpy was not.

In my testing, this makes the code about 20% smaller, and
has no sub-routine calls and no branches (on ARM).

v2 of this patch is, IMHO, easier to read than v1. Compared to
that patch it uses __u8 instead of unsigned char, for
consistency with the __u16 val data type, simplifies the
conditional expression, adds a another comment, and
moves a common statement out of the if.

Subject: [PATCH 1379/6423] staging: android/lowmemorykiller: Don't grab
 tasklist_lock

Grabbing tasklist_lock has its disadvantages, i.e. it blocks
process creation and destruction. If there are lots of processes,
blocking doesn't sound as a great idea.

For LMK, it is sufficient to surround tasks list traverse with
rcu_read_{,un}lock().

>From now on using force_sig() is not safe, as it can race with an
already exiting task, so we use send_sig() now. As a downside, it
won't kill PID namespace init processes, but that's not what we
want anyway.

Subject: [PATCH 1380/6423] staging: android/lowmemorykiller: Better mm
 handling

LMK should not directly check for task->mm. The reason is that the
process' threads may exit or detach its mm via use_mm(), but other
threads may still have a valid mm. To catch this we use
find_lock_task_mm(), which walks up all threads and returns an
appropriate task (with lock held).

Subject: [PATCH 1386/6423] staging: ramster: cluster/messaging foundation

Copy cluster subdirectory from ocfs2.  These files implement
the basic cluster discovery, mapping, heartbeat / keepalive, and
messaging ("o2net") that ramster requires for internode communication.
Note: there are NO ramster-specific changes yet; this commit
does NOT pass checkpatch since the copied source files do not.

(Why copy?  This particular part of ocfs2 has never been broken out
for non-ocfs2 use before, some (small) changes are required for ramster
to use that code, and ramster is currently incompatible with real
ocfs2 anyway (requires !CONFIG_OCFS2_FS).  Before ramster can be promoted
out of staging, we will need to work with the ocfs2 maintainers to
see if the code interdependencies can be merged, but for now, for
staging, this seemed to be an expedient way to make use of the ocfs2
core cluster code while still incorporating necessary changes for ramster.)

+ * For now this is a trivial wrapper around printk() that gives the critical
+ * ability to enable sets of debugging output at run-time.  In the future this
+ * will almost certainly be redirected to relayfs so that it can pay a
+ * substantially lower heisenberg tax.
+ *
+ * Callers associate the message with a bitmask and a global bitmask is
+ * maintained with help from /proc.  If any of the bits match the message is
+ * output.
+ *
+ * We must have efficient bit tests on i386 and it seems gcc still emits crazy
+ * code for the 64bit compare.  It emits very good code for the dual unsigned
+ * long tests, though, completely avoiding tests that can never pass if the
+ * caller gives a constant bitmask that fills one of the longs with all 0s.  So
+ * the desire is to have almost all of the calls decided on by comparing just
+ * one of the longs.  This leads to having infrequently given bits that are
+ * frequently matched in the high bits.
+ *
+ * _ERROR and _NOTICE are used for messages that always go to the console and
+ * have appropriate KERN_ prefixes.  We wrap these in our function instead of
+ * just calling printk() so that this can eventually make its way through
+ * relayfs along with the debugging messages.  Everything else gets KERN_DEBUG.
+ * The inline tests and macro dance give GCC the opportunity to quite cleverly
+ * only emit the appropriage printk() when the caller passes in a constant
+ * mask, as is almost always the case.
+ *
+ * All this bitmask nonsense is managed from the files under
+ * /sys/fs/o2cb/logmask/.  Reading the files gives a straightforward
+ * indication of which bits are allowed (allow) or denied (off/deny).
+ * 	ENTRY deny
+ * 	EXIT deny
+ * 	TCP off
+ * 	MSG off
+ * 	SOCKET off
+ * 	ERROR allow
+ * 	NOTICE allow
+ *
+ * Writing changes the state of a given bit and requires a strictly formatted
+ * single write() call:
+ *
+ * 	write(fd, "allow", 5);
+ *
+ * Echoing allow/deny/off string into the logmask files can flip the bits
+ * on or off as expected; here is the bash script for example:
+ *
+ * log_mask="/sys/fs/o2cb/log_mask"
+ * for node in ENTRY EXIT TCP MSG SOCKET ERROR NOTICE; do
+ *	echo allow >"$log_mask"/"$node"
+ * done
+ *
+ * The debugfs.ocfs2 tool can also flip the bits with the -l option:
+ *

+ * There are huge opportunities for races here.  After we give up on a node's
+ * connection we need to wait long enough to give heartbeat an opportunity
+ * to declare the node as truly dead.  We also need to be careful with the
+ * race between when we see a node start heartbeating and when we connect
+ * to it.

+ *
+ * Callers for this were originally written against a very simple synchronus
+ * API.  This implementation reflects those simple callers.  Some day I'm sure
+ * we'll need to move to a more robust posting/callback mechanism.
+ *
+ * Transmit calls pass in kernel virtual addresses and block copying this into
+ * the socket's tx buffers via a usual blocking sendmsg.  They'll block waiting
+ * for a failed socket to timeout.  TX callers can also pass in a poniter to an
+ * 'int' which gets filled with an errno off the wire in response to the
+ * message they send.
+ *
+ * Handlers for unsolicited messages are registered.  Each socket has a page
+ * that incoming data is copied into.  First the header, then the data.
+ * Handlers are called from only one thread with a reference to this per-socket
+ * page.  This page is destroyed after the handler call, so it can't be
+ * referenced beyond the call.  Handlers may block but are discouraged from
+ * doing so.
+ *
+ * Any framing errors (bad magic, large payload lengths) close a connection.
+ *
+ * Our sock_container holds the state we associate with a socket.  It's current
+ * framing state is held there as well as the refcounting we do around when it
+ * is safe to tear down the socket.  The socket is only finally torn down from
+ * the container when the container loses all of its references -- so as long
+ * as you hold a ref on the container you can trust that the socket is valid
+ * for use with kernel socket APIs.
+ *
+ * Connections are initiated between a pair of nodes when the node with the
+ * higher node number gets a heartbeat callback which indicates that the lower
+ * numbered node has started heartbeating.  The lower numbered node is passive
+ * and only accepts the connection if the higher numbered node is heartbeating.

From ba351b02ab11616b08b9220dacd49b20415b1f80 Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Mon, 30 Jan 2012 14:39:18 -0800
Subject: [PATCH 1387/6423] staging: ramster: local compression + tmem

Copy files from drivers/staging/zcache.  Ramster compresses pages
locally before transmitting them to another node, so we can
leverage the zcache and tmem code directly.  Note: there are
no ramster-specific changes yet to these files.

(Why copy?  The ramster tmem.c/tmem.h changes are definitely shareable
between zcache and ramster; the eventual destination for tmem.c
is the linux lib directory.  Ramster changes to zcache are more substantial
and zcache is currently undergoing some significant unrelated changes
(including a new allocator and breaking zcache-main.c into smaller files),
so it seemed best to branch temporarily and merge later.)

+ * In-kernel transcendent memory (generic implementation)
+ *
+ * Copyright (c) 2009-2011, Dan Magenheimer, Oracle Corp.
+ *
+ * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
+ * "handles" (triples containing a pool id, and object id, and an index), to
+ * pages in a page-accessible memory (PAM).  Tmem references the PAM pages via
+ * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
+ * set of functions (pamops).  Each pampd contains some representation of
+ * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
+ * pages and must be able to insert, find, and delete these pages at a
+ * potential frequency of thousands per second concurrently across many CPUs,
+ * (and, if used with KVM, across many vcpus across many guests).
+ * Tmem is tracked with a hierarchy of data structures, organized by
+ * the elements in a handle-tuple: pool_id, object_id, and page index.
+ * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
+ * Each pool, contains a hash table of rb_trees of tmem_objs.  Each
+ * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
+ * nodes called tmem_objnodes.  Each leaf pointer in this tree points to
+ * a pampd, which is accessible only through a small set of callbacks
+ * registered by the PAM implementation (see tmem_register_pamops). Tmem
+ * does all memory allocation via a set of callbacks registered by the tmem
+ * host implementation (e.g. see tmem_register_hostops).

From b083e8619c84503e80e681504cabfb647e715edc Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Mon, 30 Jan 2012 14:39:18 -0800
Subject: [PATCH 1388/6423] staging: ramster: ramster-specific changes to
 cluster code

Ramster-specific changes to ocfs2 cluster foundation, including:
A method for fooling the o2 heartbeat into starting without
an ocfs2 filesystem; a new message mechanism ("data magic") for handling
a reply to a message requesting data; a hack for keeping the cluster
alive even after timeouts so cluster machines can be rebooted separately.

From 0fb3860a8212bfce09e4c53ab342b84adb934159 Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Mon, 30 Jan 2012 14:39:19 -0800
Subject: [PATCH 1389/6423] staging: ramster: ramster-specific changes to
 zcache/tmem

In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle
incoming data resulting from an async get) routines combine with a handful
of changes to existing pamops interfaces allow the generic tmem code
to support asynchronous operations.  Also, a new tmem_xhandle struct
groups together key information that must be passed to remote tmem stores.

Zcache-main.c is augmented with a large amount of ramster-specific code
to handle remote operations and "foreign" pages on both ends of the
"remotify" protocol.  New "foreign" pools are auto-created on demand.
A "selfshrinker" thread periodically repatriates remote persistent pages
when local memory conditions allow.  For certain operations, a queue is
necessary to guarantee strict ordering as out-of-order puts/flushes can
cause strange race conditions.  Pampd pointers now either point to local
memory OR describe a remote page; to allow the same 64-bits to describe
either, the LSB is used to differentiate.  Some acrobatics must be performed
to ensure local memory is available to handle a remote persistent get,
or deal with the data directly anyway if the malloc failed.  Lots
of ramster-specific statistics are available via sysfs.

Note: Some debug ifdefs left in for now.

-	  Zcache doubles RAM efficiency while providing a significant
-	  performance boosts on many workloads.  Zcache uses lzo1x
-	  compression and an in-kernel implementation of transcendent
-	  memory to store clean page cache pages and swap in RAM,
-	  providing a noticeable reduction in disk I/O.
+	  RAMster allows RAM on other machines in a cluster to be utilized
+	  dynamically and symmetrically instead of swapping to a local swap
+	  disk, thus improving performance on memory-constrained workloads
+	  while minimizing total RAM across the cluster.  RAMster, like
+	  zcache, compresses swap pages into local RAM, but then remotifies
+	  the compressed pages to another node in the RAMster cluster.

From 14a3cd58dd4fa10df8d84b37efae1e92962ad372 Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Mon, 30 Jan 2012 14:39:19 -0800
Subject: [PATCH 1390/6423] staging: ramster: ramster-specific new files

New files for ramster support:  The file ramster.h declares externs
and some pampd bitfield manipulation.  The file zcache.h declares
some zcache functions that now must be accessed from the ramster
glue code.  The file ramster_o2net.c is the glue between
zcache and the o2net messaging code, providing routines called
from zcache that initiate messages, and routines that handle
messages by calling zcache. TODO explains future plans for merging.

+For this staging driver, RAMster duplicates code from fs/ocfs2/cluster
+and from drivers/staging/zcache, then incorporates changes to the local
+copy of the code.  Before RAMster can be promoted from staging, this code
+duplication must be resolved.  Specifically, we will first need to work with
+the ocfs2 maintainers to split out the ocfs2 core cluster code so that
+it can be easily included by another subsystem, even if ocfs2 is not
+configured, and also to merge the handful of functional changes required.
+Second, the zcache and RAMster drivers should be either merged or reorganized
+to separate out common code.

Subject: [PATCH 1397/6423] Staging: hv: storvsc: Move and cleanup
 storvsc_remove()

Relocate the storvsc_remove() function to a different location in the file
and invoke scsi_host_put() only after all the cleanup.

Subject: [PATCH 1407/6423] staging: zcache: crypto API support

This patch allow zcache to use the crypto API for page compression.
It replaces the direct LZO compress/decompress calls with calls
into the crypto compression API. The compressor to be used is
specified in the kernel boot line with the zcache parameter like:
zcache=lzo or zcache=deflate.  If the specified compressor can't
be loaded, zcache uses lzo as the default compressor.

Subject: [PATCH 1408/6423] staging: zsmalloc: zsmalloc memory allocation
 library

This patch creates a new memory allocation library named
zsmalloc.

NOTE: zsmalloc currently depends on SPARSEMEM for the MAX_PHYSMEM_BITS
value needed to determine the format of the object handle. There may
be a better way to do this.  Feedback is welcome.

+	tristate "Memory allocator for compressed pages"

+	help
+	  zsmalloc is a slab-based memory allocator designed to store
+	  compressed RAM pages.  zsmalloc uses virtual memory mapping
+	  in order to reduce fragmentation.  However, this results in a
+	  non-standard allocator interface where a handle, not a pointer, is
+	  returned by an alloc().  This handle must be mapped in order to
+	  access the allocated space.

Subject: [PATCH 1426/6423] Staging: bcm: Fix an integer overflow in
 IOCTL_BCM_NVM_READ/WRITE

Variables stNVMReadWrite.uioffset and stNVMReadWrite.uiNumBytes
are chosen from userspace and can be very high. The sum of
these two digits would result in a small number. Therefore,
this patch verifies a negative number was not entered, and
reorganizes the equation to remove the integer overflow.

Subject: [PATCH 1433/6423] Staging: bcm: Use memdup_user rather than
 duplicating its implementation

This is a little bit restricted to reduce false positives

The semantic patch that makes this change is available
in scripts/coccinelle/api/memdup_user.cocci.

Subject: [PATCH 1434/6423] SCSI: fix typo in definition of struct scsi_target

This patch (as1506) corrects a typo in the definition of the
scsi_target structure.  pdt_1f_for_no_lun is supposed to be a
single-bit flag, not a full-sized integer.

Subject: [PATCH 1435/6423] SCSI & usb-storage: add flags for VPD pages and
 REPORT LUNS

This patch (as1507) adds a skip_vpd_pages flag to struct scsi_device
and a no_report_luns flag to struct scsi_target.  The first is used to
control whether sd will look at VPD pages for information on block
provisioning, limits, and characteristics.  The second prevents
scsi_report_lun_scan() from issuing a REPORT LUNS command.

The patch also modifies usb-storage to set the new flag bits for all
USB devices and targets, and to stop adjusting the scsi_level value.

Historically we have seen that USB mass-storage devices often don't
support VPD pages or REPORT LUNS properly.  Until now we have avoided
these things by setting the scsi_level to SCSI_2 for all USB devices.
But this has the side effect of storing the LUN bits into the second
byte of each CDB, and now we have a report of a device which doesn't
like that.  The best solution is to stop abusing scsi_level and
instead have separate flags for VPD pages and REPORT LUNS.

with an error code. The caller assumes the endpoint is not enabled
(which is the case) but it can not enable it again due to this

Subject: [PATCH 1440/6423] usb: gadget: pch_udc: Detecting VBUS through GPIO

Problem:
 In USB Suspend, pch_udc handles 'disconnect'.

Root cause:
 The current pch_udc is not monitoring VBUS.
 When USB cable is disconnected, USB Device Controller generates
 an interrupt of USB Suspend.
 pch_udc cannot distinguish it is USB Suspend or disconnect.
 Therefore, pch_udc handles 'disconnect' after an interrupt of
 USB Suspend happend.

Solution:
 VBUS is detected through GPIO.
 After an interrupt produced USB Suspend, if VBUS is Low,
 pch_udc handles 'disconnect'.
 If VBUS is High, pch_udc handles 'suspend'.

Subject: [PATCH 1441/6423] usb: gadget: pch_udc: Detecting VBUS through GPIO
 with interrupt

Problem:
 pch_udc continues operation even if VBUS becomes Low.
 pch_udc performs D+ pulling up before VBUS becomes High.
 USB device should be controlled according to VBUS state.

Root cause:
 The current pch_udc is not always monitoring VBUS.

Solution:
 The change of VBUS is detected using an interrupt of GPIO.
 If VBUS became Low, pch_udc handles 'disconnect'.
 After VBUS became High, a pull improves D+, and pch_udc
 handles 'connect'.

Subject: [PATCH 1442/6423] usb: gadget: clean the ep in autoconf before
 returning it.

Since commit 72c973dd aka ("usb: gadget: add usb_endpoint_descriptor to
struct usb_ep) the descriptor is part of the ep. Most gadgets like
g_zero or masstorage call config_ep_by_speed() to grab an available
endpoint which may be used for FS/HS/SS bulk/iso/intr and in a second
they assign the proper descriptor by calling config_ep_by_speed(). This
is good so far. A few of them like ncm call config_ep_by_speed() only if
ep->desc not assigned earlier. That means ep->desc is never assigned if
the endpoint was used by another gadget before it was removed.

Some of those gadgets also assign ep->driver_data to NULL on reset or
ep_disable part _but_ keep a reference to this endpoint. At ep_enable
time they assign driver_data to their private data. This probably needs
a clean up of its own.

Subject: [PATCH 1443/6423] usb: gadget: add usb3.0 descriptors to serial
 gadgets

This patch adds SS descriptors to the ACM & generic serial gadget. The
ACM part was tested with minicom + dummy + send / receive files over
ttyACM <=> ttyGS0.
The generic serial part (f_serial) was not tested (haven't found a
driver on the host side).
The nokia & multi gadget use HS at most.

Subject: [PATCH 1444/6423] ALSA: PCM - Add PCM creation API for internal PCMs.

The new ASoC dynamic PCM core needs to create PCMs and substreams that are
for use by internal ASoC drivers only and not visible to userspace for
direct IO. These new PCMs are similar to regular PCMs expect they have no
device nodes or procfs entries. The ASoC component drivers use them in exactly
the same way as regular PCMs for PCM and DAI operations.

The intention is that a dynamic PCM based driver will register both regular
PCMs and internal PCMs. The regular PCMs will be used for all IO with userspace
however the internal PCMs will be used by the driver to route digital audio
through numerous back end DAI links (with potentially a DSP providing different
hw_params, DAI formats based on the regular front end PCM params) to devices
like CODECs, MODEMs, Bluetooth, FM, DMICs, etc

This patch adds a new snd_pcm_new_internal() API call to create the internal PCM
without device nodes or procfs. It also adds adds a new internal flag to snd_pcm.

Subject: [PATCH 1445/6423] Input: Add EVIOC mechanism for MT slots

This patch adds the ability to extract MT slot data via a new ioctl,
EVIOCGMTSLOTS. The function returns an array of slot values for the
specified ABS_MT event type.

Example of user space usage:

struct { unsigned code; int values[64]; } req;
req.code = ABS_MT_POSITION_X;
if (ioctl(fd, EVIOCGMTSLOTS(sizeof(req)), &req) < 0)
	return -1;
for (i = 0; i < 64; i++)
	printf("slot %d: %d\n", i, req.values[i]);

Subject: [PATCH 1446/6423] drm/i915: s/DRM_ERROR/DRM_DEBUG in
 i915_gem_execbuffer.c

These are all user-trigerable, so tune down their loudness a notch.
For some of these we have i-g-t tests (because they prevent
newly-discovered bugs), without this patches running the test suite
leaves behind a dirty dmesg.

Subject: [PATCH 1448/6423] drm: add convenience function to create an range
 property

Creating a range property is a common pattern, so create
a convenience function for this and use it where appropriate.

From fb2a99e15ff0d342de4ba58c84a791224a96a01a Mon Sep 17 00:00:00 2001
From: Sascha Hauer <s.hauer@pengutronix.de>
Date: Mon, 6 Feb 2012 10:58:19 +0100
Subject: [PATCH 1449/6423] drm: do not set fb_info->pixmap fields

The drm drivers set the fb_info->pixmap fields without setting
fb_info->pixmap.addr. If this is not set the fb core will overwrite
these all fb_info->pixmap fields anyway, so there is not much point
in setting them in the first place.

Subject: [PATCH 1450/6423] ASoC: pcm: If pmdown_time is zero then shut down
 DAPM immediately

Since we've already got logic to special case immediate teardown of the
stream we may as well use it if the pmdown_time has been set to zero by
the application layer instead of scheduling a work item with zero delay.

Subject: [PATCH 1454/6423] drm/i915: dump even more into the error_state

Chris Wilson and me have again stared at funny error states and it's
been pretty clear from the start that something was seriously amiss.
The seqnos last seen by the cpu were a few hundred behind those that
the gpu could have possibly emitted last before it died ...

Chris now tracked it down (hopefully, definit verdict's still out),
but in hindsight we'd have found the bug by simply dumping the cpu
side tracking of the ring head and tail registers.

Fix this and prevent an identical time-waster in the future.

Because the hangs always involved semaphores in one way or another,
we've tried to dump the mbox registers, but couldn't find any
inconsistencies. Still, dump them too.

Subject: [PATCH 1455/6423] regulator: Don't add the function name to pr_fmt

Liam pointed out via IM that since we now use the pure function name for
all regulator logging a lot of the messages such as those logging the
constraints are getting a bit noisy due to the implementation detail
that is the function name:

print_constraints: VDDARM: 1000 <--> 1300 mV at 1300 mV at 0 mA

In discussion it seemed like the best thing was to just drop the pr_fmt
and clarify individual log messages where there is an issue otherwise
we get into silly things like renaming the functions to suit the logging.

This is mostly an issue as we have a moderate amount of non-error logging
in the boot sequence to aid debug if something goes wrong since regulator
misconfiguration can kill the system pretty quickly.

this happens, probably the user forgot to specify CHANGE_VOLTAGE.

Subject: [PATCH 1460/6423] drivers: hv: Increase the number of VCPUs supported
 in the guest

The current code arbirarily limited the number of CPUs the guest could have.
Change that so that we can support the maximum number of CPUs the guest can
support. While we use NR_CPUS to size the per-cpu state all we are allocating
based on NR_CPUS are the  pointers to per-cpu state that will be allocatted in
the context of the initializing CPU. This patch triggers a checkpatch warning
for the usage of NR_CPU and since all we are allocating a couple of pointers
per CPU, it should be ok.

Subject: [PATCH 1462/6423] PCI: Add helper macro for pci_register_driver
 boilerplate

This patch introduces the module_pci_driver macro which is a convenience
macro for PCI driver modules similar to module_platform_driver. It is
intended to be used by drivers which init/exit section does nothing but
register/unregister the PCI driver. By using this macro it is possible
to eliminate a few lines of boilerplate code per PCI driver.

Based on work done by Lars-Peter Clausen <lars@metafoo.de> for other
busses (i2c and spi).

Hubs have a flag to indicate whether a given port carries removable devices
or not. This is not strictly accurate in that some built-in devices
will be flagged as removable, but followup patches will make use of platform
data to make this more reliable.

Subject: [PATCH 1466/6423] USB: serial: add macro for console error reporting

Add macro which prints an error message only once if port is used a
console.

Reporting errors in a write path when port is used as a console could
otherwise result in an infinite loop.

There's a real possibility of killing kernel threads that might
have issued use_mm(), so kthread's mm might become non-NULL.

This patch fixes the issue by checking for PF_KTHREAD (just as
get_task_mm()).

Subject: [PATCH 1475/6423] tty: serial: altera_uart: remove
 early_altera_uart_setup

The function has no users inside the tree and the nios2
(out-of-mainline) port doesn't use it either (anymore).

Subject: [PATCH 1478/6423] staging: r8712u: Simplify semaphores

I am preparing to convert this driver from semaphore to mutex locking,
The first step has been to eliminate a number of semaphores that were
initialized but never used, and one whose only use was a single "up"
after initialization. A total of 9 semaphores were removed in this process.

One other change was to remove some inline semaphore routines that were
unused.

In addition, several cases had the following structure:

down()
if () {
   ...
}
up()

The locking overhead was reduced by moving the up/down inside the if
block.

 crystalhd_stop_tx_dma_engine()

The intent here is to see if we have cleared the DMA_START_BIT flag.  We
clear it a couple lines later.  The current code has a precedence bug so
it is equivalent to "if (!dma_cntrl) { ...".

Subject: [PATCH 1483/6423] staging: line6: separate handling of buffer
 allocation and stream startup

There are several features of the Line6 USB driver which require PCM
data to be exchanged with the device:
*) PCM playback and capture via ALSA
*) software monitoring (for devices without hardware monitoring)
*) optional impulse response measurement
However, from the device's point of view, there is just a single
capture and playback stream, which must be shared between these
subsystems. It is therefore necessary to maintain the state of the
subsystems with respect to PCM usage. We define several constants of
the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
following meanings:
*) <subsystem> is one of
-) ALSA: PCM playback and capture via ALSA
-) MONITOR: software monitoring
-) IMPULSE: optional impulse response measurement
*) <direction> is one of
-) PLAYBACK: audio output (from host to device)
-) CAPTURE: audio input (from device to host)
*) <resource> is one of
-) BUFFER: buffer required by PCM data stream
-) STREAM: actual PCM data stream

The subsystems call line6_pcm_acquire() to acquire the (shared)
resources needed for a particular operation (e.g., allocate the buffer
for ALSA playback or start the capture stream for software monitoring).
When a resource is no longer needed, it is released by calling
line6_pcm_release(). Buffer allocation and stream startup are handled
separately to allow the ALSA kernel driver to perform them at
appropriate places (since the callback which starts a PCM stream is not
allowed to sleep).

-	PCM mode bits and masks.

-	"IMPULSE": optional impulse response operation
+	PCM mode bits.
+
+	There are several features of the Line6 USB driver which require PCM
+	data to be exchanged with the device:
+	*) PCM playback and capture via ALSA
+	*) software monitoring (for devices without hardware monitoring)
+	*) optional impulse response measurement
+	However, from the device's point of view, there is just a single
+	capture and playback stream, which must be shared between these
+	subsystems. It is therefore necessary to maintain the state of the
+	subsystems with respect to PCM usage. We define several constants of
+	the form LINE6_BIT_PCM_<subsystem>_<direction>_<resource> with the
+	following meanings:
+	*) <subsystem> is one of
+	-) ALSA: PCM playback and capture via ALSA
+	-) MONITOR: software monitoring
+	-) IMPULSE: optional impulse response measurement
+	*) <direction> is one of
+	-) PLAYBACK: audio output (from host to device)
+	-) CAPTURE: audio input (from device to host)
+	*) <resource> is one of
+	-) BUFFER: buffer required by PCM data stream
+	-) STREAM: actual PCM data stream
+
+	The subsystems call line6_pcm_acquire() to acquire the (shared)
+	resources needed for a particular operation (e.g., allocate the buffer
+	for ALSA playback or start the capture stream for software monitoring).
+	When a resource is no longer needed, it is released by calling
+	line6_pcm_release(). Buffer allocation and stream startup are handled
+	separately to allow the ALSA kernel driver to perform them at
+	appropriate places (since the callback which starts a PCM stream is not
+	allowed to sleep).

Subject: [PATCH 1493/6423] staging, vt6656/wpactl.c: A basic style cleanup

This patch cleans up the coding style in
drivers/staging/vt6656/wpactl.c to closer match the generally accepted
kernel CodingStyle. It is by no means a "make it perfect" patch, but
it does get the file a fair bit closer to matching the accepted style
(whomever was involved in the evolution of this file seriously need to
configure their editors to maintain a consistent style - it was a
mess).

Besides pure style cleanups I also took the liberty of removing some
pointless parens, some unneeded casts and removing some commented out code
(it was obviously not used and git has it if it's ever needed in the
future).

Subject: [PATCH 1494/6423] staging, vt6656/wpactl.c: Fix mem leak in
 wpa_ioctl()

If we hit the default case in the switch statement in wpa_ioctl()
we'll leak the memory allocated to 'param' when the variable goes out
of scope without having been assigned to anything.

This patch fixes the leak by kfree()'ing the memory before we return
from the function.

Subject: [PATCH 1495/6423] staging/xgifb: Remove unsupported mode LCD_320x480

This patch removes the probed mode LCD_320x480 which isn't supported
anyway since this mode falls through to the default (=invalid) mode in
the
XGIfb_validate_mode function (see line 529 ff. for details. the
commented out code for this mode is also removed).

By removing this assignment, we can use the LCD_TYPEs from the sis
driver without modifications.

Subject: [PATCH 1496/6423] staging/xgifb: Include sis headers

This patch includes the headers of the sis driver and reorders some
includes.

Since the xgi driver used to redefine a lot of stuff from the sis
driver, we can simply include the headers of the sis driver itself, so
we can remove duplicated stuff later on.

This patch removes the usage of some xgi structs and defines and
replaces them with the _identical_ structs from the sis headers.
Thus the old structs and defines can be removed.

Subject: [PATCH 1502/6423] staging: xgifb: checkpatch cleanup printk() ->
 pr_lvl()

Rewrote code to use pr_lvl() instead of printk().  There are still a few
instances of printk(), mainly in the debug code which looks like it's going to
be dropped/rewrote (most of it is blocked out).

Uppercase function names are not pretty. Also the code flow readability is
enhanced.

Subject: [PATCH 1504/6423] staging: tidspbridge: remove unused header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

No functional changes.

The header file drv_interface.h was only used locally, hence there's no need
to have it.

Also the only prototyped functions were the file_operations callbacks, then
this commit moves them up to avoid prototyping too.

When compiling this report is raised by the compiler:

  CC [M]  drivers/staging/tidspbridge/rmgr/drv_interface.o
drivers/staging/tidspbridge/rmgr/drv_interface.c: In function 'bridge_mmap':
drivers/staging/tidspbridge/rmgr/drv_interface.c:275:2: warning: format '%lx' expects type 'long unsigned int', but argument 9 has type 'pgprot_t'

This patch fixes that warning message.

The function dsp_deinit() always return true, so assert its output is
pointless. As consequence the variable were the returned value is stored, is
no longer needed.

Subject: [PATCH 1511/6423] staging: tidspbridge: Rename module from
 bridgedriver to tidspbridge

tidspbridge when built as a module is named bridgedriver.

bridgedriver is not a particularly good module name.

tidspbridge is what the source is named.  That seems
a more appropriate module name too as it describes
the hardware function better.

The kernel does not use a "Design by Contract" approach, and it is only
activated in the module if CONFIG_TIDSPBRDIGE_DEBUG is enabled, so they are
executed rarely. It is better to remove them: less code to maintain.

Subject: [PATCH 1513/6423] staging: tidspbridge: remove DBC_ASSERT macro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This macro is only valid when CONFIG_TIDSPBRDIGE_DEBUG is enabled and it only
prints a log message, it is not a real assertion mechanism like BUG_ON() or
WARN_ON().

It is better to remove them: less code to maintain.

Subject: [PATCH 1514/6423] staging: tidspbridge: remove dbc.h
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

All the macros in dbc.h are removed now so this patch removes it completely.

Subject: [PATCH 1515/6423] staging: tidspbridge: remove
 CONFIG_TIDSPBRIDGE_DEBUG
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since all the asserts and DBC macros are gone, the kconfig macro
CONFIG_TIDSPBRIDGE_DEBUG is not almost used, but for printing trace messages.

Since it is almost not used, I don't see any case for keep it churning the
configuration menu.

This patch removes completely the kconfig macro CONFIG_TIDSPBRIDGE_DEBUG,
using only TIDSPBRIDGE_BACKTRACE for enabling the debug trace messages.

Subject: [PATCH 1525/6423] staging/mei: add mei user space example

this example tries to connect to amt host interface client and retrieve
versions of its sub components

When AMT is enabled an output might look like that:
Intel AMT: ENABLED
Flash:	6.1.0
Netstack:	6.1.0
AMTApps:	6.1.0
AMT:	6.1.0
Sku:	258
VendorID:	8086
Build Number:	1042
Recovery Version:	6.1.0
Recovery Build Num:	1042
Legacy Mode:	False

otherwise:
Intel AMT: DISABLED

Subject: [PATCH 1529/6423] staging, media, easycap: Fix mem leak in
 easycap_usb_probe()

If allocating 'pdata_urb' fails, the function will return -ENOMEM
without freeing the memory allocated, just a few lines above, for
'purb' and will leak that memory when 'purb' goes out of scope.

This patch resolves the leak by freeing the allocated storage with
usb_free_urb() before the return.

 PXIe-6251

Paul Fulmek reports that PXIe-6251 works the same as the existing
PCIe-6251 and just needs the new PCI device ID adding to ni_pci_table[]
and a new entry adding to ni_boards[] based on the existing entry for
PCIe-6251.

The new entry has PCI device ID 0x72e8 and board name "pxie-6251".

Thanks Paul!

This patch is ported over by me (Ian Abbott) from the out-of-tree Comedi
git repository at "git://comedi.org/git/comedi/comedi.git".

The original patch is by Nicholas Nell.

-----
Advantech PCI-1739U support

Hello,

I've added a bit of simple configuration to adv_pci_dio.c in order to
make the PCI-1739U work with the adv_pci_dio driver. I have tested
inputs only so far but they seem to work. A git style patch is
attached.

Thanks,

 when setting up DMA.

When setting up the DMA for 'read' streaming acquisition on the DIO
subdevice, mark the whole buffer as writable before starting the DMA.
This prevents a spurious detection of a DMA overwrite of good data
during the first interrupt.

Problem reported by Nicholas Nell.  Fix suggested by Frank Mori Hess.

Subject: [PATCH 1538/6423] staging: comedi: ni_pcidio: Support trailing edge
 external trigger

This patch is ported over by me (Ian Abbott) from the out-of-tree Comedi
git repository at "git://comedi.org/git/comedi/comedi.git".

The original patch is by Nicholas Nell.

The patch adds support for trailing (falling) edge external triggers for
scans in asynchronous command support in the ni_pcidio driver.  This is
supported at least on the PCI-DIO_32HS and PCI-6533 boards; not sure
about the other boards.

Subject: [PATCH 1543/6423] staging:iio: Update iio_event_interface
 documentation

The documentation for the iio_event_interface does not match the actual struct
anymore. This patch removes the documentation for non-existing fields and adds
documentation for missing fields.

Subject: [PATCH 1544/6423] staging:iio: Factor out event handling into its own
 file

The core iio file has gotten quite cluttered over time. This patch moves
the event handling code into its own file. Since the event handling code is
largely independent from the core code the only code changes necessary for
this are to make the moved iio_device_register_eventset,
iio_device_unregister_eventset and iio_event_getfd functions non static.

This has also the advantage that industrialio-core.c is now closer again to
its counterpart in the outofstaging branch.

Subject: [PATCH 1545/6423] staging:iio:events: Use kfifo for event queue

The current IIO event code uses a list to emulate FIFO like behavior.
Just use a kfifo directly instead to implement the event queue. As part of this
patch the maximum of events in the queue is increased from 10 to 16 since kfifo
requires a power of two for the number of FIFO elements.

Subject: [PATCH 1546/6423] staging:iio:events: Use waitqueue lock to protect
 event queue

Use the waitqueue lock to protect the event queue instead of a custom mutex.
This has the advantage that we can call the waitqueue operations with the lock
held, which simplifies the code flow a bit.

Subject: [PATCH 1547/6423] staging:iio:events: Add poll support

Add poll support to the event queue. This will allow us to check for pending
events in a application's event loop using poll() or similar. Since we already
have support for blocking reads adding poll support as well is trivial.

Subject: [PATCH 1548/6423] staging:iio:events: Use non-atmoic bitops

We always hold the waitqueue lock when modifying the flags field. So it is safe
to use the non-atomic bitops here instead of the atomic versions.

The lock has to be held, because we need to clear the busy flag and flush the
event FIFO in one atomic operation when closing the event file descriptor.

This is the most controversial of this set of is_visible removals.
There are two conditions controlling availability of attrs resulting
in 4 different attribute groups.

Still for a few more lines things are clearer to read to my mind.

Subject: [PATCH 1553/6423] staging:iio:adc:adt7310/7410 sticking plaster fix
 for broken event attrs.

Neither of these drivers has ever been anywhere near the iio abi.
Probably as a result of this the fact they had two event groups
each was not picked up when we restricted IIO to having only
1 event line per device (as part of the chrdev merge set).

As such these definitely didn't work before.  This patch squishes
the only element from the 'comparator' event line that isn't in the
'interrupt' one into it and kills off the 'comparator' one.

Ultimately both of these drivers belong in hwmon not IIO and are just
waiting here because I don't want to kill off a driver that may
prove useful to someone.  (Ultimately I will ask Greg to scrap
these two if no one steps up to deal with them.)

Subject: [PATCH 1554/6423] staging: zcache: fix serialization bug in zv stats

In a multithreaded workload, the zv_curr_dist_counts
and zv_cumul_dist_counts statistics are being corrupted
because the increments and decrements in zv_create
and zv_free are not atomic.

This patch converts these statistics and their corresponding
increments/decrements/reads to atomic operations.

Subject: [PATCH 1558/6423] rtlwifi: Modify rtl_pci_init to return 0 on success

Fixes problem where caller would think routine succeeded when it failed
leading to divide by zero panic.

(This also reverts an earlier attempt, commit 42bc0c97 "rtlwifi: Return
correct failure code on error". -- JWL)

To implement a PPGTT for drm/i915 that fully aliases the GTT, we also
need to properly alias the scratch page.

Subject: [PATCH 1561/6423] drm/i915: initialization/teardown for the aliasing
 ppgtt

This just adds the setup and teardown code for the ppgtt PDE and the
last-level pagetables, which are fixed for the entire lifetime, at
least for the moment.

v2: Kill the stray debug printk noted by and improve the pte
definitions as suggested by Chris Wilson.

v3: Clean up the aperture stealing code as noted by Ben Widawsky.

v4: Paint the init code in a more pleasing colour as suggest by Chris
Wilson.

v5: Explain the magic numbers noticed by Ben Widawsky.

From 7bddb01fb9697afd5d39bb69dd9f782a28063101 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1562/6423] drm/i915: ppgtt binding/unbinding support

This adds support to bind/unbind objects and wires it up. Objects are
only put into the ppgtt when necessary, i.e. at execbuf time.

Objects are still unconditionally put into the global gtt.

v2: Kill the quick hack and explicitly pass cache_level to ppgtt_bind
like for the global gtt function. Noticed by Chris Wilson.

Subject: [PATCH 1565/6423] drm/i915: enable ppgtt

We want to unconditionally enable ppgtt for two reasons:
- Windows uses this on snb and later.
- We need the basic hw support to work before we can think about real
  per-process address spaces and other cool features we want.

But Chris Wilson was complaining all over irc and intel-gfx that this
will blow up if we don't have a module option to disable it. Hence add
one, to prevent this.

ppgtt support seems to slightly change the timings and make crashy
things slightly more or less crashy. Now in my testing and the testing
this got on troublesome snb machines, it seems to have improved things
only. But on ivb it makes quite a few crashes happen much more often,
see

https://bugs.freedesktop.org/show_bug.cgi?id=41353

Luckily Eugeni Dodonov seems to have a set of workarounds that fix
this issue.

v2: Don't try to enable ppgtt on pre-snb.

v3: Pimp commit message and make Chris Wilson less grumpy by adding a
module option.

v4: New try at making Chris Wilson happy.

Subject: [PATCH 1576/6423] security: create task_free security callback

The current LSM interface to cred_free is not sufficient for allowing
an LSM to track the life and death of a task. This patch adds the
task_free hook so that an LSM can clean up resources on task death.

Subject: [PATCH 1577/6423] security: Yama LSM

This adds the Yama Linux Security Module to collect DAC security
improvements (specifically just ptrace restrictions for now) that have
existed in various forms over the years and have been carried outside the
mainline kernel by other Linux distributions like Openwall and grsecurity.

+Yama is a Linux Security Module that collects a number of system-wide DAC
+security protections that are not handled by the core kernel itself. To
+select it at boot time, specify "security=yama" (though this will disable
+any other LSM).
+
+Yama is controlled through sysctl in /proc/sys/kernel/yama:
+
+- ptrace_scope
+
+==============================================================
+
+ptrace_scope:
+
+As Linux grows in popularity, it will become a larger target for
+malware. One particularly troubling weakness of the Linux process
+interfaces is that a single user is able to examine the memory and
+running state of any of their processes. For example, if one application
+(e.g. Pidgin) was compromised, it would be possible for an attacker to
+attach to other running processes (e.g. Firefox, SSH sessions, GPG agent,
+etc) to extract additional credentials and continue to expand the scope
+of their attack without resorting to user-assisted phishing.
+
+This is not a theoretical problem. SSH session hijacking
+(http://www.storm.net.nz/projects/7) and arbitrary code injection
+(http://c-skills.blogspot.com/2007/05/injectso.html) attacks already
+exist and remain possible if ptrace is allowed to operate as before.
+Since ptrace is not commonly used by non-developers and non-admins, system
+builders should be allowed the option to disable this debugging system.
+
+For a solution, some applications use prctl(PR_SET_DUMPABLE, ...) to
+specifically disallow such ptrace attachment (e.g. ssh-agent), but many
+do not. A more general solution is to only allow ptrace directly from a
+parent to a child process (i.e. direct "gdb EXE" and "strace EXE" still
+work), or with CAP_SYS_PTRACE (i.e. "gdb --pid=PID", and "strace -p PID"
+still work as root).
+
+For software that has defined application-specific relationships
+between a debugging process and its inferior (crash handlers, etc),
+prctl(PR_SET_PTRACER, pid, ...) can be used. An inferior can declare which
+other process (and its descendents) are allowed to call PTRACE_ATTACH
+against it. Only one such declared debugging process can exists for
+each inferior at a time. For example, this is used by KDE, Chromium, and
+Firefox's crash handlers, and by Wine for allowing only Wine processes
+to ptrace each other.
+
+0 - classic ptrace permissions: a process can PTRACE_ATTACH to any other
+    process running under the same uid, as long as it is dumpable (i.e.
+    did not transition uids, start privileged, or have called
+    prctl(PR_SET_DUMPABLE...) already).
+
+1 - restricted ptrace: a process must have a predefined relationship
+    with the inferior it wants to call PTRACE_ATTACH on. By default,
+    this relationship is that of only its descendants when the above
+    classic criteria is also met. To change the relationship, an
+    inferior can call prctl(PR_SET_PTRACER, debugger, ...) to declare
+    an allowed debugger PID to call PTRACE_ATTACH on the inferior.
+
+The original children-only logic was based on the restrictions in grsecurity.

Subject: [PATCH 1578/6423] PM / Suspend: Avoid code duplication in suspend
 statistics update

The code
       if (error) {
               suspend_stats.fail++;
               dpm_save_failed_errno(error);
       } else
               suspend_stats.success++;

Appears in the kernel/power/main.c and kernel/power/suspend.c.

This patch just creates a new function to avoid duplicated code.

Subject: [PATCH 1579/6423] PM / Freezer / Docs: Document the beauty of
 freeze/thaw semantics

The way the different freeze/thaw functions encapsulate each other are quite
lovely from a design point of view. And as a side-effect, the way in which
they are invoked (cleaning up on failure for example) differs significantly
from how usual functions are dealt with. This is because of the underlying
semantics that govern the freezing and thawing of various tasks.

This subtle aspect that differentiates these functions from the rest, is
worth documenting.

Many thanks to Tejun Heo for providing enlightenment on this topic.

In the hibernation call path, the kernel threads are frozen inside
hibernation_snapshot(). If we happen to encounter an error further down
the road or if we are exiting early due to a successful freezer test,
then thaw kernel threads before returning to the caller.

Subject: [PATCH 1582/6423] PM / Domains: Provide a dummy dev_gpd_data() when
 generic domains are not used

dev_gpd_data() is a generic macro, also useful for drivers. Hence it should
be available also when CONFIG_PM_GENERIC_DOMAINS is not selected. OTOH,
to_gpd_data() is so far unused outside of the generic PM domain code and
does not seem to be very useful without CONFIG_PM_GENERIC_DOMAINS.

From: Bruce Allan <bruce.w.allan@intel.com>

Subject: [PATCH 1588/6423] e1000e: pass pointer to hw struct for
 e1000_init_mac_params_XXX()

The e1000_init_mac_params_XXX() functions (where XXX is one of the three
MAC-family types 80003es2lan, 82571 and ich8lan) was not meant to require a
pointer to the adapter struct but does require a pointer to the hw struct.
Pass that pointer in to the functions instead.

 testmode

When implementing the USB2 testmode support via debugfs,
Felipe has committed a mistake when counting the number
of letters of some of the strings, resulting on an off
by one error which prevented some of the Test modes to
be entered properly.

This patch, fixes that mistake.

time_t was used in the signature and key packet headers,
which is typedef of long and is different on 32 and 64 bit architectures.
Signature and key format should be independent of architecture.
Similar to GPG, I have changed the type to uint32_t.

Subject: [PATCH 1604/6423] usb: dwc3: ep0: fix SetFeature(TEST)

When host requests us to enter a test mode,
we cannot directly enter the test mode before
Status Phase is completed, otherwise the core
will never be able to deliver the Status ZLP
to host, because it has already entered the
requested Test Mode.

In order to fix the error, we move the actual
start of Test Mode right after we receive
Transfer Complete event of the status phase.

Subject: [PATCH 1607/6423] drm/i915: clean up interlaced pipeconf bit
 definitions

- Clarify which bits are for which chips.
- Note that gen2 can't do interlaced directly (only via dvo tv chips).
- Move the mask to the top to make it clearer how wide this field is.
- Add defintions for all possible values.

This patch doesn't change any code.

v2: Paulo Zanoni pointed out that the pixel doubling modes do no
longer exist on ivb.

Subject: [PATCH 1608/6423] drm/i915: fixup interlaced vertical timings
 confusion, part 1

We have a pretty decent confusion about vertical timings of interlaced
modes. Peter Ross has written a patch that makes interlace modes work
on a lot more platforms/output combinations by doubling the vertical
timings.

The issue with that patch is that core drm _does_ support specifying
whether we want these vertical timings in fields or frames, we just
haven't managed to consistently use this facility. The relavant
function is drm_mode_set_crtcinfo, which fills in the crtc timing
information.

The first thing to note is that the drm core keeps interlaced modes in
frames, but displays modelines in fields. So when the crtc modeset
helper copies over the mode into adjusted_mode it will already contain
vertical timings in half-frames. The result is that the fixup code in
intel_crtc_mode_fixup doesn't actually do anything (in most cases at
least).

Now gen3+ natively supports interlaced modes and wants the vertical
timings in frames. Which is what sdvo already fixes up, at least under
some conditions.

There are a few other place that demand vertical timings in fields
but never actually deal with interlaced modes, so use frame timings
for consistency, too. These are:
- lvds panel,
- dvo encoders - dvo is the only way gen2 could support interlaced
  mode, but currently we don't support any encoders that do.
- tv out - despite that the tv dac sends out an interlaced signal it
  expects a progressive mode pipe configuration.
All these encoders enforce progressive modes by resetting
interlace_allowed.

Hence we always want crtc vertical timings in frames. Enforce this in
our crtc mode_fixup function and rip out any redudant timing
computations from the encoders' mode_fixup function.

v2-4: Adjust the vertical timings a bit.

v5: Split out the 'subtract-one for interlaced' fixes.

v6: Clarify issues around tv-out and gen2.

Subject: [PATCH 1609/6423] drm/i915: fixup interlaced vertical timings
 confusion, part 2

According to bspec, we need to subtract an additional line from vtotal
for interlaced modes and vblank_end needs to equal vtotal. All other
timing fields do not need this special treatment, so kill it.

Bspec says that this is irrespective of whether the interlaced mode
has an odd or even vtotal, both modes are supported.

Subject: [PATCH 1611/6423] drm/i915: don't allow interlaced pipeconf on gen2

gen2 doesn't support it, so be a bit more paranoid and add a check to
ensure that we never ever set an unsupported interlaced bit.

Ensure that userspace can't set an interlaced mode by resetting
interlace_allowed for the crt on gen2. dvo and lvds are the only other
encoders that gen2 supports and these already disallow interlaced
modes.

Subject: [PATCH 1612/6423] drm/i915: correctly program the VSYNCSHIFT register

The hw seems to use this to correctly insert the required delay
before/after an even/odd interlaced field. This might also explain
why we need to substract 1 half-line from vtotal - if the hw just
adds the delay programmend in VSYNCSHIFT the total frame time would be
about that too long.

These registers seems to only exist on gen4 and later. For paranoia
also program it to 0 for progressive modes, but according to
documentation the hw should just ignore it in this case.

Subject: [PATCH 1615/6423] drm/i915: fixup overlay checks for interlaced modes

The drm core _really_ likes to frob around with the crtc timings and
put halfed vertical timings (in fields) in there. Which confuses the
overlay code, resulting in it's refusal to display anything at the
lower half of an interlaced pipe.

Subject: [PATCH 1617/6423] staging: ramster: delete the driver

Turns out it's not quite ready to be included, thanks to some other work
done in the zcache and zram code, which breaks this driver.

So, delete it for now, per the recommendation of Dan.

-/*
- * For now this is a trivial wrapper around printk() that gives the critical
- * ability to enable sets of debugging output at run-time.  In the future this
- * will almost certainly be redirected to relayfs so that it can pay a
- * substantially lower heisenberg tax.
- *
- * Callers associate the message with a bitmask and a global bitmask is
- * maintained with help from /proc.  If any of the bits match the message is
- * output.
- *
- * We must have efficient bit tests on i386 and it seems gcc still emits crazy
- * code for the 64bit compare.  It emits very good code for the dual unsigned
- * long tests, though, completely avoiding tests that can never pass if the
- * caller gives a constant bitmask that fills one of the longs with all 0s.  So
- * the desire is to have almost all of the calls decided on by comparing just
- * one of the longs.  This leads to having infrequently given bits that are
- * frequently matched in the high bits.
- *
- * _ERROR and _NOTICE are used for messages that always go to the console and
- * have appropriate KERN_ prefixes.  We wrap these in our function instead of
- * just calling printk() so that this can eventually make its way through
- * relayfs along with the debugging messages.  Everything else gets KERN_DEBUG.
- * The inline tests and macro dance give GCC the opportunity to quite cleverly
- * only emit the appropriage printk() when the caller passes in a constant
- * mask, as is almost always the case.
- *
- * All this bitmask nonsense is managed from the files under
- * /sys/fs/o2cb/logmask/.  Reading the files gives a straightforward
- * indication of which bits are allowed (allow) or denied (off/deny).
- * 	ENTRY deny
- * 	EXIT deny
- * 	TCP off
- * 	MSG off
- * 	SOCKET off
- * 	ERROR allow
- * 	NOTICE allow
- *
- * Writing changes the state of a given bit and requires a strictly formatted
- * single write() call:
- *
- * 	write(fd, "allow", 5);
- *
- * Echoing allow/deny/off string into the logmask files can flip the bits
- * on or off as expected; here is the bash script for example:
- *
- * log_mask="/sys/fs/o2cb/log_mask"
- * for node in ENTRY EXIT TCP MSG SOCKET ERROR NOTICE; do
- *	echo allow >"$log_mask"/"$node"
- * done
- *
- * The debugfs.ocfs2 tool can also flip the bits with the -l option:
- *
- * debugfs.ocfs2 -l TCP allow

- *
- * There are huge opportunities for races here.  After we give up on a node's

- * to declare the node as truly dead.  We also need to be careful with the
- * race between when we see a node start heartbeating and when we connect
- * to it.

- * So nodes that are in this transtion put a hold on the quorum decision

- * ----
- *
- * Callers for this were originally written against a very simple synchronus
- * API.  This implementation reflects those simple callers.  Some day I'm sure
- * we'll need to move to a more robust posting/callback mechanism.
- *
- * Transmit calls pass in kernel virtual addresses and block copying this into
- * the socket's tx buffers via a usual blocking sendmsg.  They'll block waiting
- * for a failed socket to timeout.  TX callers can also pass in a poniter to an
- * 'int' which gets filled with an errno off the wire in response to the
- * message they send.
- *
- * Handlers for unsolicited messages are registered.  Each socket has a page
- * that incoming data is copied into.  First the header, then the data.
- * Handlers are called from only one thread with a reference to this per-socket
- * page.  This page is destroyed after the handler call, so it can't be
- * referenced beyond the call.  Handlers may block but are discouraged from
- * doing so.
- *
- * Any framing errors (bad magic, large payload lengths) close a connection.
- *
- * Our sock_container holds the state we associate with a socket.  It's current
- * framing state is held there as well as the refcounting we do around when it
- * is safe to tear down the socket.  The socket is only finally torn down from
- * the container when the container loses all of its references -- so as long
- * as you hold a ref on the container you can trust that the socket is valid
- * for use with kernel socket APIs.
- *
- * Connections are initiated between a pair of nodes when the node with the
- * higher node number gets a heartbeat callback which indicates that the lower
- * numbered node has started heartbeating.  The lower numbered node is passive
- * and only accepts the connection if the higher numbered node is heartbeating.

- * In-kernel transcendent memory (generic implementation)
- *
- * Copyright (c) 2009-2011, Dan Magenheimer, Oracle Corp.
- *
- * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
- * "handles" (triples containing a pool id, and object id, and an index), to
- * pages in a page-accessible memory (PAM).  Tmem references the PAM pages via
- * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
- * set of functions (pamops).  Each pampd contains some representation of
- * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
- * pages and must be able to insert, find, and delete these pages at a
- * potential frequency of thousands per second concurrently across many CPUs,
- * (and, if used with KVM, across many vcpus across many guests).
- * Tmem is tracked with a hierarchy of data structures, organized by
- * the elements in a handle-tuple: pool_id, object_id, and page index.
- * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
- * Each pool, contains a hash table of rb_trees of tmem_objs.  Each
- * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
- * nodes called tmem_objnodes.  Each leaf pointer in this tree points to
- * a pampd, which is accessible only through a small set of callbacks
- * registered by the PAM implementation (see tmem_register_pamops). Tmem
- * does all memory allocation via a set of callbacks registered by the tmem
- * host implementation (e.g. see tmem_register_hostops).

- * Zcache provides an in-kernel "host implementation" for transcendent memory
- * and, thus indirectly, for cleancache and frontswap.  Zcache includes two
- * page-accessible memory [1] interfaces, both utilizing lzo1x compression:
- * 1) "compression buddies" ("zbud") is used for ephemeral pages
- * 2) xvmalloc is used for persistent pages.
- * Xvmalloc (based on the TLSF allocator) has very low fragmentation
- * so maximizes space efficiency, while zbud allows pairs (and potentially,
- * in the future, more than a pair of) compressed pages to be closely linked
- * so that reclaiming can be done via the kernel's physical-page-oriented
- * "shrinker" interface.
- *
- * [1] For a definition of page-accessible memory (aka PAM), see:

Subject: [PATCH 1618/6423] staging/xgifb: Include sis initdef.h header

This patch includes the initdef.h header from the sis driver.
Since the xgi driver used to redefine a lot of stuff from the sis
driver, we can simply include the headers of the sis driver itself, so
we can remove duplicated stuff later on.

In order to include the initdef.h we have to rename the header guards.

This patch renames the Panel* defines and their usage to the naming
convention of the sis initdef.h and removes the now duplicated defines.

Renames:
Panel320x480 -> Panel_320x480
Panel800x600 -> Panel_800x600
Panel1024x768 -> Panel_1024x768
Panel1024x768x75 -> Panel_1024x768x75
Panel1280x1024 -> Panel_1280x1024
Panel1280x1024x75 -> Panel_1280x1024x75
Panel1280x960 -> Panel_1280x960

From 599801f9266178ebca7f22996b9e6e00f0e69056 Mon Sep 17 00:00:00 2001
From: Peter Huewe <peterhuewe@gmx.de>
Date: Thu, 9 Feb 2012 21:11:45 +0100
Subject: [PATCH 1620/6423] staging/xgifb: Rename Set* defines and remove
 duplicated defines

This patch renames the Set* defines and their usage to the naming
convention of the sis initdef.h and removes the now duplicated defines.

Renames:
SetCRT2ToHiVisionTV -> SetCRT2ToHiVision
SetCRT2ToYPbPr -> SetCRT2ToYPbPr525750

SetNTSCJ -> TVSetNTSCJ
SetPALMTV -> TVSetPALM
SetPALNTV -> TVSetPALN
SetPALTV -> TVSetPAL

SetYPbPrMode1080i -> TVSetHiVision
SetYPbPrMode525i -> TVSetYPbPr525i
SetYPbPrMode525p -> TVSetYPbPr525p
SetYPbPrMode750p -> TVSetYPbPr750p

Subject: [PATCH 1621/6423] staging/xgifb: Rename remaining sis initdef.h
 defines and remove duplicates

This patch renames the remaining duplicate defines and their usage to
the naming convention of the sis initdef.h and removes the now duplicated
defines.

Renames:
CRT2DisplayFlag -> DisableCRT2Display
ModeInfoFlag -> ModeTypeMask

Support16Bpp -> Mode16Bpp
Support32Bpp -> Mode32Bpp

SupportHiVisionTV -> SupportHiVision
SupportYPbPr -> SupportYPbPr750p
SwitchToCRT2 -> SwitchCRT2

VB_XGI301 -> VB_SIS301
VB_XGI301B -> VB_SIS301B
VB_XGI301LV -> VB_SIS301LV
VB_XGI302B -> VB_SIS302B
VB_XGI302LV -> VB_SIS302LV
VB_YPbPr525p -> YPbPr525p
VB_YPbPr750p -> YPbPr750p

VCLK108_2 -> VCLK108_2_315
VCLK65 -> VCLK65_315

XGI_CRT2_PORT_04 -> SIS_CRT2_PORT_04
XGI_CRT2_PORT_10 -> SIS_CRT2_PORT_10
XGI_CRT2_PORT_12 -> SIS_CRT2_PORT_12
XGI_CRT2_PORT_14 -> SIS_CRT2_PORT_14

From a3d675c88fe1ede40386e944e1f3ab5988aeb13c Mon Sep 17 00:00:00 2001

Subject: [PATCH 1622/6423] staging/xgifb: Rename XGI specific initdef.h
 defines

This patch renames some of the defines that exist in the sis initdef.h
but seem to have a different value.
In order to preserve the functionality of the driver, we simply prepend
these defines with XGI_ (for now) to resolve conflicts and review them
later on.

Renames:
SetCRT2ToLCDA -> XGI_SetCRT2ToLCDA
LCDVESATiming -> XGI_LCDVESATiming
EnableLVDSDDA -> XGI_EnableLVDSDDA
LCDDualLink  -> XGI_LCDDualLink
ModeSwitchStatus  -> XGI_ModeSwitchStatus
YPbPr750pVCLK  -> XGI_YPbPr750pVCLK

Subject: [PATCH 1623/6423] staging/xgifb: Use TVCLKBASE_315 as a base address

Since the defines TVVCLKDIV2, TVVCLK, HiTVVCLKDIV2, HiTVVCLK,
HiTVSimuVCLK and HiTVTextVCLK are now defined as relative values, we
have to use TVCLKBASE_315 (0x31) as a base address to get the same values
as before the merge.

The old and now duplicated defines were removed

Subject: [PATCH 1625/6423] staging: r8712u: Add missing initialization and
 remove configuration parameter CONFIG_R8712_AP

When this driver was upgraded to the vendor 20100831 version in
commit 93c55dda092c7 et al,, one listhead initialization was missed.
This broke complete operation of the driver whenever AP mode was
enabled. This fixes https://bugs.archlinux.org/task/27996.

The configuration parameter R8712_AP is misleading as the driver cannot
function as an AP without a heavily hacked version of hostapd. Thus, it
makes sense to remove the parameter; however the code and data configured
for the option is left in.

Subject: [PATCH 1626/6423] Staging: bcm: fix CodingStyle warnings/errors
 reported by checkpatch.pl in led_control.h

This is a patch to the led_control.h file that fixes numerous warnings
and errors reported by the checkpatch.pl tool. There still remain a few
more, but as this is my first attempt at a commit, I'm not going to be
too adventurous!

 preprocessor aliasing
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Older out of tree drivers that were desgined to the Android Alarm
in-kernel API may not build due to the namespace collision fixed in
an earlier patch. Per Arve's suggestion, this patch provides
preprocessor macros that allow older drivers to build.

It's a fairly big set of changes because it has to rework the whole context
handling system.

Subject: [PATCH 1646/6423] USB: serial: fix console error reporting

Do not report errors in write path if port is used as a console as this
may trigger the same error (and error report) resulting in a loop.

Use dev_err_console in write paths for devices which can be used as a
console but do not use the generic write implementation.

Compile-only tested.

From 92b2e5b31dd2ad2c9273578c2289d17f417fe32d Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@infradead.org>
Date: Wed, 1 Feb 2012 13:57:20 +0000
Subject: [PATCH 1649/6423] xfs: use a normal shrinker for the dquot freelist

Stop reusing dquots from the freelist when allocating new ones directly, and
implement a shrinker that actually follows the specifications for the
interface.  The shrinker implementation is still highly suboptimal at this
point, but we can gradually work on it.

This also fixes an bug in the previous lock ordering, where we would take
the hash and dqlist locks inside of the freelist lock against the normal
lock ordering.  This is only solvable by introducing the dispose list,
and thus not when using direct reclaim of unused dquots for new allocations.

As a side-effect the quota upper bound and used to free ratio values in
/proc/fs/xfs/xqm are set to 0 as these values don't make any sense in the
new world order.

Subject: [PATCH 1650/6423] tty: sparc: rename drivers/tty/serial/suncore.h ->
 include/linux/sunserialcore.h

There are multiple users of this file from different source
paths now, and rather than have ../ paths in include statements,
just move the file to the linux header dir.

Subject: [PATCH 1651/6423] viafb: add auxiliary device management
 infrastructure

This patch adds the basic infrastructure and a few stub drivers for
devices that are connected via I2C busses. The infrastructure will
be used to replace and extend the support that is scattered
throughout viafb. The stub drivers are not very useful yet but they
show how the infrastructure works, provide information about the
chips integrated into a system and maybe gather some testers as it
would be very difficult for a single person to get a sane test
environment.
The only thing this actually does is probing the I2C busses which
will hopefully not cause any regressions.

Subject: [PATCH 1652/6423] usb: cdc-wdm: make reset work with blocking IO
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a flag to tell wdm_read/wdm_write that a reset is in progress,
and wake any blocking read/write before taking the mutexes.  This
allows the device to reset without waiting for blocking IO to
finish.

Subject: [PATCH 1653/6423] viafb: set correct polarity for second adapter

This patch sets the correct polarity for the second adapter when
viafb_SAMM_ON is set and viafb_dual_fb is not set. Just one step to
make this mode useful.

Subject: [PATCH 1654/6423] viafb: fill xres and yres

This patch fills xres and yres in var which is required when a
temporary var is genereated when viafb_SAMM_ON is set and
viafb_dual_fb is not set. It also removes an obsolete comment.

Subject: [PATCH 1655/6423] viafb: make single framebuffer multiple adapter
 mode work

This patch implementes this mode (viafb_SAMM_ON set and
viafb_dual_fb not set) in a useful way for CRT and DVI devices.
The same content is shown on both devices in different video modes.
The first (primary) resolution must not be bigger than the secondary
one and determines the visible region. The same content is shown
centered on the secondary output.

Subject: [PATCH 1656/6423] drivers/base: add bus for System-on-Chip devices

Traditionally, any System-on-Chip based platform creates a flat list
of platform_devices directly under /sys/devices/platform.

In order to give these some better structure, this introduces a new
bus type for soc_devices that are registered with the new
soc_device_register() function.  All devices that are on the same
chip should then be registered as child devices of the soc device.

The soc bus also exports a few standardised device attributes which
allow user space to query the specific type of soc.

+What:		/sys/devices/socX
+Date:		January 2012
+contact:	Lee Jones <lee.jones@linaro.org>
+Description:
+		The /sys/devices/ directory contains a sub-directory for each
+		System-on-Chip (SoC) device on a running platform. Information
+		regarding each SoC can be obtained by reading sysfs files. This
+		functionality is only available if implemented by the platform.
+

Subject: [PATCH 1658/6423] ASoC: mxs-saif: use devm_ functions

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

Subject: [PATCH 1659/6423] pinctrl: break out a pinctrl consumer header

This breaks out a <linux/pinctrl/consumer.h> header to be used by
all pinmux and pinconfig alike, so drivers needing services from
pinctrl does not need to include different headers. This is similar
to the approach taken by the regulator API.

Subject: [PATCH 1660/6423] pinctrl: move generic functions to the pinctrl_
 namespace

Since we want to use the former pinmux handles and mapping tables for
generic control involving both muxing and configuration we begin
refactoring by renaming them from pinmux_* to pinctrl_*.

ChangeLog v1->v2:
- Also rename the PINMUX_* macros in machine.h to PIN_ as indicated
  in the documentation so as to reflect the generic nature of these
  mapping entries from now on.

From befe5bdfbb698b3bc57c58d0bd7ca3391c9275ed Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Thu, 9 Feb 2012 19:47:48 +0100
Subject: [PATCH 1661/6423] pinctrl: factor pin control handles over to the
 core

This moves the per-devices struct pinctrl handles and device map
over from the pinmux part of the subsystem to the core pinctrl part.
This makes the device handles core infrastructure with the goal of
using these handles also for pin configuration, so that device
drivers (or boards etc) will need one and only one handle to the
pin control core.

Subject: [PATCH 1662/6423] pinctrl: changes hog mechanism to be
 self-referential

Instead of a specific boolean field to indicate if a map entry shall
be hogged, treat self-reference as an indication of desired hogging.
This drops one field off the map struct and has a nice Douglas R.
Hofstadter-feel to it.

Subject: [PATCH 1664/6423] ixgbe: Minor refactor of RSC

This change addresses several issue.

First I had left the use of the next and prev skb pointers floating around
in the code and they were overdue to be pulled since I had rewritten the
RSC code in the out-of-tree driver some time ago to address issues brought
up by David Miller in regards to this.

I am also now defaulting to always leaving the first buffer unmapped on any
packet and then unmapping it after we read the EOP descriptor.  This allows
a simplification of the path with less branching.

Instead of counting packets received the code was changed some time ago to
track the number of buffers received.  This leads to inaccurate counting
when you compare numbers of packets received by the hardware versus what is
tracked by the software.  To correct this I am revising things so that the
append_cnt value for RSC accurately tracks the number of frames received.

Subject: [PATCH 1665/6423] ixgbe: Address fact that RSC was not setting GSO
 size for incoming frames

This patch is meant to address the fact that RSC has not been setting the
gso_size value on the skb.  As a result performance on lossy TCP
connections was negatively impacted.  This change resolves the issue by
setting gso_size to the average size for incoming packets.

Subject: [PATCH 1666/6423] ixgbe: Let the Rx buffer allocation clear status
 bits instead of cleanup

This change makes it so that we always clear the status/error bits in the
Rx descriptor in the allocation path instead of the cleanup path.  The
advantage to this is that we spend less time modifying data.  As such we
can modify the data once and then let it go cold in the cache instead of
writing it, reading it, and then writing it again.

Subject: [PATCH 1667/6423] ixgbe: Add function for testing status bits in Rx
 descriptor

This change adds a small function for testing Rx status bits in the
descriptor.  The advantage to this is that we can avoid unnecessary
byte swaps on big endian systems.

Subject: [PATCH 1668/6423] ixgbe: Drop the _ADV of descriptor macros since all
 ixgbe descriptors are ADV

It doesn't make much sense to differentiate between advanced and legacy
descriptors when the only descriptors that ixgbe uses are advanced
descriptors.  As such we can drop the _ADV suffix since all ixgbe
descriptors are automatically advanced.

Subject: [PATCH 1669/6423] ixgbe: Combine post-DMA processing of sk_buff
 fields into single function

This change combines a number of post-DMA Rx packet processing functions
into a single function.  The advantage of this is that it combines most of
the Rx descriptor processing into one spot so it should all be warm in the
cache.

Subject: [PATCH 1670/6423] skbuff: Move rxhash and vlan_tci to consolidate
 holes in sk_buff

This change helps to reduce the overall size of the sk_buff by moving
rxhash and vlan_tci so that the u16 values and u8 bitfields can be better
combined to create only one hole instead of multiple.

Subject: [PATCH 1684/6423] ASoC: wm_hubs: Improve single ended line output
 enable performance

The enable of the single ended line outputs on wm_hubs devices performs
better if the output is enabled prior to starting VMID. Since inactive
outputs are held at VMID anyway there is little cost to doing this for
unused outputs. Add callbacks into wm_hubs and keep track of which outputs
are really active so we can disable them once we're active.

Subject: [PATCH 1686/6423] ASoC: wm8994: VMID management improvements

Raise the ramp time to 50ms to cover corner cases, use the startup bias
generator, explicitly reset the ramp circuit when complete and reorder
things all of which should improve performance somewhat for systems that
are sensitive to noise from VMID.

Subject: [PATCH 1688/6423] drm/i915: use gtfifodbg

Add register definitions for GTFIFODBG, and clear it during init time to
make sure state is correct.

This register tells us if either a read, or a write occurred while the
fifo was full. It seems like bit 2 is an OR of bit 0 and bit 1, so we
check that as well, but the documents are not quite clear.

Subject: [PATCH 1689/6423] drm/i915: catch gtfifo errors on forcewake_put

This is similar to a patch I wrote several months ago. It's been updated
for the new FORCEWAKE_MT. As recommended by Chris Wilson, use WARN()
instead of DRM_ERROR, so we can get a backtrace.

This shouldn't impact performance too much as the extra register read
can replace the POSTING_READ we had previously.

Subject: [PATCH 1690/6423] drm/i915: check gtfifodbg after possibly failed
 writes

If we don't have a sufficient number of free entries in the FIFO, we
proceed to do a write anyway. With this check we should have a clue if
that write actually failed or not.

After some discussion with Daniel Vetter regarding his original
complaint, we agreed upon this.

From 21c3fcf3e39353d4f21d50e257cc74f3204b1988 Mon Sep 17 00:00:00 2001
From: Yinghai Lu <yinghai@kernel.org>
Date: Sun, 12 Feb 2012 09:53:57 -0800
Subject: [PATCH 1691/6423] x86/debug: Fix/improve the show_msr=<cpus> debug
 print out

Found out that show_msr=<cpus> is broken, when I asked a
user to use it to capture debug info about broken MTRR's
whose MTRR settings are probably different between CPUs.

Only the first CPUs MSRs are printed, but that is not
enough to track down the suspected bug.

For years we called print_cpu_msr from print_cpu_info(),
but this commit:

| commit 2eaad1fddd7450a48ad464229775f97fbfe8af36
| Author: Mike Travis <travis@sgi.com>
| Date:   Thu Dec 10 17:19:36 2009 -0800
|
|    x86: Limit the number of processor bootup messages

removed the print_cpu_info() call from all APs.

Put it back - it will only print MSRs when the user
specifically requests them via show_msr=<cpus>.

Subject: [PATCH 1697/6423] video: support MIPI-DSI controller driver

Samsung S5PC210 and EXYNOS SoC platform has MIPI-DSI controller and
MIPI-DSI based LCD Panel could be used with it.  This patch supports
MIPI-DSI driver based Samsung SoC chip.

LCD panel driver based MIPI-DSI should be registered to MIPI-DSI driver at
machine code and LCD panel driver specific function registered to
mipi_dsim_ddi structure at lcd panel init function called system init.  In
the MIPI-DSI driver, find lcd panel driver by using registered lcd panel
name, and then initialize lcd panel driver.

Subject: [PATCH 1698/6423] video: backlight: support s6e8ax0 panel driver
 based on MIPI DSI

An moled panel driver based MIPI DSI interface.  S6E8AX0 means it may
includes many other ldi controllers, for example, S6E8AA0, S6E8AB0, and so
on.

This patch can be modified depending on each panel properites.  For
example, second parameter of panel condition register can be changed
depending on ldi controller or amoled type.

Date: Thu, 9 Feb 2012 09:35:49 +0000
Subject: [PATCH 1702/6423] net: implement IP_RECVTOS for IP_PKTOPTIONS

Currently, it is not easily possible to get TOS/DSCP value of packets from
an incoming TCP stream. The mechanism is there, IP_PKTOPTIONS getsockopt
with IP_RECVTOS set, the same way as incoming TTL can be queried. This is
not actually implemented for TOS, though.

This patch adds this functionality, both for IPv4 (IP_PKTOPTIONS) and IPv6
(IPV6_2292PKTOPTIONS). For IPv4, like in the IP_RECVTTL case, the value of
the TOS field is stored from the other party's ACK.

This is needed for proxies which require DSCP transparency. One such example
is at http://zph.bratcheda.org/.

addr_assign_type to NET_ADDR_PERM if the state was
NET_ADDR_RANDOM before. Reset the state since the MAC is
no longer random at least not from the kernel side.

v2: changed to bitops, removed if()

Subject: [PATCH 1704/6423] rename dev_hw_addr_random and remove redundant
 second

Renamed dev_hw_addr_random to eth_hw_addr_random() to reflect that
this function only assign a random ethernet address (MAC). Removed
the second parameter (u8 *hwaddr), it's redundant since the also
given net_device already contains net_device->dev_addr.
Set it directly.

Adapt igbvf and ixgbevf to the changed function.

Small fix for ixgbevf_probe(): if ixgbevf_sw_init() fails
(which means the device got no dev_addr) handle the error and
jump to err_sw_init as already done by igbvf in similar case.

From 10ef9ab4329edd08bccc7a8d34b96b85714195ce Mon Sep 17 00:00:00 2001
From: Sathya Perla <sathya.perla@emulex.com>
Date: Thu, 9 Feb 2012 18:05:27 +0000
Subject: [PATCH 1706/6423] be2net: event queue re-design

v2: Fixed up the bad typecasting pointed out by David...

In the current design 8 TXQs are serviced by 1 EQ, while each RSS queue
is serviced by a separate EQ. This is being changed as follows:

- Upto 8 EQs will be used (based on the availabilty of msix vectors).
Each EQ will handle 1 RSS and 1 TX ring. The default non-RSS RX queue and
MCC queue are handled by the last EQ.

- On cards which provide support, upto 8 RSS rings will be used, instead
of the current limit of 4.

The new design allows spreading the TX multi-queue completion processing
across multiple CPUs unlike the previous design.

Subject: [PATCH 1711/6423] enic: remove assignment of random mac on enic vf

This patch removes random mac assignment on vf's. The vf's will start with
a zero mac and with upcoming support in fw/driver, a vf mac can be set
via the pf. vf's also support ndo_set_mac_address. This decision was made
based on the fact that a random mac on a vf is not really needed. And this
will reduce some of the problems with the vf's getting a new mac on
every driver load/unload (one of them being udev renaming the device on ever
load/unload and reboot).

Subject: [PATCH 1717/6423] drm/i915: fixup seqno allocation logic for
 lazy_request

Currently we reserve seqnos only when we emit the request to the ring
(by bumping dev_priv->next_seqno), but start using it much earlier for
ring->oustanding_lazy_request. When 2 threads compete for the gpu and
run on two different rings (e.g. ddx on blitter vs. compositor)
hilarity ensued, especially when we get constantly interrupted while
reserving buffers.

Breakage seems to have been introduced in

    drm/i915: Use a common seqno for all rings.

This patch fixes up the seqno reservation logic by moving it into
i915_gem_next_request_seqno. The ring->add_request functions now
superflously still return the new seqno through a pointer, that will
be refactored in the next patch.

Note that with this change we now unconditionally allocate a seqno,
even when ->add_request might fail because the rings are full and the
gpu died. But this does not open up a new can of worms because we can
already leave behind an outstanding_request_seqno if e.g. the caller
gets interrupted with a signal while stalling for the gpu in the
eviciton paths. And with the bugfix we only ever have one seqno
allocated per ring (and only that ring), so there are no ordering
issues with multiple outstanding seqnos on the same ring.

v2: Keep i915_gem_get_seqno (but move it to i915_gem.c) to make it
clear that we only have one seqno counter for all rings. Suggested by
Chris Wilson.

v3: As suggested by Chris Wilson use i915_gem_next_request_seqno
instead of ring->oustanding_lazy_request to make the follow-up
refactoring more clearly correct. Also improve the commit message
with issues discussed on irc.

Subject: [PATCH 1718/6423] drm/i915: enable forcewake voodoo also for gen6

We still have reports of missed irqs even on Sandybridge with the
HWSTAM workaround in place. Testing by the bug reporter gets rid of
them with the forcewake voodoo and no HWSTAM writes.

Because I've slightly botched the rebasing I've left out the ACTHD
readback which is also required to get IVB working. Seems to still
work on the tester's machine, so I think we should go with the more
minmal approach on SNB. Especially since I've only found weak evidence
for holding forcewake while waiting for an interrupt to arrive, but
none for the ACTHD readback.

Subject: [PATCH 1719/6423] drm/i915: fix up locking inconsistency around
 gem_do_init

The locking in our setup and teardown paths is rather arbitrary, but
generally we try to protect gem stuff with dev->struct_mutex. Further,
the ums/gem ioctl to setup gem _does_ take the look. So fix up this
benign inconsistency.

Notice while reading through code.

v2: Rebased on top of the ppgtt code.

the auto-mute feature in software.  The auto-mute feature is implemented

Also, rename the fixup index as ALC861_FIXUP_* to follow the standard.

Subject: [PATCH 1726/6423] usb: otg: Separate otg members from usb_phy

Introducing struct otg and collecting otg specific members
to it from struct usb_phy. There are no changes to
struct usb_phy at this stage. This also renames
transceiver specific functions, and offers aliases for the
old otg ones.

Subject: [PATCH 1739/6423] drm/modes: do not enforce an odd vtotal for
 interlaced modes

CEA actually specifies an interlaced mode with even vtotal and
supplies a diagram showing how this is supposed to work.

Note that interlaced modes with an even vtotal seem to be a fairly
recent invention. All modelines lore I could dig up with googling says
that vtotal for interlaced modes _needs_ to be odd. But the even
modelines in CEA are not a spec-bug, there's a figure in CEA-861-E
called "Figure 5 Special Interlaced Video Format Timing (Even Vtotal)"
that explains how it's supposed to work. Furthermore intel Bspec
explicitly mentions that both odd and even interlaced vtotal are
supported (VTOTAL register in the south display engine of PCH split
chips).

Subject: [PATCH 1741/6423] vmwgfx: Clean up pending event references to struct
 drm_file objects on close

Pending events may have stale pointer references to struct drm_file objects
after a file has been closed, but before the event is supposed to be
attached to the drm file. Remove such events on file close.

Tested with "modetest".

Subject: [PATCH 1750/6423] drm/radeon/kms: add support for streamout v7
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

v2: agd5f: add strmout CS checking, copy_dw register checking

v3: agd5f: don't use cs_check_reg() for copy_dw checking as it
will incorrectly patch the command stream for certain regs.

v4: agd5f: add warning if safe reg check fails for copy_dw

v5: agd5f: add stricter checking for 6xx/7xx

v6: agd5f: add range checking for copy_dw on eg+,
add sx_surface_sync to safe reg list for 7xx.

v7: agd5f: add stricter checking for eg+

From 285484e2d55e76031b45926720c10b1aec8b782a Mon Sep 17 00:00:00 2001
From: Jerome Glisse <jglisse@redhat.com>
Date: Fri, 16 Dec 2011 17:03:42 -0500
Subject: [PATCH 1751/6423] drm/radeon: add support for evergreen/ni tiling
 informations v11

evergreen and northern island gpu needs more informations for 2D tiling
than previous r6xx/r7xx. Add field to tiling ioctl to allow userspace
to provide those.

The v8 cs checking change to track color view on r6xx/r7xx doesn't
affect old userspace as old userspace always emited 0 for this register.

v2 fix r6xx/r7xx 2D tiling computation
v3 fix r6xx/r7xx height align for untiled surface & add support for
   tile split on evergreen and newer
v4 improve tiling debugging output
v5 fix tile split code for evergreen and newer
v6 set proper tile split for crtc register
v7 fix tile split limit value
v8 add COLOR_VIEW checking to r6xx/r7xx checker, add evergreen cs
   checking, update safe reg for r600, evergreen and cayman.
   Evergreen checking need some work around for stencil alignment
   issues
v9 fix tile split value range, fix compressed texture handling and
   mipmap calculation, allow evergreen check to be silencious in
   front of current broken userspace (depth/stencil alignment issue)
v10 fix eg 3d texture and compressed texture, fix r600 depth array,
    fix r600 color view computation, add support for evergreen stencil
    split
v11 more verbose debugging in some case

From f6bafc6a1c9d58f0c234ac5052b9c09b0747348c Mon Sep 17 00:00:00 2001
From: Felipe Balbi <balbi@ti.com>
Date: Mon, 6 Feb 2012 11:04:53 +0200
Subject: [PATCH 1752/6423] usb: dwc3: convert TRBs into bitshifts

this will get rid of a useless memcpy on
IRQ handling, thus improving driver performance.

Tested with OMAP5430 running g_mass_storage on
SuperSpeed and HighSpeed.

Note that we are removing the little endian access
of the TRB and all accesses will be in System endianness,
if there happens to be a system in BE, bit 12 of GSBUSCFG0
should be set so that HW does byte invariant BE accesses
when fetching TRBs.

Signed-off-by: Felipe Balbi <balbi@ti.com>

Subject: [PATCH 1753/6423] staging: fix powerpc linux-next break on zsmalloc

linux/vmalloc.h added to zsmalloc-main.c to resolve implicit
declaration errors.

X86 dependency added to zsmalloc and dependent drivers zcache and zram.

This X86 only requirement is not ideal.  Working to find portable
functions for __flush_tlb_one and set_pte.

Subject: [PATCH 1754/6423] Bluetooth: Convert inquiry cache to use standard

This makes it possible to use the convenience functions provided for
standard kernel list types and it also makes it easier to extend the use
of the cache for the management interface where e.g. name resolving
control will be needed.

Subject: [PATCH 1755/6423] Bluetooth: Move Extended Inquiry Response defines
 to hci.h

The EIR defines are needed also outside of mgmt.c (e.g. in hci_event.c
to check if EIR data has the complete name) so it's better to have them
in a single public place, i.e. hci.h.

This patch adds initial support for mgmt_confirm_name. It adds the
necessary tracking of the name state by extending the inquiry cache. The
actual name resolving operation (to be done once inquiry is finished) is
not yet part of this patch.

Subject: [PATCH 1757/6423] Bluetooth: Return updated name state with
 hci_inquiry_cache_update

If user-space has already confirmed the name for a remote device we
shouldn't request confirmation again. The simplest way to do this is to
return the name state from hci_inquiry_cache_update (if it is anything
else than unknown then we do not need confirmation from user-space).

Subject: [PATCH 1758/6423] Bluetooth: Flush inquiry cache when starting mgmt
 triggered inquiry

For the remote name state tracking for the management interface to work
the cache needs to be flushed whenever inquiry is started. The
hci_do_inquiry function is only used by the management interface so by
having the flushing done from it ensures that old ioctl based
functionality isn't affected.

Subject: [PATCH 1760/6423] Bluetooth: Add discovery state tracking

This patch adds proper state tracking to the device discovery process.
This makes it possible to return appropriate errors when trying to stop
a non-active discovery or start discovery when it is already ongoing.
Once name resolving is implemented this also makes it possible to know
what the right action to do is when a remote name lookup is cancelled.

Subject: [PATCH 1761/6423] Bluetooth: Add name resolving support for mgmt
 based discovery

This patch adds the necessary logic to perform name lookups after
inquiry completes. This is done by checking for entries in the resolve
list after each inquiry complete and remote name complete HCI event.

According the documentation in usb_submit_urb() URB_ISO_ASAP
flag is only allowed for endpoints of type USB_ENDPOINT_XFER_ISOC.

This reverts commit b8aabfc92249b239c425da7e4ca85b7e4855e984.

Subject: [PATCH 1764/6423] Bluetooth: Fix sk_sndtimeo initialization for L2CAP
 socket

sk_sndtime value should be specified in jiffies thus initial value
needs to be converted from miliseconds. Otherwise this timeout is
unreliable when CONFIG_HZ is not set to 1000.

Subject: [PATCH 1765/6423] Bluetooth: l2cap_set_timer needs jiffies as timeout
 value

After moving L2CAP timers to workqueues l2cap_set_timer expects timeout
value to be specified in jiffies but constants defined in miliseconds
are used. This makes timeouts unreliable when CONFIG_HZ is not set to
1000.

__set_chan_timer macro still uses jiffies as input to avoid multiple
conversions from/to jiffies for sk_sndtimeo value which is already
specified in jiffies.

Subject: [PATCH 1772/6423] Bluetooth: dtl1: Fix memleak in probe()

We currently leak the driver info structure if dtl1_config fails. If we add a
kfree() to dtl1_release to fix this, then dtl1_release and dtl1_detach are
identical so this merges both functions.

Subject: [PATCH 1773/6423] Bluetooth: Make hci-destruct callback optional

Several drivers already provide an empty callback so we can actually
make this optional and then remove all those empty callbacks in the
drivers.

This callback isn't needed at all by most drivers as they can remove
their allocated structures on device disconnect and not on hci
destruction.

Subject: [PATCH 1780/6423] Bluetooth: vhci: Free driver_data on file release

This removes the hci-destruct callback and instead frees the private
driver data in the vhci_release file release function. There is no
reason to keep private driver data available if the driver has already
shut down.

After vhci_release is called our module can be unloaded. The only reason
it is kept alive is the hci-core having a module-ref on us because of
our destruct callback. However, this callback only frees
hdev->driver_data. That is, we wait for the hdev-device to get destroyed
to free our internal driver-data. In fact, the hci-core does never touch
hdev->driver_data so it doesn't care if it is NULL. Therefore, we simply
free it when unloading the driver.

Another important fact is that the hdev core does not call any callbacks
other than the destruct-cb after hci_unregister_dev() has been called.
So there is no function of our module that will be called nor does the
hci-core touch hdev->driver_data. Hence, no other code can touch
hdev->driver_data after our cleanup so the destruct callback is
definitely unnecessary here.

Subject: [PATCH 1781/6423] Bluetooth: bfusb: Free driver_data on USB shutdown

This frees the private driver data on USB shutdown instead of using the
hci-destruct callback. We already call usb_set_intfdata(intf, NULL) but
we do not do the same with the hci object. This would be totally safe,
though.

After calling hci_unregister_dev()/hci_free_dev() the hdev object will
never call any callback of us again except the destruct callback.
Therefore, we can safely set the destruct callback to NULL and free the
driver data right away.  This allows to unload the module without
waiting for the hdev device to be released.

Instead of using the hci-destruct callback we free our private driver
data on USB shutdown. We already called hci_unregister_dev() here so the
hci core will never ever call our callbacks again except the destruct
callback.

However, there is no reason to keep our *private* driver data alive if
we get never called again and the hci-core does never touch it the data.
So we simply free it right away and set the destruct callback to NULL.

Instead of waiting for the hci-device to be destroyed we now free the
private driver data on driver shutdown right away. We call
hci_unregister_dev() on driver shutdown, that means, the hci-core will
never ever call our callbacks again except the destruct callback. It
also does not access hdev->driver_data so there is no reason to keep
that alive. We simply set the destruct cb to NULL to avoid getting
called again.

Subject: [PATCH 1784/6423] Bluetooth: btsdio: Free driver data on SDIO
 shutdown

Instead of waiting for the hdev object to get freed we now free the
private driver-internal data on SDIO shutdown. This allows us to remove
the obsolete hci-destruct callback and free our data object right away
after calling hci_unregister_dev(). The HCI-core does not call any
callbacks after this so we are never called again and can safely exit
the module.

Subject: [PATCH 1785/6423] Bluetooth: uart-ldisc: Fix memory leak and remove
 destruct cb

We currently leak the hci_uart object if HCI_UART_PROTO_SET is never set
because the hci-destruct callback will then never be called.  This fix
removes the hci-destruct callback and frees the driver internal private
hci_uart object directly on tty-close. We call hci_unregister_dev() here
so the hci-core will never call our callbacks again (except destruct).
Therefore, we can safely free the driver internal data right away and
set the destruct callback to NULL.

Subject: [PATCH 1786/6423] Bluetooth: Remove unused hci-destruct cb

The hci-destruct callback is not used by any driver so we can remove it.
There is no reason to keep it alive, anymore. Drivers can free their
internal data on driver-release and we do not need to provide a public
destruct callback.

Internally, we still use a destruct callback inside of hci_sysfs.c. This
one is used to correctly free our hci_dev data structure if no more
users have a reference to it.

After unregistering an hci_dev object a bluetooth driver does not have
any callbacks in the hci_dev structure left over. Therefore, there is no
need to keep a reference to the module.

Previously, we needed this to protect the hci-destruct callback.
However, this callback is no longer available so we do not need this
owner field, anymore.  Drivers now call hci_unregister_dev() and they
are done with the object.

Subject: [PATCH 1789/6423] Bluetooth: Correctly take hci_dev->dev refcount

The hci_dev->dev device structure has an internal refcount. This
refcount is used to protect the whole hci_dev object. However, we
currently do not use it.  Therefore, if someone calls hci_free_dev() we
currently immediately destroy the hci_dev object because we never took
the device refcount.

This even happens if the hci_dev->refcnt is not 0. In fact, the
hci_dev->refcnt is totally useless in its current state. Therefore, we
simply remove hci_dev->refcnt and instead use hci_dev->dev refcnt.

This fixes all the symptoms and also correctly integrates the device
structure into our bluetooth bus system.

From dc946bd86f725c42c3ab1caf9966d29f5b364fea Mon Sep 17 00:00:00 2001
From: David Herrmann <dh.herrmann@googlemail.com>
Date: Sat, 7 Jan 2012 15:47:24 +0100
Subject: [PATCH 1790/6423] Bluetooth: Remove __hci_dev_put/hold

Since we remove the owner field of hci_dev hci_dev_put and __hci_dev_put
do the same so we can merge them into one function. Same for
hci_dev_hold and __hci_dev_hold.

Subject: [PATCH 1792/6423] Bluetooth: Move mgmt related flags from hdev->flags
 to hdev->dev_flags

There's no point in exposing these to user-space (which is what happens
to everything in hdev->flags) so move them to dev_flags instead.

Subject: [PATCH 1794/6423] Bluetooth: Sort to-be-resolved devices by RSSI
 during discovery

This patch makes sure that devices with stronger signal (RSSI closer to
0) are sorted first in the resolve list and will therefore get their
names resolved first during device discovery. Since it's more likely
that the device the user is trying to discover has a strong signal due
to its proximity this ensures that the user gets the "device found"
event for it more quickly.

Subject: [PATCH 1797/6423] Bluetooth: Set P-bit for SREJ frame only if there
 are I-frames to ack

SREJ frame with P-bit set acknowledges I-frames numbered up to
(ReqSeq - 1). With this patch P-bit in SREJ is set only when there are
some I-frames to ack.

This fixes ambiguous situation when lost of I-frame with TxSeq=0 would
result in sending SREJ acking all previous I-frames.
Consider following scenario:
TxWindow=3

HostA: sent I-frame TxSeq=0
HostA: sent I-frame TxSeq=1
HostA: sent I-frame TxSeq=2
HostB: missed I-frame TxSeq=0
HostB: received I-frame TxSeq=1
HostB: sent SREJ ReqSeq=0 Pbit=1
HostA: received SREJ ReqSeq=0 Pbit=1   <- All I-frames acked or not?

Subject: [PATCH 1798/6423] Bluetooth: Clear ack_timer when sending ack

ack_timer should be cleared when sending ACK to avoid acking I-frames
twice.

This commit introduces helper function (only send ack, not clearing
timer) which is used by l2cap_send_ack and l2cap_ack_timeout. This is
to avoid clearing ack timer in timer function.

Subject: [PATCH 1799/6423] Bluetooth: Don't send RNR immediately when entering
 local busy

There is no need to send RNR immediately when entring local busy.
Also upper layer might clear local busy condition before ack timer
expires saving few cycles for sending RNR.

This also prevents sending two RNRs in some cases where sending one
would be enough i.e received N I-frame can trigger local busy
(sending RNR acking up to N-1 I-frame) and later sending ack (RNR
acking up to N I-frame).

This was affecting TC_ERM_BV_07_C and TC_ERM_BV_22_C with some non
default channel parameters (tx window and receiving buffer sizes).

Subject: [PATCH 1803/6423] Bluetooth: Add 'eir_len' param to
 mgmt_device_found()

This patch adds a new parameter to mgmt_device_found() to inform
the length of 'eir' pointer.

EIR data from LE advertising report event doesn't have a fixed length
as EIR data from extended inquiry result event does. We needed to
change mgmt_device_found() so it copies 'eir_len' bytes instead of
HCI_MAX_EIR_LENGTH.

 mgmt_ev_device_found

This patch add a two byte eir_len parameter mgmt_ev_device_found. Since
it's unlikely that the data will in the short term be much bigger than
conventional EIR lengths just use a small stack based buffer for now to
avoid dynamic memory allocation & freeing.

Subject: [PATCH 1808/6423] Bluetooth: Rename eir_has_complete_name to
 eir_has_data_type

This allows for other uses such as checking for an embedded class of
device value in order to decide whether to append the class or not.

Subject: [PATCH 1812/6423] Bluetooth: Rename conn->pend to conn->flags

These flags can and will be used for more general purpose values than
just pending state transitions so the more common name "flags" makes
more sense than "pend".

Subject: [PATCH 1813/6423] Bluetooth: Convert hdev->out to a bool type

The hdev->out variable is essentially a boolean so the type 'bool' makes
more sense than u8.

Subject: [PATCH 1814/6423] Bluetooth: Update device_connected and device_found
 events to latest API

This patch updates mgmt_ev_device_connected and mgmt_ev_device found to
include an EIR-encoded remote name and class whenever possible. With
this addition the mgmt_ev_remote_name event becomes unnecessary and can
be removed. Since the connected event doesn't map to hci_conn_complete
anymore a HCI_CONN_MGMT_CONNECTED flag is added to track when mgmt has
been notified about a connection.

Subject: [PATCH 1815/6423] Bluetooth: Merge boolean members of struct hci_conn
 into flags

Now that the flags member of struct hci_conn is supposed to accommodate
any boolean type values we can easily merge all boolean members into it.

Subject: [PATCH 1816/6423] Bluetooth: Convert hdev->ssp_mode to a flag

The ssp_mode is essentially just a boolean so it's more appropriate to
have it simply as a flag in hdev->dev_flags.

Subject: [PATCH 1817/6423] Bluetooth: Add a convenience function to check for
 SSP enabled

It's a very common test to see if both the local and the remote device
have SSP enabled. By creating a simple function to test this we can
shorten many if-statements in the code.

Subject: [PATCH 1819/6423] Bluetooth: silence lockdep warning

Since bluetooth uses multiple protocols types, to avoid lockdep
warnings, we need to use different lockdep classes (one for each
protocol type).

This is already done in bt_sock_create but it misses a couple of cases
when new connections are created. This patch corrects that to fix the
following warning:

It is not used outside of l2cap_core.c. Also l2cap_ertm_data_rcv is
only used after it is defined so there is no need for forward declaration.

Subject: [PATCH 1824/6423] Bluetooth: Fix potential deadlock

We don't need to use the _sync variant in hci_conn_hold and
hci_conn_put to cancel conn->disc_work delayed work. This way
we avoid potential deadlocks like this one reported by lockdep.

Subject: [PATCH 1826/6423] Bluetooth: Remove usage of __cancel_delayed_work()

__cancel_delayed_work() is being used in some paths where we cannot
sleep waiting for the delayed work to finish. However, that function
might return while the timer is running and the work will be queued
again. Replace the calls with safer cancel_delayed_work() version
which spins until the timer handler finishes on other CPUs and
cancels the delayed work.

This defines two new messages, one event that will inform

will allow userspace to load LTKs into the kernel.

Besides the information necessary for the restablishement of
the secure link, we added some extra information: "authenticated"
that informs if the key can be used to establish an authenticated
link, and "master" that informs the role in that the key should
be used.

This issue has been brought up earlier here:

https://lkml.org/lkml/2011/5/21/127

The issue appears to be the rfcomm_session_put in rfcomm_recv_ua. This
operation doesn't seem be to required as for the non-initiator case we
have the rfcomm_process_rx doing an explicit put and in the initiator
case the last dlc_unlink will drive the reference counter to 0.

There have been several attempts to fix these issue:

6c2718d Bluetooth: Do not call rfcomm_session_put() for RFCOMM UA on closed socket
683d949 Bluetooth: Never deallocate a session when some DLC points to it

but AFAICS they do not fix the issue just make it harder to reproduce.

Subject: [PATCH 1834/6423] Bluetooth: Fix l2cap conn failures for ssp devices

Commit 330605423c fixed l2cap conn establishment for non-ssp remote
devices by not setting HCI_CONN_ENCRYPT_PEND every time conn security
is tested (which was always returning failure on any subsequent
security checks).

However, this broke l2cap conn establishment for ssp remote devices
when an ACL link was already established at SDP-level security. This
fix ensures that encryption must be pending whenever authentication
is also pending.

From b899efaf9b26cadb084752862490b4fc44bc3169 Mon Sep 17 00:00:00 2001
From: Vinicius Costa Gomes <vinicius.gomes@openbossa.org>
Date: Thu, 2 Feb 2012 21:08:00 -0300
Subject: [PATCH 1842/6423] Bluetooth: Add new structures for handling SMP Long
 Term Keys

This includes a new list for storing the keys and a new structure used
to represent each key.

Some notes: authenticated is used to identify that the key may be used
to setup a HIGH security link. As the same list is used to store both
the STK's and the LTK's the type field is used so we can separate
between those two types of keys and if the key should be used when
in the master or slave role.

Subject: [PATCH 1843/6423] Bluetooth: Use the updated key structures for
 handling LTKs

This updates all the users of the older way, that was using the
link_keys list to store the SMP keys, to use the new way.

This includes defining new types for the keys, we have a type for each
combination of STK/LTK and Master/Slave.

Subject: [PATCH 1847/6423] Bluetooth: Add support for notifying userspace of
 new LTK's

If we want to have proper pairing support over LE we need to
inform userspace that a new LTK is available, so userspace
can store that key permanently.

Send MGMT Discovering events once LE scan starts/stops so the

This way, we also keep the same behavior of inquiry which sends MGMT

Subject: [PATCH 1853/6423] Bluetooth: Add hci_do_le_scan()

This patch adds to hci_core the hci_do_le_scan function which
should be used to scan LE devices.

In order to enable LE scan, hci_do_le_scan() sends commands (Set
LE Scan Parameters and Set LE Scan Enable) to the controller and
waits for its results. If commands were executed successfully a
delayed work is scheduled to disable the ongoing scanning after
some amount of time. This function blocks.

Subject: [PATCH 1854/6423] Bluetooth: Add hci_le_scan()

We are not supposed to block in start_discovery() because
start_discovery code is running in write() syscall context
and this would block the write operation on the mgmt socket.
This way, we cannot directly call hci_do_le_scan() to scan
LE devices in start_discovery(). To overcome this issue a
derefered work (hdev->le_scan) was created so we can properly
call hci_do_le_scan().

The helper function hci_le_scan() simply set LE scan parameters
and queue hdev->le_scan work. The work is queued on system_long_wq
since it can sleep for a few seconds in the worst case (timeout).

As only pending I-Frames are considered as acknowledgement, this could
lead to situation when no ACK was sent in __l2cap_send_ack (if only
already transmitted I-Frames were retransmitted).

Subject: [PATCH 1863/6423] Bluetooth: Fix double acking I-Frames when sending
 pending I-Frames

Pending I-Frame(s) are considered as acknowledgement. To void double
acking (via I-Frame and later via RR) clear ack timer when sending
first pending I-Frame.

Subject: [PATCH 1864/6423] Bluetooth: Update and rename mgmt_remove_keys to
 mgmt_unpair_device

This patch renames the mgmt_remove_keys command to mgmt_unpair_device
and updates its parameters to match the latest API (specifically, it
adds an address type parameter to the command and its response).

Subject: [PATCH 1867/6423] Bluetooth: Add address type to Out Of Band mgmt
 messages

This patch updates the implementation for these mgmt to be up to date
with the latest API specification. Right now the address type isn't
actually used for anything but that might change in the future.

Subject: [PATCH 1870/6423] Bluetooth: Fix mgmt_unpair_device command status

The default response status to unpair_device should be set as 0 instead
of a generic failure value. When disconnection is not needed (i.e. we
can reply imediately) we should return success and not failure.

Subject: [PATCH 1871/6423] Bluetooth: Add Device Unpaired mgmt event

This patch add a new Device Unpaired mgmt event. This will be sent to
all mgmt sockets except the one that requested unpairing (that socket
will get a command complete instead). The event is also reserved for
future SMP updates where a remote device will be able to request pairing
revocation from us.

Subject: [PATCH 1872/6423] Bluetooth: Introduce to_hci_dev()

We currently use dev_set_drvdata to keep a pointer to ourself. This
doesn't make sense as we are the bus and not a driver. Therefore,
introduce to_hci_dev() so we can get a struct hci_dev pointer from a
struct device pointer.

dev_set/get_drvdata() is reserved for drivers that provide a device and
not for the bus using the device. The bus can use simple pointer
arithmetic to retrieve its private data.

From 155961e8001719af6d87cbcc961111e8ce477843 Mon Sep 17 00:00:00 2001
From: David Herrmann <dh.herrmann@googlemail.com>
Date: Thu, 9 Feb 2012 21:58:32 +0100
Subject: [PATCH 1873/6423] Bluetooth: Remove hci_dev->driver_data

The linux device model provides dev_set/get_drvdata so we can use this
to save private driver data.
This also removes several unnecessary casts.

Subject: [PATCH 1874/6423] Bluetooth: Introduce to_hci_conn

This avoids using the dev_set/get_drvdata() functions to retrieve a
pointer to our own structure. We can use simple pointer arithmetic here.
The drvdata field is actually not needed by any other code-path but this
makes the code more consistent with hci_dev.

Subject: [PATCH 1877/6423] PM / QoS: unconditionally build the feature

The PM QoS feature originally didn't depend on CONFIG_PM, which was
mistakenly changed by commit e8db0be1245de16a6cc6365506abc392c3c212d4

    PM QoS: Move and rename the implementation files

Later, commit d020283dc694c9ec31b410f522252f7a8397e67d

    PM / QoS: CPU C-state breakage with PM Qos change

partially fixed that by introducing a static inline definition of
pm_qos_request(), but that still didn't allow user space to use
the PM QoS interface if CONFIG_PM was unset (which had been possible
before).  For this reason, remove the dependency of PM QoS on
CONFIG_PM to make it work (as intended) with CONFIG_PM unset.

[rjw: Replaced the original changelog with a new one.]

Subject: [PATCH 1879/6423] PM / Sleep: Do not check wakeup too often in
 try_to_freeze_tasks()

Use the observation that it is more efficient to check the wakeup
variable once before the loop reporting tasks that were not
frozen in try_to_freeze_tasks() than to do that in every step of that
loop.

Subject: [PATCH 1880/6423] PM / Sleep: Remove unnecessary label from
 suspend_freeze_processes()

The Finish label in suspend_freeze_processes() is in fact unnecessary
and makes the function look more complicated than it really is, so
remove that label (along with a few empty lines).

Subject: [PATCH 1881/6423] drm/i915: Don't lock panel registers when
 downclocking

This patch replaces the locking from the downclock routines with an assert
to ensure the registers are indeed unlocked. Without this patch, pre-SNB
devices would lock the registers when downclocking which would cause a
WARNING on suspend/resume with downclocking enabled.

Note: To hit this bug, you need to have lvds downclocking enabled.

Subject: [PATCH 1882/6423] Staging: hv: storvsc: Move the storage driver out
 of the staging area

The storage driver (storvsc_drv.c) handles all block storage devices
assigned to Linux guests hosted on Hyper-V. This driver has been in the
staging tree for a while and this patch moves it out of the staging area.

James was willing to apply this patch during the 3.3-rc phase and a decision
was taken to defer this to 3.4 since Greg had queued up a bunch of storvsc
patches for 3.4. Now that Greg has applied all of the pending storvsc patches,
I am sending this patch to move this driver out of staging. Based on James'
recommendation, this patch gets rid of the unneeded files in the staging/hv
directory.

Subject: [PATCH 1887/6423] e1000e: cleanup: use goto for common work needed by
 multiple exit points

There are two exit points of e1000e_write_nvm_spi() which require the
nvm->ops.release() function pointer called just before exiting.
Consolidate the two duplicate pieces of common work with a goto.  With
this change, the value ret_val will need to be returned instead of 0.

Subject: [PATCH 1888/6423] e1000e: cleanup: rename goto labels to be more
 meaningful

In the following functions, rename the generic 'out' goto label to the more
descriptive 'release' to indicate the type of common work that is done
before exiting the functions.  No functional change, cosmetic only.

Subject: [PATCH 1890/6423] e1000e: potential incorrect return for
 e1000_setup_copper_link_80003es2lan

In the unlikely event that e1000e_setup_copper_link() returns an error,
the returned error code value is not propogated to the caller of
e1000_setup_copper_link_80003es2lan().

Subject: [PATCH 1897/6423] tg3: Move tg3_set_rx_mode

This patch moves __tg3_set_rx_mode above its first use and moves
tg3_set_rx_mode down closer to where the netdev_ops functions should be.

Subject: [PATCH 1905/6423] e1000e: potentially incorrect return for
 e1000_set_d3_lplu_state_ich8lan

In the unlikely event that e1e_wphy() returns an error, the returned error
code is not propogated to the caller of e1000_set_d3_lplu_state_ich8lan().
With this change, there is a rare possibility that ret_val might not get
set so it must be initialized.

ret_val gets initialized to -E1000_ERR_NVM and never set differently, so
get rid of it and just return -E1000_ERR_NVM.

Subject: [PATCH 1913/6423] e1000e: cleanup goto statements to exit points
 without common work

Per ./Documentation/CodingStyle, goto statements are acceptable for the
centralized exiting of functions when there are multiple exit points which
share common work such as cleanup.  When no common work is required for
multiple exit points, the function should just return at these exit points
instead of doing an unnecessary jump to a centralized return.  This patch
cleans up the inappropriate use of goto statements, and removes unnecessary
variables (or move to a smaller scope) where possible as a result of the
cleanups.

Subject: [PATCH 1916/6423] XFS: xfs_trans_add_item() - don't assign in
 ASSERT() when compare is intended

It looks to me like the two ASSERT()s in xfs_trans_add_item() really
want to do a compare (==) rather than assignment (=).
This patch changes it from the latter to the former.

Subject: [PATCH 1918/6423] x86/cpu: Clean up modalias feature matching

We currently include commas on both sides of the feature ID in a
modalias, but this prevents the lowest numbered feature of a CPU from
being matched.  Since all feature IDs have the same length, we do not
need to worry about substring matches, so omit commas from the
modalias entirely.

Avoid generating multiple adjacent wildcards when there is no
feature ID to match.

Commit b66b8b9a4a79087dde1b358a016e5c8739ccf186 ('intel-idle: convert
to x86_cpu_id auto probing') put two entries for model 0x2f
(Westmere-EX Xeon) in the device ID table and left out model 0x2e
(Nehalem-EX Xeon).

Subject: [PATCH 1922/6423] sfc: Skip RX end-of-batch work on channels without
 an RX queue

The code in efx_process_channel() to update the RX queue after each
batch of RX completions works out as a no-op on a TX-only channel
where the RX queue structure is set to all-zeroes, but
(1) efx_channel_get_rx_queue() will BUG() if DEBUG is defined, and
(2) it's a waste of time.

Subject: [PATCH 1923/6423] sfc: Do not retry hardware probe if it schedules a
 reset

If efx_pci_probe_main() schedules an INVISIBLE or ALL reset (but
nothing more drastic), we retry it up to 5 times.  So far as I'm
aware, this was a workaround for bugs in Falcon A0 which were fixed
in production silicon.  Remove the retry.

Subject: [PATCH 1924/6423] sfc: Replace some literal constants with
 EFX_PAGE_SIZE/EFX_BUF_SIZE

The 'page size' for PCIe DMA, i.e. the alignment of boundaries at
which DMA must be broken, is 4KB.  Name this value as EFX_PAGE_SIZE
and use it in efx_max_tx_len().  Redefine EFX_BUF_SIZE as
EFX_PAGE_SIZE since its value is also a result of that requirement,
and use it in efx_init_special_buffer().

Subject: [PATCH 1929/6423] tg3: Disable new DMA engine for 57766

A bug was found in the new DMA engine for the 57766.  This patch
disables it, which causes the device to fallback to the old DMA engine.

Subject: [PATCH 1932/6423] tg3: Fix NVRAM page writes on newer devices

On newer devices, the hardware expects the NVRAM address register
to be written only once per NVRAM page.  To do otherwise causes NVRAM
corruption.  This patch fixes the problem.

Subject: [PATCH 1933/6423] tg3: Reduce UMP event collision window

The tg3 driver needs to submit a few phy register values to the UMP
firmware each time the link state changes.  Up until now, the driver
would wait for the previous event to complete, then proceed to gather
data through a series of phy accesses.  Since phy accesses are
relatively slow, it is possible for another thread to attempt to submit
its own event while the UMP code is still construction its message.

This patch seeks to minimize the collision window as much as possible by
preloading the phy data.

Subject: [PATCH 1935/6423] tg3: Remove unused link config code

When tg3 devices are shutdown, the driver uses the
TG3_PHYFLG_IS_LOW_POWER flag to enable a static phy configuration.
Any attempt to use the link configuration variables is dead code.  This
patch removes such code.

Subject: [PATCH 1936/6423] tg3: Remove unneeded link_config.orig_... members

This patch removes the unneeded link_config.orig_* members.  When the
phy is in a low power state, the TG3_PHYFLG_IS_LOW_POWER flag solely
determines how the link is configured.  When the phy is powered back up,
it can resume using the original settings.

For the phylib case, the link configuration still needs to be saved, but
since the phylib maintains its own configuration, we can repurpose the
(unused in this case) tg3 link configuration members.

acpi_size is u32 or u64 depending on architecture. Cast it to
unsigned long and use %lu for printing.

This fix following build warning:

Subject: [PATCH 1948/6423] staging:iio: Add missing event code extract macros

Add macros for extracting whether the event is for a differential channel and

Subject: [PATCH 1949/6423] staging:iio: Add event monitor example application

Add a small evtest like application to monitor events generated by an IIO
device. The application can be used as an example on how to listen for IIO
events and also is usful for testing and debugging device drivers which
generate IIO events.

Subject: [PATCH 1950/6423] staging: zram: Rename module parameter

zram accepts number of devices to be created
as a module parameter. This was renamed from
num_devices to zram_num_devices (without updating
the documentation!) since num_devices was declared
as a non-static global variable, polluting the global
namespace. Now, we declare it as a static variable
and revert back the name change.

The documentation (zram.txt) already mentions
num_devices as the module parameter name.

DRIVER_HALT is a driver state that was originally

Subject: [PATCH 1954/6423] drm/i915: add a "force-dvi" HDMI audio mode

When HDMI-DVI converter is used, it's not only necessary to turn off
audio, but also to disable HDMI_MODE_SELECT and video infoframe. Since
the DVI mode is mainly tied to audio functionality from end user POV,
add a new "force-dvi" audio mode:

	xrandr --output HDMI1 --set audio force-dvi

Note that most users won't need to set this and happily rely on the EDID
based DVI auto detection.

Subject: [PATCH 1955/6423] drm/i915: Fix race condition in accessing GMBUS

GMBUS has several ports and each has it's own corresponding
I2C adpater. When multiple I2C adapters call gmbus_xfer() at
the same time there is a race condition in using the underlying
GMBUS controller. Fixing this by adding a mutex lock when calling
gmbus_xfer().

v2: Moved gmbus_mutex below intel_gmbus and added comments.
Rebased to drm-intel-next-queued.

Signed-off-by: Yufeng Shen <miletus@chromium.org>
[danvet: Shortened the gmbus_mutex comment a bit and add the patch
revision comment to the commit message.]

list.h already provide helpers to find the first entry and to move list

no functional changes.

As discussed during the 2011 V4L-DVB workshop, the API in dvb/video.h should
be replaced by a proper V4L2 API. This patch turns the VIDEO_(TRY_)DECODER_CMD
ioctls into proper V4L2 ioctls.

Subject: [PATCH 1961/6423] [media] v4l2-ctrls: add new controls for MPEG
 decoder devices

As discussed during the 2011 V4L-DVB workshop we want to create a proper V4L2
decoder API that replaces the DVBv5 API that has been used until now.

This adds the four controls necessary to be able to switch ivtv over to this
new API.

Subject: [PATCH 1965/6423] [media] ivtv: add IVTV_IOC_PASSTHROUGH_MODE

With this private ioctl it is possible to use the ivtv decoder without
requiring the dvb/video.h and dvb/audio.h headers.

Eventually support for those DVB APIs will be dropped from ivtv.

Subject: [PATCH 1967/6423] PCI: Fix starting basis for resource requests

pci_revert_fw_address() is used to reinstate a PCI device's original
FW-assigned BIOS BAR value(s) if normal resource assignment fails.

When attempting to reinstate an address, the point within the resource
tree from which to attempt the new resource request should be the parent
resource corresponding to the device, not the base of the resource tree
(ioport_resource or iomem_resource).  For PCI devices this would
typically be the resource corresponding to the upstream PCI host bridge
or P2P bridge aperture.

This patch sets the point within the resource tree to attempt a new
resource assignment request to the PCI device's parent resource and only
if that fails does it fall back to the base ioport_resource or
iomem_resource.

Subject: [PATCH 1968/6423] x86/PCI: Infrastructure to maintain a list of
 FW-assigned BIOS BAR values

Commit 58c84eda075 introduced functionality to try and reinstate the
original BIOS BAR addresses of a PCI device when normal resource
assignment attempts fail.  To keep track of the BIOS BAR addresses,
struct pci_dev was augmented with an array to hold the BAR addresses
of the PCI device: 'resource_size_t fw_addr[DEVICE_COUNT_RESOURCE]'.

The reinstatement of BAR addresses is an uncommon event leaving the
'fw_addr' array unused under normal circumstances.  This functionality
is also currently architecture specific with an implementation limited
to x86.  As the use of struct pci_dev is so prevalent, having the
'fw_addr' array residing within such seems somewhat wasteful.

This patch introduces a stand alone data structure and interfacing
routines for maintaining a list of FW-assigned BIOS BAR value entries.

Subject: [PATCH 1970/6423] PCI: Can continually add funcs after adding func0

Boot up a KVM guest, and hotplug multifunction
devices(func1,func2,func0,func3) to guest.

for i in 1 2 0 3;do
qemu-img create /tmp/resize$i.qcow2 1G -f qcow2
(qemu) drive_add 0x11.$i id=drv11$i,if=none,file=/tmp/resize$i.qcow2
(qemu) device_add virtio-blk-pci,id=dev11$i,drive=drv11$i,addr=0x11.$i,multifunction=on
done

In linux kernel, when func0 of the slot is hot-added, the whole
slot will be marked as 'enabled', then driver will ignore other new
hotadded funcs.
But in Win7 & WinXP, we can continaully add other funcs after adding
func0, all funcs will be added in guest.

drivers/pci/hotplug/acpiphp_glue.c:
static int acpiphp_check_bridge(struct acpiphp_bridge *bridge)
{
....
        for (slot = bridge->slots; slot; slot = slot->next) {
                if (slot->flags & SLOT_ENABLED) {
                        acpiphp_disable_slot()
                else
                        acpiphp_enable_slot()
....                              |
}                                 v
                            enable_device()
                                  |
                                  v
        //only don't enable slot if func0 is not added
	list_for_each_entry(func, &slot->funcs, sibling) {
               ...
        }
       slot->flags |= SLOT_ENABLED; //mark slot to 'enabled'

This patch just make pci driver can continaully add funcs after adding
func 0. Only mark slot to 'enabled' when all funcs are added.

For pci multifunction hotplug, we can add functions one by one(func 0 is
necessary), and all functions will be removed in one time.

Subject: [PATCH 1972/6423] PCI: Introduce __pci_reset_function_locked to be
 used when holding device_lock.

The use case of this is when a driver wants to call FLR when a device
is attached to it using the SysFS "bind" or "unbind" functionality.

The call chain when a user does "bind" looks as so:

 echo "0000:01.07.0" > /sys/bus/pci/drivers/XXXX/bind

and ends up calling:
  driver_bind:
    device_lock(dev);  <=== TAKES LOCK
    XXXX_probe:
         .. pci_enable_device()
         ...__pci_reset_function(), which calls
                 pci_dev_reset(dev, 0):
                        if (!0) {
                                device_lock(dev) <==== DEADLOCK

The __pci_reset_function_locked function allows the the drivers
'probe' function to call the "pci_reset_function" while still holding
the driver mutex lock.

Subject: [PATCH 1973/6423] xen/pciback: Support pci_reset_function, aka FLR or
 D3 support.

We use the __pci_reset_function_locked to perform the action.
Also on attaching ("bind") and detaching ("unbind") we save and
restore the configuration states. When the device is disconnected
from a guest we use the "pci_reset_function" to also reset the
device before being passed to another guest.

Subject: [PATCH 1974/6423] x86/PCI: don't fall back to defaults if _CRS has no
 apertures

Host bridges that lead to things like the Uncore need not have any
I/O port or MMIO apertures.  For example, in this case:

    ACPI: PCI Root Bridge [UNC1] (domain 0000 [bus ff])
    PCI: root bus ff: using default resources
    PCI host bridge to bus 0000:ff
    pci_bus 0000:ff: root bus resource [io  0x0000-0xffff]
    pci_bus 0000:ff: root bus resource [mem 0x00000000-0x3fffffffffff]

we should not pretend those default resources are available on bus ff.

Subject: [PATCH 1976/6423] PCI : Calculate right add_size

During debug of one SRIOV enabled hotplug device, we found found that
add_size is not passed properly.

The device has devices under two level bridges:

 +-[0000:80]-+-00.0-[81-8f]--
 |           +-01.0-[90-9f]--
 |           +-02.0-[a0-af]----00.0-[a1-a3]--+-02.0-[a2]--+-00.0  Oracle Corporation Device
 |           |                               \-03.0-[a3]--+-00.0  Oracle Corporation Device

Which means later the parent bridge will not try to add a big enough range:

[  557.455077] pci 0000:a0:00.0: BAR 14: assigned [mem 0xf9000000-0xf93fffff]
[  557.461974] pci 0000:a0:00.0: BAR 15: assigned [mem 0xf6000000-0xf61fffff pref]
[  557.469340] pci 0000:a1:02.0: BAR 14: assigned [mem 0xf9000000-0xf91fffff]
[  557.476231] pci 0000:a1:02.0: BAR 15: assigned [mem 0xf6000000-0xf60fffff pref]
[  557.483582] pci 0000:a1:03.0: BAR 14: assigned [mem 0xf9200000-0xf93fffff]
[  557.490468] pci 0000:a1:03.0: BAR 15: assigned [mem 0xf6100000-0xf61fffff pref]
[  557.497833] pci 0000:a1:03.0: BAR 14: can't assign mem (size 0x200000)
[  557.504378] pci 0000:a1:03.0: failed to add optional resources res=[mem 0xf9200000-0xf93fffff]
[  557.513026] pci 0000:a1:02.0: BAR 14: can't assign mem (size 0x200000)
[  557.519578] pci 0000:a1:02.0: failed to add optional resources res=[mem 0xf9000000-0xf91fffff]

It turns out we did not calculate size1 properly.

static resource_size_t calculate_memsize(resource_size_t size,
                resource_size_t min_size,
                resource_size_t size1,
                resource_size_t old_size,
                resource_size_t align)
{
        if (size < min_size)
                size = min_size;
        if (old_size == 1 )
                old_size = 0;
        if (size < old_size)
                size = old_size;
        size = ALIGN(size + size1, align);
        return size;
}

We should not pass add_size with min_size in calculate_memsize since
that will make add_size not contribute final add_size.

So just pass add_size with size1 to calculate_memsize().

With this change, we should have chance to remove extra addon in
pci_reassign_resource.

Subject: [PATCH 1979/6423] PCI: try to assign required+option size first

We found reassignment can not find a range for one resource, even if the
total available range is large enough.

bridge b1:02.0 will need 2M+3M
bridge b1:03.0 will need 2M+3M

so bridge b0:00.0 will get assigned: 4M : [f8000000-f83fffff]
   later is reassigned to 10M : [f8000000-f9ffffff]

b1:02.0 is assigned to 2M : [f8000000-f81fffff]

Thus b2:00.0 BAR 9 does not get assigned...

root cause:
b1:02.0 can not be added more range, because b1:03.0 is just after it;
no space between the required ranges.

Solution:
Try to assign required + optional all together at first, and if that
fails, try again with just the required resources.

-v2: seperate add_to_list change() to another patch according to Jesse.
     seperate get_res_add_size() moving to another patch according to Jesse.
     add !realloc_head->next check if the list is empty to bail early
     according to Jesse.

Subject: [PATCH 1981/6423] PCI: Make rescan bus increase bridge resource size
 if needed

Current rescan will not touch bridge MMIO and IO.

Try to reuse pci_assign_unassigned_bridge_resources(bridge) to update bridge
resources, if child devices need more resources.

Only do that for bridges whose children are all removed already; i.e. don't
release resources that could already be in use by drivers on child devices.

Subject: [PATCH 1982/6423] PCI: Make pci_rescan_bus handle add_list

This allows us to allocate resources to hotplug bridges during
remove/rescan.

We need to move the function to setup-bus.c so it can use
__pci_bus_size_bridges and __pci_bus_assign_resources directly to take
the add_list resource tracking list.

Subject: [PATCH 1983/6423] PCI: make re-allocation try harder by reassigning
 ranges higher in the heirarchy

On a system with devices that support SRIOV connected to a pcie switch
to pcie root port:

 +-[0000:80]-+-00.0-[81-8f]--
 |           +-01.0-[90-9f]--
 |           +-02.0-[a0-af]----00.0-[a1-a3]--+-02.0-[a2]--+-00.0 Oracle Corporation Device 207a
 |           |                               \-03.0-[a3]--+-00.0 Oracle Corporation Device 207a
 |           +-02.2-[b0-bf]----00.0-[b1-b3]--+-02.0-[b2]--+-00.0 Oracle Corporation Device 207a
 |           |                               \-03.0-[b3]--+-00.0 Oracle Corporation Device 207a

When the BIOS does not assign resources for SRIOV BARs, kernel pci
reallocation only goes up one bridge and then gives up, failing to to
get resources for all sSRIOV BARs, even though the range is large enough
in the peer root bus.

Specifically, only the bridge at the a1:02.0 level has its resources
cleared and reallocated.  The kernel does not go up to clear the bridge
at the 80:02.0 level.

To make it go to upper levels, during retry, we need to treat "good to have"
resources as "must have".

Only on the last try will we treat good to have resources as optional.
At that time, parent bridge resources will already have been released so
we'll have a chance to get everything assigned with must_have plus
good_to_have for all child devices.

From 764242a0aec69e10b8dc0f4f0303a6800b09cf45 Mon Sep 17 00:00:00 2001
From: Yinghai Lu <yinghai@kernel.org>
Date: Sat, 21 Jan 2012 02:08:28 -0800
Subject: [PATCH 1987/6423] PCI: Merge pci_dev_resource_x and pci_dev_resource

pci_dev_resource_x is a superset of pci_dev_resource and they're just
temp structs used during resource reallocation.

pci_dev_resource usage is quite limted.

So just use pci_dev_resource_x, and rename it as new pci_dev_resource.

-v2: According to Linus, Separate free_list change to another patch

Subject: [PATCH 1988/6423] PCI: Rename dev_res_x to add_res or fail_res

Linus says don't use dev_res_x because it doesn't communicate anything
about usage.  Rename them to add_res or fail_res etc according to
context.

Subject: [PATCH 1992/6423] PCI: make sriov work with hotplug remove

When hot removing a pci express module that has a pcie switch and supports
SRIOV, we got:

root complex: 80:02.2
pci express modules: have pcie switch and are listed as b0:00.0, b1:02.0 and b1:03.0.
end devices  are b2:00.0 and b3.00.0.
VFs are: b2:00.1,... b2:00.3, and b3:00.1,...,b3:00.3

Root cause: when doing pci_stop_bus_device() with phys fn, it will stop
virt fn and remove the fn, so
	list_for_each_safe(l, n, &bus->devices)
will have problem to refer freed n that is pointed to vf entry.

Solution is just replacing list_for_each_safe() with
list_for_each_prev_safe().  This will make sure we can get valid n pointer
to PF instead of the freed VF pointer (because newly added devices are
inserted to the bus->devices list tail).

During reviewing the patch, Bjorn said:
|   The PCI hot-remove path calls pci_stop_bus_devices() via
|   pci_remove_bus_device().
|
|   pci_stop_bus_devices() traverses the bus->devices list (point A below),
|   stopping each device in turn, which calls the driver remove() method.  When
|   the device is an SR-IOV PF, the driver calls pci_disable_sriov(), which
|   also uses pci_remove_bus_device() to remove the VF devices from the
|   bus->devices list (point B).
|
|       pci_remove_bus_device
|         pci_stop_bus_device
|           pci_stop_bus_devices(subordinate)
|             list_for_each(bus->devices)             <-- A
|               pci_stop_bus_device(PF)
|                 ...
|                   driver->remove
|                     pci_disable_sriov
|                       ...
|                         pci_remove_bus_device(VF)
|                             <remove from bus_list>  <-- B
|
|   At B, we're changing the same list we're iterating through at A, so when
|   the driver remove() method returns, the pci_stop_bus_devices() iterator has
|   a pointer to a list entry that has already been freed.

Discussion thread can be found : https://lkml.org/lkml/2011/10/15/141
				 https://lkml.org/lkml/2012/1/23/360

-v5: According to Linus to make remove more robust, Change to
     list_for_each_prev_safe instead. That is more reasonable, because
     those devices are added to tail of the list before.

Try to access the pci conf of a pci device that is supposed to show up
in 1s.  If we can read back a valid vendor/device id, we can return
early.

Related discussion could be found:
	https://lkml.org/lkml/2011/12/6/339

-v2: seperate code to pci_bus_read_dev_vendor_id() from pci_scan_device()
    and reuse it from pciehp code. Suggested by Matthew Wilcox.
-v3: According to Kenj, don't use array in stack, and don't wait too long
    for crs, also return fail status if not found.
    Also separate pci_bus_dev_read_vendor_id() change to another patch.

Subject: [PATCH 1998/6423] PCI: pciehp: Disable/enable link during slot power
 off/on

On a system with a repeater on the system board to support gen2 hotplug,
we found that when an ExpressModule is removed from some slots,
/var/log/messages will be full of "card present/not present" warnings.

It turns out the root complex is continually trying to train the link to
the repeater because the repeater has not been reset.

This patch will disable the link at removal time to allow the repeater
to be reset properly.  This also prevents a potential AER message at
removal time.

Also, when testing hotplug on a system under development, we found if we
boot the system without an EM installed, and later hot-add an EM, it
does not work with Linux, but another OS is ok.  The root cause is that
BIOS left link disabled when slot was empty at boot time, and other OS
is modifying the link disable bit in link ctrl during power on/off.

So we should do the same thing to disable/enable link during power off/on.

-v2: check link DLLA bit instead of 100ms waiting.
     Separate link disable/enable functions to another patch.

On some OEM systems, pci_restore_state() is called while FLR has not yet
completed.  As a result, PCI BAR register restore is not successful.  This fix
reads back the restored value and compares it with saved value and re-tries 10
times before giving up.

Subject: [PATCH 2001/6423] PCI: Annotate PCI quirks in initcall_debug style

While diagnosing some boot time issues on a platform, all that I
could see in the bootgraph/dmesg was that the system was spending
a lot of time in applying one or more PCI quirks... which
was virtually undebuggable.

This patch adds printk's in "initcall_debug" style to the dmesg,
which are added when the user asks for the initcall_debug
(the nr one tool to use when debugging boot hangs or boot time issues)
kernel command line option.

v2: add #includes so quirks can build on non-x86

Subject: [PATCH 2002/6423] PCI: Add quirk for still enabled interrupts on
 Intel Sandy Bridge GPUs

Some BIOS implementations leave the Intel GPU interrupts enabled,
even though no one is handling them (f.e. i915 driver is never loaded).
Additionally the interrupt destination is not set up properly
and the interrupt ends up -somewhere-.

These spurious interrupts are "sticky" and the kernel disables
the (shared) interrupt line after 100.000+ generated interrupts.

Fix it by disabling the still enabled interrupts.
This resolves crashes often seen on monitor unplug.

Tested on the following boards:
- Intel DH61CR: Affected
- Intel DH67BL: Affected
- Intel S1200KP server board: Affected
- Asus P8H61-M LE: Affected, but system does not crash.
  Probably the IRQ ends up somewhere unnoticed.

According to reports on the net, the Intel DH61WW board is also affected.

Many thanks to Jesse Barnes from Intel for helping
with the register configuration and to Intel in general
for providing public hardware documentation.

Subject: [PATCH 2004/6423] [media] v4l2: standardize log start/end message

For drivers that properly use the v4l2 framework (i.e. set v4l2_dev in the
video_device struct), the start and end messages of VIDIOC_LOG_STATUS are
now generated automatically. People tended to forget these, but the v4l2-ctl
tool scans for these messages, and it also makes it easier to read the status
output in the kernel log.

The cx18, ivtv and bttv drivers were changed since they no longer need to
log these start/end messages.

In saa7164 two empty log_status functions were removed.

Also added a helper function to v4l2-ctrl.c that can be used as the
vidioc_log_status callback if all you need to do is to log the current control
values. This is now used by pwc and vivi.

Subject: [PATCH 2006/6423] [media] v4l2-ctrls: add helper functions for
 control events

Many drivers just support control events, and most radio drivers just need
to poll for control events. Add some functions to simplify those jobs.

Detect iTPMs through the vendor ID on the hardware interface and only
probe the device if the manufacturer is found to be Intel. This
obsoletes a previously added delay necessary for some TPMs but not iTPMs.

Commit 3321c07ae5068568cd61ac9f4ba749006a7185c9 correctly clears the TPM
buffer if the user specified read length is >= the TPM buffer length. However,
if the user specified read length is < the TPM buffer length, then part of the
TPM buffer is left uncleared.

Subject: [PATCH 2013/6423] [media] it913x v1.25 support different for remotes

Support for different types of remote.

ITE remotes share common device IDs with differently assigned keys.

Two versions of remote maps have been created there are likely to be more.
v1 for all other IDs
v2 for USB_PID_ITETECH_IT9135_9005.

This patch also separates the configuration parts from it913x_identify_state function.

TODO
remotes for HID interfaces.

Subject: [PATCH 2015/6423] [media] radio-isa: add framework for ISA radio
 drivers

We have quite a few ISA radio drivers, which are all very similar.

This framework makes it possible to reduce the code size of those drivers
and makes it much easier to keep them up to date with the latest V4L2 API
developments.

Drivers rewritten to use this framework fully pass the v4l2-compliance tests
and are properly using the ISA bus (so they can be found under /sys/bus/isa).

It is now also possible to support multiple cards using the same driver
(tested with two radio-gemtek cards).

 	  To compile this driver as a module, choose M here: the
 	  module will be called radio-rtrack2.

-	  <file:Documentation/video4linux/API.html>.
+	  Note: this driver hasn't been tested since a long time due to lack
+	  of hardware. If you have this hardware, then please contact the
+	  linux-media mailinglist.
 
 	  To compile this driver as a module, choose M here: the
 	  module will be called radio-typhoon.

Subject: [PATCH 2024/6423] mlx4_core: fix buffer overrun

When passing MLX4_UC_STEER=1 it was translated to value 2
after mlx4_QP_ATTACH_wrapper. Therefore in new_steering_entry()
unicast steer entries were added to index 2 of array of size 2.
Fixing this bug by shift right to one position.

Subject: [PATCH 2025/6423] mlx4: fix QP tree trashing

When adding new unicast steer entry, before moving qp to state ready,
actually before calling mlx4_RST2INIT_QP_wrapper(), there were added
a lot of entries with local_qpn=0 into radix tree.
This fact impacted the get_res() function and proper functioning
of resource tracker in addition to adding trash entries into radix tree.

 gid

mlx4_uc_steer_add/release() should not add MLX4_UC_STEER flag to gid.
It is added in mlx4_unicast_attach/detach().

Subject: [PATCH 2030/6423] mlx4: add unicast steering entries to
 resource_tracker

Add unicast steering entries to resource tracker.
Do qp_detach also for these entries when VF doesn't shut down gracefully.
Otherwise there is leakage of these resources, since they are not tracked.

Subject: [PATCH 2033/6423] [media] dvb-core: fix DVBFE_ALGO_HW retune bug

Commit 7e07222 breaks DVBFE_ALGO_HW tuning after a retune is requested,
which causes bad tuning on my TBS 6920.

7e0722215a510921cbb73ab4c37477d4dcb91bf8 [media] dvb-core: Don't pass DVBv3 parameters on tune() fops

Although re_tune is set to true when FESTATE_RETUNE occurs, it is never
set back to false which the old code used to do when !FESTATE_RETUNE.

This patch sets re_tune to false if !(state & FESTATE_RETUNE).

Subject: [PATCH 2035/6423] [media] xc5000: allow drivers to set desired
 firmware in xc5000_attach

newer versions of the xc5000 silicon require newer firmware
while remaining 100% driver compatible.  original versions
of the xc5000a continue to use the same firmware.

Subject: [PATCH 2041/6423] [media] xc5000: drivers should specify chip
 revision rather than firmware

Specify chip revision at attach time rather than a firmware image.
This is a better way to ensure that the correct firmware is loaded
for the correct revision of the chip.

Subject: [PATCH 2044/6423] xHCI: Kick khubd when USB3 resume really completes.

xHCI roothubs go through slightly different port state machines when
either a device initiates a remote wakeup and signals resume, or when
the host initiates a resume.

According to section 4.19.1.2.13 of the xHCI 1.0 spec, on host-initiated
resume, the xHC port state machine automatically goes through the U3Exit
state into the U0 state, setting the port link state change (PLC) bit in
the process.

When a device initiates resume, the xHCI port state machine goes into
the "Resume" state and sets the PLC bit.  Then the xHCI driver writes U0
into the port link state register to transition the port to U0 from the
Resume state.

We can't be sure the device is actually in the U0 state until we receive
the next port status change event with the PLC bit set.  We really don't
want khubd to be polling the roothub port status bits until the device
is really in U0.

Subject: [PATCH 2045/6423] USB/xhci: Enable remote wakeup for USB3 devices.

When the USB 3.0 hub support went in, I disabled selective suspend for
all external USB 3.0 hubs because they used a different mechanism to
enable remote wakeup.  In fact, other USB 3.0 devices that could signal
remote wakeup would have been prevented from going into suspend because
they would have stalled the SetFeature Device Remote Wakeup request.

This patch adds support for the USB 3.0 way of enabling remote wake up
(with a SetFeature Function Suspend request), and enables selective
suspend for all hubs during hub_probe.  It assumes that all USB 3.0 have
only one "function" as defined by the interface association descriptor,
which is true of all the USB 3.0 devices I've seen so far.  FIXME if
that turns out to change later.

After a device signals a remote wakeup, it is supposed to send a Device
Notification packet to the host controller, signaling which function
sent the remote wakeup.  The host can then put any other functions back
into function suspend.  Since we don't have support for function suspend
(and no devices currently support it), we'll just assume the hub
function will resume the device properly when it received the port
status change notification, and simply ignore any device notification
events from the xHCI host controller.

Subject: [PATCH 2046/6423] USB: Suspend functions before putting dev into U3.

The USB 3.0 bus specification introduces a new type of power management
called function suspend.  The idea is to be able to suspend different
functions (i.e. a scanner or an SD card reader on a USB printer)
independently.  A device can be in U0, but have one or more functions
suspended.  Thus, signaling a function resume with the standard device
remote wake signaling was not possible.

Instead, a device will (without prompt from the host) send a "device
notification" for the function remote wake.  A new Set Feature Function
Remote Wake was developed to turn remote wake up on and off for each
function.

USB 3.0 devices can still go into device suspend (U3), and signal a
remote wakeup to bring the link back into U1.  However, they now use the
function remote wake device notification to allow the host to know which
function woke the device from U3.

The spec is a bit ambiguous about whether a function is allowed to
signal a remote wakeup if the function has been enabled for remote
wakeup, but not placed in function suspend before the device is placed
into U3.

Section 9.2.5.1 says "Suspending a device with more than one function
effectively suspends all the functions within the device."  I interpret
that to mean that putting a device in U3 suspends all functions, and
thus if the host has previously enabled remote wake for those functions,
it should be able to signal a remote wake up on port status changes.
However, hub vendors may have a different interpretation, and it can't
hurt to put the function into suspend before putting the device into U3.

I cannot get an answer out of the USB 3.0 spec architects about this
ambiguity, so I'm erring on the safe side and always suspending the
first function before placing the device in U3.  Note, this code should
be fixed if we ever find any USB 3.0 devices that have more than one
function.

Subject: [PATCH 2047/6423] USB/xHCI: Enable USB 3.0 hub remote wakeup.

USB 3.0 hubs have a different remote wakeup policy than USB 2.0 hubs.
USB 2.0 hubs, once they have remote wakeup enabled, will always send
remote wakes when anything changes on a port.

However, USB 3.0 hubs have a per-port remote wake up policy that is off
by default.  The Set Feature remote wake mask can be changed for any
port, enabling remote wakeup for a connect, disconnect, or overcurrent
event, much like EHCI and xHCI host controller "wake on" port status
bits.  The bits are cleared to zero on the initial hub power on, or
after the hub has been reset.

Without this patch, when a USB 3.0 hub gets suspended, it will not send
a remote wakeup on device connect or disconnect.  This would show up to
the user as "dead ports" unless they ran lsusb -v (since newer versions
of lsusb use the sysfs files, rather than sending control transfers).

Change the hub driver's suspend method to enable remote wake up for
disconnect, connect, and overcurrent for all ports on the hub.  Modify
the xHCI driver's roothub code to handle that request, and set the "wake
on" bits in the port status registers accordingly.

Subject: [PATCH 2048/6423] USB: Refactor hub remote wake handling.

Refactor the code to check for a remote wakeup on a port into its own
function.  Keep the behavior the same, and set connect_change in
hub_events if the device disconnected on resume.  Cleanup references to
hdev->children[i-1] to use a common variable.

Subject: [PATCH 2049/6423] USB/xHCI: Support device-initiated USB 3.0 resume.

USB 3.0 hubs don't have a port suspend change bit (that bit is now
reserved).  Instead, when a host-initiated resume finishes, the hub sets
the port link state change bit.

When a USB 3.0 device initiates remote wakeup, the parent hubs with
their upstream links in U3 will pass the LFPS up the chain.  The first
hub that has an upstream link in U0 (which may be the roothub) will
reflect that LFPS back down the path to the device.

However, the parent hubs in the resumed path will not set their link
state change bit.  Instead, the device that initiated the resume has to
send an asynchronous "Function Wake" Device Notification up to the host
controller.  Therefore, we need a way to notify the USB core of a device
resume without going through the normal hub URB completion method.

First, make the xHCI roothub act like an external USB 3.0 hub and not
pass up the port link state change bit when a device-initiated resume
finishes.  Introduce a new xHCI bit field, port_remote_wakeup, so that
we can tell the difference between a port coming out of the U3Exit state
(host-initiated resume) and the RExit state (ending state of
device-initiated resume).

Since the USB core can't tell whether a port on a hub has resumed by
looking at the Hub Status buffer, we need to introduce a bitfield,
wakeup_bits, that indicates which ports have resumed.  When the xHCI
driver notices a port finishing a device-initiated resume, we call into
a new USB core function, usb_wakeup_notification(), that will set
the right bit in wakeup_bits, and kick khubd for that hub.

We also call usb_wakeup_notification() when the Function Wake Device
Notification is received by the xHCI driver.  This covers the case where
the link between the roothub and the first-tier hub is in U0, and the
hub reflects the resume signaling back to the device without giving any
indication it has done so until the device sends the Function Wake
notification.

Change the code in khubd that handles the remote wakeup to look at the
state the USB core thinks the device is in, and handle the remote wakeup
if the port's wakeup bit is set.

This patch only takes care of the case where the device is attached
directly to the roothub, or the USB 3.0 hub that is attached to the root
hub is the device sending the Function Wake Device Notification (e.g.
because a new USB device was attached).  The other cases will be covered
in a second patch.

Subject: [PATCH 2050/6423] USB: Set wakeup bits for all children hubs.

This patch takes care of the race condition between the Function Wake
Device Notification and the auto-suspend timeout for this situation:

Roothub
  | (U3)
hub A
  | (U3)
hub B
  | (U3)
device C

When device C signals a resume, the xHCI driver will set the wakeup_bits
for the roothub port that hub A is attached to.  However, since USB 3.0
hubs do not set a link state change bit on device-initiated resume, hub
A will not indicate a port event when polled.  Without this patch, khubd
will notice the wakeup-bits are set for the roothub port, it will resume
hub A, and then it will poll the events bits for hub A and notice that
nothing has changed.  Then it will be suspended after 2 seconds.

Change hub_activate() to look at the port link state for each USB 3.0
hub port, and set hub->change_bits if the link state is U0, indicating
the device has finished resume.  Change the resume function called by
hub_events(), hub_handle_remote_wakeup(), to check the link status
for resume instead of just the port's wakeup_bits.

Subject: [PATCH 2051/6423] USB: Turn on auto-suspend for USB 3.0 hubs.

Now that USB 3.0 hub remote wakeup on port status changes is enabled,
and USB 3.0 device remote wakeup is handled in the USB core properly,
let's turn on auto-suspend for all USB 3.0 hubs.

+irq_domain interrupt number mapping library
+
+The current design of the Linux kernel uses a single large number
+space where each separate IRQ source is assigned a different number.
+This is simple when there is only one interrupt controller, but in
+systems with multiple interrupt controllers the kernel must ensure
+that each one gets assigned non-overlapping allocations of Linux
+IRQ numbers.
+
+The irq_alloc_desc*() and irq_free_desc*() APIs provide allocation of
+irq numbers, but they don't provide any support for reverse mapping of
+the controller-local IRQ (hwirq) number into the Linux IRQ number
+space.
+
+The irq_domain library adds mapping between hwirq and IRQ numbers on
+top of the irq_alloc_desc*() API.  An irq_domain to manage mapping is
+preferred over interrupt controller drivers open coding their own
+reverse mapping scheme.
+
+irq_domain also implements translation from Device Tree interrupt
+specifiers to hwirq numbers, and can be easily extended to support
+other IRQ topology data sources.
+
+=== irq_domain usage ===
+An interrupt controller driver creates and registers an irq_domain by
+calling one of the irq_domain_add_*() functions (each mapping method
+has a different allocator function, more on that later).  The function
+will return a pointer to the irq_domain on success.  The caller must
+provide the allocator function with an irq_domain_ops structure with
+the .map callback populated as a minimum.
+
+In most cases, the irq_domain will begin empty without any mappings
+between hwirq and IRQ numbers.  Mappings are added to the irq_domain
+by calling irq_create_mapping() which accepts the irq_domain and a
+hwirq number as arguments.  If a mapping for the hwirq doesn't already
+exist then it will allocate a new Linux irq_desc, associate it with
+the hwirq, and call the .map() callback so the driver can perform any
+required hardware setup.
+
+When an interrupt is received, irq_find_mapping() function should
+be used to find the Linux IRQ number from the hwirq number.
+
+If the driver has the Linux IRQ number or the irq_data pointer, and
+needs to know the associated hwirq number (such as in the irq_chip
+callbacks) then it can be directly obtained from irq_data->hwirq.
+
+=== Types of irq_domain mappings ===
+There are several mechanisms available for reverse mapping from hwirq
+to Linux irq, and each mechanism uses a different allocation function.
+Which reverse map type should be used depends on the use case.  Each
+of the reverse map types are described below:
+
+==== Linear ====
+irq_domain_add_linear()
+
+The linear reverse map maintains a fixed size table indexed by the
+hwirq number.  When a hwirq is mapped, an irq_desc is allocated for
+the hwirq, and the IRQ number is stored in the table.
+
+The Linear map is a good choice when the maximum number of hwirqs is
+fixed and a relatively small number (~ < 256).  The advantages of this
+map are fixed time lookup for IRQ numbers, and irq_descs are only
+allocated for in-use IRQs.  The disadvantage is that the table must be
+as large as the largest possible hwirq number.
+
+The majority of drivers should use the linear map.
+
+==== Tree ====
+irq_domain_add_tree()
+
+The irq_domain maintains a radix tree map from hwirq numbers to Linux
+IRQs.  When an hwirq is mapped, an irq_desc is allocated and the
+hwirq is used as the lookup key for the radix tree.
+
+The tree map is a good choice if the hwirq number can be very large
+since it doesn't need to allocate a table as large as the largest
+hwirq number.  The disadvantage is that hwirq to IRQ number lookup is
+dependent on how many entries are in the table.
+
+Very few drivers should need this mapping.  At the moment, powerpc
+iseries is the only user.
+
+==== No Map ===-
+irq_domain_add_nomap()
+
+The No Map mapping is to be used when the hwirq number is
+programmable in the hardware.  In this case it is best to program the
+Linux IRQ number into the hardware itself so that no mapping is
+required.  Calling irq_create_direct_mapping() will allocate a Linux
+IRQ number and call the .map() callback so that driver can program the
+Linux IRQ number into the hardware.
+
+Most drivers cannot use this mapping.
+
+==== Legacy ====
+irq_domain_add_legacy()
+irq_domain_add_legacy_isa()
+
+The Legacy mapping is a special case for drivers that already have a
+range of irq_descs allocated for the hwirqs.  It is used when the
+driver cannot be immediately converted to use the linear mapping.  For
+example, many embedded system board support files use a set of #defines
+for IRQ numbers that are passed to struct device registrations.  In that
+case the Linux IRQ numbers cannot be dynamically assigned and the legacy
+mapping should be used.
+
+The legacy map assumes a contiguous range of IRQ numbers has already
+been allocated for the controller and that the IRQ number can be
+calculated by adding a fixed offset to the hwirq number, and
+visa-versa.  The disadvantage is that it requires the interrupt
+controller to manage IRQ allocations and it requires an irq_desc to be
+allocated for every hwirq, even if it is unused.
+
+The legacy map should only be used if fixed IRQ mappings must be
+supported.  For example, ISA controllers would use the legacy map for
+mapping Linux IRQs 0-15 so that existing ISA drivers get the correct IRQ
+numbers.

Subject: [PATCH 2054/6423] irq_domain: Make irq_domain structure match
 powerpc's irq_host

Part of the series to unify the irq remapping mechanisms in the
kernel.  A follow up patch will copy the powerpc implementation into
kernel/irq/irqdomain.c, which will be a lot easier if the structures
are identical.

Where they differ, I've chose to use the powerpc names since there is
a lot more code using those names.

From bae1d8f19983fbfa25559aa3cb6a81a84aa82a18 Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Tue, 14 Feb 2012 14:06:50 -0700
Subject: [PATCH 2056/6423] irq_domain/powerpc: Use common irq_domain structure
 instead of irq_host

This patch drops the powerpc-specific irq_host structures and uses the common
irq_domain strucutres defined in linux/irqdomain.h.  It also fixes all
the users to use the new structure names.

Renaming irq_host to irq_domain has been discussed for a long time, and this
patch is a step in the process of generalizing the powerpc virq code to be
usable by all architecture.

An astute reader will notice that this patch actually removes the irq_host
structure instead of renaming it.  This is because the irq_domain structure
already exists in include/linux/irqdomain.h and has the needed data members.

From 4bbdd45afdae208a7c4ade89cf602f89a6397cff Mon Sep 17 00:00:00 2001

Subject: [PATCH 2057/6423] irq_domain/powerpc: eliminate irq_map; use
 irq_alloc_desc() instead

This patch drops the powerpc-specific irq_map table and replaces it with
directly using the irq_alloc_desc()/irq_free_desc() interfaces for allocating
and freeing irq_desc structures.

This patch is a preparation step for generalizing the powerpc-specific virq
infrastructure to become irq_domains.

As part of this change, the irq_big_lock is changed to a mutex from a raw
spinlock.  There is no longer any need to use a spin lock since the irq_desc
allocation code is now responsible for the critical section of finding
an unused range of irq numbers.

The radix lookup table is also changed to store the irq_data pointer instead
of the irq_map entry since the irq_map is removed.  This should end up being
functionally equivalent since only allocated irq_descs are ever added to the
radix tree.

v5: - Really don't ever allocate virq 0.  The previous version could still
      do it if hint == 0
    - Respect irq_virq_count setting for NOMAP.  Some NOMAP domains cannot
      use virq values above irq_virq_count.
    - Use numa_node_id() when allocating irq_descs.  Ideally the API should
      obtain that value from the caller, but that touches a lot of call sites
      so will be deferred to a follow-on patch.
    - Fix irq_find_mapping() to include irq numbers lower than
      NUM_ISA_INTERRUPTS.  With the switch to irq_alloc_desc*(), the lowest
      possible allocated irq is now returned by arch_probe_nr_irqs().
v4: - Fix incorrect access to irq_data structure in debugfs code
    - Don't ever allocate virq 0

Subject: [PATCH 2058/6423] regmap: add regmap_bulk_write() for register write

The bulk_write() supports the data transfer to multi
register which takes the data into cpu_endianness format
and does formatting of data to device format before
sending to device.
The transfer can be completed in single transfer or multiple
transfer based on data formatting.

Subject: [PATCH 2059/6423] staging: tidspbridge: fix bridge_open memory leaks

There are two members of pr_ctxt allocated during bridge_open that
are never freed resulting in memory leaks, these are stream_id and
node_id, they are now freed on release of the handle (bridge_release)
right before freeing pr_ctxt.

Error path for bridge_open was also fixed since the same variables
could result in memory leaking due to missing handling of failure
scenarios. While at it, the indentation changes were introduced to
avoid interleaved goto statements inside big if blocks.

Subject: [PATCH 2061/6423] ASoC: wm9081: Use idle_bias_off

The main role of the WM9081 is as a class D speaker amplifier so there
is no concern about pops. There are also very few registers and a fast
power up time so we can happily mark the driver as idle_bias_off.

Subject: [PATCH 2063/6423] Resurrect Intel740 driver: i740fb

This is a resurrection of an old (like 2.4.19) out-of-tree driver for
Intel740 graphics cards and adaptation for recent kernels. The old driver by
Andrey Ulanov is located at: http://sourceforge.net/projects/i740fbdev/files/

This is a new driver based on skeletonfb, using most of the low level HW code
from the old driver. The DDC code is completely new.

The driver was tested on two 8MB cards: Protac AG240D and Diamond Stealth II
G460.

Subject: [PATCH 2064/6423] NFSv4.1: Convert slotid from u8 to u32

It is perfectly legal to negotiate up to 2^32-1 slots in the protocol,
and with 10GigE, we are already seeing that 255 slots is far too limiting.

Subject: [PATCH 2068/6423] SUNRPC: service destruction in network namespace
 context

v2: Added comment to BUG_ON's in svc_destroy() to make code looks clearer.

This patch introduces network namespace filter for service destruction
function.
Nothing special here - just do exactly the same operations, but only for
tranports in passed networks namespace context.
BTW, BUG_ON() checks for empty service transports lists were returned into
svc_destroy() function. This is because of swithing generic svc_close_all() to
networks namespace dependable svc_close_net().

Subject: [PATCH 2069/6423] SUNRPC: service shutdown function in network
 namespace context introduced

This function is enough for releasing resources, allocated for network
namespace context, in case of sharing service between them.
IOW, each service "user" (LockD, NFSd, etc), which wants to share service
between network namespaces, have to release related resources by the function,
introduced in this patch, instead of performing service shutdown (of course in
case the service is shared already to the moment of release).

Subject: [PATCH 2070/6423] Lockd: create permanent lockd sockets in current
 network namespace

This patch parametrizes Lockd permanent sockets creation routine by network
namespace context.
It also replaces hard-coded init_net with current network namespace context in
Lockd sockets creation routines.
This approach looks safe, because Lockd is created during NFS mount (or NFS
server start) and thus socket is required exactly in current network namespace
context. But in the same time it means, that Lockd sockets inherits first Lockd
requester network namespace. This issue will be fixed in further patches of the
series.

Subject: [PATCH 2071/6423] Lockd: pernet usage counter introduced

Lockd is going to be shared between network namespaces - i.e. going to be able
to handle lock requests from different network namespaces. This means, that
network namespace related resources have to be allocated not once (like now),
but for every network namespace context, from which service is requested to
operate.
This patch implements Lockd per-net users accounting. New per-net counter is
used to determine, when per-net resources have to be freed.

Subject: [PATCH 2072/6423] Lockd: per-net up and down routines introduced

This patch introduces per-net Lockd initialization and destruction routines.
The logic is the same as in global Lockd up and down routines. Probably the
solution is not the best one. But at least it looks clear.
So per-net "up" routine are called only in case of lockd is running already. If
per-net resources are not allocated yet, then service is being registered with
local portmapper and lockd sockets created.
Per-net "down" routine is called on every lockd_down() call in case of global
users counter is not zero.

The wl1251 driver was generating the following warning:

Fix this by removing one cpu_to_le32() call in the wrong place.

But to add support for reading the MAC address from the FUSE in
testmode, we will have to change the partition in testmode.c.

Thus, we move the partition table to io.c and export it via io.h.  It
makes more sense to have it in the io part anyway.

Subject: [PATCH 2094/6423] wl12xx: read chip ID and HW PG version during probe

In order to read the MAC addresses from the fuse ROM, we need to know
the chip ID and the HW PG version.  We need to know the MAC address
during probe, because that's when we register our HW with mac80211.

To prepare for that, this patch reads the chip ID and HW PG version
during probe instead of doing it at boot time.  We power the chip on
briefly in order to do that.

Subject: [PATCH 2095/6423] wl12xx: use two MAC addresses based on the NVS or
 from fuse ROM

Add support for two MAC addresses.  If the NVS has a valid MAC
address, that takes precedence and we use two sequential address
starting from the one specified.

If the NVS doesn't contain a valid MAC address (ie. if it is set to
00:00:00:00:00:00), we check if the HW PG version in use has the
BD_ADDR written in the fuse ROM.  If it does, we read it and derive
the two subsequent addresses for WLAN.

During production, 3 addresses are reserved per device.  The first for
Bluetooth (burnt in the fuse ROM) and the following two for WLAN.

This patch has some code by Igal and Arik (squashed from internal
patches).

Subject: [PATCH 2096/6423] wl12xx: add testmode operation to read the BD_ADDR
 from Fuse ROM

Add a testmode command to retrieve the BD_ADDR that is stored in the
Fuse ROM in newer PGs.  In old PGs this operation is not supported.
The caller can then derive the MAC addresses from it.

Subject: [PATCH 2100/6423] wl12xx: remove wl1271_tx_update_filters

wl1271_tx_update_filters() is used as some workaround
to open filters while roaming on the same channel.

However, it doesn't handle roaming to a different channel,
and it might also sleep in the tx path, which is a bug.

With the new auth/assoc redesign, roaming is much simpler,
and this function is not needed anymore.

This reverts commit 393fb560d328cc06e6a5c7b7473901ad724f82e7.

Commit b6ad726 ("mmc: core: Prevent too long response times
for suspend") fails the suspend if the mmc host can't be
claimed before suspend. As the host is claimed by us as long
as the chip is powered on, suspend will always fail.

Revert to claiming the sdio bus only when needed.

we no longer need to release/claim the host on suspend/resume.

Subject: [PATCH 2103/6423] wl12xx: fw api change - add role_id to set_template

The set_template commands now takes the role_id as
parameter.

Usually, we'll use the vif's main role_id.
However, sometimes we'll want to use
wlvif->dev_role_id instead of wlvif->role_id,
so pass the wanted role_id as param.

Update WL127X_FW_NAME/WL128X_FW_NAME.

(This commit starts a series of fw update patches,
and changes the start() callback to return an error
in order to prevent the use of the driver during the
transition. This change will be reverted in the
last patch of series)

Subject: [PATCH 2104/6423] wl12xx: use dev_role_id for scans

Use device role for scans when the sta is not
associated.

sched_scan is used only when the sta is
not associated, and thus should use
the dev role (instead of sta role).

Subject: [PATCH 2105/6423] wl12xx: fw api change - add role_id to tsf_info

The ACX_TSF_INFO command now takes role_id as param.
change the struct accordingly, and pass the wlvif
to the wl1271_acx_tsf_info() function.

From f1d63a59635feef3481ed1972a883a5d6be7f9bb Mon Sep 17 00:00:00 2001

Date: Tue, 31 Jan 2012 11:57:21 +0200
Subject: [PATCH 2108/6423] wl12xx: add support for HW dynamic PS

FW now supports dynamic PS so we don't need to use mac80211 support.
FW will go to PSM after a specified timeout with no Rx/Tx traffic.
- Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter
- The default PS mode would be dynamic PS
- Default timeout is 100ms (same as it used to be in mac80211)
- Avoid using mac80211 APIs to disable/enable dynamic PS as we're not
using mac80211 PS control anymore.
- COEX is handled by the FW while in dynamic PS so removed
handling of SOFT_GEMINI

Subject: [PATCH 2109/6423] wl12xx: add dynamic_ps_timeout debugfs file

Enable read/write of dynamic_ps_timeout which controls the timeout
of the dynamic PS implemented in the FW.
dynamic_ps_timeout is the timeout (in msec) until going back to PS
when there's no Rx/Tx

Subject: [PATCH 2111/6423] wl12xx: enable/disable BET with AUTO_PS/ACTIVE

While the FW with dynamic PS controls BET when going to PSM and back
internally within the FW, there's still a need to enable it from the driver
at least once (so enable on every entry to AUTO_PS)
and disable it once we explicitly go back to STATION_ACTIVE_MODE.
BET isn't relevant for 5GHz

Subject: [PATCH 2112/6423] wl12xx: change WLVIF_FLAG_PSM name and remove
 WLVIF_FLAG_PSM_REQUESTED

WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which
marks that this vif is in AUTO PS.

WLVIF_FLAG_PSM_REQUESTED is not required as mac80211
calls op_config with CONF_PS after association.

wl12xx_config_vif() handling of CONF_PS was simplified
and cleaned up.

In WEP shared authentication, we encrypt the auth frame

Use the TX_HW_ATTR_HOST_ENCRYPT flag in order to indicate
it to the fw.

Subject: [PATCH 2118/6423] wl12xx: add suspend_listen_interval debugfs file

Add read/write to suspend_dtim_interval file which
controls the number of DTIM periods between wakeups
while the host is suspended.
The value while the host is resumed is controlled
by the file dtim_interval which existed previously.

Subject: [PATCH 2119/6423] wl12xx: add forced_ps mode

For certain WiFi certification tests forcing PS
is necessary. Since DPS is now enabled in the FW
and this can't be achieved by using netlatency
this required a new config option.

Subject: [PATCH 2121/6423] wl12xx: consider encryption and QoS in auto arp
 template

When configuring the arp response template,
and encryption is enabled, we should add some
space and set the protected flag bit in the fc.

In order to track the encryption type, set
wlvif->encryption_type when setting an encryption key,
and reconfigure the arp response. Clear this field on
wl1271_join, as keys have to be re-configured
anyway after a join command.

Similarly, track whether QoS is configured.

Subject: [PATCH 2122/6423] wl12xx: Revert "wl12xx: disable auto-arp"

This reverts commit e5e2f24b3eec67a7a35d43654a997f98ca21aff2.

The encryption consideration on auto-arp configuration,
along with a fw fix, seem to resolve the crashes that
occured when auto-arp was enabled, so we can re-enable it now.

We have to configure arp filtering only after the role was

the join.

Subject: [PATCH 2124/6423] wl12xx: declare support for hw scan while idle

By allowing hw scan while idle, we no longer
need the redundant ROC/CROC that are done
on idle off/on, which helps simplifying the
state machine of the driver.

This way, we can also allow scanning while
there is an ongoing sched scan (otherwise,
we won't be able to ROC on idle-off)

Subject: [PATCH 2125/6423] wl12xx: don't fail on AP scan

AP role uses its own role_id for scans, so there's
no reason to fail the scan if dev_role_id is invalid.

Subject: [PATCH 2127/6423] wl12xx: use split scan for normal scan

Split scan allows the FW to schedule other activities
during a scan which may be a long operation. This is
achieved by setting a trigger TID to ANY_TID and a scan
trigger timeout other than 0. The default one is set to 50ms.

Subject: [PATCH 2129/6423] wl12xx: Use a dedicated fw for PLT

A special PLT firmware is used for calibration.

Add multiple fw support by introducing a new fw_type member,
representing the currently saved fw (the actual fw state
can be determined by wl->state).

Subject: [PATCH 2130/6423] wl12xx: dynamically change fw according to number
 of active roles

wl12xx uses different fw for single-role and multi-role
scenarios (due to lack of space, some of the fw advanced
features are disabled in the multi-role fw).

Add checks on add_interfae and remove_interface in order
to determine whether a fw switch is needed (and initiate
recovery in this case).

Subject: [PATCH 2136/6423] usb: gadget: Add Audio Class 2.0 Driver

This is a flexible USB Audio Class 2.0 compliant gadget driver that
implements a simple topology with a virtual sound card exposed at
the function side.

The driver doesn't expect any real audio codec to be present on the
function - the audio streams are simply sinked to and sourced from a
virtual ALSA sound card created. The user-space application may choose
to do whatever it wants with the data received from the USB Host and
choose to provide whatever it wants as audio data to the USB Host.

Capture(USB-Out) and Playback(USB-In) can be run at independent
configurations specified via module parameters while loading the driver.

Make this new version as the default selection by a new Kconfig choice.

"ret" has already been checked at this point, and we don't need to check
it again.  This was left around from a previous patch 49d750ca14
"wl12xx: 1281/1283 support - New radio structs and functions".

In case of Start Discovery command failure, we should set the discovery
state to DISCOVERY_STOPPED. Otherwise, we stuck at DISCOVERY_STARTING
state and subsequent Start Discovery commands will simply fail.

Subject: [PATCH 2141/6423] drm/i915: Record the tail at each request and use
 it to estimate the head

By recording the location of every request in the ringbuffer, we know
that in order to retire the request the GPU must have finished reading
it and so the GPU head is now beyond the tail of the request. We can
therefore provide a conservative estimate of where the GPU is reading
from in order to avoid having to read back the ring buffer registers
when polling for space upon starting a new write into the ringbuffer.

A secondary effect is that this allows us to convert
intel_ring_buffer_wait() to use i915_wait_request() and so consolidate
upon the single function to handle the complicated task of waiting upon
the GPU. A necessary precaution is that we need to make that wait
uninterruptible to match the existing conditions as all the callers of
intel_ring_begin() have not been audited to handle ERESTARTSYS
correctly.

By using a conservative estimate for the head, and always processing all
outstanding requests first, we prevent a race condition between using
the estimate and direct reads of I915_RING_HEAD which could result in
the value of the head going backwards, and the tail overflowing once
again. We are also careful to mark any request that we skip over in
order to free space in ring as consumed which provides a
self-consistency check.

Given sufficient abuse, such as a set of unthrottled GPU bound
cairo-traces, avoiding the use of I915_RING_HEAD gives a 10-20% boost on
Sandy Bridge (i5-2520m):
  firefox-paintball  18927ms -> 15646ms: 1.21x speedup
  firefox-fishtank   12563ms -> 11278ms: 1.11x speedup
which is a mild consolation for the performance those traces achieved from
exploiting the buggy autoreported head.

v2: Add a few more comments and make request->tail a conservative
estimate as suggested by Daniel Vetter.

Subject: [PATCH 2142/6423] drm/i915: Record the in-flight requests at the time
 of a hang

Being able to tally the list of outstanding requests with the sequence
of commands in the ringbuffer is often useful evidence with respect to
driver corruption.

Note that since this is the umpteenth per-ring data structure to be added
to the error state, I've coallesced the nearby loops (the ringbuffer and
batchbuffer) into a single structure along with the list of requests.  A
later task would be to refactor the ring register state into the same
structure.

v2: Fix pretty printing of requests so that they are parsed correctly by
intel_error_decode and use the 0x%08x format for seqno for consistency

Subject: [PATCH 2146/6423] [media] hdpvr: update picture controls to support
 firmware versions > 0.15

Correctly sets the max/min/default values for the hdpvr picture
controls. The reason the current values didn't cause a problem until now
is because any firmware <= 0.15 didn't support them. The latest firmware
releases properly support picture controls and the values in the patch
are derived from the windows driver using SniffUSB2.0.

Thanks to Devin Heitmueller for helping me.

Subject: [PATCH 2147/6423] drm/i915/lvds: Always use the presence pin for LVDS
 on PCH

With the introduction of the PCH, we gained an LVDS presence pin but we
continued to use the existing logic that asserted that LVDS was only
supported on certain mobile chipsets. However, there are desktop
IronLake systems with LVDS attached which we fail to detect. So for PCH,
trust the LVDS presence pin and quirk all the lying manufacturers.

Subject: [PATCH 2148/6423] ASoC: dapm - Make DAPM reset code a separate
 function.

It's useful to export the DAPM reset as a static function for future use
by other DAPM functions. e.g. The dynamic PCM query widgets resets the DAPM
graph before working out active paths.

Currently when DAPM widgets are power sequenced the stream_event()
completion callback is only called for the stream_event originator
DAPM context. Other components in the card may also be interested so
make sure they are also notified of any widget power events.

Since the addition of the non-CODEC control adds card controls like the
DAPM pin switch have been broken as they are expecting the private data
for the control to be the CODEC but it's now the card. Fix that for the
pin switches, an audit of other drivers is required.

Subject: [PATCH 2155/6423] staging: ramster: cluster/messaging foundation

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

This patch provides the cluster and messaging foundation for RAMster,
implementing the basic cluster discovery, mapping, heartbeat / keepalive,
and messaging ("r2net") that RAMster requires for internode communication.
This code heavily leverages code from the ocfs2 cluster layer but
has been extended, interfaces to userland changed, and external functions
renamed so that RAMster and ocfs2 can co-exist in the kernel and userland.

+/*
+ * For now this is a trivial wrapper around printk() that gives the critical
+ * ability to enable sets of debugging output at run-time.  In the future this
+ * will almost certainly be redirected to relayfs so that it can pay a
+ * substantially lower heisenberg tax.
+ *
+ * Callers associate the message with a bitmask and a global bitmask is
+ * maintained with help from /proc.  If any of the bits match the message is
+ * output.
+ *
+ * We must have efficient bit tests on i386 and it seems gcc still emits crazy
+ * code for the 64bit compare.  It emits very good code for the dual unsigned
+ * long tests, though, completely avoiding tests that can never pass if the
+ * caller gives a constant bitmask that fills one of the longs with all 0s.  So
+ * the desire is to have almost all of the calls decided on by comparing just
+ * one of the longs.  This leads to having infrequently given bits that are
+ * frequently matched in the high bits.
+ *
+ * _ERROR and _NOTICE are used for messages that always go to the console and
+ * have appropriate KERN_ prefixes.  We wrap these in our function instead of
+ * just calling printk() so that this can eventually make its way through
+ * relayfs along with the debugging messages.  Everything else gets KERN_DEBUG.
+ * The inline tests and macro dance give GCC the opportunity to quite cleverly
+ * only emit the appropriage printk() when the caller passes in a constant
+ * mask, as is almost always the case.
+ *
+ * All this bitmask nonsense is managed from the files under
+ * /sys/fs/r2cb/logmask/.  Reading the files gives a straightforward
+ * indication of which bits are allowed (allow) or denied (off/deny).
+ *	ENTRY deny
+ *	EXIT deny
+ *	TCP off
+ *	MSG off
+ *	SOCKET off
+ *	ERROR allow
+ *	NOTICE allow
+ *
+ * Writing changes the state of a given bit and requires a strictly formatted
+ * single write() call:
+ *
+ *	write(fd, "allow", 5);
+ *
+ * Echoing allow/deny/off string into the logmask files can flip the bits
+ * on or off as expected; here is the bash script for example:
+ *
+ * log_mask="/sys/fs/r2cb/log_mask"
+ * for node in ENTRY EXIT TCP MSG SOCKET ERROR NOTICE; do
+ *	echo allow >"$log_mask"/"$node"
+ * done
+ *
+ * The debugfs.ramster tool can also flip the bits with the -l option:
+ *
+ * debugfs.ramster -l TCP allow

+ * ----
+ *
+ * Callers for this were originally written against a very simple synchronus
+ * API.  This implementation reflects those simple callers.  Some day I'm sure
+ * we'll need to move to a more robust posting/callback mechanism.
+ *
+ * Transmit calls pass in kernel virtual addresses and block copying this into
+ * the socket's tx buffers via a usual blocking sendmsg.  They'll block waiting
+ * for a failed socket to timeout.  TX callers can also pass in a poniter to an
+ * 'int' which gets filled with an errno off the wire in response to the
+ * message they send.
+ *
+ * Handlers for unsolicited messages are registered.  Each socket has a page
+ * that incoming data is copied into.  First the header, then the data.
+ * Handlers are called from only one thread with a reference to this per-socket
+ * page.  This page is destroyed after the handler call, so it can't be
+ * referenced beyond the call.  Handlers may block but are discouraged from
+ * doing so.
+ *
+ * Any framing errors (bad magic, large payload lengths) close a connection.
+ *
+ * Our sock_container holds the state we associate with a socket.  It's current
+ * framing state is held there as well as the refcounting we do around when it
+ * is safe to tear down the socket.  The socket is only finally torn down from
+ * the container when the container loses all of its references -- so as long
+ * as you hold a ref on the container you can trust that the socket is valid
+ * for use with kernel socket APIs.
+ *
+ * Connections are initiated between a pair of nodes when the node with the
+ * higher node number gets a heartbeat callback which indicates that the lower
+ * numbered node has started heartbeating.  The lower numbered node is passive
+ * and only accepts the connection if the higher numbered node is heartbeating.

From 19ee3ef5f4bb22d17eb73d89a520437745b8b444 Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Wed, 15 Feb 2012 07:54:16 -0800
Subject: [PATCH 2156/6423] staging: ramster: local compression + tmem

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

This patch copies files from drivers/staging/zcache.  RAMster compresses
pages locally before transmitting them to another node, so we can
leverage the zcache and tmem code directly.  Note: there are
no ramster-specific changes yet to these files.

(Why copy?  The ramster tmem.c/tmem.h changes are definitely shareable
between zcache and ramster; the eventual destination for tmem.c
is the linux lib directory.  Ramster changes to zcache are more substantial
and zcache is currently undergoing some significant unrelated changes
(including a new allocator and breaking zcache-main.c into smaller files),
so it seemed best to branch temporarily and merge later.)

+ * In-kernel transcendent memory (generic implementation)
+ *
+ * Copyright (c) 2009-2011, Dan Magenheimer, Oracle Corp.
+ *
+ * The primary purpose of Transcedent Memory ("tmem") is to map object-oriented
+ * "handles" (triples containing a pool id, and object id, and an index), to
+ * pages in a page-accessible memory (PAM).  Tmem references the PAM pages via
+ * an abstract "pampd" (PAM page-descriptor), which can be operated on by a
+ * set of functions (pamops).  Each pampd contains some representation of
+ * PAGE_SIZE bytes worth of data. Tmem must support potentially millions of
+ * pages and must be able to insert, find, and delete these pages at a
+ * potential frequency of thousands per second concurrently across many CPUs,
+ * (and, if used with KVM, across many vcpus across many guests).
+ * Tmem is tracked with a hierarchy of data structures, organized by
+ * the elements in a handle-tuple: pool_id, object_id, and page index.
+ * One or more "clients" (e.g. guests) each provide one or more tmem_pools.
+ * Each pool, contains a hash table of rb_trees of tmem_objs.  Each
+ * tmem_obj contains a radix-tree-like tree of pointers, with intermediate
+ * nodes called tmem_objnodes.  Each leaf pointer in this tree points to
+ * a pampd, which is accessible only through a small set of callbacks
+ * registered by the PAM implementation (see tmem_register_pamops). Tmem
+ * does all memory allocation via a set of callbacks registered by the tmem
+ * host implementation (e.g. see tmem_register_hostops).

+ * Zcache provides an in-kernel "host implementation" for transcendent memory
+ * and, thus indirectly, for cleancache and frontswap.  Zcache includes two
+ * page-accessible memory [1] interfaces, both utilizing lzo1x compression:
+ * 1) "compression buddies" ("zbud") is used for ephemeral pages
+ * 2) xvmalloc is used for persistent pages.
+ * Xvmalloc (based on the TLSF allocator) has very low fragmentation
+ * so maximizes space efficiency, while zbud allows pairs (and potentially,
+ * in the future, more than a pair of) compressed pages to be closely linked
+ * so that reclaiming can be done via the kernel's physical-page-oriented
+ * "shrinker" interface.
+ *
+ * [1] For a definition of page-accessible memory (aka PAM), see:

From b95e141a6471e744f963b78c069f35db4771eaf3 Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Wed, 15 Feb 2012 07:54:17 -0800
Subject: [PATCH 2157/6423] staging: ramster: xvmalloc allocation files

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

Zcache is in the process of converting allocators, from xvmalloc to zsmalloc.
Further, RAMster V5 testing to date has been done only with xvmalloc.
To avoid merging problems, a linux-3.2 copy of xvmalloc is incorporated by
this patch.  Later patches will be able to eliminate xvmalloc and use zsmalloc.

From c89126eabb1ec17ab3af43ec7975bc49fdc729aa Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Wed, 15 Feb 2012 07:54:18 -0800
Subject: [PATCH 2158/6423] staging: ramster: ramster-specific changes to
 zcache/tmem

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

This patch incorporates changes transforming zcache to work with
a remote store.

In tmem.[ch], new "repatriate" (provoke async get) and "localify" (handle
incoming data resulting from an async get) routines combine with a handful
of changes to existing pamops interfaces allow the generic tmem code
to support asynchronous operations.  Also, a new tmem_xhandle struct
groups together key information that must be passed to remote tmem stores.

Zcache-main.c is augmented with a large amount of ramster-specific code
to handle remote operations and "foreign" pages on both ends of the
"remotify" protocol.  New "foreign" pools are auto-created on demand.
A "selfshrinker" thread periodically repatriates remote persistent pages
when local memory conditions allow.  For certain operations, a queue is
necessary to guarantee strict ordering as out-of-order puts/flushes can
cause strange race conditions.  Pampd pointers now either point to local
memory OR describe a remote page; to allow the same 64-bits to describe
either, the LSB is used to differentiate.  Some acrobatics must be performed
to ensure local memory is available to handle a remote persistent get,
or deal with the data directly anyway if the malloc failed.  Lots
of ramster-specific statistics are available via sysfs.

Note: Some debug ifdefs left in for now.

-	  Zcache doubles RAM efficiency while providing a significant
-	  performance boosts on many workloads.  Zcache uses lzo1x
-	  compression and an in-kernel implementation of transcendent
-	  memory to store clean page cache pages and swap in RAM,
-	  providing a noticeable reduction in disk I/O.
+	  RAMster allows RAM on other machines in a cluster to be utilized
+	  dynamically and symmetrically instead of swapping to a local swap
+	  disk, thus improving performance on memory-constrained workloads
+	  while minimizing total RAM across the cluster.  RAMster, like
+	  zcache, compresses swap pages into local RAM, but then remotifies
+	  the compressed pages to another node in the RAMster cluster.

From 83bc7a7cd2d6b733290d257867500c5674fe69f5 Mon Sep 17 00:00:00 2001
From: Dan Magenheimer <dan.magenheimer@oracle.com>
Date: Wed, 15 Feb 2012 07:54:19 -0800
Subject: [PATCH 2159/6423] staging: ramster: ramster-specific new files

RAMster implements peer-to-peer transcendent memory, allowing a "cluster"
of kernels to dynamically pool their RAM.

This patch adds new files necessary for ramster support:  The file
ramster.h declares externs and some pampd bitfield manipulation.  The
file zcache.h declares some zcache functions that now must be accessed
from the ramster glue code.  The file r2net.c is the glue between zcache
and the messaging layer, providing routines called from zcache that
initiate messages, and routines that handle messages by calling zcache.
TODO explains future plans for merging.

+For this staging driver, RAMster duplicates code from drivers/staging/zcache
+then incorporates changes to the local copy of the code.  For V5, it also
+directly incorporates the soon-to-be-removed drivers/staging/zram/xvmalloc.[ch]
+as all testing has been done with xvmalloc rather than the new zsmalloc.
+Before RAMster can be promoted from staging, the zcache and RAMster drivers
+should be either merged or reorganized to separate out common code.
+
+Until V4, RAMster duplicated code from fs/ocfs2/cluster, but this made
+RAMster incompatible with ocfs2 running in the same kernel and included
+lots of code that could be removed.  As of V5, the ocfs2 code has been
+mined and made RAMster-specific, made to communicate with a userland
+ramster-tools package rather than ocfs2-tools, and can co-exist with ocfs2
+both in the same kernel and in userland on the same machine.

Subject: [PATCH 2161/6423] bnx2x: consistent statistics after internal driver
 reload

Currently bnx2x statistics are reset by inner driver reload, e.g. by MTU
change. This patch fixes this issue - from now on statistics should only
be reset upon device closure.
Thanks to Michal Schmidt <mschmidt@redhat.com> for his initial patch
regarding this issue.

Subject: [PATCH 2166/6423] bnx2x: allocate memory dynamically in ethtool
 self-test.

From: Merav Sicron <meravs@broadcom.com>

Current ethtool self tests usesa large buffer on stack. This patch replaces
that array by dynamically allocated memory

 eth_hw_addr_random()

Replace usage of random_ether_addr() with eth_hw_addr_random()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Change the trivial cases.

v2: adapt to renamed eth_hw_addr_random()

From 7ce5d222190cb3ce3ae88bafde7c4fa52a5103e0 Mon Sep 17 00:00:00 2001
From: Danny Kukawka <danny.kukawka@bisect.de>
Date: Wed, 15 Feb 2012 06:45:40 +0000
Subject: [PATCH 2173/6423] net: use eth_hw_addr_random() and reset
 addr_assign_type

Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: adapt to renamed eth_hw_addr_random()

Subject: [PATCH 2179/6423] ipv4: Eliminate spurious argument to
 __ipv4_neigh_lookup

'tbl' is always arp_tbl, so specifying it is pointless.

Subject: [PATCH 2180/6423] Yama: add PR_SET_PTRACER_ANY

For a process to entirely disable Yama ptrace restrictions, it can use
the special PR_SET_PTRACER_ANY pid to indicate that any otherwise allowed
process may ptrace it. This is stronger than calling PR_SET_PTRACER with
pid "1" because it includes processes in external pid namespaces. This is
currently needed by the Chrome renderer, since its crash handler (Breakpad)
runs external to the renderer's pid namespace.

Subject: [PATCH 2181/6423] sfc: Add support for configuring RX
 unicast/multicast default filters

On Siena all received packets that don't match a more specific filter
will match the unicast or multicast default filter.  Currently we
leave these set to the default values (RSS with base queue number of
0).  Allow them to be reconfigured to select a single RX queue.

These default filters are programmed through the FILTER_CTL register,
but we represent them internally as an additional table of size 2.

Subject: [PATCH 2182/6423] sfc: Add support for TX MAC filters

On Siena each TX queue can be configured to send only packets for
which there is a TX MAC filter that matches the source MAC address,
queue ID, and optionally VID.  This will be used to implement the
'spoofchk' feature for SR-IOV virtual functions.

Subject: [PATCH 2183/6423] sfc: Correct MAC filter bitfield definitions

The RMFT_DEST_MAC and TMFT_SRC_MAC register fields were previously
documented as 44 bits wide, whereas a MAC address has 48 bits.
Thankfully the hardware uses the correct width and the driver has
used separate definitions that divide each of these into 32-bit and
16-bit fields.

Fix the initial definitions for these fields and rewrite the latter
definitions to use them.

From 9f2cb71c2b0ce33c472856c0feec2883fa0d9cd1 Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Wed, 8 Feb 2012 00:11:20 +0000
Subject: [PATCH 2186/6423] sfc: Leave interrupts and event queues enabled
 whenever we can

When SR-IOV is enabled we may receive FLR (Function-Level Reset)
events, associated queue flush events and requests from VF drivers at
any time.  Therefore we need to keep event queues and interrupts
enabled whenever possible.

Currently we stop interrupt-driven event processing before flushing RX
and TX queues; efx_nic_flush_queues() then polls event queues for
flush events and discards any others it finds.  Change it to work with
the regular event handling functions.

Currently efx_start_channel() fills RX queues synchronously when a
device is brought up.  This could now race with NAPI, so change it to
send fill events.

This was almost entirely written by Steve Hodgson, formerly
shodgson@solarflare.com.

Subject: [PATCH 2188/6423] sfc: Generalise event generation to cover VF-owned
 event queues

For SR-IOV we will need to send events to event queues that belong to
VFs serviced by other drivers.  Change the parameters of
efx_generate_event() to allow this and declare it extern.

While we're at it, remove the existing declaration under the wrong
name efx_nic_generate_event().

Subject: [PATCH 2189/6423] sfc: Disable flow control during flushes

The TX DMA engine issues upstream read requests when there is room in
the TX FIFO for the completion. However, the fetches for the rest of
the packet might be delayed by any back pressure.  Since a flush must
wait for an EOP, the entire flush may be delayed by back pressure.

Mitigate this by disabling flow control before the flushes are
started.  Since PF and VF flushes run in parallel introduce
fc_disable, a reference count of the number of flushes outstanding.

The same principle could be applied to Falcon, but that
would bring with it its own testing.

Subject: [PATCH 2192/6423] sfc: Add support for 'extra' channel types

Abstract some of the channel operations to allow for 'extra'
channels that do not have RX or TX queues.

- Try to assign a channel to each extra channel type that is enabled
  for the NIC, but gracefully degrade if we can't allocate sufficient
  MSI-X vectors
- Allow each extra channel type to generate its own channel name
- Allow channel types to disable reallocation and reinitialisation
  of their channels

From a9a52506277275b73955504bf4df745502a28b8b Mon Sep 17 00:00:00 2001
From: Ben Hutchings <bhutchings@solarflare.com>
Date: Tue, 14 Feb 2012 20:15:57 +0000
Subject: [PATCH 2193/6423] sfc: Pass NIC structure into
 efx_wanted_parallelism()

This lets us identify the NIC affected in case of failure, and
will be necessary to adjust for SR-IOV constraints.

Subject: [PATCH 2194/6423] sfc: Allocate SRAM between buffer table and
 descriptor caches at init time

Each port has a block of 64-bit SRAM that is divided between buffer
table and descriptor cache regions at initialisation time.  Currently
we use a fixed allocation, but it needs to be changed to support
larger numbers of queues.

Subject: [PATCH 2195/6423] sfc: Add SR-IOV back-end support for SFC9000 family

On the SFC9000 family, each port has 1024 Virtual Interfaces (VIs),
each with an RX queue, a TX queue, an event queue and a mailbox
register.  These may be assigned to up to 127 SR-IOV virtual functions
per port, with up to 64 VIs per VF.

We allocate an extra channel (IRQ and event queue only) to receive
requests from VF drivers.

There is a per-port limit of 4 concurrent RX queue flushes, and queue
flushes may be initiated by the MC in response to a Function Level
Reset (FLR) of a VF.  Therefore, when SR-IOV is in use, we submit all
flush requests via the MC.

The RSS indirection table is shared with VFs, so the number of RX
queues used in the PF is limited to the number of VIs per VF.

This is almost entirely the work of Steve Hodgson, formerly
shodgson@solarflare.com.

+/**
+ * DOC: Virtual Function Driver Interface
+ *
+ * This file contains software structures used to form a two way
+ * communication channel between the VF driver and the PF driver,
+ * named Virtual Function Driver Interface (VFDI).
+ *
+ * For the purposes of VFDI, a page is a memory region with size and
+ * alignment of 4K.  All addresses are DMA addresses to be used within
+ * the domain of the relevant VF.
+ *
+ * The only hardware-defined channels for a VF driver to communicate
+ * with the PF driver are the event mailboxes (%FR_CZ_USR_EV
+ * registers).  Writing to these registers generates an event with
+ * EV_CODE = EV_CODE_USR_EV, USER_QID set to the index of the mailbox
+ * and USER_EV_REG_VALUE set to the value written.  The PF driver may
+ * direct or disable delivery of these events by setting
+ * %FR_CZ_USR_EV_CFG.
+ *
+ * The PF driver can send arbitrary events to arbitrary event queues.
+ * However, for consistency, VFDI events from the PF are defined to
+ * follow the same form and be sent to the first event queue assigned
+ * to the VF while that queue is enabled by the VF driver.
+ *
+ * The general form of the variable bits of VFDI events is:
+ *
+ *       0             16                       24   31
+ *      | DATA        | TYPE                   | SEQ   |
+ *
+ * SEQ is a sequence number which should be incremented by 1 (modulo
+ * 256) for each event.  The sequence numbers used in each direction
+ * are independent.
+ *
+ * The VF submits requests of type &struct vfdi_req by sending the
+ * address of the request (ADDR) in a series of 4 events:
+ *
+ *       0             16                       24   31
+ *      | ADDR[0:15]  | VFDI_EV_TYPE_REQ_WORD0 | SEQ   |
+ *      | ADDR[16:31] | VFDI_EV_TYPE_REQ_WORD1 | SEQ+1 |
+ *      | ADDR[32:47] | VFDI_EV_TYPE_REQ_WORD2 | SEQ+2 |
+ *      | ADDR[48:63] | VFDI_EV_TYPE_REQ_WORD3 | SEQ+3 |
+ *
+ * The address must be page-aligned.  After receiving such a valid
+ * series of events, the PF driver will attempt to read the request
+ * and write a response to the same address.  In case of an invalid
+ * sequence of events or a DMA error, there will be no response.
+ *
+ * The VF driver may request that the PF driver writes status
+ * information into its domain asynchronously.  After writing the
+ * status, the PF driver will send an event of the form:
+ *
+ *       0             16                       24   31
+ *      | reserved    | VFDI_EV_TYPE_STATUS    | SEQ   |
+ *
+ * In case the VF must be reset for any reason, the PF driver will
+ * send an event of the form:
+ *
+ *       0             16                       24   31
+ *      | reserved    | VFDI_EV_TYPE_RESET     | SEQ   |
+ *
+ * It is then the responsibility of the VF driver to request
+ * reinitialisation of its queues.

Subject: [PATCH 2197/6423] usb: host: ehci: allow ehci_* symbols to be unused

not all platforms will use all of those ehci_*
symbols on their hc_driver structure. Sometimes
we might need to provide a modified version of
a certain method or not provide it at all, as is
the case with OMAPs which don't support port handoff
feature.

Whenever we compile a kernel for an OMAP board with
EHCI enabled, we get compile warnings:

drivers/usb/host/ehci-hub.c:1079: warning: 'ehci_relinquish_port' \
	defined but not used
drivers/usb/host/ehci-hub.c:1088: warning: 'ehci_port_handed_over' \
	defined but not used

In order to cleanup those warnings, we're adding
__maybe_unused annotation to those functions.

Subject: [PATCH 2198/6423] w1: Fix w1_bq27000

w1_bq27000 adds a bq27000-battery platform device but does not provide
platform data for it. This causes the bq27x00 driver to dereference a NULL
pointer.
So provide the appropriate platform data.  This requires modifying
w1_bq27000_read so that it find the w1 device as the parent of the bq device.

Also there is no point exporting w1_bq27000_read as nothing else uses it
or could use it.  So make it static.

Finally, as there is no way to track how many batteries have been found, and
we will probably only find one, use an id number of '-1' to assert that this
is a unique instance.

Subject: [PATCH 2201/6423] Staging, rtl8192e, softmac: remove redundant memset
 and fix mem leak

In drivers/staging/rtl8192e/rtllib_softmac.c::rtllib_rx_assoc_resp()
we allocate memory for 'network' with kzalloc() and then proceed to
zero the already zeroed mem we got from kzalloc() with
memset(). That's redundant, so remove the memset()

We also fail to kfree() the memory we allocated for 'network' if we do not enter

  if (ieee->current_network.qos_data.supported == 1) {

and the variable then goes out of scope.

To fix that I simply moved the kfree() that was inside that 'if'
statement to instead be just after it. It then covers both the case
where we take the branch and when we don't.

Commit b66b8b9a4a79087dde1b358a016e5c8739ccf186 ('intel-idle: convert
to x86_cpu_id auto probing') added a distinction between Nehalem and
Westemere processors and changed auto_demotion_disable_flags for the
former to 0.  This was not explained in the commit message, so change
it back.

the code for other architectures.

This reverts commit e167976ee7f5fe4b80f7e8f55e087f6c67cf9562,
Since this was already fixed in commit
3bd3c9329973a93fa3ef5e9840f2fd6fa2889e3f some days before this
commit cause seq_file.h to be included twice.

Subject: [PATCH 2210/6423] ALSA: hda/realtek - Add the fixup codes for ALC260
 model=will

The model=will for ALC260 requires the pin 0x0f to be a headphone and
some special verbs for the COEF to turn on the amp.  Now added these as
fixup entries and removed the static model quirk.

Subject: [PATCH 2211/6423] ALSA: hda/realtek - Replace ALC260 model=acer with
 the auto-parser

The ALC260 model=acer needs GPIO1 setup.  It could be selected well
if the codec SSID is set properly by BIOS, but to make sure, enable it
forcibly.

Subject: [PATCH 2212/6423] ALSA: hda/realtek - Replace ALC260 model=replacer
 with the auto-parser

The support for Replacer 627V in the auto-parser needs the unique unsol
event handling: although the machine has a single output pin 0x0f, it's
used for both the headphone and the speaker, and the driver needs to
toggle the output route via GPIO 1.

In addition, it needs a special COEF setup with 0x3050.

Subject: [PATCH 2216/6423] ALSA: hda/realtek - Remove leftover static quirks
 for ALC260

Now we can clean up all static quirks for ALC260.
Also many codes in alc_quirks.c can be ripped off since they have been
used only by ALC260 static quirks.

Subject: [PATCH 2217/6423] ALSA: hda/realtek - Disable static fixups for ASUS
 with ALC269

We've enabled the static fixups for ASUS machines with ALC269 codec,
just for making things compatible during the transition to the auto-
parser.  However, it seems that the static configurations do more harmful
than good, as some of entries don't match with the actual hardware setups.

Subject: [PATCH 2220/6423] irq_domain: Replace irq_alloc_host() with
 revmap-specific initializers

Each revmap type has different arguments for setting up the revmap.
This patch splits up the generator functions so that each revmap type
can do its own setup and the user doesn't need to keep track of how
each revmap type handles the arguments.

This patch also adds a host_data argument to the generators.  There are
cases where the host_data pointer will be needed before the function returns.
ie. the legacy map calls the .map callback for each irq before returning.

v2: - Add void *host_data argument to irq_domain_add_*() functions
    - fixed failure to compile

Subject: [PATCH 2221/6423] irq_domain: Add support for base irq and hwirq in
 legacy mappings

Add support for a legacy mapping where irq = (hwirq - first_hwirq + first_irq)
so that a controller driver can allocate a fixed range of irq_descs and use
a simple calculation to translate back and forth between linux and hw irq
numbers.  This is needed to use an irq_domain with many of the ARM interrupt
controller drivers that manage their own irq_desc allocations.  Ultimately
the goal is to migrate those drivers to use the linear revmap, but doing it
this way allows each driver to be converted separately which makes the
migration path easier.

This patch generalizes the IRQ_DOMAIN_MAP_LEGACY method to use
(first_irq-first_hwirq) as the offset between hwirq and linux irq number,
and adds checks to make sure that the hwirq number does not exceed range
assigned to the controller.

Subject: [PATCH 2224/6423] irq_domain: Remove 'new' irq_domain in favour of
 the ppc one

This patch removes the simplistic implementation of irq_domains and enables
the powerpc infrastructure for all irq_domain users.  The powerpc
infrastructure includes support for complex mappings between Linux and
hardware irq numbers, and can manage allocation of irq_descs.

This patch also converts the few users of irq_domain_add()/irq_domain_del()
to call irq_domain_add_legacy() instead.

v3: Fix bug that set up too many irqs in translation range.
v2: Fix removal of irq_alloc_descs() call in gic driver

From 6b783f7c5dde2648fa0bbe7fc8ac80d78699e67f Mon Sep 17 00:00:00 2001

Subject: [PATCH 2225/6423] irq_domain: Remove irq_domain_add_simple()

irq_domain_add_simple() was a stop-gap measure until complete irq_domain
support was complete.  This patch removes the irq_domain_add_simple()
interface.

This patch also drops the explicit irq_domain initialization performed
by the mach-versatile code because the versatile interrupt controller
already has irq_domain support built into it.  This was a bug that was
hanging around quietly for a while, but with the full irq_domain which
actually verifies that irq_domain ranges are available it would cause
the registration to fail and the system wouldn't boot.

v4: Fixed number of irqs in mx5 gpio code
v2: Updated to pass in host_data pointer on irq_domain allocation.

Subject: [PATCH 2226/6423] irq_domain: Create common xlate functions that
 device drivers can use

Rather than having each interrupt controller driver creating its own barely
unique .xlate function for irq_domain, create a library of translators which
any driver can use directly.

v5: - Remove irq_domain_xlate_pci().  It was incorrect.

From 0bd761e1b6d909d3fd08841be7d5035f9fde8a53 Mon Sep 17 00:00:00 2001
From: Mark Salter <msalter@redhat.com>
Date: Thu, 26 Jan 2012 09:26:21 -0500
Subject: [PATCH 2228/6423] irq_domain/c6x: Convert c6x to use generic
 irq_domain support.

The C6X IRQ support was copied almost verbatim from the PowerPC virtual IRQ
code. The PowerPC code was used as the basis for generic irq_domain support,
so this patch mostly copies what what done to arch/powerpc by Grant Likely
in his irq_domain patch series.

From ff8c3ab8161d0df52858966e0347e05791da40df Mon Sep 17 00:00:00 2001
From: Grant Likely <grant.likely@secretlab.ca>
Date: Tue, 24 Jan 2012 17:09:13 -0700
Subject: [PATCH 2232/6423] irq_domain/powerpc: Replace custom xlate functions
 with library functions

This patch converts a number of the powerpc drivers to use the common library
of irq_domain xlate functions, dropping a bunch of lines in the process.

v5: - Remove tsi108 changes from patch

Subject: [PATCH 2233/6423] irq_domain/microblaze: Convert microblaze to use
 irq_domains

This patch converts Microblaze to use the irq_domain remapper and get
away from hard coding the offset between hwirq number and the linux irq
number space.  This also paves the way for multiple interrupt controllers.

v2: Don't enable SPARSE_IRQ and keep NR_IRQS set to 33

Subject: [PATCH 2236/6423] ALSA: hda/realtek - Improve the signel-connection
 check

When the connections from the pin selector contain only two
widgets, a route to DAC and the aa-mixer, it's certainly a
single connection.  In such a case, get_dac_if_single() should
return the connected DAC, too.

This will improve the detection of the individual DAC
assignment for each pin.

Subject: [PATCH 2237/6423] ALSA: hda/realtek - Finer tuning of auto-parser
 with badness evaluation

This patch improves the Realtek auto-parser for assigning the DACs and
mixers in more suitable ways by evaluating the assignment with "badness"
calculations.

When assigning a DAC hinders the assignment of individual DACs for
other pins, some badness point is given.  Similarly, when it blocks the
assignment of unique mixer controls, another badness point is added.
Also, if no DAC, even shared DAC, can be assigned, more badness is
pointed.  Finally, comparing the accumulated badness, the best route is
chosen among several trials.

From 185d99f1924ee0047bcd524c58a01c9f8d58d673 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Thu, 16 Feb 2012 18:39:45 +0100
Subject: [PATCH 2238/6423] ALSA: hda/realtek - Try harder to fit the
 single-connections

So far, the Realtek driver tires to assign the single-connected routes
for all pins only once at the beginning.  However, since some DACs have
been already mapped, the rest pins might have also single conections.

In this patch, the driver does the single-connection assignment in a
loop until all possbile single-connections are checked.  This will
improve the DAC assignment, e.g. for ASUS G72.

Subject: [PATCH 2239/6423] drm: move pci bus master enable into driver.

The current enabling of bus mastering in the drm midlayer allows a large
race condition under kexec. When a kexec'ed kernel re-enables bus mastering
for the GPU, previously setup dma blocks may cause writes to random pieces
of memory. On radeon the writeback mechanism can cause these sorts of issues.

This patch doesn't fix the problem, but it moves the bus master enable under
the individual drivers control so they can move enabling it until later in
their load cycle and close the race.

Fix for radeon kms driver will be in a follow-up patch.

Subject: [PATCH 2240/6423] drm: add some caps for userspace to discover more
 info for dumb KMS driver (v2)

For the simple KMS driver case we need some more info about what the preferred
depth and if a shadow framebuffer is preferred.

I've only added this for intel/radeon which support the dumb ioctls so far.

If you need something really fancy you should be writing a real X.org driver.

v2: drop cursor information, just return an error from the cursor ioctls
and we can make userspace fallback to sw cursor in that case, cursor
info was getting too messy, best to start smaller.

Subject: [PATCH 2241/6423] batman-adv: add tt_initialised flag to the
 orig_node struct

(ttvn == 0) is currently used as initial condition. However this is not a good
idea because ttvn gets the vale zero each time after reaching the maximum value
(wrap around). For this reason a new flag is added in order to define whether a
node has an initialised table or not. Moreover, after invoking
tt_global_del_orig(), tt_initialised has to be set to false

Subject: [PATCH 2242/6423] batman-adv: Explicitly mark the common header
 structure

All batman-adv packets have a common 3 byte header. It can be used to share
some code between different code paths, but it was never explicit stated that
this header has to be always the same for all packets. Therefore, new code
changes always have the problem that they may accidently introduce regressions
by moving some elements around.

A new structure is introduced that contains the common header and makes it
easier visible that these 3 bytes have to be the same for all on-wire packets.

Subject: [PATCH 2243/6423] batman-adv: simplify bat_ogm_receive API call

Most of the values in that call are derived from the skb, so we can hand
over the skb instead.

 general use
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both translation tables and network coding use timeouts to do house
keeping, so we might as well share the function used to compare a
timestamp+timeout with current time.

For readability and simplicity, the function is renamed to
has_timed_out() and uses time_is_before_jiffies() instead of
time_after().

From 032b7969f8874d5ddc65691cd3d008beffd2a09e Mon Sep 17 00:00:00 2001
From: Marek Lindner <lindner_marek@yahoo.de>
Date: Tue, 20 Dec 2011 19:30:40 +0800
Subject: [PATCH 2249/6423] batman-adv: convert time_after instances to
 has_timed_out

To increase readability the has_timed_out() functions has been introduced.
This patch converts existing time_after() calls to use this wrapper
function (if applicable).
This patch also converts all timeouts to miliseconds to be consistent.

Subject: [PATCH 2254/6423] batman-adv: set TT_CLIENT_NEW flag before invoking
 hash_add()

In case of a new tt_local_entry, the TT_CLIENT_NEW flag has to be set before
adding such entry to the hash table. Otherwise, it opens a race condition
in which the entry can be found but the flag has not been set.

Each tt_local_set_pending is always followed by a bat_dbg invocation. This can

Subject: [PATCH 2259/6423] SUNRPC: add sending,pending queue and max slot to
 xprt stats

With static RPC slots, the xprt backlog queue stats were useful in showing
when the transport (TCP) was starved by lack of RPC slots. The new dynamic
RPC slot code, commit d9ba131d8f58c0d2ff5029e7002ab43f913b36f9, always
provides an RPC slot and so only uses the xprt backlog queue when the
tcp_max_slot_table_entries value has been hit or when an allocation error
occurs. All requests are now placed on the xprt sending or pending queue which
need to be monitored for debugging.

The max_slot stat shows the maximum number of dynamic RPC slots reached which is
useful when debugging performance issues.

Add the new fields at the end of the mountstats xprt stanza so that mountstats
outputs the previous correct values and ignores the new fields. Bump
NFS_IOSTATS_VERS.

Subject: [PATCH 2260/6423] SUNRPC: Use KERN_DEFAULT for debugging printk's

Our dprintk() debugging facility doesn't specify any verbosity level
for it's printk() calls, but it should.

The default verbosity for printk's is KERN_DEFAULT.  You might argue
that these are debugging printk's and thus the verbosity should be
KERN_DEBUG.  That would mean that to see NFS and SUNRPC debugging
output an admin would also have to boost the syslog verbosity, which
would be insufferably noisy.

Subject: [PATCH 2263/6423] net: sh_eth: change the condition of initialization

The SH7757 has 2 Fast Ethernet and 2 Gigabit Ethernet, and the first
Gigabit channel needs the initialization. So, this patch adds the
parameter of "needs_init", and if the sh_eth_plat_data is set it
to 1, the driver will initialize the channel.

Subject: [PATCH 2266/6423] net: sh_eth: add support for VLAN tag filtering

Some controllers have TSU. It can register one VLAN tag, and it can
filter other VLAN tag by hardware.
If vlan_rx_add_vid() is called twice or more, the driver will disable
the filtering.

Subject: [PATCH 2282/6423] openrisc: enable passing of flattened device tree
 pointer

This patch enables passing a fdt pointer to the kernel.

This makes for the kernel parameter API:

void kernel(unsigned int fdt);

which, in accordance with the OpenRISC ABI results in:
r3 = pointer to fdt

Subject: [PATCH 2283/6423] OpenRISC: Don't reimplement force_sigsegv()

Instead of open coding the sequence from force_sigsegv() just call
it. This also fixes a bug because we were modifying ka->sa.sa_handler
(which is a copy of sighand->action[]), whereas the intention of the
code was to modify sighand->action[] directly.

As the original code was working with a copy it had no effect on
signal delivery.

Subject: [PATCH 2286/6423] OpenRISC: Use set_current_blocked() and
 block_sigmask()

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures. In the past some architectures got this
code wrong, so using this helper function should stop that from
happening again.

Subject: [PATCH 2288/6423] openrisc: Set shortest clock event to 100 ticks

It takes a couple of instructions to actually configure a clock event
so setting an alarm just 1 clock cycle in the future isn't going to work;
doing so results in setting an alarm in the "past" in which case the event
won't fire until the timer overflows and rolls back around to the "current
time".

Not quite sure how many clock cycles it actually takes to get through to
actually writing the register, but 100 seems to work reliably.

Use generic helper to set up the clock event while we're at it.

Subject: [PATCH 2291/6423] Bluetooth: mgmt: Add support for Set Link Security
 command

The Set Link Security mgmt command is used to enable or disable link
level security, also known as Security Mode 3. This is rarely enabled in
modern systems but the command needs to be available for completeness,
qualification purposes and those few systems that actually want to
enable it.

Use specific logging functions instead of a generic
bt_printk function can save some text.

Remove now unused bt_printk function.
Add compatibility BT_INFO and BT_ERR macros.

Subject: [PATCH 2302/6423] ALSA: hda/realtek - Adjust badness calculation for
 multi-ios

Try harder to fit the multi-io pins also by checking the hard-wired
connections for multi-ios.  Also, the badness values are adjusted to
prioritize the multi-ios as more valuable.  These changes will enable
the multi-io on some machines without losing the current capability.

From dc6af52dea5ada1269095cad5ed2c04e92114399 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Fri, 17 Feb 2012 16:18:59 +0100
Subject: [PATCH 2303/6423] ALSA: hda/realtek - Rewrite ALC880 model=lg with
 the auto-parser

ALC880 model=lg could work fine with the auto-parser due to the recent
rewrite, but it still needs the manual adjustment; namely, the BIOS leaves
unused pins as some real active jacks.  This confuses the parser.
Thus we just cover these pins and override the pin-configs as a fix-up.

Subject: [PATCH 2308/6423] ASoC: dapm: Supply the DAI and substream when
 calling stream events

In order to allow us to do something smarter than iterate through widgets
doing strcmp() to work out what to power up for stream events change the
interface used to generate them to be based on the combination of a DAI
and a stream direction rather than just a simple string identifying the
stream.

At some point we'll probably want a set of channels too.

Subject: [PATCH 2310/6423] ASoC: dapm: Implement and instantiate DAI widgets

In order to allow us to do smarter things with DAI links create DAPM
widgets which directly represent the DAIs in the DAPM graph. These are
automatically created from the DAIs as we probe the card with references
held in both directions between the widget and the DAI.

The widgets are not made available for direct instantiation by drivers,
they are created automatically from the DAIs.  Drivers should be updated
to create stream routes using DAPM maps rather than by annotating AIF
and DAC widgets with streams.

In order to ease transition to this model from existing drivers we
automatically create DAPM routes between the DAI widgets and the existing
stream widgets which are started and stopped by the DAI widgets, though
the old stream handling mechanism is still in place.  This also has the
nice effect of removing non-DAPM devices as any device with a DAI
acquires a widget automatically which will allow future simplifications
to the core DAPM logic.

The intention is that in future the AIF and DAI widgets will gain the
ability to interact such that we are able to manage activity on
individual channels independantly rather than powering up and down the
entire AIF as we do currently.

Currently we only generate these for CODECs, mostly as I have no systems
with non-CODEC DAPM to integrate with. It should be a simple matter of
programming to add the additional hookup for these.

This means we don't need to walk through every single widget in the system

Subject: [PATCH 2317/6423] ALSA: hda/realtek - Rewrite ALC880 model=w810 with
 auto-parser

The Medion W810 with ALC880 has a typical BIOS bug, copying the
pin-defaults without disabling the unused pins.  At least, the pin
0x17 must be disabled.  Also, it requires GPIO-2 setup.

Subject: [PATCH 2319/6423] ALSA: hda/realtek - Drop ALC880 model=clevo

Clevo machines with ALC880 are all well with proper BIOS setup.
It seems still requiring the additional COEF setup for the EAPD.

Subject: [PATCH 2321/6423] regmap: Bypassing cache when initializing cache

During regcache_init, if client has not passed the
default data of cached register then it is directly
read from the hw to initialize cache. This hw register
read happens before cache ops are initialized and hence
avoiding register read to check for the data available
on cache or not by enabling flag of cache_bypass.

Subject: [PATCH 2323/6423] PCI: Fix /sys warning when sriov enabled and card
 is hot removed

sysfs is a bit stricter now and emits warnings in more cases.

For SRIOV hotplug, we are calling pci_stop_dev() for each VF first
(after we update pci_stop_bus_devices) which remove each VF subdir.  So
double check the VF dir in /sys before trying to remove the physfn link.

Subject: [PATCH 2324/6423] PCI / PM: Disable wakeup during shutdown for
 devices not enabled to wake up

If a PCI device is enabled to generate wakeup signals (PME) when put
into a low-power state by runtime PM, it will be still enabled to
generate those signals after the system shutdown, unless its driver's
.shutdown() callback takes care of the wakeup signals generation
setting.  Moreover, there are devices that are not enabled to wake
up the system and that are configured by runtime PM to generate
wakeup signals so that (runtime) remote wakeup works with them.
Those devices should be reconfigured during system shutdown so that
they don't generate wakeup signals, but at least some drivers don't
do that.  However, that very well may be done by the PCI core so
that drivers don't have to worry about it.  For this reason, modify
pci_device_shutdown() to disable the generation of wakeup events for
devices not supposed to wake up the system.

From 6c55f5ed3a23ba60a0e7809a39ad7361ae00a764 Mon Sep 17 00:00:00 2001
From: Amit Beka <amit.beka@intel.com>
Date: Wed, 25 Jan 2012 13:30:27 +0200
Subject: [PATCH 2326/6423] iwlwifi: testmode new indirect RW API

Replaced the old SRAM and periphery indirect access functions
with a unified indirect memory access functions. These include
new IWL_TM_CMDs for buffer read/write/dump which replace the
SRAM read/dump commands, but the API for IWL_TM_CMD_INDIRECT_REG
read/write will now not be supported (returns error).

This also handles writing to periphery registers in 1-3 bytes.

Requires the corresponding patch in the library for the API change.

Subject: [PATCH 2327/6423] iwlwifi: added reply data to testmode HCMD send

The testmode command for host command send now replies
with a nl80211 message and the response it recieved from
the device.

This does not change the API directly, but adds a reply
to the testmode call.

Subject: [PATCH 2328/6423] iwlwifi: trace debug messages

Make iwlwifi record all debug messages into
tracing, even if debug_level is not enabled.
Due to the lack of APIs, the debug messages
are now recorded up to a max length of 100,
the only one above that is the RXON which is
not needed if you trace the commands as well
as it only dumps the command contents.

From 1ee158d83853a9f5c1465be56d56ff56e6698e92 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Fri, 17 Feb 2012 10:07:44 -0800
Subject: [PATCH 2329/6423] iwlwifi: move workqueue to priv

In order to separate the different parts of the
driver better, we are reducing the shared data.
This moves the workqueue to "priv", and removes
it from the transport. To do this, simply use
schedule_work() in the transport.

Subject: [PATCH 2330/6423] iwlwifi: give PCIe its own lock

Instead of using a global lock, the PCIe transport
can use an own lock for its IRQ. This will make it
possible to not disable IRQs for the shared lock.
The lock is currently used throughout the code but
this can be improved even further by splitting up
the locking for the queues.

From 655ccceb59f8fbffc2ed151d07d03eb88f27adb6 Mon Sep 17 00:00:00 2001
From: Don Fry <donald.h.fry@intel.com>
Date: Mon, 6 Feb 2012 16:37:46 -0800
Subject: [PATCH 2337/6423] iwlwifi: change args to ucode routines

Change the prameters to the ucode (de)allocate routines to iwl_nic as
they are not transport operations.

Subject: [PATCH 2338/6423] iwlwifi: kill iwl_down and s/__iwl_down/iwl_down

iwl_down was just a wrapper around __iwl_down which was called from
one place only. Replace it to direct call to iwl_down. Add lockdep
warning in iwl_down to ensure it was called with the mutex held.

Subject: [PATCH 2344/6423] iwlwifi: send testmode hcmd reply with rx header

When a host command is sent through testmode, the whole
reply (including rx header) is returned to the user, and not
only the payload of the rx.
Before this commit the length was buggy - the reply contained 4 bytes
after the end of the payload.

Subject: [PATCH 2347/6423] iwlwifi: the transport knows its state

This allows to handle races such as Tx packets on their way to be
sent although the transport has been stopped already.

Subject: [PATCH 2352/6423] iwlwifi: enable receiving beacons when not
 associated

If the firmware implements beacon filtering,
beacons are filtered when not associated. This causes
association failures on channels marked passive.

Enabling this flag indicates to the firmware to allow
the beacons to pass through when not associated only.

Fix error handling in atl1c_probe(). If atl1c_read_mac_addr()
couldn't get the hw mac address, and a random mac address get
set return the error code. Don't go to err_eeprom in
atl1c_probe(), use the generated MAC address in this case.

pm_suspend() instead of it, so make that happen (which also reduces
code duplication related to suspend statistics).

Subject: [PATCH 2369/6423] PM: Add comment describing relationships between PM
 callbacks to pm.h

The UNIVERSAL_DEV_PM_OPS() macro is slightly misleading, because it
may suggest that it's a good idea to point runtime PM callback
pointers to the same routines as system suspend/resume callbacks
.suspend() and .resume(), which is not the case.  For this reason,
add a comment to include/linux/pm.h, next to the definition of
UNIVERSAL_DEV_PM_OPS(), describing how device PM callbacks are
related to each other.

Subject: [PATCH 2371/6423] regmap: Add stub regmap calls as a build crutch for
 infrastructure users

Make life easier for subsystems which build infrastructure on top of the
regmap API by providing stub definitions for most of the API so that users
can at least build even if the regmap API is not enabled without having to
add ifdefs if they don't want to.

These stubs are not expected to be useful and should never actually get
called, they just exist so that we can link so there are WARN_ONCE()s in
the stubs.

 always set

Currently, the nfs_parsed_mount_data->net field is initialised in
the nfs_parse_mount_options() function, which means that it only
gets set if we're using text based mounts. The legacy binary
mount interface is therefore broken.

Fix is to initialise the ->net field in nfs_alloc_parsed_mount_data.

This patch does some code refactoring in start_discovery function
in order to prepare it for interleaved discovery support.

MGMT_ADDR_* macros were moved to hci_core.h since they are now used
to define discovery type macros.

Discovery type macros were defined according to mgmt-api.txt
specification:

Possible values for the Type parameter are a bit-wise or of the
following bits:

	1	BR/EDR
	2	LE Public
	3	LE Random

By combining these e.g. the following values are possible:

	1	BR/EDR
	6	LE (public & random)
	7	BR/EDR/LE (interleaved discovery)

Subject: [PATCH 2379/6423] Bluetooth: Merge INQUIRY and LE_SCAN discovery
 states

This patch merges DISCOVERY_INQUIRY and DISCOVERY_LE_SCAN states
into a new state called DISCOVERY_FINDING.

From the discovery perspective, we are pretty much worried about
to know just if we are finding devices than what exactly phase of
"finding devices" (inquiry or LE scan) we are currently running.
Besides, to know if the controller is performing inquiry or LE scan
we should check HCI_INQUIRY or HCI_LE_SCAN bits in hdev flags.

Moreover, merging this two states will simplify the discovery state
machine and will keep interleaved discovery implementation simpler.

Subject: [PATCH 2380/6423] Bluetooth: Interleaved discovery support

This patch adds interleaved discovery support to MGMT Start
Discovery command.

In case interleaved discovery is not supported (not a dual mode
device), we perform BR/EDR or LE-only discovery according to the
device capabilities.

Instead of having status paramters part of each individual command
response it's simpler to just have the status as part of the command
complete header. This patch updates the code to follow this convention
and thereby also ensures compliance with the latest mgmt API

Subject: [PATCH 2387/6423] Bluetooth: mgmt: Bump mgmt version

This patch bumps the mgmt version to 1 and resets the revision to 0.
This is in order to indicate API stability to user space. The mgmt API
has reached a point where no major backwards incompatible changes are
expected so it makes sense to do this version bump now.

Subject: [PATCH 2388/6423] Bluetooth: Fix hci_connect error return values

The hci_connect function should either return a valid hci_conn pointer
or a ERR_PTR() but never NULL. This patch fixes the two places where
hci_conn_add failures would have caused a NULL return. The only reason
for failure with hci_conn_add is memory allocation so ENOMEM seems to be
a good choice here.

Subject: [PATCH 2390/6423] [SCSI] pm8001: fix lockup on phy_control hard
 reset.

pm8001_phy_control PHY_FUNC_HARD_RESET locks up on second try via
smp_phy_control because response HW_EVENT_PHY_START_STATUS fails to complete
previous command. The PM8001F_RUN_TIME flag is not treated as a bit, but a
state in all readers, yet once we are operational or in the run time state,
the flags use a bit-set operation.

Subject: [PATCH 2391/6423] [SCSI] pm8001: Add FUNC_GET_EVENTS

Jack noticed I dropped a patch fragment associated with a flags automatic
variable in mpi_set_phys_g3_with_ssc (ooops) and that the pre-emptive locking
that piggy-backed this patch was not in-fact necessary because of underlying
atomic accesses to the hardware. Here is the updated patch fixing these two
issues.

The pm8001 driver is missing the FUNC_GET_EVENTS handler in the phy control
function. Since the pm8001_bar4_shift function was not designed to be called
at runtime, added locking surrounding the adjustment for all accesses.

Subject: [PATCH 2392/6423] [SCSI] pm8001: deficient responses to
 IO_XFER_ERROR_BREAK and IO_XFER_OPEN_RETRY_TIMEOUT

IO_XFER_ERROR_BREAK and IO_XFER_OPEN_RETRY_TIMEOUT are deficient of the
required actions as outlined in the programming manual for the pm8001. Due to
the overlapping code requirements of these recovery responses, we found it
necessary to bundle them together into one patch.

When a break is received during the command phase (ssp_completion), this is a
result of a timeout or interruption on the bus. Logic suggests that we should
retry the command.

When a break is received during the data-phase (ssp_event), the task must be
aborted on the target or it will retain a data-phase lock turning the target
reticent to all future media commands yet will successfully respond to TUR,
INQUIRY and ABORT leading eventually to target failure through several
abort-cycle loops.

The open retry interval is exceedingly short resulting in occasional target
drop-off during expander resets or when targets push-back during bad-block
remapping. Increased effective timeout from 130ms to 1.5 seconds for each try
so as to trigger after the administrative inquiry/tur timeout in the scsi
subsystem to keep error-recovery harmonics to a minimum.

When an open retry timeout event is received, the action required by the
targets is to issue an abort for the outstanding command then logic suggests
we retry the command as this state is usually an indication of a credit block
or busy condition on the target.

We hijacked the pm8001_handle_event work queue handler so that it will handle
task as an argument instead of device for the workers in support of the
deferred handling outlined above.

Moderate to Heavy bad-path testing on a 2.6.32 vintage kernel, compile-testing
on scsi-misc-2.6 kernel ...

Subject: [PATCH 2406/6423] [SCSI] hpsa: removed unneeded structure member
 max_sg_entries and fix badly named constant MAXSGENTRIES

We had both h->max_sg_entries and h->maxsgentries in the per controller
structure which is terribly confusing.  max_sg_entries was really
just a constant, 32, which defines how big the "block fetch table"
is, which is as large as the max number of SG elements embedded
within a command (excluding SG elements in chain blocks).

MAXSGENTRIES was the constant used to denote the max number of SG
elements embedded within a command, also a poor name.

So renamed MAXSGENTREIS to SG_ENTRIES_IN_CMD, and removed
h->max_sg_entries and replaced it with SG_ENTRIES_IN_CMD.

h->maxsgentries is unchanged, and is the maximum number of sg
elements the controller will support in a command, including
those in chain blocks, minus 1 for the chain block pointer..

Subject: [PATCH 2407/6423] [SCSI] hpsa: combine hpsa_scsi_detect and
 hpsa_register_scsi

hpsa_register_scsi just calls hpsa_scsi_detect.  Move
the guts of hpsa_scsi_detect into hpsa_register_scsi and
get rid of hpsa_scsi_detect.

Subject: [PATCH 2408/6423] [SCSI] hpsa: factor out driver name

Sometimes, for testing purposes (e.g. testing rmmod on a system
that normally boots using hpsa) it's nice to rename the driver
and split it into two drivers and restrict it to certain
controllers.  This makes that easier.

Subject: [PATCH 2409/6423] [SCSI] hpsa: Fix problem with MSA2xxx devices

Upgraded firmware on Smart Array P7xx (and some others) made them show up as
SCSI revision 5 devices and this caused the driver to fail to map MSA2xxx
logical drives to the correct bus/target/lun.  A symptom of this would be that
the target ID of the logical drives as presented by the external storage array
is ignored, and all such logical drives are assigned to target zero,
differentiated only by LUN.  Some multipath software reportedly does not deal
well with this behavior, failing to recognize different paths to the same
device as such.

Subject: [PATCH 2410/6423] [SCSI] hpsa: make target and lun match what SCSI
 REPORT LUNs returns

Some distros have a "rescan-scsi-bus.sh" script which depends on
SCSI REPORT LUNs not reporting something different than what the
driver tells the kernel, even if the driver uses scan_start and
scan_finished methods of the SCSI host template to override the
usual SCSI midlayer discovery code.  Previously, 1 was added to
the LUN to make room to insert the RAID controller device at
LUN 0.  Now, the RAID controller is moved to bus 3, and 1 is no
longer added to the LUN.  However, SCSI REPORT LUNS on Smart Array
doesn't report physical devices like tape drives or auto-loaders
as it turns out, so those particular device types still won't match.
Generally the logical drives are reported first however, so at
least those should match.

Subject: [PATCH 2412/6423] [SCSI] hpsa: eliminate 8 external target limitation

Driver limits SAS external target IDs to range 1-8.
Need to increase limit and clean up overlapping concepts of targets and paths
in the code.

There are several defined constants that control this:
HPSA_MAX_TARGETS_PER_CTLR     16
MAX_MSA2XXX_ENCLOSURES        32
HPSA_MAX_PATHS                8

We can condense this to one constant:
MAX_EXT_TARGETS               32

SAS switches allow for 8 connections, and there is capacity for 4 switches per
enclosure in largest blade enclosure type.

Subject: [PATCH 2414/6423] [SCSI] hpsa: update device attributes when they
 change

Certain types of changes to devices should not be interpreted as a device
change that would cause the device to be removed and re-added.  These include
RAID level and Firmware revision changes.  However, these attribute changes DO
need to be reflected in the controller info structure's dev structure list, so
that sysfs and /proc info files for the devices will reflect the new values.

Subject: [PATCH 2415/6423] [SCSI] scsi_debug: GET LBA STATUS response length
 correction

The SCSI GET LBA STATUS command was introduced in SBC-3 revision
20 in September 2009. At that time the Parameter Data Length
field in the response had an associated byte offset of 8.

Then in SBC-3 revision 25 (October 2010) that byte offset was
changed to 4. The sg_get_lba_status utility in sg3_utils version
1.33 (released earlier today) has been changed to calculate
the newer response length. However the implementation of
GET LBA STATUS command in the scsi_debug driver still uses the
original byte offset.

modify the Parameter Data Length field value in the GET LBA STATUS command
response to comply with the change in SBC-3 revision 25

This patch brings them in sync to these specifications.

The values are converted to strings when represented via
sysfs attribute, hence that should cover for user space
apps as they may not see any change.

From d78c317f6cd701bda9f6dbfbfbcba72f39dd6ad7 Mon Sep 17 00:00:00 2001
From: Neerav Parikh <neerav.parikh@intel.com>
Date: Sun, 22 Jan 2012 17:30:05 -0800
Subject: [PATCH 2420/6423] [SCSI] libfc: Add support for FDMI

This patch adds support for Fabric Device Management
Interface as per FC-GS-4 spec. in libfc. Any driver
making use of libfc can enable fdmi state machine
for a given lport.

If lport has enabled FDMI support the lport state
machine will transition into FDMI after completing
the DNS states and before entering the SCR state.
The FDMI state transition is such that if there is an
error, it won't stop the lport state machine from
transitioning and the it will behave as if there was
no FDMI support.

The FDMI HBA attributes are registed with the Management
server via Register HBA (RHBA) command and the port
attributes are reigstered using the Register Port(RPA)
command.

Host drops sessions when flood of unsolicited LOGOs are received from the

of 3, the target sessions are dropped. Increased the retry count to 255 to
allow sufficient retries in this scenario.

Subject: [PATCH 2425/6423] [SCSI] bnx2fc: NPIV ports go offline when interface
 is brought down & up

When there are 255 NPIV ports, and the interface is brought down & up, both
physical and NPIV ports are logged off and never logged back in. Since
discovery happens on single CPU, XID resources on that CPU will be limited,
which when exhausted the discovery fails. Increase the XID resource range to
ensure that the discovery completes successfully. Also ensure that
fc_exch_mgr_alloc() doesn't fail on the system that has lower number of CPUs.

Subject: [PATCH 2427/6423] [SCSI] Correctly set the scsi host/msg/status bytes

Resubmitting as my previous post had format issues and did not go llinux-scsi.
This patch changes the function to set_msg_byte, set_host_byte and
set_driver_byte to correctly set the corresponding bytes appropriately.

It will reset the original setting and correctly set it to the new value.  The
previous OR operation does not always set it back to new value. Look at patch
2/2 for an example.

Subject: [PATCH 2428/6423] [SCSI] fix the new host byte settings
 (DID_TARGET_FAILURE and DID_NEXUS_FAILURE)

This patch fixes the host byte settings DID_TARGET_FAILURE and
DID_NEXUS_FAILURE.  The function __scsi_error_from_host_byte, tries to reset
the host byte to DID_OK. But that does not happen because of the OR operation.

Here is the flow.

scsi_softirq_done-> scsi_decide_disposition -> __scsi_error_from_host_byte

Let's take an example with DID_NEXUS_FAILURE. In scsi_decide_disposition,
result will be set as DID_NEXUS_FAILURE (=0x11). Then in
__scsi_error_from_host_byte, when we do OR with DID_OK.  Purpose is to reset
it back to DID_OK. But that does not happen.  This patch fixes this issue.

Subject: [PATCH 2430/6423] [SCSI] iscsi: fix setting of pid from netlink skb

NETLINK_CREDS's pid now returns 0, so I guess we are supposed to
be using NETLINK_CB. This changed while the patch to export the
pid was getting merged upstream, so it was not noticed until both
the network and iscsi changes were in the same tree.

Subject: [PATCH 2432/6423] [SCSI] libiscsi: fix cmd timeout/completion race

If the driver/lib has called scsi_done and cleaned up internally but
scsi layer has not yet called blk_mark_rq_complete when the command
times out we hit a problem if the timeout code calls blk_mark_rq_complete first.
When the time out code calls into the driver we were returning
BLK_EH_RESET_TIMER and that causes the timeout code to just call
us again later.

We need to be calling BLK_EH_HANDLED so the timeout code can complete
the completion process because it had called blk_mark_rq_complete
on the command and now owns its processing.

Subject: [PATCH 2434/6423] [SCSI] bfa: don't leak mem in
 bfad_im_bsg_els_ct_request()

If 'drv_fcxp = kzalloc(sizeof(struct bfad_fcxp), GFP_KERNEL);' fails
and returns NULL, then we'll leak the memory allocated to 'bsg_fcpt'
when we jump to 'out:' and the variable subsequently goes out of
scope.

Also remove the cast of the kzalloc() return value. kzalloc() returns
a void* which is implicitly converted, so the explicit cast is
pointless.

Subject: [PATCH 2437/6423] [SCSI] bnx2i: Fixed the override of the error_mask
 module param

The error_mask module param overrides has a bug which prevented
the new module param values to take effect.

Also changed the type attribute of the error_mask1/2 module params
from int to uint to allow the MSB to be set.

Subject: [PATCH 2443/6423] [SCSI] qla2xxx: Use consistent DL mask for ELS/CT
 passthru requests.

The driver is logging a slew of 'good' status requests for ELS/CT passthrough
commands.  Change some log messages from:

     * ql_log() -> ql_dbg()
     * ql_log_info -> ql_dbg_user

Subject: [PATCH 2446/6423] [SCSI] qla2xxx: Return blank sysfs string on
 initial get thermal failure.

When thermal temperature initially fails, return a blank string to the
sysfs interface.  This fixes the initial display of 0.00 followed by
subsequent display of blank line; the initial 0.00 should have not
displayed for cards that do not support thermal temperature.

Subject: [PATCH 2449/6423] [SCSI] qla2xxx: Perform implicit logout during
 rport tear-down.

During rport tear-down, make sure we do an implicit LOGO of the fcport in our
firmware to try to clear any residual commands associated with that fcport.

Subject: [PATCH 2450/6423] [SCSI] qla2xxx: Prep zero-length BSG data-transfer

During command failure/non-recognition, the upper-layer
FC-transport expects the drivers to set
job-reply->reply_payload_rcv_len.  Do this in a consistent manner
to avoid duplication.

Subject: [PATCH 2462/6423] [SCSI] qla2xxx: Cache swl during fabric discovery.

Rather than continuously allocating and freeing swl within the discovery
process, simply pre-allocate it the first time that it's needed, cache it
through the rest of the lifecycle of the driver and free it at module unload.

From 0eba25df2190f191cb92879b225a0e484c3e5b51 Mon Sep 17 00:00:00 2001
From: Arun Easi <arun.easi@qlogic.com>
Date: Thu, 9 Feb 2012 11:15:58 -0800
Subject: [PATCH 2464/6423] [SCSI] qla2xxx: Handle device mapping changes due
 to device logout.

A device logout sent in the delete path of a fcport would clear the
port handle binding inside the firmware. This could lead to queued
work items for the fcport, if any, getting incorrect results. This
patch fixes the issue by checking for device name changes after a
call to get port database.

This allows the controller to do WRITE_INSERT and READ_STRIP for SAS
disks that support protection information. SAS disks must be formatted
with protection information to use this feature via sg_format.

  sg3_utils-1.32 -- sg_format version 1.19 20110730
  sg_format usage:
  sg_format --format --verbose --pinfo /dev/sda

Subject: [PATCH 2469/6423] [SCSI] libfcoe: Don't KERN_ERR on netdev
 notification

This is more of a debug statement. As a KERN_ERR we generate
log entries anytime any netdev goes up or down, so when booting
there are notification log entries for all system interfaces
including 'lo'. This is too much. Let's just log when necessary.

Subject: [PATCH 2471/6423] [SCSI] fcoe: Rename out_nomod label to out_putmod

The label implies that it should be called when
there is 'nomod.' I read that to mean that the
module reference 'get' failed. However, it's only
called when the module reference 'get' succeeded.

I think it makes more sense to name the label,
'out_putmod' since it should be called when we
need to 'put' the module reference taken in the
routine before returning.

Subject: [PATCH 2472/6423] [SCSI] fcoe: Do not switch context in vport_delete
 callback

Currently all port deletion is routed though the FCoE
workqueue (fcoe_wq). When fc_remove_host is called on
an N_Port (for example, from fcoe_destroy) the vports
are queued into a FC Transport workqueue. fc_remove_host
flushes that queue and each vport is passed to fcoe's
fcoe_vport_destroy, which simply queues the associated
fcoe_ports for later deletion. This queue cannot be
flushed within the N_Ports destroy path because of
circular locking issues. The result is that the NPIV
ports are destroyed after the N_Port, which is reverse
of how they are created.

This quirk causes fcoe to keep references on the
fcoe_interface shared by each of these ports (N_Port
and NPIV). Changing the ordering such that NPIV ports
are destroyed before the N_Port will allow us to remove
reference counting on the fcoe_interface instances.

This patch simply allows fcoe_vport_destory to destroy
NPIV ports without deferring them to a workqueue context.
This ensures that when fc_remove_host is called the
NPIV ports will be destroyed first before the N_Port and
allows reference counting on the fcoe's fcoe_interface
to be remove in a later patch.

Subject: [PATCH 2474/6423] [SCSI] libfc: Fix panic in fc_exch_recv

Adding and removing the host into the zone causes this panic.

BUG: unable to handle kernel NULL pointer dereference at 00000000000000a0
IP: [<ffffffffa0491707>] fc_exch_recv+0xc57/0xe70 [libfc]

During fc_exch_reset, the active exchanges are aborted and the exch is deleted.
As part of processing ABTS response, due to 'ep' being NULL, any access to ep in
fc_exch_recv_bls() causes this panic. Fixed to access 'ep' only if non-NULL.

Subject: [PATCH 2475/6423] [SCSI] libfc: Handle discovery failure during ctlr
 link down

While we wait for GPN_FT response, if the ctlr link goes down, the stack
generates a completion for GPN_FT with error FC_EXCH_CLOSED, and reports a
discovery error. Discovery is not retried in this case, and rightly so.
However, the 'pending' flag stays set, which does not allow subsequent
discovery to succeed as GPN_FT will never be issued. Fix it by clearing the
pending flag when the discovery fails due to GPN_FT failure.

Subject: [PATCH 2479/6423] [SCSI] qla4xxx: Modified debug log messages for
 boot info.

In some configurations user may not have boot targets configured.
In such cases the debug messages printed out by driver look like
some kind of failure happening. However this could be a valid
case, so modified the messages to appear as warning messages
versus failure messages.

Return -EREMOTEIO so multipathing does not classify this condition as a

Subject: [PATCH 2492/6423] [SCSI] virtio-scsi: SCSI driver for QEMU based
 virtual machines

The virtio-scsi HBA is the basis of an alternative storage stack
for QEMU-based virtual machines (including KVM).  Compared to
virtio-blk it is more scalable, because it supports many LUNs
on a single PCI slot), more powerful (it more easily supports
passthrough of host devices to the guest) and more easily
extensible (new SCSI features implemented by QEMU should not
require updating the driver in the guest).

Subject: [PATCH 2494/6423] [SCSI] Handle disk devices which can not process
 medium access commands

We have experienced several devices which fail in a fashion we do not
currently handle gracefully in SCSI. After a failure these devices will
respond to the SCSI primary command set (INQUIRY, TEST UNIT READY, etc.)
but any command accessing the storage medium will time out.

The following patch adds an callback that can be used by upper level
drivers to inspect the results of an error handling command. This in
turn has been used to implement additional checking in the SCSI disk
driver.

If a medium access command fails twice but TEST UNIT READY succeeds both
times in the subsequent error handling we will offline the device. The
maximum number of failed commands required to take a device offline can
be tweaked in sysfs.

Also add a new error flag to scsi_debug which allows this scenario to be
easily reproduced.

Subject: [PATCH 2498/6423] [SCSI] libsas: fix domain_device leak

Arrange for the deallocation of a struct domain_device object when it no
longer has:
1/ any children
2/ references by any scsi_targets
3/ references by a lldd

The comment about domain_device lifetime in
Documentation/scsi/libsas.txt is stale as it appears mainline never had
a version of a struct domain_device that was registered as a kobject.
We now manage domain_device reference counts on behalf of external
agents.

These are never freed in the nominal path.  A domain_device has a
different lifetime than a sas_rphy we need a dev->rphy independent way
of identifying sata devices.

Subject: [PATCH 2502/6423] [SCSI] libsas: introduce sas_drain_work()

When an lldd invokes ->notify_port_event() it can trigger a chain of libsas
events to:

  1/ form the port and find the direct attached device

  2/ if the attached device is an expander perform domain discovery

A call to flush_workqueue() will only flush the initial port formation work.
Currently libsas users need to call scsi_flush_work() up to the max depth of
chain (which will grow from 2 to 3 when ata discovery is moved to its own
discovery event).  Instead of open coding multiple calls switch to use
drain_workqueue() to flush sas work.

drain_workqueue() does not handle new work submitted during the drain so
libsas needs a bit of infrastructure to hold off unchained work submissions
while a drain is in flight.  A lldd ->notify() event is considered 'unchained'
while a sas_discover_event() is 'chained'.  As Tejun notes:

  "For now, I think it would be best to add private wrapper in libsas to
   support deferring unchained work items while draining."

Subject: [PATCH 2503/6423] [SCSI] libsas: remove ata_port.lock management
 duties from lldds

Each libsas driver (mvsas, pm8001, and isci) has invented a different
method for managing the ap->lock.  The lock is held by the ata
->queuecommand() path.  mvsas drops it prior to acquiring any internal
locks which allows it to hold its internal lock across calls to
task->task_done().  This capability is important as it is the only way
the driver can flush task->task_done() instances to guarantee that it no
longer has any in-flight references to a domain_device at
->lldd_dev_gone() time.

Subject: [PATCH 2505/6423] [SCSI] libsas: prevent domain rediscovery competing
 with ata error handling

libata error handling provides for a timeout for link recovery.  libsas
must not rescan for previously known devices in this interval otherwise
it may remove a device that is simply waiting for its link to recover.
Let libata-eh make the determination of when the link is stable and
prevent libsas (host workqueue) from taking action while this
determination is pending.

Using a mutex (ha->disco_mutex) to flush and disable revalidation while
eh is running requires any discovery action that may block on eh be
moved to its own context outside the lock.  Probing ATA devices
explicitly waits on ata-eh and the cache-flush-io issued during device
removal may also pend awaiting eh completion.  Essentially any rphy
add/remove activity needs to run outside the lock.

This adds two new cleanup states for sas_unregister_domain_devices()
'allocated-but-not-probed', and 'flagged-for-destruction'.  In the
'allocated-but-not-probed' state  dev->rphy points to a rphy that is
known to have not been through a sas_rphy_add() event.  At domain
teardown check if this device is still pending probe and cleanup
accordingly.  Similarly if a device has already been queued for removal
then sas_unregister_domain_devices has nothing to do.

From b91bb296188118eea9fdc6093cfcf76bbe8589ba Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Thu, 17 Nov 2011 17:59:52 -0800
Subject: [PATCH 2506/6423] [SCSI] libsas: use ->set_dmamode to notify lldds of
 NCQ parameters

sas_discover_sata() notifies lldds of sata devices twice.  Once to allow
the 'identify' to be sent, and a second time to allow aic94xx (the only
libsas driver that cares about sata_dev.identify) to setup NCQ
parameters before the device becomes known to the midlayer.  Replace
this double notification and intervening 'identify' with an explicit
->lldd_ata_set_dmamode notification.  With this change all ata internal
commands are issued by libata, so we no longer need sas_issue_ata_cmd().

The data from the identify command only needs to be cached in one
location so ata_device.id replaces domain_device.sata_dev.identify.

Subject: [PATCH 2507/6423] [SCSI] libsas: kill invocation of
 scsi_eh_finish_cmd from sas_ata_task_done

Prior to the conversion to the new-style libata-eh sas_ata_task_done()
may have been the last opportunity to clean up the scmd, but now
libata-eh explicitly handles this case.  It also races against sas-eh.
If a lldd completes a task after SAS_TASK_STATE_ABORTED is set it could
trigger a spurious decrement of shost->host_failed.  Current lldds have
the band-aid of checking SAS_TASK_STATE_ABORTED before calling
->task_done(), but better to just let the scmds escalate to libata for
race free cleanup.

Subject: [PATCH 2508/6423] [SCSI] libsas: close error handling vs
 sas_ata_task_done() race

Since sas_ata does not implement ->freeze(), completions for scmds and
internal commands can still arrive concurrent with
ata_scsi_cmd_error_handler() and sas_ata_post_internal() respectively.
By the time either of those is called libata has committed to completing
the qc, and the ATA_PFLAG_FROZEN flag tells sas_ata_task_done() it has
lost the race.

In the sas_ata_post_internal() case we take on the additional
responsibility of freeing the sas_task to close the race with
sas_ata_task_done() freeing the the task while sas_ata_post_internal()
is in the process of invoking ->lldd_abort_task().

 from eh
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We invoke task->task_done() to free the task in the eh case, but at this
point we are prepared for scsi_eh_flush_done_q() to finish off the scmd.

Introduce sas_end_task() to capture the final response status from the
lldd and free the task.

Also take the opportunity to kill this warning.
drivers/scsi/libsas/sas_scsi_host.c: In function ‘sas_end_task’:

Subject: [PATCH 2510/6423] [SCSI] libsas: fix timeout vs completion race

Until we have told the lldd to forget a task a timed out operation can
return from the hardware at any time.  Since completion frees the task
we need to make sure that no tasks run their normal completion handler
once eh has decided to manage the task.  Similar to
ata_scsi_cmd_error_handler() freeze completions to let eh judge the
outcome of the race.

Task collector mode is problematic because it presents a situation where
a task can be timed out and aborted before the lldd has even seen it.
For this case we need to guarantee that a task that an lldd has been
told to forget does not get queued after the lldd says "never seen it".
With sas_scsi_timed_out we achieve this with the ->task_queue_flush
mutex, rather than adding more time.

Subject: [PATCH 2511/6423] [SCSI] libsas: let libata handle command timeouts

libsas-eh if it successfully aborts an ata command will hide the timeout
condition (AC_ERR_TIMEOUT) from libata.  The command likely completes
with the all-zero task->task_status it started with.  Instead, interpret
a TMF_RESP_FUNC_COMPLETE as the end of the sas_task but keep the scmd
around for libata-eh to handle.

Subject: [PATCH 2512/6423] [SCSI] libsas: defer SAS_TASK_NEED_DEV_RESET
 commands to libata

lldds use the SAS_TASK_NEED_DEV_RESET interface to request that eh
perform a reset.  In the sata device case defer the commands that
triggered the reset to libata-eh context so it can perform its pre and
post reset management.

In the sas_ata_post_internal() case the reset request is falling on deaf
ears as the sas_task is immediately destroyed without any reset action.
Since it is currently a nop, and likely superfluous given the conversion
to new-style libata-eh, just drop the request.

Subject: [PATCH 2513/6423] [SCSI] libsas: use libata-eh-reset for sata
 rediscovery fis transmit failures

Since sata devices can take several seconds to recover the link on reset
the 0.5 seconds that libsas currently waits may not be enough.  Instead
if we are rediscovering a phy that was previously attached to a sata
device let libata handle any resets to encourage the device to transmit
the initial fis.

Once sas_ata_hard_reset() and lldds learn how to honor 'deadline' libsas
should stop encountering phys in an intermediate state, until then this
will loop until the fis is transmitted or ->attached_sas_addr gets
cleared, but in the more likely initial discovery case we keep existing
behavior.

 shost->workq context

Extend the sas transport class to allow transport users to attach extra
data to a sas_phy (->hostdata).  Use this area in libsas to move resets
to workq context in preparation for scheduling ata device resets through
libata-eh.

Subject: [PATCH 2515/6423] [SCSI] libsas: execute transport link resets with
 libata-eh via host workqueue

Link resets leave ata affiliations intact, so arrange for libsas to make
an effort to avoid dropping the device due to a slow-to-recover link.
Towards this end carry out reset in the host workqueue so that it can
check for ata devices and kick the reset request to libata.  Hard
resets, in contrast, bypass libata since they are meant for associating
an ata device with another initiator in the domain (tears down
affiliations).

Need to add a new transport_sas_phy_reset() since the current
sas_phy_reset() is a utility function to libsas lldds.  They are not
prepared for it to loop back into eh.

Subject: [PATCH 2517/6423] [SCSI] libsas: Remove redundant phy state
 notification calls.

In the case of an explicit sas_phy_enable call to disable a phy,
the LLDD provides the calls to sas_phy_disconnected and the
PHYE_LOSS_OF_SIGNAL event.

NOTE: This assumes that the lldd(s) generate the notification, which
appears to be the case, but only verfied on isci.

Subject: [PATCH 2519/6423] [SCSI] libsas: async ata-eh

Once sas_ata_hard_reset() starts honoring the 'deadline' parameter a
pathological configuration could take 25 seconds per ata device
(serialized) to recover.  Run per-port recoveries in parallel.

Subject: [PATCH 2520/6423] bnx2x: make bnx2x_close() static again

Commit 8304859a "bnx2x: add fan failure event handling" made the function
bnx2x_close() non-static unnecessarily. The function is not called from
other sources. Make it static again.

Subject: [PATCH 2522/6423] arch/blackfin: don't generate random mac in
 bfin_get_ether_addr()

Changed bfin_get_ether_addr() to return a state and to
set no random mac address if the board don't provide one.

Let the caller of bfin_get_ether_addr() set a random mac
address if the return value is not 0.

v2: don't set random mac in bfin_get_ether_addr()

Subject: [PATCH 2523/6423] adi: adapt to eth_hw_addr_random() and changes in
 arch/blackfin

Adapt adi ethernet driver to changes in bfin_get_ether_addr()
from arch/blackfin. bfin_get_ether_addr() returns now a state.
Set a random mac address via new eth_hw_addr_random() in case
the return value is not 0.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: change the logic to reduce unneeded checks

Subject: [PATCH 2524/6423] ASoC: Add __devinit annotation for
 pxa2xx_ac97_probe

This fixes below build warning:
WARNING: vmlinux.o(.text+0x1e632c): Section mismatch in reference from the function pxa2xx_ac97_probe() to the function .devinit.text:pxa2xx_ac97_hw_probe()
The function pxa2xx_ac97_probe() references
the function __devinit pxa2xx_ac97_hw_probe().
This is often because pxa2xx_ac97_probe lacks a __devinit
annotation or the annotation of pxa2xx_ac97_hw_probe is wrong.

Also rename pxa_ac97_dai to pxa_ac97_dai_driver to fix below build warning:

  LD      sound/soc/pxa/built-in.o
WARNING: sound/soc/pxa/built-in.o(.data+0x18c): Section mismatch in reference from the variable pxa_ac97_dai to the function .devinit.text:pxa2xx_ac97_probe()
The variable pxa_ac97_dai references
the function __devinit pxa2xx_ac97_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Subject: [PATCH 2525/6423] ASoC: fsi: Add DMAEngine support

This patch supports DMAEngine to FSI driver.
It supports only Tx case at this point.
If platform/cpu doesn't support DMAEngine, FSI driver will
use PIO transfer.

This patch fixes enic_probe to do a fw init devcmd for sriov vfs.
This enables vf driver in the guest to get into adapter init state without
having to explicitly issue an init fw cmd with portprofile info. But a

Subject: [PATCH 2532/6423] x86/UV: Lower UV rtc clocksource rating

Lower the rating of the UV rtc clocksource to just below that of
the tsc, to improve performance.

Reading the tsc clocksource has lower latency than reading the
rtc, so favor it in situations where it is synchronized and
stable.  When the tsc is unsynchronized, the rtc needs to be the
chosen clocksource.

The bt_cb(skb)->channel was only needed to make hci_send_to_sock() be
used for HCI raw and control sockets. Since they have now separate sending
functions this is no longer needed.

Subject: [PATCH 2539/6423] Bluetooth: Fix issue with shared SKB between HCI
 raw socket and driver

Any HCI raw socket gets a copy of each SKB that is either received or
send via the Bluetooth subsystem. The raw socket uses SKB clones to
send out data, but the problem is that it needs to add an extra packet
type byte in front of it. And some drivers need to also add an extra
header before submitting the packet.

So far this all worked magically fine since all of the drivers and the
raw sockets are adding the same byte at the same location. But that is
by pure coincidence. Since the data of cloned SKBs is shared, this means
that the raw socket and driver kept writing into the shared data area.

To fix this the only safe way is if the HCI raw socket creates a copy of
the SKB before sending it out. To not always copy all SKBs around, the
copy is only created once and only after any of the HCI filter checks
succeeded.

Subject: [PATCH 2542/6423] ALSA: hda/realtek - Apply probe-fixup really after
 probing

Move the call of alc_apply_fixup() with ALC_FIXUP_ACT_PROBE after the
whole setups of patch_ops & co, so that the fix-up function may override
the default setup.  This will be needed for installing the own unsol
event handler (e.g. for volume-knob controls).

Now adding the support for the volume-knob widget, we can move the static
quirk for ALC880 model=fujitsu to the auto-parser completely.

Subject: [PATCH 2544/6423] ASoC: imx/mxs: remove redundant SND_PCM selection

SND_PCM is already selected by SND_SOC, there is no need for
SND_IMX_SOC and SND_MXS_SOC to select it again.

Subject: [PATCH 2545/6423] ALSA: hda/realtek - Rewrite ALC880 model=F1734 with
 auto-parser

Similar as the previous patch for model=fujitsu, we can now move the
static quirk for F1734 to the auto-parser.  The only difference is the
default pin configurations: F1734 has less pins than Amilo's.

From: Takashi Iwai <tiwai@suse.de>
Date: Mon, 20 Feb 2012 17:20:48 +0100
Subject: [PATCH 2547/6423] ALSA: hda/realtek - Rewrite ALC880 model=uniwill
 with auto-parser

The model=uniwill would work almost as is, but a couple of adjustments
are needed to make the mutli-io working correctly.  The headphone and
speaker pins have to be marked properly in pin configs.

From: Takashi Iwai <tiwai@suse.de>

Subject: [PATCH 2548/6423] ALSA: hda/realtek - Rewrite ALC880
 model=uniwill-dig with auto-parser

ALC880 model=uniwill-dig requires the fix-up of bogus BIOS pin default
configurations.  Other than that, it's pretty normal.

Subject: [PATCH 2549/6423] ALSA: hda/realtek - Rewrite ALC880 model=z71v with
 auto-parser

ASUS Z71V has a totally broken BIOS setup (at least the info I got),
thus we need to override the whole pin-config table to make the
auto-parser working correctly.

ASUS W1V has a sane pin-config table set by BIOS.  The only missing piece
is the setup of GPIO1.

Subject: [PATCH 2551/6423] ALSA: hda/realtek - Drop model=asus* from ALC880

It turned out that BIOS on most of ASUS mobo's set the pin-config tables
reasonably well for the auto-parser.  We'd need GPIO setups, but should
work as is other than that.

From 67b6ec3196da235317ff1b9474f17379b78f3294 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Mon, 20 Feb 2012 18:20:42 +0100
Subject: [PATCH 2552/6423] ALSA: hda/realtek - Drop all ALC880 static quirks

Finally the all static quirks for ALC880 are converted to the
auto-parser.  Since we are never sure whether the BIOS on so many old
machines are really correct, the quirk table entries are copied as
they are, but just providing the proper pin-config values
accordingly.

Since alc880_quirks.c is removed, alc882_quirks.c has to be adjusted
slightly to be built again.  There might be some compile warnings due
to the remaining alc882 quirks, but these shall be killed sooner or
later, I don't care it much at this point.

Subject: [PATCH 2553/6423] ALSA: hda/realtek - Add model=fixup not to apply
 fix-ups

If anyone wants to debug the driver and avoid the existing fix-ups,
pass model=nofixup option.  Then the driver will skip to pick up the
fixup list.

Subject: [PATCH 2554/6423] Bluetooth: Add support for HCI monitor channel

The HCI monitor channel can be used to monitor all packets and events
from the Bluetooth subsystem. The monitor is not bound to any specific
HCI device and allows even capturing multiple devices at the same time.

Subject: [PATCH 2566/6423] bitops: Optimise get_order()

Optimise get_order() to use bit scanning instructions if such exist rather than
a loop.  Also, make it possible to use get_order() in static initialisations
too by building it on top of ilog2() in the constant parameter case.

This has been tested for i386 and x86_64 using the following userspace program,
and for FRV by making appropriate substitutions for fls() and fls64().  It will
abort if the case for get_order() deviates from the original except for the
order of 0, for which get_order() produces an undefined result.  This program
tests both dynamic and static parameters.

Subject: [PATCH 2568/6423] use FW 7.2.16

The patch integrates FW 7.2.16 HSI and implements driver
part of GRO flow.

FW 7.2.16 adds the ability to aggregate packets for GRO
(and not just LRO) and also fixes some bugs.

1. Added new aggregation mode: GRO. In this mode packets are aggregated
   such that the original packets can be reconstructed by the OS.
2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32.
3. Adding the FCoE statistics structures to the BNX2X HSI.
4. Wrong configuration of TX HW input buffer size may cause theoretical
   performance effect. Performed configuration fix.
5. FCOE - Arrival of packets beyond task IO size can lead to crash.
   Fix firmware data-in flow.
6. iSCSI - In rare cases of on-chip termination the graceful termination
   timer hangs, and the termination doesn't complete. Firmware fix to MSL
   timer tolerance.
7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles
   open at the initiator side. Firmware implementation corrected to drop
   FIN received out-of-order or with isles still open.
8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes
   from the beginning of iSCSI PDU. Firmware implementation corrected
   to support arbitrary aligned retransmissions.
9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic
   might lead to crash. Firmware fix to relevant flow.

From fe603b4d680a2bba9d8c6d4267450fcf295f30d1 Mon Sep 17 00:00:00 2001

Date: Mon, 20 Feb 2012 09:59:11 +0000
Subject: [PATCH 2571/6423] bnx2x: add gro_check

The patch provides workaround for BUG in FW 7.2.16,
which in GRO mode may miscalculate buffer and
place on SGE one frag less than it could.
It may happen only for some MTUs, we mark these MTUs
with gro_check flag during device initialization or
MTU change.

Next FW should include fix for the issue and the
patch could be reverted.

Subject: [PATCH 2573/6423] OMAPDSS: cleanup probe functions

Now that dss is using devm_ functions for allocation in probe functions,
small reordering of the allocations allows us to clean up the probe
functions more.

This patch moves "unmanaged" allocations after the managed ones, and
uses plain returns instead of gotos where possible. This lets us remove
a bunch of goto labels, simplifying the probe's error handling.

Subject: [PATCH 2574/6423] OMAPDSS: Features: Maintain dss_feats as a list

The number of dss_feat_id members has increased to a large value, the current
way of assigning a subset of these features (for a particular OMAP) as a mask
is no longer feasible.

Maintain the subset of features supported as lists. Make the function
dss_has_feature() traverse through this list.

Subject: [PATCH 2575/6423] OMAPDSS: DISPC: Fix scaling constraints for OMAP4

The calculation of required DISPC_FCLK for downscaling is done by multplying the
pixel clock with an integer factor. This isn't true for OMAP4 where the required
clock is calculated using the exact ratio of downscaling done.

Fix this calculation for OMAP4. Also, do a minor clean up of calc_fclk().

With AVI infoframe various parameters of video stream such as
aspect ratio, quantization range, videocode etc will be indicated
from source to sink.Thus AVI information needs to be set/accessed
by the middle ware based on the video content.
Thus this parameter is now moved to the ip_data structure.

Subject: [PATCH 2578/6423] OMAPDSS: TPO-TD03MTEA1: fix suspend hang

During system suspend, at the time DSS is being suspended, SPI is
already suspended and it's clocks are cut. Because of this trying to
communicate with the LCD controller results in a deadlock.

To fix this, split out LCD programming parts of display enable/disable
functions and perform them from SPI PM callbacks instead when system is
being suspended. If the display is just being enabled/disabled, do it
from DSS callbacks as before.

Subject: [PATCH 2580/6423] OMAPDSS: Add DSS feature for HDMI MCLK for audio

Certain OMAP4 revisions (i.e., 4430 ES2.3, 4460, and 4470) use
a pseudo clock (generated from the TMDS clock), MCLK, to drive the
generation of Audio Clock Regeneration packets. Other devices
(i.e., 4430 ES2.[0,2]) use the TMDS clock directly.

This patch adds a new DSS feature for MCLK support. It also rearranges
the omap_dss_features structures to reflect the devices supporting it.

Subject: [PATCH 2581/6423] OMAPDSS: HDMI: Implement initialization of MCLK

When the MCLK is used to drive the Audio Clock Regeneration packets,
the initialization procedure is to set ACR_CTRL[2] to 0 and then
back again to 1. Also, devices that do not support the MCLK, use
the TMDS clock directly by leaving ACR_CTRL[2] set to 0.

The MLCK clock divisor, mclk_mode, is configured only if MLCK
is used. Such configuration is no longer related to the CTS mode
as in some silicon revisions CTS SW-mode is used along with the MCLK.

Subject: [PATCH 2582/6423] OMAPDSS: HDMI: Modify logic to configure MCLK

The MCLK mode defines a factor to divide the clock that is used to
generate the Audio Clock Regeneration packets, MCLK.

The divisor is not used when the CTS value is calculated by HW.
When the value is calculated by SW, it depends on the silicon
revision.

the same driver though it is an ADC only part. Add the device ID to the
WM8776 driver, further updates will be added in the future.

Subject: [PATCH 2588/6423] regulator: Remove ifdefs for debugfs code

If CONFIG_DEBUG_FS=y debugfs functions will never return an
ERR_PTR. Instead they'll return NULL. The intent is to remove
ifdefs in calling code.

Update the code to reflect this. We gain an extra dentry pointer
per struct regulator and struct regulator_dev but that should be
ok because most distros have debugfs compiled in anyway.

From 164f73ee93131f67a61eaca6a6f6180580c39445 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Tue, 21 Feb 2012 11:27:09 +0100
Subject: [PATCH 2591/6423] ALSA: hda/realtek - Parse aa-loopback items
 dynamically

Similarly in patch_via.c, parse the active analog-loopback connections
and create a list dynamically rather than static arrays.

Subject: [PATCH 2623/6423] ALSA: hda/realtek - Fix possible Oops with NULL
 input_mux

When BIOS is damn crazy and gives no pin-config at all, the driver might
lead to a NULL dereference.  Let's add a NULL check for such a case.

Subject: [PATCH 2624/6423] HID: wacom: Force new name for Wacom Intuos4 WL
 PTK-540WL

The name reported by Inutos4 WL connected by bluetooth is "PTK-540WL" and
to make it consistent with other Wacom devices it has to be converted to
"Wacom Intuos4 WL". It also makes userland applications aware that it's
a Wacom device.

This aligns naming of device to same used when this device is plugged into USB
port and controlled by USB wacom driver; and thus helps align userland logic to
route to apps like xf86-input-wacom.

 for shared DAC

Even if the outputs are using shared DACs, we can still create individual
mute siwtches since they are assigned per pin.  This allows to create,
e.g. Speaker and Bass Speaker mute switches while the single volume is
used for these outputs.

When the multi-io is added to the two speaker output configuration,
the parser would try to add yet another "Bass Speaker" control since
it checks only cfg->line_outs.  Add a workaround for it by simply
passing the channel name in the case of multi-io outputs.

When the machine has two speakers but wants to put more multi-io
jacks, the parser shouldn't consider about the shared DAC but try to
assign the individual DACs.  Otherwise the channel mapping would be
fairly confused and lead to the wrong DACs.

Subject: [PATCH 2628/6423] Bluetooth: Only keep controller up after init if
 powered on

When a new controller gets added to the system, it needs to be brought
up briefly to read basic information like features, BD_ADDR etc. and
after a timeout it will be brought back down.

The only command that should overwrite this timeout is the set power
command from the management interface. Just reading the controller
list or information is not a good reason to keep the controller up.

Subject: [PATCH 2630/6423] ALSA: hda/realtek - Small code cleanups

A few clean-ups for post-static-quirk time:
- Call alc_auto_init_std() statically in alc_init() instead of setting
  spec->init_hook in each caller.  spec->init_hook field is left
  unused for any future use.

- Move the call of set_capture_mixer() to to alc_parse_auto_config()
  instead of each caller.

- Get rid of the ADC-filling and imux check in each parser function.
  This is no longer needed since the auto-parser always check ADCs and
  imux.  It was only for the static quirks.

- Kill unused defines

Subject: [PATCH 2635/6423] PCMCIA: sa11x0: h3600: convert to use new irq/gpio
 management

Convert iPAQ socket driver to use the new irq/gpio management.  As
this already uses the GPIO subsystem, these changes are localized
to just the PCMCIA directory.

Subject: [PATCH 2636/6423] PCMCIA: soc_common: remove soc_pcmcia_*_irqs
 functions

Now that we use gpios and gpio_to_irq() etc to manage the various card
status signals within soc_common, and all socket drivers are converted,
these functions are no longer used.  We can now get rid of these helper
functions.

Subject: [PATCH 2639/6423] PCMCIA: sa1111: jornada720: no need to disable IRQs
 around sa1111_set_io

sa1111_set_io() already contains the necessary locking within itself
to safely change the state of a set of GPIOs.  There's no need for
callers to protect this by disabling IRQs themselves.

Subject: [PATCH 2643/6423] HID: use generic driver for Logitech Unifying
 receivers if !CONFIG_HID_LOGITECH_DJ

Before commit 534a7b8e1 ("HID: Add full support for Logitech Unifying
receivers") Logitech Unifying receiver can work as generic device
without special driver, after that commit these devices does not works
without special driver.

After this patch they will use generic driver if special driver is disabled.

Subject: [PATCH 2644/6423] xfs: change available ranges of softlimit and
 hardlimit in quota check

In general, quota allows us to use disk blocks and inodes up to each
limit, that is, they are available if they don't exceed their limitations.
Current xfs sets their available ranges to lower than them except disk
inode quota check. So, this patch changes the ranges to not beyond them.

Subject: [PATCH 2645/6423] xfs: make inode quota check more general

The xfs checks quota when reserving disk blocks and inodes. In the block
reservation, it checks if the total number of blocks including current
usage and new reservation exceed quota. In the inode reservation,
it checks using the total number of inodes including only current usage
without new reservation. However, this inode quota check works well
since the caller of xfs_trans_dquot() always sets the argument of the
number of new inode reservation to 1 or 0 and inode is reserved one by
one in current xfs.

To make it more general, this patch changes it to the same way as the
block quota check.

Having the HCI_AUTO_OFF flag set means that from a mgmt interface
perspective we're still not powered, so all tests for HCI_UP should also
include a test for HCI_AUTO_OFF. This patch adds a convenience macro for
it.

Subject: [PATCH 2648/6423] Bluetooth: mgmt: Fix set_fast_connectable error
 return

This patch ensures that Set Fast Connectable fails apropriately if we
are not already in a connectable state (which is a pre-requisite for
fast connectable).

Subject: [PATCH 2649/6423] Bluetooth: mgmt: Fix pairable setting upon
 initialization

When mgmt is not in use the HCI_PAIRABLE flag will get implicitly set so
that pairing still works with old user space versions. However, as soon
as mgmt comes into play we should clear this flag so that it can be
properly set through the set_pairable command by user space.

Subject: [PATCH 2651/6423] ASoC: wm8994: Support external capacitors on
 MICBIAS2 with jack detection

When an external capacitor is connected to MICBIAS2 on devices with
jack detection (which is not required but may be done in some systems)
then the loading may mean that better performance is obtained when
the microphone bias is enabled normally rather than using the low power
mode. Provide platform data allowing systems to indicate if they require
this.

Subject: [PATCH 2652/6423] isdn: whitespace coding style cleanup

isdn source code uses a not-current coding style.

Update the coding style used on a per-line basis
so that git diff -w shows only elided blank lines
at EOF.

Done with emacs and some scripts and some typing.

Built x86 allyesconfig.
No detected change in objdump -d or size.

Subject: [PATCH 2653/6423] cgroup: Remove wrong comment on
 cgroup_enable_task_cg_list()

Remove the stale comment about RCU protection. Many callers
(all of them?) of cgroup_enable_task_cg_list() don't seem
to be in an RCU read side critical section. Besides, RCU is
not helpful to protect against while_each_thread().

Subject: [PATCH 2654/6423] cgroup: Walk task list under tasklist_lock in
 cgroup_enable_task_cg_list

Walking through the tasklist in cgroup_enable_task_cg_list() inside
an RCU read side critical section is not enough because:

- RCU is not (yet) safe against while_each_thread()

- If we use only RCU, a forking task that has passed cgroup_post_fork()
  without seeing use_task_css_set_links == 1 is not guaranteed to have
  its child immediately visible in the tasklist if we walk through it
  remotely with RCU. In this case it will be missing in its css_set's
  task list.

Thus we need to traverse the list (unfortunately) under the
tasklist_lock. It makes us safe against while_each_thread() and also
make sure we see all forked task that have been added to the tasklist.

As a secondary effect, reading and writing use_task_css_set_links are
now well ordered against tasklist traversing and modification. The new
layout is:

CPU 0                                      CPU 1

use_task_css_set_links = 1                write_lock(tasklist_lock)
read_lock(tasklist_lock)                  add task to tasklist
do_each_thread() {                        write_unlock(tasklist_lock)
	add thread to css set links       if (use_task_css_set_links)
} while_each_thread()                         add thread to css set links
read_unlock(tasklist_lock)

If CPU 0 traverse the list after the task has been added to the tasklist
then it is correctly added to the css set links. OTOH if CPU 0 traverse
the tasklist before the new task had the opportunity to be added to the
tasklist because it was too early in the fork process, then CPU 1
catches up and add the task to the css set links after it added the task
to the tasklist. The right value of use_task_css_set_links is guaranteed
to be visible from CPU 1 due to the LOCK/UNLOCK implicit barrier properties:
the read_unlock on CPU 0 makes the write on use_task_css_set_links happening
and the write_lock on CPU 1 make the read of use_task_css_set_links that comes
afterward to return the correct value.

This patch makes it possible to toggle the connectable & discoverable

track what the scan mode should be when the device is finally powered
on.

We should not stop iterating through the various settings if powered off
since most may still be set even then.

Subject: [PATCH 2667/6423] ASoC: core: Add SND_SOC_BYTES control for
 coefficient blocks

Allow devices to export blocks of registers to the application layer,
intended for use for reading and writing coefficient data which can't
usefully be worked with by the kernel at runtime (for example, due to
requiring complex and expensive calculations or being the results of
callibration procedures). Currently drivers are using platform data to
provide configurations for coefficient blocks which isn't at all
convenient for runtime management or configuration development.

Currently only devices using regmap are supported, an error will be
generated for any attempt to work with a byte control on a non-regmap
device. There's no fundamental block to other devices so support could
be added if required.

Subject: [PATCH 2668/6423] ASoC: core: Add support for masking out parts of
 coefficient blocks

Chip designers frequently include things like the enable and disable
controls for algorithms in the register blocks which also hold the
coefficients. Since it's desirable to split out the enable/disable
control from userspace the plain SND_SOC_BYTES() isn't optimal for
these devices.

Add a SND_SOC_BYTES_MASK() which allows a bitmask from the first word
of the block to be excluded from the control. This supports the needs
of devices I've looked at and lets us have a reasonably simple API.
Further controls can be added in future if that's needed.

Subject: [PATCH 2673/6423] datagram: Add offset argument to
 __skb_recv_datagram

This one is only considered for MSG_PEEK flag and the value pointed by
it specifies where to start peeking bytes from. If the offset happens to
point into the middle of the returned skb, the offset within this skb is
put back to this very argument.

Subject: [PATCH 2675/6423] sock: Introduce the SO_PEEK_OFF sock option

This one specifies where to start MSG_PEEK-ing queue data from. When
set to negative value means that MSG_PEEK works as ususally -- peeks
from the head of the queue always.

When some bytes are peeked from queue and the peeking offset is non
negative it is moved forward so that the next peek will return next
portion of data.

When non-peeking recvmsg occurs and the peeking offset is non negative
is is moved backward so that the next peek will still peek the proper
data (i.e. the one that would have been picked if there were no non
peeking recv in between).

The offset is set using per-proto opteration to let the protocol handle
the locking issues and to check whether the peeking offset feature is
supported by the protocol the socket belongs to.

Subject: [PATCH 2676/6423] unix: Support peeking offset for datagram and
 seqpacket sockets

The sk_peek_off manipulations are protected with the unix_sk->readlock mutex.
This mutex is enough since all we need is to syncronize setting the offset
vs reading the queue head. The latter is fully covered with the mentioned lock.

The recently added __skb_recv_datagram's offset is used to pick the skb to
read the data from.

Subject: [PATCH 2677/6423] unix: Support peeking offset for stream sockets

The same here -- we can protect the sk_peek_off manipulations with
the unix_sk->readlock mutex.

The peeking of data from a stream socket is done in the datagram style,
i.e. even if there's enough room for more data in the user buffer, only
the head skb's data is copied in there. This feature is preserved when
peeking data from a given offset -- the data is read till the nearest
skb's boundary.

Subject: [PATCH 2678/6423] of: Only compile OF_DYNAMIC on PowerPC pseries and
 iseries

Only two architectures use the OF node reference counting and reclaim bits.
There is no need to compile it for the rest of the PowerPC platforms or for
any of the other architectures.  This patch makes iseries and pseries
select CONFIG_OF_DYNAMIC, and makes it default to off for everything else.

It is still safe to turn on CONFIG_OF_DYNAMIC on all architectures, it just
isn't necessary.

v2: Also select OF_DYNAMIC for PPC_CHROMA and MPC885ADS as reported by Michael
    Meuling

Subject: [PATCH 2679/6423] i387: Uninline the generic FP helpers that we
 expose to kernel modules

Instead of exporting the very low-level internals of the FPU state
save/restore code (ie things like 'fpu_owner_task'), we should export
the higher-level interfaces.

Inlining these things is pointless anyway: sure, sometimes the end
result is small, but while 'stts()' can result in just three x86
instructions, those are not cheap instructions (writing %cr0 is a
serializing instruction and a very slow one at that).

So the overhead of a function call is not noticeable, and we really
don't want random modules mucking about with our internal state save
logic anyway.

So this unexports 'fpu_owner_task', and instead uninlines and exports
the actual functions that modules can use: fpu_kernel_begin/end() and
unlazy_fpu().

From 1361b83a13d4d92e53fbb6c877528713e118b821 Mon Sep 17 00:00:00 2001
From: Linus Torvalds <torvalds@linux-foundation.org>
Date: Tue, 21 Feb 2012 13:19:22 -0800
Subject: [PATCH 2680/6423] i387: Split up <asm/i387.h> into exported and
 internal interfaces

While various modules include <asm/i387.h> to get access to things we
actually *intend* for them to use, most of that header file was really
pretty low-level internal stuff that we really don't want to expose to
others.

So split the header file into two: the small exported interfaces remain
in <asm/i387.h>, while the internal definitions that are only used by
core architecture code are now in <asm/fpu-internal.h>.

The guiding principle for this was to expose functions that we export to
modules, and leave them in <asm/i387.h>, while stuff that is used by
task switching or was marked GPL-only is in <asm/fpu-internal.h>.

The fpu-internal.h file could be further split up too, especially since
arch/x86/kvm/ uses some of the remaining stuff for its module.  But that
kvm usage should probably be abstracted out a bit, and at least now the
internal FPU accessor functions are much more contained.  Even if it
isn't perhaps as contained as it _could_ be.

Subject: [PATCH 2681/6423] ARM: make arch_ret_to_user macro optional

Only 3 platforms need arch_ret_to_user macro, so add ARCH_HAS_RET_TO_USER
kconfig option and make iop13xx, iop32x and iop33x select it.

Subject: [PATCH 2682/6423] ARM: rpc: make default fiq handler run-time
 installed

Only rpc uses disable_fiq macro. Change it to a run-time installed
default FIQ handler. The handler is installed before FIQ is enabled
so the behavior should be unchanged.

With the removal of disable_fiq on rpc and addition MULTI_IRQ_HANDLER,
entry-macro.S is no longer needed for platforms that select
MULTI_IRQ_HANDLER and the include of it can be conditional.

Subject: [PATCH 2687/6423] cpufreq: OMAP: scale voltage along with frequency

Use the regulator framework to get the voltage regulator associated
with the MPU voltage domain and use it to scale voltage along with
frequency.

While here, CONFIG_CPU_FREQ_DEBUG doesn't exist anymore, so move
debug prints to use dev_dbg().

Special thanks to Afzal Mohammed for suggestions on more robust error
checking.

From 8dc50ec7755650859a7bfc17de8846ef1efa24a4 Mon Sep 17 00:00:00 2001
From: Tomi Valkeinen <tomi.valkeinen@ti.com>

Subject: [PATCH 2690/6423] OMAPFB: Remove OMAP2/3 support from old omapfb
 driver

Old omapfb driver (drivers/video/omap/) is no longer used for OMAP2+
devices, and thus we can remove OMAP2+ support from it and make it an
OMAP1 omapfb driver.

Subject: [PATCH 2691/6423] HID: add new driver for non-compliant Saitek
 devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The driver currently only supports the PS1000 controller.
It fixes the report descriptor by removing a non-existing axis and
clearing the constant bit on the d-pad and button input reports.

Subject: [PATCH 2692/6423] ALSA: hda/via - Don't create duplicated boost
 controls

The driver may create duplicated mic boost controls when there are
multiple mics with the very same type / location, and this leads to
the error at actual kcontrol creation.  It needs to check the validity
of the created control and add a proper index if it's duplicated.

Subject: [PATCH 2693/6423] ALSA: hda/via - Add a few sanity checks

Added sanity checks in a few places not to assume the pins having the
certain amp caps or the input-source being always assigned to a mux.

No actual bugs have been triggered by these, but surely better to be a
bit more robust.

Subject: [PATCH 2694/6423] regmap: Add support for writing to regmap registers
 via debugfs

To enable writing to the regmap debugfs registers file users will
need to modify the source directly and #define REGMAP_ALLOW_WRITE_DEBUGFS.
The reason for this is that it is dangerous to expose this
functionality in general where clients could potentially be PMICs.

Subject: [PATCH 2697/6423] ASoC: mxs-pcm: Request DMA channel early

Request the DMA channel in the PCM open callback instead of the hwparams
callback, this allows us to let open fail if no dma channel is available. This
also fixes a bug where the channel will be requested multiple times if hwparams
is called multiple times.

Subject: [PATCH 2700/6423] mfd/ASoC: Convert WM8994 driver to use regmap
 patches

Early revisions of several of the WM8994 variants have register updates
to improve performance. Move these over to using the regmap patch system
instead of open coding them in the audio driver. Since the regmap init
is done by the MFD the code is moved there.

new interface and rename some variables to make the semantics
understandable.

Commit 77a5988 "pinctrl: changes hog mechanism to be self-referential"
modified the way "hog" entries were represented in the mapping table.
However, the new representation failed some error checks in
pinctrl_hog_map(). Remove the now-bogus error-check, and fix the code
to solve the issue the error-check used to avoid.

Subject: [PATCH 2714/6423] pinctrl: Store mapping table as a list of chunks

Instead of storing a single array of mapping table entries, which
requires realloc()ing that array each time it's extended and copying
the new data, simply store a list of pointers to the individual chunks.
This also removes the need to copy the mapping table at all; a pointer
is maintained to the original table, this saving memory.

A macro for_each_maps() is introduced to hide the additional complexity
of iterating over the map entries.

This change will also simplify removing chunks of entries from the mapping
table. This isn't important right now, but will be in the future, when
mapping table entries are dynamically added when parsing them from the
device tree, and removed when drivers no longer need to interact with
pinctrl.

Subject: [PATCH 2718/6423] pinctrl: spawn U300 pinctrl from the COH901 GPIO

This solves the riddle on how the U300 pin controller shall be
able to reference the struct gpio_chip even though these are
two separate drivers: spawn the pinctrl child from the GPIO
driver and pass in the struct gpio_chip as platform data.
In the process we rename the U300 "pinmux-u300" to
"pinctrl-u300" so as not to confuse.

Subject: [PATCH 2720/6423] pinctrl: downgrade pinctrl_get warning when no maps
 are found

This may be perfectly legitimate. An IP block may get re-used
across SoCs. Not all of those SoCs may need pinmux settings for the
IP block, e.g. if one SoC dedicates pins to that function but
another doesn't. The driver won't know this, and will always
attempt to set up the pinmux. The mapping table defines whether any
HW programming is actually needed.

Subject: [PATCH 2722/6423] pinctrl: record a pin owner, not mux function, when
 requesting pins

When pins are requested/acquired/got, some device becomes the owner of
their mux setting. At this point, it isn't certain which mux function
will be selected for the pin, since this may vary between each of the
device's states in the pinctrl mapping table. As such, we should record
the owning device, not what we think the initial mux setting will be,
when requesting pins.

This doesn't make a lot of difference right now since pinctrl_get gets
only one single device/state combination, but this will make a difference
when pinctrl_get gets all states, and pinctrl_select_state can switch
between states.

Subject: [PATCH 2725/6423] x86: Remove some noise from boot log when starting
 cpus

Printing the "start_ip" for every secondary cpu is very noisy on a large
system - and doesn't add any value. Drop this message.

Console log before:
Booting Node   0, Processors  #1
smpboot cpu 1: start_ip = 96000
 #2
smpboot cpu 2: start_ip = 96000
 #3
smpboot cpu 3: start_ip = 96000
 #4
smpboot cpu 4: start_ip = 96000
       ...
 #31
smpboot cpu 31: start_ip = 96000
Brought up 32 CPUs

Console log after:
Booting Node   0, Processors  #1 #2 #3 #4 #5 #6 #7 Ok.
Booting Node   1, Processors  #8 #9 #10 #11 #12 #13 #14 #15 Ok.
Booting Node   0, Processors  #16 #17 #18 #19 #20 #21 #22 #23 Ok.
Booting Node   1, Processors  #24 #25 #26 #27 #28 #29 #30 #31

Subject: [PATCH 2730/6423] af_unix: MSG_TRUNC support for dgram sockets

Piergiorgio Beruto expressed the need to fetch size of first datagram in
queue for AF_UNIX sockets and suggested a patch against SIOCINQ ioctl.

I suggested instead to implement MSG_TRUNC support as a recv() input
flag, as already done for RAW, UDP & NETLINK sockets.

len = recv(fd, &byte, 1, MSG_PEEK | MSG_TRUNC);

MSG_TRUNC asks recv() to return the real length of the packet, even when
is was longer than the passed buffer.

There is risk that a userland application used MSG_TRUNC by accident
(since it had no effect on af_unix sockets) and this might break after
this patch.

Subject: [PATCH 2737/6423] brcm80211: smac: fix unintended fallthru in
 wlc_phy_radio_init_2057()

The radio initialization for 2057 rev 5 was using the incorrect
register table for the initialization. This patch fixes that.

Subject: [PATCH 2738/6423] brcm80211: smac: remove redundant assignments from
 txpwrctrl_pwr_setup_nphy

The function wlc_phy_txpwrctrl_pwr_setup_nphy() does assign a local
variable target_pwr_qtrdbm in several code paths, but in the end all
code paths are coming to an assignment of that variable which does
override all previous. So those early and redundant assignments have
been removed.

Subject: [PATCH 2739/6423] brcm80211: smac: fix endless retry of A-MPDU
 transmissions

The A-MPDU code checked against a retry limit, but it was using
the wrong variable to do so. This patch fixes this to assure
proper retry mechanism.

This problem had a side-effect causing the mac80211 flush callback
to remain waiting forever as well. That side effect has been fixed
by commit by Stanislaw Gruszka:

Subject: [PATCH 2743/6423] brcm80211: fmac: use specific types in struct
 brcmf_bus

The fields bus_priv and drvr are defined as void pointer. It is
preferred to have specific types for compiler type checking. To
prepare for other bus types the bus_priv field is defined as a
union containing the sdio bus private structure reference.

Subject: [PATCH 2745/6423] brcm80211: fmac: only return success in

The function brcmf_sdbrcm_bus_init() always returned success except for
firmware download failure. However, also when enabling SDIO function 2
is failing the function should return failure. This patch fixes that.

Subject: [PATCH 2746/6423] brcm80211: fmac: update bus state in common driver
 part

The bus state is updated in the sdio bus init function, but it is
better to do it when the brcmf_bus_start() function is completed
successfully. The brcmf_netdev_open() function will return -EAGAIN
until the state is updated instead of calling brcmf_bus_start() to
avoid reentering that function.

does enable interrupts which is not desired in the irq context. This patch
replaces them using the spin_loc_irqsave and spin_unlock_irqrestore
functions.

From 71bb244ba2fd5390eefe4ee9054abdb3f8b05922 Mon Sep 17 00:00:00 2001
From: Arend van Spriel <arend@broadcom.com>
Date: Thu, 9 Feb 2012 21:09:08 +0100
Subject: [PATCH 2749/6423] brcm80211: fmac: add USB support for bcm43235/6/8
 chipsets

This patch extends the use of the brcmfmac driver with support for
chipsets with a USB host interface. The first chipsets supported are
the bcm43235, bcm43236, and bcm43238 for which firmware has been
submitted.

This driver change has been successfully built for x86, x86_64,
ppc64, arm_le, and mips_be.

It has been tested successfully on x86 and x86_64.

Subject: [PATCH 2750/6423] brcm80211: fmac: make sdio firmware filename
 specific

The sdio driver part uses firmware name brcmfmac.bin. With addition
of usb this name is too generic. This patch renames the filename
to brcmfmac-sdio.bin.

Subject: [PATCH 2751/6423] rtlwifi: rtl8192se firmware load can overflow
 target buffer

Define RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE which represents the
maximimum possible firmware file size. Use it in the definition
of the buffer which receives the firmware file data.

Set RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE closer to the actual size of
the firmware file, e.g., 90000 (down from hard coded 164000). The current
size of rtlwifi/rtl8192sefw.bin is 88856.

Set max_fw_size to RTL8190_MAX_RAW_FIRMWARE_CODE_SIZE for the size limit
check. Fix the error case where max_fw_size is not cleared if the size
limit check fails.

 the device

Print dump stack when the device is not responding. This should give
some more clue about the reason of failure. Also change the message we
print, since "MAC in deep sleep" is kinda confusing.

On the way add unlikely(), as fail to gain NIC access is hmm ...
unlikely.

Change type return type _il_grap_nic_access() to bool, and

Subject: [PATCH 2754/6423] iwlegacy: cleanup/fix memory barriers

wmb(), rmb() are not needed when writel(), readl() are used as
accessors for MMIO. We use them indirectly via iowrite32(),
ioread32().

What is needed mmiowb(), for synchronizing writes coming from
different CPUs on PCIe bridge (see in patch comments). This
fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlegacy devices are most likely
not used on anything other than x86, this is not so important
fix.

If rfkill is on il_grab_nic_access() fail and we can not write to the
various registers during stop procedure. Write to those registers
unconditionally instead.

Subject: [PATCH 2776/6423] cfg80211: restructure AP/GO mode API

The AP/GO mode API isn't very clearly defined, it
has "set beacon" and "new beacon" etc.

Modify the API to the following:
 * start AP -- all settings
 * change beacon -- new beacon data
 * stop AP -- stop AP mode operation

This also reflects in the nl80211 API, rename
the commands there correspondingly (but keep
the old names for compatibility.)

Overall, this makes it much clearer what's going
on in the API.

Kalle developed the ath6kl changes, I created
the rest of the patch.

Subject: [PATCH 2777/6423] ath5k:Remove __raw_read and __raw_write

By swithing from our __raw_read and __raw_write functions to ioread32 and iowrite32,
benchmarks on my desk with iperf went from 11MBps to 18.1MBps using the AHB bus
on an EnGenius ECB3500 running OpenWRT.

Subject: [PATCH 2780/6423] sfc: Specify that the VFDI status page has page
 alignment and size

This requirement was meant to be implied in the name 'status page'.
One out-of-tree VF driver allocates a buffer using the structure size
and not a full page - hence the current odd specification - but in
practice that allocation will be padded and aligned to at least 4KB.
Therefore, we can specify this and have the option to extend the
structure up to 4KB without worrying about VF drivers using odd-shaped
buffers.

Subject: [PATCH 2781/6423] sfc: Correct validation of peer_page_count in
 efx_vfdi_set_status_page()

efx_vfdi_set_status_page() validates the peer page count by
calculating the size of a request containing that many addresses and
comparing that with the maximum valid request size (4KB).  The
calculation involves a multiplication that may overflow on a 32-bit
system.

We use kcalloc() to allocate memory to store the addresses; that also
does a multiplication and it does check for integer overflow, so any
values larger than 0x1fffffff will be rejected.  However, values in
the range [0x1fffffffc, 0x1fffffff] pass boh tests and result in an
attempt to allocate nearly 4GB on the heap.  This should be rejected
rather quickly as it's obviously impossible on a 32-bit system, and
indeed the maximum possible heap allocation is 32MB.  Still, let's
make absolutely sure by fixing the initial validation.

Subject: [PATCH 2782/6423] sfc: Reverse initial buffer table allocation to
 allow for later resizing

We have a very simple way of allocating buffer table entries to
queues, which is just to take the next one available.  The extra
channels are the highest numbered channels but they need to be
allocated the lowest entries so that the traffic channels can be
allocated new entries without any collisions.

Subject: [PATCH 2784/6423] x86/mce: Convert static array of pointers to
 per-cpu variables

When I previously fixed up the mce_device code, I used a static array of
the pointers.  It was (rightfully) pointed out to me that I should be
using the per_cpu code instead.

This patch converts the code over to that structure, moving the variable
back into the per_cpu area, like it used to be for 3.2 and earlier.

Current kernel MCE code reads ERST at the first reading of /dev/mcelog
(maybe in starting mcelogd,) even if the system does not support ERST,
which results in a fake "no such device" message (as described in [1].)
This problem is not critical, but can confuse system admins.
This patch fixes it by filtering the return value from lower (ACPI) layer.

Subject: [PATCH 2786/6423] firewire: sbp2: identify to driver core as
 "firewire_sbp2", not "sbp2"

Commit eba9ebaaa26d "firewire: sbp2: use dev_printk API" changed
messages from e.g.
    firewire_sbp2: fw3.0: logged in to LUN 0000 (0 retries)
to
    sbp2 fw3.0: logged in to LUN 0000 (0 retries)
because the driver calls itself as "sbp2" when registering with driver
core and with SCSI core.  This is of course confusing, so switch to the
name "firewire_sbp2" for driver core in order to match what lsmod and
/sys/module/ show.  So we are back to
    firewire_sbp2 fw3.0: logged in to LUN 0000 (0 retries)
in the kernel log.

This also changes
    /sys/bus/firewire/drivers/sbp2
    /sys/bus/firewire/devices/fw3.0/driver -> [...]/sbp2
    /sys/module/firewire_sbp2/drivers/firewire:sbp2
to
    /sys/bus/firewire/drivers/firewire_sbp2
    /sys/bus/firewire/devices/fw3.0/driver -> [...]/firewire_sbp2
    /sys/module/firewire_sbp2/drivers/firewire:firewire_sbp2

but "cat /sys/class/scsi_host/host27/proc_name" stays "sbp2" just in
case that proc_name is used by any userland.

The transport detection in lsscsi is not affected.  (Tested with lsscsi
version 0.25.)  Udev's /dev/disk/by-id and by-path symlinks are not
affected either.

Subject: [PATCH 2787/6423] firewire: net: identify to driver core as
 "firewire_net", not "net"

On second thought, there is little reason to have driver name differ
from module name.  Therefore, change
    /sys/bus/firewire/drivers/net
    /sys/bus/firewire/devices/fw0.0/driver -> [...]/net
    /sys/module/firewire_net/drivers/firewire:net
to
    /sys/bus/firewire/drivers/firewire_net
    /sys/bus/firewire/devices/fw0.0/driver -> [...]/firewire_net
    /sys/module/firewire_net/drivers/firewire:firewire_net
It is redundant but consistent with firewire-sbp2's recently changed
driver name.

I don't see this anywhere used, so it should not matter either way.

Subject: [PATCH 2788/6423] firewire: net: use dev_printk API

Change the log line prefix from "firewire_net: " to "net firewire0: "
etc. for the case that several RFC 2734 interfaces are being used in the
same machine.

Note, the netdev_printk API is not very useful to firewire-net.
netdev_notice(net, "abc\n") would result in irritating messages like
"firewire_ohci 0000:0a:00.0: firewire0: abc".  Nor would a dev_printk on
the fw_unit.device to which firewire-net is being bound be useful,
because there are generally multiple ones of those per interface (from
all RFC 2734 peers on the bus, the local node being only one of them).

In the initialization message of each interface, log the PCI device
name of the card which is parent of the netdevice instead of the GUID
of the peer which was semi-randomly used to establish the netdevice.

Subject: [PATCH 2789/6423] firewire: core: prefix log messages with card name

Associate all log messages from firewire-core with the respective card
because some people have more than one card.  E.g.
    firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0
    firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0
    firewire_core: created device fw0: GUID 0814438400000389, S800
    firewire_core: phy config: new root=ffc1, gap_count=5
    firewire_core: created device fw1: GUID 0814438400000388, S800
    firewire_core: created device fw2: GUID 0001d202e06800d1, S800
turns into
    firewire_ohci 0000:04:00.0: added OHCI v1.10 device as card 0, 8 IR + 8 IT contexts, quirks 0x0
    firewire_ohci 0000:05:00.0: added OHCI v1.10 device as card 1, 8 IR + 8 IT contexts, quirks 0x0
    firewire_core 0000:04:00.0: created device fw0: GUID 0814438400000389, S800
    firewire_core 0000:04:00.0: phy config: new root=ffc1, gap_count=5
    firewire_core 0000:05:00.0: created device fw1: GUID 0814438400000388, S800
    firewire_core 0000:04:00.0: created device fw2: GUID 0001d202e06800d1, S800

This increases the module size slightly; to keep this in check, turn the
former printk wrapper macros into functions.  Their implementation is
largely copied from driver core's dev_printk counterparts.

Subject: [PATCH 2790/6423] firewire: core: remove obsolete comment

Target-like applications or peer-to-peer-like applications require the
global address handler registration which we have right now, or a per-
card registration.  And node lookup, while it would be nice to have,
would be impossible in the brief time between self-ID-complete event and
completion of firewire-core's topology scanning.

Subject: [PATCH 2791/6423] firewire: core: fix race at address_handler
 unregistration

Fix the following unlikely but possible race:

CPU 1                             CPU 2
------------------------------------------------------------------------
AR-request tasklet
    lookup handler
                                  unregister handler
				  free handler->callback_data or handler
    call handler->callback

The application which registered the handler has no way to stop nodes
sending new requests to their address range, hence cannot prevent this
race.

Fix it simply by extending the address_handler_lock-protected region
from only around the lookup to around both lookup and call.  We only
need to do so in the exclusive region handler; the FCP region handler
already holds the lock around the handler->callback call.

Alas this removes the current ability to execute the callback in
parallel on different CPUs if it was called for different FireWire cards
at the same time.  (For a single card, the handler is already
serialized.)  If this loss of a rather obscure feature is not tolerable,
a more complex fix would be required:  Add a handler reference counter;
wait in fw_core_remove_address_handler() for this conter to become zero.

Subject: [PATCH 2792/6423] firewire: core: convert AR-req handler lock from
 _irqsave to _bh

fw_core_handle_request() is called by the low-level driver in tasklet
context or process context, and fw_core_add/remove_address_handler() is
called by mid- or high-level code in process context.  So convert
address_handler_lock accesses from those which disable local IRQs to
ones which just disable local softIRQs.

If the target's unit directory contains a Unit_Unique_ID entry, we
should use that as the target's GUID for identification purposes. The
SBP-2 standards document says:

"Although the node unique ID (EUI-64) present in the bus information
block is sufficient to uniquely identify nodes attached to Serial Bus,
it is insufficient to identify a target when a vendor implements a
device with multiple Serial Bus node connections. In this case initiator
software requires information by which a particular target may be
uniquely identified, regardless of the Serial Bus access path used."

The firewire-sbp2 module tries to login to an SBP-2/3 target even when
it is running on the local node, which fails because of the inability to
fetch data from DMA mapped regions using firewire transactions on the
local node. It also doesn't make much sense to have the initiator and
target on the same node, so this patch prevents this behaviour.

Subject: [PATCH 2796/6423] firewire: sbp2: Fix SCSI sense data mangling

SCSI sense data in SBP-2/3 is carried in an unusual format that means we
have to un-mangle it on our end before we pass it to the SCSI subsystem.
Currently our un-mangling code doesn't quite follow the SBP-2 standard
in that we always assume Current and never Deferred error types, we
never set the VALID bit, and we mishandle the FILEMARK, EOM and ILI
bits.

This patch fixes the sense un-mangling to correctly handle those and
follow the spec.

"mpic->flags" variable (EG: "big-endian" => MPIC_BIG_ENDIAN).

Unfortunately, a number of codepaths (including several which test the
flag MPIC_BIG_ENDIAN!) test "flags" instead of "mpic->flags", and get
wrong answers as a result.

Consolidate the device-tree flag tests early in mpic_alloc() and change
all of the checks after "mpic->flags" is init'ed to use "mpic->flags".

[BenH: Fixed up use of mpic->node before it's initialized]

Subject: [PATCH 2798/6423] fsl/mpic: Document and use the "big-endian"
 device-tree flag

The MPIC code checks for a "big-endian" property and sets the flag
MPIC_BIG_ENDIAN if one is present, although prior to the "mpic->flags"
fixup that would never have worked anways.

Unfortunately, even now that it works properly, the Freescale mpic
device-node (the "PowerQUICC-III"-compatible one) does not specify it,
so all of the board ports need to manually pass it to mpic_alloc().

Document the flag and add it to the pq3 device tree.  Existing code will
still need to pass the MPIC_BIG_ENDIAN flag because their dtb may not
have this property, but new platforms shouldn't need to do so.

Subject: [PATCH 2799/6423] fsl/mpic: Create and document the
 "single-cpu-affinity" device-tree flag

The Freescale MPIC (and perhaps others in the future) is incapable of
routing non-IPI interrupts to more than once CPU at a time.  Currently
all of the Freescale boards msut pass the MPIC_SINGLE_DEST_CPU flag to
mpic_alloc(), but that information should really be present in the
device-tree.

Older board code can't rely on the device-tree having the property set,
but newer platforms won't need it manually specified in the code.

Subject: [PATCH 2800/6423] powerpc/mpic: Remove MPIC_BROKEN_FRR_NIRQS and
 duplicate irq_count

The mpic->irq_count variable is only used as a software error-checking
limit to determine whether or not an IRQ number is valid.  In board code
which does not manually specify an IRQ count to mpic_alloc(), i.e. 0, it
is automatically detected from the number of ISUs and the ISU size.

In practice, all hardware ends up with irq_count == num_sources, so all
of the runtime checks on mpic->irq_count should just check the value of
mpic->num_sources instead.

When platform hardware does not correctly report the number of IRQs,
which only happens on the MPC85xx/MPC86xx, the MPIC_BROKEN_FRR_NIRQS
flag is used to override the detected value of num_sources with the
manual irq_count parameter.  Since there's no need to manually specify
the number of IRQs except in this case, the extra flag can be eliminated
and the test changed to "irq_count != 0".

Subject: [PATCH 2801/6423] powerpc/mpic: Add "last-interrupt-source" property
 to override hardware

The FreeScale PowerQUICC-III-compatible (mpc85xx/mpc86xx) MPICs do not
correctly report the number of hardware interrupt sources, so software
needs to override the detected value with "256".

To avoid needing to write custom board-specific code to detect that
scenario, allow it to be easily overridden in the device-tree.

Subject: [PATCH 2802/6423] powerpc/mpic: Remove duplicate MPIC_WANTS_RESET
 flag

There are two separate flags controlling whether or not the MPIC is
reset during initialization, which is completely unnecessary, and only
one of them can be specified in the device tree.

Also, most platforms in-tree right now do actually want to reset the
MPIC during initialization anyways, which means lots of duplicate code
passing the MPIC_WANTS_RESET flag.

Fix all of the callers which currently do not pass the MPIC_WANTS_RESET
flag to pass the MPIC_NO_RESET flag, then remove the MPIC_WANTS_RESET
flag and make the code reset the MPIC by default.

+                   Firmware-Assisted Dump
+                   ------------------------
+                       July 2011
+
+The goal of firmware-assisted dump is to enable the dump of
+a crashed system, and to do so from a fully-reset system, and
+to minimize the total elapsed time until the system is back
+in production use.
+
+- Firmware assisted dump (fadump) infrastructure is intended to replace
+  the existing phyp assisted dump.
+- Fadump uses the same firmware interfaces and memory reservation model
+  as phyp assisted dump.
+- Unlike phyp dump, fadump exports the memory dump through /proc/vmcore
+  in the ELF format in the same way as kdump. This helps us reuse the
+  kdump infrastructure for dump capture and filtering.
+- Unlike phyp dump, userspace tool does not need to refer any sysfs
+  interface while reading /proc/vmcore.
+- Unlike phyp dump, fadump allows user to release all the memory reserved
+  for dump, with a single operation of echo 1 > /sys/kernel/fadump_release_mem.
+- Once enabled through kernel boot parameter, fadump can be
+  started/stopped through /sys/kernel/fadump_registered interface (see
+  sysfs files section below) and can be easily integrated with kdump
+  service start/stop init scripts.
+
+Comparing with kdump or other strategies, firmware-assisted
+dump offers several strong, practical advantages:
+
+-- Unlike kdump, the system has been reset, and loaded
+   with a fresh copy of the kernel.  In particular,
+   PCI and I/O devices have been reinitialized and are
+   in a clean, consistent state.
+-- Once the dump is copied out, the memory that held the dump
+   is immediately available to the running kernel. And therefore,
+   unlike kdump, fadump doesn't need a 2nd reboot to get back
+   the system to the production configuration.
+
+The above can only be accomplished by coordination with,
+and assistance from the Power firmware. The procedure is
+as follows:
+
+-- The first kernel registers the sections of memory with the
+   Power firmware for dump preservation during OS initialization.
+   These registered sections of memory are reserved by the first
+   kernel during early boot.
+
+-- When a system crashes, the Power firmware will save
+   the low memory (boot memory of size larger of 5% of system RAM
+   or 256MB) of RAM to the previous registered region. It will
+   also save system registers, and hardware PTE's.
+
+   NOTE: The term 'boot memory' means size of the low memory chunk
+         that is required for a kernel to boot successfully when
+         booted with restricted memory. By default, the boot memory
+         size will be the larger of 5% of system RAM or 256MB.
+         Alternatively, user can also specify boot memory size
+         through boot parameter 'fadump_reserve_mem=' which will
+         override the default calculated size. Use this option
+         if default boot memory size is not sufficient for second
+         kernel to boot successfully.
+
+-- After the low memory (boot memory) area has been saved, the
+   firmware will reset PCI and other hardware state.  It will
+   *not* clear the RAM. It will then launch the bootloader, as
+   normal.
+
+-- The freshly booted kernel will notice that there is a new
+   node (ibm,dump-kernel) in the device tree, indicating that
+   there is crash data available from a previous boot. During
+   the early boot OS will reserve rest of the memory above
+   boot memory size effectively booting with restricted memory
+   size. This will make sure that the second kernel will not
+   touch any of the dump memory area.
+
+-- User-space tools will read /proc/vmcore to obtain the contents
+   of memory, which holds the previous crashed kernel dump in ELF
+   format. The userspace tools may copy this info to disk, or
+   network, nas, san, iscsi, etc. as desired.
+
+-- Once the userspace tool is done saving dump, it will echo
+   '1' to /sys/kernel/fadump_release_mem to release the reserved
+   memory back to general use, except the memory required for
+   next firmware-assisted dump registration.
+
+   e.g.
+     # echo 1 > /sys/kernel/fadump_release_mem
+
+Please note that the firmware-assisted dump feature
+is only available on Power6 and above systems with recent
+firmware versions.
+
+Implementation details:
+----------------------
+
+During boot, a check is made to see if firmware supports
+this feature on that particular machine. If it does, then
+we check to see if an active dump is waiting for us. If yes
+then everything but boot memory size of RAM is reserved during
+early boot (See Fig. 2). This area is released once we finish
+collecting the dump from user land scripts (e.g. kdump scripts)
+that are run. If there is dump data, then the
+/sys/kernel/fadump_release_mem file is created, and the reserved
+memory is held.
+
+If there is no waiting dump data, then only the memory required
+to hold CPU state, HPTE region, boot memory dump and elfcore
+header, is reserved at the top of memory (see Fig. 1). This area
+is *not* released: this region will be kept permanently reserved,
+so that it can act as a receptacle for a copy of the boot memory
+content in addition to CPU state and HPTE region, in the case a
+crash does occur.

+   kernel to boot
+                   Fig. 2
+
+Currently the dump will be copied from /proc/vmcore to a
+a new file upon user intervention. The dump data available through
+/proc/vmcore will be in ELF format. Hence the existing kdump
+infrastructure (kdump scripts) to save the dump works fine with
+minor modifications.
+
+The tools to examine the dump will be same as the ones
+used for kdump.
+
+How to enable firmware-assisted dump (fadump):
+-------------------------------------
+
+1. Set config option CONFIG_FA_DUMP=y and build kernel.
+2. Boot into linux kernel with 'fadump=on' kernel cmdline option.
+3. Optionally, user can also set 'fadump_reserve_mem=' kernel cmdline
+   to specify size of the memory to reserve for boot memory dump
+   preservation.
+
+NOTE: If firmware-assisted dump fails to reserve memory then it will
+   fallback to existing kdump mechanism if 'crashkernel=' option
+   is set at kernel cmdline.
+
+Sysfs/debugfs files:
+------------
+
+Firmware-assisted dump feature uses sysfs file system to hold
+the control files and debugfs file to display memory reserved region.
+
+Here is the list of files under kernel sysfs:
+
+ /sys/kernel/fadump_enabled
+
+    This is used to display the fadump status.
+    0 = fadump is disabled
+    1 = fadump is enabled
+
+    This interface can be used by kdump init scripts to identify if
+    fadump is enabled in the kernel and act accordingly.
+
+ /sys/kernel/fadump_registered
+
+    This is used to display the fadump registration status as well
+    as to control (start/stop) the fadump registration.
+    0 = fadump is not registered.
+    1 = fadump is registered and ready to handle system crash.
+
+    To register fadump echo 1 > /sys/kernel/fadump_registered and
+    echo 0 > /sys/kernel/fadump_registered for un-register and stop the
+    fadump. Once the fadump is un-registered, the system crash will not
+    be handled and vmcore will not be captured. This interface can be
+    easily integrated with kdump service start/stop.
+
+ /sys/kernel/fadump_release_mem
+
+    This file is available only when fadump is active during
+    second kernel. This is used to release the reserved memory
+    region that are held for saving crash dump. To release the
+    reserved memory echo 1 to it:
+
+    echo 1  > /sys/kernel/fadump_release_mem
+
+    After echo 1, the content of the /sys/kernel/debug/powerpc/fadump_region
+    file will change to reflect the new memory reservations.
+
+    The existing userspace tools (kdump infrastructure) can be easily
+    enhanced to use this interface to release the memory reserved for
+    dump and continue without 2nd reboot.
+
+Here is the list of files under powerpc debugfs:
+(Assuming debugfs is mounted on /sys/kernel/debug directory.)
+
+ /sys/kernel/debug/powerpc/fadump_region
+
+    This file shows the reserved memory regions if fadump is
+    enabled otherwise this file is empty. The output format
+    is:
+    <region>: [<start>-<end>] <reserved-size> bytes, Dumped: <dump-size>
+
+    e.g.
+    Contents when fadump is registered during first kernel
+
+    # cat /sys/kernel/debug/powerpc/fadump_region
+    CPU : [0x0000006ffb0000-0x0000006fff001f] 0x40020 bytes, Dumped: 0x0
+    HPTE: [0x0000006fff0020-0x0000006fff101f] 0x1000 bytes, Dumped: 0x0
+    DUMP: [0x0000006fff1020-0x0000007fff101f] 0x10000000 bytes, Dumped: 0x0
+
+    Contents when fadump is active during second kernel
+
+    # cat /sys/kernel/debug/powerpc/fadump_region
+    CPU : [0x0000006ffb0000-0x0000006fff001f] 0x40020 bytes, Dumped: 0x40020
+    HPTE: [0x0000006fff0020-0x0000006fff101f] 0x1000 bytes, Dumped: 0x1000
+    DUMP: [0x0000006fff1020-0x0000007fff101f] 0x10000000 bytes, Dumped: 0x10000000
+        : [0x00000010000000-0x0000006ffaffff] 0x5ffb0000 bytes, Dumped: 0x5ffb0000
+
+NOTE: Please refer to Documentation/filesystems/debugfs.txt on
+      how to mount the debugfs filesystem.
+
+
+TODO:
+-----
+ o Need to come up with the better approach to find out more
+   accurate boot memory size that is required for a kernel to
+   boot successfully when booted with restricted memory.
+ o The fadump implementation introduces a fadump crash info structure
+   in the scratch area before the ELF core header. The idea of introducing
+   this structure is to pass some important crash info data to the second
+   kernel which will help second kernel to populate ELF core header with
+   correct data before it gets exported through /proc/vmcore. The current
+   design implementation does not address a possibility of introducing
+   additional fields (in future) to this structure without affecting
+   compatibility. Need to come up with the better approach to address this.
+   The possible approaches are:
+	1. Introduce version field for version tracking, bump up the version
+	whenever a new field is added to the structure in future. The version
+	field can be used to find out what fields are valid for the current
+	version of the structure.
+	2. Reserve the area of predefined size (say PAGE_SIZE) for this
+	structure and have unused area as reserved (initialized to zero)
+	for future field additions.
+   The advantage of approach 1 over 2 is we don't need to reserve extra space.

Subject: [PATCH 2804/6423] fadump: Reserve the memory for firmware assisted
 dump.

Reserve the memory during early boot to preserve CPU state data, HPTE region
and RMA (real mode area) region data in case of kernel crash. At the time of
crash, powerpc firmware will store CPU state data, HPTE region data and move
RMA region data to the reserved memory area.

If the firmware-assisted dump fails to reserve the memory, then fallback
to existing kexec-based kdump.

Most of the code implementation to reserve memory has been
adapted from phyp assisted dump implementation written by Linas Vepstas
and Manish Ahuja

This patch also introduces a config option CONFIG_FA_DUMP for firmware
assisted dump feature on Powerpc (ppc64) architecture.

Subject: [PATCH 2806/6423] fadump: Initialize elfcore header and add PT_LOAD
 program headers.

Build the crash memory range list by traversing through system memory during
the first kernel before we register for firmware-assisted dump. After the
successful dump registration, initialize the elfcore header and populate
PT_LOAD program headers with crash memory ranges. The elfcore header is
saved in the scratch area within the reserved memory. The scratch area starts
at the end of the memory reserved for saving RMR region contents. The
scratch area contains fadump crash info structure that contains magic number
for fadump validation and physical address where the eflcore header can be
found. This structure will also be used to pass some important crash info
data to the second kernel which will help second kernel to populate ELF core
header with correct data before it gets exported through /proc/vmcore. Since
the firmware preserves the entire partition memory at the time of crash the
contents of the scratch area will be preserved till second kernel boot.

Since the memory dump exported through /proc/vmcore is in ELF format similar
to kdump, it will help us to reuse the kdump infrastructure for dump capture
and filtering. Unlike phyp dump, userspace tool does not need to refer any
sysfs interface while reading /proc/vmcore.

NOTE: The current design implementation does not address a possibility of
introducing additional fields (in future) to this structure without affecting
compatibility. It's on TODO list to come up with better approach to
address this.

Subject: [PATCH 2807/6423] fadump: Convert firmware-assisted cpu state dump
 data into elf notes.

When registered for firmware assisted dump on powerpc, firmware preserves
the registers for the active CPUs during a system crash. This patch reads
the cpu register data stored in Firmware-assisted dump format (except for
crashing cpu) and converts it into elf notes and updates the PT_NOTE program
header accordingly. The exact register state for crashing cpu is saved to
fadump crash info structure in scratch area during crash_fadump() and read
during second kernel boot.

Subject: [PATCH 2808/6423] fadump: Add PT_NOTE program header for vmcoreinfo

Introduce a PT_NOTE program header that points to physical address of
vmcoreinfo_note buffer declared in kernel/kexec.c. The vmcoreinfo
note buffer is populated during crash_fadump() at the time of system
crash.

Subject: [PATCH 2809/6423] fadump: Introduce cleanup routine to invalidate
 /proc/vmcore.

With the firmware-assisted dump support we don't require a reboot when we
are in second kernel after crash. The second kernel after crash is a normal
kernel boot and has knowledge about entire system RAM with the page tables
initialized for entire system RAM. Hence once the dump is saved to disk, we
can just release the reserved memory area for general use and continue
with second kernel as production kernel.

Hence when we release the reserved memory that contains dump data, the
'/proc/vmcore' will not be valid anymore. Hence this patch introduces
a cleanup routine that invalidates and removes the /proc/vmcore file. This
routine will be invoked before we release the reserved dump memory area.

Subject: [PATCH 2810/6423] fadump: Invalidate registration and release
 reserved memory for general use.

This patch introduces an sysfs interface '/sys/kernel/fadump_release_mem' to
invalidate the last fadump registration, invalidate '/proc/vmcore', release
the reserved memory for general use and re-register for future kernel dump.
Once the dump is copied to the disk, unlike phyp dump, the userspace tool
can release all the memory reserved for dump with one single operation of
echo 1 to '/sys/kernel/fadump_release_mem'.

Release the reserved memory region excluding the size of the memory required
for future kernel dump registration. And therefore, unlike kdump, Fadump
doesn't need a 2nd reboot to get back the system to the production
configuration.

-                   Hypervisor-Assisted Dump
-                   ------------------------
-                       November 2007
-
-The goal of hypervisor-assisted dump is to enable the dump of
-a crashed system, and to do so from a fully-reset system, and
-to minimize the total elapsed time until the system is back
-in production use.
-
-As compared to kdump or other strategies, hypervisor-assisted
-dump offers several strong, practical advantages:
-
--- Unlike kdump, the system has been reset, and loaded
-   with a fresh copy of the kernel.  In particular,
-   PCI and I/O devices have been reinitialized and are
-   in a clean, consistent state.
--- As the dump is performed, the dumped memory becomes
-   immediately available to the system for normal use.
--- After the dump is completed, no further reboots are
-   required; the system will be fully usable, and running
-   in its normal, production mode on its normal kernel.
-
-The above can only be accomplished by coordination with,
-and assistance from the hypervisor. The procedure is
-as follows:
-
--- When a system crashes, the hypervisor will save
-   the low 256MB of RAM to a previously registered
-   save region. It will also save system state, system
-   registers, and hardware PTE's.
-
--- After the low 256MB area has been saved, the
-   hypervisor will reset PCI and other hardware state.
-   It will *not* clear RAM. It will then launch the
-   bootloader, as normal.
-
--- The freshly booted kernel will notice that there
-   is a new node (ibm,dump-kernel) in the device tree,
-   indicating that there is crash data available from
-   a previous boot. It will boot into only 256MB of RAM,
-   reserving the rest of system memory.
-
--- Userspace tools will parse /sys/kernel/release_region
-   and read /proc/vmcore to obtain the contents of memory,
-   which holds the previous crashed kernel. The userspace
-   tools may copy this info to disk, or network, nas, san,
-   iscsi, etc. as desired.
-
-   For Example: the values in /sys/kernel/release-region
-   would look something like this (address-range pairs).
-   CPU:0x177fee000-0x10000: HPTE:0x177ffe020-0x1000: /
-   DUMP:0x177fff020-0x10000000, 0x10000000-0x16F1D370A
-
--- As the userspace tools complete saving a portion of
-   dump, they echo an offset and size to
-   /sys/kernel/release_region to release the reserved
-   memory back to general use.
-
-   An example of this is:
-     "echo 0x40000000 0x10000000 > /sys/kernel/release_region"
-   which will release 256MB at the 1GB boundary.
-
-Please note that the hypervisor-assisted dump feature
-is only available on Power6-based systems with recent
-firmware versions.
-
-Implementation details:
-----------------------
-
-During boot, a check is made to see if firmware supports
-this feature on this particular machine. If it does, then
-we check to see if a active dump is waiting for us. If yes
-then everything but 256 MB of RAM is reserved during early
-boot. This area is released once we collect a dump from user
-land scripts that are run. If there is dump data, then
-the /sys/kernel/release_region file is created, and
-the reserved memory is held.
-
-If there is no waiting dump data, then only the highest
-256MB of the ram is reserved as a scratch area. This area
-is *not* released: this region will be kept permanently
-reserved, so that it can act as a receptacle for a copy
-of the low 256MB in the case a crash does occur. See,
-however, "open issues" below, as to whether
-such a reserved region is really needed.
-
-Currently the dump will be copied from /proc/vmcore to a
-a new file upon user intervention. The starting address
-to be read and the range for each data point in provided
-in /sys/kernel/release_region.
-
-The tools to examine the dump will be same as the ones
-used for kdump.
-
-General notes:
---------------
-Security: please note that there are potential security issues
-with any sort of dump mechanism. In particular, plaintext
-(unencrypted) data, and possibly passwords, may be present in
-the dump data. Userspace tools must take adequate precautions to
-preserve security.
-
-Open issues/ToDo:
-------------
- o The various code paths that tell the hypervisor that a crash
-   occurred, vs. it simply being a normal reboot, should be
-   reviewed, and possibly clarified/fixed.
-
- o Instead of using /sys/kernel, should there be a /sys/dump
-   instead? There is a dump_subsys being created by the s390 code,
-   perhaps the pseries code should use a similar layout as well.
-
- o Is reserving a 256MB region really required? The goal of
-   reserving a 256MB scratch area is to make sure that no
-   important crash data is clobbered when the hypervisor
-   save low mem to the scratch area. But, if one could assure
-   that nothing important is located in some 256MB area, then
-   it would not need to be reserved. Something that can be
-   improved in subsequent versions.
-
- o Still working the kdump team to integrate this with kdump,
-   some work remains but this would not affect the current
-   patches.
-
- o Still need to write a shell script, to copy the dump away.
-   Currently I am parsing it manually.

Subject: [PATCH 2813/6423] powerpc/perf: Move perf core & PMU code into a
 subdirectory

The perf code has grown a lot since it started, and is big enough to
warrant its own subdirectory. For reference it's ~60% bigger than the
oprofile code. It declutters the kernel directory, makes it simpler to
grep for "just perf stuff", and allows us to shorten some filenames.

While we're at it, make it more obvious that we have two implementations
of the core perf logic. One for (roughly) Book3S CPUs, which was the
original implementation, and the other for Freescale embedded CPUs.

 efx_for_each_possible_channel_tx_queue() to skip non-TX channels

efx_for_each_possible_channel_tx_queue() should do nothing for RX-only
or extra channels.  The current definition results in allocating
additional unused hardware TX queues when using the mqprio qdisc and
either separate_tx_channels or SR-IOV.

Subject: [PATCH 2815/6423] ppc-6xx: fix build failure in flipper-pic.c and
 hlwd-pic.c

The commit bae1d8f19983fbfa25559aa3cb6a81a84aa82a18 (linux-next)

  "irq_domain/powerpc: Use common irq_domain structure instead of irq_host"

made this change:

   -static struct irq_host *flipper_irq_host;
   +static struct irq_domain *flipper_irq_host;

and this change:

   -static struct irq_host *hlwd_irq_host;
   +static struct irq_domain *hlwd_irq_host;

The intent was to change the type, and not the name, but then in a
couple of instances, it looks like the sed to change the irq_domain_ops
name inadvertently also changed the irq_host name where it was not
supposed to, causing build failures.

Subject: [PATCH 2816/6423] xfs: cleanup quota check on disk blocks and inodes
 reservations

This patch is a cleanup of quota check on disk blocks and inodes
reservations, and changes it as follows.

(1) add a total_count variable to store the total number of
    current usages and new reservations for disk blocks and inodes,
    respectively.

(2) make it more readable to check if the local variables softlimit
    and hardlimit are positive. It has been changed as follows.
	    if (softlimit > 0ULL) -> if (softlimit)
	    if (hardlimit > 0ULL) -> if (hardlimit)
    This is because they are defined as xfs_qcnt_t which is unsigned.

Subject: [PATCH 2817/6423] xfs: split tail_lsn assignments from log space
 wakeups

Currently xfs_log_move_tail has a tail_lsn argument that is horribly
overloaded: it may contain either an actual lsn to assign to the log tail,
0 as a special case to use the last sync LSN, or 1 to indicate that no tail
LSN assignment should be performed, and we should opportunisticly wake up
at one task waiting for log space even if we did not move the LSN.

Remove the tail lsn assigned from xfs_log_move_tail and make the two callers
use xlog_assign_tail_lsn instead of the current variant of partially using
the code in xfs_log_move_tail and partially opencoding it.  Note that means
we grow an addition lock roundtrip on the AIL lock for each bulk update
or delete, which is still far less than what we had before introducing the
bulk operations.  If this proves to be a problem we can still add a variant
of xlog_assign_tail_lsn that expects the lock to be held already.

Also rename the remainder of xfs_log_move_tail to xfs_log_space_wake as
that name describes its functionality much better.

Subject: [PATCH 2818/6423] xfs: do exact log space wakeups in
 xlog_ungrant_log_space

The only reason that xfs_log_space_wake had to do opportunistic wakeups
was that the old xfs_log_move_tail calling convention didn't allow for
exact wakeups when not updating the log tail LSN.  Since this issue has
been fixed we can do exact wakeups now.

Subject: [PATCH 2819/6423] xfs: remove xfs_trans_unlocked_item

There is no reason to wake up log space waiters when unlocking inodes or
dquots, and the commit log has no explanation for this function either.

Given that we now have exact log space wakeups everywhere we can assume
the reason for this function was to paper over log space races in earlier
XFS versions.

Subject: [PATCH 2820/6423] xfs: cleanup xfs_log_space_wake

Remove the now unused opportunistic parameter, and use the the
xlog_writeq_wake and xlog_reserveq_wake helpers now that we don't have
to care about the opportunistic wakeups.

Subject: [PATCH 2821/6423] xfs: remove log space waitqueues

The tic->t_wait waitqueues can never have more than a single waiter
on them, so we can easily replace them with a task_struct pointer
and wake_up_process.

Subject: [PATCH 2828/6423] xfs: split and cleanup xfs_log_reserve

Split the log regrant case out of xfs_log_reserve into a separate function,
and merge xlog_grant_log_space and xlog_regrant_write_log_space into their
respective callers.  Also replace the XFS_LOG_PERM_RESERV flag, which easily
got misused before the previous cleanups with a simple boolean parameter.

Subject: [PATCH 2829/6423] tg3: Fix link check in tg3_adjust_link

The tg3 driver tried to detect link changes by comparing the tg3 local
active_speed member with SPEED_UNKNOWN (or formerly SPEED_INVALID).
This check is not correct, since phylib will never set its speed member
to either of these two values.  The code only appeared to work because
tg3 initializes active_speed to SPEED_INVALID during tg3_init_one.  This
patch introduces a new "old_link" tg3 member and then compares the
phy_device's link member against it to detect link state changes.

Subject: [PATCH 2830/6423] tg3: Remove SPEED_UNKNOWN checks

tg3_phy_copper_begin() has code that configures the link
advertisements through the use of the link_config.speed and
link_config.duplex members.  The driver does not internally use these
members in this way, nor is it (currently) permitted via the ethtool
interface.  This patch removes the dead code.

Subject: [PATCH 2831/6423] tg3: Clear RECOVERY_PENDING with reset_task_cancel

If an error happens in the tx completion thread, tg3_reset_task will be
scheduled and TX_RECOVERY_PENDING will be set.  The TX_RECOVERY_PENDING
flag causes tg3_poll[_msix] to return early before doing much of its
work.  Tg3_reset_task() gets canceled when the configuration of the
device is changing, which always results in a chip reset.  When this
happens, the TX_RECOVERY_PENDING flag may be left set, which would
unnecessarily hinder tg3_poll from doing work.  This patch fixes the
problem.

Subject: [PATCH 2832/6423] tg3: Create timer helper functions

This patch seeks to clean up the timer related code.  It begins by
moving one-time timer setup code from tg3_open() to tg3_init_one().
It then creates a function that encapsulates the code needed to start
the timer.  A tg3_timer_stop() function was added for parity.  Finally,
this patch moves all the timer functions to a more suitable location.

Subject: [PATCH 2833/6423] OMAPDSS: Remove video SRAM support

OMAP SRAM can be used as video memory on OMAP1 and 2. However, there
usually is very little SRAM available, thus limiting its use, and no
board supported by the kernel currently uses it.

This patch removes the use of SRAM as video ram for the omapdss driver
to simplify memory handling.

Subject: [PATCH 2836/6423] OMAP: N770: remove HWA742 platform data

In an effort to clean up the old omapfb driver, this patch removes
HWA742 (the display chip used in N770) platform data. This can be done
as N770 is the only user of HWA742, and the platform data contains only
one field, te_connected, which we can just presume to be true in the
HWA742 driver.

This allows us to remove omapfb_set_ctrl_platform_data(), and the
mechanism to pass the platform data, in a later patch.

Subject: [PATCH 2838/6423] OMAPFB: remove early mem alloc from old omapfb

arch/arm/plat-omap/fb.c contains code to alloc omapfb buffers at early
boot time according to information given from the bootloader or board
file.

This code isn't currently used by any board, and is anyway something
that the newer vram.c could handle. So remove the alloc code and in
later patches make old omapfb driver use vram.c.

Subject: [PATCH 2839/6423] OMAPFB: remove mem info from platform_data

omapfb driver used platform_data to get fb memory areas and formats
defined by the board file.

This patch removes omapfb's (both old and new omapfb) use of the
memory data in platform_data, because:

- No board uses them currently
- It's not board file's job to define things like amount of default
  framebuffer memory. These should come from the bootloader via command
  line parameters.

Subject: [PATCH 2843/6423] OMAP1: pass LCD config with omapfb_set_lcd_config()

LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board
files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this
patch adds omapfb_set_lcd_config() function that the board files can
call to set the LCD config.

This has the drawback that configuration can no longer come from the
bootloader. Of the boards supported by the kernel, this should only
affect N770 which depends on the data from the bootloader. This patch
adds an LCD config for N770 to its board files, but that is most
probably broken. Fixing this would need information about the HW setup
in N770 boards.

Some OMAP1 board files define LCD platform_devices, but there are no
corresponding LCD drivers for those in the kernel. Thus remove these LCD
devices.

Subject: [PATCH 2846/6423] OMAPFB: remove remaining OMAP arch checks

Now that the old omapfb driver is only omap1 display driver, there's no
need to check if the arch is omap1. This patch removes the few remaining
checks for the arch.

The ID is found on Asus K54HR and K53U.
Blacklist the AR3011-based device ID [0489:e03d]
and add to ath3k.c for firmware loading.

Below is the output of usb-devices script:

Subject: [PATCH 2852/6423] Bluetooth: Revert to mutexes from RCU list

Usage of RCU list looks not reasonalbe for a number of reasons:
our code sleep and we had to use socket spinlocks. Most parts
of code are updaters thus there is little sense to use RCU.

Subject: [PATCH 2858/6423] Bluetooth: mgmt: Make Set SSP command callable
 while powered off

This patch makes it possible to enable SSP through mgmt even when
powered off. The setting will then get automatically actiated when
powering on.

Otherwise subsequent attempts at setting the EIR to something valid

Subject: [PATCH 2867/6423] Bluetooth: mgmt: Implement Set LE command

This patch implements support for the Set LE mgmt command. Now, in
addition to the enable_le module parameter user space needs to send an
explicit Enable LE command to enable LE support.

Subject: [PATCH 2868/6423] Bluetooth: Fix EIR data clearing when powering off

When powering off we should assume that the EIR data isn't valid
anymore. This patch makes sure it gets cleared in hci_dev_do_close and
thereby ensures that a correct new EIR is recreated when powering on
again.

Subject: [PATCH 2869/6423] Bluetooth: mgmt: Fix updating EIR when updating the
 name

Whenever we update the local device name the EIR data also needs to be
updated to reflect this. The update_eir() function in mgmt.c depends on
hdev->dev_name to be up to date so the patch also makes sure that the
mgmt function is called from hci_event.c after the update has happened.

Subject: [PATCH 2874/6423] Bluetooth: Fix read_name updating when HCI_SETUP is
 not set

The local name should only be updated as a consequence of a
hci_read_local_name if we are in the HCI_SETUP state. In all other
scenarios it should only be updated through hci_write_local_name.

This patch makes it possible to set the local name before powering on
the device. The name will be applied using the hci_write_local_name
command once the device gets powered on.

Since we can't reliably track the short name changes just assume that we
had a change whenever there's a pending mgmt command. In the worst case
we just get one unnecessary name_changed signal.

Change sk lock to chan lock in l2cap core and move sk locks
to l2cap sock code. bh_locks were used because of being RCU
critical section. When needed use explicit socket locks.

Subject: [PATCH 2890/6423] Bluetooth: Set DISCOVERY_STOPPED if controller
 resets

If controller is reset during the discovery procedure, Start Discovery
command stops working. This can be easily reproduced by running
"hciconfig hci0 reset" while discovering devices, for instance.

We should force discovery state to DISCOVERY_STOPPED in case we receive
a reset command complete event. Otherwise we may stuck in one of the
active discovery states (DISCOVERY_INQUIRY, DISCOVERY_LE_SCAN and
DISCOVERY_RESOLVING) and subsequent Start Discovery commands will simply
fail.

Subject: [PATCH 2891/6423] Bluetooth: mgmt: Fix update_eir/class with
 HCI_AUTO_OFF flag set

If we're powered but still have the HCI_AUTO_OFF flag set the
update_eir and update_class functions should not do anything.
Additionally these functions need to be called when the flag is finally
cleared through set_powered or when powering on for real.

Change to STARTALIGN and pass align from start;  we are safe to do that
just as we do that regular pci bridge.  In the long run, we should just
treat cardbus like a regular pci bridge.

Also fix the case when realloc_head is not passed: we should keep the
requested size.

Subject: [PATCH 2901/6423] Bluetooth: mgmt: Move service cache setting to a
 more sensible place

Since we can now add UUIDs when powered off we don't really need to
always use the service cache to avoid large bursts of HCI commands.
Instead, the only important use case is when we're already powered and
user space starts to initialize itself. This can be easiest detected by
a "clear UUIDs" operation which is where this patch moves the service
cache setting.

Found debug print of class is shifted.

| pci 0000:f8:15.2: [8086:2b56] type 0 class 0x000600

Code is trying to print class with 6 digits, but use shifted class with
4 digits valid value as variable.

Change to original dev->class directly.

Also remove not needed calculating of local variable class, because it
will be updated after pci_fixup_device(pci_fixup_early...)

Also unify type print out when class and header is not matched.

Subject: [PATCH 2908/6423] PCI: Add pcie_hp=nomsi to disable MSI/MSI-X for
 pciehp driver

Add a parameter to avoid using MSI/MSI-X for PCIe native hotplug; it's
known to be buggy on some platforms.

In my environment, while shutting down, following stack trace is shown
sometimes.

  Disabling IRQ #16

An un-wanted interrupt is generated when PCI driver switches from
MSI/MSI-X to INTx while shutting down the device.  The interrupt does
not happen if MSI/MSI-X is not used on the device.
I confirmed that this problem does not happen if pcie_hp=nomsi was
specified and hotplug operation worked fine as usual.

v2: Automatically disable MSI/MSI-X against following device:
    PCI bridge: Integrated Device Technology, Inc. Device 807f (rev 02)
v3: Based on the review comment, combile the if statements.
v4: Removed module parameter.
    Move some code to build pciehp as a module.
    Move device specific code to driver/pci/quirks.c.
v5: Drop a device specific code until getting a vendor statement.

Subject: [PATCH 2909/6423] x86/mrst/pci: assign d3_delay to 0 for Langwell
 devices

Langwell devices are not true pci devices, they are not subject to the 10 ms
d3 to d0 delay required by pci spec. This patch assigns d3_delay to 0 for all
langwell pci devices.

We can also power off devices that are not really used by the OS

 pci device

ATOMISP on Medfield is a real PCI device which should be handled differently
than the fake PCI devices on south complex. PCI type 1 access is used for
accessing config space this also has other impact such as PM D3 delay. There
shouldn't be any need for reading base address from IUNIT via msg bus.

Subject: [PATCH 2913/6423] regmap: Remove default cache sync implementation

It's not used as all cache types have sync operations so it's just dead
code which never gets tested.

Subject: [PATCH 2914/6423] irq_domain/x86: Convert x86 (embedded) to use
 common irq_domain

This patch removes the x86-specific definition of irq_domain and replaces
it with the common implementation.

Subject: [PATCH 2915/6423] ethernet: unify return value of
 .ndo_set_mac_address if address is invalid

Unify return value of .ndo_set_mac_address if the given address
isn't valid. Return -EADDRNOTAVAIL as eth_mac_addr() already does
if is_valid_ether_addr() fails.

This patch adds a flag to track pending changes to the class of device.
This is needed since we cannot cleanly handle multiple simultaneous

that might trigger a class change.

 response timing

All mgmt commands that may fire off a hci_write_class_of_device command
should wait for the completion of the HCI command before sending a
response to user space.

Subject: [PATCH 2924/6423] Bluetooth: mgmt: Fix clear_uuids response

Since the clear_uuids operation doesn't send an immediate HCI command
but just sets off a timer to wait for subsequent add_uuid calls it
doesn't make sense to wait until the timer fires off to send the
response. Instead send the response immediately.

Subject: [PATCH 2926/6423] drivers/video/pxa168fb.c: use devm_ functions

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

By using devm_ioremap, it also removes a potential memory leak, because
there was no call to iounmap in the probe function.

Date: Sun, 12 Feb 2012 13:24:25 -0800
Subject: [PATCH 2928/6423] x86, efi: Refactor efi_init() a bit

Break out some of the init steps into helper functions.

Only change to execution flow is the removal of the warning when the
kernel memdesc structure differ in size from what firmware specifies
since it's a bogus warning (it's a valid difference per spec).

v4:
* Removed memdesc warning as per above

Subject: [PATCH 2931/6423] x86, efi: Add basic error handling

It's not perfect, but way better than before. Mark efi_enabled as false in
case of error and at least stop dereferencing pointers that are known to
be invalid.

The only significant missing piece is the lack of undoing the
memblock_reserve of the memory that efi marks as in use. On the other
hand, it's not a large amount of memory, and leaving it unavailable for
system use should be the safer choice anyway.

From 1adbfa3511ee1c1118e16a9a0246870f12fef4e6 Mon Sep 17 00:00:00 2001
From: Olof Johansson <olof@lixom.net>
Date: Sun, 12 Feb 2012 13:24:29 -0800
Subject: [PATCH 2932/6423] x86, efi: Allow basic init with mixed 32/64-bit
 efi/kernel

Traditionally the kernel has refused to setup EFI at all if there's been
a mismatch in 32/64-bit mode between EFI and the kernel.

On some platforms that boot natively through EFI (Chrome OS being one),
we still need to get at least some of the static data such as memory
configuration out of EFI. Runtime services aren't as critical, and
it's a significant amount of work to implement switching between the
operating modes to call between kernel and firmware for thise cases. So
I'm ignoring it for now.

v5:
* Fixed some printk strings based on feedback
* Renamed 32/64-bit specific types to not have _ prefix
* Fixed bug in printout of efi runtime disablement

v4:
* Some of the earlier cleanup was accidentally reverted by this patch, fixed.
* Reworded some messages to not have to line wrap printk strings

v3:
* Reorganized to a series of patches to make it easier to review, and
  do some of the cleanups I had left out before.

v2:
* Added graceful error handling for 32-bit kernel that gets passed
  EFI data above 4GB.
* Removed some warnings that were missed in first version.

Subject: [PATCH 2933/6423] PCI: make pci_flags always available

If we move resource assignment functions into the core, we'll still
need a way for architectures to prevent reassignment, e.g., the
"pci_probe_only" functionality, and we'll need a generic, always
available way the core can test for that.  The "pci_flags"
arrangement used by several architectures seems like a convenient
way to do this.

Subject: [PATCH 2936/6423] arm/PCI: remove arch pci_flags definition

The PCI core provides a pci_flags definition (currently __weak), so drop
the arm definition in favor of that.

We EXPORT_SYMBOL(pci_flags) as arm did previously.  I'm dubious about
this: no other architecture exports it, and I didn't see any modules in
the tree that reference it.

pci_flags is initialized to zero and never modified (I think this was just

"!(pci_flags & XX)" is always true, and we can remove all references

Subject: [PATCH 2940/6423] mips/PCI: removed unused pci_probe configurability

We never assign anything other than PCI_ASSIGN_ALL_BUSSES to pci_probe,
so just remove the indirection.  If configurability is required in the
future, please use the pci_flags/PCI_REASSIGN_ALL_BUS functionality
as is done for powerpc.

Subject: [PATCH 2941/6423] powerpc/PCI: make pci_probe_only default to 0

pci_probe_only is set on ppc64 to prevent resource re-allocation
by the core. It's meant to be used in very specific circumstances
such as when operating under a hypervisor that may prevent such
re-allocation.

Instead of default to 1, we make it default to 0 and explicitly
set it in the few cases where we need it.

This fixes FSL PCI which wants it clear among others.

Subject: [PATCH 2942/6423] powerpc/PCI: replace pci_probe_only with pci_flags

We already use pci_flags, so this just sets pci_flags directly and removes
the intermediate step of figuring out pci_probe_only, then using it to set
pci_flags.

The PCI core provides a pci_flags definition (currently __weak), so drop
the powerpc definitions in favor of that.

Subject: [PATCH 2945/6423] PCI: don't publish new root bus until it's fully
 initialized

When pci_create_root_bus() adds the new struct pci_bus to the global
pci_root_buses list, the bus becomes visible to other parts of the
kernel, so it should be fully initialized.

This patch delays adding the bus to the pci_root_buses list until after
all the struct pci_bus initialization is finished.

Subject: [PATCH 2947/6423] PCI: add struct pci_host_bridge_window with CPU/bus
 address offset

Some PCI host bridges apply an address offset, so bus addresses on PCI are
different from CPU addresses.  This patch adds a way for architectures to
tell the PCI core about this offset.  For example:

    LIST_HEAD(resources);
    pci_add_resource_offset(&resources, host->io_space, host->io_offset);
    pci_add_resource_offset(&resources, host->mem_space, host->mem_offset);
    pci_scan_root_bus(parent, bus, ops, sysdata, &resources);

Subject: [PATCH 2948/6423] PCI: convert bus addresses to resource when reading
 BARs

Some PCI host bridges translate CPU addresses to PCI bus addresses.
Previously, we initialized pci_dev resources with PCI bus addresses,
then converted them to CPU addresses later in arch-specific code
(pcibios_fixup_resources()), which leaves a window of time where the
pci_dev resources are incorrect.

This patch adds support in the core for this address translation.
When the arch creates the root bus, it can supply the host bridge
address translation information, and the core can use it to set the
pci_dev resources correctly from the beginning.

This gives us a way to fix the problem that quirks that run between device
discovery and pcibios_fixup_resources() fail because they use pci_dev
resources that haven't been converted.  The reference below is to one
such problem that affected ARM and ia64.

Note that this patch has no effect until an arch starts using
pci_add_resource_offset() with a non-zero offset: before that, all
all host bridge windows have a zero offset and pci_bus_to_resource()
copies the pci_bus_region directly to the struct resource.

pcibios_bus_to_resource() in asm-generic/pci.h with versions that use
pci_resource_to_bus() and pci_bus_to_resource().

The replacements are equivalent except that they can apply host
bridge window offsets when the arch has supplied them by using
pci_add_resource_offset().

Each arch can convert to using pci_add_resource_offset() individually by
removing its device resource fixups from pcibios_fixup_bus() and supplying
ARCH_HAS_GENERIC_PCI_OFFSETS.  ARCH_HAS_GENERIC_PCI_OFFSETS can be removed
after all have converted.

Subject: [PATCH 2952/6423] ia64/PCI: SN: convert to pci_scan_root_bus() for
 correct root bus resources

Convert from pci_scan_bus() to pci_scan_root_bus().  Supply the root
bus resources from bussoft.  When we move the resource adjustment from
pcibios_fixup_resources() to the PCI core, it will be important to have
the root bus resources correct from the beginning.

Subject: [PATCH 2955/6423] mips/PCI: get rid of device resource fixups

Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

Here's the wrinkle on Cobalt: we can't generate normal I/O port addresses
on PCI because the GT-64111 doesn't do any address translation, so we have
this:

  CPU I/O port addresses		[io 0x0000-0xffffff]
  PCI bus I/O port addresses	[io 0x10000000-0x10ffffff]

Legacy-mode IDE controllers start out with the legacy bus addresses, e.g.,
0x1f0, assigned by pci_setup_device().  These are outside the range of
addresses GT-64111 can generate on PCI, but pcibios_fixup_device_resources()
converted them to CPU addresses anyway by adding io_offset.  Therefore, we
had to pre-adjust them in cobalt_legacy_ide_fixup().

With io_offset = 0xf0000000, we had this:

  res->start = 0x1f0	initialized in pci_setup_device()
  res->start = 0x100001f0	-= io_offset in cobalt_legacy_ide_fixup()
  res->start = 0x1f0	+= io_offset in pcibios_fixup_device_resources()

The difference after this patch is that the generic pci_bus_to_resource()
only adds the offset if the bus address is inside a host bridge window.
Since 0x1f0 is not a valid bus address and is not inside any windows, it is
unaffected, so we now have this:

  region->start = 0x1f0	initialized in pci_setup_device()
  res->start = 0x1f0	no offset by pci_bus_to_resource()

That means we can remove both pcibios_fixup_device_resources() and
cobalt_legacy_ide_fixup().

I would *rather* set the host bridge offset to zero (which corresponds
to what the GT-64111 actually does), and have both CPU and PCI addresses
of [io 0x10000000-0x10ffffff].  However, that would require changes to
generic code that assumes legacy I/O addresses, such as pic1_io_resource
([io 0x0020-0x00021]), and we'd have to keep a Cobalt IDE fixup.

Of course, none of this changes the fact that references to I/O port
0x1f0 actually go to port 0x100001f0, not 0x1f0, on the Cobalt PCI bus.
Fortunately the VT82C586 IDE controller only decodes the low 24 address
bits, so it does work.

Subject: [PATCH 2960/6423] sparc/PCI: get rid of device resource fixups

Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

N.B. Leon apparently never uses initial BAR values, so it didn't matter
that we never fixed up the I/O resources from bus address to CPU addresses.

Other sparc uses pci_of_scan_bus(), which sets device resources directly
to CPU addresses, not bus addresses, so it didn't need pcibios_fixup_bus()
either.  But by telling the core about the offsets, we can nuke
pcibios_resource_to_bus().

Subject: [PATCH 2962/6423] PCI: collapse pcibios_resource_to_bus

Everybody uses the generic pcibios_resource_to_bus() supplied by the core
now, so remove the ARCH_HAS_GENERIC_PCI_OFFSETS used during conversion.

Subject: [PATCH 2963/6423] pinctrl: disallow map table entries with NULL
 dev_name field

Hog entries are mapping table entries with .ctrl_dev_name == .dev_name.
All other mapping table entries need .dev_name set so that they will
match some pinctrl_get() call. All extant PIN_MAP*() macros set
.dev_name.

So, there is no reason to allow mapping table entries without .dev_name
set. Update the code and documentation to disallow this.

Subject: [PATCH 2966/6423] pinctrl: remove pin and hogs locks from struct
 pinctrl_dev

struct pinctrl_dev's pin_desc_tree_lock and pinctrl_hogs_lock aren't
useful; the data they protect is read-only except when registering or
unregistering a pinctrl_dev, and at those times, it doesn't make sense to
protect one part of the structure independently from the rest.

Move pinctrl_init_device_debugfs() to the end of pinctrl_register() so
that debugfs can't access the struct pinctrl_dev until it's fully
initialized, i.e. after the hogs are set up.

Subject: [PATCH 2972/6423] davinci_cpdma: Fix channel number written to
 teardown registers

chan->chan_num is 0..CPDMA_MAX_CHANNELS-1 for tx channels and
CPDMA_MAX_CHANNELS..2*CPDMA_MAX_CHANNELS-1 for rx channels. However,
the rx and tx teardown registers expect zero based channel numbering.

Since the upper bits of the registers are reserved, the teardown also
worked before, this patch is cleanup only.

Subject: [PATCH 2976/6423] net: Support RXFCS feature flag.

When set on hardware that supports the feature,
this causes the Ethernet FCS to be appended
to the end of the skb.

Useful for sniffing packets.

Subject: [PATCH 2977/6423] e1000e: Support RXFCS feature flag.

This enables enabling/disabling reception of the Ethernet
FCS.  This can be useful when sniffing packets.

For e1000e, enabling RXFCS can change the default
behaviour for how the NIC handles CRC.  Disabling RXFCS
will take the NIC back to defaults, which can be configured
as part of the module options.

Subject: [PATCH 2980/6423] net: Support RX-ALL feature flag.

This flag requests that network devices pass all
received frames up the stack, even ones with errors
such as invalid FCS (frame check sum).  This will
allow sniffers to see bad packets and perhaps
give the user some idea how to fix the problem.

Subject: [PATCH 2986/6423] r8169: Support RX-ALL flag.

This allows the NIC to receive packets with bad FCS and
Runts, which can help when sniffing.

NOTE:  r8169, at least on my NIC, silently drops packets
with bad FCS instead of counting them.  It seems they are
only received in any fashion if the RxCRC flag is set
(which this patch allows).

Subject: [PATCH 2990/6423] e1000: Neaten e1000_config_dsp_after_link_change

Separate a complicated bit of e1000_config_dsp_after_link_change
into a new static function e1000_1000Mb_check_cable_length.

Reduces indentation and adds a bit of clarity.

The reason of above dump message is calling dma_poll_alloc with can-schedule
mem_flags at atomic context.

To fix this problem, below changes are made:
- fsl_req_to_dtd doesn't need to be protected by spin_lock_irqsave,
as struct usb_request can be access at process context. Move lock
to beginning of hardware visit (fsl_queue_td).
- Change the memory flag which using to allocate dTD descriptor buffer,
the memory flag can be from gadget layer.

It is tested at i.mx51 bbg board with g_mass_storage, g_ether, g_serial.

Subject: [PATCH 2995/6423] usb: musb: Reselect index reg in interrupt context

musb INDEX register is getting modified/corrupted during temporary
un-locking in a SMP system. Set this register with proper value
after re-acquiring the lock

Scenario:
---------
CPU1 is handling a data transfer completion interrupt received for
the CLASS1 EP
CPU2 is handling a CLASS2 thread which is queuing data to musb for
transfer

Below is the error sequence:

         CPU1                   |             CPU2

Interrupt for Class1 EP schedul-|
es the next data transfer       |
but musb INDEX register is still|
set to CLASS2 EP                |

Since the MUSB INDEX register is set to a different endpoint, we
read and modify the wrong registers. Hence data transfer will not
happen properly. This results in unpredictable behavior

So, the MUSB INDEX register is set to proper value again when
interrupt re-acquires the lock

With Bluetooth 1.1 controllers the last command in the HCI init sequence

init request completion in this case. This patch fixes the issue by
adding the necessary callback to the write_local_name_complete handler.

SET_SYSTEM_SLEEP_PM_OPS writes .poweroff = *_resume once. Then we overwrite it
again explicitly as .poweroff = snd_soc_poweroff. Even though it works, as the
second one overwrites the first one, this is not the correct way. Fix this by
expanding SET_SYSTEM_SLEEP_PM_OPS in our structure.

In order to allow us to support partial sync operations add minimum and

obviously not good, we could exit the iteration earlier, but there may
be room for more wide reaching optimisation there.

Subject: [PATCH 3000/6423] regmap: Allow drivers to sync only part of the
 register cache

Provide a regcache_sync_region() operation which allows drivers to
write only part of the cache back to the hardware. This is intended
for use in cases like power domains or DSP memories where part of the
device register map may be reset without fully resetting the device.

Fully supporting these devices is likely to require additional work to
make specific regions of the register map cache only while they are in
reset, but this is enough for most devices.

and clear 00:1c.0 to retry again.

This patch removes IORESOUCE_IO checking, and tries one more time.  It
gives us a chance to get an allocation for the 00:1c.0 io port range
because the range from 0x4000 to 0x8000 will be freed and we can use it.

Subject: [PATCH 3003/6423] irq_domain/mips: Allow irq_domain on MIPS

This patch makes IRQ_DOMAIN usable on MIPS.  It uses an ugly workaround
to preserve current behaviour so that MIPS has time to add irq_domain
registration to the irq controller drivers.  The workaround will be
removed in Linux v3.6

Subject: [PATCH 3004/6423] PCI: prepare pci=realloc for multiple options

Let the user could enable and disable with pci=realloc=on or pci=realloc=off

Also
1. move variable and functions near the place they are used.
2. change macro to function
3. change related functions and variable to static and _init
4. update parameter description accordingly.

This will let us add a config option to control default behavior, and
still allow the user to turn off automatic reallocation if it fails on
their platform until a permanent solution is found.

-v2: still honor pci=realloc, and treat it as pci=realloc=on
     also use enum instead of ...
-v3: update kernel-paramenters.txt according to Jesse.

+OZWPAN USB Host Controller Driver
+---------------------------------
+This driver is a USB HCD driver that does not have an associated a physical
+device but instead uses Wi-Fi to communicate with the wireless peripheral.
+The USB requests are converted into a layer 2 network protocol and transmitted
+on the network using an ethertype (0x892e) regestered to Ozmo Device Inc.
+This driver is compatible with existing wireless devices that use Ozmo Devices
+technology.
+
+To operate the driver must be bound to a suitable network interface. This can
+be done when the module is loaded (specifying the name of the network interface
+as a paramter - e.g. 'insmod ozwpan g_net_dev=go0') or can be bound after
+loading using an ioctl call. See the ozappif.h file and the ioctls
+OZ_IOCTL_ADD_BINDING and OZ_IOCTL_REMOVE_BINDING.
+
+The devices connect to the host use Wi-Fi Direct so a network card that supports
+Wi-Fi direct is required. A recent version (0.8.x or later) version of the
+wpa_supplicant can be used to setup the network interface to create a persistent
+autonomous group (for older pre-WFD peripherals) or put in a listen state to
+allow group negotiation to occur for more recent devices that support WFD.
+
+The protocol used over the network does not directly mimic the USB bus
+transactions as this would be rather busy and inefficient. Instead the chapter 9
+requests are converted into a request/response pair of messages. (See
+ozprotocol.h for data structures used in the protocol).

+ *
+ * This file provides the implementation of a USB host controller device that
+ * does not have any associated hardware. Instead the virtual device is
+ * connected to the WiFi network and emulates the operation of a USB hcd by
+ * receiving and sending network frames.
+ * Note:
+ * We take great pains to reduce the amount of code where interrupts need to be
+ * disabled and in this respect we are different from standard HCD's. In
+ * particular we don't want in_irq() code bleeding over to the protocol side of
+ * the driver.
+ * The troublesome functions are the urb enqueue and dequeue functions both of
+ * which can be called in_irq(). So for these functions we put the urbs into a
+ * queue and request a tasklet to process them. This means that a spinlock with
+ * interrupts disabled must be held for insertion and removal but most code is
+ * is in tasklet or soft irq context. The lock that protects this list is called
+ * the tasklet lock and serves the purpose of the 'HCD lock' which must be held
+ * when calling the following functions.
+ *   usb_hcd_link_urb_to_ep()
+ *   usb_hcd_unlink_urb_from_ep()
+ *   usb_hcd_flush_endpoint()
+ *   usb_hcd_check_unlink_urb()

Subject: [PATCH 3010/6423] staging: ozwpan: Added USB service to protocol

The L2 protocol supports various services, one of which is USB.
This provides the implementation of that service and plumbs it to
the virtual USB HCD.

Date: Mon, 20 Feb 2012 21:12:27 +0000
Subject: [PATCH 3012/6423] staging: ozwpan: Added event logging support

The event logging subsystem allows internal events in the driver to
be logged. This facilitates testing the correct operation of the
driver. This subsystem is optional and can be switched out at
compile time.

Subject: [PATCH 3015/6423] PCI: add a PCI resource reallocation config option

Add a new config option, PCI_REALLOC_ENABLE_AUTO, which will
automatically try to re-allocate PCI resources if PCI_IOV support is
enabled and the SR-IOV resources are unassigned.  Behavior can still be
controlled using the pci=realloc= parameter.

-v2: According to Jesse, adding one CONFIG option for distribution to
     disable it or enable it.
-v3: update Kconfig text (jbarnes)

Subject: [PATCH 3020/6423] bitops: Add missing parentheses to new get_order
 macro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The new get_order macro introcuded in commit

	d66acc39c7cee323733c8503b9de1821a56dff7e

does not use parentheses around all uses of the parameter n.
This causes new compile warnings, for example in the
amd_iommu_init.c function:

drivers/iommu/amd_iommu_init.c:561:6: warning: suggest parentheses around comparison in operand of ‘&’ [-Wparentheses]
drivers/iommu/amd_iommu_init.c:561:6: warning: suggest parentheses around comparison in operand of ‘&’ [-Wparentheses]

Fix those warnings by adding the missing parentheses.

Subject: [PATCH 3021/6423] x86-64: Fix CFI annotations for NMI nesting code

The saving and restoring of %rdx wasn't annotated at all, and the
jumping over sections where state gets partly restored wasn't handled
either.

Further, by folding the pushing of the previous frame in repeat_nmi
into that which so far was immediately preceding restart_nmi (after
moving the restore of %rdx ahead of that, since it doesn't get used
anymore when pushing prior frames), annotations of the replicated
frame creations can be made consistent too.

v2: Fully fold repeat_nmi into the normal code flow (adding a single
    redundant instruction to the "normal" code path), thus retaining
    the special protection of all instructions between repeat_nmi and
    end_repeat_nmi.

Subject: [PATCH 3022/6423] x86-64: Improve insn scheduling in SAVE_ARGS_IRQ

In one case, use an address register that was computed earlier (and
with a simpler instruction), thus reducing the risk of a stall.

In the second case, eliminate a branch by using a conditional move (as
is already done in call_softirq and xen_do_hypervisor_callback).

Subject: [PATCH 3028/6423] staging/mei: mei-amt-version - make all function
 static and used

This patch eliminates following type of warnings
warning: no previous prototype for '...func...' [-Wmissing-prototypes]

For this is a single file example lets make all API-like functions
be static.
Since all static functions should be used so let's call
to amt_host_if_deinit() even if in this example it's not really necessary

New kernel developer inspired by the 2010 FOSDEM talk. Running checkpatch on
p80211netdev.c gave the error: p80211netdev.c:153: ERROR: "foo * bar" should
be "foo *bar". Fixed it by doing what was suggested.

Due to some conflicting debug vars, kernel build will warn when
CONFIG_RAMSTER=y and CONFIG_OCFS2=m and will fail when
CONFIG_RAMSTER=y and CONFIG_OCFS2=y (rare).

Rename ramster mlog vars to avoid the name conflict.

Subject: [PATCH 3032/6423] staging: ramster: Dont build ramster when
 CONFIGFS_FS=m

Ramster can't be a module (yet) and depends on CONFIGFS_FS=y, but
allmodconfig builds with CONFIGFS_FS=m, which breaks the build.
And forcing CONFIGFS_FS=y with select breaks the build in other ways.
So just don't build ramster unless CONFIGFS_FS=y.

Also, while we're here, add a comment as to why BROKEN is depended.

Subject: [PATCH 3033/6423] staging: et131x: use netif_rx_ni() for packet
 receive

netif_rx is meant to be called from interrupts because it doesn't wake
up ksoftirqd.  For calling from outside interrupts, netif_rx_ni exists.

This stops the error "NOHZ: local_softirq_panding 08" that happens on
some machines with NOHZ and plip --- it is caused by the fact that
softirq is pending and ksoftirqd is sleeping.

Subject: [PATCH 3034/6423] staging: zcache: avoid AB-BA deadlock condition

Commit 9256a47 fixed a deadlock condition, being sure that the buddy
list spinlock is always taken before the page spinlock.

However in zbud_free_and_delist() locking order is the opposite
(page lock -> list lock).

Possible unsafe locking scenario (reported by lockdep):

        CPU0                    CPU1
        ----                    ----
   lock(&(&zbpg->lock)->rlock);
                                lock(zbud_budlists_spinlock);
                                lock(&(&zbpg->lock)->rlock);
   lock(zbud_budlists_spinlock);

Fix by grabbing the locks in opposite order in zbud_free_and_delist().

Subject: [PATCH 3038/6423] Staging: wlan-ng: memsetting the wrong amount of
 data

p80211item_pstr6_t is the size of "msg1.bssid" (16 bytes) but
msg1.bssid.data is type p80211pstr6_t and it is smaller (7 bytes).  We
had just set that memory to zeroes earlier and now we're writing over it
with 0xff because we're writing past the end of the struct.

I don't know if this actually causes a problem.  It may be that we
initialize the extra 0xff bytes correctly later.  But the current code
is obviously wrong and we should fix it.

Subject: [PATCH 3044/6423] staging: tidspbridge: always compile dsp wdt code

In order to detect it at runtime, we need the code handling wdt
clock available at runtime to decide whether to enable or disable
based on the baseimage symbols. Default timeout has been set to 5
seconds.

Downside is that we will lose the option to set a custom timeout
for overflow, but than can be added (if needed) as part of debugfs.

Subject: [PATCH 3045/6423] staging: tidspbridge: detect wdt3 feature at
 runtime

In order to detect WDT feature on the dsp code, we need to
find the symbol used to enable it inside the baseimage.

This should fix the warning comming from L3 driver:

    WARNING: at arch/arm/mach-omap2/omap_l3_smx.c:161 omap3_l3_app_irq...
    In-band Error seen by IVA_SS  at address 0
    ...

That occurs because the dsp tries to access wdt3 registers when the clock
for those registers is not enabled.

Subject: [PATCH 3046/6423] staging:iio:core set the iio_dev.info pointer to
 null on unregister under lock.

This prevents use of provider callbacks after it has been unregistered.
Note that all code using this that can be called from a consumer *must*
check the pointer before using and hold the info_exist_lock throughout
the usage of the callbacks in info.

From: Jonathan Cameron <jic23@cam.ac.uk>
Date: Wed, 15 Feb 2012 19:48:01 +0000
Subject: [PATCH 3047/6423] staging:iio:core add in kernel interface mapping
 and getting IIO channels.

Lifted from proposal for in kernel interface built on the out of staging
branch.

Two elements here:
* Map as defined in "inkern.h"
* Matching code to actually get the iio_dev and channel
that we want from the global list of IIO devices.
V4: Everything now built if iio is built (rather than being optional)
    Removal race condition prevented by using info pointer as a check
    of removal under a lock.
V3: Drop the option of registering / getting channels using dev pointer.
Stick to name only as suggested by Mark Brown (this has caused user
confusion in the regulator framework.)
V2: As per Greg KH suggestion, move over to registration by passing
the tables into the provider drivers (how regulator does it).
This does not prevent us using the original more flexible approach
if at a later date there is a usecase that demands it.

Subject: [PATCH 3049/6423] staging:iio::hwmon interface client driver.

Direct copy of version proposed for the non staging branch.
Needed here to allow testing of more advanced inkernel
interface code.

Minimal support of simple in, curr and temp attributes
so far.

+Industrial I/O Subsystem in kernel consumers.
+
+The IIO subsystem can act as a layer under other elements of the kernel
+providing a means of obtaining ADC type readings or of driving DAC type
+signals.  The functionality supported will grow as use cases arise.
+
+Describing the channel mapping (iio/machine.h)
+
+Channel associations are described using:
+
+struct iio_map {
+	const char *adc_channel_label;
+	const char *consumer_dev_name;
+	const char *consumer_channel;
+};
+
+adc_channel_label identifies the channel on the IIO device by being
+matched against the datasheet_name field of the iio_chan_spec.
+
+consumer_dev_name allows identification of the consumer device.
+This are then used to find the channel mapping from the consumer device (see
+below).
+
+Finally consumer_channel is a string identifying the channel to the consumer.
+(Perhaps 'battery_voltage' or similar).
+
+An array of these structures is then passed to the IIO driver.
+
+Supporting in kernel interfaces in the driver (driver.h)
+
+The driver must provide datasheet_name values for its channels and
+must pass the iio_map structures and a pointer to its own iio_dev structure
+ on to the core via a call to iio_map_array_register.  On removal,
+iio_map_array_unregister reverses this process.
+
+The result of this is that the IIO core now has all the information needed
+to associate a given channel with the consumer requesting it.
+
+Acting as an IIO consumer (consumer.h)
+
+The consumer first has to obtain an iio_channel structure from the core
+by calling iio_channel_get().  The correct channel is identified by:
+
+* matching dev or dev_name against consumer_dev and consumer_dev_name
+* matching consumer_channel against consumer_channel in the map
+
+There are then a number of functions that can be used to get information
+about this channel such as it's current reading.
+
+e.g.
+iio_st_read_channel_raw() - get a reading
+iio_st_read_channel_type() - get the type of channel
+
+There is also provision for retrieving all of the channels associated
+with a given consumer.  This is useful for generic drivers such as
+iio_hwmon where the number and naming of channels is not known by the
+consumer driver.  To do this, use iio_st_channel_get_all.

Subject: [PATCH 3051/6423] staging:iio: Use dev_pm_ops

Use dev_pm_ops instead of legacy suspend/resume callbacks for IIO drivers.

Note that this patch introduces a few new #ifdef CONFIG_PM_SLEEP around the
suspend and resume callbacks to avoid warnings of unused functions if
CONFIG_PM_SLEEP is not defined.

Subject: [PATCH 3053/6423] staging:iio: Add extended IIO channel info

Sometimes devices have per channel properties which either do not map nicely to
the current channel info scheme (e.g. string properties) or are very device
specific, so it does not make sense to add generic support for them.

Currently drivers define these attributes by hand for each channel. Depending on
the number of channels this can amount to quite a few lines of boilerplate code.
Especially if a driver supports multiple variations of a chip with different
numbers of channels. In this case it becomes necessary to have a individual
attribute list per chip variation and also a individual iio_info struct.

This patch introduces a new scheme for handling such per channel attributes
called extended channel info attributes. A extended channel info attribute
consist of a name, a flag whether it is shared and read and write callbacks.
The read and write callbacks are similar to the {read,write}_raw callbacks and
take a IIO device and a channel as their first parameters, but instead of
pre-parsed integer values they directly get passed the raw string value, which
has been written to the sysfs file.

It is possible to assign a list of extended channel info attributes to a
channel. For each extended channel info attribute the IIO core will create a new
sysfs attribute conforming to the IIO channel naming spec for the channels type,
similar as for normal info attributes. Read and write access to this sysfs
attribute will be redirected to the extended channel info attributes read and
write callbacks.

Subject: [PATCH 3054/6423] staging:iio:dac:ad5064: Convert to extended channel
 info attributes

Use extended channel info attributes for the powerdown, powerdown_mode and
powerdown_mode_available attributes.

Note that this patch moves the chip info defintion around to avoid having to use
forward declarations for the extended channel info attributes callbacks.

Subject: [PATCH 3055/6423] staging:iio:dac:ad5064: Prepare driver for the
 addition of chip variants

Prepare the driver for the addition of chip variants with a different number of
channels. This is done by not hard-coding the number of channels, but instead
add a field to the chip info struct holding the number of channels. Also do not
embed the channel specs into the chip info, but rather store them independently.
This allows sharing the same channel spec between different chip infos.

Date: Wed, 22 Feb 2012 13:16:49 +0100
Subject: [PATCH 3060/6423] iio: core: constitfy available_scan_mask

The core must not modify available_scan_mask, because it causes problems
with drivers where multiple instances of the driver share the same mask set.
So make this explicit by marking available scan masks as const.

The max1363 driver needs some minor adjustment to accommodate this change.
Pull scan mask allocation into a separate function.

Subject: [PATCH 3061/6423] usb-serial: new API for driver registration

This patch (as1522) adds two new routines to the usb-serial core, for
registering and unregistering serial drivers.  Instead of registering
the usb_driver and usb_serial_drivers separately, with error checking
for each one, the drivers can all be registered and unregistered by a
single function call.  This reduces duplicated code.

More importantly, the new core routines change the order in which the
drivers are registered.  Currently the usb-serial drivers are all
registered first and the usb_driver is done last, which leaves a
window for problems.  A udev script may quickly add a new dynamic-ID
for a usb-serial driver, causing the corresponding usb_driver to be
probed.  If the usb_driver hasn't been registered yet then an oops
will occur.

The new routine prevents such problems by registering the usb_driver
first.  To insure that it gets probed properly for already-attached
serial devices, we call driver_attach() after all the usb-serial
drivers have been registered.

Along with adding the new routines, the patch modifies the "generic"
serial driver to use them.  Further patches will similarly modify all
the other in-tree USB serial drivers.

From 4d2a7aff1062048ea59214b49ca1d915586d6d6d Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>
Date: Thu, 23 Feb 2012 14:57:09 -0500
Subject: [PATCH 3065/6423] usb-serial: use new registration API in [k-m]*
 drivers

This patch (as1526) modifies the following usb-serial drivers to
utilize the new usb_serial_{de}register_drivers() routines:

	keyspan, kl5kusb105, kobil_sct, mct_u232, mos7720,
	mos7840, and moto_modem.

From f667ddad41e303ebc2c6d5bf3105dffe2fbdd717 Mon Sep 17 00:00:00 2001
From: Alan Stern <stern@rowland.harvard.edu>
Date: Thu, 23 Feb 2012 14:57:18 -0500
Subject: [PATCH 3066/6423] usb-serial: use new registration API in [n-p]*
 drivers

This patch (as1527) modifies the following usb-serial drivers to
utilize the new usb_serial_{de}register_drivers() routines:

	navman, omninet, opticon, option, oti6858, and pl2303.

Subject: [PATCH 3069/6423] usb-serial: use new registration API in staging
 drivers

This patch (as1530) modifies the following usb-serial drivers from
drivers/staging to utilize the new usb_serial_{de}register_drivers()
routines:

	quatech_usb2 and serqt_usb2.

Subject: [PATCH 3071/6423] cirrus/mac89x0: print MAC via printk format
 specifier

Print MAC/dev_addr via printk extended format specifier %pM instead
of custom code.

Use memcpy to set the address to dev->dev_addr in set_mac_address,
instead of mxing it up in a for loop with printing a debug msg.

Check also if the given address is valid.

No one uses them anymore, they should be using the safer
usb_serial_register_drivers() and usb_serial_deregister_drivers()
functions instead.

Thanks to Alan Stern for writing these functions and porting all
in-kernel users to them.

Subject: [PATCH 3083/6423] USB: qcserial: don't grab QMI port on Gobi 1000

Gobi 1000 devices have a different port layout, which wasn't respected
by the current driver, and thus it grabbed the QMI/net port.  In the
near future we'll be attaching another driver to the QMI/net port for
these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver
doesn't claim them.  This patch also prevents qcserial from binding to
interfaces 0 and 1 on 1K devices because those interfaces do not
respond.

Subject: [PATCH 3084/6423] x86: Fix the NMI nesting comments

Some of the comments for the nesting NMI algorithm were stale and
had some references to some prototypes that were first tried.

I also updated the comments to be a little easier to understand
the flow of the code. It definitely needs the documentation.

Subject: [PATCH 3085/6423] cdc-wdm: Fix more races on the read path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We must not allow the input buffer length to change while we're
shuffling the buffer contents.  We also mustn't clear the WDM_READ
flag after more data might have arrived.  Therefore move both of these
into the spinlocked region at the bottom of wdm_read().

When reading desc->length without holding the iuspin lock, use
ACCESS_ONCE() to ensure the compiler doesn't re-read it with
inconsistent results.

so this driver seems redundant now.

Subject: [PATCH 3089/6423] USB: allow users to run setserial with cdc-acm

We had a user report that running setserial on /dev/ttyACM0 didn't work.
He pointed at an old patch by Oliver Neukum from 2008 that never went anywhere..
http://permalink.gmane.org/gmane.linux.usb.general/9236

I made some minor changes to get it to apply again, and got the user to retest on 3.1,
and he reported it worked for him. https://bugzilla.redhat.com/show_bug.cgi?id=787607

The diff below is against 3.3rc. The only difference between this and
the version the user tested is the removal of the if (!ACM_READY) test
Havard removed ACM_READY in 99823f457d5994b3bd3775515578c8bfacc64b04
I'm unclear if there's need for a different test in its place.

Subject: [PATCH 3094/6423] i2c: Support for Netlogic XLR/XLS I2C controller.

Add support for the intergrated I2C controller on Netlogic
XLR/XLS MIPS SoC.

The changes are to add a new file i2c/buses/i2c-xlr.c, containing the
i2c bus implementation, and to update i2c/buses/{Kconfig,Makefile} to
add the CONFIG_I2C_XLR option.

Subject: [PATCH 3097/6423] usb: Fix build error due to dma_mask is not at
 pdev_archdata at ARM

When build i.mx platform with imx_v6_v7_defconfig, and after adding
USB Gadget support, it has below build error:

CC      drivers/usb/host/fsl-mph-dr-of.o
drivers/usb/host/fsl-mph-dr-of.c: In function 'fsl_usb2_device_register':
drivers/usb/host/fsl-mph-dr-of.c:97: error: 'struct pdev_archdata'
has no member named 'dma_mask'

It has discussed at: http://www.spinics.net/lists/linux-usb/msg57302.html

For PowerPC, there is dma_mask at struct pdev_archdata, but there is
no dma_mask at struct pdev_archdata for ARM. The pdev_archdata is
related to specific platform, it should NOT be accessed by
cross platform drivers, like USB.

The code for pdev_archdata should be useless, as for PowerPC,
it has already gotten the value for pdev->dev.dma_mask at function
arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.

Subject: [PATCH 3099/6423] USB: ums_realtek: do not use stack memory for DMA
 in __do_config_autodelink

__do_config_autodelink passes the data variable to the transport function.
If the calling functions pass a stack variable, this will eventually trigger
a DMA-API debug backtrace for mapping stack memory in the DMA buffer.  Fix
this by calling kmemdup for the passed data instead.

Subject: [PATCH 3106/6423] serial: samsung: fix s3c2442 platform data

Without that fix machines having a s3c2442 CPU have something
  like that in dmesg:
    samsung-uart s3c2440-uart.0: could not find driver data
    samsung-uart s3c2440-uart.1: could not find driver data
    samsung-uart s3c2440-uart.2: could not find driver data
  And serial is never initialized.

The previous log was obtained trough early printk on the gta02
  machine.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

In DMA-operated uart, I found that rx data can be taken by the UART
interrupts during the DMA irq handler. pl011_int is occurred just
before it goes inside spin_lock_irq. When it returns to the callback,
DMA buffer already has been flushed. Then, pl011_dma_rx_chars gets
invalid data. So I add check for the residue as the patch bellow.

Subject: [PATCH 3110/6423] vt: lock the accent table

First step to debletcherising the vt console layer - pick a victim and fix
the locking

This is a nice simple object with its own rules so lets pick it out for
treatment. The user of the table already has a lock so we will also use the
same lock for updates.

Subject: [PATCH 3112/6423] tipc: Introduce node signature field in neighbor
 discovery message

Adds support for the new "node signature" in neighbor discovery messages,
which is a 16 bit identifier chosen randomly when TIPC is initialized.
This field makes it possible for nodes receiving a neighbor discovery
message to detect if multiple neighboring nodes are using the same network
address (i.e. <Z.C.N>), even when the messages are arriving on different
interfaces.

This first phase of node signature support creates the signature,
incorporates it into outgoing neighbor discovery messages, and tracks
the signature used by valid neighbors. An upcoming patch builds on this
foundation to implement the improved duplicate neighbor detection checking.

Subject: [PATCH 3113/6423] tipc: Detect duplicate nodes using different
 network interfaces

Utilizes the new "node signature" field in neighbor discovery messages
to ensure that all links TIPC associates with a given <Z.C.N> network
address belong to the same neighboring node. (Previously, TIPC could not
tell if link setup requests arriving on different interfaces were from
the same node or from two different nodes that has mistakenly been assigned
the same network address.)

The revised algorithm for detecting a duplicate node considers both the
node signature and the network interface adddress specified in a request
message when deciding how to respond to a link setup request. This prevents
false alarms that might otherwise arise during normal network operation
under the following scenarios:

a) A neighboring node reboots. (The node's signature changes, but the
network interface address remains unchanged.)

b) A neighboring node's network interface is replaced. (The node's signature
remains unchanged, but the network interface address changes.)

c) A neighboring node is completely replaced. (The node's signature and
network interface address both change.)

The algorithm also handles cases in which a node reboots and re-establishes
its links to TIPC (or begins re-establishing those links) before TIPC
detects that it is using a new node signature. In such cases of "delayed
rediscovery" TIPC simply accepts the new signature without disrupting
communication that is already underway over the links.

Thanks to Laser [gotolaser@gmail.com] for his contributions to the
development of this enhancement.

Subject: [PATCH 3114/6423] tipc: Remove duplicate check of message destination
 node

Eliminates a check in the processing of TIPC messages arriving from
off node that ensures the message is destined for this node, since this
check duplicates an earlier check. (The check would be necessary if TIPC
needed to be able to route incoming messages to another node, but the
elimination of multi-cluster support means that this never happens and
all incoming messages are consumed by the receiving node.)

Note: This change involves the elimination of a single "if" statement
with a large "then" clause; consequently, a significant number of lines
end up getting re-indented. In addition, a simple message header access
routine that is no longer referenced is eliminated. However, the only
functional change is the elimination of the single check described above.

Subject: [PATCH 3115/6423] tipc: Simplify enforcement of reserved name type
 prohibition

Streamlines the logic that prevents an application from binding a
reserved TIPC name type to a port by moving the check to the code
that handles a socket bind() operation. This allows internal TIPC
subsystems to bind a reserved name without having to set an atomic
flag to gain permission to use such a name. (This simplification is
now possible due to the elimination of support for TIPC's native API.)

Subject: [PATCH 3116/6423] tipc: Add check to prevent insertion of duplicate
 name table entries

Adds a new check to TIPC's name table logic to reject any attempt to
create a new name publication that is identical to an existing one.
(Such an attempt will never happen under normal circumstances, but
could arise if another network node malfunctions and issues a duplicate
name publication message.)

Subject: [PATCH 3117/6423] tipc: nuke the delimit static inline function.

This "shortform" is actually longer than typing out what it is really
trying to do, and just makes reading the code more difficult, so
lets simply shoot it in the head.

In the case of log.c - the comparison is on a u32, so we can drop the
check for < 0 at the same time.

Subject: [PATCH 3119/6423] tipc: Hide internal details of node table
 implementation

Relocates information about the size of TIPC's node table index and
its associated hash function, since only node subsystem routines need
to have access to this information.

Note that these changes are essentially cosmetic in nature, and have
no impact on the actual operation of TIPC.

Gets rid of two inlined routines that simply call existing sk_buff
manipulation routines, since there is no longer any extra processing
done by the helper routines.

Note that these changes are essentially cosmetic in nature, and have
no impact on the actual operation of TIPC.

Subject: [PATCH 3121/6423] tipc: Remove obsolete comments about routing table
 updates

Eliminates a block of comments that describe how routing table updates
are to be handled. These comments no longer apply following the removal
of TIPC's prototype multi-cluster support.

Note that these changes are essentially cosmetic in nature, and have
no impact on the actual operation of TIPC.

Optimizes processing done when contact with a neighboring node is
established to avoid recording the current state of outgoing broadcast
messages if the neighboring node isn't a valid broadcast link destination,
since this state information isn't needed for such nodes.

Subject: [PATCH 3123/6423] tipc: Revert name table translation optimization

Restores name table translation using a non-zero domain that is
"out of scope", which was broken by an earlier commit
(5d9c54c1e9ececcf7e99c4f014f9bec7ee3a7def). Comments have now been
added to the name table translation routine to make it clear that
there are actually three possible outcomes to a translation request
(found/not found/deferred), rather than just two (found/not found).

Note that a straightforward revert of the earlier commit is not
possible, as other changes to the name table translation logic
have occurred since the incorrect optimization was made.

Subject: [PATCH 3124/6423] tipc: Eliminate obsolete support for "not running"
 mode

Removes all references to TIPC's "not running" mode, since the
removal of support for the native API means that there is no longer
any way to interact with TIPC if it has not been initialized.

The changes made consist of removing mode-based checks that are no
longer needed, along with any associated code lying on non-executable
control paths.

Subject: [PATCH 3125/6423] tipc: Eliminate support for tipc_mode global
 variable

Removes all references to the global variable that records whether
TIPC is running in "single node" mode or "network" mode, since this
information can be easily deduced from the global variable that
records TIPC's network address. (i.e. a non-zero network address
means that TIPC is running in network mode.)

The changes made update most existing mode-based checks to use the
network address global variable. A few checks that are no longer
needed are removed entirely, along with any associated code lying on
non-executable control paths.

Subject: [PATCH 3129/6423] [IA64] hpsim, fix SAL handling in fw-emu

The switch-cases of SAL_FREQ_BASE generate non-relocatable code. The
same as for the ifs one level upper. This causes oopses early in boot
because the kernel jumps to the hell instead of the offset in sal
callback.

So use ifs here for SAL_FREQ_BASE decision too.

Isn't there any compiler directive or settings to solve that cleanly?

Subject: [PATCH 3131/6423] [IA64] hpsim, initialize chip for assigned irqs

Currently, when assign_irq_vector is called and the irq connected in
the simulator, the irq is not ready. request_irq will return ENOSYS
immediately. It is because the irq chip is unset.

Hence set the chip properly to irq_type_hp_sim. And make sure this is
done from both users of simulated interrupts.

Also we have to set handler here, otherwise we end up in
handle_bad_int resulting in spam in logs and no irqs handled. We use
handle_simple_irq as these are SW interrupts that need no ACK or
anything.

Subject: [PATCH 3132/6423] sysfs: Fix memory leak in sysfs_sd_setsecdata().

This patch fixies follwing two memory leak patterns that reported by kmemleak.
sysfs_sd_setsecdata() is called during sys_lsetxattr() operation.
It checks sd->s_iattr is NULL or not. Then if it is NULL, it calls
sysfs_init_inode_attrs() to allocate memory.
That code is this.

iattrs = sd->s_iattr;
if (!iattrs)
                iattrs = sysfs_init_inode_attrs(sd);

The iattrs recieves sysfs_init_inode_attrs()'s result,  but sd->s_iattr
doesn't know the address. so it needs to set correct address to
sd->s_iattr to free memory in other function.

Subject: [PATCH 3133/6423] w1_bq27000: remove unnecessary NULL test.

As recent change means that we now dereference 'dev' before testing
for NULL.

That means either the change was wrong, or the test isn't needed.
As this function is only called from one driver (bq27x000_battery) and
it always passed a non-NULL dev, it seems good to assume that the
test isn't needed.

So remove it.

Subject: [PATCH 3136/6423] [IA64] simserial, bail out when request_irq fails

Without this, the code succeeds when the port is opened by root and we
get unwanted interrupts storm on the first key stroke.

Instead of that, tell the user we failed and that we won't continue. I
suppose, the code was copied from the serial layer where we may want
to change the irq number, so we must allow open even of the failing
port. This is not the case for this driver at all.

Subject: [PATCH 3137/6423] PCI: Add class support in quirk handling

Recently added support to allow quirks to report duration also make the
boot log very crowded when initcall_debug is specified.

One thing we can to do mitigate this is to not call quirks unnecessarily
by adding a new quirk declaration macro that takes a class argument.

The new macro takes a class value and a class shift value (since it can
vary) so that quirks will be limited to certain device classes, greatly
reducing the number we call on every PCI device addition.

-v2: fix v1 that left over of sparated patch.
-v3: according to Jesse, change cls to class, cls_shift, to class_shift.

Subject: [PATCH 3151/6423] e1000e: cleanup: rename e1000e_id_led_init() and
 call as function pointer

Rename e1000e_id_led_init() to e1000e_id_led_init_generic() to signify the
function is used for more than one MAC-family type.  For the ich8lan MAC
family, some MACs use the generic function and others use the function
e1000_id_led_init_pchlan().  In all cases where e1000e_id_led_init() was
called directly, change to call the function pointer to be consistent with
the driver design.

Rename e1000e_setup_link() to e1000e_setup_link_generic() to signify the
function is used for more than one MAC-family type.  The 82571-family has
a custom setup_link function which also calls the generic function.  The
ich8lan-family has a custom function which should just be called via the
function pointer.  The 80003es2lan-family just uses the generic function.

Rename e1000e_reload_nvm() to e1000e_reload_nvm_generic() to signify the
function is used for more than one MAC-family type, and set and use it as a
MAC ops function pointer to be consistent with the driver design.

Subject: [PATCH 3163/6423] crypto: twofish-x86_64-3way - use
 crypto_[un]register_algs

Combine all crypto_alg to be registered and use new crypto_[un]register_algs
functions. Simplifies init/exit code and reduce object size.

Subject: [PATCH 3169/6423] xfs: only take the ILOCK in xfs_reclaim_inode()

At the end of xfs_reclaim_inode(), the inode is locked in order to
we wait for a possible concurrent lookup to complete before the
inode is freed.  This synchronization step was taking both the ILOCK
and the IOLOCK, but the latter was causing lockdep to produce
reports of the possibility of deadlock.

It turns out that there's no need to acquire the IOLOCK at this
point anyway.  It may have been required in some earlier version of
the code, but there should be no need to take the IOLOCK in
xfs_iget(), so there's no (longer) any need to get it here for
synchronization.  Add an assertion in xfs_iget() as a reminder
of this assumption.

Dave Chinner diagnosed this on IRC, and Christoph Hellwig suggested
no longer including the IOLOCK.  I just put together the patch.

Subject: [PATCH 3170/6423] target: replace various cmd flags with a transport
 state

Replace various atomic_ts used as flags in struct se_cmd with a single
transport_state bitmap that requires t_state_lock to be held for modifications.

In the target core that assumption generally is true, but some recently added
code in the SRP target had to grow new lock calls.  I can't say I like the way
how it messes with the command state directly, but let's leave that for later.

(Re-add missing ib_srpt.c changes that nab dropped..)

Subject: [PATCH 3171/6423] target: remove the transport_lun_active field in
 struct se_cmd

There is no reason to have a flag telling if a command is on the per-lun list,
we can simply do a list_empty check before removing it as long as we're careful
to always use list_del_init.

Subject: [PATCH 3172/6423] target: remove the unused struct iblock_hba

There is no reason to allocate a struct just to store the host number for
a debug printk in the detach path.  I've simply removed the verbose
debugging given that the calling code thinks the number passed in is
something different from a host ID anyway.

Subject: [PATCH 3173/6423] target: increase iblock task sizes

There is no real limit for task sizes in the iblock driver given that we
can chain bios.  Increase the maximum size to UINT_MAX, and change the
code to submit bios in a smaller batch size to avoid deadlocks when
having more bios in flight than the pool supports.  Also increase the
pool size to always allow multiple tasks to be in flight.

I also had to change the task refcounting to include one reference for
the submission task, which is a standard practice in this kind of code
in Linux (e.g. XFS I/O submission).  This was wrong before, but couldn't
be hit easily.

Subject: [PATCH 3174/6423] target: Use LIST_HEAD()/DEFINE_MUTEX() for static
 objects

Instead of

   static struct list_head foo;
   static struct mutex bar;

   ...

   INIT_LIST_HEAD(&foo);
   mutex_init(&bar);

just do

   static LIST_HEAD(foo);
   static DEFINE_MUTEX(bar);

Also remove some superfluous struct list_head and spinlock_t
initialization calls where the variables are already defined using
macros that initialize them.

This saves a decent amount of compiled code too:

    add/remove: 0/0 grow/shrink: 0/3 up/down: 0/-178 (-178)

This allows us to use scsilun_to_int without an ugly cast.

Fix up places that use scsilun_to_int on fcp->fc_lun accordingly.

In fc target, this leaves ft_cmd.lun unused, so remove it.

Subject: [PATCH 3183/6423] target: Add SCF_SCSI_TMR_CDB usage and drop
 se_tmr_req_cache

Change the test for if a cmd is a tmr request to checking if
SCF_SCSI_TMR_CDB (a new flag) is set in cmd->se_cmd_flags.

Also remove se_tmr_req_cache usage in favor of kzalloc usage,
and make core_tmr_alloc_req() return int + setup se_cmd->se_tmr_req
directly and fix up various fabric module usages

Subject: [PATCH 3189/6423] tcm_loop: kill tcm_loop_allocate_core_cmd

This function makes little sense as a separate abstraction as it's deeply
interwinded with the control flow of its only caller.  Merged it into
tcm_loop_queuecommand after factoring out a helper to convert the task
attribute representation.

Subject: [PATCH 3192/6423] target: Cleanup transport_kunmap_data_sg()

This code isn't broken per se, but it's scary to look at! It looks like
in the t_data_nents==1 case we're doing both a kunmap and a vunmap,
what's saving us is that t_data_vmap in this case is 0, so vunmap
doesn't do anything.

Return after kunmap, so the handling of the three cases does not overlap.

Subject: [PATCH 3193/6423] target: Export transport_generic_request_failure
 symbol

transport_generic_request_failure() is a wrapper around calling
transport_send_check_condition_and_sense() that is required once
an se_cmd->cmd_kref has been obtained via target_submit_cmd() ->
target_get_sess_cmd().

tcm_qla2xxx currently requires this, and since it's necessary for
other callers using target_submit_cmd() make it exportable now.

Subject: [PATCH 3196/6423] target: Add TMR_ABORT_TASK task management support

This patch adds initial support for TMR_ABORT_TASK ops for se_cmd
descriptors using se_sess->sess_cmd_list and se_cmd->cmd_kref counting.

It will perform an explict abort for all outstanding se_cmd ops based
upon tmr->ref_task_tag that have not been set CMD_T_COMPLETE.
It will cancel se_cmd->work and wait for backing I/O to complete before
attempting to send SAM_STAT_TASK_ABORTED and perform
target_put_sess_cmd() to release the referenced descriptor.

It also adds a CMD_T_ABORTED check into transport_complete_task() to
catch the completion from backend I/O that has been aborted, and
updates transport_wait_for_tasks() to allow CMD_T_ABORTED usage with
core_tmr_abort_task() context.

Subject: [PATCH 3197/6423] target: Fix up handling of short INQUIRY buffers

If the initiator sends us an INQUIRY command with an allocation length
that's shorter than what we want to return, we're simply supposed to
truncate our response and return what the initiator gave us space for,
without signaling any error.  Current target code has various tests that
don't fill out the full response if the buffer is too short and
sometimes return errors incorrectly.

Fix this up by allocating a bounce buffer for INQUIRY responses if we
need to, ie if we have cmd->data_length too small as well as
SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC set in cmd->se_cmd_flags -- for most
fabrics, we always allocate at least a full page, but for tcm_loop we
may have a small buffer coming directly from the SCSI stack.

This lets us delete a lot of cmd->data_length checking, and also makes
our INQUIRY handling correct per SPC in a lot more cases.

Subject: [PATCH 3198/6423] target: Set peripheral device type consistently in
 INQUIRY response

Current code sets the peripheral device type to 0x3f == "not present
unknown" for virtual LUN 0 for standard INQUIRY commands, but leaves it
as 0 == "connected direct access block" for VPD INQUIRY commands.  This
is just because the check for LUN 0 only happens in some code paths.

Make our peripheral device type consistent by moving the LUN 0 check
into the common emulate_inquiry() code.

Subject: [PATCH 3199/6423] target: Don't set WBUS16 or SYNC bits in INQUIRY
 response

SPC-4 says about the WBUS16 and SYNC bits:

    The meanings of these fields are specific to SPI-5 (see 6.4.3).
    For SCSI transport protocols other than the SCSI Parallel
    Interface, these fields are reserved.

We don't have a SPI fabric module, so we should never set these bits.
(The comment was misleading, since it only mentioned Sync but the
actual code set WBUS16 too).

Subject: [PATCH 3200/6423] target: Untangle front-end and back-end meanings of
 max_sectors attribute

se_dev_attrib.max_sectors currently has two independent meanings:

 - It is reported in the block limits VPD page as the maximum transfer
   length, ie the largest IO that the front-end (fabric) can handle.
   Also the target core doesn't enforce this maximum transfer length.

 - It is used to hold the size of the largest IO that the back-end can
   handle, so we know when to split SCSI commands into multiple tasks.

Fix this by adding a new se_dev_attrib.fabric_max_sectors to hold the
maximum transfer length, and checking incoming IOs against that limit.

Subject: [PATCH 3201/6423] tcm_loop: Set residual field for SCSI commands

If the target core signals an over- or under-run, tcm_loop should call
scsi_set_resid() to tell the SCSI midlayer about the residual data length.

The difference can be seen by doing something like

    strace -eioctl sg_raw -r 1024 /dev/sda 8 0 0 0 1 0 > /dev/null

and looking at the "resid=" part of the SG_IO ioctl -- after this patch,
the field is correctly reported as 512.

transport_kmap_data_sg can return NULL.  I never saw this trigger, but
returning -ENOMEM seems better than a crash.  Also removes a pointless

Subject: [PATCH 3204/6423] target: Fix off-by-seven in target_report_luns

cdb_offset is always equal to offset - 8, so remove that one.  More
importantly, the existing code only worked correct if
se_cmd->data_length is a multiple of 8.  Pass in a length of, say, 9 and
we will happily overwrite 7 bytes of "unallocated" memory.

Now, afaics this bug is currently harmless, as allocations will
implicitly be padded to multiples of 8 bytes.  But depending on such a
fact wouldn't qualify as sound engineering practice.

Subject: [PATCH 3213/6423] IB/qib: Add logic for affinity hint

Call irq_set_affinity_hint() to give userspace programs such as
irqbalance the information to be able to distribute qib interrupts
appropriately.

The logic allocates all non-receive interrupts to the first CPU local
to the HCA.  Receive interrupts are allocated round robin starting
with the second CPU local to the HCA with potential wrap back to the
second CPU.

This patch also adds a refinement to the name registered for MSI-X
interrupts so that user level scripts can determine the device
associated with the IRQs when there are multiple HCAs with a
potentially different set of local CPUs.

changing zero to 0xffff.

This causes OpenSM to log excessive warning messages.

Subject: [PATCH 3224/6423] mlx4: Enforce device max FMR maps in FMR alloc

ConnectX devices have a limit on the number of mappings that can be
done on an FMR before having to call sync_tpt.  The current
mlx4_ib driver reports the limit correctly in max_map_per_fmr in
.query_device(), but mlx4_core doesn't check it when actually
allocating FMRs.

Add a max_fmr_maps field to struct mlx4_caps and enforce this maximum
value on FMR allocations.

Subject: [PATCH 3226/6423] netlink: add netlink_dump_control structure for
 netlink_dump_start()

Davem considers that the argument list of this interface is getting
out of control. This patch tries to address this issue following
his proposal:

struct netlink_dump_control c = { .dump = dump, .done = done, ... };

netlink_dump_start(..., &c);

Suggested by David S. Miller.

Subject: [PATCH 3227/6423] netlink: allow to pass data pointer to
 netlink_dump_start() callback

This patch allows you to pass a data pointer that can be
accessed from the dump callback.

Netfilter is going to use this patch to provide filtered dumps
to user-space. This is specifically interesting in ctnetlink that
may handle lots of conntrack entries. We can save precious
cycles by skipping the conversion to TLV format of conntrack
entries that are not interesting for user-space.

More specifically, ctnetlink will include one operation to allow
to filter the dumping of conntrack entries by ctmark values.

Subject: [PATCH 3228/6423] netfilter: ctnetlink: support kernel-space dump
 filtering by ctmark

This patch adds CTA_MARK_MASK which, together with CTA_MARK, allows
you to selectively send conntrack entries to user-space by
returning those that match mark & mask.

With this, we can save cycles in the building and the parsing of
the entries that may be later on filtered out in user-space by using
the ctmark & mask.

Subject: [PATCH 3229/6423] mlx4_en: dont change mac_header on xmit

A driver xmit function is not allowed to change skb without special
care.

mlx4_en_xmit() should not call skb_reset_mac_header() and instead should
use skb->data to access ethernet header.

This removes a dumb test : if (ethh && ethh->h_dest)

Also remove this slow mlx4_en_mac_to_u64() call, we can use
get_unaligned() to get faster code.

Subject: [PATCH 3230/6423] x86_64: Record stack pointer before task execution
 begins

task->thread.usersp is unusable immediately after a binary is exec()'d
until it undergoes a context switch cycle. The start_thread() function
called during execve() saves the stack pointer into pt_regs and into
old_rsp, but fails to record it into task->thread.usersp.

Because of this, KSTK_ESP(task) returns an incorrect value for a
64-bit program until the task is switched out and back in since
switch_to swaps %rsp values in and out into task->thread.usersp.

Subject: [PATCH 3232/6423] irq_domain: Centralize definition of

Several architectures define their own empty irq_dispose_mapping().  Since
the irq_domain code is centralized now, there is little need to do so.  This
patch removes them and creates a new empty copy when !CONFIG_IRQ_DOMAIN is
selected.

The patch also means that IRQ_DOMAIN becomes selectable on all architectures.

Subject: [PATCH 3233/6423] devicetree: Add empty of_platform_populate() for
 !CONFIG_OF_ADDRESS (sparc)

Sparc has its own helpers for translating address ranges when the device
tree is parsed at boot time, and it isn't able to use of_platform_populate().
However, there are some device drivers that want to use that function on
other DT enabled platforms (ie. TWL4030).  This patch adds an empty
of_platform_populate() implementation that returns an error when
CONFIG_OF_ADDRESS is not selected.

Subject: [PATCH 3234/6423] mfd: twl-core: Add IRQ_DOMAIN dependency

TWL4030 depends on IRQ_DOMAIN support, so this patch selects it in Kconfig.
It used to be that CONFIG_IRQ_DOMAIN must only be selected by the architecture,
but recent cleanups have fixed it so that it is safe to select from anywhere.

Subject: [PATCH 3235/6423] powerpc/mpic: Fix allocation of reverse-map for
 multi-ISU mpics

When using a multi-ISU MPIC, we can interrupts up to
isu_size * MPIC_MAX_ISU, not just isu_size, so allocate
the right size reverse map.

Without this, the code will constantly fallback to
a linear search.

Lockdep occasionally complains with the message:
INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected

This is caused by calling videobuf_dma_unmap() under spin_lock_irq(). To
fix the warning, we drop the lock before unmapping and freeing the
buffer.

Subject: [PATCH 3241/6423] carma-fpga: fix race between data dumping and DMA
 callback

When the system is under heavy load, we occasionally saw a problem where
the system would get a legitimate interrupt when they should be
disabled.

This was caused by the data_dma_cb() DMA callback unconditionally
re-enabling FPGA interrupts even when data dumping is disabled. When
data dumping was re-enabled, the irq handler would fire while a DMA was
in progress. The "BUG_ON(priv->inflight != NULL);" during the second
invocation of the DMA callback caused the system to crash.

To fix the issue, the priv->enabled boolean is moved under the
protection of the priv->lock spinlock. The DMA callback checks the
boolean to know whether to re-enable FPGA interrupts before it returns.

Now that it is fixed, the driver keeps FPGA interrupts disabled when it
expects that they are disabled, fixing the bug.

Commit eab9e6137f23 ("x86-64: Fix CFI data for interrupt frames")
introduced a DW_CFA_def_cfa_expression in the SAVE_ARGS_IRQ
macro. To later define the CFA using a simple register+offset
rule both register and offset need to be supplied. Just using
CFI_DEF_CFA_REGISTER leaves the offset undefined. So use
CFI_DEF_CFA with reg+off explicitly at the end of
common_interrupt.

From b96d3b08365f5a9603f50f3aadca6012f7eaffa1 Mon Sep 17 00:00:00 2001
From: Heikki Krogerus <heikki.krogerus@linux.intel.com>
Date: Mon, 13 Feb 2012 13:24:18 +0200
Subject: [PATCH 3250/6423] usb: Convert all users to new usb_phy

Use the new usb_phy_* functions with transceiver
operations instead of the old otg functions.

Includes fixes from Sascha Hauer.

Subject: [PATCH 3252/6423] usb: otg: Convert all users to pass struct usb_otg
 for OTG functions

This changes the otg functions so that they receive struct
otg instead of struct usb_phy as parameter and
converts all users of these functions to pass the otg member
of their usb_phy.

Includes fixes to IMX code from Sascha Hauer.

From d0ff7383a3164adff7072719717d574436ec1677 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3253/6423] ath6kl: Add unicast mgmt frame buffering

PS buffering of unicast Action frames that are sent in a context
of a BSS. In AP mode when the recepient station goes to powersave
and PS_POLL flag is not set, we would buffer the frames. Send out
unicast mgmt bufferred frame when PS_POLL is received.

This fixes a bug in P2P GO behavior when sending a GO Discoverability
Request to a client that is in sleep mode.

kvalo: indentation fixes

Subject: [PATCH 3271/6423] drm/i915: Only bump refcnt on objects scheduled for
 eviction

Incrementing the reference count on all objects walked when searching
for space in the aperture is a non-neglible amount of overhead. In fact,
we only need to hold on to a reference for objects that we will evict,
so we can therefore delay the referencing until we find a suitable hole
and only add those objects that fall inside.

Subject: [PATCH 3274/6423] drm/i915: use the new hdmi_force_audio enum more

While fixing up a merge conflict with drm-next I've noticed that we
use the same audio drm connector property also for dp and sdvo
outputs.

So put the new enum to some good use and convert these paths, too. The
HDMI_AUDIO_ prefix is a bit a misnomer. But at least for sdvo it makes
sense (and you can also connect a hdmi monitor with a dp->hdmi cable),
so I've decided to stick with it.

Subject: [PATCH 3276/6423] drm/i915: error_buffer->ring should be signed

gcc seems to get uber-anal recently about these things.

Clarification from Dan Carpenter:

"Sorry, I should have said that it's not a gcc warning, it's a smatch
thing.  But also it's not uber-anal.  It's the exact level of anality
which is required to make the == -1 test work.  You can compare
unsigned int and longs to -1 and it works but for smaller types it
doesn't."

Subject: [PATCH 3277/6423] ath6kl: assign Tx packet drop threshold per
 endpoint based on AC priority

Tx packets will begin to drop when there are multiple traffic priorities
and the current traffic is not the highest priority and the remaining
cookies drop below a certain number, which is fixed for all AC. It is
possilbe that lower priority AC have more traffic which will consume
more cookies and lock out higher priority AC from having any. Assign
each endpoint (AC) with a different Tx-packet-drop threshold so lower
priority AC is more likely to drop packets and the cookies become more
available to higher priority AC.

Commit 71eeba16 ("IB: Add new InfiniBand link speeds") introduced a bug
where eg the rate for IB 4X SDR links iss displayed as "8.5 Gb/sec"
instead of "10 Gb/sec" as it used to be.  Fix that.

Subject: [PATCH 3282/6423] IB/srp: Consolidate repetitive sysfs code

Remove sysfs attributes before removing a target instead of testing
the target state in every sysfs attribute callback method. Note: it is
safe to invoke a sysfs attribute removal method like
device_remove_file() twice on the same attribute.

Subject: [PATCH 3285/6423] SUNRPC: check RPC inode's pipe reference before
 dereferencing

There are 2 tightly bound objects: pipe data (created for kernel needs, has
reference to dentry, which depends on PipeFS mount/umount) and PipeFS
dentry/inode pair (created on mount for user-space needs). They both
independently may have or have not a valid reference to each other.
This means, that we have to make sure, that pipe->dentry reference is valid on
upcalls, and dentry->pipe reference is valid on downcalls. The latter check is
absent - my fault.
IOW, PipeFS dentry can be opened by some process (rpc.idmapd for example), but
it's pipe data can belong to NFS mount, which was unmounted already and thus
pipe data was destroyed.
To fix this, pipe reference have to be set to NULL on rpc_unlink() and checked
on PipeFS file operations instead of pipe->dentry check.

Note: PipeFS "poll" file operation will be updated in next patch, because it's
logic is more complicated.

Subject: [PATCH 3286/6423] SUNRPC: move waitq from RPC pipe to RPC inode

Currently, wait queue, used for polling of RPC pipe changes from user-space,
is a part of RPC pipe. But the pipe data itself can be released on NFS umount
prior to dentry-inode pair, connected to it (is case of this pair is open by
some process).
This is not a problem for almost all pipe users, because all PipeFS file
operations checks pipe reference prior to using it.
Except evenfd. This thing registers itself with "poll" file operation and thus
has a reference to pipe wait queue. This leads to oopses on destroying eventfd
after NFS umount (like rpc_idmapd do) since not pipe data left to the point
already.
The solution is to wait queue from pipe data to internal RPC inode data. This
looks more logical, because this wiat queue used only for user-space processes,
which already holds inode reference.

Note: upcalls have to get pipe->dentry prior to dereferecing wait queue to make
sure, that mount point won't disappear from underneath us.

From 14fec8d9baffc026beaffa2ee9e911df9d1d4ad2 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3288/6423] ath9k_hw: remove duplicate initvals

Comparing SHA1 checksums of the initval tables has shown that there are many
tables that are 100% identical.

iniBank{0,1,2,3,7} and iniBB_RfGain are shared by AR5416, AR913x, AR9160
iniBank6 is shared between AR5416 and AR9160
iniBank6TPC is shared between AR913x and AR9160

iniPcieSerdes is the same for all AR9002 based devices

The CCK FIR coefficients are shared between AR9271 and AR9287

Getting rid of those duplicates saves about 7.5k uncompressed (on MIPS).

For AR9003 and later there are some duplicates as well, but I've decided to
leave them in for now, as the initvals for those chips are still actively
maintained by QCA.

Subject: [PATCH 3290/6423] ath9k: Merge wiphy and misc debugfs files

This patch merges the 'wiphy' and 'misc' debugfs files
and consolidates the information.

Information about the current channel and other HT parameters
can be obtained from both mac80211 and iw. Remove such
redundant data.

The reset statistics have been removed, they will be re-added in
a subsequent patch (in a new debugfs file).

Subject: [PATCH 3295/6423] ath9k: Initialize NF values properly

Using AR_SREV_* macros for setting up the chip-specific NF
values will make adding support for new chips hard. Use separate
macros for each chip. Currently, AR9462 has the same value for
all NF limits.

Subject: [PATCH 3306/6423] mac80211: fix associated vs. idle race

Eliad reports that if a scan finishes in the
middle of processing associated (however it
happens), the interface can go idle. This is
because we set assoc_data to NULL before we
set associated. Change the order so any idle
check will find either one of them.

Doing this requires duplicating the TX sync
processing, but I already have a patch to
delete that completely and will submit that
as soon as my driver changes to no longer
require it are submitted.

Subject: [PATCH 3308/6423] ath9k: Cleanup MCI init/deinit routines

This patch simplifies the buffer allocation functions
for MCI and removes unneeded memset calls. Also, a couple
of unused variables are removed and a memory leak in DMA
allocation is fixed.

Subject: [PATCH 3315/6423] ath9k: Initialize BTCOEX scheme using a helper

Setting up the required scheme can be done as part of the
BTCOEX initialization path and it doesn't belong in
ath9k_hw_fill_cap_info() anyway.

Subject: [PATCH 3320/6423] ath9k_hw: Cleanup MCI bits from hw.h

This patch moves all the MCI-specific declarations that have been
dumped unceremoniously in hw.h to ar9003_mci.h

Subject: [PATCH 3322/6423] ath9k_hw: Use CONFIG_ATH9K_BTCOEX_SUPPORT

Make use of CONFIG_ATH9K_BTCOEX_SUPPORT in ath9k_hw
to provide a clean way of compilation without BTCOEX
support.

Subject: [PATCH 3337/6423] mac80211: fix auth/assoc data & timer leak

When removing an interface while it is in the
process of authenticating or associating, we
leak the auth_data or assoc_data, and leave
the timer pending. The timer then crashes the
system when it fires as its data is gone.

Fix this by explicitly deleting all the data
when the interface is removed. This uncovered
another bug -- this problem should have been
detected by the sta_info_flush() warning but
that function doesn't ever return non-zero,
I'll fix that in a separate patch.

Subject: [PATCH 3338/6423] mac80211: fix sta_info_flush() return value

The comment for sta_info_flush() states
"Returns the number of removed STA entries"
but that isn't actually true. Consequently,
the warning when a station is still around
on interface removal can never trigger and
this delayed finding the timer issue the
previous patch fixed. Fix the return value
here to make that warning useful again.

Subject: [PATCH 3350/6423] AppArmor: Fix dropping of allowed operations that
 are force audited

The audit permission flag, that specifies an audit message should be
provided when an operation is allowed, was being ignored in some cases.

This is because the auto audit mode (which determines the audit mode from
system flags) was incorrectly assigned the same value as audit mode. The
shared value would result in messages that should be audited going through
a second evaluation as to whether they should be audited based on the
auto audit, resulting in some messages being dropped.

Subject: [PATCH 3351/6423] AppArmor: Fix underflow in xindex calculation

If the xindex value stored in the accept tables is 0, the extraction of
that value will result in an underflow (0 - 4).

In properly compiled policy this should not happen for file rules but
it may be possible for other rule types in the future.

To exploit this underflow a user would have to be able to load a corrupt
policy, which requires CAP_MAC_ADMIN, overwrite system policy in kernel
memory or know of a compiler error resulting in the flaw being present
for loaded policy (no such flaw is known at this time).

The mapping of AA_MAY_META_READ for the allow mask was also being mapped
to the audit and quiet masks. This would result in some operations being
audited when the should not.

This flaw was hidden by the previous audit bug which would drop some
messages that where supposed to be audited.

Subject: [PATCH 3353/6423] AppArmor: Fix the error case for chroot relative
 path name lookup

When a chroot relative pathname lookup fails it is falling through to
do a d_absolute_path lookup.  This is incorrect as d_absolute_path should
only be used to lookup names for namespace absolute paths.

From 210647af897af8ef2d00828aa2a6b1b42206aae6 Mon Sep 17 00:00:00 2001
From: Yinghai Lu <yinghai@kernel.org>
Date: Sat, 25 Feb 2012 13:54:20 -0800
Subject: [PATCH 3354/6423] PCI: Rename pci_remove_bus_device to
 pci_stop_and_remove_bus_device

The old pci_remove_bus_device actually did stop and remove.

Make the name reflect that to reduce confusion.

This patch is done by sed scripts and changes back some incorrect
__pci_remove_bus_device changes.

Subject: [PATCH 3355/6423] PCI: Rename pci_remove_behind_bridge to
 pci_stop_and_remove_behind_bridge

The old pci_remove_behind_bridge actually do stop and remove.

Make the name reflect that to reduce confusion.

Subject: [PATCH 3356/6423] PCI: export __pci_remove_bus_device

Don't switch to pci_remove_bus_device yet, keep the __ prefix for now
(the behavior is still the same: remove without stopping first).

This allows other out of tree users or pending patches to get notified
from compiler warning.

Subject: [PATCH 3361/6423] iwlwifi: move content of iwl_probe to post fetch_fw

This will allow to have different behavior depending on the fw.
Different fw APIs require completely different implementation
of the mac80211 APIs. Each of these implementations is called an
op_mode.

The current op_mode is called DVM which states for dual virtual MAC.

Subject: [PATCH 3362/6423] iwlwifi: move uCode flags handling to op_mode

The uCode flags modification is op_mode dependent
since the P2P config is an op-mode config.

This also fixes P2P enabling: due to the uCode
loading code shuffle moving the SKU check before
the EEPROM was read it was always false and would
always disable PAN/P2P.

Subject: [PATCH 3363/6423] iwlwifi: introducing the drv object's flows

Fetch the fw and spawn the op_mode. The op_mode that we need
to fetch is determined from the fw file.
Since the fw is fetched very early in the init flow, we can
determine what op_mode to spawn.

+
+ * The init flow wrt to the drv component looks like this:
+ * 1) The bus specific component is called from module_init
+ * 2) The bus specific component registers the bus driver
+ * 3) The bus driver calls the probe function
+ * 4) The bus specific component configures the bus
+ * 5) The bus specific component calls to the drv bus agnostic part
+ *    (iwl_drv_start)
+ * 6) iwl_drv_start fetches the fw ASYNC, iwl_ucode_callback
+ * 7) iwl_ucode_callback parses the fw file
+ * 8) iwl_ucode_callback starts the wifi implementation to matches the fw

Subject: [PATCH 3365/6423] iwlwifi: rename iwl_remove to iwl_op_mode_dvm_stop

iwl_remove stops the wifi flows, so rename.
Moreover, we can possibly stop the wifi flows even if the driver
is statically compiled in the kernel, so remove the __devexit pragma.

Subject: [PATCH 3366/6423] iwlwifi: virtualize the op_mode

Define the op_mode as an interface with its ops. All the functions
of the op_mode are "private", but its ops is made public in
iwl-op-mode.h.
The drv object starts the op_mode by using the start function in the
public ops.

Subject: [PATCH 3368/6423] iwlwifi: virtualize op_mode's free skb

This handler allows the transport layer to free an skb from the
op_mode. This can happen when the driver is stopped while Tx
packets are pending in the transport layer.

-/**
- * DOC: Bus layer - role and goal
- *
- * iwl-bus.h defines the API to the bus layer of the iwlwifi driver.
- * The bus layer is responsible for doing very basic bus operations that are
- * listed in the iwl_bus_ops structure.
- * The bus layer registers to the bus driver, advertises the supported HW and
- * gets notifications about enumeration, suspend, resume.
- * For the moment, the bus layer is not a linux kernel module as itself, and
- * the module_init function of the driver must call the bus specific
- * registration functions. These functions are listed at the end of this file.
- * For the moment, there is only one implementation of this interface: PCI-e.
- * This implementation is iwl-pci.c
- */
-
-/**
- * DOC: encapsulation and type safety
- *
- * The iwl_bus describes the data that is shared amongst all the bus layer
- * implementations. This data is visible to other layers. Data in the bus
- * specific area is not visible outside the bus specific implementation.
- * iwl_bus holds a pointer to iwl_shared which holds pointer to all the other
- * layers of the driver (iwl_priv, iwl_trans). In fact, this is the way to go
- * when the transport layer needs to call a function of another layer.
- *
- * In order to achieve encapsulation, iwl_priv cannot be dereferenced from the
- * bus layer. Type safety is still kept since functions that gets iwl_priv gets
- * a typed pointer (as opposed to void *).
- */
-
-/**
- * DOC: probe flow
- *
- * The module_init calls the bus specific registration function. The
- * registration to the bus layer will trigger an enumeration of the bus which
- * will call the bus specific probe function.
- * The first thing this function must do is to allocate the memory needed by
- * iwl_bus + the bus_specific data.
- * Once the bus specific probe function has configured the hardware, it
- * chooses the appropriate transport layer and calls iwl_probe that will run
- * the bus independent probe flow.
- *
- * Note: The bus specific code must set the following data in iwl_bus before it
- *       calls iwl_probe:
- *	* bus->dev
- *	* bus->irq
- *	* bus->ops

Subject: [PATCH 3386/6423] Bluetooth: Remove redundant read_host_features
 commands

Previously the write_le_enable would trigger a read_host_features
command but since we have access to the value LE support was set to we
can simply just clear or set the bit in hdev->host_features. This also
removes a second unnecessary read_host_features command from the device
initialization procedure since LE is only enabled after the first
read_host_features command completes.

Subject: [PATCH 3392/6423] ath6kl: Make sure to allocate rx buffers after the
 endpoint connection

Rx buffers should be allocated for control and best effort endpoints only
after the enpoints connection is esablished. But this is done before the
endpoint connection is complete, we don't even the control and BE endpoints
that time. Move the buffer allocation after endpoint connection is over,
after ath6kl_init_hw_start(). Found in review, never seen any real issue
with this.

Subject: [PATCH 3394/6423] ath6kl: Make foreground scan a deterministic one

This makes the device get into scan state as soon as a
scan request is received, instead of blocking the scan
request till the traffic comes down. It is  necessary
for the deterministic foreground scan particularly when
having multiple vif operating where, if the scan is non-
deterministic, scan on one interface will not start
as long as there are traffic on the other interface. This
change passes 50 msec as foreground scan interval to fix this.

Subject: [PATCH 3395/6423] ath6kl: Lower SDIO pad drive strength for hw2.1.1
 board

Without this change, SDIO shuts down due to CRC error during
data communication to the firmware in some of the platform.
for example, scan request issued to the firmware doesn't
return scan completed events and cause the socket interface
to always return -16 (device busy).

SDIO pad drive strength should be reduced for hw2.1.1 board
to avoid such errors.

Subject: [PATCH 3401/6423] [media] MEM2MEM: Add support for eMMa-PrP mem2mem
 operations

i.MX2x SoCs have a PrP which is capable of resizing and format
conversion of video frames. This driver provides support for
resizing and format conversion from YUYV to YUV420.

This operation is of the utmost importance since some of these
SoCs like i.MX27 include an H.264 video codec which only
accepts YUV420 as input.

Subject: [PATCH 3402/6423] [media] MX2: Add platform definitions for eMMa-PrP
 device

eMMa-PrP device included in Freescale i.MX2 chips can also
be used separately to process memory buffers. This patch
provides arch glue code for the driver which provides this
functionality.

This patch adds a new position_fix option value, 4, as a combo mode
to use LPIB for playbacks and POSBUF for captures.  It's the way
recommended by Intel hardware guys.

Subject: [PATCH 3405/6423] wl12xx: set the ELP entry delay to the FW dyn-ps
 timeout

With PSM handled in FW, the checks in wl1271_elp_work() are always true.
Thus during active traffic we constantly enter and exit ELP (many times
per second). As each ELP exit takes ~10ms, this can have an adverse
effect on throughput and interactivity.
Set the ELP timeout to the dyn-ps timeout. This period is longer and
avoids the above problem. It also makes sense to stay out of ELP while
we are awake on the network, to minimize delays in Tx/Rx. The same thing
was done by the mac80211 dynamic-ps mechanism before the FW DPS changes.

Subject: [PATCH 3407/6423] wl12xx: reset link Tx queues when freeing it

Before, the link was first freed (invalidating it in the map), and later
on vif removal, all valid wlvif-related links were reset. Since these
links were already invalid, we failed to reset them.
The bug was made worse by op_stop, which set the tx_queue_count to 0
arbitrarily. This resulted in a negative tx_queue_count in some scenarios.

Fix this by resetting the Tx-queues of a link when freeing it. Add a
WARN_ON and reset all link Tx-queues in op_stop, to avoid a negative
tx_queue_count.

[changed WARN_ON to WARN_ON_ONCE -- Luca]

Subject: [PATCH 3408/6423] wl12xx: avoid starving the system hlid

Re-factor the Tx scheduler so that the system_hlid is taken into account
before restarting an iteration over the wlvifs. Previously this
hlid had a lower priority and would starve if some wlvif had many
packets.
In addition avoid iterating over wlvifs past last_wlvif when performing
the a second pass. If we had packets in those wlvifs they would have
been found earlier.

Align mpc8610_hpcd with p1022_ds on getting codec node by just calling
of_parse_phandle.  The bonus point of doing that is we can save
exporting get_node_by_phandle_name() when we consolidate the common
bits between mpc8610_hpcd and p1022_ds into a module, which can be
shared by more machine drivers added later.

Subject: [PATCH 3418/6423] usb: dwc3: gadget: use generic map/unmap routines

those routines have everything we need to map/unmap
USB requests and it's better to use them.

In order to achieve that, we had to add a simple
change on how we allocate and use our setup buffer;
we cannot allocate it from coherent anymore otherwise
the generic map/unmap routines won't be able to easily
know that the GetStatus request already has a DMA
address.

Date: Fri, 20 Jan 2012 10:38:36 +0000
Subject: [PATCH 3433/6423] GFS2: glock statistics gathering

The stats are divided into two sets: those relating to the
super block and those relating to an individual glock. The
super block stats are done on a per cpu basis in order to
try and reduce the overhead of gathering them. They are also
further divided by glock type.

In the case of both the super block and glock statistics,
the same information is gathered in each case. The super
block statistics are used to provide default values for
most of the glock statistics, so that newly created glocks
should have, as far as possible, a sensible starting point.

The statistics are divided into three pairs of mean and
variance, plus two counters. The mean/variance pairs are
smoothed exponential estimates and the algorithm used is
one which will be very familiar to those used to calculation
of round trip times in network code.

The three pairs of mean/variance measure the following
things:

 1. DLM lock time (non-blocking requests)
 2. DLM lock time (blocking requests)
 3. Inter-request time (again to the DLM)

A non-blocking request is one which will complete right
away, whatever the state of the DLM lock in question. That
currently means any requests when (a) the current state of
the lock is exclusive (b) the requested state is either null
or unlocked or (c) the "try lock" flag is set. A blocking
request covers all the other lock requests.

There are two counters. The first is there primarily to show
how many lock requests have been made, and thus how much data
has gone into the mean/variance calculations. The other counter
is counting queueing of holders at the top layer of the glock
code. Hopefully that number will be a lot larger than the number
of dlm lock requests issued.

So why gather these statistics? There are several reasons
we'd like to get a better idea of these timings:

1. To be able to better set the glock "min hold time"
2. To spot performance issues more easily
3. To improve the algorithm for selecting resource groups for
allocation (to base it on lock wait time, rather than blindly
using a "try lock")
Due to the smoothing action of the updates, a step change in
some input quantity being sampled will only fully be taken
into account after 8 samples (or 4 for the variance) and this
needs to be carefully considered when interpreting the
results.

Knowing both the time it takes a lock request to complete and
the average time between lock requests for a glock means we
can compute the total percentage of the time for which the
node is able to use a glock vs. time that the rest of the
cluster has its share. That will be very useful when setting
the lock min hold time.

The other point to remember is that all times are in
nanoseconds. Great care has been taken to ensure that we
measure exactly the quantities that we want, as accurately
as possible. There are always inaccuracies in any
measuring system, but I hope this is as accurate as we
can reasonably make it.

Subject: [PATCH 3434/6423] GFS2: Move two functions from log.c to lops.c

gfs2_log_get_buf() and gfs2_log_fake_buf() are both used
only in lops.c, so move them next to their callers and they
can then become static.

From: Steven Whitehouse <swhiteho@redhat.com>
Date: Wed, 8 Feb 2012 12:58:32 +0000
Subject: [PATCH 3435/6423] GFS2: FITRIM ioctl support

The FITRIM ioctl provides an alternative way to send discard requests to
the underlying device. Using the discard mount option results in every
freed block generating a discard request to the block device. This can
be slow, since many block devices can only process discard requests of
larger sizes, and also such operations can be time consuming.

Rather than using the discard mount option, FITRIM allows a sweep of the
filesystem on an occasional basis, and also to optionally avoid sending
down discard requests for smaller regions.

In GFS2 FITRIM will work at resource group granularity. There is a flag
for each resource group which keeps track of which resource groups have
been trimmed. This flag is reset whenever a deallocation occurs in the
resource group, and set whenever a successful FITRIM of that resource
group has taken place. This helps to reduce repeated discard requests
for the same block ranges, again improving performance.

Subject: [PATCH 3436/6423] GFS2: Sort the ordered write list

This patch sorts the ordered write list for GFS2 writes.
This increases the throughput for simultaneous writes.
For example, if you have ten processes, all doing:
dd if=/dev/zero of=/mnt/gfs2/fileX
on different files, the throughput will be much better.

Subject: [PATCH 3439/6423] tools/include: Add byteshift headers for endian
 access

There are various hostprogs in the kernel that are rolling their own
implementations of {get,put}_unaligned_le*(). Copy the byteshift
headers from include/linux/unaligned so that they can all use a single
implementation.

This requires changing some of the data types to the userspace
exported ones (u32 -> __u32, etc).

Subject: [PATCH 3442/6423] x86, boot: Restrict CFLAGS for hostprogs

Currently tools/build has access to all the kernel headers in
$(srctree). This is unnecessary and could potentially allow
tools/build to erroneously include kernel headers when it should only
be including userspace-exported headers.

Unfortunately, mkcpustr still needs access to some of the asm kernel
headers, so explicitly special case that hostprog.

Subject: [PATCH 3443/6423] x86, efi: Fix endian issues and unaligned accesses

We may need to convert the endianness of the data we read from/write
to 'buf', so let's use {get,put}_unaligned_le32() to do that. Failure
to do so can result in accessing invalid memory, leading to a
segfault.  Stephen Rothwell noticed this bug while cross-building an
x86_64 allmodconfig kernel on PowerPC.

We need to read from and write to 'buf' a byte at a time otherwise
it's possible we'll perform an unaligned access, which can lead to bus
errors when cross-building an x86 kernel on risc architectures.

Subject: [PATCH 3445/6423] usb: fix defined but not used warnings in hcd-pci.c

Shows up on ia64 builds (and possibly elsewhere) for configs that
don't set PM_RUNTIME or PM_SLEEP as follows:

drivers/usb/core/hcd-pci.c:383:12: warning: 'suspend_common' defined but not used
drivers/usb/core/hcd-pci.c:438:12: warning: 'resume_common' defined but not used

As per above, the functions are only used if RUNTIME/SLEEP are set,
so make the two functions conditional on these Kconfig values.

Subject: [PATCH 3448/6423] usb/storage: a couple defines from
 drivers/usb/storage/transport.h to include/linux/usb/storage.h

This moves the BOT data structures for CBW and CSW from drivers internal
header file to global include able file in include/.
The storage gadget is using the same name for CSW but a different for
CBW so I fix it up properly. The same goes for the ub driver and keucr
driver in staging.

Subject: [PATCH 3449/6423] usb/storage: redefine US_BULK_FLAG_IN and use it

US_BULK_FLAG_IN is defined as 1 and not used. The USB storage spec says
that bit 7 of flags within CBW defines the data direction. 1 is DATA-IN
(read from device) and 0 is the DATA-OUT. Bit 6 is obselete and bits 0-5
are reserved.
This patch redefines the unsued define US_BULK_FLAG_IN from 1 to 1 << 7
aka 0x80 and replaces the obvious users. In a following patch the
storage gadget will use it as well.

Subject: [PATCH 3450/6423] usb/gadget: use common defines within the storage
 gadget

This replaces the remaining defines which are available in "public"
include/ directory and are re-defined by the storage gadget.
This is patch is basicaly search & replace followed by the removal of
the defines.

Subject: [PATCH 3451/6423] usb/storage: remove Filler member from struct
 bulk_cs_wrap

As Alan Stern pointed out this member has nothing to do with the Command
Status Wrapper (CSW) as specified by the Universal Serial Bus Mass
Storage Class Bulk-Only Transport rev 1.0. It defines the structure
without the additional 18 filler bytes and defines the total size of the
struct to exactly 13 bytes. Larger responses should be dropped. All
in-tree users use a defines instead of sizeof() of this struct as far I
can tell.

Subject: [PATCH 3452/6423] USB: create module_usb_serial_driver macro

Now that Alan Stern has cleaned up the usb serial driver registration,
we have the ability to create a module_usb_serial_driver macro to make
things a bit simpler, like the other *_driver macros created.

But, as we need two functions here, we can't reuse the existing
module_driver() macro, so we need to roll our own.

Here's a patch implementing module_usb_serial_driver() and it converts
the pl2303 driver to use it, showing a nice cleanup.

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: Tue, 28 Feb 2012 13:36:35 -0800
Subject: [PATCH 3503/6423] USB: serial: add Fintek F81232 usb to serial driver

This is the first cut at a driver for the Fintek F81232 USB to serial
single port converter.  This provides the initial framework for the
device, and some data can move through it, but no line settings are
handled, so it's not that useful yet.  It does give people a starting
place to work from.

Thank to Fintek for providing samples and specifications, without which,
this driver would have never been able to be written.

Subject: [PATCH 3508/6423] [media] rtl2830: correct I2C functionality

Implement I2C functionality according to real RTL2830 demod.

Do not send register page in first byte of each I2C write, instead
use logic to set page using own write when needed. Page register is
physical register 0 as generally used.

Subject: [PATCH 3513/6423] [media] V4L: Add JPEG compression control class

The V4L2_CID_JPEG_CLASS control class is intended to expose various
adjustable parameters of JPEG encoders and decoders. Following controls
are defined:

 - V4L2_CID_JPEG_CHROMA_SUBSAMPLING,
 - V4L2_CID_JPEG_RESTART_INTERVAL,
 - V4L2_CID_JPEG_COMPRESSION_QUALITY,
 - V4L2_CID_JPEG_ACTIVE_MARKER.

This covers only a part of relevant standard specifications. More
controls should be added in future if required.

The purpose of V4L2_CID_JPEG_CLASS class is also to replace some
functionality covered by VIDIOC_S/G_JPEGCOMP ioctls, i.e. the JPEG
markers presence and compression quality control. The applications
and drivers should switch from the ioctl to control based API, as
described in the subsequent patches for the Media API DocBook.

Subject: [PATCH 3515/6423] x86: relocate get/set debugreg fcns to
 include/asm/debugreg.

Since we already have a debugreg.h header file, move the
assoc. get/set functions to it.  In addition to it being the
logical home for them, it has a secondary advantage.  The
functions that are moved use BUG().  So we really need to
have linux/bug.h in scope.  But asm/processor.h is used about
600 times, vs. only about 15 for debugreg.h -- so adding bug.h
to the latter reduces the amount of time we'll be processing
it during a compile.

Subject: [PATCH 3516/6423] spinlock: macroize assert_spin_locked to avoid
 bug.h dependency

In spinlock_api_smp.h we find a define for assert_raw_spin_locked
[which uses BUG_ON].   Then assert_spin_locked (as an inline) uses
it, meaning we need bug.h  But rather than put linux/bug.h in such
a highly used file like spinlock.h, we can just make the un-raw
version also a macro.  Then the required bug.h presence is limited
just to those few files who are actually doing the assert testing.

Subject: [PATCH 3518/6423] includecheck: delete any duplicate instances of
 module.h

Different tree maintainers picked up independently generated
trivial compile fixes based on linux-next testing, resulting
in some cases where a file would have got more than one addition
of module.h once everything was all merged together.

Delete any duplicates so includecheck isn't complaining about
anything related to module.h/export.h changes.

From 630d9c47274aa89bfa77fe6556d7818bdcb12992 Mon Sep 17 00:00:00 2001
From: Paul Gortmaker <paul.gortmaker@windriver.com>
Date: Wed, 16 Nov 2011 23:57:37 -0500
Subject: [PATCH 3519/6423] fs: reduce the use of module.h wherever possible

For files only using THIS_MODULE and/or EXPORT_SYMBOL, map
them onto including export.h -- or if the file isn't even
using those, then just delete the include.  Fix up any implicit
include dependencies that were being masked by module.h along
the way.

Subject: [PATCH 3520/6423] x86, tools: Remove unneeded header files from
 tools/build.c

We include <sys/sysmacros.h> and <asm/boot.h>, but none of those
header files actually provide anything this file needs.  Furthermore,
it breaks cross-compilation, so just remove them.

Subject: [PATCH 3521/6423] x86, build: Fix portability issues when
 cross-building

It would appear that we never actually generated a correct CRC when
building on a bigendian machine.  Depending on the word size, we would
either generate an all-zero CRC (64-bit machine) or a byte-swapped
CRC (32-bit machine.)  Fix the types used so we don't arbitrarily use
a 64-bit word to hold 32-bit numbers, and pass the CRC through
put_unaligned_le32() like all the other numbers.

The function radeon_bo_list_validate can cause a
bo to move, resulting in a different sync_obj
and a dependency to wait for this move to finish.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Storing pointers to the IBs in a static var just
leads to giving the same content back for all
cards in the system.

Subject: [PATCH 3536/6423] drm/radeon: fix deferred page-flip detection logic
 on Avivo-based ASICs

This fixes page-flip-related flickering observed on Iconia Tab W500.

The update_pending status returned by radeon_page_flip is very accurate on
Avivo-based ASICs when vpos is negative.

Experiments were conducted on several ASIC generations ranging from RS690
to Cayman where the page flip was artificially timed to occur at a specific
vpos. With negative vpos, overriding update_pending always lead to
flickering.

The same experiment on RV380 and RV410 showed that update_pending is not
accurate with negative vpos. In most cases update_pending == 1 is returned
although the flip would complete before the start of the next frame.
Therefore I left the behaviour unchanged for pre-AVIVO ASICs for
performance reasons, although this may result in flickering in rare cases.

This change also makes the logic a little easier to understand.

Subject: [PATCH 3540/6423] UBIFS: increase dumps loglevel

Most of the time we use the dumping function to dump something in case
of error. We use 'KERN_DEBUG' printk level, and the drawback is that users
do not see them in the console, while they see the other error messages
in the console. The result is that they send bug reports which does not
contain a lot of useful information. This patch changes the printk level
of the dump functions to 'KERN_ERR' to correct the situation.

I documented it in the MTD web site that people have to send the 'dmesg' output
when submitting bug reposts - it did not help.

Subject: [PATCH 3542/6423] UBIFS: do not use inc_link when i_nlink is zero

This patch changes the 'i_nlink' counter handling in 'ubifs_unlink()',
'ubifs_rmdir()' and 'ubifs_rename()'. In these function  'i_nlink' may become 0,
and if 'ubifs_jnl_update()' failed, we would use 'inc_nlink()' to restore
the previous 'i_nlink' value, which is incorrect from the VFS point of view and
would cause a 'WARN_ON()' (see 'inc_nlink() implementation).

This patches saves the previous 'i_nlink' value in a local variable and uses it
at the error path instead of calling 'inc_nlink()'. We do this only for the
inodes where 'i_nlink' may potentially become zero.

This change has been requested by Al Viro <viro@ZenIV.linux.org.uk>.

Subject: [PATCH 3543/6423] UBI: fix error handling in ubi_scan()

Two bad things can happen in ubi_scan():
1. If kmem_cache_create() fails we jump to out_si and call
   ubi_scan_destroy_si() which calls kmem_cache_destroy().
   But si->scan_leb_slab is NULL.
2. If process_eb() fails we jump to out_vidh, call
   kmem_cache_destroy() and ubi_scan_destroy_si() which calls
   again kmem_cache_destroy().

Subject: [PATCH 3545/6423] Bluetooth: change min_t() cast in hci_reassembly()

"count" is type int so the cast to __u16 truncates the high bits away
and triggers a Smatch static checker warning.  It looks like a high
value of count could cause a forever loop, but I didn't follow it
through to see if count is capped somewhere.

It seems that Lenovo machines (or codec chip itself?) leave the unsol
event tags and the enablement-flag from other pins bogusly even on the
unused pins.  Although this shouldn't be too critical, it's better to
clear them up sanely.

removal of the prototype multi-cluster capability means that all
outgoing messages are generated locally and already have this field

Optimizes routines that send payload messages so that they no longer
update the "originating node" and "originating port" fields of the
outgoing message header template, since these fields are initialized
when the sending port is created and never change thereafter. Also
optimizes the routine which updates the message header template when
a connection to a port is established, for the same reason.

Subject: [PATCH 3555/6423] xfs: merge xfs_qm_export_dquot into
 xfs_qm_scall_getquota

The is no good reason to have these two separate, and for the next change
we would need the full struct xfs_dquot in xfs_qm_export_dquot, so better
just fold the code now instead of changing it spuriously.

Subject: [PATCH 3556/6423] pinctrl: make the pinmux-pins more helpful

The debugfs file pinmux-pins used to tell which function was
enabled but now states simply which device owns the pin. Being
owned by the pinctrl driver itself means just that it's hogged
so be a bit more helpful by printing that.

ChangeLog v1->v2:
- Preserve the self-referential owner field, just clarify that
  when the pin controller states itself as owner this means
  that it's hogged.

Subject: [PATCH 3557/6423] pinctrl: re-order struct pinctrl_map

The lookup key in struct pinctrl_map is (.dev_name, .name). Re-order the
struct definition to put the lookup key fields first, and the result
values afterwards. To me at least, this slightly better reflects the
lookup process.

Update the documentation in a similar fashion.

Note: PIN_MAP*() macros aren't updated; I plan to update this once later
when enhancing the mapping table format to support pin config to reduce
churn.

Subject: [PATCH 3558/6423] pinctrl: move pinctrl-maps debugfs file to
 top-level

The debugfs file pinctrl-maps is a system-wide file, not specific to any
pin controller, so place it in the top-level directory.

Also, move the code implementing the file to keep the order of all the
functions matching the order they're created in pinctrl_init_*debugfs().
The only non-obvious change here is no private data is passed to
debugfs_create_file() or single_open().

Subject: [PATCH 3559/6423] [SCSI] libsas: poll for ata device readiness after
 reset

Use ata_wait_after_reset() to poll for link recovery after a reset.
This combined with sas_ha->eh_mutex prevents expander rediscovery from
probing phys in an intermediate state.  Local discovery does not have a
mechanism to filter link status changes during this timeout, so it
remains the responsibility of lldds to prevent premature port teardown.
Although once all lldd's support ->lldd_ata_check_ready() that could be
used as a gate to local port teardown.

The signature fis is re-transmitted when the link comes back so we
should be revalidating the ata device class, but that is left to a future
patch.

 child device is removed

Commit 56dd2c06 "[SCSI] libsas: Don't issue commands to devices that
have been hot-removed" marked the parent device of an end-device as gone
when all the phys to the end device have been deleted.

The expander device is still present until its parent is removed.  This
is a benign change until the smp_execute_task() path is taught to check
->gone.

Subject: [PATCH 3562/6423] [SCSI] libsas: fix sas_find_local_phy(), take phy
 references

In the direct-attached case this routine returns the phy on which this
device was first discovered.  Which is broken if we want to support
wide-targets, as this phy reference can become stale even though the
port is still active.

In the expander-attached case this routine tries to lookup the phy by
scanning the attached sas addresses of the parent expander, and BUG_ONs
if it can't find it.  However since eh and the libsas workqueue run
independently we can still be attempting device recovery via eh after
libsas has recorded the device as detached.  This is even easier to hit
now that eh is blocked while device domain rediscovery takes place, and
that libata is fed more timed out commands increasing the chances that
it will try to recover the ata device.

Arrange for dev->phy to always point to a last known good phy, it may be
stale after the port is torn down, but it will catch up for wide port
reconfigurations, and never be NULL.

Subject: [PATCH 3563/6423] [SCSI] libsas: don't recover 'gone' devices in
 sas_ata_hard_reset()

The commands that timeout when a disk is forcibly removed may trigger
libata to attempt recovery of the device.  If libsas has decided to
remove the device don't permit ata to continue to issue resets to its
last known phy.

The primary motivation for this patch is hotplug testing by writing 0 to
/sys/class/sas_phy/phyX/enable.  Without this check this test leads to
libata issuing a reset and re-enabling the device that wants to be torn
down.

Subject: [PATCH 3564/6423] drm/i915: Fix single msg gmbus_xfers writes

gmbus_xfer with a single message (particularly a single message write) would
set Bus Cycle Select to 100b, the Gen Stop cycle, instead of 101b,
No Index, Stop cycle. This would not start single message i2c transactions.

Also, gmbus_xfer done: will disable the interface without checking if
it is idle. In the case of writes, there will be no wait on status or delay
to ensure the write starts and completes before the interface is turned off.

Fixed the former issue by using the same cycle selection as used in the
I2C_M_RD for the write case.
GMBUS_CYCLE_WAIT | (i + 1 == num ? GMBUS_CYCLE_STOP : 0)
Fixed the latter by waiting on GMBUS_ACTIVE to deassert before disable.

Note from the grumpy d-i-n maintainer: The first hunk that changes the
gmbus read path is just cosmetics to align the code with the write
path.  I.e. the commit message above is slightly lying because the
first issue is _only_ with writes (and not simply "particularly").

Subject: [PATCH 3565/6423] zd1211rw: wait between setting hash table and
 powering radio on

I am running Debian testing kernel 3.1.0-1-amd64, using a 079b:0062 Sagem
XG-76NA 802.11bg stick.

Upon zd1211rw interface
bringup (ifconfig wlan0 up) I get the following timeout:

[  950.330573] zd1211rw 1-3:1.0: phy2
[  955.108510] zd1211rw 1-3:1.0: firmware version 4725

[snip]
[  955.204072] zd1211rw 1-3:1.0: error ioread32(CR_REG1): -110

A second ifconfig wlan0 up brings the interface up without problems.

After a bit more debugging, the call trace is the following:

[10241.028130] zd1211rw 1-3:1.0: zd_chip_lock_phy_regs: error

Adding a 10 milliseconds delay between the call to set_mc_hash() and
zd_chip_switch_radio_on() allows successful interface bringups in all
cases and matches what the vendor driver did.

In "cfg80211: no cookies in cfg80211_send_XXX()"
Holger Schurig removed the cookies in the calls
from mac80211 to cfg80211, but the ones in the
other direction were left in. Remove them now.

Subject: [PATCH 3568/6423] mac80211: dont call cfg80211 from
 ieee80211_send_deauth_disassoc

Instead of calling cfg80211 in ieee80211_send_deauth_disassoc()
pass out the frame and call it from the caller. That saves the
SKB allocation if we don't actually want to send the frame and
enables us to make the ordering smarter in the future.

Subject: [PATCH 3569/6423] mac80211: fix ieee80211_set_disassoc() sending
 DelBA

When ieee80211_set_disassoc() is called with the
tx argument set to true, it will send DelBA out
to the peer. This isn't useful or necessary in a
few cases where we do it today, those being when
we lost the connection or when the supplicant
explicitly asked us to not tell the AP.

Subject: [PATCH 3570/6423] mac80211: make deauth/disassoc sequence more
 natural

The association sequence looks (roughly) like
this now:
 * set BSSID
 * set station to EXIST state
 * send auth
 * set station to AUTH state
 * send assoc
 * set station to ASSOC state
 * set BSS info to associated

In contrast, the deauth/disassoc sequence is
the other way around:
 * clear BSSID/BSS info state
 * remove station
 * send deauth/disassoc
(in some cases the last two steps are reversed.)

This patch encodes the entire sequence in the
ieee80211_set_disassoc() function and changes
it to be like this, for good measure with an
explicit flush:
 * send deauth/disassoc
 * flush
 * remove station
 * clear BSSID/BSS info state

At least iwlwifi gets confused with the other
sequence in P2P mode and complains that it
wasn't able to flush the queues.

It should have been removed by commit "mwifiex: use cfg80211 dynamic
scan..." (7c6fa2a843..) after adding code to avoid an extra scan
during association because scan entries are valid for 15 seconds in
cfg80211 stack.

Instead of defining an 'enum', we can simply use 'u8' flag for WEP

'wpa_enabled' and 'wpa2_enabled'.

From 02f2f1a951f87644166926862ec32fb13511e2f3 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 27 Feb 2012 12:18:30 +0100
Subject: [PATCH 3573/6423] mac80211: handle non-bufferable MMPDUs correctly

This renames the IEEE80211_TX_CTL_POLL_RESPONSE
TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also
uses it for non-bufferable MMPDUs (all MMPDUs but
deauth, disassoc and action frames.)

Previously, mac80211 would let the MMPDU through
but not set the flag so drivers supporting some
hardware aids for avoiding the PS races would
then reject the frame.

Remove the enum il_calib. It defined one identifier: IL_CALIB_MAX.
Remove the function il4965_calib_free_results. It was doing nothing
because IL_CALIB_MAX is zero. Next, remove calib_results from the
il_priv structure and also remove the associated return
type/struct il_calib_result.

Subject: [PATCH 3578/6423] ath9k: decouple RX error checking for DFS

Previous RX error checking was done exclusive-or for different error
types and caused DFS pulse events to be dropped when other error
flags (e.g. CRC) were set simultaneously.

This patch decouples PHY error processing from other types and ensures
that all pulses detected by HW are accounted by the pattern detector.

Subject: [PATCH 3580/6423] i2c: imx: fix imx driver to work though signal is
 pending

Interrupt a test application for I2C based mc13xxx driven
touch panel, SIGINT, causes open event file descriptor to be
closed, which in turn causes I2C activity to mask PMIC local
interrupts. This eventually ends up in i2c_imx_bus_busy to
wait for some busy flag to toggle, but while waiting it would
find a signal pending and break. The final symptom is the
device is not closed down cleanly and thus not reopenable.

Do without check for pending signal.

Subject: [PATCH 3583/6423] i2c: export bit-banging algo functions

i915 has a hw i2c controller (gmbus) but for a bunch of stupid reasons
we need to be able to fall back to the bit-banging algo on gpio pins.

The current code sets up a 2nd i2c controller for the same i2c bus using
the bit-banging algo. This has a bunch of issues, the major one being
that userspace can directly access this fallback i2c adaptor behind
the drivers back.

But we need to frob a few registers before and after using fallback
gpio bit-banging, so this horribly fails.

The new plan is to only set up one i2c adaptor and transparently fall
back to bit-banging by directly calling the xfer function of the bit-
banging algo in the i2c core.

To make that possible, export the 2 i2c algo functions.

v2: As suggested by Jean Delvare, simply export the i2c_bit_algo
vtable instead of the individual functions.

Subject: [PATCH 3584/6423] drm/i915: merge struct intel_gpio into struct
 intel_gmbus

When we set up the gpio fallback, we always have a 1:1 relationship
with an intel_gmbus. Exploit that to store all gpio related data in
there, too. This is a preparation step to merge the tw i2c adapters
controlling the same bus into one.

Just mundane code-munging in this patch.

Subject: [PATCH 3585/6423] drm/i915: merge gmbus and gpio i2c adpater into one

... and directly call the newly exported i2c bit-banging functions.

The code is still pretty convoluted because we only set up the gpio
i2c stuff when actually falling back, resulting in more complexity
than necessary. This will be fixed up in the next patch.

v2: Use exported i2c_bit_algo vtable instead of exported functions.

Subject: [PATCH 3586/6423] drm/i915: i2c: unconditionally set up gpio fallback

This way we can simplify the setup and teardown a bit.

Because we don't actually allocate anything anymore for the force_bit
case, we can now convert that into a boolean.

Also and the functionality supported by the bit-banging together with
what gmbus can do, so that this doesn't randomly change any more.

v2: Chris Wilson noticed that I've mixed up && and & ...

v3: Clarify an if block as suggested by Eugeni Dodonov.

With the rework to merge the bit-banging fallback into the gmbus
i2c adapter we've gotten rid of the deadlock possibility that
originally lead to the disabling of this code.

This reverts the revert

That commit intended for 3.4 renamed IEEE80211_TX_CTL_POLL_RESPONSE as
IEEE80211_TX_CTL_NO_PS_BUFFER.  Meanwhile, "carl9170: fix frame delivery
if sta is in powersave mode" added a reference to
IEEE80211_TX_CTL_POLL_RESPONSE in the fixes stream for 3.3.  This simple
patch fixes that merge boo-boo.

Subject: [PATCH 3589/6423] xfs: include reservations in quota reporting

Report all quota usage including the currently pending reservations.  This
avoids the need to flush delalloc space before gathering quota information,
and matches quota enforcement, which already takes the reservations into
account.

This fixes xfstests 270.

Subject: [PATCH 3591/6423] [SCSI] isci: kill iphy->isci_port lookups

This field is a holdover from the OS abstraction conversion.  The stable
phy to port lookups are done via iphy->ownining_port under scic_lock.
After this conversion to use port->lldd_port the only volatile lookup is
the initial lookup in isci_port_formed().  After that point any lookup
via a successfully notified domain_device is guaranteed to be valid
until the domain_device is destroyed.

Delete ->start_complete as it is only set once and is set as a
consequence of the port going link up, by definition of getting a port
formed event the port is "ready".

While we are correcting port lookups also move the asd_sas_port table
out from under the isci_port.  This is to preclude any temptation to use
container_of() to convert an asd_sas_port to an isci_port, the
association is dynamic and under libsas control.

Subject: [PATCH 3592/6423] [SCSI] isci: kill isci_port->status

It only tracks whether the port is stopping in order to gate new devices
being discovered while the port is stopping.  However, since the check
and subsequent handling is unlocked there is nothing to stop the port
from going down immediately after the check.

Driver is already prepared to handle devices arriving on stale ports,
and those will be cleaned up by an eventual ->lldd_dev_gone()
notification.

Subject: [PATCH 3593/6423] [SCSI] isci: fix interpretation of "hard" reset

A hard reset to isci in the direct-attached case is one where the driver
internally manages debouncing the link.  In the sas-expander-attached
case a hard reset is one that clears affiliations.  The driver should
not be prematurely dropping affiliations at run time, that decision (to
force expander hard resets to ata devices) is left to userspace to
manage.  So, arrange for I_T_nexus resets to be sas-link-resets in the
expander-attached case and isci-hard-resets in the direct-attached case.

From 43a5ab151f0268459c4368292c2ddb2266b8f243 Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Thu, 8 Dec 2011 23:20:44 -0800
Subject: [PATCH 3594/6423] [SCSI] isci: stop interpreting ->lldd_lu_reset() as
 an ata soft-reset

Driving resets from libsas-eh is pre-mature as libata will make a
decision about performing a softreset.  Currently libata determines
whether to perform a softreset based on ata_eh_followup_srst_needed(),
and none of those conditions apply to isci.

Remove the srst implementation and translate ->lldd_lu_reset() for ata
devices as a request to drive a reset via libata-eh.

Subject: [PATCH 3596/6423] [SCSI] isci: remove bus and reset handlers

Remove ->eh_device_reset_handler() and ->eh_bus_reset_handler() for the
same reason they are not implemented for libata hosts, they cannot be
implemented reliably with ata-eh.  ATA error recovery wants to divert
all resets to the eh thread and wait for completion, these handlers may
be invoked from a non-blocking ioctl.

The other path they are called from is libsas-eh, and if we escalate
past I_T_nexus reset we have larger problems i.e. tear down all
in-flight commands in the domain potentially without notification to the
lldd if it has chosen not to implement ->lldd_clear_nexus_port() /
->lldd_clear_nexus_ha().

Subject: [PATCH 3597/6423] [SCSI] isci: remove IDEV_EH hack to disable
 "discovery-time" ata resets

Prior to commit 61aaff49 "isci: filter broadcast change notifications
during SMP phy resets" we borrowed the MVS_DEV_EH approach from the
mvsas driver for preventing ->lldd_I_T_nexus_reset() events during ata
discovery.  This hack was protecting against the old ->phy_reset() in
ata_bus_probe(), but since the conversion to the new error handling this
hack is preventing resets from reaching ata devices.

 vs completion race

When scrolling forward through the eh list (in a clear_q scenario) it is
possible to encounter commands that won the completion vs eh race.  Rather
than sprinkle more "if (!task)" throughout the handler just make a pass
through the list and delete the race winners before handling the rest.

ata_port lifetime in libata follows the host.  In libsas it follows the

completed it allows scsi_remove_target() to immediately proceed to
freeing the ata_port causing bug reports like:

Subject: [PATCH 3604/6423] [SCSI] libsas: kill spurious sas_put_device

Holdover from a patch rework, prior to the addition of SAS_DEV_DESTROY
we were holding a reference while the destruct was pending in case the
domain was torn down before the desctruct event ran.  That case is
covered by SAS_DEV_DESTROY, and the sas_put_device() just corrupts freed
memory, or worse frees the memory while another agent holds a reference.

Subject: [PATCH 3605/6423] [SCSI] libsas: improve debug statements

It's difficult to determine which domain_device is triggering error recovery,
so convert messages like:

  sas: ex 5001b4da000e703f phy08:T attached: 5001b4da000e7028
  sas: ex 5001b4da000e703f phy09:T attached: 5001b4da000e7029
  ...
  ata7: sas eh calling libata port error handler
  ata8: sas eh calling libata port error handler

...into:

  sas: ex 5001517e85cfefff phy05:T:9 attached: 5001517e85cfefe5 (stp)
  sas: ex 5001517e3b0af0bf phy11:T:8 attached: 5001517e3b0af0ab (stp)
  ...
  sas: ata7: end_device-21:1: dev error handler
  sas: ata8: end_device-20:0:5: dev error handler

which shows attached link rate, device type, and associates a
domain_device with its ata_port id to correlate messages emitted from
libata-eh.

As Doug notes, we can also take the opportunity to clarify expander phy
routing capabilities.

Make sas-port naming consistent with the expander-attached case whereby
the phy-id is the last digit in the port name.  Otherwise we get the
random behavior of the allocation order.

Subject: [PATCH 3607/6423] [SCSI] libsas: let libata recover links that fail
 to transmit initial sig-fis

libsas fails to discover all sata devices in the domain.  If a device fails
negotiation and does not transmit a signature fis the link needs recovery.
libata already understands how to manage slow to come up links, so treat these
conditions as ata device attach events for the purposes of creating an
ata_port.  This allows libata to manage retrying link bring up.

Rediscovery is modified to be careful about checking changes in dev_type.  It
looks like libsas leaks old devices if the sas address changes, but that's a
fix for another patch.

Subject: [PATCH 3609/6423] [SCSI] libsas: restore scan order

ata devices are always scanned after ssp.  Prior to the ata error
handling reworks libsas would tend to scan devices in ascending expander
phy order.  Restore this ordering by deferring ssp discovery to a
DISCE_PROBE event, and keep the probe order consistent with the
discovery order, not the placement of sata devices.

From 9508a66f898d46e726a318469312b45e0b1d078b Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Wed, 18 Jan 2012 20:47:01 -0800
Subject: [PATCH 3610/6423] [SCSI] libsas: async ata scanning

libsas ata error handling is already async but this does not help the
scan case.  Move initial link recovery out from under host->scan_mutex,
and delay synchronization with eh until after all port probe/recovery
work has been queued.

Device ordering is maintained with scan order by still calling
sas_rphy_add() in order of domain discovery.

Since we now scan the domain list when invoking libata-eh we need to be
careful to check for fully initialized ata ports.

Subject: [PATCH 3611/6423] [SCSI] libsas: fix lifetime of SAS_HA_FROZEN

Until all sas_tasks are known to no longer be in-flight this flag gates late
completions from colliding with error handling.  However, it must be cleared
prior to the submission of scsi_send_eh_cmnd() requests, otherwise those
commands will never be completed correctly.

This was spotted by slub debug:

Subject: [PATCH 3612/6423] [SCSI] libsas: revert ata srst

libata issues follow up srsts when the controller has a hard time
recording the signature-fis after a reset, or if the link supports port
multipliers.  libsas does not support port multipliers and no current
libsas lldds appear to need help retrieving the signature fis.  Revert
it for now to remove confusion.

After:
$ cat /sys/class/sas_phy/phy-6\:3/device_type
end device
$ cat /sys/class/sas_phy/phy-6\:3/target_port_protocols
sata

Also downgrade the phy_list_lock to _irq instead of _irqsave since
libsas will never call sas_get_port_device with interrupts disbled.

Subject: [PATCH 3615/6423] [SCSI] libsas: don't recover end devices attached
 to disabled phys

If userspace has decided to disable a phy the kernel should honor that
and not inadvertantly re-enable the phy via error recovery.  This is
more straightforward in the sata case where link recovery (via
libata-eh) is separate from sas_task cancelling in libsas-eh.  Teach
libsas to accept -ENODEV as a successful response from I_T_nexus_reset
('successful' in terms of not escalating further).

This is a more comprehensive fix then "libsas: don't recover 'gone'
devices in sas_ata_hard_reset()", as it is no longer sata-specific.

aic94xx does check the return value from sas_phy_reset() so if the phy
is disabled we proceed with clearing the I_T_nexus.

Subject: [PATCH 3616/6423] [SCSI] scsi_transport_sas: 'enable' phys on reset

If userspace requests a phy reset, treat that as a request for the phy
to be enabled since that is the effect on hardware.

Subject: [PATCH 3617/6423] bug.h: add include of it to various implicit C
 users

With bug.h currently living right in linux/kernel.h there
are files that use BUG_ON and friends but are not including
the header explicitly.  Fix them up so we can remove the
presence in kernel.h file.

Subject: [PATCH 3618/6423] [SCSI] isci: debug, provide state-enum-to-string
 conversions

Debugging the driver requires tracing the state transtions and tracing
state names is less work than decoding numbers.

From e462116afb1e436d4045167e7fe979405ae33d2b Mon Sep 17 00:00:00 2001
From: Dan Williams <dan.j.williams@intel.com>
Date: Fri, 10 Feb 2012 01:18:49 -0800
Subject: [PATCH 3619/6423] [SCSI] isci: improve phy event warnings

isci occasionally spews messages like:

isci 0000:03:00.0: sci_phy_event_handler: PHY starting substate machine received unexpected event_code b3940000

...which is not very helpful, since we don't know which controller,
which phy, the exact state, or a decode of the event.

Subject: [PATCH 3620/6423] [SCSI] isci: improvements in driver unloading
 routine

This patch fixes scenario where driver removal should be possible
only when driver is in READY state. Also it removes redundant
invocation of routine disabling SCU interrupts - this method is
called somewhere else in driver deinitialization path.

Subject: [PATCH 3623/6423] [SCSI] pm8001: Fix bogus interrupt state flag
 issue.

Static checker is giving following warning:
" error: calling 'spin_unlock_irqrestore()' with bogus flags"

The code flow is as shown below:
process_oq() --> process_one_iomb --> mpi_sata_completion

In 'mpi_sata_completion'
the first call for 'spin_unlock_irqrestore()' is with flags=0,
which is as good as 'spin_unlock_irq()' ( unconditional interrupt
enabling).

So for better performance 'spin_unlock_irqrestore()' can be replaced
with 'spin_unlock_irq()' and 'spin_lock_irqsave()' can be replaced by
'spin_lock_irq()'.

Subject: [PATCH 3624/6423] [SCSI] pm8001: Fix possible racing condition.

There is a possble racing scenario.

'process_oq' is called by two routines, as shown below.

pm8001_8001_dispatch = {
         .......

        .isr             = pm8001_chip_isr --> process_oq,// A
        .isr_process_oq  = process_oq,                   //  B
        .....
}

process_oq() --> process_one_iomb() --> mpi_sata_completion()

In 'mpi_sata_completion', "pm8001_ha->lock" is first released.
It means lock is taken before,  which is true for
the context A, as 'pm8001_ha->lock' is taken in 'pm8001_chip_isr()'

But for context B there is no lock taken before and pm8001_ha->lock
is unlocked in 'mpi_sata_completion()'. This may unlock the lock
taken in context A. Possible racing ??

If 'pm8001_ha->lock' is taken in 'process_oq()' instead of
'pm8001_chip_isr' then the above issue can be avoided.

Subject: [PATCH 3634/6423] TOMOYO: Fix mount flags checking order.

Userspace can pass in arbitrary combinations of MS_* flags to mount().

If both MS_BIND and one of MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE are
passed, device name which should be checked for MS_BIND was not checked because
MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE had higher priority than MS_BIND.

If both one of MS_BIND/MS_MOVE and MS_REMOUNT are passed, device name which
should not be checked for MS_REMOUNT was checked because MS_BIND/MS_MOVE had
higher priority than MS_REMOUNT.

Fix these bugs by changing priority to MS_REMOUNT -> MS_BIND ->
MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE -> MS_MOVE as with do_mount() does.

Also, unconditionally return -EINVAL if more than one of
MS_SHARED/MS_PRIVATE/MS_SLAVE/MS_UNBINDABLE is passed so that TOMOYO will not
generate inaccurate audit logs, for commit 7a2e8a8f "VFS: Sanity check mount
flags passed to change_mnt_propagation()" clarified that these flags must be
exclusively passed.

Subject: [PATCH 3636/6423] staging: zcache: fix length type mismatch

This fixes a type mismatch in the compression code where
a size_t pointer was cast to a unsigned int pointer.  On
little endian archs, there is no issue.  However on big
endian archs, the value is incorrect, taking the high
order bits and truncating the lower order bits.

Replace bitfield struct hbm_cmd with simple u8 as we
always access the value as whole. This allows us to remove
few ugly type casts
For possible further uses and documentation purposes we add
corresponding bitmask defines

Subject: [PATCH 3646/6423] staging: asus_oled: Remove superfluous loop

This patch removes a superfluous loop in asus_oled.c
The code is equivalent to do{...} while (0) and thus executes the code
exactly once -> so we can simply remove the loop.

Subject: [PATCH 3649/6423] Staging: crystalhd: Add global header

In the crystalhd_cmds.h there was a struct dependence bug:
the struct crystalhd_adp (which  is declared on crystalhd_lnx.h)
is used on  the crystalhd_cmd struct, however the crystalhd_lnx.h is
never included on crystalhd_cmds.h at all. Including the
crystalhd_lnx.h on crystalhd_cmds.h breaks the build,
many dependencies error occurrs, most of the type
"error: 'struct bar' has no member named 'foo'",
so I decided to reorganize the headers by adding a global header.

The gobal header crystalhd.h includes all the local headers.
The idea is that the crystalhd header will be the only included
by the others files, this will avoid the mess of many #include levels.

The order of the headers included by crystalhd.h considers the
dependencies among the headers.

Subject: [PATCH 3652/6423] Staging: wlan-ng: still setting wrong data

In commit 1ca1a92cc6 "Staging: wlan-ng: memsetting the wrong amount of
data" I changed the code so we didn't memset() past the end of the
msg1.bssid.data[] array.  Walter Harms noticed that it was weird that
we were setting the len to 6 when there were 7 elements in the array.
Pavel Roskin pointed out that the intent of the code was actually to
memset() msg1.bssid.data.data[] which is a 6 character array.

Subject: [PATCH 3653/6423] staging: r8712u: Fix regression introduced by
 commit a5ee652

In commit a5ee652 "staging: r8712u: Interface-state not fully tracked",
the private boolean "bup" was set false when the interface was brought down,
as that seemed appropriate. This change has not caused any problems when
using NetworkManager or manual control of the device; however, when wicd
control is used, there is a locking problem in wpa_supplicant, as shown in
https://bugzilla.kernel.org/show_bug.cgi?id=42818.

This fix reverts the only code change in commit a5ee652. My
analysis is that "bup" is badly named. In its present form, it
seems to indicate the up/down state of the device, but its usage
is more consistent with an initialized/uninitialized state. That
problem will be addressed in a later patch.

Note: Commit 8c213fa, which introdued asynchronous firmware loading
for this driver, exposed this bug to a greater extent. That bug
is addressed in the next patch in this series.

This bug is also responsible for the bug in
https://bugzilla.kernel.org/show_bug.cgi?id=42815. and this bug is
also part of the problems discussed at https://bugs.archlinux.org/task/27996#comment89950.

In commit 8c213fa "staging: r8712u: Use asynchronous firmware loading",
the command to release the firmware was placed in the wrong routine.

In combination with the bug introduced in commit a5ee652 "staging: r8712u:
Interface-state not fully tracked", the driver attempts to upload firmware
that had already been released. This bug is the source of one of the
problems in https://bugs.archlinux.org/task/27996#comment89833.

Subject: [PATCH 3655/6423] staging: r8712u: Fix regression in signal level
 after commit c6dc001

In commit c6dc001 "staging: r8712u: Merging Realtek's latest (v2.6.6).
Various fixes", the returned qual.qual member of the iw_statistics
struct was changed. For strong signals, this change made no difference;
however for medium and weak signals it results in a low signal that
shows considerable fluctuation, When using wicd for a medium-strength
AP, the value reported in the status line is reduced from 100% to 60% by
this bug.

This problem is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42826.

This reverts commit 79857e8e7b1ba740f8025b540f1e171c9a0a5d31.

To quote Shengzhou Liu:
	I'm sorry, please don't apply this patch.
	It appears not only on P1022 platform.
	There will be more breaks on other platforms regarding
	CTRL_PHY_CLK_VALID bit.
	I will post a new patch with well compatibility on all
	platforms as soon as I get necessary confirmations.

exynos4210-cpufreq.c is not buildable on non-exynos builds, so it's
pointless allowing this option to be exposed.  Fix this by adding a
dependency on ARCH_EXYNOS.

Subject: [PATCH 3661/6423] [CPUFREQ] Add S3C2416/S3C2450 cpufreq driver

The S3C2416/S3C2450 SoCs support two sources for the armclk.

The first source is the so called armdiv which divides the msysclk down
to provide necessary cpu rates. In this mode the core voltage must be
always at 1.3V. The frequency from the armdiv is not allowed to be
lower than the hclk frequency.

In the second mode the armclk can be sourced directly from the hclk in
the so called "dynamic voltags scaling" (dvs) mode. Here the armdiv
isn't used at all. Also in this mode the core voltage may be lowered.
Existing hardware and tests with it suggest 1.0V as sufficient.

When changing the clock source to the armdiv from the hclk, the SoC
shows stability issues if the new frequency is higher than the current
hclk frequency. Hence the driver always forces the armdiv to the hclk
frequency before the source change and lets the cpufreq issue another
set_target call for higher frequencies.

To mark the hclk frequency as lower as the corresponding armdiv
frequency it is set 1MHz below the real frequency. This lets the cpufreq
framework change between 133MHz based on hclk and 133MHz based on armdiv
at will.

Subject: [PATCH 3662/6423] [CPUFREQ] CPUfreq ondemand: update sampling rate
 without waiting for next sampling

When a new sampling rate is shorter than the current one, (e.g., 1 sec
--> 10 ms) regardless how short the new one is, the current ondemand
mechanism wait for the previously set timer to be expired.

For example, if the user has just expressed that the sampling rate
should be 10 ms from now and the previous was 1000 ms, the new rate may
become effective 999 ms later, which could be not acceptable for the
user if the user has intended to speed up sampling because the system is
expected to react to CPU load fluctuation quickly from __now__.

In order to address this issue, we need to cancel the previously set
timer (schedule_delayed_work) and reset the timer if resetting timer is
expected to trigger the delayed_work ealier.

Subject: [PATCH 3667/6423] ath6kl: Refactor ath6kl_wmi_control_rx()

Split the wmi event processing into the one which needs to be
vif specific and the reset. This is a step towards avoiding
the need for wiphy and a netdev registration before getting
any message from firmware.

Subject: [PATCH 3668/6423] ath6kl: Skip vif index validation in ath6kl_rx()
 for wmi events

When the wmi event is vif specific, the validation of vif index
is taken care in ath6kl_wmi_proc_events_iface(). This also avoids
the need for a netdev to be registered while receiving initial events
like "target_ready" and "regulatory domain".

Subject: [PATCH 3669/6423] ath6kl: Defer wiphy and netdev registration till
 the end of ath6kl_core_init()

This makes the wiphy and initial netdev registration the last step
in dev initialization. Apart from the fact that this looks right,
it can also be used to setup wiphy with the regulatory information
received from firmware after uploading the firmware. Also it fixes
a FIXME in ath6kl_core_init() where mac address is copied into
netdev->dev_addr, ath6kl_interface_add() takes care of this as well.

Subject: [PATCH 3672/6423] ath6kl: Clear the IE in firmware if not set

Remove check so that IE in firmware is cleared if not set. Without this fix, any
previously set IE will be used incorrectly in the next frame. For example,
consider the scenario where a P2P device scan is followed by a regular station
scan. The P2P IE set by the P2P scan needs to be cleared, otherwise the station
scan will contain the P2P IE.

Subject: [PATCH 3673/6423] ath6kl: implement hidden ssid

The ath6kl FW does not distinguish between different types of hidden
SSIDs (empty or null), so treat all cfg80211 requests for hidden ssid
the same.

Subject: [PATCH 3675/6423] ath6kl: Collect residue firmware logs

Collect residue firmware logs following firmware assert.
Firmware sends logs to host once the 1500 byte log buffer
has been filled. At time of assert, there could be residue
logs lying in the firmware. This patch pulls those residue
logs. This would give the full picture of the firmware.

Subject: [PATCH 3677/6423] e100: Support RXALL feature flag.

This allows the NIC to receive packets with bad FCS
and other errors.  Good for sniffing packets on flakey
networks.

v4:  Only flax rx-over-length errors if pkt is beyond
   maximum expected packet size, not just beyond the MTU.
   This matches the existing logic for this counter.

Subject: [PATCH 3680/6423] e1000e: use msleep instead of mdelay

The e1000_link_stall_workaround_lv() function is always called in non-
atomic context so it should use msleep instead of mdelay.  Also, remove
unnecessary #include <linux/delay.h>.

Subject: [PATCH 3684/6423] rtnetlink: Fix VF IFLA policy

Add VF spoof check to IFLA policy.  The original patch I submitted to
add the spoof checking feature to rtnl failed to add the proper policy
rule that identifies the data type and len.  This patch corrects that
oversight.  No bugs have been reported against this but it may cause
some problem for the netlink message parsing that uses the policy
table.

Subject: [PATCH 3685/6423] ath6kl: Fix random system lockup

The commit "ath6kl: Use a mutex_lock to avoid
race in diabling and handling irq" introduces a
state where ath6kl_sdio_irq_handler() would be waiting
to claim the sdio function for receive indefinitely
when things happen in the following order.

ath6kl_sdio_irq_handler()
	- aquires mtx_irq
	- sdio_release_host()
					ath6kl_sdio_irq_disable()
						- sdio_claim_host()
						- sleep on mtx_irq
	ath6kl_hif_intr_bh_handler()
		- (indefinitely) wait for the sdio
		  function to be released to exclusively claim
		  it again for receive operation.

Fix this by replacing the mtx_irq with an atomic
variable and a wait_queue.

kvalo: add ath6kl_sdio_is_on_irq() due to open parenthesis alignment

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This patch adds reporting of 1 wheel button and 8 strip buttons for Intuos4 WL.
The buttons are reported as BTN_0 to BTN_9. The change of type butstate variable
is required as the old type 'char' couldn't store state of 9 buttons. The change
is not affecting Graphire tablet as it only uses first 2 bits of 'butstate'.

The hardware-initializtion part of the AMD IOMMU driver is
split out into a seperate function. This function can now be
called either from amd_iommu_init() itself or any other
place if the hardware needs to be ready earlier. This will
be used to implement interrupt remapping for AMD.

Subject: [PATCH 3696/6423] NFSv4.1: Get rid of redundant NFS4CLNT_LAYOUTRECALL
 tests

The NFS4CLNT_LAYOUTRECALL tests in pnfs_layout_process and
pnfs_update_layout are redundant.

In the case of a bulk layout recall, we're always testing for
the NFS_LAYOUT_BULK_RECALL flay anyway.
In the case of a file or segment recall, the call to
pnfs_set_layout_stateid() updates the layout_header 'barrier'
sequence id, which triggers the test in pnfs_layoutgets_blocked()
and is less race-prone than NFS4CLNT_LAYOUTRECALL anyway.

Subject: [PATCH 3697/6423] NFSv4.1: Get rid of NFS4CLNT_LAYOUTRECALL

The NFS4CLNT_LAYOUTRECALL bit is a long-term impediment to scalability. It
basically stops all other recalls by a given server once any layout recall
is requested.

If the recall is for a different file, then we don't care.
If the recall applies to the same file, then we're in one of two situations:
Either we are in the case of a replay of an existing request, in which case
the session is supposed to deal with matters, or we are dealing with a
completely different request, in which case we should just try to process
it.

Subject: [PATCH 3700/6423] usb: core: hcd: make hcd->irq unsigned

There's really no point in having hcd->irq as a
signed integer when we consider the fact that
IRQ 0 means NO_IRQ. In order to avoid confusion,
make hcd->irq unsigned and fix users who were
passing -1 as the IRQ number to usb_add_hcd.

Subject: [PATCH 3702/6423] Bluetooth: Fix init sequence for some CSR based
 controllers

Some CSR controllers will generate a spontaneous reset during init and
just eat up any pending command without sending a command complete for
it. This patch solves the issue by just resending whatever was the last
sent command. hci_send_cmd is not used since we need to bypass all other
commands in the send queue.

+Samsung S5P/EXYNOS4 FIMC driver
+
+Copyright (C) 2012 Samsung Electronics Co., Ltd.
+---------------------------------------------------------------------------
+
+The FIMC (Fully Interactive Mobile Camera) device available in Samsung
+SoC Application Processors is an integrated camera host interface, color
+space converter, image resizer and rotator.  It's also capable of capturing
+data from LCD controller (FIMD) through the SoC internal writeback data
+path.  There are multiple FIMC instances in the SoCs (up to 4), having
+slightly different capabilities, like pixel alignment constraints, rotator
+availability, LCD writeback support, etc. The driver is located at
+drivers/media/video/s5p-fimc directory.
+
+1. Supported SoCs
+=================
+
+S5PC100 (mem-to-mem only), S5PV210, EXYNOS4210
+
+2. Supported features
+=====================
+
+ - camera parallel interface capture (ITU-R.BT601/565);
+ - camera serial interface capture (MIPI-CSI2);
+ - memory-to-memory processing (color space conversion, scaling, mirror
+   and rotation);
+ - dynamic pipeline re-configuration at runtime (re-attachment of any FIMC
+   instance to any parallel video input or any MIPI-CSI front-end);
+ - runtime PM and system wide suspend/resume
+
+Not currently supported:
+ - LCD writeback input
+ - per frame clock gating (mem-to-mem)
+
+3. Files partitioning
+=====================
+
+- media device driver
+  drivers/media/video/s5p-fimc/fimc-mdevice.[ch]
+
+ - camera capture video device driver
+  drivers/media/video/s5p-fimc/fimc-capture.c
+
+ - MIPI-CSI2 receiver subdev
+  drivers/media/video/s5p-fimc/mipi-csis.[ch]
+

+  drivers/media/video/s5p-fimc/fimc-core.c

+  drivers/media/video/s5p-fimc/fimc-core.h
+  drivers/media/video/s5p-fimc/fimc-reg.h
+  drivers/media/video/s5p-fimc/regs-fimc.h
+
+4. User space interfaces
+========================
+
+4.1. Media device interface
+
+The driver supports Media Controller API as defined at
+http://http://linuxtv.org/downloads/v4l-dvb-apis/media_common.html
+The media device driver name is "SAMSUNG S5P FIMC".
+
+The purpose of this interface is to allow changing assignment of FIMC instances
+to the SoC peripheral camera input at runtime and optionally to control internal
+connections of the MIPI-CSIS device(s) to the FIMC entities.
+
+The media device interface allows to configure the SoC for capturing image
+data from the sensor through more than one FIMC instance (e.g. for simultaneous
+viewfinder and still capture setup).
+Reconfiguration is done by enabling/disabling media links created by the driver
+during initialization. The internal device topology can be easily discovered
+through media entity and links enumeration.
+
+4.2. Memory-to-memory video node
+
+V4L2 memory-to-memory interface at /dev/video? device node.  This is standalone
+video device, it has no media pads. However please note the mem-to-mem and
+capture video node operation on same FIMC instance is not allowed.  The driver
+detects such cases but the applications should prevent them to avoid an
+undefined behaviour.
+
+4.3. Capture video node
+
+The driver supports V4L2 Video Capture Interface as defined at:
+http://linuxtv.org/downloads/v4l-dvb-apis/devices.html
+
+At the capture and mem-to-mem video nodes only the multi-planar API is
+supported. For more details see:
+http://linuxtv.org/downloads/v4l-dvb-apis/planar-apis.html
+
+4.4. Camera capture subdevs
+
+Each FIMC instance exports a sub-device node (/dev/v4l-subdev?), a sub-device
+node is also created per each available and enabled at the platform level
+MIPI-CSI receiver device (currently up to two).
+
+4.5. sysfs
+
+In order to enable more precise camera pipeline control through the sub-device
+API the driver creates a sysfs entry associated with "s5p-fimc-md" platform
+device. The entry path is: /sys/platform/devices/s5p-fimc-md/subdev_conf_mode.
+
+In typical use case there could be a following capture pipeline configuration:
+sensor subdev -> mipi-csi subdev -> fimc subdev -> video node
+
+When we configure these devices through sub-device API at user space, the
+configuration flow must be from left to right, and the video node is
+configured as last one.
+When we don't use sub-device user space API the whole configuration of all
+devices belonging to the pipeline is done at the video node driver.
+The sysfs entry allows to instruct the capture node driver not to configure
+the sub-devices (format, crop), to avoid resetting the subdevs' configuration
+when the last configuration steps at the video node is performed.
+
+For full sub-device control support (subdevs configured at user space before
+starting streaming):
+# echo "sub-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+
+For V4L2 video node control only (subdevs configured internally by the host
+driver):
+# echo "vid-dev" > /sys/platform/devices/s5p-fimc-md/subdev_conf_mode
+This is a default option.
+
+5. Device mapping to video and subdev device nodes
+==================================================
+
+There are associated two video device nodes with each device instance in
+hardware - video capture and mem-to-mem and additionally a subdev node for
+more precise FIMC capture subsystem control. In addition a separate v4l2
+sub-device node is created per each MIPI-CSIS device.
+
+How to find out which /dev/video? or /dev/v4l-subdev? is assigned to which
+device?
+
+You can either grep through the kernel log to find relevant information, i.e.
+# dmesg | grep -i fimc
+(note that udev, if present, might still have rearranged the video nodes),
+
+or retrieve the information from /dev/media? with help of the media-ctl tool:
+# media-ctl -p
+
+6. Platform support
+===================
+
+The machine code (plat-s5p and arch/arm/mach-*) must select following options
+
+CONFIG_S5P_DEV_FIMC0       mandatory
+CONFIG_S5P_DEV_FIMC1  \
+CONFIG_S5P_DEV_FIMC2  |    optional
+CONFIG_S5P_DEV_FIMC3  |
+CONFIG_S5P_SETUP_FIMC /
+CONFIG_S5P_SETUP_MIPIPHY \
+CONFIG_S5P_DEV_CSIS0     | optional for MIPI-CSI interface
+CONFIG_S5P_DEV_CSIS1     /
+
+Except that, relevant s5p_device_fimc? should be registered in the machine code
+in addition to a "s5p-fimc-md" platform device to which the media device driver
+is bound.  The "s5p-fimc-md" device instance is required even if only mem-to-mem
+operation is used.
+
+The description of sensor(s) attached to FIMC/MIPI-CSIS camera inputs should be
+passed as the "s5p-fimc-md" device platform_data.  The platform data structure
+is defined in file include/media/s5p_fimc.h.
+
+7. Build
+========
+
+This driver depends on following config options:
+PLAT_S5P,
+PM_RUNTIME,
+I2C,
+REGULATOR,
+VIDEO_V4L2_SUBDEV_API,
+
+If the driver is built as a loadable kernel module (CONFIG_VIDEO_SAMSUNG_S5P_FIMC=m)
+two modules are created (in addition to the core v4l2 modules): s5p-fimc.ko and
+optional s5p-csis.ko (MIPI-CSI receiver subdev).

Subject: [PATCH 3705/6423] drm/i915: Only clear the GPU domains upon a
 successful finish

By clearing the GPU read domains before waiting upon the buffer, we run
the risk of the wait being interrupted and the domains prematurely
cleared. The next time we attempt to wait upon the buffer (after
userspace handles the signal), we believe that the buffer is idle and so
skip the wait.

There are a number of bugs across all generations which show signs of an
overly haste reuse of active buffers.

Such as:

  https://bugs.freedesktop.org/show_bug.cgi?id=29046
  https://bugs.freedesktop.org/show_bug.cgi?id=35863
  https://bugs.freedesktop.org/show_bug.cgi?id=38952
  https://bugs.freedesktop.org/show_bug.cgi?id=40282
  https://bugs.freedesktop.org/show_bug.cgi?id=41098
  https://bugs.freedesktop.org/show_bug.cgi?id=41102
  https://bugs.freedesktop.org/show_bug.cgi?id=41284
  https://bugs.freedesktop.org/show_bug.cgi?id=42141

A couple of those pre-date i915_gem_object_finish_gpu(), so may be
unrelated (such as a wild write from a userspace command buffer), but
this does look like a convincing cause for most of those bugs.

Subject: [PATCH 3706/6423] PCI / PCIe: Introduce command line option to
 disable ARI

There are PCIe devices on the market that report ARI support but
then fail to initialize correctly when ARI is actually used.  This
leads to situations in which kernels 2.6.34 and newer fail to handle
systems where the previous kernels worked without any apparent
problems.  Unfortunately, it is currently unknown how many such
devices are there.

For this reason, introduce a new kernel command line option,
pci=noari, allowing users to disable PCIe ARI altogether if they
see problems with PCIe device initialization.

Subject: [PATCH 3707/6423] mdio: Export mdio.h to userland

The ID packing definitions are needed by userland and the register
definitions may also be useful there.

Do not export mdio_phy_id_{is_c45,prtad,devad}() as the use of bool is
problematic and it's not that useful to export only a subset of these.

Do not export MDIO_SUPPORTS_{C22,C45} directly; these flags are only
exposed to userland through struct ethtool_cmd so they should be
defined alongside that with appropriate names.

Subject: [PATCH 3708/6423] ethtool, mdio, mii: Specify MDIO information fields
 in struct ethtool_cmd

Add comments for ethtool_cmd::phy_address and
ethtool_cmd::mdio_support, and definitions of the flags currently
used in mdio_support.

In the mdio library, assert that its own flags continue to match those
in the ethtool interface.

In the mii library, use the ethtool flag definition and stop
including <linux/mdio.h>.

Subject: [PATCH 3710/6423] Bluetooth: mgmt: Refactor hci_dev lookup for
 commands

Almost all mgmt commands need to lookup a struct hci_dev based on the
index received within the mgmt headers. It makese therefore sense to
look this up in a single place and then just pass the hdev pointer to
each command handler function.

Subject: [PATCH 3711/6423] Bluetooth: mgmt: Initialize HCI_MGMT flag for any
 command

The read_controller_info is typically the first command that user space
sends when taking a controller into use. This is also the reason why
this command has been used as the trigger to set the HCI_MGMT flag.
However, when not running the user-space daemon and using command line
tools it is possible that read_controller_info is not the first
controller specific command. This patch moves the HCI_MGMT
initialization to a generic place where it will be set for whatever
happens to be the first mgmt command targetting a specific controller.

Subject: [PATCH 3712/6423] Bluetooth: mgmt: Move command handlers into a table

By moving the command handlers into a table (the index being equal to
the opcode) the lookup is made a bit more efficient. Having a struct to
describe each handler also paves the way to add more meta-data for each
handler, e.g. the minimum message size for the command and allow
handling of common tasks like this in a centralized place.

From 9d1acbfb774fa5e043a44adedfcc36c9837a5e61 Mon Sep 17 00:00:00 2001
From: Johan Hedberg <johan.hedberg@intel.com>
Date: Thu, 1 Mar 2012 22:23:42 +0200
Subject: [PATCH 3713/6423] Bluetooth: mgmt: Add defines for command sizes

These defines are shorter than "sizeof(struct mgmt_cp_foo_bar...)" and
will be helpful when extending the command lookup table to contain the
expected command size information.

From: Johan Hedberg <johan.hedberg@intel.com>
Date: Thu, 1 Mar 2012 22:24:41 +0200
Subject: [PATCH 3714/6423] Bluetooth: mgmt: Centralize message length checks

This patch moves the command length information into the command handler
table allowing the removal of length checks from the handler functions
and doing the check in a single place before calling the handler
function.

From 57e62324e469e092ecc6c94a7a86fe4bd6ac5172 Mon Sep 17 00:00:00 2001
From: Bryan Schumaker <bjschuma@netapp.com>
Date: Fri, 24 Feb 2012 14:14:51 -0500
Subject: [PATCH 3715/6423] NFS: Store the legacy idmapper result in the
 keyring

This patch removes the old hashmap-based caching and instead uses a
"request key actor" to place an upcall to the legacy idmapper rather
than going through /sbin/request-key.  This will only be used as a
fallback if /etc/request-key.conf isn't configured to use nfsidmap.

Subject: [PATCH 3716/6423] NFSv4: Send implementation id with exchange_id

Send the nfs implementation id in EXCHANGE_ID requests unless the module
parameter nfs.send_implementation_id is 0.

This adds a CONFIG variable for the nii_domain that defaults to "kernel.org".

Subject: [PATCH 3720/6423] Bluetooth: Update L2CAP timeout constants to use
 msecs_to_jiffies

The L2CAP timeout constants are always used in form of jiffies. So just
include the conversion from msecs in the define itself. This has the
advantage of making the code where the timeout is used more readable.

Subject: [PATCH 3721/6423] Bluetooth: Update MGMT and SMP timeout constants to
 use msecs_to_jiffies

The MGMT and SMP timeout constants are always used in form of jiffies. So
just include the conversion from msecs in the define itself. This has the
advantage of making the code where the timeout is used more readable.

Subject: [PATCH 3729/6423] usb: dwc3: use devm_xxx functions

This patch enables to use devm_xxx functions during probing driver.
The devm_xxx series functions are able to release resource when the
driver is detatched. We can remove several codes to release resources
in the probe function.

If we have a non-ISOC endpoint, we will not have a Link TRB
pointing to the beginning of the TRB pool. On such endpoints,
we don't want to let the driver wrap around the TRB pool
otherwise controller will hang waiting for a valid TRB.

Subject: [PATCH 3745/6423] pinctrl: enhance pinctrl_get() to handle multiple
 functions

At present, pinctrl_get() assumes that all matching mapping table entries
have the same "function" value, albeit potentially applied to different
pins/groups.

This change removes this restriction; pinctrl_get() can now handle a set
of mapping tables where different functions are applied to the various
pins/groups.

Subject: [PATCH 3746/6423] pinctrl: introduce PINCTRL_STATE_DEFAULT, define
 hogs as that state

This provides a single centralized name for the default state.

Update PIN_MAP_* macros to use this state name, instead of requiring the
user to pass a state name in.

With this change, hog entries in the mapping table are defined as those
with state name PINCTRL_STATE_DEFAULT, i.e. all entries have the same
name. This interacts badly with the nested iteration over mapping table
entries in pinctrl_hog_maps() and pinctrl_hog_map() which would now
attempt to claim each hog mapping table entry multiple times. Replacing
the custom hog code with a simple pinctrl_get()/pinctrl_enable().

Update documentation and mapping tables to use this.

Subject: [PATCH 3747/6423] pinctrl: assume map table entries can't have a NULL
 name field

pinctrl_register_mappings() already requires that every mapping table
entry have a non-NULL name field.

Logically, this makes sense too; drivers should always request a specific
named state so they know what they're getting. Relying on getting the
first mentioned state in the mapping table is error-prone, and a nasty
special case to implement, given that a given the mapping table may define
multiple states for a device.

Remove a small part of the documentation that talked about optionally
requesting a specific state; it's mandatory now.

Subject: [PATCH 3752/6423] NFS: Ensure we display the minor version correctly
 in /proc/mounts etc.

The 'minorversion' mount option is now deprecated, so we need to display
the minor version number in the 'vers=' format.

Subject: [PATCH 3754/6423] x86/PCI: add spinlock held check to
 'pcibios_fwaddrmap_lookup()'

'pcibios_fwaddrmap_lookup()' is used to maintain FW-assigned BIOS BAR
values for reinstatement when normal resource assignment attempts
fail and must be called with the 'pcibios_fwaddrmap_lock' spinlock
held.

This patch adds a WARN_ON notification if the spinlock is not currently
held by the caller.

Subject: [PATCH 3756/6423] NFS: Clean up debugging in decode_pathname()

I noticed recently that decode_attr_fs_locations() is not generating
very pretty debugging output.  The pathname components each appear on
a separate line of output, though that does not appear to be the
intended display behavior.  The preferred way to generate continued
lines of output on the console is to use pr_cont().

Note that incoming pathname4 components contain a string that is not
necessarily NUL-terminated.  I did actually see some trailing garbage
on the console.  In addition to correcting the line continuation
problem, add a string precision format specifier to ensure that each
component string is displayed properly, and that vsnprintf() does
not Oops.

Someone pointed out that allowing incoming network data to possibly
generate a console line of unbounded length may not be such a good
idea.  Since this output will rarely be enabled, and there is a hard
upper bound (NFS4_PATHNAME_MAXCOMPONENTS) in our implementation, this
is probably not a major concern.

It might be useful to additionally sanity-check the length of each
incoming component, however.  RFC 3530bis15 does not suggest a maximum
number of UTF-8 characters per component for either the pathname4 or
component4 types.  However, we could invent one that is appropriate
for our implementation.

Another possibility is to scrap all of this and print these pathnames
in upper layers after a reasonable amount of sanity checking in the
XDR layer.  This would give us an opportunity to allocate a full
buffer so that the whole pathname would be output via a single
dprintk.

Introduced by commit 7aaa0b3b: "NFSv4: convert fs-locations-components
to conform to RFC3530," (June 9, 2006).

Subject: [PATCH 3758/6423] SUNRPC: Use RCU to dereference the rpc_clnt.cl_xprt
 field

A migration event will replace the rpc_xprt used by an rpc_clnt.  To
ensure this can be done safely, all references to cl_xprt must now use
a form of rcu_dereference().

Special care is taken with rpc_peeraddr2str(), which returns a pointer
to memory whose lifetime is the same as the rpc_xprt.

Subject: [PATCH 3759/6423] SUNRPC: Move clnt->cl_server into struct rpc_xprt

When the cl_xprt field is updated, the cl_server field will also have
to change.  Since the contents of cl_server follow the remote endpoint
of cl_xprt, just move that field to the rpc_xprt.

Subject: [PATCH 3760/6423] SUNRPC: Add API to acquire source address

NFSv4.0 clients must send endpoint information for their callback
service to NFSv4.0 servers during their first contact with a server.
Traditionally on Linux, user space provides the callback endpoint IP
address via the "clientaddr=" mount option.

During an NFSv4 migration event, it is possible that an FSID may be
migrated to a destination server that is accessible via a different
source IP address than the source server was.  The client must update
callback endpoint information on the destination server so that it can
maintain leases and allow delegation.

Without a new "clientaddr=" option from user space, however, the
kernel itself must construct an appropriate IP address for the
callback update.  Provide an API in the RPC client for upper layer
RPC consumers to acquire a source address for a remote.

The mechanism used by the mount.nfs command is copied: set up a
connected UDP socket to the designated remote, then scrape the source
address off the socket.  We are careful to select the correct network
namespace when setting up the temporary UDP socket.

Subject: [PATCH 3762/6423] NFS: Make clientaddr= optional

For NFSv4 mounts, the clientaddr= mount option has always been
required.  Now we have rpc_localaddr() in the kernel, which was
modeled after the same logic in the mount.nfs command that constructs
the clientaddr= mount option.  If user space doesn't provide a
clientaddr= mount option, the kernel can now construct its own.

For debugging, introduce a simplistic function to print NFS file
handles on the system console.  The main function is hooked into the
dprintk debugging facility, but you can directly call the helper,
_nfs_display_fhandle(), if you want to print a handle unconditionally.

Subject: [PATCH 3765/6423] NFS: Introduce NFS_ATTR_FATTR_V4_LOCATIONS

The Linux NFS client must distinguish between referral events (which
it currently supports) and migration events (which it does not yet
support).

In both types of events, an fs_locations array is returned.  But upper
layers, not the XDR layer, should make the distinction between a
referral and a migration.  There really isn't a way for an XDR decoder
function to distinguish the two, in general.

Slightly adjust the FATTR flags returned by decode_fs_locations()
to set NFS_ATTR_FATTR_V4_LOCATIONS only if a non-empty locations
array was returned from the server.  Then have logic in nfs4proc.c
distinguish whether the locations array is for a referral or
something else.

Subject: [PATCH 3766/6423] NFS: Request fh_expire_type attribute in "server
 caps" operation

The fh_expire_type file attribute is a filesystem wide attribute that
consists of flags that indicate what characteristics file handles
on this FSID have.

Our client doesn't support volatile file handles.  It should find
out early (say, at mount time) whether the server is going to play
shenanighans with file handles during a migration.

Subject: [PATCH 3768/6423] Bluetooth: Remove HCI_PI_MGMT_INIT flag for sockets

This flag is of no use right now and is in fact harmful in that it
prevents the HCI_MGMT flag to be set for any controllers that may need
it after the first one that bluetoothd takes into use (the flag is
cleared for the first controller so any subsequent ones through the same
bluetoothd mgmt socket never get the HCI_MGMT flag set).

Subject: [PATCH 3769/6423] Bluetooth: mgmt: Fix updating local name when
 powering on

When powering on we need to apply whatever name has been set through
mgmt_set_local_name. The appropriate place for this is mgmt_powered()
and not hci_setup() since this needs to be applied also if the HCI init
sequence was already completed but the adapter was still "powered off"
from a mgmt perspective due the the HCI_AUTO_OFF still being set.

Subject: [PATCH 3770/6423] Bluetooth: Don't force DISCOVERY_STOPPED state in
 inquiry_cache_flush

We are not supposed to force DISCOVERY_STOPPED in inquiry_cache_flush
because we may break the discovery state machine. For instance, during
interleaved discovery, when we are about to start inquiry, the state
machine forcibly goes to DISCOVERY_STOPPED while it should stay in
DISCOVERY_FINDING state.

This problem results in unexpected behaviors such as sending two
mgmt_discovering events to userspace (when only one event is expected)
and Stop Discovery failures.

Subject: [PATCH 3771/6423] usb: cp210x: Update to support CP2105 and multiple
 interface devices

This patch updates the cp210x driver to support CP210x multiple
interface devices devices from Silicon Labs. The existing driver
always sends control requests to interface 0, which is hardcoded in
the usb_control_msg function calls. This only allows for single
interface devices to be used, and causes a bug when using ports on an
interface other than 0 in the multiple interface devices.

Here are the changes included in this patch:
- Updated the device list to contain the Silicon Labs factory default
  VID/PID for multiple interface CP210x devices
- Created a cp210x_port_private struct created for each port on
  startup, this struct holds the interface number
- Added a cp210x_release function to clean up the cp210x_port_private
  memory created on startup
- Modified usb_get_config and usb_set_config to get a pointer to the
  cp210x_port_private struct, and use the interface number there in the
  usb_control_message wIndex param

Subject: [PATCH 3777/6423] Allocate correct size (portably) in
 drivers/usb/gadget/f_midi.c::f_midi_bind()

As the coverity checker puts it:

"Passing argument "sizeof (midi_function) /*8*/" to function "kcalloc"
and then casting the return value to "struct usb_descriptor_header **"
is suspicious. ... In this particular case sizeof(struct
usb_descriptor_header **) happens to be equal to sizeof(struct
usb_descriptor_header *), but this is not a portable assumption."

I believe we really do intend to use 'sizeof(*midi_function)' here, so
this patch makes that change.

Subject: [PATCH 3778/6423] usb/core: remove "always" from usb_unlink_urb()
 kernel doc entry

The kernel doc entry for usb_unlink_urb() contains the phrase "This
request is always asynchronous.". The "always" leads to the assumption
that the ->complete() callback is not called from within
usb_unlink_urb(). This is not true. The HCD is allowed to call the
->complete() from within ->urb_dequeue() if it is appropriate for the
hardware.
This patch updates the kernel doc so usb-device driver authors make sure
to drop all locks (and make sure it is okay to drop them) which are
acquired by the complete callback before calling usb_unlink_urb().

A read from GadgetFS endpoint 0 during the data stage of a control

This patch makes it correctly set the return value to the number of

Date: Thu, 1 Mar 2012 10:51:03 +0100
Subject: [PATCH 3786/6423] staging: iio: core: Introduce debugfs support, add
 support for direct register access

Changes since V1:

Exclude iio debugfs code in case CONFIG_DEBUG_FS isn't enabled.
	Introduce helper function iio_get_debugfs_dentry.
	Document additions to struct iio_dev

iio_debugfs_read_reg:
	Use snprintf.
	Use a shorter fixed length.
	Introduce len instead of pointer math.

iio_debugfs_write_reg:
	Fix return value use PT_ERR.

Changes since V2:

Use debugfs_remove.
Fix whitespace damage.

Subject: [PATCH 3790/6423] Staging: rtl8712/rtl8192u: move USB device ID
 within staging drivers.

It seems the USB device ID 0bda:8192 is wrongly assigned to the
RTL8192SU chip and not to the RTL8191SU chip in the USB database.
So this patch moves this device ID from the rtl8192u staging
driver to the rtl8712 staging driver.

This patch was tested with a Radicom WIFIHU embedded wireless
module with a RTL8191SU chip and the USB device ID 0bda:8192.
Without the patch the rtl8192u driver claims this device, but
it does not work. With the patch the rtl8712 driver services
this device and it works.

 'pstAddIndication' in CmHost.c and removes a whitespace

Memory is being allocated by kmalloc and stored in
variable pstAddIndication.  However, this memory is
not being freed in all cases. Therefore, this patch
frees it on several exit paths. This patch also
removes a whitespace.

Subject: [PATCH 3792/6423] staging: ozwpan: remove debug allocator

The kernel already has a debug allocator, no need to have one unique to
a single driver.  So delete it, replace with kfree, kmalloc, and, in a
few places that need it, kzalloc().

Subject: [PATCH 3793/6423] e100: Fix rx-over-length statistics.

The old code would += the total errors every time
stats were gathered.  Instead, keep a count of short-pkt
and long-pkt counters and then simply add them together
for the rx-over-length stat.

Subject: [PATCH 3795/6423] ixgbe: dcb: check setup_tc return codes

dcb netlink code calls setup_tc to init hardware traffic classes
to use for DCB. At some call sites the return values are not
checked for errors and in one case may return -EINVAL back to
the net/dcbnl.c caller which is expecting a u8.

This fixes some smatch hits and although failures are never
seen in practive its best to check return codes.

Subject: [PATCH 3796/6423] net: dcb: getnumtcs()/setnumtcs() should return an
 int

{g|s}etnumtcs() today returns a u8 that is only used by the DCB code
to verify no error occurred. Today the driver implementations return
negative error codes which end up being non-zero so the logic works
out but triggers some sparse warnings.

To fix the sparse warnings convert the return value to an int.

This replaces an unjustified BUG_ON(), which could get triggered under normal
conditions: X_calc can be 0 when p > 0. X would in this case be set to the
minimum, s/t_mbi. Its replacement avoids t_ipi = 0 (unbounded sending rate).

Thanks to Jordi, Victor and Xavier who reported this.

Subject: [PATCH 3798/6423] dccp: fix bug in sequence number validation during
 connection setup

This fixes a bug in the sequence number validation during the initial handshake.

The code did not treat the initial sequence numbers ISS and ISR as read-only and
did not keep state for GSR and GSS as required by the specification. This causes
problems with retransmissions during the initial handshake, causing the
budding connection to be reset.

This patch now treats ISS/ISR as read-only and tracks GSS/GSR as required.

Subject: [PATCH 3799/6423] regulator: provide a helper for registering a fixed
 regulator

Some devices require a regulator to work, but boards may not have
a software controllable regulator for this device. Provide a helper
function to make it simpler for these boards to register a fixed
regulator as a dummy regulator.

Subject: [PATCH 3803/6423] can: peak_pci: add support of some new PEAK-System
 PCI cards

This patch adds the support of some new PEAK-System PCI cards in the CAN
network sub-system. These are:

PCAN-PCIeC (PCI-ExpressCard)
PCAN-mminiPCI (mini-PCI)
PCAN-PCI (PCI next-gen)

This patch also adds the control of the blinking leds of the PCAN-PCIeC.

Subject: [PATCH 3805/6423] can: usb: PEAK-System Technik USB adapters driver
 core

This patch adds the core of the peak_usb driver which handles PEAK-System
Technik PCAN USB adapters. It defines the parts which are common to the
PCAN-USB adapters: can network interfaces management, network-to/from-usb
data path interface, timestamps management...

Subject: [PATCH 3806/6423] can: usb: PEAK-System Technik PCAN-USB specific
 part

This patch adds the specific part which handles the PCAN-USB adapter from
PEAK-System Technik (http://www.peak-system.com). The PCAN-USB adapter is
a sja1000 based, mono-channel USB 1.1 adapter compliant with CAN
specifications 2.0A (11-bit ID) and 2.0B (29-bit ID).

Subject: [PATCH 3809/6423] udlfb: Make sure to get correct endian keys from
 vendor descriptor

The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen
on big-endian CPUs where the DL chips's max mode was smaller than the
monitor's native mode.

Subject: [PATCH 3810/6423] udlfb: Add module_param to allow forcing
 pixel_limit

Some user scenarios need to prioritize performance over
maxiumum resolution.

Also, some devices may have bad vendor descriptors, and
this allows the user to set a pixel limit that matches
their specific device to avoid blank screens on higher
resolution monitors.

700000 minimum for DL-115, 2360000 maximum for DL-195

It's not necessary for imx-pcm-dma-mx2 to access imx_ssi.dma_params
for burstsize initialization.  Instead, it can just be done in imx-ssi
probe function once.

 machine driver

SND_SOC_AC97_BUS is selected to enable the AC97 support in soc-core.
Rather than selecting the option under SND_IMX_SOC, it's better to
leave the selection to individual machine driver which knows if AC97
support is needed or not.

Subject: [PATCH 3823/6423] ASoC: core: Split the union for CODEC/platform in
 the DAI

There's now core code which falls back to global CODEC operations for
DAI calls that needs to be able to tell if it's dealing with a CPU or
CODEC DAI and given the small number of DAIs in a typical system and
overall memory usage pattern saving a pointer per DAI is really not
worth the effort.

 EasyTouch TP 72037

The Data Modul TP 72037 EasyTouch controller is derived from EGALAX
controller and is capable of detecting dual contacts. Packets can be 5
bytes or 10 bytes long, depending whether one or two contacts are
detected. Format is same as EGALAX touch controller, but with x and y
coordinates inverted.

This fixes reference-before-check problem; there is no reason to check
if caller passed NULL dev or bus_ops as it is done only by bus-specific
drivers which already do the right thing.

Subject: [PATCH 3832/6423] PM / Sleep: Fix possible infinite loop during
 wakeup source destruction
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If wakeup_source_destroy() is called for an active wakeup source that
is never deactivated, it will spin forever.  To prevent that from
happening, make wakeup_source_destroy() call __pm_relax() for the
wakeup source object it is about to free instead of waiting until
it will be deactivated by someone else.  However, for this to work
it also needs to make sure that the timer function will not be
executed after the final __pm_relax(), so make it run
del_timer_sync() on the wakeup source's timer beforehand.

Additionally, update the kerneldoc comment to document the
requirement that __pm_stay_awake() and __pm_wakeup_event() must not
be run in parallel with wakeup_source_destroy().

Date: Fri, 17 Feb 2012 23:39:33 +0100
Subject: [PATCH 3833/6423] PM / Sleep: Fix race conditions related to wakeup
 source timer function
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If __pm_wakeup_event() has been used (with a nonzero timeout) to
report a wakeup event and then __pm_relax() immediately followed by
__pm_stay_awake() is called or __pm_wakeup_event() is called once
again for the same wakeup source object before its timer expires, the
timer function pm_wakeup_timer_fn() may still be run as a result of
the previous __pm_wakeup_event() call.  In either of those cases it
may mistakenly deactivate the wakeup source that has just been
activated.

To prevent that from happening, make wakeup_source_deactivate()
clear the wakeup source's timer_expires field and make
pm_wakeup_timer_fn() check if timer_expires is different from zero
and if it's not in future before calling wakeup_source_deactivate()
(if timer_expires is 0, it means that the timer has just been
deleted and if timer_expires is in future, it means that the timer
has just been rescheduled to a different time).

Subject: [PATCH 3834/6423] PM / Sleep: Make __pm_stay_awake() delete wakeup
 source timers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If __pm_stay_awake() is called after __pm_wakeup_event() for the same
wakep source object before its timer expires, it won't cancel the
timer, so the wakeup source will be deactivated from the timer
function as scheduled by __pm_wakeup_event().  In that case
__pm_stay_awake() doesn't have any effect beyond incrementing
the wakeup source's event_count field, although it should cancel
the timer and make the wakeup source stay active until __pm_relax()
is called for it.

To fix this problem make __pm_stay_awake() delete the wakeup source's
timer and ensure that it won't be deactivated from the timer funtion
afterwards by clearing its timer_expires field.

Subject: [PATCH 3836/6423] PM / Sleep: Add more wakeup source initialization
 routines
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The existing wakeup source initialization routines are not
particularly useful for wakeup sources that aren't created by
wakeup_source_create(), because their users have to open code
filling the objects with zeros and setting their names.  For this
reason, introduce routines that can be used for initializing, for
example, static wakeup source objects.

Subject: [PATCH 3837/6423] PM / Freezer: Remove references to TIF_FREEZE in
 comments

This patch removes all the references in the code about the TIF_FREEZE
flag removed by commit a3201227f803ad7fd43180c5195dbe5a2bf998aa

    freezer: make freezing() test freeze conditions in effect instead of TIF_FREEZE

There still are some references to TIF_FREEZE in
Documentation/power/freezing-of-tasks.txt, but it looks like that
documentation needs more thorough work to reflect how the new
freezer works, and hence merely removing the references to TIF_FREEZE
won't really help. So I have not touched that part in this patch.

Subject: [PATCH 3839/6423] BUG: headers with BUG/BUG_ON etc. need linux/bug.h

If a header file is making use of BUG, BUG_ON, BUILD_BUG_ON, or any
other BUG variant in a static inline (i.e. not in a #define) then
that header really should be including <linux/bug.h> and not just
expecting it to be implicitly present.

We can make this change risk-free, since if the files using these
headers didn't have exposure to linux/bug.h already, they would have
been causing compile failures/warnings.

Subject: [PATCH 3840/6423] bug: consolidate BUILD_BUG_ON with other bug code

The support for BUILD_BUG in linux/kernel.h predates the
addition of linux/bug.h -- with this chunk off separate,
you can run into situations where a person gets a compile
fail even when they've included linux/bug.h, like this:

    CC      lib/string.o
  lib/string.c: In function 'strlcat':
  lib/string.c:225:2: error: implicit declaration of function 'BUILD_BUG_ON'
  make[2]: *** [lib/string.o] Error 1
  $
  $ grep linux/bug.h lib/string.c
  #include <linux/bug.h>
  $

Since the above violates the principle of least surprise, move
the BUG chunks from kernel.h to bug.h so it is all together.

Subject: [PATCH 3841/6423] kernel.h: doesn't explicitly use bug.h, so don't
 include it.

This header isn't using bug.h infrastructure, but due to historical
reasons, it was including it.  Removing it revealed several implicit
dependencies (since kernel.h is everywhere) so we've fixed those 1st
before deploying this change.

 startup

The ColdFire MBAR register that holds the mapping of the peripheral region
on some ColdFire CPUs is configurable. It can be configured at some address
different to that of the bootloader that loaded the kernel. So hard set
the MBAR register mapping at kernel startup time.

Subject: [PATCH 3843/6423] m68knommu: clean up linker script

There is a lot of years of collected cruft in the m68knommu linker script.
Clean it all up and use the well defined linker script support macros.

Support is maintained for building both ROM/FLASH based and RAM based setups.
No major changes to section layouts, though the rodata section is now lumped
in with the read/write data section.

Subject: [PATCH 3844/6423] m68knommu: remove reduntant definitions of _ramvec

The base of the real RAM resident hardware vectors, _ramvec, is declared in
our asm/traps.h. No need to have local declarations spread around in other
files that use this. So remove them.

Subject: [PATCH 3845/6423] m68knommu: make persistent clock code consistent
 with m68k

The read_persistent_clock() code is different on m68knommu, for really no
reason. With a few changes to support function names and some code
re-organization the code can be made the same.

This will make it easier to merge the arch/m68k/kernel/time.c for m68k and
m68knommu in a future patch.

Subject: [PATCH 3846/6423] m68knommu: modify timer init code to make it
 consistent with m68k code

With a few small changes we can make the m68knommu timer init code the
same as the m68k code. By using the mach_sched_init function pointer
and reworking the current timer initializers to keep track of the common
m68k timer_interrupt() handler we end up with almost identical code for
m68knommu.

This will allow us to more easily merge the mmu and non-mmu m68k time.c
in future patches.

Subject: [PATCH 3847/6423] m68knommu: remove unused CONFIG_GENERIC_CMOS_UPDATE
 option

The CONFIG_GENERIC_CMOS_UPDATE switch is always enabled for the non-MMU
m68k case. But the underlying code to support it, update_persistent_clock(),
doesn't end up doing anything on the currently supported non-MMU platforms.
No platforms supply the necessary function support for writing back the RTC.

So lets remove this option and support code. This also brings m68knommu
in line with the m68k, which doesn't enabled this switch either.

Subject: [PATCH 3848/6423] m68k: merge mmu and non-mmu versions of time.c

There is only trivial differences between the mmu time_mm.c and non-mmu
time_no.c files. Merge them back into a single time.c.

Subject: [PATCH 3849/6423] m68k: remove dead timer code

The set_rtc_mmss() function is defined "static inline" but is never used
in this file. Remove it.

Subject: [PATCH 3850/6423] m68k: merge the mmu and non-mmu versions of
 ptrace.c

Most of the code in the non-mmu ptrace_no.c file is the same as the mmu
version ptrace_mm.c. So merge them back into a single file.

Subject: [PATCH 3851/6423] m68k: make support for FPU hardware configurable

The classic m68k code has always supported an FPU (although it may have
been a software emulated one). The non-MMU m68k code has never supported FPU
hardware. To help in merging common code create a configation setting that
signifies if we are builing in FPU support or not.

This switch, CONFIG_FPU, is set as per the current use cases. So it is
always enabled if CONFIG_MMU is set, and disabled otherwise. With a little
extra code it will be possible to disable it on the classic m68k platforms
as well, and to enable it on non-MMU platforms that do have hardware FPU.

Subject: [PATCH 3852/6423] m68k: merge the MMU and non-MMU versions of
 process.c

The MMU and non-MMU varients of the m68k arch process.c code are pretty
much the same. Only a few minor details differ between the two. The
majority of the difference is to deal with having or wanting hardware FPU
support. So merge them back into a single process.c file.

Subject: [PATCH 3853/6423] m68knommu: make 5206 UART platform addressing
 consistent

If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 5206 UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used

Subject: [PATCH 3857/6423] m68knommu: make 5272 UART platform addressing
 consistent

If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 5272 UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)

Subject: [PATCH 3863/6423] m68knommu: make 54xx UART platform addressing
 consistent

If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 54xx UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used

Subject: [PATCH 3871/6423] m68knommu: simplify the 532x UART setup code

Simplify the UART setup code so that it no longer loops for each UART
present. Just make it do all the work it needs in a single function.
This will make the code easier to share when we move to a single set
of platform data for ColdFire UARTs.

 setup code

The ColdFire UART is common to all ColdFire CPU's. No need to duplicate
its platform setup code for every CPU family member. Merge all the setup
code into a single shared file.

Subject: [PATCH 3875/6423] m68knommu: merge common ColdFire UART IRQ setup

Some ColdFire CPU UART hardware modules can configure the IRQ they use.
Currently the same setup code is duplicated in the init code for each of
these ColdFire CPUs. Merge all this code to a single instance.

Subject: [PATCH 3876/6423] m68knommu: make 520x FEC platform addressing
 consistent

If we make all FEC (ethernet) addressing consistent across all ColdFire
family members then we will be able to remove the duplicated plaform data
and use a single setup for all.

So modify the ColdFire 520x FEC addressing so that:

. FECs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used

Subject: [PATCH 3882/6423] m68knommu: merge common ColdFire FEC platform setup
 code

The ColdFire FEC is common to quite a few ColdFire CPUs. No need to duplicate
its platform setup code for every CPU family member that has it. Merge all the
setup code into a single shared file.

Subject: [PATCH 3883/6423] m68knommu: make 520x QSPI platform addressing
 consistent

If we make all QSPI (SPI protocol) addressing consistent across all ColdFire
family members then we will be able to remove the duplicated plaform data
and code and use a single setup for all.

So modify the ColdFire 520x QSPI addressing so that:

. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used
. move chip select definitions (CS) to appropriate header

Subject: [PATCH 3885/6423] m68knommu: make 5249 QSPI platform addressing
 consistent

If we make all QSPI (SPI protocol) addressing consistent across all ColdFire
family members then we will be able to remove the duplicated plaform data
and code and use a single setup for all.

So modify the ColdFire 5249 QSPI addressing so that:

. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used
. move chip select definitions (CS) to appropriate header

Subject: [PATCH 3889/6423] m68knommu: merge common ColdFire QSPI platform
 setup code

The ColdFire QSPI is common to quite a few ColdFire CPUs. No need to duplicate
its platform setup code for every CPU family member that has it. Merge all the
setup code into a single shared file.

This also results in few platforms no longer needing any local platform
setup code. In those cases remove the empty devices array and initcall
code as well.

Subject: [PATCH 3890/6423] m68knommu: clean up init code in ColdFire 523x
 startup

We can move the QSPI init call to the more general config_BSP() code on
the 523x platorm setup code. Then we can remove the initcall code all
together.

We can also remove the un-needed include of mcfuart.h while we are
cleaning up here too.

Also I noticed that we are not calling the fec_init() code here, and we
should be doing that. Put that back in too.

We can move all the init calls in the initcall code into the more general
arch setup code (which is config_BSP() here). That makes the 528x consistent
with other ColdFire CPUs setup cod. It means we can get rif of the initcall
setup here all together.

Subject: [PATCH 3893/6423] m68knommu: move old ColdFire timers init from CPU
 init to timers code

The original ColdFire timer interrupt setup is used by most of the users
of the original ColdFire timer code. But the code is currently duplicated
in each of the ColdFire CPU specific init files. Move it to the timers
code that it is really part of. It is strait forward to make it conditional
on also having the original interrupt engine that it needs.

Subject: [PATCH 3894/6423] m68knommu: factor some common ColdFire cpu reset
 code

A number of the early ColdFire cores use the same code to reset the CPU.
Currently that is duplicated in each of the sub-arch files. Pull out this
common code and use a single copy of it for all CPU types that use it.

Subject: [PATCH 3895/6423] m68knommu: make 523x CPU reset register addressing
 consistent

If we make all MCF_RCR (CPU reset register) addressing consistent across all
ColdFire CPU family members that use it then we will be able to remove the
duplicated copies of the code that use it.

Subject: [PATCH 3898/6423] m68knommu: factor more common ColdFire cpu reset
 code

Most of the more modern ColdFire cores use the same code to reset the CPU
(but it is different to most of the earlier cores). Currently that is
duplicated in each of the sub-arch files. Pull out this common code and
out a single copy of it with the other common reset code.

Subject: [PATCH 3899/6423] tg3: Fix jumbo loopback test on 5719

Loopback on 9K packet fails because the chip has a DMA limit of 4K.  The
loopback test logic uses a single BD for simplicity.  Fix it by reducing
the jumbo packet size to the DMA limit.

Subject: [PATCH 3901/6423] tg3: Fix poor tx performance on 57766 after MTU
 change

GRC reset causes the read DMA engine to go into a mode that breaks up
requests into 256 bytes.  A PHY reset is required to bring it back to
the normal mode.

Subject: [PATCH 3902/6423] ppp: Change copyright notices from ANU to me

This changes the copyright notices on the PPP code that I developed
in the late 1990s from being copyright The Australian National
University to copyright Paul Mackerras.  I can do this as I have an
acknowledgement in writing from the Head of the Computer Science
Department at ANU (where I worked then) that ANU does not claim any
intellectual property in this code.

While I'm at it, change the copyright notice from BSD-style to
GNU GPL like the rest of the kernel.

From bf7daebb9fba540cb8864f435f153678b3e5c171 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Sun, 4 Mar 2012 12:56:04 +0000
Subject: [PATCH 3903/6423] ppp: Move ioctl definitions from if_ppp.h to new
 ppp-ioctl.h

This moves the definitions of the ioctls, constants and structures
relating to the ppp_generic interface to userspace out from if_ppp.h
to a new file, ppp-ioctl.h.  The new file has my copyright since I
designed and implemented the ppp_generic interface in the late 1990s.
None of the contents of this file comes from the original if_ppp.h
published by Carnegie Mellon University.

Of the remainder of if_ppp.h, only the PPP_MTU definition was being
used, and this replaces the uses of it with PPP_MRU (which is identical).
Therefore, this replaces the entire file with the single line

#include <linux/ppp-ioctl.h>

which clearly doesn't contain any CMU code.  Thus I have removed the
CMU copyright notice with its problematic advertising clause, and in
fact since it's only one trivial line I have not added any other
copyright notice.

From 4b32da2bcf1de2b7a196a0e48389d231b4472c36 Mon Sep 17 00:00:00 2001
From: Paul Mackerras <paulus@samba.org>
Date: Sun, 4 Mar 2012 12:56:55 +0000
Subject: [PATCH 3904/6423] ppp: Replace uses of <linux/if_ppp.h> with
 <linux/ppp-ioctl.h>

Since all that include/linux/if_ppp.h does is #include <linux/ppp-ioctl.h>,
this replaces the occurrences of #include <linux/if_ppp.h> with
#include <linux/ppp-ioctl.h>.

It also corrects an error in Documentation/networking/l2tp.txt, where
it referenced include/linux/if_ppp.h as the source of some definitions
that are actually now defined in include/linux/if_pppol2tp.h.

Subject: [PATCH 3905/6423] ucc_geth: separate out rx/tx ring alloc and free
 operations

Factor out the the existing allocation and free operations
so that they can be used individually.

This is to improve code readability, and also to prepare for
possible future changes like better error recovery and more
dynamic configuration (e.g on-the-fly resizing of the rings).

This change represents a straight up relocation of the existing
code into separate routines without changing any of the contained
code itself.  Local variables are relocated as necessary.

Subject: [PATCH 3908/6423] x86/numa: Improve internode cache alignment

Currently cache alignment among nodes in the kernel is still 128
bytes on x86 NUMA machines - we got that X86_INTERNODE_CACHE_SHIFT
default from old P4 processors.

But now most modern x86 CPUs use the same size: 64 bytes from L1 to
last level L3. so let's remove the incorrect setting, and directly
use the L1 cache size to do SMP cache line alignment.

This patch saves some memory space on kernel data, and it also
improves the cache locality of kernel data.

The System.map is quite different with/without this change:

Subject: [PATCH 3909/6423] IB/iser: Free IB connection resources in the proper
 place

We allocate the login dma buffers in iser_verbs.c as part of
alloc_ib_conn_resources(), however we are freeing them in
iser_initiator.c as part of iser_free_rx_descriptors().  This is
needlessly confusing.  We have an alloc_rx_descriptors() and it
doesn't alloc something that the free_rx_descriptors() frees, and we
have an alloc_ib_conn_resources() that allocs something not freed by
free_ib_conn_resources().  Clean that up.

Subject: [PATCH 3910/6423] pinctrl: fix and simplify locking

There are many problems with the current pinctrl locking:

struct pinctrl_dev's gpio_ranges_lock isn't effective;
pinctrl_match_gpio_range() only holds this lock while searching for a gpio
range, but the found range is return and manipulated after releading the
lock. This could allow pinctrl_remove_gpio_range() for that range while it
is in use, and the caller may very well delete the range after removing it,
causing pinctrl code to touch the now-free range object.

Solving this requires the introduction of a higher-level lock, at least
a lock per pin controller, which both gpio range registration and
pinctrl_get()/put() will acquire.

There is missing locking on HW programming; pin controllers may pack the
configuration for different pins/groups/config options/... into one
register, and hence have to read-modify-write the register. This needs to
be protected, but currently isn't. Related, a future change will add a
"complete" op to the pin controller drivers, the idea being that each
state's programming will be programmed into the pinctrl driver followed
by the "complete" call, which may e.g. flush a register cache to HW. For
this to work, it must not be possible to interleave the pinctrl driver
calls for different devices.

As above, solving this requires the introduction of a higher-level lock,
at least a lock per pin controller, which will be held for the duration
of any pinctrl_enable()/disable() call.

However, each pinctrl mapping table entry may affect a different pin
controller if necessary. Hence, with a per-pin-controller lock, almost
any pinctrl API may need to acquire multiple locks, one per controller.
To avoid deadlock, these would need to be acquired in the same order in
all cases. This is extremely difficult to implement in the case of
pinctrl_get(), which doesn't know which pin controllers to lock until it
has parsed the entire mapping table, since it contains somewhat arbitrary
data.

The simplest solution here is to introduce a single lock that covers all
pin controllers at once. This will be acquired by all pinctrl APIs.

This then makes struct pinctrl's mutex irrelevant, since that single lock
will always be held whenever this mutex is currently held.

From 7ecdb16fe63e5b356335ebdc236adfb48cef31e1 Mon Sep 17 00:00:00 2001
From: Stephen Warren <swarren@nvidia.com>
Date: Fri, 2 Mar 2012 13:05:45 -0700
Subject: [PATCH 3911/6423] pinctrl: refactor struct pinctrl handling in core.c
 vs pinmux.c

This change separates two aspects of struct pinctrl:

a) The data representation of the parsed mapping table, into:

   1) The top-level struct pinctrl object, a single entity returned
      by pinctrl_get().

   2) The parsed version of each mapping table entry, struct
      pinctrl_setting, of which there is one per mapping table entry.

b) The code that handles this; the code for (1) above is in core.c, and
   the code to parse/execute each entry in (2) above is in pinmux.c, while
   the iteration over multiple settings is lifted to core.c.

This will allow the following future changes:

1) pinctrl_get() API rework, so that struct pinctrl represents all states
   for the device, and the device can select between them without calling
   put()/get() again.

2) To support that, a struct pinctrl_state object will be inserted into
   the data model between the struct pinctrl and struct pinctrl_setting.

3) The mapping table will be extended to allow specification of pin config
   settings too. To support this, struct pinctrl_setting will be enhanced
   to store either mux settings or config settings, and functions will be
   added to pinconf.c to parse/execute pin configuration settings.

Subject: [PATCH 3912/6423] pinctrl: add usecount to pins for muxing

Multiple mapping table entries could reference the same pin, and hence
"own" it. This would be unusual now that pinctrl_get() represents a single
state for a client device, but in the future when it represents all known
states for a device, this is quite likely. Implement reference counting
for pin ownership to handle this.

Subject: [PATCH 3913/6423] pinctrl: API changes to support multiple states per
 device

The API model is changed from:

p = pinctrl_get(dev, "state1");
pinctrl_enable(p);
...
pinctrl_disable(p);
pinctrl_put(p);
p = pinctrl_get(dev, "state2");
pinctrl_enable(p);
...
pinctrl_disable(p);
pinctrl_put(p);

to this:

p = pinctrl_get(dev);
s1 = pinctrl_lookup_state(p, "state1");
s2 = pinctrl_lookup_state(p, "state2");
pinctrl_select_state(p, s1);
...
pinctrl_select_state(p, s2);
...
pinctrl_put(p);

This allows devices to directly transition between states without
disabling the pin controller programming and put()/get()ing the
configuration data each time. This model will also better suit pinconf
programming, which doesn't have a concept of "disable".

The special-case hogging feature of pin controllers is re-written to use
the regular APIs instead of special-case code. Hence, the pinmux-hogs
debugfs file is removed; see the top-level pinctrl-handles files for
equivalent data.

Subject: [PATCH 3914/6423] pinctrl: enhance mapping table to support pin
 config operations

The pinctrl mapping table can now contain entries to:
* Set the mux function of a pin group
* Apply a set of pin config options to a pin or a group

This allows pinctrl_select_state() to apply pin configs settings as well
as mux settings.

v3: Fix find_pinctrl() to iterate over the correct list.
   s/_MUX_CONFIGS_/_CONFIGS_/ in mapping table macros.
   Fix documentation to use correct mapping table macro.
v2: Added numerous extra PIN_MAP_*() special-case macros.
   Fixed kerneldoc typo. Delete pinctrl_get_pin_id() and
   replace it with pin_get_from_name(). Various minor fixes.
   Updates due to rebase.

+Finally, some devices expect the mapping table to contain certain specific
+named states. When running on hardware that doesn't need any pin controller
+configuration, the mapping table must still contain those named states, in
+order to explicitly indicate that the states were provided and intended to
+be empty. Table entry macro PIN_MAP_DUMMY_STATE serves the purpose of defining
+a named state without causing any pin controller to be programmed:

From ba110d90c08d9676370db9a62792f57ade5b3bbf Mon Sep 17 00:00:00 2001
From: Stephen Warren <swarren@nvidia.com>
Date: Fri, 2 Mar 2012 13:05:49 -0700
Subject: [PATCH 3915/6423] pinctrl: Show selected function and group in
 pinmux-pins debugfs

Until recently, the pinctrl pinmux-pins debugfs file displayed the
selected function for each owned pin. This feature was removed during
restructing in support of recent API rework. This change restoreds this
feature, and also displays the group that the function was selected on,
in case a pin is a member of multiple groups.

Based on work by: Linus Walleij <linus.walleij@linaro.org>

Subject: [PATCH 3916/6423] drm: drop setting vm_file to filp

Talking to Al Viro on irc, we can see no possible reason for doing
this, the upper mmap code does it. The code has been there since
first import into drm tree I can find.

Al tracked down this as a requirement pre 2.3.51 hasn't been needed since.

Subject: [PATCH 3921/6423] wl12xx: set authorized AP on sta_state notification

wl12xx currently looks for AP authorization by registering
a netdev notifier and waiting for the IF_OPER_UP notification,
which is quite cumbersome.

Use the newly introduced sta_state callback (waiting
for assoc -> auth notification) instead, in order to
simplify it.

Subject: [PATCH 3929/6423] ALSA: ice1724 - constrain runtime rates for locked
 internal rate

The driver already defines control "Multi Track Rate Locking" which
locks the card at current rate if switched to internal clock. This patch
limits the runtime rates to this rate only, allowing proper reporting
of the card capabilities, and e.g. automatic rate conversion by the plug
plugin to the currently locked rate.

Subject: [PATCH 3932/6423] GFS2: Eliminate sd_rindex_mutex

Over time, we've slowly eliminated the use of sd_rindex_mutex.
Up to this point, it was only used in two places: function
gfs2_ri_total (which totals the file system size by reading
and parsing the rindex file) and function gfs2_rindex_update
which updates the rgrps in memory. Both of these functions have
the rindex glock to protect them, so the rindex is unnecessary.
Since gfs2_grow writes to the rindex via the meta_fs, the mutex
is in the wrong order according to the normal rules. This patch
eliminates the mutex entirely to avoid the problem.

Subject: [PATCH 3934/6423] GFS2: make sure rgrps are up to date in func
 gfs2_blk2rgrpd

This patch adds a call to gfs2_rindex_update from function gfs2_blk2rgrpd
and removes calls to it that are made redundant by it. The problem is
that a gfs2_grow can add rgrps to the rindex, then put those rgrps into
use, thus rendering the rindex we read in at mount time incomplete.

Subject: [PATCH 3935/6423] IB/iser: Post initial receive buffers before
 sending the final login request

An iser target may send iscsi NO-OP PDUs as soon as it marks the iSER
iSCSI session as fully operative.  This means that there is window
where there are no posted receive buffers on the initiator side, so
it's possible for the iSER RC connection to break because of RNR NAK /
retry errors.  To fix this, rely on the flags bits in the login
request to have FFP (0x3) in the lower nibble as a marker for the
final login request, and post an initial chunk of receive buffers
before sending that login request instead of after getting the login
response.

Subject: [PATCH 3937/6423] xfs: use per-filesystem I/O completion workqueues

The new concurrency managed workqueues are cheap enough that we can create
per-filesystem instead of global workqueues.  This allows us to remove the
trylock or defer scheme on the ilock, which is not helpful once we have
outstanding log reservations until finishing a size update.

Also allow the default concurrency on this workqueues so that I/O completions
blocking on the ilock for one inode do not block process for another inode.

Subject: [PATCH 3938/6423] xfs: do not require an ioend for new EOF
 calculation

Replace xfs_ioend_new_eof with a new inline xfs_new_eof helper that
doesn't require and ioend, and is available also outside of xfs_aops.c.

Also make the code a bit more clear by using a normal if statement
instead of a slightly misleading MIN().

Subject: [PATCH 3939/6423] IB: Use central enum for speed instead of
 hard-coded values

The kernel IB stack uses one enumeration for IB speed, which wasn't
explicitly specified in the verbs header file.  Add that enum, and use
it all over the code.

The IB speed/width notation is also used by iWARP and IBoE HW drivers,
which use the convention of rate = speed * width to advertise their
port link rate.

Subject: [PATCH 3941/6423] IB/ehca: Fix ilog2() compile failure

I'm getting compile failures building this driver, which I narrowed
down to the ilog2 call in ehca_get_max_hwpage_size...

    ERROR: ".____ilog2_NaN" [drivers/infiniband/hw/ehca/ib_ehca.ko]
    undefined!
    make[1]: *** [__modpost] Error 1
    make: *** [modules] Error 2

The use of shca->hca_cap_mr_pgsize is confusing the compiler, and
resulting in the __builtin_constant_p in ilog2 going insane.

I tried making it take the u32 pgsize as an argument and the expansion
of shca->_pgsize in the caller, but that failed as well.

With this patch in place, the driver compiles on my GCC 4.6.2 here.

Subject: [PATCH 3942/6423] mwifiex: handle auto authentication mode correctly

When authentication type is configured to NL80211_AUTHTYPE_AUTOMATIC,
driver tries to connect using open mode. The association is failed
if AP is configured in shared mode.

This patch adds code to try association using shared mode as well if
open mode association fails.

Now since we returned exact error code in association response handler
(instead of -1), corresponding changes are done in
mwifiex_process_cmdresp().

The approach of this change is flawed, as it triggers tx status processing
from more callsites, yet the chips only have one global tx status queue.
Subsequent patches will properly fix the issue that this one tried to address.

I got these information for the open source part of the Broadcom SDK

Subject: [PATCH 3948/6423] ssb: remove 5GHz antenna gain from sprom

There is no 2.4 GHz or 5GHz antenna gain stored in sprom. The sprom
just stores the gain values for antenna 1 and 2 or 1 to 4 for more
recent sprom versions. On old devices antenna 2 was used for 5 GHz wifi.

Subject: [PATCH 3953/6423] bcma: add support for sprom not found on the device

On SoCs the sprom is stored in the nvram in a special partition on the
flash chip. The nvram contains the sprom for the main bus, but
sometimes also for a pci devices using bcma. This patch makes it
possible for the arch code to register a function to fetch the needed
sprom from the nvram and provide it to the bcma code.

Subject: [PATCH 3956/6423] MIPS: BCM47XX: move and extend sprom parsing

Move the sprom parsing from nvram into sprom.c. There are all values
needed for sprom version 1 to 9 read from nvram and there are more
sanity checks added. This is based on the sprom parsing in the open
source part of the Broadcom SDK.

Subject: [PATCH 3957/6423] MIPS: BCM47XX: provide sprom to bcma bus

On SoCs the sprom is often stored in nvram in the flashchip. This patch
registers a sprom fallback callback handler in bcma and provides the
sprom needed for this device.

Subject: [PATCH 3958/6423] mwifiex: correct bitrates advertised to cfg80211

1. Driver and firmware do not support 22Mbps and 72Mbps bitrates.
Remove them from the rate table advertised to cfg80211.

2. First 4 rates from mwifiex_rates table are not valid for
5GHz/A band. Set correct bitrate array's index and no of rates for
ieee80211_supported_band for 5GHz band.

Subject: [PATCH 3960/6423] mwifiex: fix bug in wildcard scan handling

Currently if valid SSID list is provided in scan request, driver
performs specific SSID scan otherwise wildcard scan is chosen.

When wpa_supplicant provides valid SSID list followed by
zero-length SSID for wildcard scan, only specific SSID scan is
performed by driver. Actually driver is expected to do both type
of scanning in this case. The patch fixes this issue.

Also, use SSID list pointer provided by stack directly, instead
of copying SSID's to local structure.

Subject: [PATCH 3964/6423] b43: prevent firmware on bcm5354 from taking over
 wrong GPIO pins

When using the bcm5354 (Soc with integrated LP-PHY Wifi) with a recent
firmware >= 478.104 it runs out of memory after a very short time in
OpenWrt after doing an active scan or any thing else where packages are
send. This was cased by a gpio misconfiguration, the firmware triggered
the GPIO pins used for buttons on some devices and that caused an other
driver (OpenWrt diag) listening for these buttons irqs to send many
messages to the user space.
This patch fixes the bug for my devices (Asus WL-520GU) and makes it
work with firmware 666.2. Now the firmware just uses LED GPIO pin
number 1 and not the button pins any more.

This is the GPIO Pin layout used on my device, see [0].
GPIO pin layout:
pin#    name    type
0       power   led
1       wlan    led
2       reset   button
3       ses     buttom

This is the nvram configuration output of "nvram show |grep gpio"

related nvram configuration:
wl0gpio2=11
wl0gpio3=11
wl0gpio0=11
wl0gpio1=0x02
reset_gpio=2

Subject: [PATCH 3965/6423] {nl,cfg,mac}80211: Implement RSSI threshold for
 mesh peering

Mesh peer links are established only if average rssi of the peer
candidate satisfies the threshold. This is not in 802.11s specification
but was requested by David Fulgham, an open80211s user. This is a way to avoid
marginal peer links with stations that are barely within range.

This patch adds a new mesh configuration parameter, mesh_rssi_threshold. This
feature is supported only for hardwares that report signal in dBm.

Subject: [PATCH 3966/6423] rndis_wlan: integer overflows in
 rndis_wlan_do_link_up_work()

If "offset" is negative then we can get past this check:
	if (offset > CONTROL_BUFFER_SIZE)
Or if we pick a very high "req_ie_len" then we can get around the check:
	if (offset + req_ie_len > CONTROL_BUFFER_SIZE)

I made "resp_ie_len" and "req_ie_len" unsigned.  I don't know if it was
intentional that they were signed in the original.

Subject: [PATCH 3970/6423] rndis_wlan: fix le16/le32_to_cpu mix up with
 config.beacon_period

'beacon_period' in 'struct ndis_80211_conf' is __le32 instead of __le16 so
le32_to_cpu must be used instead of le16_to_cpu.

Also correct 'beacon_interval' variables used for passing this value forward
from u16 to u32 and rename those variables 'beacon_period' This is to avoid
confusion because 'beacon_interval' is defined as __le16 at other structure,
'struct ndis_80211_fixed_ies'.

Subject: [PATCH 3974/6423] mwifiex: endian bug in
 mwifiex_drv_change_adhoc_chan()

In mwifiex_drv_change_adhoc_chan() we pass channel to
mwifiex_bss_ioctl_ibss_channel() which sets the high 16 bits.  This
works on little endian systems but not on big endian ones.  I've changed
mwifiex_drv_change_adhoc_chan() to use a 16 bit variable.  This matches
the other functions in the file.

I considered changing mwifiex_change_adhoc_chan() as well but it turns
out that the function isn't implemented so I just removed the
definition.

Several MAC address comparison functions assume 16 bit alignment for pointers

for the IBSS bssid was off by one, causing a severe performance hit on
architectures without efficient unaligned access (e.g. MIPS).

Subject: [PATCH 3978/6423] RDMA/ucma: Fix AB-BA deadlock

When we destroy a cm_id, we must purge associated events from the
event queue.  If the cm_id is for a listen request, we also purge
corresponding pending connect requests.  This requires destroying
the cm_id's associated with the connect requests by calling
rdma_destroy_id().  rdma_destroy_id() blocks until all outstanding
callbacks have completed.

The issue is that we hold file->mut while purging events from the
event queue.  We also acquire file->mut in our event handler.  Calling
rdma_destroy_id() while holding file->mut can lead to a deadlock,
since the event handler callback cannot acquire file->mut, which
prevents rdma_destroy_id() from completing.

Fix this by moving events to purge from the event queue to a temporary
list.  We can then release file->mut and call rdma_destroy_id()
outside of holding any locks.

Subject: [PATCH 3979/6423] mac80211: use compare_ether_addr on MAC addresses
 instead of memcmp

Because of the constant size and guaranteed 16 bit alignment, the inline
compare_ether_addr function is much cheaper than calling memcmp.

Subject: [PATCH 3981/6423] mac80211: add an rx flag for ignoring a packet's
 signal strength

For A-MPDU rx it makes sense to only process the signal strength once per
aggregate instead of once per subframe. Additonally, some hardware (e.g.
Atheros) only provides valid signal strength information for the last
subframe.

Subject: [PATCH 3982/6423] net: export netdev_stats_to_stats64

Some drivers use internal netdev stats member to store part of their
stats, yet advertize ndo_get_stats64() to implement some 64bit fields.

Allow them to use netdev_stats_to_stats64() helper to make the copy of
netdev stats before they compute their 64bit counters.

Subject: [PATCH 3983/6423] mac80211: fix the support of setting non-forwarding
 entity in Mesh

RANN, PREP and PERR propagation should happen only if the
dot11MeshForwarding is true.  Besides, data frame should not be
forwarded if dot11MeshForwarding is false. This redundant checking
is necessary to avoid the broadcasted ARP breaking the non-forwarding
rule.

Subject: [PATCH 3984/6423] cfg80211: Add an attribute to set inactivity
 timeout in AP mode

This patch adds an attribute, NL80211_ATTR_INACTIVITY_TIMEOUT,
to set the inactivity timeout which can be used to remove the
station in AP mode. This can be passed in NL80211_CMD_START_AP
and used by the drivers which have AP MLME in firmware but
don't support get_station() properly. To disable inactivity
timer in userspace, wpa_s for example, there is a new flag,
NL80211_FEATURE_INACTIVITY_TIMER, in nl80211_feature_flags
through which drivers can register their capability to use
the inactivity timeout to free the stations.

Subject: [PATCH 3985/6423] mac80211: use common radiotap code for cooked
 monitors

There's no need to hardcode a subset of the
radiotap header for cooked monitor receive,
we can just reuse the normal monitor mode
radiotap code. This simplifies the code and
extends the information available on cooked
monitor interfaces.

Subject: [PATCH 3986/6423] mac80211: combine QoS with other BSS changes

When associating and particularly when disassociating
there's no need to notify the driver about changes
with multiple calls to bss_info_changed, we should
combine the QoS enabling/disabling into the same call
as otherwise the driver could get confused about QoS
suddenly getting disabled while connected.

Subject: [PATCH 3987/6423] rtlwifi: Detect misread of end-point count

In the unlikely event of a misread of the USB end point count, the driver
generates a divide fault. To prevent this, add a check of the value
returned by _rtl_usb_init(). In addition, add some logging to indicate
why the condition occurred.

Subject: [PATCH 3988/6423] rtlwifi: Remove extraneous value return

In usb.c, routine _rtl_usb_init_sw() always returns 0, and rtl_usb_probe()
never checks the returned value. Thus we can change _rtl_usb_init_sw() to
a void routine. In addition, remove the underscore at the beginning of the
name of the routine.

Subject: [PATCH 3989/6423] rtlwifi: rtl8192c: Prevent sleeping from invalid
 context in rtl8192cu

When driver rtl8192cu is used with the debug level set to 3 or greater,
the result is "sleeping function called from invalid context" due to
an rcu_read_lock() call in the DM refresh routine in driver rtl8192c.
This lock is not necessary as the USB driver does not use the struct
being protected, thus the lock is set only when a PCI interface is
active.

This bug is reported in https://bugzilla.kernel.org/show_bug.cgi?id=42775.

exposed to the net_device. The usb private statistics counter only
remains with counters for control packets between driver and usb

Subject: [PATCH 3995/6423] brcm80211: smac: remove firmware requests from
 init_module syscall

As indicated in [1] on netdev mailing list drivers should not block
on the init_module() syscall. This patch defers the actual driver
registration to a workqueue so the init_module() syscall can complete
without delay.

Subject: [PATCH 3999/6423] r8169: add byte queue limit support.

Nothing fancy:
- sent bytes count is notified in the start_xmit path right before
  updating the owner bit in the hardware Tx descriptor (E. Dumazet)
- avoid useless tp->dev dereferencing in start_xmit (E. Dumazet)

Use of netdev_reset_queue is favored over proper accounting in
rtl8169_tx_clear_range since the latter would need more work for the
same result (nb: said accounting degenerates to nothing in xmit_frags).

Subject: [PATCH 4002/6423] ASoC: imx: move eukrea audmux call into ASoC
 machine driver

It moves eukrea audmux configuration call from board file into ASoC
machine driver eukrea-tlv320, so that it gets aligned wm1133-ev1 and
mx27vis-aic32x4, and more importantly it will ease the moving of audmux
into sound/soc/imx as a platform driver later.

Subject: [PATCH 4006/6423] ASoC: imx: move audmux driver into sound/soc/imx

As audmux becomes a platform driver and its callers are all ASoC
machine drivers, there is no reason to keep it in arch folder, so
move it to sound/soc/imx.

One bonus point would be those ASoC machine drivers stop including
mach/audmux.h, since it's been moved to sound/soc/imx/imx-audmux.h.
This should be a move to the right direction in terms of single kernel
image goal.

From 4762fbab0b1cf1d4f3e02b78351dc6fa59ca564e Mon Sep 17 00:00:00 2001
From: Shawn Guo <shawn.guo@linaro.org>
Date: Mon, 5 Mar 2012 22:30:55 +0800
Subject: [PATCH 4008/6423] ASoC: imx: separate imx-pcm bits from imx-ssi
 driver

Currently the imx-ssi.c[h] accommodates the imx-pcm common bits which
are shared between imx-pcm-dma-mx2 and imx-pcm-fiq drivers.  It assumes
that imx-pcm-dma-mx2 and imx-pcm-fiq will always be used together with
imx-ssi driver.  However this becomes untrue when we see that driver
sound/soc/fsl/fsl_ssi could possibly work with imx-pcm-dma-mx2 too.

The patch moves the imx-pcm common bits from imx-ssi.c[h] into new
files imx-pcm.c[h], and let imx-pcm-dma-mx2 and imx-pcm-fiq drivers
build it in, so that imx-pcm-dma-mx2 can work with no dependency on
imx-ssi driver.

From 56cea3f1e7db0ccde9e2ac66df2f920c73c419ef Mon Sep 17 00:00:00 2001
From: Shawn Guo <shawn.guo@linaro.org>
Date: Mon, 5 Mar 2012 22:30:56 +0800
Subject: [PATCH 4009/6423] ASoC: imx: add an explicit Kconfig option for
 imx-ssi driver

Currently ASoC:imx uses menuconfig option SND_IMX_SOC selects imx-ssi
driver, and it works because all the machine driver covered by the
menuconfig need to build imx-ssi driver in.  However, it will not work
any more if we have a imx based machine driver going into the menuconfig
while working with fsl_ssi driver (sound/soc/fsl/fsl_ssi.c) rather than
imx-ssi one.

The patch adds an explicit Kconfig option SND_SOC_IMX_SSI for imx-ssi
driver, so that it can be selected independently from the menuconfig
option SND_IMX_SOC.

Subject: [PATCH 4014/6423] 8139too: Add 64bit statistics

Switch to use ndo_get_stats64 to get 64bit statistics.
Two sync entries are used (one for Rx and one for Tx).

-	 * and a data register (MDR, 0xD4).
-	 *
-	 * The MCR (message control register) format is the following:

-	 *   2.  [23:16]: Port
-	 *   3.  [15:8]: Register Offset
-	 *   4.  [7:4]: Byte Enables (use 0xF to set all of these bits
-	 *              to 1)
-	 *   5.  [3:0]: reserved
-	 *
-	 *  Read (0xD0) and write (0xE0) opcodes are written to the
-	 *  control register when reading and writing to Lincroft
-	 *  registers, respectively.
-	 *
-	 *  We're interested in registers found in the Lincroft
-	 *  B-unit.  The B-unit port is 0x3.
-	 *
-	 *  The six B-unit RAR register offsets we use are listed
-	 *  earlier in this file.
-	 *
-	 *  Lastly writing to the MCR register requires the "Byte
-	 *  enables" bits to be set to 1.  This may be achieved by
-	 *  writing 0xF at bit 4.
-	 *
-	 * The MDR (message data register) format is the following:
-	 *   1. [31:0]: Read/Write Data
-	 *
-	 *  Data being read from this register is only available after
-	 *  writing the appropriate control message to the MCR
-	 *  register.
-	 *
-	 *  Data being written to this register must be written before
-	 *  writing the appropriate control message to the MCR

From: Alan Cox <alan@linux.intel.com>
Date: Mon, 5 Mar 2012 15:01:02 -0800
Subject: [PATCH 4017/6423] x86/mid/scu_ipc: Remove Moorestown support

All the production devices use the PC compatible version of this
device so don't use the SCU interfaces or the SCU firmware
interfaces.

Delete lots of code and conditional paths

Subject: [PATCH 4020/6423] x86/mid/thermal: Turn off thermistor

Instead of complaining that the voltage is on, we can just ask
the MSIC to turn the voltage off. This should save some power.

Voltage for thermistors is turned on when ADC conversion is
initiated.

Subject: [PATCH 4021/6423] x86/mid/powerbtn: Use MSIC read/write instead of
 ipc_scu

In the 2.6.36 kernel we did not have the MSIC driver.  Changed
all ipc_scu_reads/writes to use the MSIC driver and defines.
Added a fix from the 2.6.36 kernel where the SCU FW could send a
power button interrupt to the IA32 FW and the kernel was not
running yet.  This resulted in the interrupt not getting cleared
and the power button was ignored.  this fix just clears the
interrupt on start-up.

Subject: [PATCH 4023/6423] x86/geode/net5501: Add platform driver for Soekris
 Engineering net5501

Add platform driver for the Soekris Engineering net5501 single-board
computer.  Probes well-known locations in ROM for BIOS signature
to confirm correct platform.  Registers 1 LED and 1 GPIO-based
button (typically used for soft reset).

Subject: [PATCH 4024/6423] x86/olpc/xo15/sci: Enable lid close wakeup control

Like most systems, OLPC's ACPI LID switch wakes up the system
when the lid is opened, but not when it is closed.

Under OLPC's opportunistic suspend model, the lid may be closed
while the system was oportunistically suspended with the screen
running.  In this event, we want to wake up to turn the screen
off.

Enable control of normal ACPI wakeups through lid close events
through a new sysfs attribute "lid_wake_on_closed".  When set,
and when LID wakeups are enabled through ACPI, the system will
wake up on both open and close lid events.

Subject: [PATCH 4027/6423] openrisc: fix virt_addr_valid

virt_addr_valid() shouldn't be comparing the address to memory_end which is
a phys_addr_t.  Change this to do like other arches and check that the
address falls within a valid page frame.

Subject: [PATCH 4028/6423] openrisc: sanitize use of orig_gpr11

The pt_regs struct had both a 'syscallno' field and an 'orig_gpr11' field
and it wasn't really clear how these were supposed to be used.  This patch
removes the syscallno field altogether and makes orig_gpr11 work more
like other architectures: keep track of syscall number in progress or
hold -1 for non-syscall exceptions.

Subject: [PATCH 4031/6423] pinctrl: add a driver for NVIDIA Tegra

This adds a driver for the Tegra pinmux, and required parameterization
data for Tegra20 and Tegra30.

The driver is initially added with driver name and device tree compatible
value that won't cause this driver to be used. A later change will switch
the pinctrl driver to use the correct values, switch the old pinmux
driver to be disabled, and update all code that uses the old pinmux APIs
to use the new pinctrl APIs.

- * Original Media Tablet 10.6 inch report descriptor.
- *
- * There are at least two versions of this model in the wild. They are
- * represented by Genius G-Pen M609 (older version) and Genius G-Pen M609X
- * (newer version).
- *
- * Both versions have the usual pen with two barrel buttons and two
- * identical wheels with center buttons in the top corners of the tablet
- * base. They also have buttons on the top, between the wheels, for
- * selecting the wheels' functions and wide/standard mode. In the wide mode
- * the whole working surface is sensed, in the standard mode a narrower area
- * is sensed, but the logical report extents remain the same. These modes
- * correspond roughly to 16:9 and 4:3 aspect ratios respectively.
- *
- * The older version has three wheel function buttons ("scroll", "zoom" and
- * "volume") and two separate buttons for wide and standard mode. The newer
- * version has four wheel function buttons (plus "brush") and only one
- * button is used for selecting wide/standard mode. So, the total number of
- * buttons remains the same, but one of the mode buttons is repurposed as a
- * wheels' function button in the newer version.
- *
- * The wheel functions are:
- * scroll   - the wheels act as scroll wheels, the center buttons switch
- *            between vertical and horizontal scrolling;
- * zoom     - the wheels zoom in/out, the buttons supposedly reset to 100%;
- * volume   - the wheels control the sound volume, the buttons mute;
- * brush    - the wheels are supposed to control brush width in a graphics
- *            editor, the buttons do nothing.
- *
- * Below is the newer version's report descriptor. It may very well be that
- * the older version's descriptor is different and thus it won't be
- * supported.
- *
- * The mouse report (ID 1) only uses the wheel field for reporting the tablet
- * wheels' scroll mode. The keyboard report (ID 13) is used to report the
- * wheels' zoom and brush control functions as key presses. The report ID 12
- * is used to report the wheels' volume control functions. The stylus report
- * (ID 16) has the same problems as the Slim Tablet 5.8 inch report has.
- *
- * The rest of the reports are unused, at least in the default configuration.
- * The purpose of the features is unknown.

- * There are at least two versions of this model in the wild. They are

- * (newer version). The hardware difference between these versions is the same
- * as between older and newer versions of Media Tablet 10.6 inch. The report
- * descriptors are identical for both versions.
- *
- * The function, behavior and report descriptor of this tablet is similar to
- * that of Media Tablet 10.6 inch. However, there is one more field (with
- * Consumer AC Pan usage) in the mouse description. Then the tablet X and Y
- * logical extents both get scaled to 0..16383 range (a hardware limit?),
- * which kind of defeats the advertised 4000 LPI resolution, considering the
- * physical extents of 12x7.25 inches. Plus, reports 5, 10 and 255 are used
- * sometimes (while moving the pen) with unknown purpose. Also, the key codes
- * generated for zoom in/out are different.

Subject: [PATCH 4037/6423] video: s3c-fb: Add support EXYNOS5 FIMD

This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5
and adds extended timing control setting.

EXYNOS5 FIMD needs extended setting for video timing control.
Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and
VIDOSDxB registers in order to set timing value for lager resolution.

Also, address offset of VIDTCONx registers is changed from 0x0
to 0x20000, thus variable type should be changed to int type
to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

Subject: [PATCH 4038/6423] OMAPDSS: HDMI: Add M2 divider while calculating
 clkout

While calculating regm and regmf value add using M2 divider in
the equation.
Formula for calculating:
Output clock on digital core domain:
	CLKOUT = (M / (N+1))*CLKINP*(1/M2)
Internal oscillator output clock on internal LDO domain:
	CLKDCOLDO = (M / (N+1))*CLKINP
The current code when allows variable M2 values as input
ignores using M2 divider values in calculation of regm and regmf.
so fix it by using M2 in calculation although the default value for
M2 is 1.

Subject: [PATCH 4040/6423] OMAPDSS: DISPC: Fix FIR coefficients

coef3_M8 had an incorrect phase with 50% more intensity. This resulted in
banding on slightly down/upscaled images. Fixed a rounding error in coef5_M9.

Also removed ARRAY_LEN macro as ARRAY_SIZE is the standard linux one.

 around wait_for_go/vsync functions

If DSS suspends within the functions dss_mgr_wait_for_go(),
dss_mgr_wait_for_go_ovl() or dss_mgr_wait_for_vsync(). It may lose it's clock
and lead to a register access failure.

Request runtime_pm around these functions.

[archit@ti.com: Moved runtime_pm calls to wait_for_go/vsync functions rather
then calling them from omap_dispc_wait_for_irq_interruptible_timeout()]

Subject: [PATCH 4042/6423] OMAPDSS: APPLY: print warning if
 wait_pending_extra_info_updates fails

wait_pending_extra_info_updates() currently does a hacky second check
for extra_info_update_ongoing() at the end of the function to show a
warning if extra_info update is still ongoing. The call to
extra_info_update_ongoing() should really be inside spinlock, but that's
a bit heavy just for verification.

Rather than that, check the return value of the
wait_for_completion_timeout() and print an error if it has timeouted or
returned an error.

Even better would be to return the error value and act on it in the
callers of wait_pending_extra_info_updates. However, it's not clear what
the callers should do in case of an error, as the error should only
happen if there's a bug in the driver or the HW. So we'll just print the
warning for now.

Subject: [PATCH 4050/6423] HID: multitouch: add more eGalax devices

This is a list of devices that should be handled by hid-multitouch.  They all
present the HID usage "Contact ID" and won't be handled by hid-input.  Some of
them have _not_ been tested (though I have their report descriptors), but I've
been guaranted by eeti that they follow the same protocol.  The tested ones are
also blacklisted in hid-core.c.

Subject: [PATCH 4052/6423] usb/gadget/pch_udc: Fix compile error

Greg's e-mail address was old. So, I resend it.

Though I've tested this patch,
http://marc.info/?l=linux-usb&m=132825305710285&w=2,
I've received the following reports.
http://kisskb.ellerman.id.au/kisskb/buildresult/5771890/
http://kisskb.ellerman.id.au/kisskb/buildresult/5771905/

So, I added header file for these symbols.
Using this patch, this compile error must be disappeared.

Subject: [PATCH 4054/6423] NFS: Properly handle the case where the delegation
 is revoked

If we know that the delegation stateid is bad or revoked, we need to
remove that delegation as soon as possible, and then mark all the
stateids that relied on that delegation for recovery. We cannot use
the delegation as part of the recovery process.

Also note that NFSv4.1 uses a different error code (NFS4ERR_DELEG_REVOKED)
to indicate that the delegation was revoked.

Finally, ensure that setlk() and setattr() can both recover safely from
a revoked delegation.

Subject: [PATCH 4055/6423] NFSv4.1: Fix matching of the stateids when
 returning a delegation

nfs41_validate_delegation_stateid is broken if we supply a stateid with
a non-zero sequence id. Instead of trying to match the sequence id,
the function assumes that we always want to error. While this is
true for a delegation callback, it is not true in general.

Also fix a typo in nfs4_callback_recall.

Date: Sun, 4 Mar 2012 18:13:56 -0500
Subject: [PATCH 4056/6423] NFSv4: Further clean-ups of delegation stateid
 validation

Change the name to reflect what we're really doing: testing two
stateids for whether or not they match according the the rules in
RFC3530 and RFC5661.
Move the code from callback_proc.c to nfs4proc.c

From d0b496d2fc08cc51000fcdd9739235d1cab890cd Mon Sep 17 00:00:00 2001
From: Trond Myklebust <Trond.Myklebust@netapp.com>
Date: Sun, 4 Mar 2012 18:13:56 -0500
Subject: [PATCH 4057/6423] NFSv4: Rename encode_stateid() to
 encode_open_stateid()

The current version of encode_stateid really only applies to open stateids.
You can't use it for locks, delegations or layouts.

Subject: [PATCH 4060/6423] NFSv4: Rename nfs4_copy_stateid()

It is really a function for selecting the correct stateid to use in a
read or write situation.

From 2d2f24add1ff903ff8e0ce61c5c05635cc636985 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4062/6423] NFSv4: Simplify the struct nfs4_stateid

Replace the union with the common struct stateid4 as defined in both
RFC3530 and RFC5661. This makes it easier to access the sequence id,
which will again make implementing support for parallel OPEN calls
easier.

From cd93710e8d290711ba2e08e1d1a380013aad667d Mon Sep 17 00:00:00 2001
From: Chuck Lever <chuck.lever@oracle.com>
Date: Fri, 2 Mar 2012 17:14:31 -0500
Subject: [PATCH 4066/6423] NFS: Fix nfs4_verifier memory alignment

Clean up due to code review.

The nfs4_verifier's data field is not guaranteed to be u32-aligned.
Casting an array of chars to a u32 * is considered generally
hazardous.

Fix this by using a __be32 array to generate a verifier's contents,
and then byte-copy the contents into the verifier field.  The contents
of a verifier, for all intents and purposes, are opaque bytes.  Only
local code that generates a verifier need know the actual content and
format.  Everyone else compares the full byte array for exact
equality.

Also, sizeof(nfs4_verifer) is the size of the in-core verifier data
structure, but NFS4_VERIFIER_SIZE is the number of octets in an XDR'd
verifier.  The two are not interchangeable, even if they happen to
have the same value.

Subject: [PATCH 4070/6423] ath6kl: Fix kernel panic while receiving fwlog
 during boot

"ath6kl: Defer wiphy and netdev registration till the end of ath6kl_core_init()"
causes kernel panic by accessing the unallocated debug resources during
boot time. To fix this, split the debug initialization funtion into two,
one initializes the debug resource and the other takes care of debugfs
initialization. When this issue shows up the kernel crash dump would
look like

Subject: [PATCH 4074/6423] sfc: Remove TX completions from adaptive IRQ
 scoring

RX and TX completions on the same event queue are generally not associated
with the same flows.  The inclusion of TX completions in the adaptive IRQ
score is more of a source of noise rather than useful feedback.  Therefore,
do not include them in the score, and adjust the default threshold scores
down.

Subject: [PATCH 4075/6423] sfc: Raise self-test timeouts

IRQ latency can be ridiculously high for various reasons, so our
current timeouts of 100 ms or 10 ms are too short.

Change the IRQ and event tests to use polling loops starting with a
delay of 1 tick and doubling that if necessary up to a maximum total
delay of approximately 1 second.

Raise the loopback packet RX timeout to 1 second.

Subject: [PATCH 4076/6423] sfc: Test all event queues in parallel

In case all event queues are broken for some reason, this means it
will only take about a second to check them all, rather than up to 32
seconds.  This may also speed up testing in the successful case.

Subject: [PATCH 4078/6423] sfc: Run event/IRQ self-test asynchronously when

Generate a test event on each event queue whenever the interface is
brought up, then after 1 second check that we have either handled a
test event or handled another IRQ for each event queue.

From 104a5f3cad8f2f27cadbdf0029400ecd9e17ccc0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4081/6423] Input: max8925_onkey - avoid accessing input device
 too early

Input device must be allocated (but not necessarily registered) before
requesting IRQs, otherwise there is a chance that IRQ handler fires and
tries to reference not yet allocated input device.

Also it makes sense to store relative IRQ numbers in max8925_onkey_info
structure as they are needed in suspend/resume which we expect to be
called more often than probe and remove.

Subject: [PATCH 4085/6423] ASoC: DAPM: Make sure DAPM widget IO ops hold the
 component mutex

Currently not all DAPM widget IO ops are holding their component mutex
(codec or platform). Make sure this is now held for DAPM widget IO operations.

Subject: [PATCH 4087/6423] ath5k: allow AP and mesh mode to operate

This patch allows the possibility of having the mesh point and AP to be operated
simultaneously in one single radio. Previously, mesh point fails to generate the
mesh beacon if virtual AP is created for the same radio.

Subject: [PATCH 4088/6423] rtlwifi: rtl8192ce: Fix loss of receive performance

Driver rtl8192ce when used with the RTL8188CE device would start at about
20 Mbps on a 54 Mbps connection, but quickly drop to 1 Mbps. One of the
symptoms is that the AP would need to retransmit each packet 4 of 5 times
before the driver would acknowledge it. Recovery is possible only by
unloading and reloading the driver. This problem was reported at
https://bugzilla.redhat.com/show_bug.cgi?id=770207.

The problem is due to a missing update of the gain setting.

Subject: [PATCH 4091/6423] iwlwifi: always monitor for stuck queues

If we only monitor while associated, the following
can happen:
 - we're associated, and the queue stuck check
   runs, setting the queue "touch" time to X
 - we disassociate, stopping the monitoring,
   which leaves the time set to X
 - almost 2s later, we associate, and enqueue
   a frame
 - before the frame is transmitted, we monitor
   for stuck queues, and find the time set to
   X, although it is now later than X + 2000ms,
   so we decide that the queue is stuck and
   erroneously restart the device

It happens more with P2P because there we can
go between associated/unassociated frequently.

We should be doing a shift (1 << FLAG_RADIO_DOWN) here before testing
the flag.  As luck would have it, this test works almost correctly.
The current code tests for FLAG_RADIO_OFF instead of FLAG_RADIO_DOWN.

#define FLAG_RADIO_OFF  0       /* User disabling of MAC */
#define FLAG_RADIO_DOWN 1       /* ifup/ifdown disabling of MAC */

doesn't really change anything as the code

Subject: [PATCH 4098/6423] iwlwifi: introduce per-queue locks

Instead of (ab)using the sta_lock, make the
transport layer lock its own TX queue data
structures with a lock per queue. This also
unifies with the cmd queue lock.

Subject: [PATCH 4099/6423] iwlwifi: make sta lock private & BH lock

Now that the transport has its own locking,
there's no need to have the sta_lock in the
shared data. Also, it can be a BH lock as
it's not used from IRQ handlers.

Subject: [PATCH 4101/6423] iwlwifi: remove shared lock

Some data doesn't need protection, some of the
lock places are simply useless, and some data
can be protected with the mutex instead. Thus
the shared lock can be removed by making those
changes.

Subject: [PATCH 4102/6423] iwlwifi: make EXIT_PENDING depend on mac80211

There's no reason to set EXIT_PENDING when we
start removing the module, as mac80211 will
cleanly shut down the device in this case.
Additionally, there's no point in rejecting
commands to the device when we're cleaning up
as that only leads to unwanted errors from
mac80211 being printed, such as
  failed to remove key (...) from hardware (-16)

Subject: [PATCH 4103/6423] iwlwifi: simplify auth/assoc flow

With mac80211 now giving us station information
(via the sta_state callback) before auth/assoc
we can get rid of tx_sync by adding the station
early for the case of managed interfaces. Keep
AP mode actions the same for now.

As we now get the BSSID early, we can also get
rid of iwl_reprogram_ap_sta().

We can still optimise the number of RXONs we
send to the device, but that can be done later.

From a8bceb392a739321ec20d03a91a86ebdde9c07bb Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Mon, 5 Mar 2012 11:24:30 -0800
Subject: [PATCH 4104/6423] iwlwifi: remove per-device debug level

There's no need for the per-device debug
level that we expose in debugfs since the
module parameter is writable in sysfs.

At the same time, simplify code by changing
    iwl_get_debug_level(shrd) & IWL_DL_ISR)
to
    iwl_have_debug_level(IWL_DL_ISR)

Subject: [PATCH 4105/6423] iwlwifi: remove SKU from config

There's no SKU override, we always just use
it from EEPROM. As such, we can remove it
from the config and use it in hw_param only.
Since iwl_eeprom_check_sku() really needs
to fill it in also rename that to
iwl_eeprom_init_hw_params().

Subject: [PATCH 4106/6423] iwlwifi: use valid TX/RX antenna from hw_params

It's not really a good idea to write to the
global static configuration. Use the valid
TX/RX antenna information only from the HW
params struct except in the case where the
values from the config are used to override
the values from the EEPROM.

Subject: [PATCH 4107/6423] iwlwifi: make config const

Writing to the global config structures
is always wrong. To protect against such
mistakes in the future, mark them const.

The code in the two branches of the #ifdef
is almost the same so move the common code
outside the #ifdef.

Subject: [PATCH 4109/6423] iwlwifi: clean up (wowlan) suspend flow

In the WoWLAN suspend flow, instead of accessing
registers directly, ask the transport to do the
required setup at the end of suspend. If the
transport doesn't implement this, don't tell the
stack we support WoWLAN.

When the device suspends w/o WoWLAN, mac80211
will have stopped it already, which has already
called iwl_apm_stop() via stop_hw(). Thus, it
isn't necessary to call it again in pcie_suspend
and we can simply do nothing there.

This unifies the regular and WoWLAN suspend.

Subject: [PATCH 4110/6423] iwlwifi: move wowlan bool into priv

With the new WoWLAN flow into the transport
there no longer is a need for this to be
shared, so move it into priv.

Subject: [PATCH 4111/6423] iwlwifi: use ieee80211_tx_status

We currently use the _irqsafe version, but that
isn't recommended together with ieee80211_rx()
as it can cause races. If the device reports
a TX-status and RX in that order then with the
current combination mac80211 might process them
in the other order, which can cause issues with
powersaving clients.

Use ieee80211_tx_status() to avoid this race.
Since we don't want to call it with locks held,
process the frame queues later -- this is fine
as they are on the stack.

Subject: [PATCH 4112/6423] iwlwifi: pass response packet directly

When CMD_WANT_SKB is set for a (synchronous)
command, the response is passed back to the
caller which is then responsible for freeing
it. Make this more abstract with real API,
passing directly the response packet in the
new cmd.resp_pkt member and also introduce
iwl_free_resp() to free the pages -- this
way the upper layers don't have to directly
touch the page implementation.

NOTE: This breaks IDI -- the new code isn't reflected there yet!

Subject: [PATCH 4113/6423] iwlwifi: don't pass iwl_rx_mem_buffer to upper
 layers

struct iwl_rx_mem_buffer implementation details
(DMA address, list pointers) that the upper
layers don't need. Introduce iwl_rx_cmd_buffer
that is passed upstream and only contains the
needed data (the page). Additionally, access
this data only via accessor functions, allowing
us to change the implementation in the future.
These accessors are rxb_addr() (as before) and
rxb_steal_page() to take ownership of the data.

Subject: [PATCH 4117/6423] iwlwifi: iwl_rx_cmd_buffer belongs to transport API

This is how the transport passes things
up into higher layers, so it belongs to
the transport API.

Subject: [PATCH 4118/6423] iwlwifi: move tid_to_ac to PCI-E

Currently, queue mapping is handled in the
transport. This may change, but until then
the code for it can be close to where it's
used rather than in iwl-shared.h.

Subject: [PATCH 4121/6423] iwlwifi: fix station HT parameters

My patch "iwlwifi: simplify auth/assoc flow"
caused a serious throughput degradation due
to me forgetting that there are HT settings
in the station table. To restore throughput,
set these parameters correctly when the sta
moves to assoc state.

This patch should probably be merged with
the auth/assoc redesign patch for upstream.
In that case, this paragraph should be added
to the commit log as the third paragraph
(before talking about RXON):

However, as we only get the station HT data
when the station moves into assoc state, we
also need to program this into the device
(and copy it into our database) then.

This shouldn't be in the op_mode, as it
will later be switchable at runtime.

Subject: [PATCH 4124/6423] iwlwifi: move firmware request into drv

Firmware request is a base driver flow,
it isn't related to any specific mode.
Move the code related to it into the
base driver file iwl-drv.c.

Airtime link metric estimation was broken in HT mesh, use
cfg80211_calculate_bitrate to get the right rate value.

Also factor out tx rate copying from sta_set_sinfo().

Subject: [PATCH 4128/6423] mac80211_hwsim: Add tsf to beacons, probe responses
 and radiotap header.

Generate a tsf from internal kernel clock.  Prepare the path for having
different tsf offsets on each phy.  This will be useful for testing
mesh synchronization algorithms.

Subject: [PATCH 4130/6423] ath5k: do not stop queues for full calibration

Some calibration types interfere with tx activity, but the queue stop does
not prevent that. In fact, some calibration types need tx activity to properly
function, so stopping the queues for them is counterproductive.
In some tests this patch has been shown to improve stability, especially in
AP or ad-hoc mode.

Subject: [PATCH 4131/6423] ath5k: do not re-run AGC calibration periodically

All other Atheros drivers run the AGC gain calibration and DC offset
calibration only after reset. Running them periodically has caused stability
issues on some (primarily AR2315/2413/5413/5414 based) devices, leading to
messages such as:

ath5k phy0: gain calibration timeout (2462MHz)
ath5k phy0: calibration of channel 11 failed

When not SPROM is available a fallback mechanism is used. However,
when that fails the code currently continues. This patch assures
that the bcma_sprom_get() function aborts when that happens.

Subject: [PATCH 4133/6423] bcma: add support for on-chip OTP memory used for
 SPROM storage

Wireless Broadcom chips can have either their SPROM data stored
on either external SPROM or on-chip OTP memory. Both are accessed
through the same register space. This patch adds support for the
on-chip OTP memory.

Tested with:
BCM43224 OTP and SPROM
BCM4331 SPROM
BCM4313 OTP

This patch is in response to linux-wireless thread [1].

Subject: [PATCH 4149/6423] NFC: Unlink LLCP child sockets from
 llcp_sock_release

The parent socket (the bound one) could be freed before its children, so
we should unlink the children without trying to reach it through the parent.

We just don't do anything with it when parsing the general bytes.
We handle it from the CONNECT reception code.

Subject: [PATCH 4151/6423] NFC: Remove the rf mode parameter from the DEP link
 up routine

When calling nfc_dep_link_up, we implicitely are in initiator mode.
Which means we also can provide the general bytes as a function argument,
as all drivers will eventually request them.

Subject: [PATCH 4152/6423] NFC: Fix LLCP sockets releasing path

The socket local pointer needs to be set to NULL when the adapter is
removed or the MAC goes down.
If the socket release code is called after such an event, the socket
reference count still needs to be decreased in order for the socket to
eventually be freed.

Subject: [PATCH 4157/6423] net/mlx4_en: Saving mem access on data path

Localized the pdev->dev, and using dma_map instead of pci_map
There are multiple map/unmap operations on data path,
optimizing those by saving redundant pointer access.
Those places were identified as hot-spots when running kernel profiling
during some benchmarks.
The fixes had most impact when testing packet rate with small packets,
reducing several % from CPU load, and in some case being the difference
between reaching wire speed or being CPU bound.

Fix sparse warnings on incompatibility between the endianess of the ctrl_flags
field of struct mlx4_en_priv to the srcrb_flags field of struct
mlx4_wqe_ctrl_seg by changing the former to be __be32 instead of u32.

Subject: [PATCH 4160/6423] net/mlx4: fix sparse warnings on wrong type for RSS
 keys

The keys used for the hardware RSS topelitz hash are of type __be32
where the values provided by the driver are from array of u32,
this triggered sparse warning on incorrect type in assignment as of different base types.
Since these values are picked randomly,
the fix is to transform the key to __be32 by executing cpu_to_be_32()

the mlx4_en module (were originally part of mlx4_en).
Their declaration remained in mlx4_en module, moving the declaration to the right location.

Subject: [PATCH 4169/6423] pinctrl: split pincontrol states into its own
 header

Move the pin control state defines into its own header file,
since it is used both by machine.h which is facing the platform
and by consumer.h which is facing the drivers, and pinctrl.h
which is pinctrl-driver internal, let's not have each and every
.h file include all others, then isolation is moot.

Subject: [PATCH 4172/6423] mlx4_core: Get rid of redundant ext_port_cap flags

While doing the work for commit a6f7feae6d ("IB/mlx4: pass SMP
vendor-specific attribute MADs to firmware") we realized that the
firmware would respond on all sorts of vendor-specific MADs.
Therefore commit 97285b7817 ("mlx4_core: Add extended port
capabilities support") adds redundant code into the driver, since
there's no real reaon to maintain the extended capabilities of the
port, as they can be queried on demand (e.g the FDR10 capability).

This patch reverts commit 97285b7817 and removes the check for
extended caps from the mlx4_ib driver port query flow.

Subject: [PATCH 4177/6423] powerpc/atomic: Implement atomic*_inc_not_zero

Implement atomic_inc_not_zero and atomic64_inc_not_zero. At the
moment we use atomic*_add_unless which requires us to put 0 and
1 constants into registers. We can also avoid a subtract by
saving the original value in a second temporary.

This removes 3 instructions from fget:

- c0000000001b63c0:       39 00 00 00     li      r8,0
- c0000000001b63c4:       39 40 00 01     li      r10,1
...
- c0000000001b63e8:       7c 0a 00 50     subf    r0,r10,r0

Subject: [PATCH 4178/6423] powerpc/icswx: Fix race condition with IPI setting
 ACOP

There is a race where a thread causes a coprocessor type to be valid
in its own ACOP _and_ in the current context, but it does not
propagate to the ACOP register of other threads in time for them to
use it.  The original code tries to solve this by sending an IPI to
all threads on the system, which is heavy handed, but unfortunately
still provides a window where the icswx is issued by other threads and
the ACOP is not up to date.

This patch detects that the ACOP DSI fault was a "false positive" and
syncs the ACOP and causes the icswx to be replayed.

Subject: [PATCH 4180/6423] powerpc: Use set_current_blocked() and
 block_sigmask()

As described in e6fa16ab ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block
is pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures. In the past some architectures got this
code wrong, so using this helper function should stop that from
happening again.

On a 16TB system (using AMS/CMO), I get:

WARNING: ignoring large property [/ibm,dynamic-reconfiguration-memory] ibm,dynamic-memory length 0x000000000017ffec

and significantly less memory is thus shown to the partition. As far as
I can tell, the constant used is arbitrary. Ben Herrenschmidt provided
additional background that

> The limit was originally set because of Apple machines carrying ROM
> images in the device-tree, at a time where we were much more memory
> constrained than we are now.

and that it is likely not very useful any longer.

Subject: [PATCH 4182/6423] powerpc: Make SPARSE_IRQ required

All IRQs on powerpc are managed via irq_domain anyway, there isn't really
any advantage to turning SPARSE_IRQ off, and it's the direction we want
to take the kernel design anyway.  This patch makes powerpc always use
SPARSE_IRQ.

On pseries_defconfig, SPARSE_IRQ adds only about 0x300 bytes to the
.text sections, and removes about 0x20000 from the data section for the
static irq_desc table.

  It is faster than looping for each byte.

- Use memcmp to compare memory areas

Subject: [PATCH 4184/6423] ath6kl: Add provision to define suspend policy in
 disconnected state.

It gives flexibility to the user to define suspend policy
when the suspend mode is set to WOW and the device is in
disconnected state at the time of suspend.

New module parameter wow_mode is added to get the choice
from the user. This parameter is valid only if the module
parameter suspend_mode is set to WOW.

To force WOW in connected state and cut power
in disconnected state:
  suspend_mode=0x3 wow_mode=0x1

To force WOW in connected state and deep sleep
in disconnected state (this is also the default wow_mode):
   suspend_mode=0x3 wow_mode=0x2

If there is no value specified to wow_mode during insmod,
deep sleep mode will be tried in the disconnected state.

Subject: [PATCH 4185/6423] ath6kl: Check wow state before sending control and
 data pkt

Below two scenarios are taken care in this patch which helped
to fix the firmware crash during wow suspend/resume.

* TX operation (ctrl tx and data tx) has to be controlled based
  on suspend state. i.e, with respect to WOW mode, control packets
  are allowed to send from the host until the suspend state goes
  ATH6KL_STATE_WOW and the data packets are allowed until WOW
  suspend operation starts.

* Similarly, wow resume is NOT allowed if WOW suspend is in progress.

Subject: [PATCH 4186/6423] ath6kl: Maintain the listen interval per VIF
 specific

Firmware has the option to support the listen interval
per vif specific. Fix this.

Listen interval can be set by the TUs or by the number
of beacons. Current code enables the user to configure
the listen interval in the unit of 'number of beacons'
using debugfs entry "listen_interval". Going forward,
we need to alter the listen interval in the unit of TUs
to get good power numbers while going to WOW suspend/resume.

Allowing the user to change the listen interval in
the unit of "number of beacons"  in debugfs and changing
listen interval in wow suspend/resume in the unit of
time (TUs) would lead us to confuse.

This patch make sures the listen interval is changed only
in the unit of time (TUs).

Subject: [PATCH 4187/6423] ath6kl: Set optimal listen intvl,bmiss,scan params
 while going to wow suspend

* In order to save the target power in WOW suspend state,
  configure the best optimal values for the below parameters,
     - listen interval.
     - beacon miss interval.
     - scan parameters.

  Default values for above attributes are reverted in
  wow resume operation.

* The default listen interval is set before the host issue
  connect request.

* New function is added to configure beacon miss count.

kvalo: minor changes to fix open parenthesis alignment

Subject: [PATCH 4188/6423] ALSA: hda/realtek - Reuse init_hook for ALC269VB
 coef setup

Move the currently unused spec->init_hook at the beginning of the init
sequence so that the recently added ALC269VB coef setup can be put
there.  The alc_init() is again clean without an ugly check.

Fix this by using ACCESS_ONCE() instead of rcu_dereference_check_mce()
over mcelog.next. Since the access to each entry is controlled by the
->finished field, ACCESS_ONCE() should work just fine. An rcu_dereference
is unnecessary here.

Subject: [PATCH 4191/6423] ALSA: hda - Set codec to D3 forcibly even if not
 used

We've seen a problem with a pop-noise at suspend/resume on a HP
machine with ALC269, and it turned out to be an issue that the
controller going to D3 while the codec is unused.

When the device is once suspended and resumed and kept unused, the
driver doesn't initialize the codecs.  Instead, the codec chips are
set up dynamically at the first usage.  Now, suppose the device going
to suspend again before the codec is set up.  The controller is turned
off to D3 while the codec chips are untouched.  This caused a pop
noise because the codec chip might have been turned on implicitly by
the hardware.

As a workaround, the codec chip needs to be set to D3 when going to
suspend no matter whether it was used or not.  Also, for making it
happening, the controller has to be always set up in the resume path.

Subject: [PATCH 4192/6423] ASoC: dapm: Only lock CODEC for I/O if not using
 regmap

If we do use regmap then regmap will take care of things for us. We
actually already have this check at a higher level for the current
users but this makes sure we do the right thing in the future too if
we need to.

Subject: [PATCH 4193/6423] drm: cope with platformdev->id == -1

If there are not multiple instances of a platform device, the id
should apparently be set to -1.  Which results in a odd looking
bus-id like "platform:foodrm:-1".  Probably we should just treat
this case as id 0.

From c15f1c83251049182b1771da004d14f29683ab97 Mon Sep 17 00:00:00 2001
From: Jan Engelhardt <jengelh@medozas.de>
Date: Tue, 14 Feb 2012 00:24:10 +0100
Subject: [PATCH 4203/6423] netfilter: ipset: use NFPROTO_ constants

ipset is actually using NFPROTO values rather than AF (xt_set passes
that along).

Subject: [PATCH 4206/6423] netfilter: ipset: Exceptions support added to
 hash:*net* types

The "nomatch" keyword and option is added to the hash:*net* types,
by which one can add exception entries to sets. Example:

        ipset create test hash:net
        ipset add test 192.168.0/24
        ipset add test 192.168.0/30 nomatch

In this case the IP addresses from 192.168.0/24 except 192.168.0/30
match the elements of the set.

From 544d5c7d9f4d1ec4f170bc5bcc522012cb7704bc Mon Sep 17 00:00:00 2001

Date: Sun, 5 Feb 2012 03:44:51 +0100
Subject: [PATCH 4211/6423] netfilter: ctnetlink: allow to set expectfn for
 expectations

This patch allows you to set expectfn which is specifically used
by the NAT side of most of the existing conntrack helpers.

I have added a symbol map that uses a string as key to look up for
the function that is attached to the expectation object. This is
the best solution I came out with to solve this issue.

Subject: [PATCH 4216/6423] netfilter: xt_LOG: fix bogus extra layer-4 logging
 information

In 16059b5 netfilter: merge ipt_LOG and ip6_LOG into xt_LOG, we have
merged ipt_LOG and ip6t_LOG.

However:

IN=wlan0 OUT= MAC=xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx
SRC=213.150.61.61 DST=192.168.1.133 LEN=40 TOS=0x00 PREC=0x00 TTL=117
ID=10539 DF PROTO=TCP SPT=80 DPT=49013 WINDOW=0 RES=0x00 ACK RST
URGP=0 PROTO=UDPLITE SPT=80 DPT=49013 LEN=45843 PROTO=ICMP TYPE=0
       ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Several missing break in the code led to including bogus layer-4
information. This patch fixes this problem.

Subject: [PATCH 4221/6423] netfilter: nf_conntrack: pass timeout array to
 l4->new and l4->packet

This patch defines a new interface for l4 protocol trackers:

unsigned int *(*get_timeouts)(struct net *net);

that is used to return the array of unsigned int that contains
the timeouts that will be applied for this flow. This is passed
to the l4proto->new(...) and l4proto->packet(...) functions to
specify the timeout policy.

This interface allows per-net global timeout configuration
(although only DCCP supports this by now) and it will allow
custom custom timeout configuration by means of follow-up
patches.

From 50978462300f74dc48aea4a38471cb69bdf741a5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4222/6423] netfilter: add cttimeout infrastructure for fine
 timeout tuning

This patch adds the infrastructure to add fine timeout tuning
over nfnetlink. Now you can use the NFNL_SUBSYS_CTNETLINK_TIMEOUT
subsystem to create/delete/dump timeout objects that contain some
specific timeout policy for one flow.

The follow up patches will allow you attach timeout policy object
to conntrack via the CT target and the conntrack extension
infrastructure.

From: Pablo Neira Ayuso <pablo@netfilter.org>
Date: Tue, 28 Feb 2012 23:36:48 +0100
Subject: [PATCH 4223/6423] netfilter: nf_ct_ext: add timeout extension

This patch adds the timeout extension, which allows you to attach
specific timeout policies to flows.

This extension is only used by the template conntrack.

Subject: [PATCH 4224/6423] netfilter: xt_CT: allow to attach timeout policy +
 glue code

This patch allows you to attach the timeout policy via the
CT target, it adds a new revision of the target to ensure
backward compatibility. Moreover, it also contains the glue
code to stick the timeout object defined via nfnetlink_cttimeout
to the given flow.

Example usage (it requires installing the nfct tool and
libnetfilter_cttimeout):

1) create the timeout policy:

 nfct timeout add tcp-policy0 inet tcp \
	established 1000 close 10 time_wait 10 last_ack 10

2) attach the timeout policy to the packet:

 iptables -I PREROUTING -t raw -p tcp -j CT --timeout tcp-policy0

You have to install the following user-space software:

a) libnetfilter_cttimeout:
   git://git.netfilter.org/libnetfilter_cttimeout

b) nfct:
   git://git.netfilter.org/nfct

You also have to get iptables with -j CT --timeout support.

Subject: [PATCH 4228/6423] ath6kl: alignment should match open parenthesis

Fix the issues which checkpatch found and were easy to fix. Especially
callers of ath6kl_bmi_write() are tricky and that needs to be fixed
separately.

Subject: [PATCH 4231/6423] ath6kl: add ath6kl_bmi_write_hi32()

We have a lot of 32 bit writes to the host interest area and the code
doing that is ugly. Clean that up by adding ath6kl_bmi_write_hi32().

This also fixes few checkpatch warnings.

Subject: [PATCH 4233/6423] ath6kl: fix error handling
 ath6kl_target_config_wlan_params()

The error handling in ath6kl_target_config_wlan_params() was just weird,
fix that. This also fixes some of the open parenthesis alignment issues
reported by checkpatch.

Subject: [PATCH 4238/6423] i2c: tegra: Remove unnecessary write to INT_STATUS

The write is not necessary and may cause the I2C controller to misbehave.
With this fix, I2C on Tegra30 works (at least, running i2cdump repeatedly
on the WM8903 on Cardhu's I2C5/DVC bus).

Subject: [PATCH 4239/6423] i2c: add CSR SiRFprimaII on-chip I2C controllers
 driver
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SiRFprimaII is the latest generation application processor from CSR’s
multi-function SoC product family.
The SoC support codes are in arch/arm/mach-prima2 from Linux mainline
3.0.
There are two I2C controllers on primaII, features include:
* Two I2C controller modules are on chip
* RISC I/O bus read write register
* Up to 16 bytes data buffer for issuing commands and writing data
  at the same time
* Up to 16 commands, and receiving read data 16 bytes at a time
* Error INT report (ACK check)
* No-ACK bus protocols (SCCB bus protocols)

+- reg: physical base address of the controller and length of memory mapped

+- interrupts: interrupt number to the cpu.
+
+Optional properties:
+- clock-frequency : Constains desired I2C/HS-I2C bus clock frequency in Hz.
+  The absence of the propoerty indicates the default frequency 100 kHz.

Subject: [PATCH 4241/6423] i2c-s3c2410: Add stub runtime power management

Add stub runtime_pm calls which go through the flow of enabling and
disabling but don't actually do anything with the device itself as
there's nothing useful we can do. This provides the core PM framework
with information about when the device is idle, enabling chip wide
power savings.

Subject: [PATCH 4242/6423] i2c-eg20t: Rework pch_i2c_wait_for_bus_idle to
 reduce wait time

If you insert several i2c transfers, the driver might start the next one
while the STOP bit of the previous transfer is still on the bus, marking
the bus as busy.
pch_i2c_wait_for_bus_idle does an msleep(20) delaying the next transfer
by >=20ms. Reduce wait time by actively waiting 5 us once, then using
usleep_range.

Subject: [PATCH 4245/6423] mac80211: Filter duplicate IE ids

mac80211 is lenient with respect to reception of corrupted beacons.
Even if the frame is corrupted as a whole, the available IE elements
are still passed back and accepted, sometimes replacing legitimate
data.  It is unknown to what extent this "feature" is made use of,
but it is clear that in some cases, this is detrimental.  One such
case is reported in http://crosbug.com/26832 where an AP corrupts
its beacons but not its probe responses.

One approach would be to completely reject frames with invaid data
(for example, if the last tag extends beyond the end of the enclosing
PDU).  The enclosed approach is much more conservative: we simply
prevent later IEs from overwriting the state from previous ones.
This approach hopes that there might be some salient data in the
IE stream before the corruption, and seeks to at least prevent that
data from being overwritten.  This approach will fix the case above.

Further, we flag element structures that contain data we think might
be corrupted, so that as we fill the mac80211 BSS structure, we try
not to replace data from an un-corrupted probe response with that
of a corrupted beacon, for example.

Short of any statistics gathering in the various forms of AP breakage,
it's not possible to ascertain the side effects of more stringent
discarding of data.

Subject: [PATCH 4247/6423] ath9k: make MAC sample statistics optional

They're more expensive than some of the other debug options and only used
in very rare situations, so it sometimes makes sense to disable them while
leaving in debugfs support.

Subject: [PATCH 4248/6423] ath9k: remove rssi/antenna information from recv
 debug stats

The way this is implemented (simply storing the last value) is absolutely
worthless for debugging anything, and the same information is also available
through the MAC sample feature, so there's no point in keeping this around.

Date: Sat, 3 Mar 2012 15:17:06 +0100
Subject: [PATCH 4250/6423] ath9k: fix signal strength reporting issues

On A-MPDU frames, the hardware only reports valid signal strength data for
the last subframe. The driver also mangled rx_stats->rs_rssi using the
ATH_EP_RND macro in a way that may make sense for ANI, but definitely
not for reporting to mac80211.
This patch changes the code to calculate the signal strength from the rssi
directly instead of taking the average value, and flag everything but
the last subframe in an A-MPDU to tell mac80211 to ignore the signal strength
entirely, fixing signal strength fluctuation issues reported by various
users.

Subject: [PATCH 4252/6423] iwlwifi: move ucode loading to op_mode

uCode loading belongs to the op_mode, as it
is dependent on various things there and the
commands sent during it are specific to it.
Move the prototypes to iwl-agn.h to indicate
this. To make this possible, also move all
the calibration handling (which is op_mode
dependent after all).

From 0692fe41b36159be5d8c7d4eef0699e79c383c85 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:37 -0800
Subject: [PATCH 4253/6423] iwlwifi: split out firmware store

Through the driver, struct iwl_fw will
store the firmware. Split this out into
a separate file, iwl-fw.h, and make all
other code use it. To do this, also move
the log pointers into it, and remove the
knowledge of "nic" from everything.

Now the op_mode has a fw pointer, and
(unfortunately) for now the shared data
also needs to keep one for the transport
to access dump the error log -- I think
that will move later.

Since I wanted to constify the firmware
pointers, some more changes were needed.

From 965974a631756ab2729469b9ecadfe61ee44dfc5 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:38 -0800
Subject: [PATCH 4254/6423] iwlwifi: remove iwl-wifi.h

This file was recently introduced, but then
directly abused -- it contained private data
that shouldn't have been used by anything
but the implementation of firmware requests
and some very core code. Now that it is no
longer accessed by any code but the code in
iwl-drv.c, we can dissolve it.

Also rename the iwl_nic struct to iwl_drv to
better reflect where and how it is used.

From e10a0533a9172471b52bd9512838d766420a3baf Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:39 -0800
Subject: [PATCH 4255/6423] iwlwifi: add wrappers for command sending

Add wrappers to send commands from the DVM
op-mode (which essentially consists of the
current driver). This will allow us to move
specific sanity checks there.

Also, this removes iwl_trans_send_cmd_pdu()
since that can now be taken care of in the
DVM-specific wrapper.

Subject: [PATCH 4256/6423] iwlwifi: move RF/CT kill check to command wrapper

Currently, we cannot send any commands when the
uCode is in RF or CT kill, but that will not be
true for all new uCode versions, so we need to
move the check into the uCode specific code.

Also remove the duplicate rfkill check.

Subject: [PATCH 4257/6423] iwlwifi: move lockdep assertion into DVM

The fact that the mutex must be held is an
implementation detail of DVM, but something
has to ensure that no two synchronous cmds
are submitted concurrently. Move the lockdep
assertion into the DVM-specific code, but
also make the transport abort if there are
two concurrently commands.

The assertion is much more useful though as
the transport check can only catch it when
it actually happens, while the assertion
makes sure it can't possibly happen.

Subject: [PATCH 4259/6423] iwlwifi: move rfkill status handling out of
 transport

The transport layer should only check the
hardware RF kill status, not impose any
policy or reaction based on it, so move
that out of it into the op_mode.

For now keep the restriction on loading
firmware, that will have to be removed
later.

Subject: [PATCH 4261/6423] iwlwifi: remove AMT check from transport

As iwl_prepare_card_hw() is idempotent (and
many cards support AMT anyway) there's no
point in calling iwl_prepare_card_hw() only
for AMT capable devices -- call it always
and simplify the code that way.

that will never change, we can access it from

From 6c1011e1918be17f7f8ccca5442cd517f9c29d17 Mon Sep 17 00:00:00 2001
From: Johannes Berg <johannes.berg@intel.com>
Date: Tue, 6 Mar 2012 13:30:48 -0800
Subject: [PATCH 4264/6423] iwlwifi: make tracing use device as identifier

Tracing used the priv pointer as an identifier,
which has the problem that we don't have it in
all code, and also some people say no pointers
should be "leaked" to userspace.

Use the device name instead, it is more useful
anyway.

Subject: [PATCH 4265/6423] iwlwifi: virtualize command queue full behaviour

When the command queue is full, the transport
will return -ENOSPC, but the reaction to that
depends on the op_mode. Virtualize that, the
DVM op_mode checks for CT-kill and restarts
the hardware otherwise.

We may be able to get rid of this callback by
putting the behaviour check into the wrapper
but that needs more careful evaluation.

Subject: [PATCH 4267/6423] iwlwifi: remove num_of_queues module parameter

This is a hardware parameter, so it shouldn't
be configurable by the user. Users can disable
aggregation (which is the only thing affected)
with 11n_disable.

Subject: [PATCH 4273/6423] iwlwifi: fix notification wait bug

In "iwlwifi: consolidate the start_device flow"
Emmanuel added the return if the fw isn't there
but forgot to take into account that the struct
for notification wait needs to be added only
after the check -- fix that.

Subject: [PATCH 4274/6423] iwlwifi: abstract out notification wait support

This will be sharable, but needs to live in the
op_mode as it is dependent on command processing.
Make a library out of the notification wait code.

Since I wrote all of the code originally and only
Intel employees changed it, we can also relicense
it to dual BSD/GPL.

Subject: [PATCH 4275/6423] iwlwifi: move ucode_owner to priv

The transport doesn't really need to know as
we can enforce it in the command wrapper.
Move the ucode_owner variable into priv and
do all enforcing there.

All variables related to uCode loading (the
waitqueue and done indication) should be in
the PCI-E transport's private data as this
is transport specific. Move them there.

Subject: [PATCH 4277/6423] iwlwifi: move irq to PCIe

Even if the variable might also be used by other
transports, there's no need for anything outside
of the transport itself to access it, so move it
into the private area.

Subject: [PATCH 4278/6423] iwlwifi: move packet to transport

The base packet structure will (hopefully) be
the same for all transports, but what is in it
differs. Remove the union of all the possible
contents and move the packet itself into the
transport header file. This requires changing
all users of the union to just use pkt->data.

This function is only used in iwl-scan.c, so
if we move it up a little in the file it can
be made static.

So don't lock / unlock with _bh() while bottom halves are already
disabled.

Subject: [PATCH 4288/6423] ASoC: imx: imx-audmux: Fix section mismatch

Fix the following section mismatch warning:

WARNING: vmlinux.o(.data+0x35be8): Section mismatch in reference from the variable imx_audmux_driver to the function .init.text:imx_audmux_probe()
The variable imx_audmux_driver references
the function __init imx_audmux_probe()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console

Subject: [PATCH 4289/6423] lib: reduce the use of module.h wherever possible

For files only using THIS_MODULE and/or EXPORT_SYMBOL, map
them onto including export.h -- or if the file isn't even
using those, then just delete the include.  Fix up any implicit
include dependencies that were being masked by module.h along
the way.

Subject: [PATCH 4290/6423] tcp: md5: correct a RCU lockdep splat

commit a8afca0329 (tcp: md5: protects md5sig_info with RCU) added a
lockdep splat in tcp_md5_do_lookup() in case a timer fires a tcp
retransmit.

At this point, socket lock is owned by the sofirq handler, not the user,
so we should adjust a bit the lockdep condition, as we dont hold
rcu_read_lock().

it to bool because it is a internal switch for debugging.

Subject: [PATCH 4292/6423] staging: android/lowmemorykiller: Don't unregister
 notifier from atomic context

The lowmemorykiller registers an atomic notifier for notfication of when
the task is freed.  From this atomic notifier callback, it removes the
atomic notifier via task_free_unregister().  This is incorrect because
atomic_notifier_chain_unregister() calls syncronize_rcu(), which can
sleep, which shouldn't be done from an atomic notifier.

Fix this by registering the notifier during init, and only unregister it
if the lowmemorykiller is unloaded.

iio_read_channel_ext_info and iio_write_channel_ext_info causing the following

Subject: [PATCH 4297/6423] staging: zsmalloc: add ZS_MAX_PAGES_PER_ZSPAGE

This patch moves where max_zspage_order is declared and
changes its meaning.  "Order" typically implies 2^order
of something; however, it is currently being used as the
"maximum number of single pages in a zspage".  To add clarity,
ZS_MAX_ZSPAGE_ORDER is now used to calculate ZS_MAX_PAGES_PER_ZSPAGE,
which is 2^ZS_MAX_ZSPAGE_ORDER and is the upper bound on the number
of pages in a zspage.

The patch 2080913e017a: "staging: r8712u: Fix regression caused by
commit 8c213fa" from Feb 25, 2012, leads to the following Smatch
complaint:

drivers/staging/rtl8712/usb_intf.c:629 r871xu_dev_remove()
	 warn: variable dereferenced before check 'padapter' (see line 625)

The fix is to move the new statements inside the block where padapter
is not NULL.

Subject: [PATCH 4302/6423] staging:iio:tsl2563 rewrite probe error handling

tsl2563 probe function has two minor issues with it's error handling paths:
1) it is silent (did not report errors to dmesg)
2) did not return failure code (mixed up use of ret and err)

and two major issues:
3) goto fail2 would corrupt a free memory pool ("double free")
4) device registration failure did NOT cancel/flush delayed work.
   (and thus dereference a freed data structure later)

The "double free" is subtle and was introduced with this change:
    Author: Jonathan Cameron <jic23@cam.ac.uk>
    Date:   Mon Apr 18 12:58:55 2011 +0100
    staging:iio:tsl2563 take advantage of new iio_device_allocate private data.

Originally, chip was allocated seperately. Now it's appended to the
indio_dev by iio_allocate_device(sizeof(*chip)). So we only need one
kfree call as well (in iio_free_device()).

Gory details of tracking this down are here:
   http://crosbug.com/26819

Despite iio_device_registration failing, system can at least now boot.
Will follow up with a fix to "double register : in_intensity_both_raw"
error that is included in the bug report.

Now that 'struct drm_plane' has a pixel_format field, use that.  And
fix a minor typo.

Subject: [PATCH 4307/6423] staging: drm/omap: defer unpin until scanout
 completes

When flipping, defer unpinning until scanout completes, as indicated
by the appropriate END_WIN irq.

This also re-organizes things a bit, in replacing omap_fb_{pin,unpin}
with omap_fb_replace(), to make it easier to add support for scanout
synchronized DMM refill mode (flipping by just reprogramming DMM
synchronized with DSS scanout).

Subject: [PATCH 4309/6423] staging: drm/omap: Disable DMM debugfs for OMAP3

OMAP3 does not contain a DMM/Tiler block.  As such, we should not
be exposing any DMM debugfs entries on OMAP3 platforms.

Added inline helper function to verify existence of DMM.

Subject: [PATCH 4311/6423] staging: drm/omap: Get DMM resources from hwmod

This patch splits the DMM off into a separate sub-device, in order to
utilize the platform device information that was created as part of
the OMAP hwmod entry for the DMM.

The driver probe function queries the iomem resource and IRQ using
standard platform_get functions.

The OMAP DRM driver now calls the platform_driver_register() function
for the subordinate DMM driver inside its probe function.  This
guarantees the required order for the DMM and ensures the DMM resources
are available for use by the DRM driver.

Subject: [PATCH 4315/6423] RDMA/cxgb3: Don't pass irq flags to flush_qp()

Since flush_qp() is always called with irqs disabled, all the locking
inside flush_qp() and __flush_qp() doesn't need irq save/restore.

Further, passing the flag variable from iwch_modify_qp() is just wrong
and causes a WARN_ON() in local_bh_enable().

Subject: [PATCH 4316/6423] RDMA/iwcm: Reject connect requests if cmid is not
 in LISTEN state

When destroying a listening cmid, the iwcm first marks the state of
the cmid as DESTROYING, then releases the lock and calls into the
iWARP provider to destroy the endpoint.  Since the cmid is not locked,
its possible for the iWARP provider to pass a connection request event
to the iwcm, which will be silently dropped by the iwcm.  This causes
the iWARP provider to never free up the resources from this connection
because the assumption is the iwcm will accept or reject this connection.

The solution is to reject these connection requests.

Subject: [PATCH 4317/6423] spi/spi-sh: add IORESOURCE_MEM_TYPE_MASK decoding
 for access size

This SPI controller's access size is 32, or 8-bit. The previous driver
supported 32-bit only. So, this patch adds IORESOURCE_MEM_TYPE_MASK
decoding, an then, the driver can handle the SPI controller of 8-bit.

From ffbbdd21329f3e15eeca6df2d4bc11c04d9d91c0 Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Wed, 22 Feb 2012 10:05:38 +0100
Subject: [PATCH 4319/6423] spi: create a message queueing infrastructure

This rips the message queue in the PL022 driver out and pushes
it into (optional) common infrastructure. Drivers that want to
use the message pumping thread will need to define the new
per-messags transfer methods and leave the deprecated transfer()
method as NULL.

Most of the design is described in the documentation changes that
are included in this patch.

Since there is a queue that need to be stopped when the system
is suspending/resuming, two new calls are implemented for the
device drivers to call in their suspend()/resume() functions:
spi_master_suspend() and spi_master_resume().

ChangeLog v1->v2:
- Remove Kconfig entry and do not make the queue support optional
  at all, instead be more agressive and have it as part of the
  compulsory infrastructure.
- If the .transfer() method is implemented, delete print a small
  deprecation notice and do not start the transfer pump.
- Fix a bitrotted comment.
ChangeLog v2->v3:
- Fix up a problematic sequence courtesy of Chris Blair.
- Stop rather than destroy the queue on suspend() courtesy of
  Chris Blair.

 SPI MESSAGE QUEUE
 
-The bulk of the driver will be managing the I/O queue fed by transfer().
+If you are happy with the standard queueing mechanism provided by the
+SPI subsystem, just implement the queued methods specified above. Using
+the message queue has the upside of centralizing a lot of code and
+providing pure process-context execution of methods. The message queue
+can also be elevated to realtime priority on high-priority SPI traffic.
+
+Unless the queueing mechanism in the SPI subsystem is selected, the bulk
+of the driver will be managing the I/O queue fed by the now deprecated
+function transfer().
 
 That queue could be purely conceptual.  For example, a driver used only
 for low-frequency sensor access might be fine using synchronous PIO.

Don't store the bootinfo string and the ecc status string with
the recovered old log data.  This will simplify refactoring the
persistent ram code out of the ram console code later.

Subject: [PATCH 4322/6423] staging: android: ram_console: drop early buffer
 support

Early ramconsole is not very useful, an early crash will prevent
getting the logged data out on the next boot, and CONFIG_DEBUG_LL=y
will get the same information.  Drop it to simplify a future
refactoring.

Subject: [PATCH 4328/6423] Bluetooth: Set security level on incoming pairing
 request

If a master would like to raise the security level, it will send a
pairing request. While the pending security level is set on an incoming
security request (from a slave), it is not set on a pairing request. As
a result, the security level would not be raised on the slave in such
case.

Fix this by setting the pending security when receiving pairing
requests according to the requested authorization.

Subject: [PATCH 4329/6423] af_iucv: handle netdev events

In case of transport through HiperSockets the underlying network
interface may switch to DOWN state or the underlying network device
may recover. In both cases the socket must change to IUCV_DISCONN
state. If the interface goes down, af_iucv has a chance to notify
its connection peer in addition.

ctcmpc debugging can be activated defining constant DEBUGCCW.
The debugging part contains wrong checks for 64 bit addresses.
Thus the debugging version does not compile.
This patch corrects the 64-bit address checks to make it
compilable.

Subject: [PATCH 4333/6423] ctcm: use correct idal word list for ctcmpc

Communication Server Linux uses the ctcmpc code of the ctcm driver.
Sending problems have shown up caused by a wrong idal word list for
the first ccw. Function ctcmpc_chx_txdone() invokes the function
to prepare the idal word list without setting an appropriate length
for the first ccw, which may lead to an incomplete idal word list.
This patch sets the maximum buffer size as data length of the first
ccw. Thus correct idal word lists are guaranteed in all cases.

Setting an invalid mac-address for a qeth layer2 device returns
with a strange error code:
# ip link set hsi1 address 00:00:00:00:00:01
   RTNETLINK answers: Unknown error 18446744073709486085
Problem is caused by wrong usage of the return_code field within
structure qeth_ipa_cmd.
With this patch the ip command above returns

Subject: [PATCH 4335/6423] lcs: Return zero from ccwgroup devs set_offline
 function

A return code of non-zero of the devs ccwgroup set_offline function
leaves the dev in online state. Having done a partly offlining
may leave the dev in unusable state. To make sure the dev is set to
offline, zero is returned. A setup trace entry is written in case
the offlining steps encountered some trouble.

While for a user mode register dump it may be reasonable to skip
those (albeit x86-64 doesn't do so), for kernel mode dumps these
should be printed to make sure all information possibly
necessary for analysis is available.

Subject: [PATCH 4343/6423] [media] s5p-fimc: Convert to the device managed
 resources

The devm_* functions are used in the platform device probe() for data
that is freed on driver removal. The managed device layer takes care
of undoing actions taken in the probe callback() and freeing resources
on driver detach. This eliminates the need for manually releasing
resources and simplifies error handling.

Add support for cropping and composition setup on the video capture
node through VIDIOC_S/G_SELECTION ioctls. S/G_CROP, CROPCAP ioctls
are still  supported for applications since the core will translate
them to *_selection handler calls.

Subject: [PATCH 4346/6423] [media] s5p-csis: Convert to the device managed
 resources

The devm_* functions are used in the platform device probe() for data
that is freed on driver removal. The managed device layer takes care
of undoing actions taken in the probe callback() and freeing resources
on driver detach. This eliminates the need for manually releasing
resources and simplifies error handling.

Subject: [PATCH 4347/6423] [media] media: vb2: support userptr for PFN
 mappings

Some video devices need to use contiguous memory which is
not backed by pages as it happens with vmalloc. This patch
provides USERPTR handling for those devices.

Subject: [PATCH 4352/6423] [media] s5p-jpeg: Adapt to new controls

Adapt to new controls (subsampling).

For encoding, the destination format now needs to be set to V4L2_PIX_FMT_JPEG
and the subsampling (4:2:2 or 4:2:0) needs to be set using the respective
control (V4L2_CID_JPEG_CHROMA_SUBSAMPLING). Required buffer size for
destination image during encoding is no longer deduced from the format (which
generally implied overestimation), but needs to be given from userspace in
sizeimage.

Not strictly related to the added controls, this patch also fixes setting the
subsampling of the destination image for decoding, depending on the destination
format.

 pkt_scan

The JPEG header is always the same, so, it does not need to be rebuild
each time a new frame is received.

 exposure for po2030n
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The auto gain uses the knee algorithm.
Adding the setexposure control function forced to:
- rename of the previous function setexposure
- add a specific auto setting function

Subject: [PATCH 4363/6423] [media] gspca - zc3xx: Adjust the JPEG
 decompression tables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As the bridge register 08 defines the JPEG compression quality,
it must be changed on JPEG quality change and also, the decompression
tables must be adjusted when the register varies.

Subject: [PATCH 4370/6423] [media] it913x ver 1.26 change to remove
 interruptible mutex locks

Some virtual I2C commands are missed along some PID filtering
commands resulting complete stall of driver.

Since dvb-usb cannot handle the -EAGAIN error and commands
generally should not be missed mutex_lock is used instead.

Subject: [PATCH 4371/6423] [media] it913x ver 1.27 Allow PID 8192 to turn PID
 filter off

Allow PID 8192 to turn PID filter off in USB high speed.

The PID number is still written to the PID index and will only
turn on again if that index is set to 0.

Subject: [PATCH 4372/6423] [media] it913x-fe ver 1.15 read signal strenght
 using reg VAR_P_INBAND

Read signal strength using VAR_P_INBAND and apply FEC preferred values.

Note this does not work on IT9137 devices even with dvb-usb-it9135-01.fw
firmware.

Config read_sl allows switch between read signal strength and signal
level.

Subject: [PATCH 4373/6423] [media] cx22702: Fix signal strength

The signal strength value returned is not quite correct, it decreases
when I increase the gain of my antenna, and vice versa. It also
doesn't span over the whole 0x0000-0xffff range. Compute a value which
at least increases when signal strength increases, and spans the whole
allowed range.

In practice I get 67% with my antenna fully amplified and 51% with
no amplification. This is close enough to what I get on my other
DVB-T adapter with the same antenna.

 lock-unlock in [read|write]_reg_fp

If go7007_usb_vendor_request() fails in write_reg_fp()
or in read_reg_fp(), the usb->i2c_lock mutex left locked.

The patch moves mutex_unlock(&usb->i2c_lock) before check
for go7007_usb_vendor_request() returned value.

Subject: [PATCH 4375/6423] [media] em28xx: pre-allocate DVB isoc transfer
 buffers

On MIPS/ARM set-top-boxes, as well as old x86 PCs, memory allocation failures
in the em28xx driver are common, due to memory fragmentation over time, that
makes impossible to allocate large chunks of coherent memory.
A typical system with 256/512 MB of RAM fails after just 1 day of uptime (see
the old thread for detailed reports and crashlogs).

In fact, the em28xx driver allocates memory for USB isoc transfers at runtime,
as opposite to the dvb-usb drivers that allocates the USB buffers when the
device is initialized, and frees them when the device is disconnected.

Moreover, in digital mode the USB isoc transfer buffers are freed, allocated
and cleared every time the user selects a new channel, wasting time and
resources.

This patch solves both problems by allocating DVB isoc transfer buffers in
em28xx_usb_probe(), and freeing them in em28xx_usb_disconnect().
In fact, the buffers size and number depend only on the max USB packet size
that is parsed from the USB descriptors in em28xx_usb_probe(), so it can
never change for a given device.

This approach makes no sense in analog mode (as the buffer size depends on
the alternate mode selected at runtime), the patch creates two separate sets
of buffers for digital and analog modes.

For digital-only devices, USB buffers are created when the device is probed
and freed when the device is disconnected.
For analog-only devices, nothing changes: isoc buffers are created at runtime.
For hybrid devices, two sets of buffers are maintained: the digital-mode
buffers are created when the device is probed, and freed when the device is
disconnected; analog-mode buffers are created/destroyed at runtime as before.
So, in analog mode, digital and analog buffers coexists at the same time: this
can be justified by the fact that digital mode is by far more commonly used
nowadays, so it makes sense to optimize the driver for this use case scenario.

The patch has been tested in the last few days on a x86 PC and a MIPS
set-top-box, with the PCTV 290e (digital only) and the Terratec Hybrid XS
(hybrid device). With the latter, I switched several times between analog and
digital mode (Kaffeine/TvTime) with no issue at all.
I unplugged/plugged the devices several times with no problem.
Also, after over 3 days of normal usage in the MPIS set-top-box, the PCTV 290e
was still up and running.

Subject: [PATCH 4376/6423] [media] as102: map URB DMA addresses in the driver

On a set-top-box based on the Broadcom 7405 SoC (MIPS), the Abilis as102 driver
causes a kernel oops while trying to map the URB stream buffers DMA addresses:

CPU 0 Unable to handle kernel paging request at virtual address 007b9900,
epc == 80010cc4, ra == 8039d108

[<8000ecfc>] stack_done+0x20/0x40

On other boxes based on older SoCs (7401) this doesn't happen, so it looks like
a bug in the kernel specific to MIPS SMP. This issue has been reproduced on
several kernel versions from 2.6.18 to 3.1.0.

Since the base DMA address and the offsets are known, it is possible to map
the DMA addresses of the URB buffers directly in the driver. This workaround
fixes the problem and has been tested on both MIPS and x86 CPUs with success.

By the way, with this fix the driver works perfectly fine on the set-top-box:
both UHF and VHF frequencies are tuned without problems, and zapping is quite
fast. SNR and signal strength reports seems to work fine, too.

The only remaining problem (on both the PC and the set-top-box) is that after
a soft reboot the device is not recognized again by the kernel. It requires
a power cycle (or a manual unplug/replug) to be recognized again. So probably
the device state is not reset properly at shut-down.

Subject: [PATCH 4378/6423] [media] lgdt330x: fix signedness error in
 i2c_read_demod_bytes()

The error handling in lgdt3303_read_status() and lgdt330x_read_ucblocks()
doesn't work, because i2c_read_demod_bytes() returns a u8 and (err < 0)
is always false.

        err = i2c_read_demod_bytes(state, 0x58, buf, 1);
        if (err < 0)
                return err;

Change the return type of i2c_read_demod_bytes() to int.  Also change
the return value on error to -EIO to make (err < 0) work.

Subject: [PATCH 4379/6423] GFS2: Remove a __GFP_NOFAIL allocation

In order to ensure that we've got enough buffer heads for flushing
the journal, the orignal code used __GFP_NOFAIL when performing
this allocation. Here we dispense with that in favour of using a
mempool. This should improve efficiency in low memory conditions
since flushing the journal is a good way to get memory back, we
don't want to be spinning, waiting on memory allocations. The
buffers which are allocated via this mempool are fairly short lived,
so that we'll recycle them pretty quickly.

Although there are other memory allocations which occur during the
journal flush process, this is the one which can potentially require
the most memory, so the most important one to fix.

The amount of memory reserved is a fixed amount, and we should not need
to scale it when there are a greater number of filesystems in use.

Subject: [PATCH 4380/6423] wl12xx: implement SW Tx watchdog

Track freed FW blocks during Tx. If no blocks were freed during a
predefined timeout, initiate a HW recovery. This helps in situations
when the FW watchdog fails.

Don't trigger recovery during activities that can temporarily stop
Tx. This includes:
- scanning
- buffering packets for sleeping stations (AP role)
- ROC on any role

Subject: [PATCH 4381/6423] [media] V4L: mx2_camera: remove unsupported i.MX27
 DMA mode, make EMMA mandatory

The i.MX27 DMA support was introduced with the initial commit of this
driver and originally created by me. However, I never got this stable
due to the racy DMA engine and used the EMMA engine instead. As the DMA
support is most probably unused and broken in its current state, remove
it. EMMA becomes the only supported mode on i.MX27.

This also helps us get rid of another user of the legacy i.MX DMA
support and remove the dependency on ARCH_MX* macros as these are
scheduled for removal.

Subject: [PATCH 4383/6423] [media] media i.MX27 camera: add start_stream and
 stop_stream callbacks

Add "start_stream" and "stop_stream" callback in order to enable
and disable the eMMa-PrP properly and save CPU usage avoiding
IRQs when the device is not streaming. This also makes the driver
return 0 as the sequence number of the first frame.

Subject: [PATCH 4384/6423] [media] media i.MX27 camera: improve discard buffer
 handling

The way discard buffer was previously handled lead
to possible races that made a buffer that was not
yet ready to be overwritten by new video data. This
is easily detected at 25fps just adding "#define DEBUG"
to enable the "memset" check and seeing how the image
is corrupted.

A new "discard" queue and two discard buffers have
been added to make them flow trough the pipeline
of queues and thus provide suitable event ordering.

any other IRQs that can race with this ISR.

Subject: [PATCH 4388/6423] [media] media: i.MX27 camera: return IRQ_NONE if no
 IRQ status bit is set

If active_bufs() list is empty and no IRQ status bit is set
we are probably dealing with a share IRQ. Return IRQ_NONE in
this case.

Subject: [PATCH 4390/6423] [media] media: i.MX27 camera: more efficient
 discard buffer handling

Some elements of 'mx2_buffer' are grouped together in another
auxiliary structure. This way we don't need to have unused
'vb2_buffer' structures for both discard buffers.

csi clock frequency is already shown by:

		clk_get_rate(pcdev->clk_csi));

,so no need to have the dev_dbg call to present the same information.

Subject: [PATCH 4394/6423] [media] rc/ir-raw: use kfifo_rec_ptr_1 instead of
 kfifo

Raw IR events are passed to the raw event thread through a kfifo. The
size of the event struct is 12 bytes, and space for 512 events is
reserved in the kfifo (6144 bytes), however this is rounded down to 4096
bytes (the next power of 2) by __kfifo_alloc().

4096 bytes is not divisible by 12 therefore if the fifo fills up a third
of a record will be written in the end of the kfifo by
ir_raw_event_store() because the recsize of the fifo is 0 (it doesn't
have records). When this is read by ir_raw_event_thread() a corrupted or
partial record will be read, and in the case of a partial record the
BUG_ON(retval != sizeof(ev)) gets hit too.

According to samples/kfifo/record-example.c struct kfifo_rec_ptr_1 can
handle records of a length between 0 and 255 bytes, so change struct
ir_raw_event_ctrl to use that instead of struct kfifo.

"f" wasn't checked consistently, so static checkers complain.  This
function is always called with a valid "f" pointer, so I have removed
the check.

Also the indenting was messed up.

I don't have this hardware and I don't know the subsystem very well.  So
please review this patch carefully.  The original code definitely looks
buggy though.

Sparse complains about some endian bugs where little endian bugs are
treated as cpu endian.

Subject: [PATCH 4408/6423] [media] v4l2-ctrls: v4l2_ctrl_add_handler should
 add all refs

Currently v4l2_ctrl_add_handler adds only the controls that are owned
by the handler. This is wrong. Instead all controls, whether owned or
not, should be added.

This is also implied by the v4l2-controls.txt documentation and it is
clearly the right thing to do. The only reason this was never noticed
before is because we never did this. Only recent changes in ivtv made
this error visible because there a third handler layer was added (handler
A inherits from handler B which inherits from C, D and E). Without this
change handler A only sees the controls owned by handler B and the controls
from C, D and E are missing.

Subject: [PATCH 4409/6423] [media] ivtv: simplify how the decoder controls are
 set up

The code was unnecessarily complex, introducing a hdl_out handler that was
not needed. Instead just add the controls to the cxhdl.hdl handler directly.

Subject: [PATCH 4414/6423] [media] media: ir-sony-decoder: 15bit function
 decode fix

The raw Sony IR decoder decodes 15bit messages slightly incorrectly.
To decode the function number, it shifts the bits right by 7 so that the
function is in bits 7:1, masks with 0xFD (0b11111101), and does an 8 bit
reverse so it ends up in bits 6:0. The mask should be 0xFE to correspond
with bits 7:1 (0b11111110).

The old mask had the effect of dropping the MSB of the function number
from bit 6, and leaving the LSB of the device number in bit 7.

Subject: [PATCH 4424/6423] staging: android: ram_console: split out persistent
 ram

Split ram_console into two halves.

persistent_ram is a set of apis that handle a block of memory
that does not get erased across a reboot.  It provides functions
to fill it as a single buffer or a ring buffer, and to extract
the old data after a reboot.  It handles ecc on the data to
correct bit errors introduced during reboot.

ram_console is now a small wrapper around persistent_ram that
feeds console data into the ringbuffer, and exports the old
data to /proc/last_kmsg after a reboot.

From 9cc05ad97c5728aaf4db94490daf41f8958b5aee Mon Sep 17 00:00:00 2001
From: Colin Cross <ccross@android.com>
Date: Wed, 7 Mar 2012 17:34:33 -0800
Subject: [PATCH 4425/6423] staging: android: persistent_ram: refactor ecc
 support

Remove CONFIG_ANDROID_RAM_CONSOLE_ERROR_CORRECTION and related
 #ifdefs.  Also allow persistent ram zones without ecc enabled.
For some use cases, like the data portion of the upcoming
persistent_vars patches, or a persistent ftrace ringbuffer,
ecc on every update is too expensive.

From 404a6043385de17273624b076599669db5ad891f Mon Sep 17 00:00:00 2001
From: Colin Cross <ccross@android.com>
Date: Wed, 7 Mar 2012 17:34:34 -0800
Subject: [PATCH 4426/6423] staging: android: persistent_ram: handle reserving
 and mapping memory

Replace the ioremapped memory passed in from the drivers with
a memblock_reserve and vmap.  Adds a new function,
persistent_ram_early_init, designed to be called from the machine
init_early callback, that calls memblock_remove and saves the
provided persistent ram area layout.

Drivers only pass in their struct device * and ecc settings.
Locating and mapping the memory is now handled entirely within
persistent_ram.

Also, convert ram_console to the new persistent_ram_init
parameters that only take a struct device * and ecc settings.

[jstultz: Fix pr_info casting issues on 64bit, folded two
patches as the build breaks if they are apart. Also replaced
phys_to_page() w/ pfn_to_page(addr>>PAGE_SHIFT), as phys_to_page
is only on a few arches.]

Subject: [PATCH 4427/6423] staging: android: persistent_ram: make
 persistent_ram_write atomic

Allow persistent_ram_write to be called on multiple cpus at
the same time, as long as ecc is not in use.  Uses atomics
for the buffer->start and buffer->size counters.

Subject: [PATCH 4430/6423] staging: android: ram_console: honor dmesg_restrict

The Linux kernel has a setting called dmesg_restrict. When true,
only processes with CAP_SYSLOG can view the kernel dmesg logs. This
helps prevent leaking of kernel information into user space.

On Android, it's possible to bypass these restrictions by viewing
/proc/last_kmsg.

This change makes /proc/last_kmsg require the same permissions as
dmesg.

Date: Fri, 17 Feb 2012 07:55:06 +0000
Subject: [PATCH 4440/6423] viafb: modetable conversion

This patch converts the modetables used in viafb to
- remove the strange thing that sync_end and blanking_end contained
  the length and not the absolute value
- remove hundreds of useless defines
- use fb_videomode and not our own definition so modes defined in
  the subsystem and received via EDID are compatible with ours

As the modes are now stored in a flat structure and no longer in a
tree like thing the lookup time was increased but as it is a rare
event anyway it shouldn't matter. Otherwise the behaviour should be
the same as before.

Subject: [PATCH 4441/6423] viafb: avoid refresh and mode lookup in set_par

As check_var already ensures that the mode is valid there is no need
to do those expensive lookups here again. The only thing that might
change is that the deprecated interface could report slightly
different refresh rates due to rounding errors.

This driver is broken, as reported by Jiri, and to quote Ben:
	Just remove the driver, I don't think anybody cares.
so I'm doing just that here.

From 079c9534a96da9a85a2a2f9715851050fbfbf749 Mon Sep 17 00:00:00 2001
From: Alan Cox <alan@linux.intel.com>
Date: Tue, 28 Feb 2012 14:49:23 +0000
Subject: [PATCH 4443/6423] vt:tackle kbd_table

Keyboard struct lifetime is easy, but the locking is not and is completely
ignored by the existing code. Tackle this one head on

- Make the kbd_table private so we can run down all direct users
- Hoick the relevant ioctl handlers into the keyboard layer
- Lock them with the keyboard lock so they don't change mid keypress
- Add helpers for things like console stop/start so we isolate the poking
  around properly
- Tweak the braille console so it still builds

There are a couple of FIXME locking cases left for ioctls that are so hideous
they should be addressed in a later patch. After this patch the kbd_table is
private and all the keyboard jiggery pokery is in one place.

This update fixes speakup and also a memory leak in the original.

Subject: [PATCH 4444/6423] tty: serial: OMAP: Fix oops due to NULL pdata in DT
 boot

The following commit: be4b0281956c5cae4f63f31f11d07625a6988766
(tty: serial: OMAP: block idle while the UART is transferring data in PIO mode),
is introducing an oops if OMAP is booted using device tree blob because
the pdata will not be initialized.

Check if pdata is set before de-referencing it.

Subject: [PATCH 4447/6423] iwlwifi: move iwl_sta_id_or_broadcast to user

There's only one user, so the function
can be moved into the correct file. It
also loses an argument along the way.

Subject: [PATCH 4450/6423] iwlwifi: remove unused argument from iwlagn_suspend

There's not much point in passing priv and
hw pointers since they can be derived from
each other, and the function doesn't use
the hw pointer anyway. Remove it.

Subject: [PATCH 4451/6423] iwlwifi: redesign PASSIVE_NO_RX workaround

The PASSIVE_NO_RX workaround currently crosses
through the op_mode and transport layers, which
is a bit odd. This also isn't necessary, if the
transport simply reports when queues are full
(or no longer full) the op_mode can keep track
of this state, and report to mac80211 only what
*it* thinks is appropriate. What is appropriate
can then be based on whether queues should be
stopped to wait for RX or not.

This significantly simplifies the transport API,
it no longer needs to expose anything to stop a
queue, nor to wake "any" queue, this can all be
handled in the upper layer completely.

Also simplify the handling to not be dependent
on the context, that makes little sense as the
queues are shared and both contexts have to be
on the same channel anyway.

Subject: [PATCH 4453/6423] iwlwifi: remove BT handlers from lib_ops

There's no need to have operations for
these as they simply depend on whether
the device has built-in bluetooth, so
just duplicate the information already
there (whether bt_params is present or
not).

Subject: [PATCH 4455/6423] iwlwifi: make EEPROM enhanced TX power a bool

There's no need to carry around the function
pointer when a boolean indicating that the
EEPROM stores enhanced TX power information
is sufficient.

Subject: [PATCH 4456/6423] iwlwifi: remove unused max_nrg_cck from sensitivity
 and constify

The sensitivity parameters are never modified, so they
should be const. Also remove the unused max_nrg_cck
value to save some space.

Subject: [PATCH 4458/6423] iwlwifi: dump stack when fail to gain access to the
 device

Print dump stack when the device is not responding. This should give
some more clue about the reason of failure. Also change the message we
print, since "MAC in deep sleep" is kinda confusing.

On the way add unlikely(), as fail to gain NIC access is hmm ...
unlikely.

Before we write to the device registers always check if

On the way change return type of grab_nic_access() to bool, and add
likely()/unlikely() statement.

Subject: [PATCH 4460/6423] iwlwifi: cleanup/fix memory barriers

wmb(), rmb() are not needed when writel(), readl() are used as
accessors for MMIO. We use them indirectly via iowrite32(),
ioread32().

What is needed mmiowb(), for synchronizing writes coming from
different CPUs on PCIe bridge (see in patch comments). This
fortunately is not needed on x86, where mmiowb() is just
defined as compiler barrier. As iwlwifi devices are most likely
not used on anything other than x86, this is not so important
fix.

Added a testmode command which tells iwl_rx_dispatch
to send the RX both as a notification to nl80211 and
with the registered RX handlers.

This is used for monitoring RX from userspace while preserving
the regular flows in the driver.

Subject: [PATCH 4473/6423] iwlwifi: remove messages from queue wake/stop

The only reason we ever stop/wake queues at
the transport level is now that they become
full (or non-full), so the messages aren't
useful any more -- remove them.

Subject: [PATCH 4475/6423] iwlwifi: don't delete AP station directly

With the mac80211 deauth sequence changes, the
station is deleted before the device is set
unassociated. This can cause the device to get
confused as it expects the station to be there
while the associated bit is set.

To fix this, do not delete the AP station from
the device when mac80211 asks for deletion,
instead just mark it as unused and rely on the
unassociated RXON to drop it from the station
database in the device.

In recent commit "mwifiex: correct bitrates advertised..", we have
removed 22Mbps and 72Mbps bitrates from supported bitrate array.
It means number of bitrates has reduced from 14 to 12.

Initialize ".n_bitrates" to array size instead of hardcoding it.

Subject: [PATCH 4482/6423] vt: push down the tty lock so we can see what is
 left to tackle

At this point we have the tty_lock guarding a couple of oddities, plus the
translation and unimap still.

We also extend the console_lock in a couple of spots where coverage is wrong
and switch vcs_open to use the right lock !

[Fixed the locking issue Jiri reported]

Subject: [PATCH 4487/6423] USB: cdc-acm, use tty_standard_install

This is a piece I missed the last time.

Do not copy the functionality all over the tree. Instead, use the
helper the tty layer provides us with.

Subject: [PATCH 4489/6423] TTY: let alloc_tty_driver deduce the owner
 automatically

Like the rest of the kernel, make a stub from alloc_tty_driver which
calls __alloc_tty_driver with proper owner. This will save us one more
assignment on the driver side.

Also this fixes some drivers which didn't set the owner. This allowed

Subject: [PATCH 4490/6423] TTY: remove minor_num from tty_driver

It was added back in 2004 and never used for anything real. Remove the
only assignment in the tree as well.

Subject: [PATCH 4491/6423] TTY: remove re-assignments to tty_driver members

All num, magic and owner are set by alloc_tty_driver. No need to
re-set them on each allocation site.

pti driver sets something different to what it passes to
alloc_tty_driver. It is not a bug, since we don't use the lines
parameter in any way. Anyway this is fixed, and now we do the right
thing.

This is from tty_reopen:
    struct tty_driver *driver = tty->driver;
    ...
    tty->driver = driver;
and it doesn't make sense at all. The driver is intended to be set in
initialize_tty_struct from tty_init_dev (initial open). So this set in
tty_reopen is not needed.

Subject: [PATCH 4495/6423] TTY: tty_driver, document tty->ops->shutdown
 limitation

Note that tty->ops->shutdown is called from whatever context the user
drops the last tty reference from. E.g. if one takes a reference in
an ISR, tty close happens on other CPU and the final tty put is from
the ISR, tty->ops->shutdown will be called from that hard irq context.

We would have a problem in vt if we start using tty refcounting from
other contexts than user there. It is because vt's shutdown uses
mutexes. This is yet to be fixed.

Subject: [PATCH 4497/6423] ALPHA: srmcons, fix racy singleton structure

The test and the assignment were racy. Make it really a singleton.
This is achieved by one global variable initialized at the module
init.

Subject: [PATCH 4498/6423] TTY: srmcons, convert to use tty_port

This is needed because the tty buffer will become a tty_port member
later. That will help us to wipe out most of the races and checks for
the tty pointer in hot paths.

Subject: [PATCH 4500/6423] TTY: remove unneeded tty->index checks

Checking if tty->index is in bounds is not needed. The tty has the
index set in the initial open. This is done in get_tty_driver. And it
can be only in interval <0,driver->num).

So remove the tests which check exactly this interval. Some are
left untouched as they check against the current backing device count.
(Leaving apart that the check is racy in most of the cases.)

Subject: [PATCH 4501/6423] TTY: ipwireless, fix tty->index handling

* do not test if tty->index is in bounds. It is always.
* tty->index is not a minor! Fix that.

>From now on, let's assume that the parameter of the function is tty
index with base being zero. This makes also the code more readable.

Factually, there is no real change as tty_driver->minor_start is zero,
so the tests are equivalent. But it did not make sense. And if this
had changed eventually, it would have caused troubles.

Again, no need to do that from the pci probe function.

Hmm, I noticed this driver is marked as BROKEN. Won't touch it more,
it has to be converted to dynamic tty driver allocation first.

Perhaps it is time to move it to staging?

If the timer ticks while we are holding the spinlock, the system

We want to know the value of the atomic variable in intr_connect after
the increment. But atomic_inc doesn't, per definition, return the
value.  It is just a pure coincidence that ia64 defines atomic_inc as
atomic_inc_return.

So fix this mistake by using atomic_inc_return properly.

Subject: [PATCH 4510/6423] TTY: speakup, do not use serialP

The structures there are going away. And speakup has enough troubles
already.

So define a structure similar to what 8250 does: old_serial_port.
There define an array of speed, port base and so on needed for
configuration. Then use this structure instead of serial_state defined
in serialP.h.

Subject: [PATCH 4511/6423] TTY: serialP, remove unused material

First, remove unused macro and rs_multiport_struct structure. Nobody
uses them at all.

Further, the 2 drivers (they are below) which use the rest of
structures from serialP.h (async_struct and serial_state) do not use
all the members. Remove the members:
* which are unused or
* which are only initialized and never used for something real.

Everybody should avoid the structures with a looong distance.

Finally, remove the ALPHA kludge MCR quirks. They are 1:1 copy from
8250.h. No need to redefine them here.

The 2 promised users of the structures:

Subject: [PATCH 4512/6423] TTY: amiserial, remove tasklet for tty_wakeup

tty_wakeup is safe to be called from all contexts. No need to schedule
a tasklet for that. Let's call it directly like in other drivers.

This allows us to kill another member of async_struct structure. (If
we remove the dummy uses in simserial.)

Subject: [PATCH 4513/6423] TTY: amiserial, use only one copy of async flags

Huh, why would one want to store two copies of them? Get rid of the
one from async_struct. That structure is going away as a whole soon.

Subject: [PATCH 4514/6423] drivercore: Add driver probe deferral mechanism

Allow drivers to report at probe time that they cannot get all the resources
required by the device, and should be retried at a later time.

This should completely solve the problem of getting devices
initialized in the right order.  Right now this is mostly handled by
mucking about with initcall ordering which is a complete hack, and
doesn't even remotely handle the case where device drivers are in
modules.  This approach completely sidesteps the issues by allowing
driver registration to occur in any order, and any driver can request
to be retried after a few more other drivers get probed.

v4: - Integrate Manjunath's addition of a separate workqueue
    - Change -EAGAIN to -EPROBE_DEFER for drivers to trigger deferral
    - Update comment blocks to reflect how the code really works
v3: - Hold off workqueue scheduling until late_initcall so that the bulk
      of driver probes are complete before we start retrying deferred devices.
    - Tested with simple use cases.  Still needs more testing though.
      Using it to get rid of the gpio early_initcall madness, or to replace
      the ASoC internal probe deferral code would be ideal.
v2: - added locking so it should no longer be utterly broken in that regard
    - remove device from deferred list at device_del time.
    - Still completely untested with any real use case, but has been
      boot tested.

Subject: [PATCH 4515/6423] iscsi-target: Fix dynamic -> explict NodeACL
 pointer reference

This patch fixes a free after use in lio_target_make_nodeacl() where
iscsi_node_acl was referenced from the original se_nacl_new allocation,
instead of from core_tpg_add_initiator_node_acl() in the case of dynamic
-> explict NodeACL conversion.

Subject: [PATCH 4516/6423] driver core: move the deferred probe pointer into

Nothing outside of the driver core needs to get to the deferred probe
pointer, so move it inside the private area of 'struct device' so no one
tries to mess around with it.

Subject: [PATCH 4518/6423] hpsim, fix SAL handling in fw-emu

The switch-cases of SAL_FREQ_BASE generate non-relocatable code. The
same as for the ifs one level upper. This causes oopses early in boot
because the kernel jumps to the hell instead of the offset in sal
callback.

So use ifs here for SAL_FREQ_BASE decision too.

Isn't there any compiler directive or settings to solve that cleanly?

Subject: [PATCH 4520/6423] hpsim, initialize chip for assigned irqs

Currently, when assign_irq_vector is called and the irq connected in
the simulator, the irq is not ready. request_irq will return ENOSYS
immediately. It is because the irq chip is unset.

Hence set the chip properly to irq_type_hp_sim. And make sure this is
done from both users of simulated interrupts.

Also we have to set handler here, otherwise we end up in
handle_bad_int resulting in spam in logs and no irqs handled. We use
handle_simple_irq as these are SW interrupts that need no ACK or
anything.

Subject: [PATCH 4521/6423] simserial, bail out when request_irq fails

Without this, the code succeeds when the port is opened by root and we
get unwanted interrupts storm on the first key stroke.

Instead of that, tell the user we failed and that we won't continue. I
suppose, the code was copied from the serial layer where we may want
to change the irq number, so we must allow open even of the failing
port. This is not the case for this driver at all.

The same as for amiserial. Use only one instance of the flags.

Also remove them from async_struct now. Nobody else uses them.

Subject: [PATCH 4523/6423] TTY: simserial/amiserial, use one instance of other
 members

This means:
* close_delay
* closing_wait
* line
* port
* xmit_fifo_size

This actually fixes a bug in amiserial. It initializes one and uses
the other of the close delays. Yes, duplicating structure members is
evil.

Subject: [PATCH 4524/6423] TTY: simserial, remove support of shared interrupts

It never worked there. The ISR was never written for that kind of
stuff. So remove all that crap with a hash of linked lists and pass
the pointer directly to the ISR.

BTW this answers the question there:
  * I don't know exactly why they don't use the dev_id opaque data
  * pointer instead of this extra lookup table

-> Because they thought they will support more devices bound to a
single interrupt w/o IRQF_SHARED. They would need exactly the hash
there.

What I don't understand is rebinding of the interrupt in the shutdown
path. They perhaps meant to do just synchronize_irq? In any case, this
is all gone and free_irq there properly.

By removing the hash we save some bits (exactly NR_IRQS * 8 bytes of
.bss and over a kilo of .text):
before:
   text    data     bss     dec     hex filename
  19600     320    8227   28147    6df3 ../a/ia64/arch/ia64/hp/sim/simserial.o
after:
   text    data     bss     dec     hex filename
  18568     320      28   18916    49e4 ../a/ia64/arch/ia64/hp/sim/simserial.o

Note that a shared interrupt could not work too. request_irq requires
data parameter to be non-NULL. So the whole IRQ_T exercise was
pointless.

Finally, this helps us remove another two members of async_struct :).

Subject: [PATCH 4525/6423] TTY: simserial, remove IRQ_T

We do not set ASYNC_SHARE_IRQ anywhere. And since IRQF_DISABLED is a
noop, pass zero to request_irq directly instead of this ugly macro.

Subject: [PATCH 4526/6423] TTY: amiserial, remove IRQ_ports

They used to work as a storage for 'info' pointer used in ISRs.  They
are not really needed. Just pass the pointer through request_irq to
the handlers.

It was set to NULL and tested in the ISRs, but we do not need the
tests as we disable all the interrupts at the same places where NULL
sets were.

Subject: [PATCH 4527/6423] TTY: serialP, merge serial_state and async_struct

This is the final step to get rid of the one of the structures.  A
further cleanup will follow. And I struct serial_state deserves cease
to exist after a switch to tty_port too.

While changing the lines, it removes also pointless tty->driver_data
casts.

Subject: [PATCH 4528/6423] TTY: amiserial, simplify set_serial_info

Do not copy whole serial_state. We only need to know whether the speed
is to be changed. Hence store the info in advance and use it later.
A simple bool is enough.

Also remove reduntant assignments and move the tests directly to the
'if'.

Subject: [PATCH 4529/6423] TTY: amiserial, pass tty down to functions

This avoids pain with tty refcounting and touching tty_port in the
future. It allows us to remove some info->tty tests because the tty
passed down to them can never be NULL.

Subject: [PATCH 4530/6423] TTY: simserial, pass tty down to functions

This avoids pain with tty refcounting and touching tty_port in the
future. It allows us to remove some state->tty tests because the tty
passed down to them can never be NULL.

Subject: [PATCH 4532/6423] TTY: amiserial/simserial, use close delays from
 tty_port

Note that previously simserial set the delay to 0. So we preserve
that. BUT, is it correct?

From d927d505c59a0c7353343174e6225c43c61fba6d Mon Sep 17 00:00:00 2001
From: Or Gerlitz <ogerlitz@mellanox.com>
Date: Wed, 11 Jan 2012 19:03:51 +0200
Subject: [PATCH 4535/6423] IB: Change CQE "csum_ok" field to a bit flag

Use a bit in wc_flags rather then a whole integer to hold the
"checksum OK" flag.  By itself, this change doesn't reduce the size of
struct ib_wc on 64bit machines -- it stays on 56 bytes because of
padding.  However, it will allow to add more fields in the future
without enlarging the struct.  Also, it will let us have a unified
approach with future libibverbs checksum offload reporting, because a
bit flag doesn't break the library ABI.

This patch was suggested during conversation with Liran Liss
<liranl@mellanox.com>.

Subject: [PATCH 4536/6423] dlm: fix slow rsb search in dir recovery

The function used to find an rsb during directory
recovery was searching the single linear list of
rsb's.  This wasted a lot of time compared to
using the standard hash table to find the rsb.

Subject: [PATCH 4537/6423] TTY: simserial, remove static initialization

We do not use any of the preinitialized rs_state members for something
real. So there is no need to initialize them. At the places we used
them for printing, just print the values.

And since only one port is supported, get rid of the loop. This
simplifies simrs_init a heap. Thus we can handle fail paths in a
standard way without panicing.

Subject: [PATCH 4540/6423] TTY: simserial no longer needs serialP

Let's do a spin-off of serial_state structure with only needed
elements.

And remove serialP crap from includes.

Subject: [PATCH 4541/6423] TTY: simserial, define local tty_port pointer

And use it to make the code more readable.

Since tport doesn't conflict with port anymore and there are not many
tport accessors left, do also s/\<tport\>/port/g.

I.e. remove more copied bloat.

The only change is that we wait_until_sent now. Which is what we

Subject: [PATCH 4546/6423] TTY: simserial, use tty_port_open

So now we convert startup to be ->activate of tty_port. This means we
no longer care about INITIALIZED and TTY_IO_ERROR flags.

After we have ->activate much of the code may go as it duplicates what
tty_port_open does. In this case tty_port_open adds block_til_ready to
the path. But we do not define carrier hooks, so it is a noop.

Subject: [PATCH 4547/6423] TTY: simserial, use tty_port_hangup

Convert shutdown to be tty_port_operations->shutdown. Then we can use
tty_port_hangup. (And we have to use tty_port_close.)

This means we no longer touch ASYNC_INITIALIZED, TTY_IO_ERROR. Also we
do not need to do any peculiar TTY logic in the file now.

From 6e9ebcfa20b15f0ccdd4b5395a3c63f79c21fa57 Mon Sep 17 00:00:00 2001
From: Jiri Slaby <jslaby@suse.cz>
Date: Mon, 5 Mar 2012 14:52:42 +0100
Subject: [PATCH 4551/6423] TTY: simserial, final cleanup

* remove pointless checks (tty cannot be NULL at that points)
* fix some printks (use __func__, print text directly w/o using global
  strings)
* remove some empty lines

This is the last patch for simserial. Overall, the driver is 400 lines
shorter. Being now at 560 lines.

It was tested using ski with a busybox userspace.

Subject: [PATCH 4554/6423] TTY: amiserial no longer needs serialP

amiserial is the last user of serialP.h. Let's move struct
serial_state directly to amiserial and remove serialP crap from
includes. Finally, remove the header from the tree completely.

Subject: [PATCH 4555/6423] TTY: amiserial, provide carrier helpers

This is a preparation for a switch to tty_port_block_til_ready. We
need amiga_carrier_raised and amiga_dtr_rts. The implementation is
taken from startup, shutdown and current block_til_ready.

Subject: [PATCH 4557/6423] TTY: amiserial, use tty_port_close_end

Hmm, the code was sleeping with interrupts disabled. This was not
good. Fix this by turning interrupts at an appropriate place. (The
race is protected by CLOSING flag.)

After the move, the code is identical to tty_port_close_end, so use
it!

Again, no need to duplicate the code. Let's use the helper.

Amiserial changes are only free of compilation errors. I have no

Subject: [PATCH 4562/6423] TTY: pdc_cons, use tty_port

Instead of digging a tty out of the tty_driver struct, which is not
defined to work, use tty_port properly. This includes proper tty
refcounting even though there is no possible race currently. But we
will need tty_port for tty buffers in the future anyway.

Subject: [PATCH 4563/6423] TTY: isdn/gigaset, do not set tty->driver_data to
 NULL

Close the window in open where driver_data is reset to NULL on each
open. It could cause other processes to get invalid retval from the
tty->ops operations because of the checks all over the code.

With this change we may do other cleanups. Now, the only valid check
for tty->driver_data != NULL is in close. This can happen only if open
fails at gigaset_get_cs_by_tty or try_module_get. The rest of checks
in various tty->ops->* are invalid as driver_data cannot be NULL
there. The same holds for cs->open_count. So remove them.

Subject: [PATCH 4564/6423] TTY: isdn/gigaset, use tty_port

Let us port the code to use tty_port. We now use open_count and tty
from there. This allows us also to use tty_port_tty_set with tty
refcounting instead of hand-written locking and logic.

Note that tty and open_count are no longer protected by cs->lock. It is
protected by tty_port->lock. But since all the places where they were
used are now switched to the helpers, we are fine.

This is supposed to be doing a shift before the comparison instead of
just doing a bitwise AND directly.  The current code means the start()
just returns without doing anything.

Subject: [PATCH 4566/6423] uevent: send events in correct order according to
 seqnum (v3)

The queue handling in the udev daemon assumes that the events are
ordered.

Before this patch uevent_seqnum is incremented under sequence_lock,
than an event is send uner uevent_sock_mutex. I want to say that code
contained a window between incrementing seqnum and sending an event.

This patch locks uevent_sock_mutex before incrementing uevent_seqnum.

v2: delete sequence_lock, uevent_seqnum is protected by uevent_sock_mutex
v3: unlock the mutex before the goto exit

Thanks for Kay for the comments.

Subject: [PATCH 4568/6423] USB: ehci-s5p: add DMA burst support

DMA burst support is added to improve performance in EHCI data
transfer. The USB EHCI controller on Exynos SoCs can use INCR16,
INCR8, and INCR4 mode. These modes of INSNREG00 register should
be set in order to enable DMA burst transfer. This feature is
also related to AHB spec.

Subject: [PATCH 4569/6423] USB: Microchip VID mislabeled as Hornby VID in
 ftdi_sio.

Microchip VID (0x04d8) was mislabeled as Hornby VID according to USB-IDs.

A Full Speed USB Demo Board PID (0x000a) was mislabeled as
Hornby Elite (an Digital Command Controller Console for model railways).

Most likely the Hornby based their design on
PIC18F87J50 Full Speed USB Demo Board.

Content-Transfer-Encoding: 8bit

Register all interfaces handled by this driver in a list, getting
rid of the dependency on usb_set_intfdata.  This allows further
generalization and simplification of the probe/create functions.

This is needed to decouple wdm_open from the driver owning the
interface, and it also allows us to share all the code in
wdm_create with drivers unable to do usb_set_intfdata.

Subject: [PATCH 4572/6423] usb: cdc-wdm: adding usb_cdc_wdm_register subdriver
 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This driver can be used as a subdriver of another USB driver, allowing
it to export a Device Managment interface consisting of a single interrupt
endpoint with no dedicated USB interface.

Some devices provide a Device Management function combined with a wwan
function in a single USB interface having three endpoints (bulk in/out
+ interrupt).  If the interrupt endpoint is used exclusively for DM
notifications, then this driver can support that as a subdriver
provided that the wwan driver calls the appropriate entry points on
probe, suspend, resume, pre_reset, post_reset and disconnect.

The main driver must have full control over all interface related
settings, including the needs_remote_wakeup flag. A manage_power
function must be provided by the main driver.

A manage_power stub doing direct flag manipulation is used in normal
driver mode.

HID devices should specify this in their interface descriptors, not in the
device descriptor. This fixes a "missing hardware id" bug under Windows 7 with
a VIA VL800 (3.0) controller.

Subject: [PATCH 4574/6423] mpc5200b/uart: select more tolerant uart prescaler
 on low baudrates

In addition to the /32 prescaler, the MPC5200B supports a second
baudrate prescaler /4 to reach higher baudrates.

The current calculation (introduced with commit 0d1f22e4) in the kernel
preferes this low prescaler as often as possible, but with some
imprecise counterparts the communication on low baudrates fails.

According a support-mail from freescale the low prescaler (/4) allows
just 1% tolerance in bittiming in contrast to 4% of the high prescaler
(/32).  The prescaler not only affects the baudrate-calculation, but
also the sampling of the bits on the wire.

With this patch, we use the slightly less precise, but higher tolerant
prescaler calculation on low baudrates up to (and including) 115200 baud
and the more precise calculation above.

Tested on a custom MPC5200B board with "fsl,mpc5200b-psc-uart".

Calculation Examples with prescaler (PS) 4 and 32 and divisor (DIV) on
various baudrates. Real stands for the real baudrate generated and Diff

+  1/30/2007		Philip Nicastro		Initial release. (v1.0.0.0)
+  2/27/2007		Philip Nicastro		Changed the metrousb_read_int_callback function to use a loop with the tty_insert_flip_char function to copy each byte to the tty layer. Removed the tty_buffer_request_room and the tty_insert_flip_string function calls. These calls were not supported on Fedora.
+  2/27/2007		Philip Nicastro		Released. (v1.1.0.0)
+  10/07/2011		Aleksey Babahin		Update for new kernel (tested on 2.6.38)
+						Add unidirection mode support

Subject: [PATCH 4576/6423] USB: serial: metro-usb: fix up usb_serial_register
 calls

The usb serial core has changed how the driver is to be registered and
unregistered recently.  Make these changes to the driver so that it will
properly build and work.

Subject: [PATCH 4578/6423] USB: serial: metro-usb: remove vendor and product
 module parameters

All new usb serial drivers should be using the dynamic id function, not
having module parameters for this type of thing.  So remove them before
anyone gets used to them being there.

This fixes up all of the coding style errors, and removes the initial,
unneeded comments on how to load the module and the old changelog which
are no longer needed.

There are still a number of coding style warnings left, I'll get to them
later.

Subject: [PATCH 4584/6423] USB: serial: metro-usb: remove function prototypes

By rearranging the functions a bit, we can remove all function
prototypes.

Note, this also deleted the _close function, as it wasn't needed, it was
doing the same thing the cleanup function did, so just call that
instead.

 comments

They aren't needed, make the checkpatch tool unhappy, and in some
places, aren't even correct.  So just remove them, they get in the way
and are messy.

We should use kzalloc() instead of kmalloc() and memset(), and remove an
unneeded void * cast as well.

Subject: [PATCH 4587/6423] USB: serial: metro-usb: move to use dev_dbg()
 instead of dbg()

This properly ties the driver into the dynamic debug system and provides
the needed device identification when the messages are printed out.

It also removes a ton of checkpatch warnings as well, which is always a
nice validation that it's the correct thing to do.

- *
- * This module implements the virtual ethernet device for iSeries LPAR
- * Linux.  It uses hypervisor message passing to implement an
- * ethernet-like network device communicating between partitions on
- * the iSeries.
- *
- * The iSeries LPAR hypervisor currently allows for up to 16 different
- * virtual ethernets.  These are all dynamically configurable on
- * OS/400 partitions, but dynamic configuration is not supported under
- * Linux yet.  An ethXX network device will be created for each
- * virtual ethernet this partition is connected to.
- *
- * - This driver is responsible for routing packets to and from other
- *   partitions.  The MAC addresses used by the virtual ethernets
- *   contains meaning and must not be modified.
- *
- * - Having 2 virtual ethernets to the same remote partition DOES NOT
- *   double the available bandwidth.  The 2 devices will share the
- *   available hypervisor bandwidth.
- *
- * - If you send a packet to your own mac address, it will just be
- *   dropped, you won't get it on the receive side.
- *
- * - Multicast is implemented by sending the frame frame to every
- *   other partition.  It is the responsibility of the receiving
- *   partition to filter the addresses desired.
- *
- * Tunable parameters:
- *
- * VETH_NUMBUFFERS: This compile time option defaults to 120.  It
- * controls how much memory Linux will allocate per remote partition
- * it is communicating with.  It can be thought of as the maximum
- * number of packets outstanding to a remote partition at a time.

Subject: [PATCH 4590/6423] powerpc: remove the legacy iSeries part of ibmvscsi

The PowerPC legacy iSeries platform is being removed and this code is
no longer selectable.  There is more clean up that can be done, but this
just gets the old code out of the way.

From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: Tue, 28 Feb 2012 13:44:58 +1100
Subject: [PATCH 4595/6423] powerpc: Remove legacy iSeries bits from assembly
 files

This removes the various bits of assembly in the kernel entry,
exception handling and SLB management code that were specific
to running under the legacy iSeries hypervisor which is no
longer supported.

Subject: [PATCH 4596/6423] powerpc: Use the same interrupt prolog for perfmon
 as other interrupts

The perfmon interrupt is the sole user of a special variant of the
interrupt prolog which differs from the one used by external and timer
interrupts in that it saves the non-volatile GPRs and doesn't turn the
runlatch on.

The former is unnecessary and the later is arguably incorrect, so
let's clean that up by using the same prolog. While at it we rename
that prolog to use the _ASYNC prefix.

Subject: [PATCH 4597/6423] powerpc: Rework runlatch code

This moves the inlines into system.h and changes the runlatch
code to use the thread local flags (non-atomic) rather than
the TIF flags (atomic) to keep track of the latch state.

The code to turn it back on in an asynchronous interrupt is
now simplified and partially inlined.

Subject: [PATCH 4598/6423] powerpc: Improve 64-bit syscall entry/exit

We unconditionally hard enable interrupts. This is unnecessary as
syscalls are expected to always be called with interrupts enabled.

While at it, we add a WARN_ON if that is not the case and
CONFIG_TRACE_IRQFLAGS is enabled (we don't want to add overhead
to the fast path when this is not set though).

Thus let's remove the enabling (and associated irq tracing) from
the syscall entry path. Also on Book3S, replace a few mfmsr
instructions with loads of PACAMSR from the PACA, which should be
faster & schedule better.

Subject: [PATCH 4599/6423] powerpc: Improve behaviour of irq tracing on 64-bit
 exception entry

Some exceptions would unconditionally disable interrupts on entry,
which is fine, but calling lockdep every time not only adds more
overhead than strictly needed, but also means we get quite a few
"redudant" disable logged, which makes it hard to spot the really
bad ones.

So instead, split the macro used by the exception code into a
normal one and a separate one used when CONFIG_TRACE_IRQFLAGS is
enabled, and make the later skip th tracing if interrupts were
already disabled.

Subject: [PATCH 4600/6423] powerpc: Call do_page_fault() with interrupts off

We currently turn interrupts back to their previous state before
calling do_page_fault(). This can be annoying when debugging as
a bad fault will potentially have lost some processor state before
getting into the debugger.

We also end up calling some generic code with interrupts enabled
such as notify_page_fault() with interrupts enabled, which could
be unexpected.

This changes our code to behave more like other architectures,
and make the assembly entry code call into do_page_faults() with
interrupts disabled. They are conditionally re-enabled from
within do_page_fault() in the same spot x86 does it.

While there, add the might_sleep() test in the case of a successful
trylock of the mmap semaphore, again like x86.

Also fix a bug in the existing assembly where r12 (_MSR) could get
clobbered by C calls (the DTL accounting in the exception common
macro and DISABLE_INTS) in some cases.

Subject: [PATCH 4601/6423] powerpc: Disable interrupts in 64-bit kernel FP and
 vector faults

If we get a floating point, altivec or vsx unavaible interrupt in
kernel, we trigger a kernel error. There is no point preserving
the interrupt state, in fact, that can even make debugging harder
as the processor state might change (we may even preempt) between
taking the exception and landing in a debugger.

So just make those 3 disable interrupts unconditionally.

Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

v2: On BookE only disable when hitting the kernel unavailable
    path, otherwise it will fail to restore softe as
    fast_exception_return doesn't do it.

Subject: [PATCH 4602/6423] powerpc: Add support for page fault retry and fatal
 signals

Other architectures such as x86 and ARM have been growing
new support for features like retrying page faults after
dropping the mm semaphore to break contention, or being
able to return from a stuck page fault when a SIGKILL is
pending.

This refactors our implementation of do_page_fault() to
move the error handling out of line in a way similar to
x86 and adds support for those two features.

Subject: [PATCH 4604/6423] powerpc: Fix register clobbering when accumulating
 stolen time

When running under a hypervisor that supports stolen time accounting,
we may call C code from the macro EXCEPTION_PROLOG_COMMON in the
exception entry path, which clobbers CR0.

However, the FPU and vector traps rely on CR0 indicating whether we
are coming from userspace or kernel to decide what to do.

So we need to restore that value after the C call

Subject: [PATCH 4605/6423] powerpc: Fix 64-bit BookE FP unavailable exceptions

We were using CR0.EQ after EXCEPTION_COMMON, hoping it still
contained whether we came from userspace or kernel space.

However, under some circumstances, EXCEPTION_COMMON will
call C code and clobber non-volatile registers, so we really
need to re-load the previous MSR from the stackframe and
re-test.

While there, invert the condition to make the fast path more
obvious and remove the BUG_OPCODE which was a debugging
leftover and call .ret_from_except as we should.

From cb3bc9d0de1e247268622acd40e0d2f8120f299c Mon Sep 17 00:00:00 2001
From: Gavin Shan <shangw@linux.vnet.ibm.com>
Date: Mon, 27 Feb 2012 20:03:51 +0000
Subject: [PATCH 4607/6423] powerpc/eeh: Cleanup comments in the EEH core

The EEH has been implemented on pSeries platform. The original
code looks a little bit nasty. The patch does cleanup on the
current EEH implementation so that it looks more clean.

        * Duplicated comments have been removed from the corresponding
          header files.
        * Comments have been reorganized so that it looks more clean.
        * The leading comments of functions are adjusted for a little
          bit so that the result of "make pdfdocs" would be more
          unified.
        * Function definitions and calls have unified format as "xxx()".
          That means the format "xxx ()" has been replaced by "xxx()".
        * There're multiple functions implemented for resetting PE. The
          position of those functions have been move around so that they
          are adjacent to each other to reflect their relationship.

From cce4b2d243ddd9e8d5da159b893117afd7ccad5c Mon Sep 17 00:00:00 2001
From: Gavin Shan <shangw@linux.vnet.ibm.com>
Date: Mon, 27 Feb 2012 20:03:52 +0000
Subject: [PATCH 4608/6423] powerpc/eeh: Cleanup function names in the EEH core

The EEH has been implemented on pSeries platform. The original
code looks a little bit nasty. The patch does cleanup on the
current EEH implementation so that it looks more clean.

        * Try adding prefix "eeh" for functions.
        * Some function names have been adjusted so that they looks
          shorter and meaningful.

From aa1e6374ae11788752535ae0c8c6395c9cad1393 Mon Sep 17 00:00:00 2001
From: Gavin Shan <shangw@linux.vnet.ibm.com>
Date: Mon, 27 Feb 2012 20:03:53 +0000
Subject: [PATCH 4609/6423] powerpc/eeh: Platform dependent EEH operations

EEH has been implemented on RTAS-compliant pSeries platform.
That's to say, the EEH operations will be implemented through RTAS
calls eventually. The situation limited feasible extension on EEH.
In order to support EEH on multiple platforms like pseries and powernv
simutaneously. We have to split the platform dependent EEH options
up out of current implementation.

The patch addresses supporting EEH on multiple platforms. The pseries
platform dependent EEH operations will be abstracted by struct eeh_ops.
EEH core components will be built based on the registered EEH operations.
With the mechanism, what the individual platform needs to do is implement
platform dependent EEH operations.

For now, the pseries platform is covered under the mechanism. That means
we have to think about other platforms to support EEH, like powernv.
Besides, we only have framework for the mechanism and we have to implement
it for pseries platform later.

Subject: [PATCH 4610/6423] powerpc/eeh: pseries platform EEH initialization

The platform specific EEH operations have been abstracted by
struct eeh_ops. The individual platroms, including pSeries, needs
doing necessary initialization before the platform dependent EEH
operations work properly.

The patch is addressing that and do necessary platform initialization
for pSeries platform. More specificly, it will figure out the tokens
of EEH related RTAS calls.

Subject: [PATCH 4611/6423] powerpc/eeh: pseries platform EEH operations

There're 4 EEH operations that are covered by the dedicated RTAS
call <ibm,set-eeh-option>: enable or disable EEH, enable MMIO and
enable DMA. At early stage of system boot, the EEH would be tried
to enable on PCI device related device node. MMIO and DMA for
particular PE should be enabled when doing recovery on EEH errors
so that the PE could function properly again.

The patch implements it and abstract that through struct
eeh_ops::set_eeh. It would be help for EEH to support multiple
platforms in future.

Subject: [PATCH 4612/6423] powerpc/eeh: pseries platform EEH PE address
 retrieval

There're 2 types of addresses used for EEH operations. The first
one would be BDF (Bus/Device/Function) address which is retrieved
from the reg property of the corresponding FDT node. Another one
is PE address that should be enquired from firmware through RTAS
call on pSeries platform. When issuing EEH operation, the PE address
has precedence over BDF address.

The patch implements retrieving PE address according to the given
BDF address on pSeries platform. Also, the struct eeh_early_enable_info
has been removed since the information can be figured out from
dn->pdn->phb->buid directly and that simplifies the code.

Subject: [PATCH 4613/6423] powerpc/eeh: pseries platform PE state retrieval

On pSeries platform, there're 2 dedicated RTAS calls introduced to
retrieve the corresponding PE's state: ibm,read-slot-reset-state and
ibm,read-slot-reset-state2.

The patch implements the retrieval of PE's state according to the
given PE address. Besides, the implementation has been abstracted by
struct eeh_ops::get_state so that EEH core components could support
multiple platforms in future.

Subject: [PATCH 4614/6423] powerpc/eeh: pseries platform EEH wait PE state

On pSeries platform, the PE state might be temporarily unavailable.
In that case, the firmware will return the corresponding wait time.
That means the kernel has to wait for appropriate time in order to
get the PE state.

The patch does the implementation for that. Besides, the function
has been abstracted through struct eeh_ops::wait_state so that EEH core
components could support multiple platforms in future.

Subject: [PATCH 4615/6423] powerpc/eeh: pseries platform EEH reset PE

On RTAS compliant pSeries platform, there is a dedicated RTAS call
(ibm,set-slot-reset) to reset the specified PE. Furthermore, two
types of resets are supported: hot and fundamental. the type of
reset is to be used actually depends on the included PCI device's
requirements.

The patch implements resetting PE on pSeries platform through RTAS
call. Besides, it has been abstracted through struct eeh_ops::reset
so that EEH core components could support multiple platforms in future.

Subject: [PATCH 4617/6423] powerpc/eeh: pseries platform EEH configure bridge

In order to enable particular PCI device, which has been included
in the parent PE. The involved PCI bridges should be enabled explicitly
if there has. On pSeries platform, there're dedicated RTAS calls
to fulfil the purpose.

The patch implements the function of configuring PCI bridges through
the dedicated RTAS calls. Besides, the function has been abstracted
by struct eeh_ops::configure_bridge so that the EEH core components
could support multiple platforms in future.

Subject: [PATCH 4618/6423] powerpc/pseries: Cleanup comments in EEH aux
 components

There're several EEH aux components and the patch does some cleanup
for them so that they look more clean.

        * Duplicated comments have been removed from the header file.
        * Comments have been reorganized so that it looks more clean.
        * The leading comments of functions are adjusted for a little
          bit so that the result of "make pdfdocs" would be more
          unified.
        * Function calls "xxx ()" has been replaced by "xxx()".

Subject: [PATCH 4619/6423] powerpc/eeh: Cleanup function names in EEH aux
 components

The patch does some cleanup on the function names of EEH
aux components. Currently, only couple of function names from
eeh_cache have been adjusted so that:

        * The function name has prefix "eeh_addr_cache".
        * Move around pci_addr_cache_build() in the header file
          to reflect function call sequence.

Subject: [PATCH 4620/6423] powerpc/eeh: Introduce EEH device

Original EEH implementation depends on struct pci_dn heavily. However,
EEH shouldn't depend on that actually because EEH needn't share much
information with other PCI components. That's to say, EEH should have
worked independently.

The patch introduces struct eeh_dev so that EEH core components needn't
be working based on struct pci_dn in future. Also, struct pci_dn, struct
eeh_dev instances are created in dynamic fasion and the binding with EEH
device, OF node, PCI device is implemented as well.

The EEH devices are created after PHBs are detected and initialized, but
PCI emunation hasn't started yet. Apart from that, PHB might be created
dynamically through DLPAR component and the EEH devices should be creatd
as well. Another case might be OF node is created dynamically by DR
(Dynamic Reconfiguration), which has been defined by PAPR. For those OF
nodes created by DR, EEH devices should be also created accordingly. The
binding between EEH device and OF node is done while the EEH device is
initially created.

The binding between EEH device and PCI device should be done after PCI
emunation is done. Besides, PCI hotplug also needs the binding so that
the EEH devices could be traced from the newly coming PCI buses or PCI
devices.

Subject: [PATCH 4621/6423] powerpc/eeh: Replace pci_dn with eeh_dev for EEH
 sysfs

With original EEH implementation, all EEH related statistics have
been put into struct pci_dn. We've introduced struct eeh_dev to
replace struct pci_dn in EEH core components, including EEH sysfs
component.

The patch shows EEH statistics from struct eeh_dev instead of struct
pci_dn in EEH sysfs component. Besides, it also fixed the EEH device
retrieval from PCI device, which was introduced by the previous patch
in the series of patch.

Subject: [PATCH 4622/6423] powerpc/eeh: Replace pci_dn with eeh_dev for EEH
 address cache

With original EEH implementation, struct pci_dn is used while building
PCI I/O address cache, which helps on searching the corresponding
PCI device according to the given physical I/O address. Besides, pci_dn
is associated with the corresponding PCI device while building its
I/O cache.

The patch replaces struct pci_dn with struct eeh_dev so that EEH address
cache won't depend on struct pci_dn. That will help EEH to become an
independent module in future. Besides, the binding of eeh_dev and PCI
device is done while building PCI device I/O cache.

 core

The original EEH implementation is heavily depending on struct pci_dn.
We have to put EEH related information to pci_dn. Actually, we could
split struct pci_dn so that the EEH sensitive information to form an
individual struct, then EEH looks more independent.

The patch replaces pci_dn with eeh_dev for EEH core.

Subject: [PATCH 4624/6423] powerpc/eeh: Replace pci_dn with eeh_dev for EEH
 aux components

The original EEH implementation is heavily depending on struct pci_dn.
We have to put EEH related information to pci_dn. Actually, we could
split struct pci_dn so that the EEH sensitive information to form an
individual struct, then EEH looks more independent.

The patch replaces pci_dn with eeh_dev for EEH aux components like
event and driver. Also, the eeh_event struct has been adjusted for
a little bit since eeh_dev has linked the associated FDT (Flat Device
Tree) node and PCI device. It's not necessary for eeh_event struct to
trace FDT node and PCI device. We can just simply to trace eeh_dev in
eeh_event.

The patch also renames function pcid_name() to eeh_pcid_name(), which
should be missed in the previous patch where the EEH aux components
have been cleaned up.

Subject: [PATCH 4625/6423] powerpc/eeh: Replace pci_dn with eeh_dev for EEH on
 pSeries

The pci_dn has been replaced with eeh_dev. In order to comply with
the rule, the EEH platform implementation on pSeries should also
be adjusted for a little bit so that it will depend on eeh_dev instead
of pci_dn.

The patch replaces pci_dn with eeh_dev. The corresponding information
will be retrieved from eeh_dev instead of pci_dn.

Subject: [PATCH 4626/6423] powerpc/eeh: Introduce struct eeh_stats for EEH

With the original EEH implementation, the EEH global statistics
are maintained by individual global variables. That makes the
code a little hard to maintain.

The patch introduces extra struct eeh_stats for the EEH global
statistics so that it can be maintained in collective fashion.

It's the rework on the corresponding v5 patch. According to
the comments from David Laight, the EEH global statistics have
been changed for a litte bit so that they have fixed-type of
"u64". Also, the format used to print them has been changed to
"%llu" based on David's suggestion. Also, the output format of
EEH global statistics should be kept as intacted according to
Michael's suggestion that there might be tools parsing them.

Subject: [PATCH 4627/6423] powerpc/eeh: pseries platform config space access
 in EEH

With the original EEH implementation, the access to config space of
the corresponding PCI device is done by RTAS sensitive function. That
depends on pci_dn heavily. That would limit EEH extension to other
platforms like powernv because other platforms might have different
ways to access PCI config space.

The patch splits those functions used to access PCI config space
and implement them in platform related EEH component. It would be
helpful to support EEH on multiple platforms simutaneously in future.

Subject: [PATCH 4628/6423] powerpc: Rework lazy-interrupt handling

The current implementation of lazy interrupts handling has some
issues that this tries to address.

We don't do the various workarounds we need to do when re-enabling
interrupts in some cases such as when returning from an interrupt
and thus we may still lose or get delayed decrementer or doorbell
interrupts.

The current scheme also makes it much harder to handle the external
"edge" interrupts provided by some BookE processors when using the
EPR facility (External Proxy) and the Freescale Hypervisor.

Additionally, we tend to keep interrupts hard disabled in a number
of cases, such as decrementer interrupts, external interrupts, or
when a masked decrementer interrupt is pending. This is sub-optimal.

This is an attempt at fixing it all in one go by reworking the way
we do the lazy interrupt disabling from the ground up.

The base idea is to replace the "hard_enabled" field with a
"irq_happened" field in which we store a bit mask of what interrupt
occurred while soft-disabled.

When re-enabling, either via arch_local_irq_restore() or when returning
from an interrupt, we can now decide what to do by testing bits in that
field.

We then implement replaying of the missed interrupts either by
re-using the existing exception frame (in exception exit case) or via
the creation of a new one from an assembly trampoline (in the
arch_local_irq_enable case).

This removes the need to play with the decrementer to try to create
fake interrupts, among others.

In addition, this adds a few refinements:

 - We no longer  hard disable decrementer interrupts that occur
while soft-disabled. We now simply bump the decrementer back to max
(on BookS) or leave it stopped (on BookE) and continue with hard interrupts
enabled, which means that we'll potentially get better sample quality from
performance monitor interrupts.

 - Timer, decrementer and doorbell interrupts now hard-enable
shortly after removing the source of the interrupt, which means
they no longer run entirely hard disabled. Again, this will improve
perf sample quality.

 - On Book3E 64-bit, we now make the performance monitor interrupt
act as an NMI like Book3S (the necessary C code for that to work
appear to already be present in the FSL perf code, notably calling
nmi_enter instead of irq_enter). (This also fixes a bug where BookE
perfmon interrupts could clobber r14 ... oops)

 - We could make "masked" decrementer interrupts act as NMIs when doing
timer-based perf sampling to improve the sample quality.

Signed-off-by-yet: Benjamin Herrenschmidt <benh@kernel.crashing.org>
---

v2:

- Add hard-enable to decrementer, timer and doorbells
- Fix CR clobber in masked irq handling on BookE
- Make embedded perf interrupt act as an NMI
- Add a PACA_HAPPENED_EE_EDGE for use by FSL if they want
  to retrigger an interrupt without preventing hard-enable

v3:

 - Fix or vs. ori bug on Book3E
 - Fix enabling of interrupts for some exceptions on Book3E

v4:

 - Fix resend of doorbells on return from interrupt on Book3E

v5:

 - Rebased on top of my latest series, which involves some significant
rework of some aspects of the patch.

v6:
 - 32-bit compile fix
 - more compile fixes with various .config combos
 - factor out the asm code to soft-disable interrupts
 - remove the C wrapper around preempt_schedule_irq

v7:
 - Fix a bug with hard irq state tracking on native power7

The "max" parameter of 'find_wl_entry()' was documented incorrectly and
it actually means the maximum possible difference from the smallest erase
counter. Rename it to "diff" instead, and amend the documentation.

Subject: [PATCH 4632/6423] UBI: fix eraseblock picking criteria

The 'find_wl_entry()' function expects the maximum difference as the second
argument, not the maximum absolute value. So the "unknown" eraseblock picking
was incorrect, as Shmulik Ladkani spotted. This patch fixes the issue.

Subject: [PATCH 4633/6423] UBI: reduce memory consumption

Remove the pre-allocated 'peb_buf2' buffer because we do not really need it.
The only reason UBI has it is to check that the data were written correctly.
But we do not have to have 2 buffers for this and waste RAM - we can just
compare CRC checksums instead. This reduces UBI memory consumption.

Check /compatible rather than /model to determine the machine name.
The p1022ds older device trees get a different /model from the new
ones, while /compatible is consistent there, so checking /compatible
will save the bother of detecting older p1022ds device trees.

Subject: [PATCH 4640/6423] iommu/amd: Fix double free of mem-region in
 error-path

When ioremap_nocache fails in iommu initialization the code
calls release_mem_region immediatly. But the function is
called again when the propagates into the upper init
functions leading to a double-free. Fix that.

Subject: [PATCH 4641/6423] HID: make it possible to force hid-core claim the
 device

Introduce 'hid_ignore_special_drivers' module parameter that makes hid-core
claim the device even if it's listed in hid_have_special_driver[]. This
is useful mostly for debugging purposes and specialized initrds, where
all the hid drivers are not avaiable.

Subject: [PATCH 4642/6423] GFS2: Clean up log flush header writing

We already send both a pre and post flush to the block device
when writing a journal header. There is no need to wait for
the previous I/O specifically when we do this, unless we've
turned "barriers" off.

As a side effect, this also cleans up the code path for flushing
the journal and makes it more readable.

Subject: [PATCH 4643/6423] GFS2: call gfs2_write_alloc_required for each chunk

gfs2_fallocate was calling gfs2_write_alloc_required() once at the start of
the function. This caused problems since gfs2_write_alloc_required used a
long unsigned int for the len, but gfs2_fallocate could allocate a much
larger amount.  This patch will move the call into the loop where the
chunks are actually allocated and zeroed out. This will keep the allocation
size under the limit, and also allow gfs2_fallocate to quickly skip over
sections of the file that are already completely allocated.

fallcate_chunk was also not correctly setting the file size.  It was using the
len veriable to find the last block written to, but by the time it was setting
the size, the len variable had already been decremented to 0.

Subject: [PATCH 4644/6423] iwlwifi: move command queue number out of the
 iwl_shared struct

The command queue number is required by the transport
layer, but it can be determined only by the op mode.
Move this parameter to the dvm op mode, and configure
the transport layer using an API.

Subject: [PATCH 4645/6423] iwlwifi: restore PAN support

in iwlwifi: move setting up fw parameters

Meenakshi moved code up to configure the transport layer, but this
code read the sku before it was set (from the EEPROM). This killed
P2P.
Only the ucode_flags are needed to configure the transport layer, not
the sku which _must_ be set after the EEPROM is read.

We need to reconfigure the transport in case the EEPROM disabled PAN
support. This is not the nicest thing to do, but we have no choice.
Document that we are allowed to configure the transport several times
before start_fw, but not after.

From 18478e8b626edc2d181dcb1b93e1f99ad72095e9 Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Fri, 9 Mar 2012 17:51:10 +0100
Subject: [PATCH 4648/6423] ALSA: hda - Initialize vmaster slave volumes

When the driver is changed to use vmaster or a new slave element is
added by the improvement of the parser code, user may face often the
silent output because of the muted slave mixer although Master volume
is properly set.  And they complain.  And I get upset.

Although such a mixer element should be initialized via "alsactl init",
it'd be more user-friendly if the known output slaves are unmuted and
set to 0dB so that user can control the volume only with Master as
default.  Since Master is still set muted as default even with this
change, no risk of the speaker blow up, too.

Subject: [PATCH 4653/6423] pch_uart: Use uartclk instead of base_baud

The term "base baud" refers to the fastest baud rate the device can communicate
at. This is clock/16. pch_uart is using base_baud as the clock itself. Rename
the variables to be semantically correct.

Subject: [PATCH 4654/6423] pch_uart: Add Fish River Island II uart clock
 quirks

Add support for the Fish River Island II (FRI2) UART clock following the CM-iTC
quirk handling mechanism. Depending on the firmware installed on the device, the
FRI2 uses a 48MHz or a 64MHz UART clock. This is detected with DMI strings.

Add similar UART clock quirk handling to the pch_console_setup() function to
enable kernel messages on boards with non-standard UART clocks.

Per Alan's suggestion, abstract out UART clock selection into
pch_uart_get_uartclk() to avoid code duplication.

Subject: [PATCH 4655/6423] pch_uart: Add user_uartclk parameter

For cases where boards with non-default clocks are not yet added to the kernel
or when the clock varies across hardware revisions, it is useful to be
able to specify the UART clock on the kernel command line.

Add the user_uartclk parameter and prefer it, if set, to the default and
board specific UART clock settings. Specify user_uartclock on the command-line
with "pch_uart.user_uartclk=48000000".

Subject: [PATCH 4658/6423] serial: delete last unused traces of pausing I/O in
 8250

This is the last traces of pausing I/O that we had back some
twenty years ago.  Probably was only required for 8MHz ISA
cards running "on the edge" at 12MHz.  Anyway it hasn't been
in use for years, so lets just bury it for good.

Subject: [PATCH 4659/6423] serial: make 8250's serial_in shareable to other
 drivers.

Currently 8250.c has serial_in and serial_out as shortcuts
to doing the port I/O.  They are implemented as macros a
ways down in the file.  This isn't by accident, but is
implicitly required, so cpp doesn't mangle other instances
of the common string "serial_in", as it exists as a field
in the port struct itself.

The above mangling avoidance violates the principle of least
surprise, and it also prevents the shortcuts from being
relocated up to the top of file, or into 8250.h -- either
being a better location than the current one.

Move them to 8250.h so other 8250-like drivers can also use
the shortcuts, and in the process, make the conflicting
names go away by using static inlines instead of macros.
The object file size remains unchanged with this modification.

Subject: [PATCH 4660/6423] serial: delete useless void casts in 8250.c

These might have worked some magic with an ancient gcc back in
1992, but "objdump --disassemble" on gcc 4.6 on x86-64 shows
identical output before and after this commit.  Send the casts
and their hysterical rasins to the bitbucket.

Subject: [PATCH 4661/6423] serial: reduce number of indirections in 8250 code

The serial_8250_port struct contains within a serial_port struct
and many times one or the other, or both are in scope within
functions via a passed in arg, or via container_of.

However there are a lot of cases where we have access directly
to the port pointer, but yet go through the parent 8250_port
structure instead to get it.  These should just use the port
struct directly.

Similarly there are cases where it makes sense (from a code
cleanliness point of view) to declare a local for the port
struct, so we aren't going through the parent 8250_port struct
repeatedly to get to it.

We get a small reduction in text size, but it appears that
gcc was smart enough to internally be doing most of this
already, so the readability improvement is the larger gain.

Subject: [PATCH 4662/6423] serial: introduce generic port in/out helpers

Looking at the existing serial drivers (esp. the 8250 derived
variants) we see a common trend.  They create a hardware specific
port struct, which in turn contains a generic serial_port struct.

The other trend, is that they all create some sort of shortcut
to go through the hardware specific struct, to the serial_port
struct, which has the basic in/out operations within.  Looking
for the serial_in and serial_out in several drivers shows this.

Rather than let this continue, lets create a generic set of
similar helper wrappers that can be used on a struct port, so
we can eliminate bouncing out through hardware specific struct
pointers just to come back into struct port where possible.

Subject: [PATCH 4663/6423] serial: use serial_port_in/out vs serial_in/out in
 8250

The serial_in and serial_out helpers are expecting to operate
on an 8250_port struct.  These in turn go after the contained
normal port struct which actually has the actual in/out accessors.

But what is happening in some cases, is that a function is passed
in a port struct, and it runs container_of to get the 8250_port
struct, and then it uses serial_in/out helpers on that.  But when
you do, it goes full circle, since it jumps back inside the 8250_port
to find the contained port struct (which we already knew!).

So, if we are operating in a scope where we know the struct port,
then use the serial_port_in/out helpers and avoid the bouncing
around.  If we don't have the struct port handy, and it isn't
worth making a local for it, then just leave things as-is which
uses the serial_in/out helpers that will resolve the 8250_port
onto the struct port.

Mostly, gcc figures this out on its own -- so this doesn't bring to
the table any revolutionary runtime delta.  However, it is somewhat
misleading to always hammer away on 8250 structs, when the actual
underlying property isn't at all 8250 specific -- and this change
makes that clear.

Subject: [PATCH 4664/6423] serial: remove back and forth conversions in
 serial_out_sync

The two callers to serial_out_sync() have a struct port right
there in scope, but then pass in a struct 8250_port which then
is locally resolved back to a struct port.

Delete the needless back and forth and just pass in the struct
port directly.  Rename the function to have "_port" in its
name, so the name <--> args relationship is consistent with the
other serial_in/out vs serial_port_in/out function classes.

Subject: [PATCH 4665/6423] net: usb: qmi_wwan: New driver for Huawei QMI based
 WWAN devices
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some WWAN LTE/3G devices based on chipsets from Qualcomm provide
near standard CDC ECM interfaces in addition to the usual serial
interfaces.   The Huawei E392/E398 are examples of such devices.

These typically cannot be fully configured using AT commands
over a serial interface.  It is necessary to speak the proprietary
Qualcomm MSM Interface (QMI) protocol to the device to enable the
ethernet proxy functionality.

The devices embed the QMI protocol in CDC on the control interface,
using standard CDC commands and notifications. The do not otherwise
use CDC commands for the ethernet function.  This driver does
therefore not need access to any other aspects of the control
interface than the descriptors attached to it.

Another driver, cdc-wdm, will provide userspace access to the
QMI protocol independently of this driver.  To facilitate this,
this driver avoids binding to the control interface, and uses
only the associated data interface after parsing the common CDC
functional descriptors on the control interface.

You will want both the cdc-wdm and option drivers as companions to
this driver, to have full access to all interfaces and protocols
exported by the device.

Use the new cdc-wdm subdriver interface to create a device management
device even for USB devices having a single combined QMI/wwan USB
interface with three endpoints (int, bulk in, bulk out) instead of
separate data and control interfaces.

Some Huawei devices can be switched to a single interface mode for
use with other operating systems than Linux.  This adds support
for these devices when they run in such non-Linux modes.

Subject: [PATCH 4667/6423] net: qmi_wwan: add Gobi and Pantech UML290 device
 IDs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adding the Pantech UML290 and all non-QDL Gobi device IDs from the
qcserial driver now that we have support for shared net/QMI USB
interfaces.  Most of these are not yet tested with this driver, but
should be mostly identical to tested devices, except for device IDs.

Gobi devices provide several different interfaces (serial/net/other)
using the exact same class, subclass and protocol values.  This driver
will only support the net/QMI function while there are other drivers
supporting other device functions. The net/QMI interface number may
also differ from device to device.  It has been noted that all the
other interfaces have additional functional descriptors, so we use that
to detect the interface supported by this driver.

Subject: [PATCH 4669/6423] staging: ram_console: Fix section mismatches

WARNING: vmlinux.o(.text+0xfcf6e): Section mismatch in reference
from the function ram_console_driver_probe() to the function
.init.text:persistent_ram_init_ringbuffer()
The function ram_console_driver_probe() references
the function __init persistent_ram_init_ringbuffer().
This is often because ram_console_driver_probe lacks a __init
annotation or the annotation of persistent_ram_init_ringbuffer is
wrong.

Move this driver to platform_driver_probe() because ram console
devices aren't going to be added and removed at runtime. Also
shorten the probe function name since driver is redundant and
makes the function name long.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

binder_update_page_range could read freed memory if the vma of the
selected process was freed right before the check that the vma
belongs to the mm struct it just locked.

If the vm_mm pointer in that freed vma struct had also been rewritten
with a value that matched the locked mm struct, then the code would
proceed and possibly modify the freed vma.

Subject: [PATCH 4675/6423] staging: tidspbridge: remove disp_init() and
 disp_exit()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The disp module has a disp_init() and a disp_exit() whose only purpose
is to keep a reference counting which is not used at all.

This patch removes these functions and the reference count variable.

There is no functional changes.

Subject: [PATCH 4686/6423] staging: tidspbridge: remove ref counting in nldr.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The nldr module has a nldr_init() and a nldr_exit() whose only purpose
is to keep a reference counting which is not used at all.

This patch only removes the reference count variable, but not the
functions, because they are used through an interface.

There is no functional changes.

The dynamic loader was called by node.c with an interface. This interface was
also modified to avoid the use of nldr_init() and nldr_exit().

There is not functional changes.

Subject: [PATCH 4691/6423] spi: Mark spi_register_board_info() __devinit

Some systems have SPI devices located on plugin modules which are
enumerated at runtime as devices. The drivers for these plugin modules
need to register their SPI devices at probe() time so want to be able
to call spi_register_board_info() but that function is currently marked
as __init rather than __devinit so this usage isn't legal. Change the
annotation to __devinit to handle this.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fix for:
drivers/spi/spi-topcliff-pch.c: In function ‘pch_spi_handler_sub’:
drivers/spi/spi-topcliff-pch.c:325:17: warning: ‘bpw_len’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘rx_index’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘tx_index’ may be
  used uninitialized in this function [-Wuninitialized]

Move usage of tx_index, rx_index and bpw_len into the same
block as where they are set to prevent uninitialized usage.

v2: instead of init variables with 0 move the whole block

Currently, when spi-topcliff-pch receives transmit request over 4KByte,
this driver can't process correctly. This driver needs to divide the data
into 4Kbyte unit.
This patch fixes the issue.

Subject: [PATCH 4710/6423] spi: Compatibility with direction which is used in
 samsung DMA operation

I found that there are two kind of direction type.
First one is dma_data_direction defined in include/linux/dma-direction.h.
It is used for parameter of dma_map/unmap_single in spi-s3c64xx.
The other one is dma_transter_direction defined in include/linux/dmaengine.h.
It is used for direction of samsung DMA operation
(arch/arm/plat-samsung/dma-ops.c).
This patch is just some changes to use direction defines
which is used in samsung DMA operation.

- * This module implements the virtual ethernet device for iSeries LPAR
- * Linux.  It uses hypervisor message passing to implement an
- * ethernet-like network device communicating between partitions on
- * the iSeries.
- *
- * The iSeries LPAR hypervisor currently allows for up to 16 different
- * virtual ethernets.  These are all dynamically configurable on
- * OS/400 partitions, but dynamic configuration is not supported under
- * Linux yet.  An ethXX network device will be created for each
- * virtual ethernet this partition is connected to.
- *
- * - This driver is responsible for routing packets to and from other
- *   partitions.  The MAC addresses used by the virtual ethernets
- *   contains meaning and must not be modified.
- *
- * - Having 2 virtual ethernets to the same remote partition DOES NOT
- *   double the available bandwidth.  The 2 devices will share the
- *   available hypervisor bandwidth.
- *
- * - If you send a packet to your own mac address, it will just be
- *   dropped, you won't get it on the receive side.
- *
- * - Multicast is implemented by sending the frame frame to every
- *   other partition.  It is the responsibility of the receiving
- *   partition to filter the addresses desired.
- *
- * Tunable parameters:
- *
- * VETH_NUMBUFFERS: This compile time option defaults to 120.  It
- * controls how much memory Linux will allocate per remote partition
- * it is communicating with.  It can be thought of as the maximum
- * number of packets outstanding to a remote partition at a time.

Subject: [PATCH 4716/6423] intel, gma500, lvds: Fix use after free and mem
 leak in psb_intel_lvds_init()

In psb_intel_lvds_init(), if we fail to allocate memory for
'psb_intel_connector' we free the memory we previously allocated for
'psb_intel_encoder', but we then proceed to use that free'd pointer
when we do 'psb_intel_encoder->dev_priv = lvds_priv;'.

We may also leak the memory we allocated for 'psb_intel_encoder' if we
'goto failed_connector;' and the variable goes out of scope.

While I was there anyway, I also removed the pointless 'if
(psb_intel_connector)' before freeing it at the 'failed_connector:'
label - kfree() deals gracefully with NULL pointers, so it is not
needed.

From 026abc333205c1fff80138b8c2cac3d0347685f4 Mon Sep 17 00:00:00 2001
From: "Kirill A. Shutemov" <kirill.shutemov@linux.intel.com>
Date: Thu, 8 Mar 2012 16:02:20 +0000
Subject: [PATCH 4720/6423] gma500: initial medfield merge

We need to merge this ahead of some of the cleanup because a lot of needed
cleanup spans both new and old chips. If we try and clean up and the merge
we end up fighting ourselves.

Signed-off-by: Kirill A. Shutemov <kirill.shutemov@linux.intel.com>
[With a load of the cleanup stuff folded in, register stuff reworked sanely]

Subject: [PATCH 4759/6423] firewire: sbp2: replace a GFP_ATOMIC allocation

sbp2_send_management_orb() is called by sbp2_login, sbp2_reconnect, and
sbp2_remove, all which are able to sleep during memory allocations.
Actually, sbp2_send_management_orb() itself is a sleeping function.

Login and remove could allocate with GFP_KERNEL but reconnect needs
GFP_NOIO to ensure progress in low memory situations.

Subject: [PATCH 4760/6423] firewire: tone down some diagnostic log messages

The "skipped bus generations" message was added together with the
respective fw_device retaining/ reviving code in order to see how it all
works out.  It did well, so don't spam the log anymore.

The "register access failure" situation still needs an actual handler.
But at this point it makes less sense to ask folks to send mails about
it.  We now have a pretty good picture of what controllers emit this and
when:

CONFIG_FIREWIRE_OHCI_DEBUG could have been exposed to kernel tweakers
if CONFIG_EXPERT was set.  But in hindsight, this stuff is far too
useful to omit it.  So get rid of two #else branches that are only
going to bitrot otherwise.

Subject: [PATCH 4762/6423] NFSv4.0: Re-establish the callback channel on
 NFS4ERR_CB_PATHDOWN

When the NFSv4.0 server tells us that it can no-longer talk to us
on the callback channel, we should attempt a new SETCLIENTID in
order to re-transmit the callback channel information.

Note that as long as we do not change the boot verifier, this is
a safe procedure; the server is required to keep our state.

Also move the function nfs_handle_cb_pathdown to fs/nfs/nfs4state.c,
and change the name in order to mark it as being specific to NFSv4.0.

 boot_option_idle_override.

We needed that call in the past to force the kernel to use
default_idle (which called safe_halt, which called xen_safe_halt).

But set_pm_idle_to_default() does now that, so there is no need
to use this boot option operand.

Subject: [PATCH 4764/6423] xen/enlighten: Expose MWAIT and MWAIT_LEAF if
 hypervisor OKs it.

For the hypervisor to take advantage of the MWAIT support it needs
to extract from the ACPI _CST the register address. But the
hypervisor does not have the support to parse DSDT so it relies on
the initial domain (dom0) to parse the ACPI Power Management information
and push it up to the hypervisor. The pushing of the data is done
by the processor_harveset_xen module which parses the information that
the ACPI parser has graciously exposed in 'struct acpi_processor'.

For the ACPI parser to also expose the Cx states for MWAIT, we need
to expose the MWAIT capability (leaf 1). Furthermore we also need to
expose the MWAIT_LEAF capability (leaf 5) for cstate.c to properly
function.

The hypervisor could expose these flags when it traps the XEN_EMULATE_PREFIX
operations, but it can't do it since it needs to be backwards compatible.
Instead we choose to use the native CPUID to figure out if the MWAIT
capability exists and use the XEN_SET_PDC query hypercall to figure out
if the hypervisor wants us to expose the MWAIT_LEAF capability or not.

Note: The XEN_SET_PDC query was implemented in c/s 23783:
"ACPI: add _PDC input override mechanism".

With this in place, instead of
 C3 ACPI IOPORT 415
we get now
 C3:ACPI FFH INTEL MWAIT 0x20

Note: The cpu_idle which would be calling the mwait variants for idling
never gets set b/c we set the default pm_idle to be the hypercall variant.

Subject: [PATCH 4774/6423] target: Convert session_lock to irqsave

This patch converts the remaining struct se_portal_group->session_lock
usage to use irqsave+irqrestore to address the following warnings for
hardware target mode interrupt context usage.  This change generate
other warnings for current iscsi-target mode still using ->session_lock
with spin_lock_bh, which will need to be converted in a seperate patch.

Subject: [PATCH 4776/6423] NFS: remove nfs_inode radix tree

The radix tree is only being used to compile lists of reqs needing commit.
It is simpler to just put the reqs directly into a list.

This patch adds basic se_session->sess_kref and get/put helpers for fabric
session reference counting.  It sets the initial kref in transport_init_session()
and adds a target_release_session() callback to invoke TFO->close_session()
for final session shutdown.

Subject: [PATCH 4782/6423] target: Add se_node_acl->acl_free_comp for NodeACL
 release path

Add se_node_acl->acl_free_comp for NodeACL release path to wait for outstanding
fabric session shutdown to complete in transport_deregister_session() before
finishing NodeACL release from configfs process context.

Also make transport_deregister_session() clear the comp_nacl bit
to skip se_node_acl->acl_free_comp completion for dynamically generated
NodeACL during fabric session shutdown.

Subject: [PATCH 4783/6423] target: Add se_node_acl->acl_kref for
 ->acl_free_comp usage

This patch adds se_node_acl->acl_kref for use with ->acl_free_comp
during explict se_node_acl release.  It adds kref_init() during
se_node_acl setup, kref_get() during __transport_register_session()
-> target_put_nacl() with existing transport_deregister_session()
fabric callback usage.

It also moves transport_free_session() to release *se_sess memory
after target_put_nacl() execution in transport_deregister_session()

Subject: [PATCH 4784/6423] target: Convert se_node_acl->acl_group removal to
 use ->acl_kref

This patch converts core_tpg_del_initiator_node_acl() shutdown from configfs
context to use se_node_acl->acl_kref and ->acl_free_comp in order to wait for
outstanding fabric callbacks to complete via transport_deregister_session()
callbacks before waking ->acl_free_comp from the last ->acl_kref put.

It also changes core_tpg_del_initiator_node_acl() to setup a local sess_list
with target_get_session() + acl->acl_stop = 1 for active sessions that will
be shutdown, and changes transport_deregister_session_configfs() to check
for ->acl_stop usage.

Subject: [PATCH 4785/6423] iscsi-target: Convert to use target_put_session +
 sess_kref

This patch converts iscsi-target session code to use se_sess->sess_kref
counting for iscsi session shutdown.  The following cases include:

*) last iscsit_close_connection() shutdown path to invoke close session
*) iscsit_logout_post_handler_closesession() for explict logout
*) iscsit_free_session() caller for explict shutdown

It also moves iscsit_stop_session() call from lio_tpg_close_session()
into lio_tpg_shutdown_session() TFO callbacks to invoke an explict
shutdown, and also changes iscsi_check_for_session_reinstatement()
login code to use se_sess->sess_kref.

(v2: Make iscsit_handle_time2retain_timeout() use target_put_session)

From c7ec05c82bfd6acf1fd800d628591500805f3179 Mon Sep 17 00:00:00 2001

Subject: [PATCH 4786/6423] target: Drop unused legacy target_core_fabric_ops
 API callers

This patch drops the following unused legacy API callers from target_core_fabric.h:

*) TFO->fall_back_to_erl0()
*) TFO->stop_session()
*) TFO->sess_logged_in()
*) TFO->is_state_remove()

This patch also removes the stub usage in loopback, tcm_fc, iscsi_target,
and ib_srpt fabric modules.

Subject: [PATCH 4787/6423] tcm_fc: Fix fc_exch memory leak in
 ft_send_resp_status

This patch fixes a bug in tcm_fc where fc_exch memory from fc_exch_mgr->ep_pool
is currently being leaked by ft_send_resp_status() usage.  Following current
code in ft_queue_status() response path, using lport->tt.seq_send() needs to be
followed by a lport->tt.exch_done() in order to release fc_exch memory back into
libfc_em kmem_cache.

ft_send_resp_status() code is currently used in pre submit se_cmd ft_send_work()
error exceptions, TM request setup exceptions, and main TM response callback
path in ft_queue_tm_resp().  This bugfix addresses the leak in these cases.

[Fix for breakage which will be introduced during the merge window via

Subject: [PATCH 4794/6423] NFS: replace global bl_wq with per-net one

This queue is used for sleeping in kernel and it have to be per-net since we
don't want to wake any other waiters except in out network nemespace.
BTW, move wq to per-net data is easy. But some way to handle upcall timeouts
have to be provided. On message destroy in case of timeout, tasks, waiting for
message to be delivered, should be awakened. Thus, some data required to
located the right wait queue. Chosen solution replaces rpc_pipe_msg object with
new introduced bl_pipe_msg object, containing rpc_pipe_msg and proper wq.

Subject: [PATCH 4795/6423] [S390] Fix gcc 4.6.0 compile warning

With gcc 4.6.0 we get a false compile warning:

 arch/s390/kernel/setup.c: In function 'setup_arch':
 arch/s390/kernel/setup.c:767:3: warning: 'msg' may be used
            uninitialized in this function [-Wuninitialized]
 arch/s390/kernel/setup.c:753:8: note: 'msg' was declared here

This patch makes gcc quiet.

Subject: [PATCH 4796/6423] [S390] rename lowcore field

The 16 bit value at the lowcore location with offset 0x84 is the
cpu address that is associated with an external interrupt. Rename
the field from cpu_addr to ext_cpu_addr to make that clear.

Subject: [PATCH 4797/6423] [S390] rework smp code

Define struct pcpu and merge some of the NR_CPUS arrays into it, including
__cpu_logical_map, current_set and smp_cpu_state. Split smp related
functions to those operating on physical cpus and the functions operating
on a logical cpu number. Make the functions for physical cpus use a
pointer to a struct pcpu. This hides the knowledge about cpu addresses in
smp.c, entry[64].S and swsusp_asm64.S, thus remove the sigp.h header.

The PSW restart mechanism is used to start secondary cpus, calling a
function on an online cpu, calling a function on the ipl cpu, and for
the nmi signal. Replace the different assembler functions with a
single function restart_int_handler. The new entry point calls a function
whose pointer is stored in the lowcore of the target cpu and it can wait
for the source cpu to stop. This covers all existing use cases.

Overall the code is now simpler and there are ~380 lines less code.

- * one which is causing all the confusion with __cpu_logical_map and

From 4c1051e37a0e2a941115c6fb7ba08c318f25a0f9 Mon Sep 17 00:00:00 2001
From: Martin Schwidefsky <schwidefsky@de.ibm.com>
Date: Sun, 11 Mar 2012 11:59:27 -0400
Subject: [PATCH 4798/6423] [S390] rework idle code

Whenever the cpu loads an enabled wait PSW it will appear as idle to the
underlying host system. The code in default_idle calls vtime_stop_cpu
which does the necessary voodoo to get the cpu time accounting right.
The udelay code just loads an enabled wait PSW. To correct this rework
the vtime_stop_cpu/vtime_start_cpu logic and move the difficult parts
to entry[64].S, vtime_stop_cpu can now be called from anywhere and
vtime_start_cpu is gone. The correction of the cpu time during wakeup
from an enabled wait PSW is done with a critical section in entry[64].S.
As vtime_start_cpu is gone, s390_idle_check can be removed as well.

Subject: [PATCH 4800/6423] [S390] zfcpdump: Implement async sdias event
 processing

There are two different ways to do the "store data in absolute
storage" SCLP event processing, synchronous and asynchrounous.
This patch adds the asynchronous variant.

Subject: [PATCH 4801/6423] [S390] irq: set __ARCH_IRQ_EXIT_IRQS_DISABLED

Set __ARCH_IRQ_EXIT_IRQS_DISABLED in order to optimize irq_exit() a
bit, since we call __do_softirq() instead of do_softirq().
This saves several needless checks, pointless interrupt disabling
and an extra branch.
If do_softirq() gets called from process context we still switch to
the async stack.

Subject: [PATCH 4802/6423] [S390] irq: external interrupt code passing

The external interrupt handlers have a parameter called ext_int_code.
Besides the name this paramter does not only contain the ext_int_code
but in addition also the "cpu address" (POP) which caused the external
interrupt.
To make the code a bit more obvious pass a struct instead so the called
function can easily distinguish between external interrupt code and
cpu address. The cpu address field however is named "subcode" since
some external interrupt sources do not pass a cpu address but a
different parameter (or none at all).

From 3ab121ab18669226742891416fe7ecc86dadb047 Mon Sep 17 00:00:00 2001
From: Michael Holzheu <holzheu@linux.vnet.ibm.com>
Date: Sun, 11 Mar 2012 11:59:32 -0400
Subject: [PATCH 4803/6423] [S390] kernel: Add z/VM LGR detection

Currently the following mechanisms are available to move active
Linux on System z instances between machines:
* z/VM 6.2 SSI (Single System Image)
* Suspend/resume
For moving Linux instances in this patch the term LGR (Linux Guest
Relocation) is used. Because such an operation is critical, it
should be detectable from Linux. With this patch for both, a live
system and a kernel dump, the information about LGRs is accessible.
To identify a guest, stsi and stfle data is used. A new function
lgr_info_log() compares the current data (lgr_info_cur) with the
last recorded one (lgr_info_last). In case the two data sets differ,
lgr_info_cur is logged to the "lgr" s390dbf.

The following trigger points call lgr_info_log():
* panic
* die
* kdump
* LGR timer
* PSW restart
* QDIO recovery
* resume

This patch also changes the s390dbf hex_ascii view. Now only printable ASCII
characters are shown.

Date: Sun, 11 Mar 2012 11:59:33 -0400
Subject: [PATCH 4804/6423] [S390] Use block_sigmask()

Use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures.

In the past some architectures got this code wrong, so using this
helper function should stop that from happening again.

Subject: [PATCH 4805/6423] [S390] kernel: Add OS info memory interface

In order to allow kdump based stand-alone dump, some information
has to be passed from the old kernel to the new dump kernel. This
is done via a the struct "os_info" that contains the following fields:
 * crashkernel base and size
 * reipl block
 * vmcoreinfo
 * init function
A pointer to os_info is stored at a well known storage location
and the whole structure as well as all fields are secured with
checksums.

Subject: [PATCH 4809/6423] [S390] Ensure that vmcore_info pointer is never
 accessed directly

Because the vmcore_info pointer is not 8 byte aligned it never should
not be accessed directly. The reason is that the compiler assumes that
64 bit pointer are always double word aligned. To ensure save access,
the vmcore_info type in struct lowcore is changed from u64 to an u8[8]
array and a comment is added.

Subject: [PATCH 4810/6423] device.h: cleanup users outside of linux/include (C
 files)

For files that are actively using linux/device.h, make sure
that they call it out.  This will allow us to clean up some
of the implicit uses of linux/device.h within include/*
without introducing build regressions.

Yes, this was created by "cheating" -- i.e. the headers were
cleaned up, and then the fallout was found and fixed, and then
the two commits were reordered.  This ensures we don't introduce
build regressions into the git history.

Subject: [PATCH 4811/6423] NFS: Fix a number of sparse warnings

Fix a number of "warning: symbol 'foo' was not declared. Should it be
static?" conditions.

Fix 2 cases of "warning: Using plain integer as NULL pointer"

fs/nfs/delegation.c:263:31: warning: restricted fmode_t degrades to integer
  - We want to allow upgrades to a WRITE delegation, but should otherwise
    consider servers that hand out duplicate delegations to be borken.

Subject: [PATCH 4812/6423] regulator: twl6030: Fix voltage selection logic

The voltage selection logic for the twl6030 smps fails if
min:max is such that min < 1300mV and max > 1300mV although
this is in valid range for a regulator e.g. [x, 1350] where
x < 1300.
Fixing the voltage selection logic such that first it will
check for min_uV for a range and then calculated value will
be checked against max_uV.

Subject: [PATCH 4813/6423] regulator: twl4030: add support for external
 voltage get/set

This is needed for SMPS regulators, which use the OMAP voltage
processor for voltage get/set functions instead of the normal I2C
channel. For this purpose, regulator_init_data->driver_data contents
are expanded, it is now a struct which contains function pointers
for the set/get voltage operations, a data pointer for these, and
the previously used features bitmask.

regulator voltages can only be controlled through the smartreflex
voltage channel, thus the support for the voltage_get and set is
minimal and requires external controller.

From 2098e95ce9bb039ff2e7bf836df358d18a176139 Mon Sep 17 00:00:00 2001
From: Rajendra Nayak <rnayak@ti.com>
Date: Tue, 28 Feb 2012 15:09:11 +0530
Subject: [PATCH 4815/6423] regulator: twl: adapt twl-regulator driver to dt

Modify the twl regulator driver to extract the regulator_init_data from
device tree when passed, instead of getting it through platform_data
structures (on non-DT builds)

Also add documentation for TWL regulator specific bindings.

Subject: [PATCH 4816/6423] regulator: twl-regulator: Add fixed LDO for V1V8,
 V2V1 supply

V1V8 supply most common use is to provide VIO for the system.
V2V1 supply is used on SDP4430/PandaBoards to provide 2.1V to
twl6040, and also as an input to VCXIO_IN, VDAC_IN of twl6030.

Also update the bindings documentation with the new compatible
property for these additional LDOs.

Subject: [PATCH 4821/6423] regulator: tps65910: Correct VIO voltage
 configuration

The VIO regulator register specify the voltage configuration
on bit3:2 of its register. And hence only these bits should
be modified when setting voltage and used when reading voltage
from register setting.

Subject: [PATCH 4824/6423] regulator: Convert ab8499 to use get_voltage_sel()

This change is required to make ab8500_regulator_get_voltage_sel work.
The regulator core will call set_voltage_time_sel only when get_voltage_sel is
implemented.

Subject: [PATCH 4826/6423] regulator: Fix the logic of
 s5m8767_set_voltage_time_sel

This patch includes below fixes:
1. The mask variable is not used at all here, remove it.
2. We already have the new_sel and old_sel, simply returns the delay by:
  DIV_ROUND_UP(desc->step * (new_sel - old_sel), s5m8767->ramp_delay);

Subject: [PATCH 4827/6423] regulator: Fix n_voltage settings for pcf50633
 regulator
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Current code has off-by-one n_voltage settings for AUTO/DOWN*/LDO* regulators.

Take ldo1 as example:
n_voltage should be (3.6 - 0.9) / 0.1 + 1 = 28

Table 76. LDO1OUT - LDO1 output voltage select register (address 2Dh) bit description[1]
Bit Symbol Access Description
4:0 ldo1_out R/W VO(prog) = 0.9 + ldo1_out × 0.1 V (max 3.6V); e.g.
00000 : 0.9 V
00001 : 1.0 V
11000 : 3.3 V
11011 : 3.6 V
11111 : 3.6 V

The n_voltage settings for HCLDO and MEMLDO are also wrong.
n_voltage for HCLDO and MEMLDO should be (3.6 - 0.9) / 0.1 + 1 = 28

Table 88. HCLDOOUT - HCLDO output voltage select register (addr. 39h) bit description[1]
Bit Symbol Access Description
4:0 hcldo_out R/W VO(prog) = 0.9 + hcldo_out × 0.1 V (max 3.6 V); e.g.
00000 : 0.9 V
00001 : 1.0 V
11011 : 3.6 V
11111 : 3.6 V

Table 62. MEMLDOOUT - MEMLDO o/p voltage select reg. (address 26h) bit description[1]
Bit Symbol Access Description
4:0 memldo_out R/W VO(prog) = 0.9 + memldo_out × 0.1 V; e.g.
00000: 0.9 V
00001: 1.0 V
11000 : 3.3 V
11011 : 3.6 V
11111 : 3.6 V

Subject: [PATCH 4831/6423] regulator: Add a pointer to aat2870_data in struct
 aat2870_regulator

The reason we add *pdev in struct aat2870_regulator is to use it
to get a pointer to struct aat2870_data.
Save a pointer to struct aat2870_data instead of pdev in struct
aat2870_regulator, this change makes the intention more clear.

Subject: [PATCH 4843/6423] regulator: tps65910: Sleep off rails when ext sleep
 configured

Keep the rails OFF in sleep mode only when the rails are
controlled by external sleep control.
The devices tps65910 and tps65911, both has the sleep input.
The tps65911's sleep input is not same as tps65910's EN3 and hence
taking care of SLEEP input as separate external sleep control input.

ramp_delay is usec unit. So 1000 should be multiplied.

Subject: [PATCH 4848/6423] regulator: Rename s5m8767_convert_voltage to
 s5m8767_convert_voltage_to_sel

This function finds the smallest voltage that falls within the specified range,
and then returns the selector. This rename makes the intention more clear.

Also remove unneeded local variables min_vol and max_vol in s5m8767_set_voltage
and s5m8767_set_voltage_buck.

Content-Transfer-Encoding: 8bit

Kill faulty checks on flow-off leading to connection drop at race conditions.
caif_socket checks for flow-on before transmitting and goes to sleep or
return -EAGAIN upon flow stop. Remove faulty subsequent checks on flow-off
leading to connection drop. Also fix memory leaks on some of the errors paths.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Connection ID configured through RTNL must allow zero as
connection id. If connection-id is not given when creating the
interface, configure a loopback interface using ifindex as
connection-id.

Subject: [PATCH 4856/6423] ipv6: Fix Smatch warning.

With commit d6ddef9e641d(IPv6: Fix not join all-router mcast group
when forwarding set.) I check 'dev' after it's dereference that
leads to a Smatch complaint:

net/ipv6/addrconf.c:438 ipv6_add_dev()
	 warn: variable dereferenced before check 'dev' (see line 432)

net/ipv6/addrconf.c
   431		/* protected by rtnl_lock */
   432		rcu_assign_pointer(dev->ip6_ptr, ndev);
                                   ^^^^^^^^^^^^
Old dereference.

   433
   434		/* Join all-node multicast group */
   435		ipv6_dev_mc_inc(dev, &in6addr_linklocal_allnodes);
   436
   437		/* Join all-router multicast group if forwarding is set
*/
   438		if (ndev->cnf.forwarding && dev && (dev->flags &
IFF_MULTICAST))
                                            ^^^

Remove the check to avoid the complaint as 'dev' can't be NULL.

Make a bunch of variables in net/sunrpc/xprtsock.c static

Fix a couple of "warning: symbol 'foo' was not declared. Should it be
static?" reports.

Fix a couple of conflicting function declarations.

Subject: [PATCH 4858/6423] net: get rid of some pointless casts to sockaddr
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The following 4 functions:
  move_addr_to_kernel
  move_addr_to_user
  verify_iovec
  verify_compat_iovec
are always effectively called with a sockaddr_storage.

Make this explicit by changing their signature.

This removes a large number of casts from sockaddr_storage to sockaddr.

From: Joe Perches <joe@perches.com>
Date: Sun, 11 Mar 2012 18:36:11 +0000
Subject: [PATCH 4859/6423] net: Convert printks to pr_<level>

Use a more current kernel messaging style.

Convert a printk block to print_hex_dump.
Coalesce formats, align arguments.
Use %s, __func__ instead of embedding function names.

Some messages that were prefixed with <foo>_close are
now prefixed with <foo>_fini.  Some ah4 and esp messages
are now not prefixed with "ip ".

The intent of this patch is to later add something like
  #define pr_fmt(fmt) "IPv4: " fmt.
to standardize the output messages.

Text size is trivially reduced. (x86-32 allyesconfig)

Subject: [PATCH 4860/6423] ath6kl: Fix merge error in ath6kl_set_ies()

Portion of the commit id 080eec4fb4 ("ath6kl: Clear the IE in firmware
if not set") was overwritten by mistake due to a merge
conflict. This patch fixes the code back to how it should be.

Subject: [PATCH 4862/6423] HID: multitouch: fix handling of buggy reports
 descriptors for Dell ST2220T

LG multitouch panels, such as the one found in Dell ST2220T, has buggy
reports descriptors. With the previous implementation, it was impossible
to rely on the reports descriptors to determine how the different
touches are emitted from the device.

This patch changes the splitting of the different touches in the report
in a more robust way.

Subject: [PATCH 4863/6423] HID: handle all multitouch devices through
 hid-multitouch

When the quirk HID_QUIRK_MULTITOUCH is present and when hid-multitouch
is loaded, let's pass the device to hid-multitouch even if it has
not been registered in hid-multitouch.

If any other driver wants to take precedence over hid-multitouch,
the usual way of adding it to hid_have_special_driver will work as
the quirk HID_QUIRK_MULTITOUCH won't be set by the generic hid layer.

Most callback functions implementation for tps65217_pmic_ldo234_ops and

This patch uses tps65217_pmic_ops for all DCDCx, LDO2, LDO3, and LDO4.

Subject: [PATCH 4867/6423] HID: multitouch: detect serial protocol

Microsoft's documentation about multitouch protocols tells that
if a device presents one touch per report, then it should be treated
as a serial protocol.

Subject: [PATCH 4868/6423] ALSA: Add a hook capability to vmaster controls

This patch adds a hook to vmaster control to be called at each time
when the master value is changed.  It'd be handy for an additional
mute LED control following the Master switch, for example.

Subject: [PATCH 4870/6423] ARM: OMAP: mcbsp: Convert core driver to proper
 platform driver

Convert the plat-omap/mcbsp.c driver to be proper platform driver.
Remove the omap_mcbsp_init function call which was called from
mach-omap1/2/mcbsp.c to register the platform driver for the just
created platform device in the same function.

From 45656b44f6d1968d838f3abcf3a264ee9fa2fc62 Mon Sep 17 00:00:00 2001
From: Peter Ujfalusi <peter.ujfalusi@ti.com>
Date: Tue, 14 Feb 2012 18:20:58 +0200
Subject: [PATCH 4873/6423] ASoC: omap-mcbsp: Create a single driver for McBSP

The OMAP McBSP driver stack used to contain two different
drivers. One of them was used as kind low-level access to
the IP, while the other driver was the ASoC DAI driver.
There were global, shared structures, in different places,
the McBSP instances are reffered with id numbers (sometimes
0 based, in other cases 1 based id numbers).

Create one single driver for OMAP McBSP with name: omap-mcbsp.
Convert the old omap-mcbsp driver initially to be a library
for the omap-mcbsp DAI driver. With this change we can get rid
of all global variables, structures.

Further cleanup is coming...

Subject: [PATCH 4877/6423] ASoC: omap-mcbsp: Cleanup of module probe/remove
 code

Use devm_* where it is possible to save on cleanup path.
Start merging the two mcbsp file content.
Move pm_runtime_enable/disable calls to ASoC probe, remove from module
probe/remove time.

Subject: [PATCH 4879/6423] ASoC: omap-mcbsp: Simplify DMA configuration

Configure the DMA request line, port address, and stream name at
probe time instead of every time we start a stream.
These settings are static in the system.

Subject: [PATCH 4882/6423] ASoC: omap-mcbsp: Configure wakeup in later phase

Configure the WAKEUPEN register at the same time we configure the rest of
the McBSP registers.
In case of OMAP3+, if the sysclock has been reconfigured we are going to
disable McBSP for the duration of the clock change, which will reset the
McBSP registers. The WAKEUPEN register need to be configured later, so
the changes will be effective during runtime.

Subject: [PATCH 4883/6423] ASoC: omap-mcbsp: When closing the port select PRCM
 source for CLKS signal

If external source for the CLKS signal selection kept after the port is no
longer in use the system might refuse to go suspend.
There is also a chance that the external clock is not running when next
time the McBSP port is started which can result errors when we try to
access McBSP registers.
Reset the CLKS source back to PRCM source unconditionally.

Subject: [PATCH 4884/6423] ASoC: omap McBSP: Clear rx_irq at probe time for
 OMAP4

On OMAP4 we have one interrupt line per McBSP port.
At probe time tx, and rx irq value will be -ENXIO,
and only the tx irq will get corrected.
In omap_mcbsp_request if the rx_irq is not 0 we proceed,
and try to request the interrupt, which will fail on
OMAP4 (rx_irq == -6).
To avoid this error, clear the rx_irq at probe time
on OMAP4.

Subject: [PATCH 4888/6423] ASoC: omap-mcbsp: Correct clock muxing for CLKR/FSR
 signals

Remove the no longer valid check for McBSP1 regarding to signal mux
selection (on OMAP4 McBSP4 has 6 pin setup).
Only clear the srgr2, pcr0 register configuration if the requested clock
configuration will actually going to touch it. In this way we can avoid
issues if the CLKR/FSR mux has been configured after the clock selection.

We are going to check for the valid McBSP port in the
omap_mcbsp_6pin_src_mux() function based on the validity of the mux_signal
callback (which is only valid for ports having 6 pin setup).

Subject: [PATCH 4889/6423] ASoC: omap-mcbsp: fix snd_pcm_hw_rule_add arguments

We are setting SNDRV_PCM_HW_PARAM_BUFFER_SIZE based on
SNDRV_PCM_HW_PARAM_CHANNELS, not vice versa. This bug didn't
have much impact because the rules are evaluated multiple times
by the core, and intended value got set eventually.

Subject: [PATCH 4893/6423] ALSA: hda - Rewrite the mute-LED hook with vmaster
 hook in patch_sigmatel.c

The mute-LED is controlled in patch_sigmatel.c by (ab-)using the
powersave hook.  This can be now rewritten with the vmaster hook
instead, which is much simpler and can work even without
CONFIG_SND_HDA_POWER_SAVE kconfig.

A drawback is that the mute-LED corresponds _only_ to the Master mixer
switch instead of checking the whole DACs.  But usually this shouldn't
be a big problem as PA enables the mixer elements accordingly.

Also, this patch changes the code to create vmaster always even on
STAC9200 and STAC925x.  The former "Master" on these chips are renamed
as "PCM" now.

Subject: [PATCH 4894/6423] ALSA: hda - Rewrite the mute-LED control with
 vmaster hook for ALC269

We've had ugly static handling of the mute-LED with a powersave hook
for ALC269 HP laptops just like done in patch_sigmatel.c.  This is now
rewritten with the new vmaster hook and a fixup code.

For that, the new fixup action, ALC_FIXUP_ACT_BUILD, is introduced.
It's called after build_controls is called.  The reason of this new
action is that vmaster hook must be added at this stage (not in init
or probe).

Subject: [PATCH 4895/6423] ALSA: hda - Add EAPD control to Conexnat
 auto-parser

Added the vmaster hook for controlling EAPD dynamically to Conexant
auto-parser.  When the Master is muted, EAPDs are turned off as well.
This will fix the missing mute-LED control on some machines in
addition to the more power-saving in the auto-parser mode.

Subject: [PATCH 4898/6423] xHCI: BESL calculation based on USB2.0 LPM errata

The latest released errata for USB2.0 ECN LPM adds new fields to USB2.0
extension descriptor, defines two BESL values for device: baseline BESL
and deep BESL. Baseline BESL value communicates a nominal power savings
design point and the deep BESL value communicates a significant power
savings design point.

If device indicates BESL value, driver will use a value count in both
host BESL and device BESL. Use baseline BESL value as default.

 shift

__ffs() can tell us which is the SEGMENT_SHIFT value
to be used. This will prevent problems when users are
too fast and don't pay attention to the need of fixing
the Shift after changing TRBS_PER_SEGMENT.

If we fail to locate a requested regulator return -EPROBE_DEFER. If drivers
pass this error code through to their caller (which they really should)
then this will ensure that the probe is retried later when further devices
become available.  In the unusual case where a driver doesn't want this
it can override the default behaviour.

Subject: [PATCH 4906/6423] ASoC: wm8994: Prevent ABBA deadlock with CODEC and
 accdet mutexes

Currently we can the accdet mutex from within DAPM when updating the device
state which means we take accdet then the CODEC mutex but we also do the
locking the other way around when responding to the jackdet IRQ. Move all
the jackdet use of the CODEC mutex out of the accdet lock to avoid this.
Since all the DAPM interactions depend only on a single threaded IRQ this
is still serialised.

The locking improvements in 3.5 allow a better solution there.

Subject: [PATCH 4909/6423] mac80211: Limit TID buffering during BA session
 setup/teardown

While setting up or tearing down a BA session mac80211 is buffering
pending frames for the according TID. However, there's currently no
limit on how many frames are buffered possibly leading to an out-of-
memory situation. This can happen on systems with little memory when
the CPU is fully loaded since the BA session work is executed in
process context while frames can still come via softirq.

Apply a limitation to the TIDs pending queue to avoid consuming
too much memory in this situation.

ipw2200 driver does not use these defines, it uses geo struct instead.
Therefore remove them from its header.

Note: we keep them in the ipw2100 driver's header, because the driver
still uses them.

Subject: [PATCH 4914/6423] mac80211: remove tx_sync

When the station state callback was added, this
was no longer needed in theory. With the iwlwifi
changes to remove use of it landing, we can kill
the entire tx-sync framework again, RIP.

Subject: [PATCH 4915/6423] mac80211: set channel back after disassociating

As we've discussed, we want to avoid channel changes
while associated. While the part when we actually
associate needs a bit more work, the bit that happens
on disassociating can be changed quite easily. Move
the channel type change later in the disassociate
process to set the channel only after the driver was
told that it's now disassociated.

As the driver could expect powersave to be enabled
only when associated, this thus results in splitting
the config call, but overall what happens makes more
sense this way.

Disable multi stream rates (MCS > 7) when a STA is in static SMPS mode
since it has only one active rx chain. Hence, it doesn't even make

Subject: [PATCH 4917/6423] rt2x00: Fix beacon skew in rt2800pci

rt2800pci is suffering from beacon skew in AP mode. Some powersaving
clients (like VOIP phones) are getting into trouble after some time
when the beacon skew is getting too big.

The ralink legacy drivers contain a function that indicates that the
beacon timer is off by 1us per tbtt. And this function works around
that by reducing the beacon interval for every 64th beacon transmission
by 64us (the smallest possible value). Do the same in rt2800pci.

This allows proper powersaving when rt2800pci is used in AP mode.

 workaround

Mohammed Shafi ran into [1] the SEQ_RX_FRAME workaround
warning with a statistics notification, this means we
can't just remove it as we'd hoped.

Abstract it out so that the higher layer can configure
this as a kind of "filter" in the transport.

Subject: [PATCH 4925/6423] iwlwifi: move wait_command_queue from shared to
 trans

This wait queue really belongs to the transport
layer, as it is used for sending synchronous
commands to the HW.

However, only op_mode knows about errors and
exceptional conditions, so make this queue
accessible by the op_mode.

Subject: [PATCH 4927/6423] iwlwifi: explicitly track whether INIT uCode was
 run

Remove IWL_UCODE_NONE from enum iwl_ucode_type which,
by being the default value in 0-initialized memory,
implicitly allowed us to track whether any uCode had
ever been loaded successfully (which would have been
the INIT uCode) and instead explicitly track whether
or not INIT uCode has been run.

From 0cedacc5797bbae5b07e5e861fbe7b8e33f2ef78 Mon Sep 17 00:00:00 2001
From: David Spinadel <david.spinadel@intel.com>
Date: Sat, 10 Mar 2012 13:00:12 -0800
Subject: [PATCH 4928/6423] iwlwifi: more modularity in fw images and sections

Changed iwl_firmware_pieces structure to support an array of
separate images, and an array of sections for each image.

In fw_sec and fw_desc structures, added a field for
offset from the HW address, to support 16.0 uCode that
provides an offset instead of any other data about the section.
This field is filled with default values when parsing instruction
or data section.

Subject: [PATCH 4930/6423] iwlwifi: change struct iwl_fw

Change iwl_fw struct to hold an array of fw_img instead of
three separated instances.

Change fw_img to hold an array of fw_desc instead of two
separate descriptors for instructions and data.

Change load_given_ucode, load_section, verification functions
etc. to support this structure.

Subject: [PATCH 4934/6423] mac80211: simplify wmm check during association

Instead of setting assoc_data->wmm_used solely
based on the BSS also take into account our own
capabilities and later check those.

Also rename "wmm_used" and "uapsd_used" to just
"wmm" and "uapsd".

Subject: [PATCH 4936/6423] mac80211: refactor common auth/assoc setup code

As associating is possible without first authenticating
(for FT over DS) association also has to be able to
switch to the right channel, insert the station entry
etc. Factor out this common code into a new function
called ieee80211_prep_connection().

Subject: [PATCH 4937/6423] mac80211: set basic rates earlier

The authentication and association handshake
already happens in the context of the new BSS,
and the basic rates are needed at least for
the ACK response frame to the authentication
or association response frames. Therefore the
basic rates should already be configured into
the driver when those frames are sent.

Change the logic to set up the basic rates in
the connection preparation that happens for
authentication and association (if needed).

Subject: [PATCH 4942/6423] fbdev: sh_mobile_lcdc: Move pm runtime enable to
 probe()

The pm_runtime_enable() and pm_runtime_resume() calls don't belong to
sh_mobile_lcdc_setup_clocks(). Move them to the probe function. Remove
the unneeded pm_runtime_resume() call.

Subject: [PATCH 4945/6423] fbdev: sh_mobile_hdmi: Don't access LCDC channel in
 notifier callback

Instead of relying on info->par being a pointer to an LCDC channel, cast
the notifier block pointer to an sh_hdmi pointer.

Subject: [PATCH 4950/6423] fbdev: sh_mobile_lcdc: Handle HDMI/MIPI transmitter
 device directly

Pass a pointer to the transmitter device through platform data, retrieve
the corresponding sh_mobile_lcdc_entity structure in the probe method
and call the transmitter display_on/off methods directly.

Subject: [PATCH 4964/6423] sh_mobile_lcdc: Add display notify callback to
 sh_mobile_lcdc_chan

The callback implements 3 notification events:

- SH_MOBILE_LCDC_EVENT_DISPLAY_CONNECT notifies the LCDC that the
  display has been connected
- SH_MOBILE_LCDC_EVENT_DISPLAY_DISCONNECT notifies the LCDC that the
  display has been disconnected
- SH_MOBILE_LCDC_EVENT_DISPLAY_MODE notifies that LCDC that a display
  mode has been detected

Subject: [PATCH 4967/6423] fbdev: sh_mobile_hdmi: Don't set sh_hdmi::mode in
 the display on handler

The struct sh_hdmi mode field is only used after being assigned by the
EDID read code. There is thus no need to initialize it from the LCDC
display var in the display on handler.

Subject: [PATCH 4968/6423] fbdev: sh_mobile_hdmi: Don't access LCDC fb_info

The LCDC fb_info structure is only used to retrieve the default video
mode in case none of the modes advertised by EDID information is
acceptable. Pass a pointer to the default mode through the
sh_mobile_lcdc_entity structure instead.

From 93ff259846a774ff37dca54792c5a3a6425882c0 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Tue, 29 Nov 2011 14:33:41 +0100
Subject: [PATCH 4970/6423] fbdev: sh_mobile_lcdc: Rename (lcd|num)_cfg
 (lcd|num)_modes

The struct sh_mobile_lcdc_chan_cfg platform data contains a list of
video modes. Name the lcd_cfg and num_cfg fields to reflect that they
describe video modes.

Subject: [PATCH 4972/6423] fbdev: sh_mobile_lcdc: Add sh_mobile_format_info()
 function

The function returns a pointer to a structure describing a format based
on its fourcc. Use the function where applicable instead of hardcoded
switch-case statements.

Subject: [PATCH 4973/6423] fbdev: sh_mobile_lcdc: Store the format in struct
 sh_mobile_lcdc_chan

Store the active format in the channel structure, and use it instead of
parsing info->var all over the place when the format is needed.

Subject: [PATCH 4977/6423] fbdev: sh_mobile_lcdc: Pass channel pointer to
 sh_mobile_wait_for_vsync

The sh_mobile_wait_for_vsync() function isn't related to the fbdev API,
make it generic by passing a channel pointer instead of an fb_info
pointer.

MERAM space. Only the register space needs to be ioremapped, split the
resource to make that possible.

From 2a618e0333f5d1d27bbd4d90d70f07e0a8dc0ba7 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Mon, 19 Sep 2011 11:40:31 +0200
Subject: [PATCH 4983/6423] fbdev: sh_mobile_meram: Add struct
 sh_mobile_meram_icb

The new structure stores ICB parameters for ICBs.

Instead of modifying the struct sh_mobile_meram_cfg instances passed by
callers, store the ICB parameters internally and make the public API
take const pointers to sh_mobile_meram_cfg.

From 481100506b34d666243832c3f2aee905c03cb8e7 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Mon, 12 Dec 2011 16:36:13 +0100
Subject: [PATCH 4987/6423] fbdev: sh_mobile_meram: Allocate ICBs automatically

Instead of manually specifying the ICBs to use in platform data,
allocate them automatically at runtime. The range of reserved ICBs (for
instance to be used through UIO), if any, is passed in the platform data
reserved_icbs field as a bitmask.

The MERAM registration function now returns a pointer to an opaque MERAM
object, which is passed to the update and unregistration functions.

Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

From b0a49d98fa4315c17a098cb60ccc626645ed9756 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Sun, 11 Sep 2011 23:30:45 +0200
Subject: [PATCH 4988/6423] arm: mach-shmobile: Don't set MERAM ICB numbers in
 platform data

The marker and cache ICBs are now allocated automatically, there's no
need to specify them manually anymore.

Subject: [PATCH 4990/6423] fbdev: sh_mobile_lcdc: Don't store copy of platform
 data

Instead of copying the whole platform data structure to struct
sh_mobile_lcdc_chan, store a const pointer to the channel platform data.

MERAM configuration information needs to be changed at runtime, so copy
it to struct sh_mobile_lcdc_chan.

Subject: [PATCH 4993/6423] fbdev: sh_mobile_meram: Remove unneeded sanity
 checks

The meram_register(), meram_unregister() and meram_update() operations
check that the pointers they get from the caller are not NULL. Those
checks can be remove, as the caller already ensures that the pointers
are valid.

The platform sanity checks can also be removed, as the operations can't
be accessed without valid platform data anyway.

Subject: [PATCH 4995/6423] pinctrl: allow concurrent gpio and mux function
 ownership of pins

Per recent updates to Documentation/gpio.txt, gpiolib drivers should
inform pinctrl when a GPIO is requested. pinctrl then marks that pin as
in-use for that GPIO function.

When an SoC muxes pins in a group, it's quite possible for the group to
contain e.g. 6 pins, but only 4 of them actually be needed by the HW
module that's mux'd to them. In this case, the other 2 pins could be
used as GPIOs. However, pinctrl marks all the pins within the group as
in-use by the selected mux function. To allow the expected gpiolib
interaction, separate the concepts of pin ownership into two parts: One
for the mux function and one for GPIO usage. Finally, allow those two
ownerships to exist in parallel.

< 0 comparison was not true, letting errors pass through,
ending up as mapped to pin "-22". Fix this up and print
the error.

Subject: [PATCH 4997/6423] pinctrl: introduce generic pin config

This is a split-off from the earlier patch set which adds generic
pin configuration for the pin controllers that want it. Since
we may have a system with mixed generic and custom pin controllers,
we pass a boolean in the pin controller ops vtable to indicate
if it is generic.

ChangeLog v1->v5:
- Follow parent patch versioning number system.
- Document the semantic meaning of return values from pin config
  get functions, so we can iterate over pins and check their
  properties from debugfs as part of the generic config code.
- Use proper cast functions in the generic debugfs pin config
  file.
- Expand generic config to optionally cover groups too.
ChangeLog v5->v6:
- Update to match underlying changes.
ChangeLog v6->v7:
- Drop DRIVE_OFF parameter, use bias high impedance for this
- Delete argument for drive modes push-pull, od and os. These
  are now just state transitions.
- Delete slew rate rising/falling due to discussions on on
  proper semantics
- Drop config wakeup, struct irq_chip does this for now, add
  back if need be.
- Set PIN_CONFIG_END to 0x7fff making room for custom config
  parameters from 0x8000 and up.
- Prefix accessor functions with pinconf_

+ * @PIN_CONFIG_DRIVE_OPEN_DRAIN: the pin will be driven with open drain (open

+ *	which are then pulled up with an external resistor. Sending this
+ *	config will enabale open drain mode, the argument is ignored.

+ *	argument is ignored.
+ * @PIN_CONFIG_INPUT_SCHMITT: this will configure an input pin to run in

+ *	setting pins to this mode. The argument zero turns the schmitt trigger
+ *	off.
+ * @PIN_CONFIG_INPUT_DEBOUNCE: this will configure the pin to debounce mode,
+ *	which means it will wait for signals to settle when reading inputs. The
+ *	argument gives the debounce time on a custom format. Setting the
+ *	argument to zero turns debouncing off.
+ * @PIN_CONFIG_POWER_SOURCE: if the pin can select between different power
+ *	supplies, the argument to this parameter (on a custom format) tells
+ *	the driver which alternative power source to use.
+ * @PIN_CONFIG_LOW_POWER_MODE: this will configure the pin for low power
+ *	operation, if several modes of operation are supported these can be
+ *	passed in the argument on a custom form, else just use argument 1
+ *	to indicate low power mode, argument 0 turns low power mode off.

From a050b3eee61666421df786c8d898ec22c129f4af Mon Sep 17 00:00:00 2001
From: Linus Walleij <linus.walleij@linaro.org>
Date: Wed, 16 Nov 2011 20:10:09 +0100
Subject: [PATCH 4998/6423] pinctrl/coh901: use generic pinconf enums and
 parameters

Adjust the COH 901 driver to use the standard enums for
biasing and driving pins, alter signature of config function
to suit the framework.

From: Linus Walleij <linus.walleij@linaro.org>
Date: Wed, 16 Nov 2011 21:58:10 +0100
Subject: [PATCH 4999/6423] pinctrl: support pinconfig on the U300

This adds pin configuration support for the U300 driver pair,
we can now read out the biasing and drive mode in debugfs and
configure it using the new configuration API.

ChangeLog v1->v2:
- Migrate to pin config and generic pin config changes.
ChangeLog v2->v3:
- Adjust to generic pin config changes in v7 patch set.

Subject: [PATCH 5000/6423] ARM: u300: configure some pins as an example

To show how the pin configuration is used on the U300, let's
include some configs for two GPIO pins.

ChangeLog v1->v2:
- Provide a better example, set the clock return pin to pull-up
  and set the card detect pin to high impedance.

Subject: [PATCH 5004/6423] IB/mlx4: Fix possible missed completion event

If an erroneous CQE is polled in the first iteration (i.e. npolled ==
0), we don't update the consumer index and hence the hardware could
get a wrong notion of how many CQEs software polled.  Fix this by
unconditionally updating the doorbell record.  We could change the
check to be something like

	if (npolled || err != -EAGAIN)
		...

but it does not seem worth the effort since a posted write to memory
should not cost too much.

Subject: [PATCH 5005/6423] IB/mlx4: Fix info returned when querying IBoE ports

To issue a port query, use the QUERY_(Ethernet)_PORT command instead
of the MAD_IFC command, since MAD_IFC attempts to query the firmware
IB SMA, which is irrelevant for IBoE ports.

This allows us to handle both 10Gb/s and 40Gb/s rates (e.g in sysfs),
using QDR speed (10Gb/s) and width of 1X or 4X.

Subject: [PATCH 5006/6423] mlx4_core: Allow dynamic MTU configuration for IB
 ports

Set the MTU for IB ports in the driver instead of using the firmware
default of 2KB (the driver defaults to 4KB).  Allow for dynamic mtu
configuration through a new, per-port sysfs entry.

Since there's a dependency between the port MTU and the max number of
HW VLs the port can support, apply a mim/max approach, using a loop
that goes down from the highest possible number of VLs to the lowest,
using the firmware return status to know whether the requested number
of VLs is possible with a given MTU.

For now, as with the dynamic link type change / VPI support, the sysfs
entry to change the mtu is exposed only when NOT running in SR-IOV
mode.  To allow changing the MTU for the master in SR-IOV mode,
primary-function-initiated FLR (Function Level Reset) needs to be
implemented.

Subject: [PATCH 5007/6423] mlx4_core: Scale size of MTT table with system RAM

The current driver defaults to 1M MTT segments, where each segment holds
8 MTT entries.  This limits the total memory registered to 8M * PAGE_SIZE
which is 32GB with 4K pages.  Since systems that have much more memory
are pretty common now (at least among systems with InfiniBand hardware),
this limit ends up getting hit in practice quite a bit.

Handle this by having the driver allocate at least enough MTT entries to
cover 2 * totalram pages.

From 3b72fca09d7aed0c1a390370eb3f3f4f0480702a Mon Sep 17 00:00:00 2001
From: Andiry Xu <andiry.xu@amd.com>
Date: Mon, 5 Mar 2012 17:49:32 +0800
Subject: [PATCH 5008/6423] xHCI: store ring's type

When allocate a ring, store its type - four transfer types for endpoint,
TYPE_STREAM for stream transfer, and TYPE_COMMAND/TYPE_EVENT for xHCI host.

This helps to get rid of three bool function parameters: link_trbs, isoc
and consumer.

From afd465030acb4098abcb6b965a5aebc7ea2209e0 Mon Sep 17 00:00:00 2001
From: Joe Perches <joe@perches.com>
Date: Mon, 12 Mar 2012 07:03:32 +0000
Subject: [PATCH 5009/6423] net: ipv4: Standardize prefixes for message logging

Add #define pr_fmt(fmt) as appropriate.

Add "IPv4: ", "TCP: ", and "IPsec: " to appropriate files.
Standardize on "UDPLite: " for appropriate uses.
Some prefixes were previously "UDPLITE: " and "UDP-Lite: ".

Add KBUILD_MODNAME ": " to icmp and gre.
Remove embedded prefixes as appropriate.

Add missing "\n" to pr_info in gre.c.

Subject: [PATCH 5010/6423] net/hyperv: Fix data corruption in
 rndis_filter_receive()

Limiting the memcpy to be the sizeof(struct rndis_message) can truncate
the message if there are Per-Packet-Info or Out-of-Band data.

In my earlier patch (commit 45326342), the unnecessary kmap_atomic and
kunmap_atomic surrounding this memcpy have been removed because the memory
in the receive buffer is always mapped. This memcpy is not necessary
either. To fix the bug, I removed the memcpy.

Previously, we used a hard-coded value as paramater, instead of using the
input's value. This is now remedied, as in other flows.

Recent commit 4ca40c2ce099e4f1ce3 (md/raid10: Allow replacement device ...)
added an smp_mb in end_sync_write.
This was to close a possible race with raid10_remove_disk.
However there is no such race as it is never attempted to remove a
disk while resync (or recovery) is happening.
so the smp_mb is just noise.

Subject: [PATCH 5026/6423] igb: fix ethtool offline test

A bug was introduced with the following patch:

  Commmit bdbc063129e811264cd6c311d8c2d9b95de01231
  Author: Eric Dumazet <eric.dumazet@gmail.com>
  igb: Add support for byte queue limits.

The ethtool offline tests will cause a perpetual link flap, this
is because the tests also need to account for byte queue limits (BQL).

Subject: [PATCH 5027/6423] ixgbe: remove tie between NAPI work limits and
 interrupt moderation

As noted by Ben Hutchings and David Miller, work limits for NAPI
should not be tied to interrupt moderation parameters.  This
should be handled by NAPI, possibly through sysfs.

Neil Horman & Stephen Hemminger are working on a solution for
NAPI currently.  In the meantime, remove this tie between
work limits and interrupt moderation.

Subject: [PATCH 5029/6423] net: Fix issue with netdev_tx_reset_queue not
 resetting queue from XOFF state

We are seeing dev_watchdog hangs on several drivers.  I suspect this is due
to the __QUEUE_STATE_STACK_XOFF bit being set prior to a reset for link
change, and then not being cleared by netdev_tx_reset_queue.  This change
corrects that.

In addition we were seeing dev_watchdog hangs on igb after running the
ethtool tests.  We found this to be due to the fact that the ethtool test
runs the same logic as ndo_start_xmit, but we were never clearing the XOFF
flag since the loopback test in ethtool does not do byte queue accounting.

Subject: [PATCH 5031/6423] ixgbe: Do no clear Tx status bits since eop_desc
 provides enough info

There isn't any need to clear the status bits in the descriptors due to the
fact that the eop_desc provides enough information for us to know
that we have cleaned to the last packet that the software has put on the
ring.  The status bits are cleared as a part of putting the frame on the
ring so as long as we do not read the descriptor bit prior to reading the
value eop_desc we should be able to guarantee that we will not clean beyond
the end of the current data stream.

Subject: [PATCH 5033/6423] ixgbe: Address issues with Tx WHTRESH value not
 being set correctly

This change is meant to address the fact that the tx_itr_setting was
dropping to 0 when no separate Tx vectors were provided.  This had resulted
in the driver incorrectly configuring the Tx ring with a WTHRESH of 1 in
order to avoid Tx hangs even though that was not necessary. This change
makes it so that we instead take a look at the Tx ring's q_vector to
determine if the ring will have an ITR value less than 8us.

The old code had several errors in how it was determining the vector

will attempt to always allocated paired Rx/Tx vectors instead of attempting
to allocate individual vectors when the number of queues is less than the
number of CPUs.

Subject: [PATCH 5037/6423] ixgbe: Allocate rings as part of the q_vector

This patch makes the rings a part of the q_vector directly instead of
indirectly.  Specifically on x86 systems this helps to avoid any cache
set conflicts between the q_vector, the tx_rings, and the rx_rings as the
critical stride is 4K and in order to cross that boundary you would need to
have over 15 rings on a single q_vector.

In addition this allows for smarter allocations when Flow Director is
enabled.  Previously Flow Director would set the irq_affinity hints based
on the CPU and was still using a node interleaving approach which on some
systems would end up with the two values mismatched.  With the new approach
we can set the affinity for the irq_vector and use the CPU for that
affinity to determine the node value for the node and the rings.

From a557928e26b08496c8f4b6c04e3838ad8048ad85 Mon Sep 17 00:00:00 2001
From: Alexander Duyck <alexander.h.duyck@intel.com>
Date: Wed, 8 Feb 2012 07:50:04 +0000
Subject: [PATCH 5038/6423] ixgbe: Add iterator for cycling through rings on a
 q_vector

Since there are multiple spots where we have to cycle through all of the
rings on a q_vector it makes sense to just add a function for iterating
through all of them.

Subject: [PATCH 5039/6423] ixgbe: Simplify logic for ethtool loopback frame
 creation and testing

This change makes it a bit easier to do the loopback frame creating and
testing.  Previously we were doing an and to drop the last bit, and then
dividing the frame_size by 2 in order to get locations for frame bytes and
testing.  Instead we can simplify it by just shifting the register one bit
to the right and using that for the frame offsets.

This change also replaces all instances of rx_buffer_info with just
rx_buffer since that is closer to the name of the actual structure being
used and can save a few extra characters.

In addition I have updated the logic for cleaning up a test frame so that
we pass an rx_buffer instead of the sk_buff.  The main motivation behind
this is changes that will replace the sk_buff with just a page in the
future.

Subject: [PATCH 5040/6423] x86/ioapic: Add register level checks to detect
 bogus io-apic entries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With the recent changes to clear_IO_APIC_pin() which tries to
clear remoteIRR bit explicitly, some of the users started to see
"Unable to reset IRR for apic .." messages.

Close look shows that these are related to bogus IO-APIC entries
which return's all 1's for their io-apic registers. And the
above mentioned error messages are benign. But kernel should
have ignored such io-apic's in the first place.

Check if register 0, 1, 2 of the listed io-apic are all 1's and
ignore such io-apic.

This calculation determines the physical dimensions of the tablet,

resolution.

Instead of dividing the logical size by the resolution, the current
code performs a multiplication. This doesn't pose a problem for the
3rd-gen Bamboo since the resolution and scale factor happen to be
identical, but will produce an incorrect result for other cases.

From f29735cbef4eb6072e5ae459b556f3a061efc47e Mon Sep 17 00:00:00 2001
From: Takashi Iwai <tiwai@suse.de>
Date: Tue, 13 Mar 2012 07:55:10 +0100
Subject: [PATCH 5045/6423] ALSA: hda - Add expose_enum_ctl flag to
 snd_hda_add_vmaster_hook()

Since it's not always safe to assume that the vmaster hook is purely the
mute-LED control, add the flag indicating whether to expose the mute-LED
enum control or not.  Currently, conexant codec sets this off for non-HP
laptops where EAPD may be used really as EAPD.

Subject: [PATCH 5048/6423] drm/nv20: split PFB code out of nv10_fb.c

Most functions were quite different between NV10/NV20 already, and they're
about to get even more so.

Subject: [PATCH 5049/6423] drm/nv20-nv40: add memory type detection

NV20/NV30 is partially educated guesswork at this point, based on any
information around about available memory types and a horribly unspeakable
amount of vbios image scouring.  I'm not entirely certain the GDDR3 define
is correct, I have not spotted a single vbios with that value yet (though
it is mentioned in some 1218-using nv4x vbios), but there are reports that
some nv3x did use it..

NV40(100914) confirmed by switching an NV49 to DDR1/DDR2 values and making
sure that the binary driver behaviour showed it had detected DDR1/DDR2
instead of GDDR3 before dying horribly.

NV40(100474) confirmed by doing much the same task as above on an NV44,
except this was *much* easier as changing the values didn't seem to have
any noticable effect on the memory controller aside from changing the
binary driver's behaviour.

Subject: [PATCH 5050/6423] drm/nv50: add memory type detection

DDR1/DDR[23] confirmed on NVA8 (see note about DDR3 in source) by changing
the value and watching the binary driver's behaviour.

GDDR3/4 values confirmed on a NV96 via the same method above.  That GDDR4
is present is interesting, as far as I can see no boards using it were ever
released.

GDDR5 value is based on VBIOS images of known GDDR5 boards.

Subject: [PATCH 5051/6423] drm/nv50: hopefully handle the DDR2/DDR3 memtype
 detection somewhat better

M version 2 appears to have a table with some form of memory type info
available.

NVIDIA appear to ignore the table information except for this DDR2/DDR3
case (which has the same value in 0x100714).  My guess is this is due to
some of the supported memory types not being represented in the table.

Uses only the VBIOS tables, from what I can tell this is what NVIDIA do
too, I was able to change the detected memory type by modifying this table
on a NVC1 chipset.

From bfb314652430ceca302bae0981d00903f055eee4 Mon Sep 17 00:00:00 2001
From: Roy Spliet <r.spliet@student.tudelft.nl>
Date: Fri, 25 Nov 2011 15:52:22 +0100
Subject: [PATCH 5058/6423] drm/nouveau/pm: improve memory timing generation

- Rename several VBIOS entries to closer match the real world
- Add the missing 0x100238 and 0x100240 register values
- Parse bit 14 of the VBIOS timing table
- "Magic value" -> tCWL, fixing some minor bugs in the process
- Also name a few more by their name rather than their number.
- Some values seem to be dependent on the memory type. Fix

Edits by Martin Peres <martin.peres@labri.fr>:
- this is a squash commit
- reworked for fixing some style issues

Subject: [PATCH 5061/6423] drm/nouveau/pm: restructure bios table parsing

It turns out we need access to some additional information in various VBIOS
tables to handle PFB memory timings correctly.

Rather than hack in parsing of the new stuff in some kludgy way, I've
restructured the VBIOS parsing to be more primitive, so we can use them in
more flexible ways in the future.

The perflvl->timing association code is disabled for the moment until it can
be reworked.  We don't use this stuff yet anyway, so no harm done.

From c7c039fd31be82ecb8d48477955e76badd38141a Mon Sep 17 00:00:00 2001
From: Roy Spliet <r.spliet@student.tudelft.nl>
Date: Mon, 9 Jan 2012 15:23:07 +1000
Subject: [PATCH 5062/6423] drm/nouveau/pm: implement DDR2/DDR3/GDDR3/GDDR5 MR
 generation and validation

Roy Spliet:
- Implement according to specs
- Simplify
- Make array for mc latency registers

Martin Peres:
- squash and split all the commits from Roy
- rework following Ben Skeggs comments
- add a form of timings validation
- store the initial timings for later use

Ben Skeggs
- merge slightly modified tidy-up patch with this one
- remove perflvl-dropping logic for the moment

From fd99fd6100d3b7aaa8dc76888a38bbb15e8041bc Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Tue, 17 Jan 2012 21:10:58 +1000
Subject: [PATCH 5064/6423] drm/nouveau/pm: calculate memory timings at perflvl
 creation time

Statically generating the PFB register and MR values for each timing set
turns out to be insufficient.  There's at least one (so far) known piece
of information which effects MR values which is stored in the perflvl
entry on some chipsets (and in another table on later ones), which is
disconnected from the timing table entries.

After this change we will generate a timing set based on an input clock
frequency instead, and have this data stored in the performance level
data.

Subject: [PATCH 5066/6423] drm/nouveau/pm: introduce ram reclocking helper

This will probably result in more lines of code, however, we're going to
have at least 3 slightly different implementations of this very soon and
I'd rather keep the ram reclocking logic separate from the hw specifics.

DDR2/DDR3/GDDR3 implemented thus far, others will be added as necessary.

There's some "extended" GDDR3 chipsets out there with EMRS2 settings that
change the layout of MRS/EMRS1 bitmaps.. Sigh.. Still need to track down
how exactly we're supposed to handle this.

Subject: [PATCH 5085/6423] drm/nouveau/mxm: call mxmi to determine revision
 before calling mxms

There's a HP laptop out there where the MXM version in the VBIOS doesn't
match what the ACPI implementation is expecting.  These tables will accept
0x00 to MXMS to return latest version, but *only* if MXMI has been called
first..

There's also a workaround for reading the PROM VBIOS on some chipsets.

Subject: [PATCH 5097/6423] drm/nv50/hwsq: some nv92 fixes

The shift from hwsq_data = 0x1400 to 0x080000 actually happened in nv94, not nv92
This fixes some reclocking issues on my newly acquired nv92

Subject: [PATCH 5102/6423] drm/nvd0/disp: move syncs/magic setup to or
 mode_set

NVIDIA appear to do these around the same place they do the MODE_CTRL
methods, and for DP at least we need to bash some extra bits in "syncs"
to keep EVO happy.

It's a bit of a guess as to the 6/8bpc, but i have no better idea yet.

Subject: [PATCH 5107/6423] ath6kl: fix regression in
 ath6kl_upload_board_file()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

My patch 24fc32b3 ("ath6kl: add ath6kl_bmi_write_hi32()") caused a regression
in ath6kl_upload_board_file() and the board_address variable was not
properly initialised in some cases:

ath6kl/init.c:1068:6: warning: ‘board_address’ may be used uninitialized
in this function

Most likely this broke ar6004 support but I can't test that right now.

Subject: [PATCH 5112/6423] OMAPDSS: APPLY: fix clearing shadow dirty flag with
 manual update

Currently the shadow-dirty flags for manual update displays is cleared
in the apply_irq_handler when an update has finished. This is not
correct, as the shadow registers are taken into use (i.e. after that
they are not dirty) when the update is started.

Move the mgr_clear_shadow_dirty() call from apply_irq_handler to
dss_mgr_start_update() to fix this.

the bottom (high address) of the stack and pcpu_devices->panic_stack
points to the top (low address). We now pass the bottom of the stack
which is pcpu_devices->panic_stack + PAGE_SIZE.

In the past, the room_on_ring() check was implemented by walking all over

Count the number of free TRBs instead. The free TRBs number should be
updated when enqueue/dequeue pointer is updated, or upon the completion
of a set dequeue pointer command.

Subject: [PATCH 5117/6423] xHCI: set cycle state when allocate rings

In the past all the rings were allocated with cycle state equal to 1.
Now the driver may expand an existing ring, and the new segments shall be
allocated with the same cycle state as the old one.

This affects ring allocation and cached ring re-initialization.

Subject: [PATCH 5118/6423] xHCI: dynamic ring expansion

If room_on_ring() check fails, try to expand the ring and check again.

When expand a ring, use a cached ring or allocate new segments, link
the original ring and the new ring or segments, update the original ring's
segment numbers and the last segment pointer.

Subject: [PATCH 5127/6423] ALSA: hda - fix printing of high HDMI sample rates

A previous commit af65cbf296 (ALSA: hdmi: fix printout of SAD sampling
rates) fixed the sample rates shown in /proc/asound/cardX/eldY and
kernel log to not be entirely wrong. However, a missing rate from the
array added in the patch causes HDMI rates 88.2 kHz, 96 kHz, 176.4 kHz,
and 192 kHz to be shown as 96 kHz, 176.4 kHz, 192 kHz, and 384 kHz,
respectively.

Fix the reporting by adding the ALSA rate 64 kHz into the conversion
array between 48 kHz and 88.2 kHz.

Subject: [PATCH 5129/6423] xenbus: don't free other end details too early

The individual drivers' remove functions could legitimately attempt to
access this information (for logging messages if nothing else). Note
that I did not in fact observe a problem anywhere, but I came across
this while looking into the reasons for what turned out to need the
fix at https://lkml.org/lkml/2012/3/5/336 to vsprintf().

Subject: [PATCH 5130/6423] b43legacy: Load firmware from work queue instead of
 from probe routine

Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43legacy has such a structure, it must be changed.
As this driver loads 3 or 4 firmware files, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a work queue that calls the firmware loading routines.

Subject: [PATCH 5131/6423] b43: Load firmware from a work queue and not from
 the probe routine

Recent changes in udev are causing problems for drivers that load firmware
from the probe routine. As b43 has such a structure, it must be changed.
As this driver loads more than 1 firmware file, changing to the asynchronous routine
request_firmware_nowait() would be complicated. In this implementation, the probe
routine starts a queue that calls the firmware loading routines.

This is better done inside the WEP decrypt
function where it doesn't have to check all
the conditions any more since they've been
tested already.

Subject: [PATCH 5133/6423] mac80211: linearize SKBs as needed for crypto

Not linearizing every SKB will help actually pass
non-linear SKBs all the way up when on an encrypted
connection. For now, linearize TKIP completely as
it is lower performance and I don't quite grok all
the details.

Subject: [PATCH 5136/6423] mwifiex: merge functions to derive cfp by chan &
 freq in one

There exist different functions with very long names
to derive the channel frequency and power tripplet
based on band and channel/freq.

Subject: [PATCH 5137/6423] mwifiex: use usleep_range instead of udelay

For the delay of 10 uSec or more usleep_range is prefered.
Unlike udelay, sleep_range avoids large number of undesired
interrupts.

Subject: [PATCH 5143/6423] mac80211: rename bss_conf timestamp to last_tsf

This value is not really very useful by itself,
yet some drivers (including iwlwifi until I can
figure out what it should do) use it. At least
rename it to "last_tsf" to indicate the meaning
and add a note that it may be really old.

I suspect the value may become useful combined
with the rx_status->mactime, but we don't (yet)
store that value and pass it to the driver.

Subject: [PATCH 5144/6423] mac80211: Don't let regulatory make us deaf

When regulatory information changes our HT behavior (e.g,
when we get a country code from the AP we have just associated
with), we should use this information to change the power with
which we transmit, and what channels we transmit.  Sometimes
the channel parameters we derive from regulatory information
contradicts the parameters we used in association.  For example,
we could have associated specifying HT40, but the regulatory
rules we apply may forbid HT40 operation.

In the situation above, we should reconfigure ourselves to
transmit in HT20 only, however it makes no sense for us to
disable receive in HT40, since if we associated with these
parameters, the AP has every reason to expect we can and
will receive packets this way.  The code in mac80211 does
not have the capability of sending the appropriate action
frames to signal a change in HT behaviour so the AP has
no clue we can no longer receive frames encoded this way.
In some broken AP implementations, this can leave us
effectively deaf if the AP never retries in lower HT rates.

This change breaks up the channel_type parameter in the
ieee80211_enable_ht function into a separate receive and
transmit part.  It honors the channel flags set by regulatory
in order to configure the rate control algorithm, but uses
the capability flags to configure the channel on the radio,
since these were used in association to set the AP's transmit
rate.

Subject: [PATCH 5145/6423] NFS: null dereference in dev_remove()

In commit 5ffaf85541 "NFS: replace global bl_wq with per-net one" we
made "msg" a pointer instead of a struct stored in stack memory.  But we
forgot to change the memset() here so we're still clearing stack memory
instead clearing the struct like we intended.  It will lead to a kernel
crash.

Subject: [PATCH 5146/6423] ahci: add AHCI_HFLAG_DELAY_ENGINE host flag

The following commit was intended to fix problems with specific AHCI
controller(s) that would become bricks if the AHCI specification was not
followed strictly (that is, if ahci_start_engine() was called while the
controller was in the wrong state):

    commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7
    ahci: start engine only during soft/hard resets

However, some devices currently have issues with that fix, so we must
implement a flag that delays the ahci_start_engine() call only for specific
controllers.

This commit simply introduces the flag, without enabling it in any driver.

Note that even when AHCI_HFLAG_DELAY_ENGINE is not enabled, this patch does
not constitue a full revert to commit 7faa33da; there is still a change in
behavior to the ahci_port_suspend() failure path.

Subject: [PATCH 5149/6423] drivers/ata/pata_mpc52xx.c: clean up error handling
 code

This patch makes a number of changes with respect to the error-handling
code:

* Remove cleanup calls for the devm functions in both the error handling
  code and the remove function.  This cleanup is done automatically.

* The previous change simplifies the cleanup code at the end of the
  function such that there is nothing to do on the failure of the call to
  devm_ioremap.  So it is changed to just return directly.

* There is no need for the ifs in the cleanup code at the end of the
  function, because in each case the cleanup needed is statically
  known.  Drop the ifs, add new err labels, and drop the initializations of
  the tested variables to NULL.

* Change the call to request_irq to a call to devm_request_irq, so that it
  is cleaned up on exit.

* Cause the return value of devm_request_irq to go into the returned
  variable rv rather than the unused variable ret.  Drop ret.

Subject: [PATCH 5151/6423] pata_cmd64x: use interrupt status from MRDMODE
 register

Start using faster version of the bmdma_stop() method for the PCI0646U and newer
chips that have the duplicate interrupt status  bits  in  the I/O mapped MRDMODE
register. Use the old, slow bmdma_stop() method on the older chips,  taking into
account that the interrupt bits are not coupled to DMA and that's enough to read
the register to clear the interrupt (on the older chips).  Determine what method
to use at the driver load time.

Fix kernel-doc of the bmdma_stop() methods, while at it.

Subject: [PATCH 5152/6423] pata_cmd64x: implement sff_irq_clear() method

Convert the driver's two bmdma_stop() methods into sff_irq_clear() methods --
they shouldn't have been bothering with clearing interrupts from the very start;
the driver will now use the standard bmdma_stop() method implementation (where
appropriate).

Subject: [PATCH 5154/6423] USB: dynamically allocate usb_device children
 pointers instead of using a fix array

Non-hub device has no child, and even a real USB hub has ports far
less than USB_MAXCHILDREN, so there is no need using a fix array for
child devices, just allocate it dynamically according real port
number.

Subject: [PATCH 5160/6423] USB: ohci-nxp: Remove i2c_write(), use smbus

This patch removes the re-coded i2c_write function from the ohci-nxp driver
in favour of using just smbus functions.

Subject: [PATCH 5161/6423] usb gadget: fix a section mismatch when compiling
 g_ffs with CONFIG_USB_FUNCTIONFS_ETH
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

 commit 28824b18ac4705e876a282a15ea0de8fc957551f:
 |Author: Michal Nazarewicz <m.nazarewicz@samsung.com>
 |Date:   Wed May 5 12:53:13 2010 +0200
 |
 |    USB: gadget: __init and __exit tags removed
 |
 |    __init, __initdata and __exit tags have have been removed from
 |    various files to make it possible for gadgets that do not use
 |    the __init/__exit tags to use those.
 obviously missed (at least) this case leading to a section mismatch in
 g_ffs.c when compiling with CONFIG_USB_FUNCTIONFS_ETH enabled.

Subject: [PATCH 5162/6423] xfs: log file size updates at I/O completion time

Do not use unlogged metadata updates and the VFS dirty bit for updating
the file size after writeback.  In addition to causing various problems
with updates getting delayed for far too long this also drags in the
unscalable VFS dirty tracking, and is one of the few remaining unlogged
metadata updates.

Subject: [PATCH 5163/6423] serial: bfin-uart: Don't access tty circular buffer
 in TX DMA interrupt after it is reset.

When kernel reboot, tty circular buffer is reset before last TX DMA interrupt is called,
while the buffer tail is updated in TX DMA interrupt handler. So, don't update the buffer
tail if it is reset.

Subject: [PATCH 5165/6423] PM / Sleep: JBD and JBD2 missing set_freezable()

With the latest and greatest changes to the freezer, I started seeing
panics that were caused by jbd2 running post-process freezing and
hitting the canary BUG_ON for non-TuxOnIce I/O submission. I've traced
this back to a lack of set_freezable calls in both jbd and jbd2. Since
they're clearly meant to be frozen (there are tests for freezing()), I
submit the following patch to add the missing calls.

Subject: [PATCH 5166/6423] PM / QoS: Make it possible to expose PM QoS latency
 constraints

A runtime suspend of a device (e.g. an MMC controller) belonging to
a power domain or, in a more complicated scenario, a runtime suspend
of another device in the same power domain, may cause power to be
removed from the entire domain.  In that case, the amount of time
necessary to runtime-resume the given device (e.g. the MMC
controller) is often substantially greater than the time needed to
run its driver's runtime resume callback.  That may hurt performance
in some situations, because user data may need to wait for the
device to become operational, so we should make it possible to
prevent that from happening.

For this reason, introduce a new sysfs attribute for devices,
power/pm_qos_resume_latency_us, allowing user space to specify the
upper bound of the time necessary to bring the (runtime-suspended)
device up after the resume of it has been requested.  However, make
that attribute appear only for the devices whose drivers declare
support for it by calling the (new) dev_pm_qos_expose_latency_limit()
helper function with the appropriate initial value of the attribute.

Subject: [PATCH 5168/6423] sh_mmcif / PM: Use PM QoS latency constraint

Make sh_mmcif call dev_pm_qos_expose_latency_limit() to expose
the PM QoS latency limit to user space and specify the initial
value of it as 100 microseconds.

Subject: [PATCH 5169/6423] xfs: log timestamp updates

Timestamps on regular files are the last metadata that XFS does not update
transactionally.  Now that we use the delaylog mode exclusively and made
the log scode scale extremly well there is no need to bypass that code for
timestamp updates.  Logging all updates allows to drop a lot of code, and
will allow for further performance improvements later on.

Note that this patch drops optimized handling of fdatasync - it will be
added back in a separate commit.

  *
- * We need the barrier() to maintain correct ordering between unlogged
- * updates and the transaction commit code that clears the i_update_core

From 339a5f5dd9d3ac3d68a594d81507e1eab77ed223 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5170/6423] xfs: make xfs_inode_item_size idempotent

Move all code messing with the inode log item flags into xfs_inode_item_format
to make sure xfs_inode_item_size really only calculates the the number of
vectors, but doesn't modify any state of the inode item.

From f5d8d5c4bf29c9f7754d9cbe5e27c785106ba872 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@infradead.org>
Date: Wed, 29 Feb 2012 09:53:54 +0000
Subject: [PATCH 5171/6423] xfs: split in-core and on-disk inode log item
 fields

Add a new ili_fields member to the inode log item to isolate the in-memory
flags from the ones that actually go to the log.  This will allow tracking
timestamp-only updates for fdatasync and O_DSYNC in the next patch and
prepares for divorcing the on-disk log format from the in-memory log item
a little further down the road.

Subject: [PATCH 5175/6423] staging: drm/omap: use current time for page-flip
 event

Because we don't have vblank hooked up via drm_irq (which is a bit
awkward due to separation between omapdss (which knows the irq #)
and omapdrm, for now use gettimeofday to have a semi-sane timestamp
in the page-flip event.  Otherwise apps like weston drm compositor,
which use the timestamp in it's animations, get highly confused.

Subject: [PATCH 5180/6423] usb: Don't make USB_ARCH_HAS_{XHCI,OHCI,EHCI}
 depend on USB_SUPPORT.

The fact that an architecture/board has XHCI, OHCI or EHCI does not
depend on the fact that the kernel is configured with USB_SUPPORT.

Make the Kconfig reflect this fact thus avoiding ugly messages like:

warning: (MIPS_ALCHEMY && CAVIUM_OCTEON_REFERENCE_BOARD && SOC_AR71XX && SOC_AR724X && SOC_AR913X && SOC_AR933X) selects USB_ARCH_HAS_EHCI which has unmet direct dependencies (USB_SUPPORT)

Subject: [PATCH 5181/6423] regulator: tps65912: Use simple equations to get
 register address

The address of ctrl and sel registers can be calculated by simple equations.
This patch simplifies the implementation in tps65912_get_ctrl_register and
implements tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register
and tps65912_get_ldo_sel_register.

Subject: [PATCH 5183/6423] regulator: tps65910: Provide settling time for
 enabling rails

There is settling time for each rails when it is switched to
ON. Implementing enable time for returning proper settling time
of regulator rails when it is enabled.
Filling the on-time for each rail as per tps65910/tps65911
datasheets.

From 02e19f9c7cacfb33d7b2f5cace7972fa60f92319 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5185/6423] hvc_xen: implement multiconsole support

This patch implements support for multiple consoles:
consoles other than the first one are setup using the traditional xenbus
and grant-table based mechanism.
We use a list to keep track of the allocated consoles, we don't
expect too many of them anyway.

Changes in v3:

- call hvc_remove before removing the console from xenconsoles;
- do not lock xencons_lock twice in the destruction path;
- use the DEFINE_XENBUS_DRIVER macro.

Subject: [PATCH 5187/6423] xen/xenbus: ignore console/0

Unfortunately xend creates a bogus console/0 frotend/backend entry pair
on xenstore that console backends cannot properly cope with.
Any guest behavior that is not completely ignoring console/0 is going
to either cause problems with xenconsoled or qemu.
Returning 0 or -ENODEV from xencons_probe is not enough because it is
going to cause the frontend state to become 4 or 6 respectively.
The best possible thing we can do here is just ignore the entry from
xenbus_probe_frontend.

Since then any use of "variable length arrays" has become blasphemous.
Even in perfectly good, beautiful, perfectly safe code like the one
below where the variable length arrays are only used as a sizeof()
parameter, for type-safe dynamic structure allocations. GCC is not
executing any stack allocation code.

I have produced a small file which defines two functions main1(unsigned numdevs)
and main2(unsigned numdevs). main1 uses code as before with call to malloc
and main2 uses code as of after this patch. I compiled it as:
	gcc -O2 -S see_asm.c
and here is what I get:

<see_asm.s>
main1:
.LFB7:
	.cfi_startproc
	mov	%edi, %edi
	leaq	4(%rdi,%rdi), %rdi
	salq	$3, %rdi
	jmp	malloc
	.cfi_endproc
.LFE7:
	.size	main1, .-main1
	.p2align 4,,15
	.globl	main2
	.type	main2, @function
main2:
.LFB8:
	.cfi_startproc
	mov	%edi, %edi
	addq	$2, %rdi
	salq	$4, %rdi
	jmp	malloc
	.cfi_endproc
.LFE8:
	.size	main2, .-main2
	.section	.text.startup,"ax",@progbits
	.p2align 4,,15
</see_asm.s>

*Exact* same code !!!

So please seriously consider not accepting this patch and leave the
perfectly good code intact.

+A simple common binding for matrix-connected key boards. Currently targeted at

+Required properties:
+- linux,keymap: an array of packed 1-cell entries containing the equivalent

+  as:
+	row << 24 | column << 16 | key-code

Subject: [PATCH 5190/6423] Input: tegra-kbc - revise device tree support

This is an incremental patch updating to the revised bindings for
matrix keyboards.

This includes an optional "linux,fn-keymap" binding that is not yet
implemented, that will be used to specify the Fn-key modifier layout
if needed.

Subject: [PATCH 5193/6423] ixgbe: Do not disable read relaxed ordering when
 DCA is enabled

A previous fix had gone though and disabled relaxed ordering for Rx
descriptor read fetching.  This was not necessary as this functions
correctly and has no ill effects on the system.

In addition several of the defines used for the DCA control registers were
incorrect in that they indicated descriptor effects when they actually had
an impact on either data or header write back.  As such I have update these
to correctly reflect either DATA or HEAD.

There isn't much point in using variables to store the values of eitr_low
and eitr_high since they are not user changeable.  As such I am replacing
them with the constants 10 and 20 in order to avoid any confusion on what
the values actually are.

Subject: [PATCH 5197/6423] ixgbe: Fix race condition where RX buffer could
 become corrupted.

There was a race condition in the reset path where the RX buffer
could become corrupted during Fdir configuration.This is due to
a HW bug.The fix right now is to lock the buffer while we do the
fdir configuration.Since we were using similar workaround for another bug,
I moved the existing code to a function and reused it.HW team also recommended
that IXGBE_MAX_SECRX_POLL value be changed from 30 to 40.The erratum for this
bug will be published in the next release 82599 Spec Update

Subject: [PATCH 5198/6423] ixgbe: dcb: use DCB config values for FCoE traffic
 class on open

Disabling and enabling DCB can cause FCoE hardware initialization to
occur on the incorrect traffic class when the up2tc mapping has not
yet been reconfigured.

Fix this by using the DCB configuration maps that are correct
and will be pushed at mqprio after DCB driver setup completes
successfully.

Subject: [PATCH 5199/6423] x86/platform: Move APIC ID validity check into
 platform APIC code

Move APIC ID validity check into platform APIC code, so it can
be overridden when needed. For NumaChip systems, always trust
MADT, as it's constructed with high APIC IDs.

Behaviour verifies on standard x86 systems and on NumaChip
systems with this, and compile-tested with allyesconfig.

Subject: [PATCH 5200/6423] crypto: camellia - simplify key setup and
 CAMELLIA_ROUNDSM macro

camellia_setup_tail() applies 'inverse of the last half of P-function' to
subkeys, which is unneeded if keys are applied directly to yl/yr in
CAMELLIA_ROUNDSM.

Patch speeds up key setup and should speed up CAMELLIA_ROUNDSM as applying
key to yl/yr early has less register dependencies.

Quick tcrypt camellia results:
 x86_64, AMD Phenom II, ~5% faster
 x86_64, Intel Core 2, ~0.5% faster
 i386, Intel Atom N270, ~1% faster

Subject: [PATCH 5206/6423] crypto: camellia - add assembler implementation for
 x86_64

Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of
functions are provided. First set is regular 'one-block at time' encrypt/decrypt
functions. Second is 'two-block at time' functions that gain performance increase
on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way
functions with in-order CPUs.

Patch has been tested with tcrypt and automated filesystem tests.

Tcrypt benchmark results:

AMD Phenom II 1055T (fam:16, model:10):

Subject: [PATCH 5207/6423] padata: Fix race in the serialization path

When a padata object is queued to the serialization queue, another
cpu might process and free the padata object. So don't dereference
it after queueing to the serialization queue.

Subject: [PATCH 5208/6423] padata: Fix race on sequence number wrap

When padata_do_parallel() is called from multiple cpus for the same
padata instance, we can get object reordering on sequence number wrap
because testing for sequence number wrap and reseting the sequence
number must happen atomically but is implemented with two atomic
operations. This patch fixes this by converting the sequence number
from atomic_t to an unsigned int and protect the access with a
spin_lock. As a side effect, we get rid of the sequence number wrap
handling because the seqence number wraps back to null now without
the need to do anything.

Subject: [PATCH 5209/6423] regulator: Use tps65912_set_voltage_sel for both
 DCDCx and LDOx

commit 42b5ef "regulator: tps65912: Use simple equations to get register address"
uses tps65912_get_sel_register to replace tps65912_get_dcdc_sel_register
and tps65912_get_ldo_sel_register.

Now tps65912_set_voltage_dcdc_sel and tps65912_set_voltage_ldo_sel has exactly
the same implementation. Merge them to tps65912_set_voltage_sel function.

Subject: [PATCH 5211/6423] regulator: Add Anatop regulator driver

Anatop is an integrated regulator inside i.MX6 SoC.
There are 3 digital regulators which controls PU, CORE (ARM), and SOC.
And 3 analog regulators which controls 1P1, 2P5, 3P0 (USB).
This patch adds the Anatop regulator driver.

Subject: [PATCH 5213/6423] AppArmor: Fix error returned when a path lookup is
 disconnected

The returning of -ESATLE when a path lookup fails as disconnected is wrong.
Since AppArmor is rejecting the access return -EACCES instead.

This also fixes a bug in complain (learning) mode where disconnected paths
are denied because -ESTALE errors are not ignored causing failures that
can change application behavior.

Subject: [PATCH 5214/6423] AppArmor: Fix oops in policy unpack auditing

Post unpacking of policy a verification pass is made on x transition
indexes.  When this fails a call to audit_iface is made resulting in an
oops, because audit_iface is expecting a valid buffer position but
since the failure comes from post unpack verification there is none.

Make the position argument optional so that audit_iface can be called
from post unpack verification.

Move the path name lookup failure messages into the main path name lookup

Also rename aa_get_name to aa_path_name as it is not getting a reference
counted object with a corresponding put fn.

Subject: [PATCH 5223/6423] regulator: Refactor tps6507x to use one
 tps6507x_pmic_ops for all LDOs and DCDCs

All the callback functions implementation for DCDCx and LDOx are very similar,
I think it is ok to use one tps6507x_pmic_ops for all LDOs and DCDCs.
This refactor removes a couple of duplicated code.

Subject: [PATCH 5225/6423] xfs: use common code for quota statistics

Switch the quota code over to use the generic XFS statistics infrastructure.
While the legacy /proc/fs/xfs/xqm and /proc/fs/xfs/xqmstats interfaces are
preserved for now the statistics that still have a meaning with the current
code are now also available from /proc/fs/xfs/stats.

From f8739c3ce2ac9a01515b56026b6a066c0808234b Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@infradead.org>
Date: Tue, 13 Mar 2012 08:52:34 +0000
Subject: [PATCH 5226/6423] xfs: per-filesystem dquot LRU lists

Replace the global dquot lru lists with a per-filesystem one.

Note that the shrinker isn't wire up to the per-superblock VFS shrinker
infrastructure as would have problems summing up and splitting the counts
for inodes and dquots.  I don't think this is a major problem as the quota
cache isn't as interwinded with the inode cache as the dentry cache is,
because an inode that is dropped from the cache will generally release
a dquot reference, but most of the time it won't be the last one.

Subject: [PATCH 5227/6423] xfs: use per-filesystem radix trees for dquot
 lookup

Replace the global hash tables for looking up in-memory dquot structures
with per-filesystem radix trees to allow scaling to a large number of
in-memory dquot structures.

From 59a56802918100c1e39e68c30a2e5ae9f7d837f0 Mon Sep 17 00:00:00 2001
From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
Date: Fri, 3 Feb 2012 16:03:20 -0500
Subject: [PATCH 5229/6423] xen/acpi-processor: C and P-state driver that
 uploads said data to hypervisor.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This driver solves three problems:
 1). Parse and upload ACPI0007 (or PROCESSOR_TYPE) information to the
     hypervisor - aka P-states (cpufreq data).
 2). Upload the the Cx state information (cpuidle data).
 3). Inhibit CPU frequency scaling drivers from loading.

The reason for wanting to solve 1) and 2) is such that the Xen hypervisor
is the only one that knows the CPU usage of different guests and can
make the proper decision of when to put CPUs and packages in proper states.
Unfortunately the hypervisor has no support to parse ACPI DSDT tables, hence it
needs help from the initial domain to provide this information. The reason
for 3) is that we do not want the initial domain to change P-states while the
hypervisor is doing it as well - it causes rather some funny cases of P-states
transitions.

For this to work, the driver parses the Power Management data and uploads said
information to the Xen hypervisor. It also calls acpi_processor_notify_smm()
to inhibit the other CPU frequency scaling drivers from being loaded.

Everything revolves around the 'struct acpi_processor' structure which
gets updated during the bootup cycle in different stages. At the startup, when
the ACPI parser starts, the C-state information is processed (processor_idle)
and saved in said structure as 'power' element. Later on, the CPU frequency
scaling driver (powernow-k8 or acpi_cpufreq), would call the the
acpi_processor_* (processor_perflib functions) to parse P-states information
and populate in the said structure the 'performance' element.

Since we do not want the CPU frequency scaling drivers from loading
we have to call the acpi_processor_* functions to parse the P-states and
call "acpi_processor_notify_smm" to stop them from loading.

There is also one oddity in this driver which is that under Xen, the
physical online CPU count can be different from the virtual online CPU count.
Meaning that the macros 'for_[online|possible]_cpu' would process only
up to virtual online CPU count. We on the other hand want to process
the full amount of physical CPUs. For that, the driver checks if the ACPI IDs
count is different from the APIC ID count - which can happen if the user
choose to use dom0_max_vcpu argument. In such a case a backup of the PM
structure is used and uploaded to the hypervisor.

[v1-v2: Initial RFC implementations that were posted]
[v3: Changed the name to passthru suggested by Pasi Kärkkäinen <pasik@iki.fi>]
[v4: Added vCPU != pCPU support - aka dom0_max_vcpus support]
[v5: Cleaned up the driver, fix bug under Athlon XP]
[v6: Changed the driver to a CPU frequency governor]
[v7: Jan Beulich <jbeulich@suse.com> suggestion to make it a cpufreq scaling driver
     made me rework it as driver that inhibits cpufreq scaling driver]
[v8: Per Jan's review comments, fixed up the driver]
[v9: Allow to continue even if acpi_processor_preregister_perf.. fails]

From b84a3a96751f93071c1863f2962273973c8b8f5e Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@lst.de>

Subject: [PATCH 5230/6423] xfs: remove the per-filesystem list of dquots

Instead of keeping a separate per-filesystem list of dquots we can walk
the radix tree for the two places where we need to iterate all quota
structures.

From a05931ceb0160deadbd7798d60d01b17f2d81b09 Mon Sep 17 00:00:00 2001
From: Christoph Hellwig <hch@infradead.org>
Date: Tue, 13 Mar 2012 08:52:37 +0000
Subject: [PATCH 5231/6423] xfs: remove the global xfs_Gqm structure

If we initialize the slab caches for the quota code when XFS is loaded there
is no need for a global and reference counted quota manager structure.  Drop
all this overhead and also fix the error handling during quota initialization.

Subject: [PATCH 5243/6423] EXYNOS4X12: Add support cpufreq for EXYNOS4X12

This patch adds support cpufreq for EXYNOS4X12 SoCs. Basically,
the exynos-cpufreq.c is used commonly and exynos4x12-cpufreq.c
is used for EXYNOS4212(two Cortex-A9 cores) and EXYNOS4412(four
Cortex-A9 cores) SoCs.

From 562a6cbe1cf2edf0a87a659eb26095400322430e Mon Sep 17 00:00:00 2001
From: Jaecheol Lee <jc.lee@samsung.com>
Date: Sat, 10 Mar 2012 03:00:02 -0800
Subject: [PATCH 5244/6423] EXYNOS5250: Add support cpufreq for EXYNOS5250

This patch adds support cpufreq for EXYNOS5250 SoC. Basically,
the exynos-cpufreq.c is used commonly and exynos5250-cpufreq.c
is used for EXYNOS5250(two Cortex-A15 cores) SoC.

Subject: [PATCH 5246/6423] staging/mei: propagate error codes up in the write
 flow

Change mei_write_message's return type from bool to int
to enable propagation of the error code up to caller functions.
The function now returns -EIO when low level write fails and 0
on success.
A similar change is done in intermediate caller functions:
mei_send_flow_control, mei_connect, and mei_disconnect

This makes code more alike to typical Linux kernel error
handling.

Subject: [PATCH 5251/6423] USB: serial: mos7840: Fixed MCS7820 device attach
 problem

A MCS7820 device supports two serial ports and a MCS7840 device supports
four serial ports. Both devices use the same driver, but the attach function
in driver was unable to correctly handle the port numbers for MCS7820
device. This problem has been fixed in this patch and this fix has been
verified on x86 Linux kernel 3.2.9 with both MCS7820 and MCS7840 devices.

Subject: [PATCH 5252/6423] serial: PL011: clear pending interrupts

Chanho Min reported that when the boot loader transfers
control to the kernel, there may be pending interrupts
causing the UART to lock up in an eternal loop trying to
pick tokens from the FIFO (since the RX interrupt flag
indicates there are tokens) while in practice there are
no tokens - in fact there is only a pending IRQ flag.

This patch address the issue with a combination of two
patches suggested by Russell King that clears and mask
all interrupts at probe() and clears any pending error
and RX interrupts at port startup time.

We suspect the spurious interrupts are a side-effect of
switching the UART from FIFO to non-FIFO mode.

Subject: [PATCH 5253/6423] [IA64] Fix ISA IRQ trigger model and polarity
 setting

When handling Interrupt Source Override in MADT table, the default
ISA IRQ trigger model and polarity should be edge-rising.
Current IA64 implmentation doesn't follow the specification and
set default ISA IRQ trigger model as level-low. With that wrong
configuration and when system runs out of interrupt vectors,
it will cause vector sharing among edge triggered ISA IRQ and
level triggered PCI IRQ, then interrupt storm. So change the code
to follow the specification.

Add PID 0x6015, corresponding to the new series of FT-X chips
(FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X).  They all
appear as serial devices, and seem indistinguishable except for the
default product string stored in their EEPROM.  The baudrate
generation matches FT232RL devices.

Tested with a FT201X and FT230X at various baudrates (100 - 3000000).

Subject: [PATCH 5259/6423] TOMOYO: Return appropriate value to poll().

"struct file_operations"->poll() expects "unsigned int" return value.
All files in /sys/kernel/security/tomoyo/ directory other than
/sys/kernel/security/tomoyo/query and /sys/kernel/security/tomoyo/audit should
return POLLIN | POLLRDNORM | POLLOUT | POLLWRNORM rather than -ENOSYS.
Also, /sys/kernel/security/tomoyo/query and /sys/kernel/security/tomoyo/audit
should return POLLOUT | POLLWRNORM rather than 0 when there is no data to read.

We should use the 'ifdebug' wrapper rather than trying to inline
tests of nfs_debug, so that the code compiles correctly when we
don't define NFS_DEBUG.

Subject: [PATCH 5264/6423] ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link()

GFP_ATOMIC is used in snd_pcm_link() just because the kmalloc is
called inside a lock.  Since this function isn't too critical for
speed and is rarely called in practice, better to allocate the chunk
at first before spinlock and free it in error paths, so that
GFP_KERNEL can be used.

Subject: [PATCH 5270/6423] spi: sh-hspi: control spi clock more correctly

Current sh-hspi had used platform-specific speed.
This patch remove it, and use spi_transfer specific speed.
It removes unnecessary flags from struct sh_hspi_info,
but struct sh_hspi_info is still exist, since sh-hspi needs
platform info in the future.

Subject: [PATCH 5271/6423] spi: sh-hspi: modify write/read method

Current sh-hspi had wrong write/read method which was not linux standard.
If spi_transfer requests tx[2], rx[2] len=2,
then, driver should run tx[0], rx[0], tx[1], rx[1].
But current sh-hspi runs tx[0], tx[1], rx[0], rx[1].
This patch fixes it up.

When doing a mode set with the special fb id -1, reject the mode set if
no fb is currently bound to the crtc.

Also remove the pointless list traversal to find the current crtc based
on the current crtc :)

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change drm_mode_attachmode_crtc() to take an "all or nothing" approach.
If an error is returned, there are no side effects visible.

Also change the function to always duplicate the mode passed in.

Also change the function to not give up when it finds the first
connector without and encoder.

A simpler approach would be to just remove the function completely as
it's unused currently.

The blob property data is always allocated immediately after the object
header. No need for the extra indirection when accessing it, just use
a flexible array member.

Subject: [PATCH 5289/6423] udlfb: remove sysfs framebuffer device with USB
 .disconnect()

The USB graphics card driver delays the unregistering of the framebuffer
device to a workqueue, which breaks the userspace visible remove uevent
sequence. Recent userspace tools started to support USB graphics card
hotplug out-of-the-box and rely on proper events sent by the kernel.

The framebuffer device is a direct child of the USB interface which is
removed immediately after the USB .disconnect() callback. But the fb device
in /sys stays around until its final cleanup, at a time where all the parent
devices have been removed already.

To work around that, we remove the sysfs fb device directly in the USB
.disconnect() callback and leave only the cleanup of the internal fb
data to the delayed work.

Before:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 remove   /2-1.2:1.0/graphics/fb0 (graphics)

After:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)

a step towards correct hot unplug for USB devices, we need to
remove the userspace facing bits at the unplug time for correct
udev operation.

Subject: [PATCH 5291/6423] drm/modeset: add helper to unplug all connectors
 from sysfs

In order to get correct ordering at hot-unplug for userspace,
we need to tear down all the sysfs bits at the correct time.

This adds a helper to allow drivers to remove the sysfs nodes
for all connectors.

Subject: [PATCH 5292/6423] drm: add core support for unplugging a device (v2)

Two parts to this, one is simple unplug from sysfs for the device node.

The second adds an unplugged state, if we have device opens, we
just set the unplugged state and return, if we have no device
opens we drop the drm device.

If after a lastclose we discover we are unplugged we then
drop the drm device.

v2: use an atomic for unplugged and wrap it for users,
add checks on open + mmap + ioctl entry points.

Subject: [PATCH 5293/6423] drm/udl: initial UDL driver (v4)

This is an initial drm/kms driver for the displaylink devices.

Supports fb_defio,
supports KMS dumb interface
supports 24bpp via conversion to 16bpp, hw can do this better.
supports hot unplug using new drm core features.

On an unplug, it disables connector polling, unplugs connectors
from sysfs, unplugs fbdev layer (using Kay's API), drops all the
USB device URBs, and call the drm core to unplug the device.

This driver is based in large parts on udlfb.c so I've licensed
it under GPLv2.

+ * To the hardware, 0 for a size byte means 256
+ *
+ * Rather than 256 pixel commands which are either rl or raw encoded,
+ * the rlx command simply assumes alternating raw and rl spans within one cmd.
+ * This has a slightly larger header overhead, but produces more even results.
+ * It also processes all data (read and write) in a single pass.

WARNING: vmlinux.o(.text+0x526e77): Section mismatch in reference from the function prealloc_protection_domains() to the function .init.text:alloc_passthrough_domain()
The function prealloc_protection_domains() references
the function __init alloc_passthrough_domain().
This is often because prealloc_protection_domains lacks a __init
annotation or the annotation of alloc_passthrough_domain is wrong.

For interrupt remapping the enablement of the IOMMU MSI

be initialized before the io-apics are up and running. So
the code to setup the MSI is moved seperated from the
hardware-setup routine now.

Subject: [PATCH 5303/6423] rt2x00: Set IEEE80211_HW_REPORTS_TX_ACK_STATUS in
 rt2800

rt2800 already reports the tx ack status of each frame back to mac80211.
Advertise this by setting IEEE80211_HW_REPORTS_TX_ACK_STATUS for rt2800.
This allows some mac80211 features like frame loss notifications to work
with rt2800.

Subject: [PATCH 5308/6423] ath9k: Remove aggregation flags

SC_OP_TXAGGR and SC_OP_RXAGGR are not really needed.
The HT capabilities of the station and HW can be used instead.

Subject: [PATCH 5309/6423] ath9k: Fix multi-VIF BSS handling

mac80211 provides short preamble information and ERP protection
information on a per-BSS basis, which can be used. Remove flags
stored in the driver, which was incorrect since they were being used
in a global manner.

Subject: [PATCH 5311/6423] rt2x00: rt2800usb: rework txdone code

Patch change txdone code to make it similar like txdone in rt2800pci,
process only one entry from queue matching tx status.

Before we processed all pending entries from queue until PACKEDID match,
that caused that we do not report tx statuses correctly.

Subject: [PATCH 5312/6423] rt2x00: rt2800usb: rework txstatus code

Currently we read tx status register after each urb data transfer. As
callback procedure also trigger reading, that causing we have many
"threads" of reading status. To prevent that introduce TX_STATUS_READING
flags, and check if we are already in process of sequential reading
TX_STA_FIFO, before requesting new reads.

Change timer to hrtimer, that make TX_STA_FIFO overruns less possible.
Use 200 us for initial timeout, and then reschedule in 100 us period,
this values probably have to be tuned.

Make changes on txdone work. Schedule it from
rt2800usb_tx_sta_fifo_read_completed() callback when first valid status
show up. Check in callback if tx status timeout happens, and schedule
work on that condition too. That make possible to remove tx status
timeout from generic watchdog. I moved that to rt2800usb.

Loop in txdone work, that should prevent situation when we queue work,
which is already processed, and after finish work is not rescheduled
again.

Subject: [PATCH 5313/6423] rt2x00: rt2800usb: do not check packedid for
 aggregated frames

Tx statuses of aggregated subframes contain packetid of first subframe
in the AMPDU. We can not identify AMPDU subframes based on packedid, so
simply assume that status match first pending frame in the queue. Thats
mostly the same what 2800pci do.

Subject: [PATCH 5314/6423] rt2x00: rt2800usb: limit tx queues length

TX status fifo is limited to 16 elements. When we send more frames than
that, we can easily loose status, what is not good for rate scaling
algorithm.

On my testing the change does not degrade performance, actually make
is slightly better. Additionally with the patch I can see much less
various rt2x00 warnings in dmesg.

Subject: [PATCH 5315/6423] mac80211: Don't sample max throughput rate in
 minstrel_ht

The current max throughput rate is known to be good as otherwise it
wouldn't be the max throughput rate. Since rate sampling can introduce
some overhead (by adding RTS for example or due to not aggregating the
frame) don't sample the max throughput rate.

Subject: [PATCH 5316/6423] mac80211: add NULL terminator to debugfs_netdev
 write buf

Some debugfs write functions call kstrto* functions, which
assume the string is null-terminated. Make it valid by changing
ieee80211_if_write() to use static buffer instead of allocating
one, and set the last char to NULL.

(The write functions try to parse some integer/mac address,
so 64 bytes buffer should be enough)

Subject: [PATCH 5317/6423] mac80211: make uapsd_* keys per-vif

uapsd_queues and uapsd_max_sp_len are relevant only for managed
interfaces, and can be configured differently for each vif.

Move them from the local struct to sdata->u.mgd, and update
the debugfs functions accordingly.

Date: Wed, 14 Mar 2012 16:40:22 +0100
Subject: [PATCH 5319/6423] ath9k_hw: clean up tx completion interrupt handling

TXQ_FLAG_TXOKINT_ENABLE and TXQ_FLAG_TXERRINT_ENABLE are always set and
used together, and they share the same bitmask in enum ath9k_tx_queue_flags.
Simplify the code that tests for these flags.

Subject: [PATCH 5332/6423] libertas: remove dump_survey implementation

libertas provides a dump_survey implementation based on reading of
a RSSI value. However, this RSSI value is calculated based on the
last received beacon from the associated AP - it is not a good
way of surveying a channel in general, and even causes an error
if the card is not associated to a network.

As this is not appropriate as a survey, remove it. This fixes an
issue where something in userspace is repeatedly calling site-survey
during boot, resulting in many repeated errors as the RSSI value cannot
be read before associating.

Subject: [PATCH 5333/6423] xfs: fix inode lookup race

When we get concurrent lookups of the same inode that is not in the
per-AG inode cache, there is a race condition that triggers warnings
in unlock_new_inode() indicating that we are initialising an inode
that isn't in a the correct state for a new inode.

When we do an inode lookup via a file handle or a bulkstat, we don't
serialise lookups at a higher level through the dentry cache (i.e.
pathless lookup), and so we can get concurrent lookups of the same
inode.

The race condition is between the insertion of the inode into the
cache in the case of a cache miss and a concurrently lookup:

Thread 1			Thread 2
xfs_iget()
  xfs_iget_cache_miss()
    xfs_iread()
    lock radix tree
    radix_tree_insert()
				rcu_read_lock
				radix_tree_lookup
				lock inode flags
				XFS_INEW not set
				igrab()
				unlock inode flags
				rcu_read_unlock
				use uninitialised inode
				.....
    lock inode flags
    set XFS_INEW
    unlock inode flags
    unlock radix tree
  xfs_setup_inode()
    inode flags = I_NEW
    unlock_new_inode()
      WARNING as inode flags != I_NEW

This can lead to inode corruption, inode list corruption, etc, and
is generally a bad thing to occur.

Fix this by setting XFS_INEW before inserting the inode into the
radix tree. This will ensure any concurrent lookup will find the new
inode with XFS_INEW set and that forces the lookup to wait until the
XFS_INEW flag is removed before allowing the lookup to succeed.

 xfs_attrmulti_attr_get

xfsdump uses for a large buffer for extended attributes, which has a
kmalloc'd shadow buffer in the kernel. This can fail after the
system has been running for some time as it is a high order
allocation. Add a fallback to vmalloc so that it doesn't require
contiguous memory and so won't randomly fail while xfsdump is
running.

Subject: [PATCH 5337/6423] gianfar: Add support for byte queue limits.

Add support for byte queue limits (BQL), based on the similar
modifications made to intel/igb/igb_main.c from Eric Dumazet
in commit bdbc063129e811264cd6c311d8c2d9b95de01231
	"igb: Add support for byte queue limits."

A local variable for tx_queue->qindex was introduced in
gfar_clean_tx_ring, since it is now used often enough to warrant it,
and it cleans up the readability somewhat as well.

There were two version strings, and neither one was being used.
Also in the same proximity were some unused #define that were
left over from the past.  Delete them all.

Subject: [PATCH 5342/6423] USB: use generic platform driver on ath79

The ath79 usb driver doesn't do anything special and is now converted
to the generic ehci and ohci driver.
This was tested on a TP-Link TL-WR1043ND (AR9132)

Subject: [PATCH 5343/6423] xfs: fallback to vmalloc for large buffers in
 xfs_getbmap

xfs_getbmap uses for a large buffer for extents, which is kmalloc'd.
This can fail after the system has been running for some time as it
is a high order allocation. Add a fallback to vmalloc so that it
doesn't require contiguous memory and so won't randomly fail on
files with large extent lists.

Subject: [PATCH 5344/6423] TTY: Wrong unicode value copied in con_set_unimap()

Bugzilla 40012: PIO_UNIMAP bug: error updating Unicode-to-font map
https://bugzilla.kernel.org/show_bug.cgi?id=40012

The unicode font map for the virtual console is a 32x32x64 table which
allocates rows dynamically as entries are added.  The unicode value
increases sequentially and should count all entries even in empty
rows.  The defect is when copying the unicode font map in con_set_unimap(),
the unicode value is not incremented properly.  The wrong unicode value
is entered in the new font map.

Subject: [PATCH 5353/6423] spi/fsl-espi: make the clock computation easier to

The -1 +1 thingy should probably do what DIV_ROUND_UP does. The 4 is 2
the  "platform_clock => sysclock" and 2 from the computation part. The 64
is the same 4 times 16.

The reference manual says that pm has to stay within 2 and 32. So the
lowest frequency is 32 and DIV16 set, the highest is 2 and DIV16 unset.

These drivers are specific to the PowerPC legacy iSeries platform and
their Kconfig is specified in arch/powerpc.  Legacy iSeries is being
removed, so these drivers can no longer be selected.

Subject: [PATCH 5357/6423] powerpc: Fix power4/970 idle code regression with
 lockdep

in commit 7230c5644188cd9e3fb380cc97dde00c464a3ba7
"powerpc: Rework lazy-interrupt handling"

I introduced a regression, accidentally calling irq tracing twice
and not properly restoring a clobbered register (r7) later used
for writing to the MSR.

This caused lockups when booting on a G5 with lockdep enabled.

Subject: [PATCH 5362/6423] target: Remove hack to make READ CAPACITY(10) lie
 if thin provisioning is enabled

Remove the hack that has READ CAPACITY(10) return 0xFFFFFFFF as the
number of sectors when thin provisioning is enabled.  This is supposed
to trigger the initiator to use READ CAPACITY(16) in this case so that
it finds out about thin provisioning.  But an initiator that cares about
thin provisioning is going to ask anyway, and an initiator that doesn't
know about READ CAPACITY(16) is going to get the wrong capacity.  So
just have READ CAPACITY(10) return the size it's supposed to.

Subject: [PATCH 5364/6423] target: Use array_zalloc for tpg_lun_list

Turns an order-10 allocation into slab-sized ones, thereby preventing
allocation failures with memory fragmentation.

This likely saves memory as well, as the slab allocator can pack objects
more tightly than the buddy allocator.

Subject: [PATCH 5365/6423] target: Use array_zalloc for device_list

Turns an order-8 allocation into slab-sized ones, thereby preventing
allocation failures with memory fragmentation.

This likely saves memory as well, as the slab allocator can pack objects
more tightly than the buddy allocator.

(nab: Fix lio-core patch fuzz)

Subject: [PATCH 5366/6423] target: remove obvious warnings

Get rid of a bunch of write-only variables.  In a number of cases I
suspect actual bugs to be present, so I left all of those for a second
look.

(nab: fix lio-core patch fuzz)

Subject: [PATCH 5367/6423] iscsi-target: Remove unused variables in
 iscsi_target_parameters.c

local_right_val was an obvious case, tmp_ptr is also write-only, but
evades the compiler by being passed to simple_strtoul as char **endp.

Subject: [PATCH 5368/6423] asix: asix_rx_fixup surgery to reduce skb truesizes

asix_rx_fixup() is complex, and does some unnecessary memory copies (at
least on x86 where NET_IP_ALIGN is 0)

Also, it tends to provide skbs with a big truesize (4096+256 with
MTU=1500) to upper stack, so incoming trafic consume a lot of memory and
I noticed early packet drops because we hit socket rcvbuf too fast.

Switch to a different strategy, using copybreak so that we provide nice
skbs to upper stack (including the NET_SKB_PAD to avoid future head
reallocations in some paths)

With this patch, I no longer see packets drops or tcp collapses on
various tcp workload with a AX88772 adapter.

From 313162d0b83836e2f57e51b9b8650fb4b9c396ea Mon Sep 17 00:00:00 2001
From: Paul Gortmaker <paul.gortmaker@windriver.com>

Subject: [PATCH 5377/6423] device.h: audit and cleanup users in main include
 dir

The <linux/device.h> header includes a lot of stuff, and
it in turn gets a lot of use just for the basic "struct device"
which appears so often.

Clean up the users as follows:

1) For those headers only needing "struct device" as a pointer
in fcn args, replace the include with exactly that.

2) For headers not really using anything from device.h, simply
delete the include altogether.

3) For headers relying on getting device.h implicitly before
being included themselves, now explicitly include device.h

4) For files in which doing #1 or #2 uncovers an implicit
dependency on some other header, fix by explicitly adding
the required header(s).

Any C files that were implicitly relying on device.h to be
present have already been dealt with in advance.

Total removals from #1 and #2: 51.  Total additions coming
from #3: 9.  Total other implicit dependencies from #4: 7.

As of 3.3-rc1, there were 110, so a net removal of 42 gives
about a 38% reduction in device.h presence in include/*

Subject: [PATCH 5380/6423] xen kconfig: relax INPUT_XEN_KBDDEV_FRONTEND deps

PV-on-HVM guests may want to use the xen keyboard/mouse frontend, but
they don't use the xen frame buffer frontend. For this case it doesn't
make much sense for INPUT_XEN_KBDDEV_FRONTEND to depend on
XEN_FBDEV_FRONTEND. The opposite direction always makes more sense, i.e.
if you're using xenfb, then you'll want xenkbd. Switch the dependencies.

Subject: [PATCH 5382/6423] powerpc/85xx: Adds Support for P2020RDB-PC board

P2020RDB-PC Board shares the same design(PCB) as P102x RDB style platforms.
The difference between this platform and the already existing P2020RDB
is mainly with respect to DDR. The P2020RDB-PC has a DDR3 memory.
The P2020RDB-PC also has a CPLD device connected to local bus.

The main differences from the P102x RDB-PC is 64-bit DDR and SYSCLK of
100Mhz.

Subject: [PATCH 5389/6423] powerpc/85xx: p2020rdb - move the NAND address.

It is not at 0xffa00000. According to current u-boot source the NAND
controller is always at 0xff800000 and it is either at CS0 or CS1
depending on NAND or NAND+NOR mode. In 36bit mode it is shifted to
0xfff800000 but it has always an eight there and never an A.

Subject: [PATCH 5390/6423] powerpc/85xx: p2020rdb & p1010rdb - lower spi flash
 freq to 40Mhz

This is here most likely since the FSL bsp. Back in the FSL bsp it was
set to 50Mhz and working. However the driver divided the SoC freq. only
by 2. According to the TRM the platform clock (which the manual refers
in its formula) is the system clock divided by two. So in the end it has
to divide by 4 and this is what the fsl-spi driver in tree is doing.
Since then the flash is not wokring I guess. After chaning the freq from
50Mhz to 40Mhz like others do then I can access the flash.

Fix typo introduced by "powerpc: Add TBI PHY node to first MDIO bus"
from Andy Fleming.
It's device_type rather than device-type, which causes the mdio probe to
fail thus making all gianfar ethernet interfaces unusable.

From 4a170d0198330b8615778f6f0e265cdaadfd54b4 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5395/6423] powerpc/85xx: create 32-bit DTS for the P1022DS

Create a 32-bit address space version of p1022ds.dts.  To avoid confusion,
p1022ds.dts is renamed to p1022ds_36b.dts.  We also create p1022ds.dtsi
to store some common nodes.

Subject: [PATCH 5396/6423] powerpc/85xx: p1022ds: disable the NOR flash node
 if video is enabled

The Freescale P1022 has a unique pin muxing "feature" where the DIU video
controller's video signals are muxed with 24 of the local bus address signals.
When the DIU is enabled, the bulk of the local bus is disabled, preventing
access to memory-mapped devices like NOR flash and the pixis FPGA.

Therefore, if the DIU is going to be enabled, then memory-mapped devices on
the localbus, like NOR flash, need to be disabled.

This also means that the localbus is not a 'simple-bus' any more, so remove
that string from the compatible node.

From d1fb10609ae189c1294c793f833a5c6b1bc71001 Mon Sep 17 00:00:00 2001
From: Jerry Huang <Chang-Ming.Huang@freescale.com>
Date: Wed, 14 Mar 2012 17:08:27 +0800
Subject: [PATCH 5399/6423] powerpc/85xx: add P1020MBG-PC platform support

The p1020mbg-pc has the similar feature as the p1020rdb.
Therefore, p1020mbg-pc use the same platform file as the p1/p2 rdb board.
Overview of P1020MBG-PC platform:
        - DDR3 2GB
        - NOR flash 64MB
        - I2C EEPROM 256Kb
        - eTSEC1 (RGMII PHY) connected to VSC7385 L2 switch
        - eTSEC2 (SGMII PHY)
        - eTSEC3 (RGMII PHY)
        - SDHC
        - 2 USB ports
        - 4 TDM ports
        - PCIe (Lane1 to dual SATA controller)

Subject: [PATCH 5400/6423] powerpc/85xx: add P1020UTM-PC platform support

The p1020utm-pc has the similar feature as the p1020rdb.
Therefore, p1020utm-pc use the same platform file as the p1/p2 rdb board.
Overview of P1020UTM-PC platform:
        - DDR3 1GB
        - NOR flash 32MB
        - I2C EEPROM 256Kb
        - eTSEC1 (RGMII PHY Atheros AR8021)
        - eTSEC2 (SGMII PHY Vitesse VSC8221)
        - eTSEC3 (RGMII PHY Atheros AR8021)
        - SDHC
        - 2 USB ports
        - PCIe (Lane1 to dual SATA controller)

Subject: [PATCH 5403/6423] powerpc: Add GE FPGA config option

This patch adds the GE_FPGA configuration option. This is being carried
out as ground work to allow the PIC and GPIO drivers to be move from the
powerpc 86xx platform directory to more general locations to allow them to
be used on non-86xx boards and to reduce churn when further boards using
these drivers are added.

 subsystem

The GE GPIO driver provides basic support (set direction, read/write state)
for the GPIO provided on some GE single board computers. This patch moves
the driver from the 86xx specific platform directrory to the GPIO subsystem
so that it can be used on non-86xx boards.

Subject: [PATCH 5407/6423] powerpc/85xx: p1022ds: enable monitor switching via
 pixis indirect mode

When the P1022's DIU video controller is active, the pixis must be accessed
in "indirect" mode, which uses localbus chip select addresses.

Switching between the DVI and LVDS monitor ports is handled by the pixis,
so that switching needs to be done via indirect mode.

This has the side-effect of no longer requiring U-Boot to enable the DIU.
Now Linux can enable the DIU all by itself.

Subject: [PATCH 5409/6423] regulator: Fix up a confusing dev_warn when DT
 lookup fails

of_parse_phandle() returns NULL either if the property name
itself does not exist or if it (exists and) does not
reference a valid phandle.
Giving out a warn like the one below (that the property references
an invalid phandle) can be confusing when the property itself
does not exist in the node.
Fix it with a more sensible message and make it a dev_dbg instead
of a dev_warn.

Subject: [PATCH 5410/6423] powerpc/83xx: mpc836x - fix failed phy detection
 for ucc ethernet on MDS

The mpc836x_mds platform has been broken since the commit
6fe3264945ee63292cdfb27b6e95bc52c603bb09

  "netdev/phy: Use mdiobus_read() so that proper locks are taken"

which caused the fsl_pq_mdio TBI autoprobe to oops.  The oops
was "fixed" in commit 28d8ea2d568534026ccda3e8936f5ea1e04a86a1

  "fsl_pq_mdio: Clean up tbi address configuration"

by simply removing the the autoscan code, and making tbi nodes
mandatory.  Some of the newer reference platforms were updated
to have tbi nodes in 220669495bf8b68130a8218607147c7b74c28d2b

  "powerpc: Add TBI PHY node to first MDIO bus"

but the older mpc836x didn't get one and hence was just failing
with -EBUSY as follows:

 fsl-pq_mdio: probe of e0102120.mdio failed with error -16
   ...
 net eth0: Could not attach to PHY
 eth0: Cannot initialize PHY, aborting.

Add a TBI node and use the 1st free address for it.

Subject: [PATCH 5415/6423] powerpc/85xx: allow CONFIG_PHYS_64BIT to be
 selectable

Remove the "select PHYS_64BIT" from the Kconfig entry for the P1022DS,
so that large physical address support is a selectable option for non-CoreNet
reference boards.

The option is enabled in mpc85xx_[smp_]defconfig so that the default is
unchanged.  However, now it can be deselected.

The P1022DS had this option defined because the default device tree for
this board uses 36-bit addresses.  This had the side-effect of forcing
this option on for all boards that use mpc85xx_[smp_]defconfig.  Some
users may want to disable this feature to create an optimized configuration
for boards with <= 2GB of RAM.

Subject: [PATCH 5418/6423] x86, efi: Fix pointer math issue in
 handle_ramdisks()

"filename" is a efi_char16_t string so this check for reaching the end
of the array doesn't work.  We need to cast the pointer to (u8 *) before
doing the math.

This patch changes the "filename" to "filename_16" to avoid confusion in
the future.

 messages in the driver

Support the newly defined KVP message types. It turns out that the host
pushes a set of standard key value pairs as soon as the guest opens the KVP channel.
Since we cannot handle these tuples until the user level daemon loads up, defer
reading the KVP channel until the user level daemon is launched.

From db425334e5bb7fa65bbbd7bea9d79842f65bcf45 Mon Sep 17 00:00:00 2001
From: "K. Y. Srinivasan" <kys@microsoft.com>
Date: Fri, 16 Mar 2012 08:02:26 -0700
Subject: [PATCH 5424/6423] Tools: hv: Fully support the new KVP verbs in the
 user level daemon

Now fully support the new KVP messages in the user level daemon. Hyper-V defines
multiple persistent pools to which the host can write/read/modify KVP tuples.
In this patch we implement a file for each specified pool, where the KVP tuples
will be stored in the guest.

ZTE have yet to discover the magic of USB descriptors.  These
devices use ff/ff/ff for class/subclass/protocol regardless of
function, except for usb-storage.  Use an interface number
whitelist to force the driver to bind only to the QMI/wwan
interface.

Subject: [PATCH 5427/6423] PM / Domains: Fix handling of wakeup devices during
 system resume

During system suspend pm_genpd_suspend_noirq() checks if the given
device is in a wakeup path (i.e. it appears to be needed for one or
more wakeup devices to work or is a wakeup device itself) and if it
needs to be "active" for wakeup to work.  If that is the case, the
function returns 0 without incrementing the device domain's counter
of suspended devices and without executing genpd_stop_dev() for the
device.  In consequence, the device is not stopped (e.g. its clock
isn't disabled) and power is always supplied to its domain in the
resulting system sleep state.

However, pm_genpd_resume_noirq() doesn't repeat that check and it
runs genpd_start_dev() and decrements the domain's counter of
suspended devices even for the wakeup device that weren't stopped by
pm_genpd_suspend_noirq().  As a result, the start callback may be run
unnecessarily for them and their domains' counters of suspended
devices may become negative.  Both outcomes aren't desirable, so fix
pm_genpd_resume_noirq() to look for wakeup devices that might not be
stopped by during system suspend.

Subject: [PATCH 5428/6423] PM / Domains: Fix hibernation restore of devices,
 v2

During resume from hibernation pm_genpd_restore_noirq() should only
power off domains whose suspend_power_off flags are set once and
not every time it is called for a device in the given domain.
Moreover, it shouldn't decrement genpd->suspended_count, because
that field is not touched during device freezing and therefore it is
always equal to 0 when pm_genpd_restore_noirq() runs for the first
device in the given domain.

This means pm_genpd_restore_noirq() may use genpd->suspended_count
to determine whether or not it it has been called for the domain in
question already in this cycle (it only needs to increment that
field every time it runs for this purpose) and whether or not it
should check if the domain needs to be powered off.  For that to
work, though, pm_genpd_prepare() has to clear genpd->suspended_count
when it runs for the first device in the given domain (in which case
that flag need not be cleared during domain initialization).

Subject: [PATCH 5429/6423] PM / Domains: Introduce "always on" device flag

The TMU device on the Mackerel board belongs to the A4R power domain
and loses power when the domain is turned off.  Unfortunately, the
TMU driver is not prepared to cope with such situations and crashes
the system when that happens.  To work around this problem introduce
a new helper function, pm_genpd_dev_always_on(), allowing a device
driver to mark its device as "always on" in case it belongs to a PM
domain, which will make the generic PM domains core code avoid
powering off the domain containing the device, both at run time and
during system suspend.

Subject: [PATCH 5430/6423] PM / shmobile: Make TMU driver use
 pm_genpd_dev_always_on()

Make the TMU clocksource driver mark its device as "always on"
using pm_genpd_dev_always_on() to protect it from surprise power
removals and make sh7372_add_standard_devices() add TMU devices on
sh7372 to the A4R power domain so that their "always on" flags
are taken into account as appropriate.

Subject: [PATCH 5433/6423] powerpc/85xx: mpc85xxcds - Fix PCI I/O space
 resource of PCI bridge

There is a PCI bridge(Tsi310) between the MPC8548 and a VIA
southbridge chip.

The bootloader sets the PCI bridge to open a window from 0x0000
to 0x1fff on the PCI I/O space. But the kernel can't set the I/O
resource. In the routine pci_read_bridge_io(), if the base which
is read from PCI_IO_BASE is equal to zero, the routine don't set
the I/O resource of the child bus.

To allow the legacy I/O space on the VIA southbridge to be accessed,
use the fixup to fix the PCI I/O space of the PCI bridge.

Subject: [PATCH 5440/6423] powerpc/fsl: Added aliased MSIIR register address
 to MSI node in dts

The MSIIR register for each MSI bank is aliased to a different
address. The MSI node reg property was updated to contain this
address:

e.g. reg = <0x41600 0x200 0x44140 4>;

The first region contains the address and length of the MSI
register set and the second region contains the address of
the aliased MSIIR register at 0x44140.

Subject: [PATCH 5441/6423] powerpc: add support for MPIC message register API

Some MPIC implementations contain one or more blocks of message registers
that are used to send messages between cores via IPIs.  A simple API has
been added to access (get/put, read, write, etc ...) these message registers.
The available message registers are initially discovered via nodes in the
device tree.  A separate commit contains a binding for the message register
nodes.

+* FSL MPIC Message Registers
+
+This binding specifies what properties must be available in the device tree
+representation of the message register blocks found in some FSL MPIC
+implementations.
+
+Required properties:
+
+    - compatible: Specifies the compatibility list for the message register
+      block.  The type shall be <string-list> and the value shall be of the form
+      "fsl,mpic-v<version>-msgr", where <version> is the version number of
+      the MPIC containing the message registers.
+
+    - reg: Specifies the base physical address(s) and size(s) of the
+      message register block's addressable register space.  The type shall be
+      <prop-encoded-array>.
+
+    - interrupts: Specifies a list of interrupt-specifiers which are available
+      for receiving interrupts. Interrupt-specifier consists of two cells: first
+      cell is interrupt-number and second cell is level-sense. The type shall be
+      <prop-encoded-array>.
+
+Optional properties:
+
+    - mpic-msgr-receive-mask: Specifies what registers in the containing block
+      are allowed to receive interrupts. The value is a bit mask where a set
+      bit at bit 'n' indicates that message register 'n' can receive interrupts.
+      Note that "bit 'n'" is numbered from LSB for PPC hardware. The type shall
+      be <u32>. If not present, then all of the message registers in the block
+      are available.
+
+Aliases:
+
+    An alias should be created for every message register block.  They are not
+    required, though.  However, a particular implementation of this binding
+    may require aliases to be present.  Aliases are of the form
+    'mpic-msgr-block<n>', where <n> is an integer specifying the block's number.
+    Numbers shall start at 0.
+
+Example:
+
+	aliases {
+		mpic-msgr-block0 = &mpic_msgr_block0;
+		mpic-msgr-block1 = &mpic_msgr_block1;
+	};
+
+	mpic_msgr_block0: mpic-msgr-block@41400 {
+		compatible = "fsl,mpic-v3.1-msgr";
+		reg = <0x41400 0x200>;
+		// Message registers 0 and 2 in this block can receive interrupts on
+		// sources 0xb0 and 0xb2, respectively.
+		interrupts = <0xb0 2 0xb2 2>;
+		mpic-msgr-receive-mask = <0x5>;
+	};
+
+	mpic_msgr_block1: mpic-msgr-block@42400 {
+		compatible = "fsl,mpic-v3.1-msgr";
+		reg = <0x42400 0x200>;
+		// Message registers 0 and 2 in this block can receive interrupts on
+		// sources 0xb4 and 0xb6, respectively.
+		interrupts = <0xb4 2 0xb6 2>;
+		mpic-msgr-receive-mask = <0x5>;
+	};

Subject: [PATCH 5444/6423] pstore: Introduce get_reason_str() to pstore

Recently, there has been some changes in kmsg_dump() below and they have been applied to linus-tree.
 (1) kmsg_dump(KMSG_DUMP_KEXEC) was removed.
     http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=a3dd3323058d281abd584b15ad4c5b65064d7a61

 (2) The order of "enum kmsg_dump_reason" was modified.
     http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=c22ab332902333f83766017478c1ef6607ace681

Replace the fragile reason_str array with a more robust solution that
will not be broken by future re-arrangements of the enum values.

Subject: [PATCH 5445/6423] ARM: 7362/1: AMBA: Add module_amba_driver() helper
 macro for amba_driver

For simple modules that contain a single amba_driver without any
additional setup code then ends up being a block of duplicated
boilerplate. This patch adds a new macro, module_amba_driver(),
which replaces the module_init()/module_exit() registrations with
template functions.

Subject: [PATCH 5447/6423] netxen: qlogic ethernet : Fix endian bug.

Change the datatype of "ip_addr" to __be32 as 'ip' should be in
big endian format.

Adapter needs "ip address" in big endian format stored at lower 32bit
of req.word[1]. netxen_config_ipaddr() now receives 'ip' in big endian
format. To satisfy adapter's need, use memcpy() to copy byte by byte
of 'ip' into lower 32bit of req.word[1].

Mac address and serial number of adapter need to be in little endian format.
Change the data type of the related  variables to __le32 / __le64 or cast it
explicitly to __le32 / __le64 depending upon the requirement.

Subject: [PATCH 5448/6423] stmmac: Add device-tree support

This patch adds support to configure the STMMAC ethernet driver via
device-tree instead of platform_data.

Currently, only the properties needed on SPEAr600 are provided. All
other properties should be added once needed on other platforms.

Subject: [PATCH 5450/6423] Input: kxtj9 - who_am_i check value and initial
 data rate fixes

Several fixes based on customer feedback:

* WHO_AM_I value has changed since preliminary parts used for initial
  testing;

* Output of le16_to_cpu must be saved to memory before shifting to
  preserve sign;

* Initial data rate was not extracted from data control register init.
  This was causing the initial data rate to be set to maximum until
  it was changed. To fix this problem, it made more sense to specify
  initial data rate and extract the register mask from that.

 netif_start_queue
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

If host is going to autosuspend function with two interfaces and
if IP packet has arrived in-between of two usbnet_suspend() callbacks,
i.e usbnet_resume() is called in-between, tx data flow is stopped.
When autosuspend timer expires and device is put to autosuspend
again, tx queue is waked up and data can be sent again.
This behavior might be repeated several times in a row.

Tested on Intel/ARM.

Subject: [PATCH 5453/6423] arp: allow arp processing to honor per interface
 arp_accept sysctl

I found recently that the arp_process function which handles all of our received
arp frames, is using IPV4_DEVCONF_ALL macro to check the state of the arp_process
flag.  This seems wrong, as it implies that either none or all of the network
interfaces accept gratuitous arps.  This patch corrects that, allowing
per-interface arp_accept configuration to deviate from the all setting.  Note
this also brings us into line with the way the arp_filter setting is handled
during arp_process execution.

Tested this myself on my home network, and confirmed it works as expected.

Subject: [PATCH 5454/6423] Input: convert SPI drivers to use
 module_spi_driver()

This patch converts the drivers in drivers/input/* to use the
module_spi_driver() macro which makes the code smaller and a bit
simpler.

Instead of having to define the match table to NULL if CONFIG_OF isn't
set, use the of_match_ptr() macro which will do this for us.

From f800326dca7bc158f4c886aa92f222de37993c80 Mon Sep 17 00:00:00 2001
From: Alexander Duyck <alexander.h.duyck@intel.com>
Date: Sat, 3 Mar 2012 02:35:52 +0000
Subject: [PATCH 5464/6423] ixgbe: Replace standard receive path with a page
 based receive

This patch replaces the existing Rx hot-path in the ixgbe driver with a new
implementation that is based on performing a double buffered receive.  The
ixgbe driver already had something similar in place for its' packet split
path, however in that case we were still receiving the header for the
packet into the sk_buff.  The big change here is the entire receive path
will receive into pages only, and then pull the header out of the page and
copy it into the sk_buff data.  There are several motivations behind this
approach.

First, this allows us to avoid several cache misses as we were taking a
set of cache misses for allocating the sk_buff and then another set for
receiving data into the sk_buff.  We are able to avoid these misses on
receive now as we allocate the sk_buff when data is available.

Second we are able to see a considerable performance gain when an IOMMU is
enabled because we are no longer unmapping every buffer on receive.
Instead we can delay the unmap until we are unable to use the page, and
instead we can simply call sync_single_range on the half of the page that
contains new data.

Finally we are able to drop a considerable amount of code from the driver
as we no longer have to support 2 different receive modes, packet split and
one buffer.  This allows us to optimize the Rx path further since less
branching is required.

Subject: [PATCH 5467/6423] ixgbe: Modify setup of descriptor flags to avoid
 conditional jumps

This change makes it more likely that the descriptor flags setup will use
cmov instructions instead of conditional jumps when setting up the flags.
The advantage to this is that the code should just flow a bit more
smoothly.

To do this it is necessary to set the TX_FLAGS_CSUM bit in tx_flags when
doing TSO so that we also do the checksum in addition to the segmentation
offload.

Instead of keeping a local copy of the skb on the stack for as long as long
as we do it makes sense to instead just place it on the first tx_buffer
structure so that we can save space on the stack and avoid unnecessary
read/write operations copying the pointer out of the stack and onto the
ring later.

Subject: [PATCH 5470/6423] ixgbe: Write gso_segs and bytcount to the ring
 sooner

This change makes it so that gso_segs and bytecount are written to the ring
sooner.  This helps to simplify the logic for the two since segmentation
offloads can now update them within their own function.

Subject: [PATCH 5472/6423] ixgbe: always write DMA for single_mapped value
 with skb

This change makes it so that we always write the DMA address for the skb
itself on the same tx_buffer struct that the skb is written on.  This way
we don't need the MAPPED_AS_PAGE flag and we always know it will be the
first DMA value that we will have to unmap.

In addition I have found an issue in which we were leaking a DMA mapping if
the value happened to be 0 which is possible on some platforms.  In order
to resolve that I have updated the transmit path to use the length instead
of the DMA mapping in order to determine if a mapping is actually present.

One other tweak in this patch is that it only writes the olinfo information
on the first descriptor.  As it turns out it isn't necessary to write it
for anything but the first descriptor so there is no need to carry it
forward.

Subject: [PATCH 5473/6423] firewire: ohci: fix too-early completion of IR
 multichannel buffers

handle_ir_buffer_fill() assumed that a completed descriptor would be
indicated by a non-zero transfer_status (as in most other descriptors).
However, this field is written by the controller as soon as (the end of)
the first packet has been written into the buffer.  As a consequence, if
we happen to run into such a descriptor when the interrupt handler is
executed after such a packet has completed, the descriptor would be
taken out of the list of active descriptors as soon as the buffer had
been partially filled, so the event for the buffer being completely
filled would never be sent.

To fix this, handle descriptors only when they have been completely
filled, i.e., when res_count == 0.  (This also matches the condition
that is reported by the controller with an interrupt.)

Subject: [PATCH 5474/6423] firewire: cdev: fix IR multichannel event
 documentation

State more precisely when fw_cdev_event_iso_interrupt_mc is sent.
While the comment tried to reflect an amibuity in the OHCI
specification, there is only one method that is useful in practice,
and this also matches all the hardware implementations I've tested.

Subject: [PATCH 5479/6423] NFSv4.1: Clean ups and bugfixes for the pNFS
 read/writeback/commit code

Move more pnfs-isms out of the generic commit code.

Bugfixes:

- filelayout_scan_commit_lists doesn't need to get/put the lseg.
  In fact since it is run under the inode->i_lock, the lseg_put()
  can deadlock.

- Ensure that we distinguish between what needs to be done for
  commit-to-data server and what needs to be done for commit-to-MDS
  using the new flag PG_COMMIT_TO_DS. Otherwise we may end up calling
  put_lseg() on a bucket for a struct nfs_page that got written
  through the MDS.

- Fix a case where we were using list_del() on an nfs_page->wb_list
  instead of list_del_init().

- filelayout_initiate_commit needs to call filelayout_commit_release
  on error instead of the mds_ops->rpc_release(). Otherwise it won't
  clear the commit lock.

Cleanups:

- Let the files layout manage the commit lists for the pNFS case.
  Don't expose stuff like pnfs_choose_commit_list, and the fact
  that the commit buckets hold references to the layout segment
  in common code.

- Cast out the put_lseg() calls for the struct nfs_read/write_data->lseg
  into the pNFS layer from whence they came.

- Let the pNFS layer manage the NFS_INO_PNFS_COMMIT bit.

From 9390f42546339cf111edd23c16d6cf74ca41974c Mon Sep 17 00:00:00 2001
From: Trond Myklebust <Trond.Myklebust@netapp.com>
Date: Fri, 16 Mar 2012 13:52:45 -0400
Subject: [PATCH 5480/6423] NFSv4.1: Fix a few issues in
 filelayout_commit_pagelist

- Fix a race in which NFS_I(inode)->commits_outstanding could potentially
  go to zero (triggering a call to nfs_commit_clear_lock()) before we're
  done sending out all the commit RPC calls.

- If nfs_commitdata_alloc fails, there is no reason why we shouldn't
  try to send off all the commits-to-ds.

- Simplify the error handling.

- Change pnfs_commit_list() to always return either
  PNFS_ATTEMPTED or PNFS_NOT_ATTEMPTED.

Subject: [PATCH 5481/6423] Try using machine credentials for RENEW calls

Using user credentials for RENEW calls will fail when the user
credentials have expired.

To avoid this, try using the machine credentials when making RENEW
calls. If no machine credentials have been set, fall back to using user
credentials as before.

Subject: [PATCH 5483/6423] PM / devfreq: add relation of recommended
 frequency.

The semantics of "target frequency" given to devfreq driver from
devfreq framework has always been interpretted as "at least" or GLB
(greatest lower bound). However, the framework might want the
device driver to limit its max frequency (LUB: least upper bound),
especially if it is given by thermal framework (it's too hot).

Thus, the target fuction should have another parameter to express
whether the framework wants GLB or LUB. And, the additional parameter,
"u32 flags", does it.

With the update, devfreq_recommended_opp() is also updated.

Subject: [PATCH 5484/6423] ASoC: fsl: p1022ds: tell the WM8776 codec driver
 that it's the master

The WM8776 codec driver requires the machine driver to set one of the
SND_SOC_DAIFMT_CBx_xxx values.  The P1022DS machine driver should be setting
SND_SOC_DAIFMT_CBM_CFM, but since that value was zero, no one noticed.

Commit 75d9ac46 ("ASoC: Allow DAI formats to be specified in the
dai_link"), however, changed the value of SND_SOC_DAIFMT_CBM_CFM from zero
to a non-zero value, which means that it now needs to be specifically set
by the machine driver.

We also set SND_SOC_DAIFMT_NB_NF, for the same reason.

This patch addresses a tcm_loop bug with transport_generic_allocate_tasks()
return checking in tcm_loop_submission_work() where other non zero return

This bug was introduced into target-pending/for-next-merge with the following
for-3.4 commit:

Subject: [PATCH 5487/6423] ib_srpt: Fix srpt_handle_cmd send_ioctx->ioctx_kref
 leak on exception

This patch addresses a bug in srpt_handle_cmd() failure handling where
send_ioctx->kref is being leaked with the local extra reference after init,
causing the expected kref_put() in srpt_handle_send_comp() to not be the final
call to invoke srpt_put_send_ioctx_kref() -> transport_generic_free_cmd() and
perform se_cmd descriptor memory release.

It also fixes a SCF_SCSI_RESERVATION_CONFLICT handling bug where this code
is incorrectly falling through to transport_handle_cdb_direct() after
invoking srpt_queue_status() to send SAM_STAT_RESERVATION_CONFLICT status.

Note this patch is for >= v3.3 mainline code, and current lio-core.git
code has already been converted to target_submit_cmd() + se_cmd->cmd_kref usage,
and internal ioctx->kref usage has been removed.  I'm including this patch
now into target-pending/for-next with a CC' for v3.3 stable.

The __netif_subqueue_stopped() just does the following:

        struct netdev_queue *txq = netdev_get_tx_queue(dev, queue_index);
        return netif_tx_queue_stopped(txq);

and since we already have the txq in scope, we can just call that
directly in this case.

Subject: [PATCH 5492/6423] firewire: ohci: simplify iso header pointer
 arithmetic

When storing the header data of completed iso packets, we effectively
treat the buffers as arrays of quadlets.  Actually declaring the
pointers as u32* avoids repetitive pointer arithmetic, removes the
unhelpfully named "i" variables, and thus makes the code clearer.

 code

In preparation for the following patches that add more flushing, move
the code for flushing accumulated header data into a common function.
The timestamp of the last completed packed is passed through the context
structure instead of a function parameter to allow accessing this value
later outside of the handle_i?_packet functions.

Subject: [PATCH 5494/6423] firewire: prevent dropping of completed iso packet
 header data

The buffer for the header data of completed iso packets has a fixed
size, so it is possible to configure a stream with a big interval
between interrupt packets or with big headers so that this buffer would
overflow.  Previously, ohci.c would drop any data that would not fit,
but this could make unsuspecting applications believe that fewer than
the actual number of packets have completed.

Instead of dropping data, add calls to flush_iso_completion() so that
there are as many events as needed to report all of the data.

Subject: [PATCH 5495/6423] firewire: allow explicit flushing of iso packet
 completions

Extend the kernel and userspace APIs to allow reporting all currently
completed isochronous packets, even if the next interrupt packet has not
yet been reached.  This is required to determine the status of the
packets at the end of a paused or stopped stream, and useful for more
precise synchronization of audio streams.

Commit b2a29b578d9c21b2e5c88020f830d3c42115c51d sets accidentally
supported delivery systems as DVB-T/T2 whilst it should be
DVB-S/S2. Due to that frontend cannot be used at all.

Subject: [PATCH 5521/6423] hwmon: (lm80) reset device if error occurred

If an error occurs while updating (e.g. because the chip was
disconnected) the device needs to be reinitialized in order
to get back to 11 bit temperature and set the fan divider.

Subject: [PATCH 5525/6423] hwmon: (max6650) Fix checkpatch issues

Fixed:
ERROR: do not use assignment in if condition
ERROR: open brace '{' following struct go on the same line
ERROR: spaces required around that '||' (ctx:VxV)
ERROR: switch and case should be at the same indent
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Date: Thu, 19 Jan 2012 11:02:17 -0800
Subject: [PATCH 5531/6423] hwmon: (f71805f) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: "foo* bar" should be "foo *bar"
ERROR: need consistent spacing around '|' (ctx:VxW)
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
WARNING: static const char * array should probably be static const char * const

Also modified multi-line comments to follow Documents/Codingstyle.

From: Axel Lin <axel.lin@gmail.com>
Date: Fri, 20 Jan 2012 15:38:18 +0800
Subject: [PATCH 5534/6423] hwmon: convert drivers/hwmon/* to use
 module_i2c_driver()

This patch converts the drivers in drivers/hwmon/* to use the
module_i2c_driver() macro which makes the code smaller and a bit simpler.

From 91efffe26a809bc6660b91e21264f48e501bfb46 Mon Sep 17 00:00:00 2001
From: Axel Lin <axel.lin@gmail.com>
Date: Fri, 20 Jan 2012 15:53:47 +0800
Subject: [PATCH 5535/6423] hwmon: convert drivers/hwmon/* to use
 module_spi_driver()

This patch converts the drivers in drivers/hwmon/* to use the
module_spi_driver() macro which makes the code smaller and a bit simpler.

From: Guenter Roeck <linux@roeck-us.net>
Date: Sat, 14 Jan 2012 13:26:08 -0800
Subject: [PATCH 5536/6423] hwmon: (ds1621) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: trailing whitespace
WARNING: labels should not be indented
WARNING: please, no spaces at the start of a line
WARNING: simple_strtol is obsolete, use kstrtol instead

Also modified multi-line comments to follow Documentation/CodingStyle.

From c6370dbe45278db0ebebc377c0a6143b7c488379 Mon Sep 17 00:00:00 2001
From: Guenter Roeck <linux@roeck-us.net>
Date: Sat, 14 Jan 2012 20:58:08 -0800
Subject: [PATCH 5556/6423] hwmon: (lm87) Fix checkpatch issues

Fixed:
ERROR: do not use assignment in if condition
ERROR: space required after that close brace '}'
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '<' (ctx:VxV)
ERROR: trailing statements should be on next line
WARNING: line over 80 characters
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed everywhere (code complexity):
ERROR: do not use assignment in if condition

As a side effect of the changes made, attribute set functions now return an
error if an attempt is made to write non-numeric values. Previously, such
writes were interpreted as writing 0.

From: Guenter Roeck <linux@roeck-us.net>
Date: Sat, 14 Jan 2012 21:25:54 -0800
Subject: [PATCH 5559/6423] hwmon: (lm93) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: else should follow close brace '}'
ERROR: space prohibited after that open parenthesis '('
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '<=' (ctx:VxV)
ERROR: spaces required around that '<' (ctx:VxV)
ERROR: spaces required around that '==' (ctx:VxV)
ERROR: spaces required around that '=' (ctx:VxV)
ERROR: spaces required around that ':' (ctx:VxW)
ERROR: trailing statements should be on next line
WARNING: braces {} are not necessary for any arm of this statement
WARNING: do not add new typedefs
WARNING: please, no space before tabs
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed (unknown impact):
WARNING: msleep < 20ms can sleep for up to 20ms

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '<=' (ctx:VxV)
ERROR: spaces required around that '==' (ctx:VxV)
ERROR: spaces required around that '>=' (ctx:VxV)
ERROR: trailing statements should be on next line
ERROR: trailing whitespace
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: static const char * array should probably be static const char * const

Modify multi-line comments to follow Documentation/CodingStyle.

Also: s/#define^I/#define /

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop

From ec1c3194179579df41be78551a0ca642f49e52ff Mon Sep 17 00:00:00 2001
From: Guenter Roeck <linux@roeck-us.net>
Date: Sun, 15 Jan 2012 09:29:36 -0800
Subject: [PATCH 5567/6423] hwmon: (w83791d) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: space prohibited after that open parenthesis '('
ERROR: space required after that ',' (ctx:VxV)
WARNING: braces {} are not necessary for single statement blocks
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed (false positive):
ERROR: Macros with complex values should be enclosed in parenthesis

Subject: [PATCH 5578/6423] hwmon: (abituguru) Fix checkpatch issues

Fixed:
ERROR: do not use assignment in if condition
ERROR: else should follow close brace '}'
ERROR: switch and case should be at the same indent
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed:
WARNING: msleep < 20ms can sleep for up to 20ms

ERROR: that open brace { should be on the previous line
WARNING: please, no space before tabs
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop

ERROR: spaces required around that '==' (ctx:VxV)
WARNING: please, no spaces at the start of a line
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop

Subject: [PATCH 5583/6423] hwmon: (dme1737) Fix checkpatch issues

Fixed:
WARNING: braces {} are not necessary for any arm of this statement
WARNING: braces {} are not necessary for single statement blocks
WARNING: simple_strtol is obsolete, use kstrtol instead

Modify multi-line comments to follow Documentation/CodingStyle.

Also: s/#define^I/#define /

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop

Subject: [PATCH 5593/6423] hwmon: (via686a) Fix checkpatch issues

Fixed:
ERROR: do not use assignment in if condition
ERROR: open brace '{' following function declarations go on the next line
ERROR: space prohibited before that close parenthesis ')'
ERROR: space required after that ',' (ctx:VxV)
ERROR: spaces required around that '==' (ctx:VxV)
ERROR: spaces required around that ':' (ctx:VxV)
ERROR: spaces required around that '?' (ctx:VxV)
ERROR: that open brace { should be on the previous line
WARNING: line over 80 characters
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed (false positive):
ERROR: Macros with multiple statements should be enclosed in a do - while loop

Date: Sun, 15 Jan 2012 06:52:33 -0800
Subject: [PATCH 5594/6423] hwmon: (vt1211) Fix checkpatch issues

Fixed:
ERROR: do not use assignment in if condition
ERROR: switch and case should be at the same indent
ERROR: trailing statements should be on next line
WARNING: braces {} are not necessary for single statement blocks
WARNING: simple_strtol is obsolete, use kstrtol instead

Modify multi-line comments to follow Documentation/CodingStyle.

Not fixed (false positive):
ERROR: Macros with complex values should be enclosed in parenthesis

Not all fixed (code complexity):
ERROR: do not use assignment in if condition

From: Guenter Roeck <linux@roeck-us.net>
Date: Sun, 15 Jan 2012 10:48:48 -0800
Subject: [PATCH 5597/6423] hwmon: (w83793) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: space required after that ',' (ctx:VxV)
WARNING: braces {} are not necessary for any arm of this statement
WARNING: braces {} are not necessary for single statement blocks
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead

Modify multi-line comments to follow Documentation/CodingStyle.

Also replaced "<constant> == <variable>" with "<variable> == <constant>".
Translation was done with the following coccinelle script to limit risk.

@@
identifier i;
constant C;
@@

<...
- C == i
+ i == C
...>

Not fixed (false positive):
ERROR: Macros with complex values should be enclosed in parenthesis

Subject: [PATCH 5598/6423] hwmon: (w83l786ng) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: do not use assignment in if condition
ERROR: space required after that ',' (ctx:VxV)
WARNING: braces {} are not necessary for single statement blocks
WARNING: please, no space before tabs
WARNING: please, no spaces at the start of a line
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
WARNING: space prohibited between function name and open parenthesis '('

Not fixed (false positive):
ERROR: Macros with complex values should be enclosed in parenthesis

From 27b9de3c4ae302c51d99187047e6ebebb21fd29b Mon Sep 17 00:00:00 2001
From: Guenter Roeck <linux@roeck-us.net>
Date: Sun, 15 Jan 2012 11:07:26 -0800
Subject: [PATCH 5599/6423] hwmon: (w83627hf) Fix checkpatch issues

Fixed:
WARNING: simple_strtol is obsolete, use kstrtol instead
WARNING: simple_strtoul is obsolete, use kstrtoul instead
ERROR: do not use assignment in if condition

Modify multi-line comments to follow Documentation/CodingStyle.

Other checkpatch issues not fixed to reduce number of conflicts with pending
rewrite as mfd driver.

Subject: [PATCH 5611/6423] hwmon: (lm70) Register hwmon device after creating
 attribute files, and remove it first

Register hwmon device as last operation in the probe function to ensure that all
attribute files exist when accessed from user applications. Otherwise, there
is a short time frame where the device is registered as hwmon device but
sysfs attributes do not yet exist. This could result in applications erroneously
not detecting attributes.

Subject: [PATCH 5615/6423] hwmon: (lm87) Get rid of macro-generated functions

Use SENSORS_DEVICE_ATTR instead of DEVICE_ATTR for most attributes,
so that the attribute number can be retrieved and it is no longer
necessary to generate functions using macros.

This shaves about 2 kB on the binary module size.

Subject: [PATCH 5617/6423] hwmon: (hwmon-vid) Add new entries to VRM model
 table

The VRM model table was missing several Intel CPUs, resulting in wrong VRM table
entries to be used for many recent CPUs. Update it. Also, use values from
struct cpuinfo_x86 to retrieve CPU model information instead of re-calculating
it locally.

Date: Tue, 24 Jan 2012 17:55:00 -0800
Subject: [PATCH 5618/6423] hwmon: (hwmon-vid) Fix checkpatch issues

Fixed:
ERROR: code indent should use tabs where possible
ERROR: space required before the open parenthesis '('
WARNING: EXPORT_SYMBOL(foo); should immediately follow its function/variable

Not fixed (url):
WARNING: line over 80 characters

Not fixed (false positive):
ERROR: Macros with complex values should be enclosed in parenthesis

From dd285ad7373bf5d21cceacb3b7a5eb8b72d37085 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5621/6423] hwmon: (pmbus) Simplify remove functions

Since devm_kzalloc() is now used to allocate driver memory, the client
driver remove function has no purpose other than to call pmbus_do_remove().
This means we can get rid of it by redefining pmbus_do_remove() to use the
same prototype, and pointing to it directly.

+This driver supports hardware montoring for Analog Devices ADM1075, ADM1275,
+and ADM1276 Hot-Swap Controller and Digital Power Monitor.
 
-ADM1275 and ADM1276 are hot-swap controllers that allow a circuit board to be
-removed from or inserted into a live backplane. They also feature current and

Subject: [PATCH 5633/6423] hwmon: (jc42) Remove unnecessary device IDs

We don't really use or need separate device IDs for the various JC42.4 compliant
chips, so remove them and just stick with jc42.

Also update a datasheet references for SE98A, STTS424, and STTS424E02.

Subject: [PATCH 5635/6423] md: allow re-add to failed arrays.

When an array is failed (some data inaccessible) then there is no
point attempting to add a spare as it could not possibly be recovered.

However that may be value in re-adding a recently removed device.
e.g. if there is a write-intent-bitmap and it is clear, then access
to the data could be restored by this action.

So don't reject a re-add to a failed array for RAID10 and RAID5 (the
only arrays  types that check for a failed array).

Subject: [PATCH 5636/6423] md: don't set md arrays to readonly on shutdown.

It seems that with recent kernel, writeback can still be happening
while shutdown is happening, and consequently data can be written
after the md reboot notifier switches all arrays to read-only.
This causes a BUG.

So don't switch them to read-only - just mark them clean and
set 'safemode' to '2' which mean that immediately after any
write the array will be switch back to 'clean'.

This could result in the shutdown happening when array is marked
dirty, thus forcing a resync on reboot.  However if you reboot
without performing a "sync" first, you get to keep both halves.

This is suitable for any stable kernel (though there might be some
conflicts with obvious fixes in earlier kernels).

 sysfs.

When commit 69e51b449d383e (md/bitmap:  separate out loading a bitmap...)
created bitmap_load, it missed calling it after bitmap_create when a
bitmap is created through the sysfs interface.
So if a bitmap is added this way, we don't allocate memory properly
and can crash.

This is suitable for any -stable release since 2.6.35.

Subject: [PATCH 5638/6423] md/raid1,raid10: avoid deadlock during
 resync/recovery.

If RAID1 or RAID10 is used under LVM or some other stacking
block device, it is possible to enter a deadlock during
resync or recovery.
This can happen if the upper level block device creates
two requests to the RAID1 or RAID10.  The first request gets
processed, blocks recovery and queue requests for underlying
requests in current->bio_list.  A resync request then starts
which will wait for those requests and block new IO.

But then the second request to the RAID1/10 will be attempted
and it cannot progress until the resync request completes,
which cannot progress until the underlying device requests complete,
which are on a queue behind that second request.

So allow that second request to proceed even though there is
a resync request about to start.

This is suitable for any -stable kernel.

Subject: [PATCH 5639/6423] md: tidy up rdev_for_each usage.

md.h has an 'rdev_for_each()' macro for iterating the rdevs in an
mddev.  However it uses the 'safe' version of list_for_each_entry,
and so requires the extra variable, but doesn't include 'safe' in the
name, which is useful documentation.

Consequently some places use this safe version without needing it, and
many use an explicity list_for_each entry.

So:
 - rename rdev_for_each to rdev_for_each_safe
 - create a new rdev_for_each which uses the plain
   list_for_each_entry,
 - use the 'safe' version only where needed, and convert all other
   list_for_each_entry calls to use rdev_for_each.

Subject: [PATCH 5640/6423] md: add proper merge_bvec handling to RAID0 and
 Linear.

These personalities currently set a max request size of one page
when any member device has a merge_bvec_fn because they don't
bother to call that function.

This causes extra works in splitting and combining requests.

So make the extra effort to call the merge_bvec_fn when it exists
so that we end up with larger requests out the bottom.

Subject: [PATCH 5641/6423] md/raid10: handle merge_bvec_fn in member devices.

Currently we don't honour merge_bvec_fn in member devices so if there
is one, we force all requests to be single-page at most.
This is not ideal.

So enhance the raid10 merge_bvec_fn to check that function in children
as well.

This introduces a small problem.  There is no locking around calls
the ->merge_bvec_fn and subsequent calls to ->make_request.  So a
device added between these could end up getting a request which
violates its merge_bvec_fn.

Currently the best we can do is synchronize_sched().  This will work
providing no preemption happens.  If there is preemption, we just
have to hope that new devices are largely consistent with old devices.

Subject: [PATCH 5642/6423] md/raid1: handle merge_bvec_fn in member devices.

Currently we don't honour merge_bvec_fn in member devices so if there
is one, we force all requests to be single-page at most.
This is not ideal.

So create a raid1 merge_bvec_fn to check that function in children
as well.

This introduces a small problem.  There is no locking around calls
the ->merge_bvec_fn and subsequent calls to ->make_request.  So a
device added between these could end up getting a request which
violates its merge_bvec_fn.

Currently the best we can do is synchronize_sched().  This will work
providing no preemption happens.  If there is is preemption, we just
have to hope that new devices are largely consistent with old devices.

Subject: [PATCH 5643/6423] md/raid10 - support resizing some RAID10 arrays.

'resizing' an array in this context means making use of extra
space that has become available in component devices, not adding new
devices.
It also includes shrinking the array to take up less space of
component devices.

This is not supported for array with a 'far' layout.  However
for 'near' and 'offset' layout arrays, adding and removing space at
the end of the devices is easy to support, and this patch provides
that support.

The use of a goto makes the control flow more obscure here.

So make it a normal:
  if (x) {
     Y;
  }

No functional change.

Subject: [PATCH 5647/6423] md/bitmap: remove some pointless locking.

There is nothing gained by holding a lock while we check if a pointer
is NULL or not.  If there could be a race, then it could become NULL
immediately after the unlock - but there is no race here.

So just remove the locking.

Subject: [PATCH 5648/6423] md/bitmap: remove unnecessary indirection when
 allocating.

These funcitons don't add anything useful except possibly the trace
points, and I don't think they are worth the extra indirection.
So remove them.

Subject: [PATCH 5649/6423] md/bitmap: discard CHUNK_BLOCK_SHIFT macro

Be redefining ->chunkshift as the shift from sectors to chunks rather
than bytes to chunks, we can just use "bitmap->chunkshift" which is
shorter than the macro call, and less indirect.

Subject: [PATCH 5650/6423] md: fix clearing of the 'changed' flags for the bad
 blocks list.

In super_1_sync (the first hunk) we need to clear 'changed' before
checking read_seqretry(), otherwise we might race with other code
adding a bad block and so won't retry later.

In md_update_sb (the second hunk), in the case where there is no
metadata (neither persistent nor external), we treat any bad blocks as
an error.  However we need to clear the 'changed' flag before calling
md_ack_all_badblocks, else it won't do anything.

This patch is suitable for -stable release 3.0 and later.

Subject: [PATCH 5653/6423] ixgbe: Update layout of ixgbe_ring structure to
 improve cache performance

This change makes it so that only the 2nd cache line in the ring structure
should see frequent updates.  The advantage to this is that it should
reduce the amount of cross CPU cache bouncing since only the 2nd cache line
will be changing between most network transactions.

Subject: [PATCH 5657/6423] ixgbe: Two minor fixes for RSS and FDIR set queues
 functions

This change fixes two minor issues. The first was the fact that we were
setting the return value to false twice in the set_rss_queues function.
The second is the fact that we should have been using "min_t(int," instead
of "min((int)" in set_fdir_queues.

Power domains that were off before hibernation shouldn't be turned on
during device restore, so prevent that from happening.

This change fixes up commit 65533bbf63b4f37723fdfedc73d0653958973323

    PM / Domains: Fix hibernation restore of devices, v2

that didn't include it by mistake.

Subject: [PATCH 5661/6423] amd64_edac: Fix missing csrows sysfs nodes

While initializing the array of csrow attribute instances, a few csrows
were uninitialized. This happened because the module only performed a
check for DRAM base ctl register0's and not DRAM base ctl register1's
chip select enable bit. There could be systems with DIMMs populated
on only single memory channel whereas the module also assumed that a
dual channel dimm had double the memory size of a single memory channel
instead of checking the memory on each channel.

This patch fixes these above issues.

Subject: [PATCH 5662/6423] x86: Fix section warnings

Fix the following section warnings :

WARNING: vmlinux.o(.text+0x49dbc): Section mismatch in reference
from the function acpi_map_cpu2node() to the variable
.cpuinit.data:__apicid_to_node The function acpi_map_cpu2node()
references the variable __cpuinitdata __apicid_to_node. This is
often because acpi_map_cpu2node lacks a __cpuinitdata
annotation or the annotation of __apicid_to_node is wrong.

WARNING: vmlinux.o(.text+0x49dc1): Section mismatch in reference
from the function acpi_map_cpu2node() to the function
.cpuinit.text:numa_set_node() The function acpi_map_cpu2node()
references the function __cpuinit numa_set_node(). This is often
because acpi_map_cpu2node lacks a __cpuinit  annotation or the
annotation of numa_set_node is wrong.

WARNING: vmlinux.o(.text+0x526e77): Section mismatch in
reference from the function prealloc_protection_domains() to the
function .init.text:alloc_passthrough_domain() The function
prealloc_protection_domains() references the function __init
alloc_passthrough_domain(). This is often because
prealloc_protection_domains lacks a __init  annotation or the annotation of alloc_passthrough_domain is wrong.

Subject: [PATCH 5664/6423] EDAC: Correct scrub rate API

The original scrub rate API definition states that if scrub rate
accessors are not implemented, a negative value (-1) should be written
to the sysfs file (/sys/devices/system/edac/mc/mc<N>/sdram_scrub_rate,
where N is the memory controller number on the system). This is
counter-intuitive and awkward at the very least because, when setting
the scrub rate, userspace has to write to sysfs and then read it back to
check error status of the operation.

As Tony notes, best it would be to not have the sdram_scrub_rate in
sysfs if scrub rate support is not implemented. It is too late about
that and a bunch of drivers on a bunch of arches would need to be
changed and tested which is not a trivial task ATM.

Instead, settle for the next best thing of returning -ENODEV when
implementation is missing and -EINVAL when there was an error
encountered while setting the scrub rate.

Subject: [PATCH 5665/6423] EDAC: Make pci_device_id tables __devinitconst.

These const tables are currently marked __devinitdata, but
Documentation/PCI/pci.txt says:

"o The ID table array should be marked __devinitconst; this is done
automatically if the table is declared with DEFINE_PCI_DEVICE_TABLE()."

So use DEFINE_PCI_DEVICE_TABLE(x).

Based on PaX and earlier work by Andi Kleen.

Subject: [PATCH 5672/6423] ASoC: pxa-ssp: atomically set stream active masks

PXA's SSP engine fails to take its current channel phase into account
when enabling a stream while the engine is already running. This
results in randomly swapped left/right channels on either the record
or the playback side, depending on which one was enabled first.

The following patch fixes this by factoring out the bit field
modifications in question to a separate function that pauses the
engine temporarily, modifies the bits and kicks it off again
afterwards. Appearantly, a transition of SSCR0_SSE syncs both
directions properly.

The patch has been rolled out to quite a number of devices over the
last weeks and seems to fix the issue reliably.

supported delivery systems as DVB-T/T2 whilst it should be
DVB-S/S2. Due to that frontend cannot be used at all.

Subject: [PATCH 5677/6423] [media] tea575x-tuner: update to latest V4L2
 framework requirements

The tea575x-tuner module has been updated to use the latest V4L2 framework
functionality. This also required changes in the drivers that rely on it.

The tea575x changes are:

- The drivers must provide a v4l2_device struct to the tea module.
- The radio_nr module parameter must be part of the actual radio driver,
  and not of the tea module.
- Changed the frequency range to the normal 76-108 MHz range instead of
  50-150.
- Add hardware frequency seek support.
- Fix broken rxsubchans/audmode handling.
- The application can now select between stereo and mono.
- Support polling for control events.
- Add V4L2 priority handling.

And radio-sf16fmr2.c now uses the isa bus kernel framework.

Subject: [PATCH 5678/6423] [media] tea575x: fix HW seek

Fix HW seek in TEA575x to work properly:
- a delay must be present after search start and before first register read
  or the seek does weird things
- when the search stops, the new frequency is not available immediately, we
  must wait until it appears in the register (fortunately, we can clear the
  frequency bits when starting the search as it starts at the frequency
  currently set, not from the value written)
- sometimes, seek remains on the current frequency (or moves only a little),
  so repeat it until it moves by at least 50 kHz

Subject: [PATCH 5685/6423] [media] v4l: Add custom compat_ioctl32 operation

Drivers implementing custom ioctls need to handle 32-bit/64-bit
compatibility themselves. Provide them with a way to do so.

To avoid circular module dependencies, merge the v4l2-compat-ioctl32
module into videodev. There is no point in keeping them separate, as the
v4l2_compat_ioctl32() function is required by videodev if CONFIG_COMPAT
is set anyway.

Subject: [PATCH 5691/6423] [media] STV0288 increase delay between carrier
 search

The current delay of 30uS is too short to recover any carrier.

In the lmedm04 driver delays were added to overcome carrier lock
problems. The typical delay was 30mS (2 x 15ms register write
0x2c and read 0x24).

Other drivers that use STV0288 don't appear to have any delay are
likely to have also suffered this problem.

Subject: [PATCH 5693/6423] [media] media, cx231xx: Fix double free on close

In cx231xx_v4l2_close() there are two calls to
cx231xx_release_resources(dev) followed by kfree(dev). That is a
problem since cx231xx_release_resources() already kfree()'s its
argument, so we end up doing a double free.

Easily resolved by just removing the redundant kfree() calls after the
calls to cx231xx_release_resources().

I also changed the 'dev = NULL' assignments (which are rather
pointless since 'dev' is about to go out of scope), to 'fh->dev = NULL'
since it looks to me that that is what was actually intended.
And I removed the 'dev = NULL' assignment at the end of
cx231xx_release_resources() since it is pointless.

Subject: [PATCH 5695/6423] [media] as102: add __packed attribute to structs
 defined inside packed structs

This patch fixes a regression in kernel 3.3 due to this patch:

http://patchwork.linuxtv.org/patch/8332/

That patch changes "#pragma pack(1)" with "__packed" attributes, but it is not
complete. In fact, in the as102 driver there are a lot of structs/unions
defined inside other structs/unions.
When the "__packed" attribute is applied only on the external struct, it will
not affect the internal struct definitions.
So the regression is fixed by specifiying the "__packed" attribute also on the
internal structs.

This patch should go into 3.3, as it fixes a regression introduced in the new
kernel version.

Subject: [PATCH 5696/6423] [media] as102: set optimal eLNA config values for
 each device

Ryley and me tested several eLNA configuration values with both a rooftop
and a portable antenna.

Ryley fuond out that the best value for his Elgato stick is indeed the current
default value 0xC0.

Instead, my stick is not capable of tuning VHF channels with 0xC0. With 0x80,
VHF works but the tuner sensitivity with the portable antenna is poor.
Instead, the value 0xA0 works with VHF and also gives good performance with
both the rooftop and the portable antenna.

So we concluded that devices built on the reference design work best with 0xA0,
while custom designs (Elgato, PCTV) seem to require 0xC0.

I also removed the unused parameter "minor" in struct as102_dev_t.

Subject: [PATCH 5699/6423] [media] dib9000: implement error handling for
 DibAcquireLock

DibAcquireLock() is implemented as mutex_lock_interruptible()
but the driver does not handle unsuccessful locking.
As a result it may lead to unlock of an unheld mutex.

 int in CDRXD()

In CDRXD(), Negative number is assigned to unsigned variable
'state->noise_cal.tdCal2.

Members of 'SNoiseCal' should be 'signed short'.

Subject: [PATCH 5702/6423] [media] m88rs2000 1.12 v2 DVB-S frontend and tuner
 module

Support for m88rs2000 chip used in lmedm04 driver.

Note there are still lock problems.

Slow channel change due to the large block of registers sent in set_frontend.

Version 2 differences.
Front end is completely shut down when in sleep mode. This allow user to regain
control of device.
Kaffeine scan problem solved by removing register calls from get_frontend.
Kaffeine seems to call get_frontend when updating signal data. This can happen
in the middle of a tune stalling the driver.
Change calculations to those in the DS3000 driver.

Subject: [PATCH 5703/6423] [media] m88rs2000: Don't fill info.type

This field is handled internally by the DVB core, with uses the
selected delivery system to fill it, when a DVBv3 call is
handled. So, drivers should not touch on it.

Subject: [PATCH 5704/6423] [media] lmedm04 ver 1.99 support for m88rs2000 v2

Support for m88rs2000 module.

The driver also attempts to overcome occasional lock problems.

Call backs are now used for read_status, signal level and SNR.

Subject: [PATCH 5709/6423] SUNRPC: We must not use list_for_each_entry_safe()
 in rpc_wake_up()

The problem is that for the case of priority queues, we
have to assume that __rpc_remove_wait_queue_priority will move new
elements from the tk_wait.links lists into the queue->tasks[] list.
We therefore cannot use list_for_each_entry_safe() on queue->tasks[],
since that will skip these new tasks that __rpc_remove_wait_queue_priority
is adding.

Without this fix, rpc_wake_up and rpc_wake_up_status will both fail
to wake up all functions on priority wait queues, which can result
in some nasty hangs.

Subject: [PATCH 5716/6423] [media] gpio-ir-recv: a couple signedness bugs

There are couple places where we check unsigned values for negative.  I
changed ->gpin_nr to signed because in gpio_ir_recv_probe() we do:
        if (pdata->gpio_nr < 0)
                return -EINVAL;
I also change gval to a signed int in gpio_ir_recv_irq() because that's
the type that gpio_get_value_cansleep() returns and we test for negative
returns.

Subject: [PATCH 5718/6423] [media] dvb: earth-pt1: stop polling data when no
 one accesses the device

The driver started a kthread to poll the DMA buffers soon after probing,
which relsuleted in 1000/sec sleeps and wakeups of the thread doing nothing
useful until someone started feeding.
This patch changes the creation and destruction of the kthread depending on the number of users.

Subject: [PATCH 5720/6423] [media] dvb: earth-pt1: decrease the too large DMA
 buffer size

Current default value of "nr_tables" option corresponds to the DMA
buffer of about 10 to 48 seconds long, which is obviously too much.

Subject: [PATCH 5724/6423] ASoC: wm8994: Provide VMID mode control and fix
 default sequence

The optimal management of VMID depends on a number of factors which vary
dynamically at runtime, for example the connection to a system docking
station. In some circumstances it is desirable to keep VMID enabled all
the time, in others it is desirable to aggressively power it up and down.

Provide a callback allowing machine driver to configure either the normal
power up/down mode (WM8994_VMID_MODE_NORMAL) or to maintain VMID even
when idle (WM8994_VMID_MODE_FORCE). This callback, wm8994_vmid_mode(),
should be called with the CODEC lock.

Subject: [PATCH 5725/6423] ixgbe: Correct flag values set by
 ixgbe_fix_features

This patch replaces the variable name data with the variable name features
for ixgbe_fix_features and ixgbe_set_features.  This helps to make some
issues more obvious such as the fact that we were disabling Rx VLAN tag
stripping when we should have been forcing it to be enabled when DCB is
enabled.

In addition there was deprecated code present that was disabling the LRO
flag if we had the itr value set too low.  I have updated this logic so
that we will now allow the LRO flag to be set, but will not enable RSC
until the rx-usecs value is high enough to allow enough time for Rx packet
coalescing.

Subject: [PATCH 5731/6423] bnx2x: revised driver prints

We've revised driver prints, changing the mask of existing prints
to allow better control over the debug messages, added prints to
error scenarios, removed unnecessary prints and corrected some spelling.
Please note that this patch contains lines with over 80 characters,
as string messages were kept in a single line.

Subject: [PATCH 5734/6423] bnx2x: changed initial dcb configuration

The changes were mostly made to enable back-to-back data flow with dcb.
Other changes were simply deemed as a better 'clean' initial configuration.

Subject: [PATCH 5736/6423] bnx2x: changed iscsi/fcoe mac init and macros

This includes changes in macros to better distinguish between the two
protocols, and slightly changed the way their macs are set.
Notice this file contains string print lines with more than 80 characters,
as to not break prints.

Subject: [PATCH 5737/6423] bnx2x: consistent statistics for old FW

Previously applied patch making the bnx2x statistics consistent
did not apply to old FWs. This remedies it, extending the consistent
behaviour to all drivers.

Subject: [PATCH 5739/6423] tcp: introduce tcp_data_queue_ofo
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Split tcp_data_queue() in two parts for better readability.

tcp_data_queue_ofo() is responsible for queueing incoming skb into out
of order queue.

Change code layout so that the skb_set_owner_r() is performed only if
skb is not dropped.

This is a preliminary patch before "reduce out_of_order memory use"
following patch.

Subject: [PATCH 5740/6423] tcp: reduce out_of_order memory use
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With increasing receive window sizes, but speed of light not improved
that much, out of order queue can contain a huge number of skbs, waiting
to be moved to receive_queue when missing packets can fill the holes.

Some devices happen to use fat skbs (truesize of 4096 + sizeof(struct
sk_buff)) to store regular (MTU <= 1500) frames. This makes highly
probable sk_rmem_alloc hits sk_rcvbuf limit, which can be 4Mbytes in
many cases.

When limit is hit, tcp stack calls tcp_collapse_ofo_queue(), a true
latency killer and cpu cache blower.

Doing the coalescing attempt each time we add a frame in ofo queue
permits to keep memory use tight and in many cases avoid the
tcp_collapse() thing later.

Tested on various wireless setups (b43, ath9k, ...) known to use big skb
truesize, this patch removed the "packets collapsed in receive queue due
to low socket buffer" I had before.

This also reduced average memory used by tcp sockets.

With help from Neal Cardwell.

Subject: [PATCH 5745/6423] ixgbe: fix namespace issues when FCoE/DCB is not
 enabled

Resolve namespace issues when FCoE or DCB is not enabled.
The issue is with certain configurations we end up with namespace
problems. A simple example:

ixgbe_main.c
 - defines func A()
 - uses func A()

ixgbe_fcoe.c
 - uses func A()

ixgbe.h
 - has prototype for func A()

For default (FCoE included) all is good.  But when it isn't the namespace
checker complains about how func A() could be static.

To resolve this, created a ixgbe_lib file to contain functions used
by DCB/FCoE and their helper functions so that they are always in
namespace whether or not DCB/FCoE is enabled.

Subject: [PATCH 5746/6423] net/hyperv: Fix the code handling tx busy

Instead of dropping the packet, we keep the skb buffer, and return
NETDEV_TX_BUSY to let upper layer retry send. This will not cause
endless loop, because the host is taking data away from ring buffer,
and we have called the stop_queue before returning NETDEV_TX_BUSY.

The stop_queue was called in the function netvsc_send() in file
netvsc.c, then it returns to rndis_filter_send(), which returns to
netvsc_start_xmit() in file netvsc_drv.c. So the NETDEV_TX_BUSY is
indeed returned AFTER queue is stopped.

Subject: [PATCH 5747/6423] ixgbe: Fix issues with SR-IOV loopback when flow
 control is disabled

This patch allows us to avoid a Tx hang when SR-IOV is enabled.  This hang
can be triggered by sending small packets at a rate that was triggering Rx
missed errors from the adapter while the internal Tx switch and at least
one VF are enabled.

This was all due to the fact that under heavy stress the Rx FIFO never
drained below the flow control high water mark.  This resulted in the Tx
FIFO being head of line blocked due to the fact that it relies on the flow
control high water mark to determine when it is acceptable for the Tx to
place a packet in the Rx FIFO.

The resolution for this is to set the FCRTH value to the RXPBSIZE - 32 so
that even if the ring is almost completely full we can still place Tx
packets on the Rx ring and drop incoming Rx traffic if we do not have
sufficient space available in the Rx FIFO.

This is related to fixing the bug of dropping FCoE frames when disabling tx ip
checksum by 'ethtool -K ethx tx off'. The FCoE protocol stack driver would
use CHECKSUM_UNNECESSARY on tx path instead of CHECKSUM_PARTIAL (as indicated in
the 2/2 of this series). To do so, netif_needs_gso() has to be changed here to
not do gso for both CHECKSUM_PARTIAL and CHECKSUM_UNNECESSARY.

 CHECKSUM_PARTIAL on tx

Fix a bug when using 'ethtool -K ethx tx off' to turn off tx ip checksum,
FCoE CRC offload should not be impacte. The skb_checksum_help() is needed
only if it's not FCoE traffic for ip checksum, regardless of ethtool toggling
the tx ip checksum on or off. Instead of using CHECKSUM_PARTIAL, we will
use CHECKSUM_UNNECESSARY as a proper indication to avoid sw ip checksum
on FCoE frames.

Matt Evans spotted that x86 bpf_jit was incorrectly handling negative
constant offsets in BPF_S_LDX_B_MSH instruction.

We need to abort JIT compilation like we do in common_load so that
filter uses the interpreter code and can call __load_pointer()

Subject: [PATCH 5755/6423] [media] v4l: Add driver for Micron MT9M032 camera
 sensor

The MT9M032 is a parallel 1.6MP sensor from Micron controlled through I2C.

The driver creates a V4L2 subdevice. It currently supports cropping, gain,
exposure and v/h flipping controls in monochrome mode with an
external pixel clock.

[Lots of clean up, fixes and enhancements]

Subject: [PATCH 5756/6423] [media] V4L/v4l2-dev: Make 'videodev_init' as a
 subsys initcall

As the V4L2 based UVC webcam gadget (g_webcam) expects the
'videodev' to present when the 'webcam_bind' routine is called,
so 'videodev' should be available as early as possible.

Now, when 'g_webcam' is built as a module (i.e. not a part of
kernel) the late availability of 'videodev' is OK, but if
'g_webcam' is built statically as a part of the kernel,
the kernel crashes (a sample crash dump using Designware 2.0 UDC
is provided below).

To solve the same, this patch makes 'videodev_init' as a subsys initcall.

Subject: [PATCH 5757/6423] fs_enet: Add MPC5125 FEC support and PHY interface
 selection

Add compatible string for MPC5125 FEC. The FEC on MPC5125 additionally
supports RMII PHY interface. Configure controller/PHY interface type
according to the optional phy-connection-type property in the ethernet
node. This property should be either "rmii" or "mii".

Subject: [PATCH 5758/6423] bonding: send igmp report for its master

Liang Zheng(lzheng@redhat.com) found that in the following topo,
bonding does not send igmp report when we trigger a fail-over of bonding.

eth0--
      |-- bond0 -- br0
eth1--

modprobe bonding mode=1 miimon=100 resend_igmp=10
ifconfig bond0 up
ifenslave bond0 eth0 eth1

brctl addbr br0
ifconfig br0 192.168.100.2/24 up
brctl addif br0 bond0

Add 192.168.100.2(br0) into a multicast group, like 224.10.10.10,
then trigger a fali-over in bonding.
You can see that parameter "resend_igmp" does not work.

The reason is that when we add br0 into a multicast group,
it does not propagate multicast knowledge down to its ports.

If we choose to propagate multicast knowledge down to all ports for bridge,
then we have to track every change that is done to bridge, and keep a backup
for all ports. It is hard to track, I think.

Instead I choose to modify bonding to send igmp report for its master.

Changelog:
V2: correct comments
V3: move this check into bond_resend_igmp_join_requests()
V4: only send igmp reports if bond is enslaved to a bridge

Subject: [PATCH 5759/6423] mlx4_core: fix race on comm channel

Prevent race condition between commands on comm channel.
Happened while unloading the driver when switching from
event to polling mode. VF got completion on the last command
before switching to polling mode, but toggle was not changed.
After the fix - VF will not write the next command before
toggle is updated.

Subject: [PATCH 5762/6423] netdev: driver: ethernet: Add TI CPSW driver

This patch adds support for TI's CPSW driver.

The three port switch gigabit ethernet subsystem provides ethernet packet
communication and can be configured as an ethernet switch. Supports
10/100/1000 Mbps.

From ff732d281b29ad7898c1193843ebe6a37d426e36 Mon Sep 17 00:00:00 2001
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Date: Mon, 12 Mar 2012 10:02:47 -0300
Subject: [PATCH 5763/6423] [media] media: Initialize the media core with
 subsys_initcall()

Media-related drivers living outside drivers/media/ (such as the UVC
gadget driver in drivers/usb/gadget/) rely on the media core being
initialized before they're probed. As drivers/usb/ is linked before
drivers/media/, this is currently not the case and will lead to crashes
if the drivers are not compiled as modules.

Register media_devnode_init() as a subsys_initcall() instead of
module_init() to fix this.

Subject: [PATCH 5765/6423] [media] au8522: bug-fix: enable modulation AFTER
 tune (instead of before tuning)

The au8522 driver programs the tuner after programming the demodulator,
but the tuner should be programmed first. This patch fixes this behavior.

EDIT: Apparantly Devin created a similar patch some time ago, but hasn't
submitted it for merge.  I never saw his patch, but I thank him anyhow
for his efforts.  In addition, Devin pointed out a flaw in my patch:

This newly generated patch takes Devin's comments into account.

Subject: [PATCH 5768/6423] [media] dib0700: Drop useless check when remote key

struct dvb_usb_device *d can never be NULL so don't waste time
checking for this.

Rationale: the urb's context is set when usb_fill_bulk_urb() is called
in dib0700_rc_setup(), and never changes after that. d is dereferenced
unconditionally in dib0700_rc_setup() so it can't be NULL or the
driver would crash right away.

Subject: [PATCH 5770/6423] [media] af9015: fix i2c failures for dual-tuner
 devices

The i2c failures were caused by enabling both i2c gates
at the same time while putting the tuners asleep.

This patch removes the init() and sleep() callbacks from the tuner,
to prevent frontend.c from calling
  i2c_gate_ctrl
  tuner init / sleep
  i2c_gate_ctrl
without holding the lock.
tuner init() and sleep() are instead called in frontend init() and
sleep().

Subject: [PATCH 5772/6423] [media] m88rs2000 ver 1.13 Correct deseqc and tuner
 gain functions

Remove incorrect SEC_MINI_B settings-TODO complete this section.

Correct break and remove return -EINVAL within set tone. It appears
there is a bug that occasionally something other than ON/OFF is
sent stalling the driver. Just continue and write back registers.

Set register b2 in setup. This is the set voltage pin which
isn't used in lmedm04 driver but it is always set to 0x1.

Correct the if statements in set_tuner_rf.

Subject: [PATCH 5773/6423] fbdev: da8xx:: fix reporting of the display timing
 info

Timing info is not properly reported by the driver, e.g.:

$ fbset -i
mode "480x272-35"
    # D: 7.895 MHz, H: 12.165 kHz, V: 35.158 Hz
    geometry 480 272 480 544 16
    timings 126666 64 64 32 32 41 10

According to the timing values defined for LK043T1DG01 display
it should be reported as:

mode "480x272-53"
    # D: 7.895 MHz, H: 15.038 kHz, V: 52.579 Hz
    geometry 480 272 480 544 16
    timings 126666 2 2 2 2 41 10

Initialize additional fb_var_screeninfo fields so fix this problem.

Subject: [PATCH 5774/6423] fbdev: da8xx: add support for SP10Q010 display

Add timing data for Hitachi SP10Q010 display and allow configuration
of the 4bpp palette. For 4bpp framebuffer enable reversed order of
pixels in a byte. This requires defining FB_CFB_REV_PIXELS_IN_BYTE
and additionally setting var.nonstd to the value FB_NONSTD_REV_PIX_IN_B.
Note that it is not enough to set da8xx_fb_var.nonstd to this value
statically, since FBIOPUT_VSCREENINFO ioctl might pass var struct with
.nonstd field set to zero or another value. Therefore this setting must
be adjusted in fb_check_var() according to the requested bpp value.

Call sequence:
tomoyo_write_domain() --> tomoyo_delete_domain()

In 'tomoyo_delete_domain', return -EINTR if locking attempt is
interrupted by signal.

At present it returns success to its caller 'tomoyo_write_domain()'
even though domain is not deleted. 'tomoyo_write_domain()' assumes
domain is deleted and returns success to its caller. This is wrong behaviour.

'tomoyo_write_domain' should return error from tomoyo_delete_domain() to its
caller.

Subject: [PATCH 5777/6423] [media] rc: Pospone ir raw decoders loading until

This changes rc_core to not load the IR decoders at load time,
postponing it to load only if a RC_DRIVER_IR_RAW device is
registered via rc_register_device.
We use a static boolean variable, to ensure decoders modules
are only loaded once.
Tested with rc-loopback device only.

soc_camera_power_on() calls client's .s_power(1) method, which can try to
access the client hardware. This, however, is typically only possible,
after calling host's .add() method, because that's where the host driver
usually turns the master clock on.

Newer CEU versions, e.g., the one, used on sh7372, support image sizes
larger than 2560x1920. Retrieve maximum sizes from platform properties.

The controller stop/restart logic could possibly restart DMA after the
driver things things have stopped, with suitably ugly results.  Make sure
that we only restart the hardware if we're supposed to be streaming.

The marvell cam driver retained just enough of the owner-tracking logic
from cafe_ccic to be broken; it could, conceivably, cause the driver to
release DMA memory while the controller is still active.  Simply remove the
remaining pieces and ensure that the controller is stopped before we free
things.

Experience shows that, on the Armada platform, it can take as much as 120ms
for the DMA engine to actually shut down after it has been told to.  So a
40ms timeout is not adequate; use 150ms instead.  Also make sure we don't
leave the DMA_ACTIVE flag set once things are down.

Subject: [PATCH 5785/6423] [media] marvell-cam: fix the green screen of death

I had learned through hard experience that dinking around with the DMA
descriptors while the C1_DESC_ENA enable bit was set is a recipe for all
kinds of truly malicious behavior on the hardware's part, regardless of
whether the DMA engine is actually operating at the time.  That
notwithstanding, the driver did so dink, resulting in "green frame"
captures and the death of the system in random, spectacular ways.

Move the tweaking of C1_DESC_ENA to the same function that sets the
descriptor so we know that we'll never try to set a descriptor while that
bit is set.

it still tells us that any or all of frames 1-3 are done at each completion
interrupt.  Avoid the creation of junk frames by being sure to only
"complete" one on each interrupt.

Subject: [PATCH 5787/6423] [media] mmp-camera: Don't power up the sensor on
 resume

We still need to power up the controller to avoid unsightly self-immolation
should something try to access its registers, but the sensor can stay
powered down unless the camera was actually operating at suspend time.
This gets rid of the camera LED flash on resume, fixing OLPC bug #11644.

Empia EM2874B
Micronas DRX 3913KA2
NXP TDA18271HDC2

Only DVB-C supported currently since missing firmware.

in order to support DVB-T mode.

Subject: [PATCH 5792/6423] [media] pvrusb2: fix 7MHz & 8MHz DVB-T tuner
 support for HVR1900 rev D1F5

The D1F5 revision of the WinTV HVR-1900 uses a tda18271c2 tuner
instead of a tda18271c1 tuner as used in revision D1E9. To
account for this, we must hardcode the frontend configuration
to use the same IF frequency configuration for both revisions
of the device.

6MHz DVB-T is unaffected by this issue, as the recommended
IF Frequency configuration for 6MHz DVB-T is the same on both
c1 and c2 revisions of the tda18271 tuner.

Subject: [PATCH 5800/6423] [media] gspca - sn9c20x: Add the JPEG compression
 quality control
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The JPEG compression quality was hardcoded to 95%. This value was too big,
raising often buffer overflows.
This quality is now 80% by default and is settable.

Subject: [PATCH 5803/6423] [media] gspca - sn9c20x: Add automatic JPEG
 compression mechanism
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The JPEG compression may be adjusted from the packet fill ratio and from
the flag 'USB FIFO full' returned in each frame.
The code is adapted from the one in gspca sonixj and uses a workqueue.

Subject: [PATCH 5806/6423] [media] -EINVAL -> -ENOTTY

I found one more place where -EINVAL is used instead of -ENOTTY:

Note that drivers/media/dvb/dvb-core/dvbdev.c has the same code, but as far as
I can tell DVB is still using -EINVAL for unknown ioctls so I didn't change
that.

Subject: [PATCH 5807/6423] [media] em28xx: support for 2013:0251 PCTV
 QuatroStick nano (520e)

Hardware is based of:
Empia EM2884
Micronas DRX 3926K
NXP TDA18271HDC2

... + analog parts.
Analog is not supported currently. Only DVB-T and DVB-C.

There seems to be still	problems for locking DVB-C channels which have
strong signal. Attenuator helps. I think it is demodulator IF/RF AGC
issue. Lets fix it later. Patches are welcome.

Subject: [PATCH 5808/6423] [media] em28xx: support for 2304:0242 PCTV
 QuatroStick (510e)

It is mostly copy/paste of the 520e code with setting GPIO7 removed
(no LED light).

I've worked on just released vanilla linux-3.3.0 kernel, so there may
be 1/2 lines offset to the internal working source, but most of the
code should apply cleanly.

I was able to get the DVB-C working (tuned and watched TV). Haven't
tested DVB-T (no signal atm).

Special thanks to everybody who worked on the code and to Antti
Palosaari and Devin Heitmueller who provided essential support on irc.

Hardware is based of:
Empia EM2884
Micronas DRX 3926K
NXP TDA18271HDC2
AVF4910 (not used atm)

Subject: [PATCH 5809/6423] [media] stb0899: fix the limits for signal strength
 values

stb0899: fix the limits for signal strength values

stb0899_read_signal_strength() adds an offset to the result of the table lookup.
That offset must correspond to the lowest value in the lookup table, to make sure
the result doesn't get below 0, which would mean a "very high" value since the
parameter is unsigned.
'strength' and 'snr' need to be initialized to 0 to make sure they have a
defined result in case there is no "internal->lock".

 evergreen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

There are also two fixes:
- In DRAW_INDEX_2, we read idx_value, but should have read idx+1.
- When correcting SQ_VTX_CONSTANT_WORD1_0.SIZE, we should subtract
  the offset.

Subject: [PATCH 5823/6423] drivers/gpu/drm/radeon/radeon_cs.c: eliminate
 possible double free

The function radeon_cs_parser_init is only called from two places, in
drivers/gpu/drm/radeon/radeon_cs.c and drivers/gpu/drm/radeon/r600_cs.c.
In each case, if the call fails another function is called that frees all
of the kdata and dpage information in the chunks array.  So this
information should not be freed in radeon_cs_parser_init as well.

 kfree

Most of the error handling code in this function frees the buffers
kcmd_addr, kvb_addr, and kbox_addr allocated at the beginning of this
function.  These two branches are changed to do the same.

Subject: [PATCH 5828/6423] drm/radeon/kms: reduce probe latency on digital
 connectors

On a system with one HDMI and one VGA connector the latter
causes output polling to run every ten seconds. This causes
full EDID re-fetch on every poll and approx. 100ms rendering
stalls are experienced by full screen page-flipping applications.
Optimisation is to trust HPD sense on R600+ ASICs and to skip
doing these expensive probes unless HPD sense has changed.

Fixes:
https://bugs.freedesktop.org/show_bug.cgi?id=47007

agd5f: fix patch and message formatting.

Subject: [PATCH 5834/6423] ipv6: fix incorrent ipv6 ipsec packet fragment

Since commit 299b0767(ipv6: Fix IPsec slowpath fragmentation problem)
In func ip6_append_data,after call skb_put(skb, fraglen + dst_exthdrlen)
the skb->len contains dst_exthdrlen,and we don't reduce dst_exthdrlen at last
This will make fraggap>0 in next "while cycle",and cause the size of skb incorrent

Fix this by reserve headroom for dst_exthdrlen.

Subject: [PATCH 5835/6423] drm/exynos: add HDMI version 1.4 support

Later Exynos series from Exynos4X12 support HDMI version 1.4. We will
distinguish to use which version via platform data. This patch supports
only default features of HDMI version 1.4(The 3D, sound and etc don't
support yet)

From 2b35892e9da672df40ce890bffc4f9f6119c57e0 Mon Sep 17 00:00:00 2001
From: Inki Dae <inki.dae@samsung.com>
Date: Fri, 16 Mar 2012 18:47:05 +0900
Subject: [PATCH 5837/6423] drm/exynos: update gem and buffer framework.

with this patch, we can allocate physically continuous or non-continuous
memory and also it creates scatterlist for iommu support so allocated
memory region can be mapped to iommu page table using scatterlist.

From f0b1bda725c1c49620d2e7ae7405a247098cdb8e Mon Sep 17 00:00:00 2001
From: Inki Dae <inki.dae@samsung.com>
Date: Fri, 16 Mar 2012 18:47:06 +0900
Subject: [PATCH 5838/6423] drm/exynos: added new funtion to get/put dma
 address.

this function would be used for drm based 2d acceleration driver
to get/put dma address through gem handle.
when exynos_drm_get_dma_address is called reference count of
gem object would be increased not to be released by gem close and
when exynos_drm_put_dma_address is called the reference count of
this gem object would be decreased to be released.

 closed

We should release pending pageflip events when closed. If not, they will
be dangling events.

Subject: [PATCH 5840/6423] drm/exynos: remove module of exynos drm subdrv

The exynos drm driver has several subdrv. They each can be module but it
causes unfixed probe order of exynodr drm driver and each subdrv. It
also needs some weird codes such as exynos_drm_fbdev_reinit and
exynos_drm_mode_group_reinit. This patch can remove weird codes and
clear codes through we doesn't modularity each subdrv.

Also this removes unnecessary codes related module.

Subject: [PATCH 5846/6423] drm: allow loading an EDID as firmware to override
 broken monitor

Broken monitors and/or broken graphic boards may send erroneous or no
EDID data. This also applies to broken KVM devices that are unable to
correctly forward the EDID data of the connected monitor but invent
their own fantasy data.

This patch allows to specify an EDID data set to be used instead of
probing the monitor for it. It contains built-in data sets of frequently
used screen resolutions. In addition, a particular EDID data set may be
provided in the /lib/firmware directory and loaded via the firmware
interface. The name is passed to the kernel as module parameter of the
drm_kms_helper module either when loaded
  options drm_kms_helper edid_firmware=edid/1280x1024.bin
or as kernel commandline parameter
  drm_kms_helper.edid_firmware=edid/1280x1024.bin

It is also possible to restrict the usage of a specified EDID data set
to a particular connector. This is done by prepending the name of the
connector to the name of the EDID data set using the syntax
  edid_firmware=[<connector>:]<edid>
such as, for example,
  edid_firmware=DVI-I-1:edid/1920x1080.bin
in which case no other connector will be affected.

The built-in data sets are
Resolution    Name
--------------------------------
1024x768      edid/1024x768.bin
1280x1024     edid/1280x1024.bin
1680x1050     edid/1680x1050.bin
1920x1080     edid/1920x1080.bin

They are ignored, if a file with the same name is available in the
/lib/firmware directory.

The built-in EDID data sets are based on standard timings that may not
apply to a particular monitor and even crash it. Ideally, EDID data of
the connected monitor should be used. They may be obtained through the
drm/cardX/cardX-<connector>/edid entry in the /sys/devices PCI directory
of a correctly working graphics adapter.

It is even possible to specify the name of an EDID data set on-the-fly
via the /sys/module interface, e.g.
echo edid/myedid.bin >/sys/module/drm_kms_helper/parameters/edid_firmware
The new screen mode is considered when the related kernel function is
called for the first time after the change. Such calls are made when the
X server is started or when the display settings dialog is opened in an
already running X server.

+In the good old days when graphics parameters were configured explicitly
+in a file called xorg.conf, even broken hardware could be managed.
+
+Today, with the advent of Kernel Mode Setting, a graphics board is
+either correctly working because all components follow the standards -
+or the computer is unusable, because the screen remains dark after
+booting or it displays the wrong area. Cases when this happens are:
+- The graphics board does not recognize the monitor.
+- The graphics board is unable to detect any EDID data.
+- The graphics board incorrectly forwards EDID data to the driver.
+- The monitor sends no or bogus EDID data.
+- A KVM sends its own EDID data instead of querying the connected monitor.
+Adding the kernel parameter "nomodeset" helps in most cases, but causes
+restrictions later on.
+
+As a remedy for such situations, the kernel configuration item
+CONFIG_DRM_LOAD_EDID_FIRMWARE was introduced. It allows to provide an
+individually prepared or corrected EDID data set in the /lib/firmware
+directory from where it is loaded via the firmware interface. The code
+(see drivers/gpu/drm/drm_edid_load.c) contains built-in data sets for
+commonly used screen resolutions (1024x768, 1280x1024, 1680x1050,
+1920x1080) as binary blobs, but the kernel source tree does not contain
+code to create these data. In order to elucidate the origin of the
+built-in binary EDID blobs and to facilitate the creation of individual
+data for a specific misbehaving monitor, commented sources and a
+Makefile environment are given here.
+
+To create binary EDID and C source code files from the existing data
+material, simply type "make".
+
+If you want to create your own EDID file, copy the file 1024x768.S and
+replace the settings with your own data. The CRC value in the last line
+  #define CRC 0x55
+is a bit tricky. After a first version of the binary data set is
+created, it must be be checked with the "edid-decode" utility which will
+most probably complain about a wrong CRC. Fortunately, the utility also
+displays the correct CRC which must then be inserted into the source
+file. After the make procedure is repeated, the EDID data set is ready
+to be used.

Subject: [PATCH 5849/6423] HID: multitouch: add PID for Fructel product

Adds multitouch support for the Gametel Android game controller.

The multitouch events are emulated by the Gametel device. Each physical button
is configured to generate a MT event on a specific coordinate. This seems to be
the only way for us to support Android games that doesn't support HID gamepads.
It is possible to inject MT events at Android level, but this requires root on
the phone.

Subject: [PATCH 5850/6423] hwmon: (sch56xx) Add support for the integrated
 watchdog (v2)

Add support for the watchdog integrated into the SMSC SCH5627 and
SCH5636 superio-s. Since the watchdog is part of the hwmon logical device
and thus shares ioports with it, the watchdog driver is integrated into the
existing hwmon drivers for these.

Note that this version of the watchdog support for sch56xx superio-s
implements the watchdog chardev interface itself, rather then relying on
the recently added watchdog core / watchdog_dev. This is done because
currently some needed functionality is missing from watchdog_dev, as soon
as this functionality is added (which is being discussed on the
linux-watchdog mailinglist), I'll convert this driver over to using
watchdog_dev.

Subject: [PATCH 5851/6423] highmem: mark k[un]map_atomic() with two arguments
 as deprecated
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For backward compatibility, we still keep the deprecated form,
and will warn the users if they still use the deprecated one, like this:

drivers/block/drbd/drbd_bitmap.c: In function ‘bm_page_io_async’:
drivers/block/drbd/drbd_bitmap.c:973:3: warning: ‘kmap_atomic_deprecated’ is deprecated (declared at /home/wangcong/linux-2.6/include/linux/highmem.h:124)
drivers/block/drbd/drbd_bitmap.c:977:3: warning: ‘kunmap_atomic_deprecated’ is deprecated (declared at /home/wangcong/linux-2.6/include/linux/highmem.h:144)

Thanks to Nick Bowler for the cpp trick!

Date: Tue, 20 Mar 2012 12:55:09 +0300
Subject: [PATCH 5910/6423] CIFS: Respect negotiated MaxMpxCount

Some servers sets this value less than 50 that was hardcoded and
we lost the connection if when we exceed this limit. Fix this by
respecting this value - not sending more than the server allows.

Subject: [PATCH 5912/6423] NFSv4: It is not safe to dereference lsp->ls_state
 in release_lockowner

It is quite possible for the release_lockowner RPC call to race with the
close RPC call, in which case, we cannot dereference lsp->ls_state in
order to find the nfs_server.

Subject: [PATCH 5913/6423] NFS: Use cond_resched_lock() to reduce latencies in
 the commit scans

Ensure that we conditionally drop the inode->i_lock when it is safe
to do so in the commit loops.
We do so after locking the nfs_page, but before removing it from the
commit list. We can then use list_safe_reset_next to recover the loop
after the lock is retaken.

Subject: [PATCH 5914/6423] SUNRPC/NFS: Add Kbuild dependencies for
 NFS_DEBUG/RPC_DEBUG

This allows us to turn on/off the dprintk() debugging interfaces for
those distributions that don't ship the 'rpcdebug' utility.
It also allows us to add Kbuild dependencies. Specifically, we already
know that dprintk() in general relies on CONFIG_SYSCTL. Now it turns out
that the NFS dprintks depend on CONFIG_CRC32 after we added support
for the filehandle hash.

In 5bfa14ed9f3c, I forgot to initialize res2.flags before calling
pcibios_bus_to_resource(), which depends on the resource type to locate the
correct aperture.  This bug won't hurt x86, which currently never has an
offset between bus and CPU addresses, but will affect other architectures.

Subject: [PATCH 5917/6423] powerpc/PCI: compute I/O space bus-to-resource
 offset consistently

Make sure we compute CPU addresses (resource start/end) the same way both
when we set up the I/O aperture (hose->io_resource) and when we use
pcibios_bus_to_resource() to convert BAR values into resources.

This fixes a build failure ("cast from pointer to integer of different
size" in configs where resource_size_t is 64 bits but pointers are 32 bits)
I introduced in 6c5705fec63d.

Subject: [PATCH 5918/6423] powerpc/PCI: convert devtree bus addresses to
 resource

Normal PCI enumeration via PCI config space uses __pci_read_base(), where
the PCI core applies any bus-to-resource offset.  But powerpc doesn't use
that path when enumerating via the device tree.

In 6c5705fec63d, I converted powerpc to use the PCI core bus-to-resource
conversion, but I missed these powerpc-specific paths.  Some powerpc
platforms fail to boot ("Cannot allocate resource region," "device not
available," etc.) between that commit and this one.

This adds the corresponding bus-to-resource conversion in the paths that
read BAR values from the OF device tree.

Subject: [PATCH 5920/6423] sparc/PCI: convert devtree and arch-probed bus
 addresses to resource

Normal PCI enumeration via PCI config space uses __pci_read_base(), where
the PCI core applies any bus-to-resource offset.  But sparc sometimes
reads PCI config space itself, and sometimes it gets addresses from the
device tree.

In ac1edcc579b6, I converted sparc to use the PCI core bus-to-resource
conversion, but I missed these sparc-specific paths.  I don't have a way
to test it, but I think sparc is broken between that commit and this one.

This patch replaces the sparc-specific pci_resource_adjust() with the
generic pcibios_bus_to_resource() in the following paths:

    pci_cfg_fake_ranges()       (addresses read from PCI config)
    apb_fake_ranges()           (addresses computed based on PCI config)
    of_scan_pci_bridge()        (addresses from OF "ranges" property)

N.B.: Resources of non-P2P bridge devices are set in pci_parse_of_addrs()
and, as far as I can see, never converted to CPU addresses.  I do not
understand why these would be treated differently than bridge windows.

Subject: [PATCH 5925/6423] xen/cpufreq: Disable the cpu frequency scaling
 drivers from loading.

By using the functionality provided by "[CPUFREQ]: provide
disable_cpuidle() function to disable the API."

Under the Xen hypervisor we do not want the initial domain to exercise
the cpufreq scaling drivers. This is b/c the Xen hypervisor is
in charge of doing this as well and we can end up with both the
Linux kernel and the hypervisor trying to change the P-states
leading to weird performance issues.

 scaling drivers.

With patch "xen/cpufreq: Disable the cpu frequency scaling drivers
from loading." we do not have to worry about said drivers loading
themselves before the xen-acpi-processor driver. Hence we can remove
the default selection (=y if CPU frequency drivers were built-in, or
=m if CPU frequency drivers were built as modules), and just
select =m for the default case.

Subject: [PATCH 5927/6423] xen: support pirq_eoi_map

The pirq_eoi_map is a bitmap offered by Xen to check which pirqs need to
be EOI'd without having to issue an hypercall every time.
We use PHYSDEVOP_pirq_eoi_gmfn_v2 to map the bitmap, then if we
succeed we use pirq_eoi_map to check whether pirqs need eoi.

Changes in v3:

- explicitly use PHYSDEVOP_pirq_eoi_gmfn_v2 rather than
PHYSDEVOP_pirq_eoi_gmfn;

- introduce pirq_check_eoi_map, a function to check if a pirq needs an
eoi using the map;

-rename pirq_needs_eoi into pirq_needs_eoi_flag;

- introduce a function pointer called pirq_needs_eoi that is going to be
set to the right implementation depending on the availability of
PHYSDEVOP_pirq_eoi_gmfn_v2.

While testing L2TP functionality, I came across a bug in getsockname().  The
IP address returned within the pppol2tp_addr's addr memember was not being
set to the IP  address in use.  This bug is caused by using inet_sk() on the
wrong socket (the L2TP socket rather than the underlying UDP socket), and was
likely introduced during the addition of L2TPv3 support.

Subject: [PATCH 5931/6423] CLONE_PARENT shouldn't allow to set ->exit_signal

The child must not control its ->exit_signal, it is the parent who
decides which signal the child should use for notification.

This means that CLONE_PARENT should not use "clone_flags & CSIGNAL",
the forking task is the sibling of the new process and their parent
doesn't control exit_signal in this case.

This patch uses ->exit_signal of the forking process, but perhaps
we should simply use SIGCHLD.

We read group_leader->exit_signal lockless, this can race with the
ORIGINAL_SIGNAL -> SIGCHLD transition, but this is fine.

Potentially this change allows to kill self_exec_id/parent_exec_id.

Subject: [PATCH 5932/6423] exit_signal: simplify the "we have changed
 execution domain" logic

exit_notify() checks "tsk->self_exec_id != tsk->parent_exec_id"
to handle the "we have changed execution domain" case.

We can change do_thread() to always set ->exit_signal = SIGCHLD
and remove this check to simplify the code.

We could change setup_new_exec() instead, this looks more logical
because it increments ->self_exec_id. But note that de_thread()
already resets ->exit_signal if it changes the leader, let's keep
both changes close to each other.

Note that we change ->exit_signal lockless, this changes the rules.
Thereafter ->exit_signal is not stable under tasklist but this is
fine, the only possible change is OLDSIG -> SIGCHLD. This can race
with eligible_child() but the race is harmless. We can race with
reparent_leader() which changes our ->exit_signal in parallel, but
it does the same change to SIGCHLD.

The noticeable user-visible change is that the execing task is not
"visible" to do_wait()->eligible_child(__WCLONE) right after exec.
To me this looks more logical, and this is consistent with mt case.

Subject: [PATCH 5933/6423] exit_signal: fix the "parent has changed security
 domain" logic

exit_notify() changes ->exit_signal if the parent already did exec.
This doesn't really work, we are not going to send the signal now
if there is another live thread or the exiting task is traced. The
parent can exec before the last dies or the tracer detaches.

Move this check into do_notify_parent() which actually sends the
signal.

The user-visible change is that we do not change ->exit_signal,
and thus the exiting task is still "clone children" for
do_wait()->eligible_child(__WCLONE). Hopefully this is fine, the
current logic is racy anyway.

From f5339277eb8d3aed37f12a27988366f68ab68930 Mon Sep 17 00:00:00 2001
From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Thu, 15 Mar 2012 18:18:00 +0000
Subject: [PATCH 5940/6423] powerpc: Remove FW_FEATURE ISERIES from arch code

This is no longer selectable, so just remove all the dependent code.

Subject: [PATCH 5944/6423] powerpc/ps3: Do not adjust the wrapper load address

Commit c55aef0e5bc6 "powerpc/boot: Change the load address for the wrapper
to fit the kernel" adjusted the laod address if the uncompressed kernel
was too large.  Ps3 does not compress the kernel and uses a different
linker script, so do not adjust the load address in that case.

fixes this build error:

powerpc64-linux-ld: section .text loaded at [0000000000e00000,0000000000e0721b] overlaps section .kernel:dtb loaded at [0000000000e00000,0000000000e0066f]

Subject: [PATCH 5945/6423] vfs: check i_nlink limits in
 vfs_{mkdir,rename_dir,link}

New field of struct super_block - ->s_max_links.  Maximal allowed
value of ->i_nlink or 0; in the latter case all checks still need
to be done in ->link/->mkdir/->rename instances.  Note that this
limit applies both to directoris and to non-directories.

Subject: [PATCH 5948/6423] vfs: turn generic_drop_inode() into static inline

Once upon a time it used to be much bigger, but these days there's
no point whatsoever keeping it in fs/inode.c, especially since
it's not even needed as initializer for ->drop_inode() - it's the
default and leaving ->drop_inode NULL will do just as well.

+The QNX6 Filesystem
+===================
+
+The qnx6fs is used by newer QNX operating system versions. (e.g. Neutrino)
+It got introduced in QNX 6.4.0 and is used default since 6.4.1.
+
+Option
+======
+
+mmi_fs		Mount filesystem as used for example by Audi MMI 3G system
+
+Specification
+=============
+
+qnx6fs shares many properties with traditional Unix filesystems. It has the
+concepts of blocks, inodes and directories.
+On QNX it is possible to create little endian and big endian qnx6 filesystems.
+This feature makes it possible to create and use a different endianness fs
+for the target (QNX is used on quite a range of embedded systems) plattform
+running on a different endianess.
+The Linux driver handles endianness transparently. (LE and BE)
+
+Blocks
+------
+
+The space in the device or file is split up into blocks. These are a fixed
+size of 512, 1024, 2048 or 4096, which is decided when the filesystem is
+created.
+Blockpointers are 32bit, so the maximum space that can be adressed is
+2^32 * 4096 bytes or 16TB
+
+The superblocks
+---------------
+
+The superblock contains all global information about the filesystem.
+Each qnx6fs got two superblocks, each one having a 64bit serial number.
+That serial number is used to identify the "active" superblock.
+In write mode with reach new snapshot (after each synchronous write), the
+serial of the new master superblock is increased (old superblock serial + 1)
+
+So basically the snapshot functionality is realized by an atomic final
+update of the serial number. Before updating that serial, all modifications
+are done by copying all modified blocks during that specific write request
+(or period) and building up a new (stable) filesystem structure under the
+inactive superblock.
+
+Each superblock holds a set of root inodes for the different filesystem
+parts. (Inode, Bitmap and Longfilenames)
+Each of these root nodes holds information like total size of the stored
+data and the adressing levels in that specific tree.
+If the level value is 0, up to 16 direct blocks can be adressed by each
+node.
+Level 1 adds an additional indirect adressing level where each indirect
+adressing block holds up to blocksize / 4 bytes pointers to data blocks.
+Level 2 adds an additional indirect adressig block level (so, already up
+to 16 * 256 * 256 = 1048576 blocks that can be adressed by such a tree)a
+
+Unused block pointers are always set to ~0 - regardless of root node,
+indirect adressing blocks or inodes.
+Data leaves are always on the lowest level. So no data is stored on upper
+tree levels.
+
+The first Superblock is located at 0x2000. (0x2000 is the bootblock size)
+The Audi MMI 3G first superblock directly starts at byte 0.
+Second superblock position can either be calculated from the superblock
+information (total number of filesystem blocks) or by taking the highest
+device address, zeroing the last 3 bytes and then substracting 0x1000 from
+that address.
+
+0x1000 is the size reserved for each superblock - regardless of the
+blocksize of the filesystem.
+
+Inodes
+------
+
+Each object in the filesystem is represented by an inode. (index node)
+The inode structure contains pointers to the filesystem blocks which contain
+the data held in the object and all of the metadata about an object except
+its longname. (filenames longer than 27 characters)
+The metadata about an object includes the permissions, owner, group, flags,
+size, number of blocks used, access time, change time and modification time.
+
+Object mode field is POSIX format. (which makes things easier)
+
+There are also pointers to the first 16 blocks, if the object data can be
+adressed with 16 direct blocks.
+For more than 16 blocks an indirect adressing in form of another tree is
+used. (scheme is the same as the one used for the superblock root nodes)
+
+The filesize is stored 64bit. Inode counting starts with 1. (whilst long
+filename inodes start with 0)
+
+Directories
+-----------
+
+A directory is a filesystem object and has an inode just like a file.
+It is a specially formatted file containing records which associate each
+name with an inode number.
+'.' inode number points to the directory inode
+'..' inode number points to the parent directory inode
+Eeach filename record additionally got a filename length field.
+
+One special case are long filenames or subdirectory names.
+These got set a filename length field of 0xff in the corresponding directory
+record plus the longfile inode number also stored in that record.
+With that longfilename inode number, the longfilename tree can be walked
+starting with the superblock longfilename root node pointers.
+
+Special files
+-------------
+
+Symbolic links are also filesystem objects with inodes. They got a specific
+bit in the inode mode field identifying them as symbolic link.
+The directory entry file inode pointer points to the target file inode.
+
+Hard links got an inode, a directory entry, but a specific mode bit set,
+no block pointers and the directory file record pointing to the target file
+inode.
+
+Character and block special devices do not exist in QNX as those files
+are handled by the QNX kernel/drivers and created in /dev independant of the
+underlaying filesystem.
+
+Long filenames
+--------------
+
+Long filenames are stored in a seperate adressing tree. The staring point
+is the longfilename root node in the active superblock.
+Each data block (tree leaves) holds one long filename. That filename is
+limited to 510 bytes. The first two starting bytes are used as length field
+for the actual filename.
+If that structure shall fit for all allowed blocksizes, it is clear why there
+is a limit of 510 bytes for the actual filename stored.
+
+Bitmap
+------
+
+The qnx6fs filesystem allocation bitmap is stored in a tree under bitmap
+root node in the superblock and each bit in the bitmap represents one
+filesystem block.
+The first block is block 0, which starts 0x1000 after superblock start.
+So for a normal qnx6fs 0x3000 (bootblock + superblock) is the physical
+address at which block 0 is located.
+
+Bits at the end of the last bitmap block are set to 1, if the device is
+smaller than addressing space in the bitmap.
+
+Bitmap system area
+------------------
+
+The bitmap itself is devided into three parts.
+First the system area, that is split into two halfs.
+Then userspace.
+
+The requirement for a static, fixed preallocated system area comes from how
+qnx6fs deals with writes.
+Each superblock got it's own half of the system area. So superblock #1
+always uses blocks from the lower half whilst superblock #2 just writes to
+blocks represented by the upper half bitmap system area bits.
+
+Bitmap blocks, Inode blocks and indirect addressing blocks for those two
+tree structures are treated as system blocks.
+
+The rational behind that is that a write request can work on a new snapshot
+(system area of the inactive - resp. lower serial numbered superblock) while
+at the same time there is still a complete stable filesystem structer in the
+other half of the system area.
+
+When finished with writing (a sync write is completed, the maximum sync leap
+time or a filesystem sync is requested), serial of the previously inactive
+superblock atomically is increased and the fs switches over to that - then
+stable declared - superblock.
+
+For all data outside the system area, blocks are just copied while writing.

we can do that right in __put_ioctx(); as the result, the loop
in ioctx_alloc() can be killed.

+/* These all interelate for performance.
+**
+** If the journal block count is smaller than n transactions, you lose speed.
+** I don't know what n is yet, I'm guessing 8-16.
+**
+** typical transaction size depends on the application, how often fsync is
+** called, and how many metadata blocks you dirty in a 30 second period.
+** The more small files (<16k) you use, the larger your transactions will
+** be.
+**
+** If your journal fills faster than dirty buffers get flushed to disk, it must flush them before allowing the journal
+** to wrap, which slows things down.  If you need high speed meta data updates, the journal should be big enough
+** to prevent wrapping before dirty meta blocks get to disk.
+**
+** If the batch max is smaller than the transaction max, you'll waste space at the end of the journal
+** because journal_end sets the next transaction to start at 0 if the next transaction has any chance of wrapping.
+**
+** The large the batch max age, the better the speed, and the more meta data changes you'll lose after a crash.

-/* These all interelate for performance.
-**
-** If the journal block count is smaller than n transactions, you lose speed.
-** I don't know what n is yet, I'm guessing 8-16.
-**
-** typical transaction size depends on the application, how often fsync is
-** called, and how many metadata blocks you dirty in a 30 second period.
-** The more small files (<16k) you use, the larger your transactions will
-** be.
-**
-** If your journal fills faster than dirty buffers get flushed to disk, it must flush them before allowing the journal
-** to wrap, which slows things down.  If you need high speed meta data updates, the journal should be big enough
-** to prevent wrapping before dirty meta blocks get to disk.
-**
-** If the batch max is smaller than the transaction max, you'll waste space at the end of the journal
-** because journal_end sets the next transaction to start at 0 if the next transaction has any chance of wrapping.
-**
-** The large the batch max age, the better the speed, and the more meta data changes you'll lose after a crash.

pointless, since the only caller will want the physical block

sb_bread()

Subject: [PATCH 6005/6423] hfsplus: change finder_info to u32

The finder_info block in the hfsplus volume header is currently defined as
an array of 8 bit values, but TN1150 defines it as being an array of 32 bit
values. Fix for convenience.

Subject: [PATCH 6006/6423] hfsplus: add an ioctl to bless files

Making an hfsplus partition bootable requires the ability to "bless" a
file by putting its inode number in the volume header. Doing this from
userspace on a mounted filesystem is impractical since the kernel will
write back the original values on unmount. Add an ioctl to allow userspace
to update the volume header information based on the target file.

no point, really - the only instance that cares about those arguments of
tlb_finish_mmu() is itanic and there we explicitly check if that's called
from exit_mmap() (i.e. that ->fullmm is set), in which case we ignore those
arguments completely.

Subject: [PATCH 6015/6423] bfin_sport: add support for ADC/DAC.

In order to support ADC/DAC demo, add NDSO_MODE mode to bfin_sport.c.
After that userspace apps like ndso/awg can work fine.

No other SPI controller has this field, and SPI clients should be setting
this up in their own drivers.  So drop it from the Blackfin controller to
keep people from using it.

Subject: [PATCH 6030/6423] arch/blackfin: don't generate random mac in
 bfin_get_ether_addr()

Changed bfin_get_ether_addr() to return a state and to
set no random mac address if the board don't provide one.

Let the caller of bfin_get_ether_addr() set a random mac
address if the return value is not 0.

v2: don't set random mac in bfin_get_ether_addr()

+usRequestedPWMFreqInHz:           When it's set to 0x0 by SBIOS: the LCD BackLight is not controlled by GPU(SW). 
+                                  Any attempt to change BL using VBIOS function or enable VariBri from PP table is not effective since ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==0;
+                                  
+                                  When it's set to a non-zero frequency, the BackLight is controlled by GPU (SW) in one of two ways below:
+                                  1. SW uses the GPU BL PWM output to control the BL, in chis case, this non-zero frequency determines what freq GPU should use;
+                                  VBIOS will set up proper PWM frequency and ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1,as the result,
+                                  Changing BL using VBIOS function is functional in both driver and non-driver present environment; 
+                                  and enabling VariBri under the driver environment from PP table is optional.
+
+                                  2. SW uses other means to control BL (like DPCD),this non-zero frequency serves as a flag only indicating
+                                  that BL control from GPU is expected.
+                                  VBIOS will NOT set up PWM frequency but make ATOM_BIOS_INFO_BL_CONTROLLED_BY_GPU==1
+                                  Changing BL using VBIOS function could be functional in both driver and non-driver present environment,but
+                                  it's per platform 
+                                  and enabling VariBri under the driver environment from PP table is optional.

Subject: [PATCH 6047/6423] drm/radeon/kms/atom: add support for crtc power
 gating

Each pair of crtcs (0/1, 2/3, 4/5) can be power gated.
Make sure the power is applied when the crtc is in use and
only power down the pair when both are off.

From dfcf5f36529d69eb35f4fdedfa6f244c5249698c Mon Sep 17 00:00:00 2001

Subject: [PATCH 6058/6423] drm/radeon/kms: add support for the CONST IB to the
 CS ioctl

This adds a new chunk id to the CS ioctl to support the
INDIRECT_BUFFER_CONST packet.

On SI, the CP adds a new engine called the CE (Constant Engine)
which runs simulatenously with the DE (Drawing Engine, formerly
called the ME).  This allows the CP to process two related IBs
simultaneously.  The CE is tasked with loading the constant data
(constant buffers, resource descriptors, samplers, etc.) while
the DE loads context register state and issues drawing commands.
It's up to the userspace application to sychronize the CE and the
DE using special synchronization packets.

Subject: [PATCH 6061/6423] drm/radeon/kms: add ucode loading for SI

Currently the driver required 5 sets of ucode:
1. pfp - pre-fetch parser, part of the CP
2. me - micro engine, part of the CP
3. ce - constant engine, part of the CP
4. rlc - interrupt controller
5. mc - memory controller

Subject: [PATCH 6087/6423] fbdev: remove dependency of FB_SH_MOBILE_MERAM from
 FB_SH_MOBILE_LCDC

MERAM can be used for other IP blocks as well in the future.
It doesn't necessarily mean that the MERAM driver depends on the LCDC.
This patch corrects dependency.

Subject: [PATCH 6088/6423] fbdev: sh_mipi_dsi: add extra phyctrl for
 sh_mipi_dsi_info

sh_mipi uses some clocks, but the method of setup depends on CPU.

Current SuperH (like sh73a0) can control all of these clocks
by CPG (Clock Pulse Generator).
It means we can control it by clock framework only.
But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS,
and only sh7372 has PHYCTRL::PLLDS.

But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was
overwrote since the callback timing of clock setting was changed
by c2658b70f06108361aa5024798f9c1bf47c73374
(fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()).
To solve this issue, this patch adds extra .phyctrl.

This patch adds detail explanation for unclear mipi settings
and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

Subject: [PATCH 6096/6423] ktest: Add warning when bugs are ignored

When IGNORE_ERRORS is set, ktest will not fail a test if a backtrace
is detected. But this can be an issue if the user added it in the
config but forgot to remove it. They may be left wondering why their
test did not fail, or even worse, why their bisect gave the wrong
commit.

Add a warning in the output if IGNORE_WARNINGS is set, and ktest detects
a kernel error.

Subject: [PATCH 6097/6423] ktest: Add SCP_TO_TARGET_INSTALL option

Currently the option used to scp both the modules to the target as well
as the kernel image are the same (SCP_TO_TARGET). But some embedded
boards may require them to be different. The modules may need to be put
directly on the board, but the kernel image may need to go to a
tftpserver.

Add the option SCP_TO_TARGET_INSTALL that will allow the user to change
the config so that they may have the modules and image got to different
machines.

Subject: [PATCH 6098/6423] ktest: Fix SWITCH_TO_GOOD to also reboot the
 machine

When the option SWITCH_TO_GOOD is set, it will be called when the system
needs to reboot to the good server. But currently, this keeps the reboot
from happening. The SWITCH_TO_GOOD is just a way to get to a new kernel,
it may not mean to not reboot.

Subject: [PATCH 6099/6423] OMAPDSS: register dss drivers in module init

We do the dss driver registration in a rather strange way: we have the
higher level omapdss driver, and we use that driver's probe function to
register the drivers for the rest of the dss devices.

There doesn't seem to be any reason for that, and additionally the
soon-to-be-merged patch "ARM: OMAP: omap_device: remove
omap_device_parent" will break omapdss initialization with the current
registration model.

This patch changes the registration for all drivers to happen at the
same place, in the init of the module.

 execute NX-protected page"

This reverts commit ec0d22e4d563e7cce9f6678e2000900755c2989d.

This patch requires exporting 'pcibios_enabled' to avoid breaking
modular uvesafb builds. As this gets some opposition by Alan Cox it
needs more discussion, revert the patch for now.

Date: Mon, 19 Mar 2012 20:47:58 -0700
Subject: [PATCH 6109/6423] pnfs-obj: autologin: Add support for protocol
 autologin

The pnfs-objects protocol mandates that we autologin into devices not
present in the system, according to information specified in the
get_device_info returned from the server.

The Protocol specifies two login hints.
1. An IP address:port combination
2. A string URI which is constructed as a URL with a protocol prefix
   followed by :// and a string as address. For each  protocol prefix
   the string-address format might be different.

We only support the second option. The first option is just redundant
to the second one.
NOTE: The Kernel part of autologin does not parse the URI string. It
just channels it to a user-mode script. So any new login protocols should
only update the user-mode script which is a part of the nfs-utils package,
but the Kernel need not change.

We implement the autologin by using the call_usermodehelper() API.
(Thanks to Steve Dickson <steved@redhat.com> for pointing it out)
So there is no running daemon needed, and/or special setup.

We Add the osd_login_prog Kernel module parameters which defaults to:
	/sbin/osd_login

Kernel try's to upcall the program specified in osd_login_prog. If the file is
not found or the execution fails Kernel will disable any farther upcalls, by
zeroing out  osd_login_prog, Until Admin re-enables it by setting the
osd_login_prog parameter to a proper program.

Also add text about the osd_login program command line API to:
	Documentation/filesystems/nfs/pnfs.txt
and documentation of the new  osd_login_prog  module parameter to:
	Documentation/kernel-parameters.txt

TODO: Add timeout option in the case osd_login program gets
              stuck

+
+layout drivers
+--------------
+
+PNFS utilizes what is called layout drivers. The STD defines 3 basic
+layout types: "files" "objects" and "blocks". For each of these types
+there is a layout-driver with a common function-vectors table which
+are called by the nfs-client pnfs-core to implement the different layout
+types.
+
+Files-layout-driver code is in: fs/nfs/nfs4filelayout.c && nfs4filelayoutdev.c
+Objects-layout-deriver code is in: fs/nfs/objlayout/.. directory
+Blocks-layout-deriver code is in: fs/nfs/blocklayout/.. directory
+
+objects-layout setup
+--------------------
+
+As part of the full STD implementation the objlayoutdriver.ko needs, at times,
+to automatically login to yet undiscovered iscsi/osd devices. For this the
+driver makes up-calles to a user-mode script called *osd_login*
+
+The path_name of the script to use is by default:
+	/sbin/osd_login.
+This name can be overridden by the Kernel module parameter:
+	objlayoutdriver.osd_login_prog
+
+If Kernel does not find the osd_login_prog path it will zero it out
+and will not attempt farther logins. An admin can then write new value
+to the objlayoutdriver.osd_login_prog Kernel parameter to re-enable it.
+
+The /sbin/osd_login is part of the nfs-utils package, and should usually
+be installed on distributions that support this Kernel version.
+
+The API to the login script is as follows:
+	Usage: $0 -u <URI> -o <OSDNAME> -s <SYSTEMID>
+	Options:
+		-u		target uri e.g. iscsi://<ip>:<port>
+				(allways exists)
+				(More protocols can be defined in the future.
+				 The client does not interpret this string it is
+				 passed unchanged as recieved from the Server)
+		-o		osdname of the requested target OSD
+				(Might be empty)
+				(A string which denotes the OSD name, there is a
+				 limit of 64 chars on this string)
+		-s 		systemid of the requested target OSD
+				(Might be empty)
+				(This string, if not empty is always an hex
+				 representation of the 20 bytes osd_system_id)

Subject: [PATCH 6113/6423] ktest: Allow a test to override REBOOT_ON_SUCCESS

The option REBOOT_ON_SUCCESS is global, and will have the machine reboot
the the box if all tests are successful. But a test may not want the
machine to reboot, and perhaps have the kernel it loaded be used to
install the next kernel. Or the last test may set up a kernel that the
user may want to look at. In this case, the user could have the global
option REBOOT_ON_SUCCESS be true, but if a test is defined to run at the
end, that test can override the global option and keep the kernel it
installed for the user to log in with.

Subject: [PATCH 6114/6423] NFS: fix sb->s_id in nfs debug prints

NFS bdi flush thread in ps output is printed like "flush-<major number
in decimal>:<minor number in decimal>"
For example:
$ ps aux | grep flush
 2079 root         0 SW   [flush-0:18]
                                 ^^^^

nfs_bdi_register()
==> bdi_register_dev()
==> bdi_register(bdi, NULL, "%u:%u", MAJOR(dev), MINOR(dev));
                             ^^^^^

However, NFS sb->s_id store major:minor number in hex:

nfs_initialise_sb()
==>         snprintf(sb->s_id, sizeof(sb->s_id),
                 "%x:%x", MAJOR(sb->s_dev), MINOR(sb->s_dev));
                  ^^^^^

If we enable nfs debug prints using command:
$ rpcdebug -m nfs -s all

write to a file:
$ dd if=/dev/zero of=<NFS Mount>/testfile.txt bs=32768 count=1

Without Patch:
[ 2431.032000] NFS:     0 initiated write call (req 0:12/40, 32768 bytes
@ offset 0)                                         ^^^^

With Patch:
[ 2431.032000] NFS:     0 initiated write call (req 0:18/40, 32768 bytes
@ offset 0)                                         ^^^^

We should store NFS "s->s_id" in decimal to avoid confusion between NFS
flush thread name(in ps output) and NFS debug prints.

Which is OK - the machines do not have P-states, so we fail to register
to process the _PXX states. But there is no need to WARN the user
of it.

Subject: [PATCH 6117/6423] cifs: fix issue mounting of DFS ROOT when
 redirecting from one domain controller to the next

This patch fixes an issue when cifs_mount receives a
STATUS_BAD_NETWORK_NAME error during cifs_get_tcon but is able to
continue after an DFS ROOT referral. In this case, the return code
variable is not reset prior to trying to mount from the system referred
to. Thus, is_path_accessible is not executed and the final DFS referral
is not performed causing a mount error.

Use case: In DNS, example.com  resolves to the secondary AD server
ad2.example.com Our primary domain controller is ad1.example.com and has
a DFS redirection set up from \\ad1\share\Users to \\files\share\Users.
Mounting \\example.com\share\Users fails.

Regression introduced by commit 724d9f1.

Subject: [PATCH 6119/6423] CIFS: Introduce credit-based flow control

and send no more than credits value requests at once. For SMB/CIFS
it's trivial: increment this value by receiving any message and
decrement by sending one.

napi->skb is allocated in napi_get_frags() using
netdev_alloc_skb_ip_align(), with a reserve of NET_SKB_PAD +
NET_IP_ALIGN bytes.

However, when such skb is recycled in napi_reuse_skb(), it ends with a
reserve of NET_IP_ALIGN which is suboptimal.

Subject: [PATCH 6127/6423] mm: thp: fix pmd_bad() triggering in code paths
 holding mmap_sem read mode

In some cases it may happen that pmd_none_or_clear_bad() is called with
the mmap_sem hold in read mode.  In those cases the huge page faults can
allocate hugepmds under pmd_none_or_clear_bad() and that can trigger a
false positive from pmd_bad() that will not like to see a pmd
materializing as trans huge.

It's not khugepaged causing the problem, khugepaged holds the mmap_sem
in write mode (and all those sites must hold the mmap_sem in read mode
to prevent pagetables to go away from under them, during code review it
seems vm86 mode on 32bit kernels requires that too unless it's
restricted to 1 thread per process or UP builds).  The race is only with
the huge pagefaults that can convert a pmd_none() into a
pmd_trans_huge().

Effectively all these pmd_none_or_clear_bad() sites running with
mmap_sem in read mode are somewhat speculative with the page faults, and
the result is always undefined when they run simultaneously.  This is
probably why it wasn't common to run into this.  For example if the
madvise(MADV_DONTNEED) runs zap_page_range() shortly before the page
fault, the hugepage will not be zapped, if the page fault runs first it
will be zapped.

Altering pmd_bad() not to error out if it finds hugepmds won't be enough
to fix this, because zap_pmd_range would then proceed to call
zap_pte_range (which would be incorrect if the pmd become a
pmd_trans_huge()).

The simplest way to fix this is to read the pmd in the local stack
(regardless of what we read, no need of actual CPU barriers, only
compiler barrier needed), and be sure it is not changing under the code
that computes its value.  Even if the real pmd is changing under the
value we hold on the stack, we don't care.  If we actually end up in
zap_pte_range it means the pmd was not none already and it was not huge,
and it can't become huge from under us (khugepaged locking explained
above).

All we need is to enforce that there is no way anymore that in a code
path like below, pmd_trans_huge can be false, but pmd_none_or_clear_bad
can run into a hugepmd.  The overhead of a barrier() is just a compiler
tweak and should not be measurable (I only added it for THP builds).  I
don't exclude different compiler versions may have prevented the race
too by caching the value of *pmd on the stack (that hasn't been
verified, but it wouldn't be impossible considering
pmd_none_or_clear_bad, pmd_bad, pmd_trans_huge, pmd_none are all inlines
and there's no external function called in between pmd_trans_huge and
pmd_none_or_clear_bad).

		if (pmd_trans_huge(*pmd)) {
			if (next-addr != HPAGE_PMD_SIZE) {
				VM_BUG_ON(!rwsem_is_locked(&tlb->mm->mmap_sem));
				split_huge_page_pmd(vma->vm_mm, pmd);
			} else if (zap_huge_pmd(tlb, vma, pmd, addr))
				continue;
			/* fall through */
		}
		if (pmd_none_or_clear_bad(pmd))

Because this race condition could be exercised without special
privileges this was reported in CVE-2012-1179.

The race was identified and fully explained by Ulrich who debugged it.
I'm quoting his accurate explanation below, for reference.

      mapcount 0 page_mapcount 1
      kernel BUG at mm/huge_memory.c:1384!

    At some point prior to the panic, a "bad pmd ..." message similar to the
    following is logged on the console:

      mm/memory.c:145: bad pmd ffff8800376e1f98(80000000314000e7).

    The "bad pmd ..." message is logged by pmd_clear_bad() before it clears
    the page's PMD table entry.

        143 void pmd_clear_bad(pmd_t *pmd)
        144 {
    ->  145         pmd_ERROR(*pmd);
        146         pmd_clear(pmd);
        147 }

    After the PMD table entry has been cleared, there is an inconsistency
    between the actual number of PMD table entries that are mapping the page
    and the page's map count (_mapcount field in struct page). When the page
    is subsequently reclaimed, __split_huge_page() detects this inconsistency.

       1381         if (mapcount != page_mapcount(page))
       1382                 printk(KERN_ERR "mapcount %d page_mapcount %d\n",
       1383                        mapcount, page_mapcount(page));
    -> 1384         BUG_ON(mapcount != page_mapcount(page));

    The root cause of the problem is a race of two threads in a multithreaded
    process. Thread B incurs a page fault on a virtual address that has never
    been accessed (PMD entry is zero) while Thread A is executing an madvise()
    system call on a virtual address within the same 2 MB (huge page) range.

                  spin_unlock(&mm->page_table_lock)

    The mmap_sem does not prevent the race because both threads are acquiring
    it in shared mode (down_read).  Thread B holds the page_table_lock while
    the page's map count and PMD table entry are updated.  However, Thread A
    does not synchronize on that lock.

Subject: [PATCH 6128/6423] fs/namei.c: fix warnings on 32-bit

i386 allnoconfig:

  fs/namei.c: In function 'has_zero':
  fs/namei.c:1617: warning: integer constant is too large for 'unsigned long' type
  fs/namei.c:1617: warning: integer constant is too large for 'unsigned long' type
  fs/namei.c: In function 'hash_name':
  fs/namei.c:1635: warning: integer constant is too large for 'unsigned long' type

There must be a tidier way of doing this.

Subject: [PATCH 6130/6423] seq_file: fix mishandling of consecutive pread()
 invocations.

The following program illustrates the problem:

    char buf[8192];

    int fd = open("/proc/self/maps", O_RDONLY);

    n = pread(fd, buf, sizeof(buf), 0);
    printf("%d\n", n);

    /* lseek(fd, 0, SEEK_CUR); */ /* Uncomment to work around */

    n = pread(fd, buf, sizeof(buf), 0);
    printf("%d\n", n);

The second printf() prints zero, but uncommenting the lseek() corrects its
behaviour.

To fix, make seq_read() mirror seq_lseek() when processing changes in
*ppos.  Restore m->version first, then if required traverse and update
read_pos on success.

Subject: [PATCH 6131/6423] xtensa: don't reimplement force_sigsegv()

Instead of open coding the sequence from force_sigsegv() just call it.
This also fixes a bug because we were modifying ka->sa.sa_handler (which
is a copy of sighand->action[]), whereas the intention of the code was to
modify sighand->action[] directly.

As the original code was working with a copy it had no effect on signal
delivery.

handle_signal().

Furthermore, because we were modifying ka->sa.sa_handler (which is a

code actually had no effect on signal delivery.

Subject: [PATCH 6134/6423] xtensa: use set_current_blocked() and
 block_sigmask()

As described in commit e6fa16ab9c1e ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate code
across architectures.  In the past some architectures got this code wrong,
so using this helper function should stop that from happening again.

Subject: [PATCH 6136/6423] mm, oom: avoid looping when chosen thread detaches
 its mm

oom_kill_task() returns non-zero iff the chosen process does not have any
threads with an attached ->mm.

In such a case, it's better to just return to the page allocator and retry
the allocation because memory could have been freed in the interim and the
oom condition may no longer exist.  It's unnecessary to loop in the oom
killer and find another thread to kill.

This allows both oom_kill_task() and oom_kill_process() to be converted to
void functions.  If the oom condition persists, the oom killer will be
recalled.

Subject: [PATCH 6137/6423] mm, oom: fold oom_kill_task() into
 oom_kill_process()

oom_kill_task() has a single caller, so fold it into its parent function,
oom_kill_process().  Slightly reduces the number of lines in the oom
killer.

Subject: [PATCH 6138/6423] mm, oom: do not emit oom killer warning if chosen
 thread is already exiting

If a thread is chosen for oom kill and is already PF_EXITING, then the oom
killer simply sets TIF_MEMDIE and returns.  This allows the thread to have
access to memory reserves so that it may quickly exit.  This logic is
preceeded with a comment saying there's no need to alarm the sysadmin.
This patch adds truth to that statement.

There's no need to emit any warning about the oom condition if the thread
is already exiting since it will not be killed.  In this condition, just
silently return the oom killer since its only giving access to memory
reserves and is otherwise a no-op.

Subject: [PATCH 6139/6423] mm, oom: introduce independent oom killer ratelimit
 state

printk_ratelimit() uses the global ratelimit state for all printks.  The
oom killer should not be subjected to this state just because another
subsystem or driver may be flooding the kernel log.

This patch introduces printk ratelimiting specifically for the oom killer.

Subject: [PATCH 6140/6423] mm: add rss counters consistency check

Warn about non-zero rss counters at final mmdrop.

This check will prevent reoccurences of bugs such as that fixed in "mm:
fix rss count leakage during migration".

I didn't hide this check under CONFIG_VM_DEBUG because it rather small and
rss counters cover whole page-table management, so this is a good
invariant.

Subject: [PATCH 6143/6423] mm: vmscan: fix misused nr_reclaimed in
 shrink_mem_cgroup_zone()

The value of nr_reclaimed is the number of pages reclaimed in the current
round of the loop, whereas nr_to_reclaim should be compared with the
number of pages reclaimed in all rounds.

In each round of the loop, reclaimed pages are cut off from the reclaim
goal, and the loop stops once the goal achieved.

Subject: [PATCH 6144/6423] mm: make swapin readahead skip over holes

Ever since abandoning the virtual scan of processes, for scalability
reasons, swap space has been a little more fragmented than before.  This
can lead to the situation where a large memory user is killed, swap space
ends up full of "holes" and swapin readahead is totally ineffective.

On my home system, after killing a leaky firefox it took over an hour to
page just under 2GB of memory back in, slowing the virtual machines down
to a crawl.

This patch makes swapin readahead simply skip over holes, instead of
stopping at them.  This allows the system to swap things back in at rates
of several MB/second, instead of a few hundred kB/second.

The checks done in valid_swaphandles are already done in
read_swap_cache_async as well, allowing us to remove a fair amount of
code.

Subject: [PATCH 6145/6423] vmscan: reclaim at order 0 when compaction is
 enabled

When built with CONFIG_COMPACTION, kswapd should not try to free
contiguous pages, because it is not trying hard enough to have a real
chance at being successful, but still disrupts the LRU enough to break
other things.

Do not do higher order page isolation unless we really are in lumpy
reclaim mode.

Stop reclaiming pages once we have enough free pages that compaction can
deal with things, and we hit the normal order 0 watermarks used by kswapd.

Also remove a line of code that increments balanced right before exiting
the function.

Subject: [PATCH 6146/6423] vmscan: kswapd carefully call compaction

With CONFIG_COMPACTION enabled, kswapd does not try to free contiguous
free pages, even when it is woken for a higher order request.

This could be bad for eg.  jumbo frame network allocations, which are done
from interrupt context and cannot compact memory themselves.  Higher than
before allocation failure rates in the network receive path have been
observed in kernels with compaction enabled.

Teach kswapd to defragment the memory zones in a node, but only if
required and compaction is not deferred in a zone.

Subject: [PATCH 6147/6423] vmscan: only defer compaction for failed order and
 higher

Currently a failed order-9 (transparent hugepage) compaction can lead to
memory compaction being temporarily disabled for a memory zone.  Even if
we only need compaction for an order 2 allocation, eg.  for jumbo frames
networking.

The fix is relatively straightforward: keep track of the highest order at
which compaction is succeeding, and only defer compaction for orders at
which compaction is failing.

The RECLAIM_FS notations indicate that it's doing the GFP_FS checking that
Nick hacked into lockdep a while back: I think we're intended to read that
"<Interrupt>" in the DEADLOCK scenario as "<Direct reclaim>".

I'm hazy, I have not reached any conclusion as to whether it's right to
complain or not; but I believe it's uneasy about kswapd now doing the
mutex_lock(&pcpu_alloc_mutex) which lru_add_drain_all() entails.  Nor have
I reached any conclusion as to whether it's important for kswapd to do
that draining or not.

But so as not to get blocked on this, with lockdep disabled from giving
further reports, here's a patch which removes the lru_add_drain_all() from
kswapd's callpath (and calls it only once from compact_nodes(), instead of
once per node).

"order" is -1 when compacting via /proc/sys/vm/compact_memory.  Making

Subject: [PATCH 6152/6423] mm: do not reset cached_hole_size when vma is
 unmapped

In the current code, cached_hole_size is set to the maximum value if the
unmapped vma is less that free_area_cache so the next search will search
from the base address.

Actually, we can keep cached_hole_size so that if the next required size
is more than cached_hole_size, it can search from free_area_cache.

Subject: [PATCH 6153/6423] mm: search from free_area_cache for the bigger size

If the required size is bigger than cached_hole_size it is better to
search from free_area_cache - it is easier to get a free region,
specifically for the 64 bit process whose address space is large enough

Do it just as hugetlb_get_unmapped_area_topdown() in arch/x86/mm/hugetlbpage.c

Subject: [PATCH 6154/6423] pagemap: avoid splitting thp when reading
 /proc/pid/pagemap

Thp split is not necessary if we explicitly check whether pmds are mapping
thps or not.  This patch introduces this check and adds code to generate
pagemap entries for pmds mapping thps, which results in less performance
impact of pagemap on thp.

Subject: [PATCH 6155/6423] thp: optimize away unnecessary page table locking

Currently when we check if we can handle thp as it is or we need to split
it into regular sized pages, we hold page table lock prior to check
whether a given pmd is mapping thp or not.  Because of this, when it's not
"huge pmd" we suffer from unnecessary lock/unlock overhead.  To remove it,
this patch introduces a optimized check function and replace several
similar logics with it.

This flag shows that a given page is a subpage of a transparent hugepage.
It helps us debug and test the kernel by showing physical address of thp.

Subject: [PATCH 6158/6423] pagemap: introduce data structure for pagemap entry

Currently a local variable of pagemap entry in pagemap_pte_range() is
named pfn and typed with u64, but it's not correct (pfn should be unsigned
long.)

This patch introduces special type for pagemap entries and replaces code
with it.

Subject: [PATCH 6160/6423] mm: vmscan: forcibly scan highmem if there are too
 many buffer_heads pinning highmem

Stuart Foster reported on bugzilla that copying large amounts of data
from NTFS caused an OOM kill on 32-bit X86 with 16G of memory.  Andrew
Morton correctly identified that the problem was NTFS was using 512
blocks meaning each page had 8 buffer_heads in low memory pinning it.

In the past, direct reclaim used to scan highmem even if the allocating
process did not specify __GFP_HIGHMEM but not any more.  kswapd no longer
will reclaim from zones that are above the high watermark.  The intention
in both cases was to minimise unnecessary reclaim.  The downside is on
machines with large amounts of highmem that lowmem can be fully consumed
by buffer_heads with nothing trying to free them.

The following patch is based on a suggestion by Andrew Morton to extend
the buffer_heads_over_limit case to force kswapd and direct reclaim to
scan the highmem zone regardless of the allocation request or watermarks.

Addresses https://bugzilla.kernel.org/show_bug.cgi?id=42578

Subject: [PATCH 6161/6423] mm: hugetlb: defer freeing pages when gathering
 surplus pages

When gathering surplus pages, the number of needed pages is recomputed
after reacquiring hugetlb lock to catch changes in resv_huge_pages and
free_huge_pages.  Plus it is recomputed with the number of newly allocated
pages involved.

Thus freeing pages can be deferred a bit to see if the final page request
is satisfied, though pages could be allocated less than needed.

Subject: [PATCH 6164/6423] vmscan: handle isolated pages with lru lock
 released

When shrinking inactive lru list, isolated pages are queued on locally
private list, so the lock-hold time could be reduced if pages are counted
without lock protection.

To achieve that, firstly updating reclaim stat is delayed until the
putback stage, after reacquiring the lru lock.

Secondly, operations related to vm and zone stats are now proteced with
preemption disabled as they are per-cpu operations.

Subject: [PATCH 6167/6423] procfs: mark thread stack correctly in
 proc/<pid>/maps

Stack for a new thread is mapped by userspace code and passed via
sys_clone.  This memory is currently seen as anonymous in
/proc/<pid>/maps, which makes it difficult to ascertain which mappings
are being used for thread stacks.  This patch uses the individual task
stack pointers to determine which vmas are actually thread stacks.

For a multithreaded program like the following:

	#include <pthread.h>

	void *thread_main(void *foo)
	{
		while(1);
	}

	int main()
	{
		pthread_t t;
		pthread_create(&t, NULL, thread_main, NULL);
		pthread_join(t, NULL);

proc/PID/maps looks like the following:

Here, one could guess that 7f8a44492000-7f8a44c92000 is a stack since
the earlier vma that has no permissions (7f8a44e3d000-7f8a4503d000) but
that is not always a reliable way to find out which vma is a thread
stack.  Also, /proc/PID/maps and /proc/PID/task/TID/maps has the same
content.

With this patch in place, /proc/PID/task/TID/maps are treated as 'maps
as the task would see it' and hence, only the vma that that task uses as
stack is marked as [stack].  All other 'stack' vmas are marked as
anonymous memory.  /proc/PID/maps acts as a thread group level view,
where all thread stack vmas are marked as [stack:TID] where TID is the
process ID of the task that uses that vma as stack, while the process
stack is marked as [stack].

So /proc/PID/maps will look like this:

    00400000-00401000 r-xp 00000000 fd:0a 3671804                            /home/siddhesh/a.out

Thus marking all vmas that are used as stacks by the threads in the
thread group along with the process stack.  The task level maps will
however like this:

Subject: [PATCH 6168/6423] mm, oom: force oom kill on sysrq+f

The oom killer chooses not to kill a thread if:

 - an eligible thread has already been oom killed and has yet to exit,
   and

 - an eligible thread is exiting but has yet to free all its memory and
   is not the thread attempting to currently allocate memory.

SysRq+F manually invokes the global oom killer to kill a memory-hogging
task.  This is normally done as a last resort to free memory when no
progress is being made or to test the oom killer itself.

For both uses, we always want to kill a thread and never defer.  This
patch causes SysRq+F to always kill an eligible thread and can be used to
force a kill even if another oom killed thread has failed to exit.

Subject: [PATCH 6170/6423] thp: allow a hwpoisoned head page to be put back to
 LRU

Andrea Arcangeli pointed out to me that a check in __memory_failure()
which was intended to prevent THP tail pages from being checked for the
absence of the PG_lru flag (something that is always the case), was also
preventing THP head pages from being checked.

A THP head page could actually benefit from the call to shake_page() by
ending up being put back to a LRU, provided it had been waiting in a
pagevec array.

Andrea suggested that the "!PageTransCompound(p)" in the if-statement
should be replaced by a "!PageTransTail(p)", thus allowing THP head pages
to be checked and possibly shaken.

Subject: [PATCH 6171/6423] mm: fix move/migrate_pages() race on task struct

Migration functions perform the rcu_read_unlock too early.  As a result
the task pointed to may change from under us.  This can result in an oops,
as reported by Dave Hansen in https://lkml.org/lkml/2012/2/23/302.

The following patch extend the period of the rcu_read_lock until after the
permissions checks are done.  We also take a refcount so that the task
reference is stable when calling security check functions and performing
cpuset node validation (which takes a mutex).

The refcount is dropped before actual page migration occurs so there is no
change to the refcounts held during page migration.

Also move the determination of the mm of the task struct to immediately
before the do_migrate*() calls so that it is clear that we switch from
handling the task during permission checks to the mm for the actual
migration.  Since the determination is only done once and we then no
longer use the task_struct we can be sure that we operate on a specific
address space that will not change from under us.

Subject: [PATCH 6172/6423] mm: drain percpu lru add/rotate page-vectors on cpu
 hot-unplug

This cpu hotplug hook was accidentally removed in commit 00a62ce91e55
("mm: fix Committed_AS underflow on large NR_CPUS environment")

The visible effect of this accident: some pages are borrowed in per-cpu
page-vectors.  Truncate can deal with it, but these pages cannot be
reused while this cpu is offline.  So this is like a temporary memory
leak.

Subject: [PATCH 6173/6423] bootmem/sparsemem: remove limit constraint in
 alloc_bootmem_section

While testing AMS (Active Memory Sharing) / CMO (Cooperative Memory
Overcommit) on powerpc, we tripped the following:

  [c000000000c03f90] c000000000009670 .start_here_common+0x1c/0x2c

This is

        BUG_ON(limit && goal + size > limit);

and after some debugging, it seems that

	goal = 0x7ffff000000
	limit = 0x80000000000

and sparse_early_usemaps_alloc_node ->
sparse_early_usemaps_alloc_pgdat_section calls

	return alloc_bootmem_section(usemap_size() * count, section_nr);

This is on a system with 8TB available via the AMS pool, and as a quirk
of AMS in firmware, all of that memory shows up in node 0.  So, we end
up with an allocation that will fail the goal/limit constraints.

In theory, we could "fall-back" to alloc_bootmem_node() in
sparse_early_usemaps_alloc_node(), but since we actually have HOTREMOVE
defined, we'll BUG_ON() instead.  A simple solution appears to be to
unconditionally remove the limit condition in alloc_bootmem_section,
meaning allocations are allowed to cross section boundaries (necessary
for systems of this size).

Johannes Weiner pointed out that if alloc_bootmem_section() no longer
guarantees section-locality, we need check_usemap_section_nr() to print
possible cross-dependencies between node descriptors and the usemaps
allocated through it.  That makes the two loops in
sparse_early_usemaps_alloc_node() identical, so re-factor the code a
bit.

Subject: [PATCH 6174/6423] hugetlbfs: avoid taking i_mutex from
 hugetlbfs_read()

Taking i_mutex in hugetlbfs_read() can result in deadlock with mmap as
explained below

 Thread A:
  read() on hugetlbfs
   hugetlbfs_read() called
    i_mutex grabbed
     hugetlbfs_read_actor() called
      __copy_to_user() called
       page fault is triggered
 Thread B, sharing address space with A:
  mmap() the same file
   ->mmap_sem is grabbed on task_B->mm->mmap_sem
    hugetlbfs_file_mmap() is called
     attempt to grab ->i_mutex and block waiting for A to give it up
 Thread A:
  pagefault handled blocked on attempt to grab task_A->mm->mmap_sem,
 which happens to be the same thing as task_B->mm->mmap_sem.  Block waiting
 for B to give it up.

AFAIU the i_mutex locking was added to hugetlbfs_read() as per
http://lkml.indiana.edu/hypermail/linux/kernel/0707.2/3066.html to take
care of the race between truncate and read.  This patch fixes this by
looking at page->mapping under lock_page() (find_lock_page()) to ensure
that the inode didn't get truncated in the range during a parallel read.

Ideally we can extend the patch to make sure we don't increase i_size in
mmap.  But that will break userspace, because applications will now have
to use truncate(2) to increase i_size in hugetlbfs.

Based on the original patch from Hillf Danton.

The root cause is, the dirty threshold is knocked down a lot by the memory
hog task.  Fixed by using global_dirty_limit which decreases gradually on
such events and can guarantee we stay above (the also decreasing) nr_dirty
in the progress of following down to the new dirty threshold.

Subject: [PATCH 6177/6423] mm: update stale lock ordering comment for
 memory-failure.c

When i_mmap_lock changed to a mutex the locking order in memory failure
was changed to take the sleeping lock first.  But the big fat mm lock
ordering comment (BFMLO) wasn't updated.  Do this here.

Pointed out by Andrew.

Subject: [PATCH 6179/6423] mm, memcg: pass charge order to oom killer

The oom killer typically displays the allocation order at the time of oom
as a part of its diangostic messages (for global, cpuset, and mempolicy
ooms).

The memory controller may also pass the charge order to the oom killer so
it can emit the same information.  This is useful in determining how large
the memory allocation is that triggered the oom killer.

Subject: [PATCH 6180/6423] cpuset: mm: reduce large amounts of memory barrier
 related damage v3

Commit c0ff7453bb5c ("cpuset,mm: fix no node to alloc memory when
changing cpuset's mems") wins a super prize for the largest number of
memory barriers entered into fast paths for one commit.

[get|put]_mems_allowed is incredibly heavy with pairs of full memory
barriers inserted into a number of hot paths.  This was detected while
investigating at large page allocator slowdown introduced some time
after 2.6.32.  The largest portion of this overhead was shown by
oprofile to be at an mfence introduced by this commit into the page
allocator hot path.

For extra style points, the commit introduced the use of yield() in an
implementation of what looks like a spinning mutex.

This patch replaces the full memory barriers on both read and write
sides with a sequence counter with just read barriers on the fast path
side.  This is much cheaper on some architectures, including x86.  The
main bulk of the patch is the retry logic if the nodemask changes in a
manner that can cause a false failure.

While updating the nodemask, a check is made to see if a false failure
is a risk.  If it is, the sequence number gets bumped and parallel
allocators will briefly stall while the nodemask update takes place.

In a page fault test microbenchmark, oprofile samples from
__alloc_pages_nodemask went from 4.53% of all samples to 1.15%.  The
actual results were

    Total Elapsed Time (seconds)                123.46    120.87

The overall improvement is small but the System CPU time is much
improved and roughly in correlation to what oprofile reported (these
performance figures are without profiling so skew is expected).  The
actual number of page faults is noticeably improved.

For benchmarks like kernel builds, the overall benefit is marginal but
the system CPU time is slightly reduced.

To test the actual bug the commit fixed I opened two terminals.  The
first ran within a cpuset and continually ran a small program that
faulted 100M of anonymous data.  In a second window, the nodemask of the
cpuset was continually randomised in a loop.

Without the commit, the program would fail every so often (usually
within 10 seconds) and obviously with the commit everything worked fine.
With this patch applied, it also worked fine so the fix should be
functionally equivalent.

Subject: [PATCH 6182/6423] hugetlb: cleanup hugetlb.h

Make a couple of small cleanups to linux/include/hugetlb.h.  The
set_file_hugepages() function, which was not used anywhere is removed,
and the hugetlbfs_config and hugetlbfs_inode_info structures with its
HUGETLBFS_I helper function are moved into inode.c, the only place they
were used.

These structures are really linked to the hugetlbfs filesystem
specifically not to hugepage mm handling in general, so they belong in
the filesystem code not in a generally available header.

It would be nice to move the hugetlbfs_sb_info (superblock) structure in
there as well, but it's currently needed in a number of places via the
hstate_vma() and hstate_inode().

Subject: [PATCH 6183/6423] hugepages: fix use after free bug in "quota"
 handling

hugetlbfs_{get,put}_quota() are badly named.  They don't interact with the
general quota handling code, and they don't much resemble its behaviour.
Rather than being about maintaining limits on on-disk block usage by
particular users, they are instead about maintaining limits on in-memory
page usage (including anonymous MAP_PRIVATE copied-on-write pages)
associated with a particular hugetlbfs filesystem instance.

Worse, they work by having callbacks to the hugetlbfs filesystem code from
the low-level page handling code, in particular from free_huge_page().
This is a layering violation of itself, but more importantly, if the
kernel does a get_user_pages() on hugepages (which can happen from KVM
amongst others), then the free_huge_page() can be delayed until after the
associated inode has already been freed.  If an unmount occurs at the
wrong time, even the hugetlbfs superblock where the "quota" limits are
stored may have been freed.

Andrew Barry proposed a patch to fix this by having hugepages, instead of
storing a pointer to their address_space and reaching the superblock from
there, had the hugepages store pointers directly to the superblock,
bumping the reference count as appropriate to avoid it being freed.
Andrew Morton rejected that version, however, on the grounds that it made
the existing layering violation worse.

This is a reworked version of Andrew's patch, which removes the extra, and
some of the existing, layering violation.  It works by introducing the
concept of a hugepage "subpool" at the lower hugepage mm layer - that is a
finite logical pool of hugepages to allocate from.  hugetlbfs now creates
a subpool for each filesystem instance with a page limit set, and a
pointer to the subpool gets added to each allocated hugepage, instead of
the address_space pointer used now.  The subpool has its own lifetime and
is only freed once all pages in it _and_ all other references to it (i.e.
superblocks) are gone.

subpools are optional - a NULL subpool pointer is taken by the code to
mean that no subpool limits are in effect.

Previous discussion of this bug found in:  "Fix refcounting in hugetlbfs
quota handling.". See:  https://lkml.org/lkml/2011/8/11/28 or
http://marc.info/?l=linux-mm&m=126928970510627&w=1

v2: Fixed a bug spotted by Hillf Danton, and removed the extra parameter to
alloc_huge_page() - since it already takes the vma, it is not necessary.

Subject: [PATCH 6184/6423] mm, counters: remove task argument to sync_mm_rss()
 and __sync_task_rss_stat()

sync_mm_rss() can only be used for current to avoid race conditions in
iterating and clearing its per-task counters.  Remove the task argument
for it and its helper function, __sync_task_rss_stat(), to avoid thinking
it can be used safely for anything other than current.

Subject: [PATCH 6185/6423] mm, counters: fold __sync_task_rss_stat() into

There's no difference between sync_mm_rss() and __sync_task_rss_stat(),
so fold the latter into the former.

Subject: [PATCH 6186/6423] mm, hugetlb: add thread name and pid to SHM_HUGETLB
 mlock rlimit warning

Add the thread name and pid of the application that is allocating shm
segments with MAP_HUGETLB without being a part of
/proc/sys/vm/hugetlb_shm_group or having CAP_IPC_LOCK.

This identifies the application so it may be fixed by avoiding using the
deprecated exception (see Documentation/feature-removal-schedule.txt).

Subject: [PATCH 6187/6423] hugetlbfs: fix alignment of huge page requests

When calling shmget() with SHM_HUGETLB, shmget aligns the request size to
PAGE_SIZE, but this is not sufficient.

Modify hugetlb_file_setup() to align requests to the huge page size, and
to accept an address argument so that all alignment checks can be
performed in hugetlb_file_setup(), rather than in its callers.  Change
newseg() and mmap_pgoff() to match the new prototype and eliminate a now
redundant alignment check.

Subject: [PATCH 6194/6423] mm: forbid lumpy-reclaim in shrink_active_list()

Reset the reclaim mode in shrink_active_list() to RECLAIM_MODE_SINGLE |
RECLAIM_MODE_ASYNC.  (sync/async sign is used only in shrink_page_list
and does not affect shrink_active_list)

Currenly shrink_active_list() sometimes works in lumpy-reclaim mode, if
RECLAIM_MODE_LUMPYRECLAIM is left over from an earlier
shrink_inactive_list().  Meanwhile, in age_active_anon()
sc->reclaim_mode is totally zero.  So the current behavior is too
complex and confusing, and this looks like bug.

In general, shrink_active_list() populates the inactive list for the
next shrink_inactive_list().  Lumpy shring_inactive_list() isolates
pages around the chosen one from both the active and inactive lists.
So, there is no reason for lumpy isolation in shrink_active_list().

Subject: [PATCH 6195/6423] swap: don't do discard if no discard option added

When swapon() was not passed the SWAP_FLAG_DISCARD option, sys_swapon()
will still perform a discard operation.  This can cause problems if
discard is slow or buggy.

Reverse the order of the check so that a discard operation is performed
only if the sys_swapon() caller is attempting to enable discard.

Subject: [PATCH 6198/6423] memcg: lru_size instead of MEM_CGROUP_ZSTAT

I never understood why we need a MEM_CGROUP_ZSTAT(mz, idx) macro to
obscure the LRU counts.  For easier searching? So call it lru_size
rather than bare count (lru_length sounds better, but would be wrong,
since each huge page raises lru_size hugely).

Subject: [PATCH 6201/6423] memcg: remove unnecessary thp check in page stat
 accounting

Commit e94c8a9cbce1 ("memcg: make mem_cgroup_split_huge_fixup() more
efficient") removed move_lock_page_cgroup().  So we do not have to check
PageTransHuge in mem_cgroup_update_page_stat() and fallback into the
locked accounting because both move_account() and thp split are done
with compound_lock so they cannot race.

The race between update vs.  move is protected by mem_cgroup_stealed.

PageTransHuge pages shouldn't appear in this code path currently because
we are tracking only file pages at the moment but later we are planning
to track also other pages (e.g.  mlocked ones).

Make one small adjustment to idr_get_next(): take the height from the top
layer (stable under RCU) instead of from the root (unprotected by RCU), as
idr_find() does: so that it can be used with RCU locking.  Copied comment
on RCU locking from idr_find().

Subject: [PATCH 6203/6423] cgroup: revert ss_id_lock to spinlock

Commit c1e2ee2dc436 ("memcg: replace ss->id_lock with a rwlock") has now
been seen to cause the unfair behavior we should have expected from
converting a spinlock to an rwlock: softlockup in cgroup_mkdir(), whose
get_new_cssid() is waiting for the wlock, while there are 19 tasks using
the rlock in css_get_next() to get on with their memcg workload (in an
artificial test, admittedly).  Yet lib/idr.c was made suitable for RCU
way back: revert that commit, restoring ss->id_lock to a spinlock.

Remove lock and unlock around css_get_next()'s call to idr_get_next().
memcg iterators (only users of css_get_next) already did rcu_read_lock(),
and its comment demands that; but add a WARN_ON_ONCE to make sure of it.

Subject: [PATCH 6205/6423] memcg: remove PCG_CACHE page_cgroup flag

We record 'the page is cache' with the PCG_CACHE bit in page_cgroup.
Here, "CACHE" means anonymous user pages (and SwapCache).  This doesn't
include shmem.

Considering callers, at charge/uncharge, the caller should know what the
page is and we don't need to record it by using one bit per page.

This patch removes PCG_CACHE bit and make callers of
mem_cgroup_charge_statistics() to specify what the page is.

About page migration: Mapping of the used page is not touched during migra
tion (see page_remove_rmap) so we can rely on it and push the correct
charge type down to __mem_cgroup_uncharge_common from end_migration for
unused page.  The force flag was misleading was abused for skipping the
needless page_mapped() / PageCgroupMigration() check, as we know the
unused page is no longer mapped and cleared the migration flag just a few
lines up.  But doing the checks is no biggie and it's not worth adding
another flag just to skip them.

Subject: [PATCH 6208/6423] memcg: simplify move_account() check

In memcg, for avoiding take-lock-irq-off at accessing page_cgroup, a
logic, flag + rcu_read_lock(), is used.  This works as following

     CPU-A                     CPU-B
                             rcu_read_lock()
    set flag
                             if(flag is set)
                                   take heavy lock
                             do job.
    synchronize_rcu()        rcu_read_unlock()
    take heavy lock.

In recent discussion, it's argued that using per-cpu value for this flag
just complicates the code because 'set flag' is very rare.

This patch changes 'flag' implementation from percpu to atomic_t.  This
will be much simpler.

Subject: [PATCH 6209/6423] memcg: remove PCG_MOVE_LOCK flag from page_cgroup

PCG_MOVE_LOCK is used for bit spinlock to avoid race between overwriting
pc->mem_cgroup and page statistics accounting per memcg.  This lock helps
to avoid the race but the race is very rare because moving tasks between
cgroup is not a usual job.  So, it seems using 1bit per page is too
costly.

This patch changes this lock as per-memcg spinlock and removes
PCG_MOVE_LOCK.

If smaller lock is required, we'll be able to add some hashes but I'd like
to start from this.

Subject: [PATCH 6210/6423] memcg: use new logic for page stat accounting

Now, page-stat-per-memcg is recorded into per page_cgroup flag by
duplicating page's status into the flag.  The reason is that memcg has a
feature to move a page from a group to another group and we have race
between "move" and "page stat accounting",

Under current logic, assume CPU-A and CPU-B.  CPU-A does "move" and CPU-B
does "page stat accounting".

When CPU-A goes 1st,

            CPU-A                           CPU-B
                                    update "struct page" info.
    move_lock_mem_cgroup(memcg)
    see pc->flags
    copy page stat to new group
    overwrite pc->mem_cgroup.
    move_unlock_mem_cgroup(memcg)
                                    move_lock_mem_cgroup(mem)
                                    set pc->flags
                                    update page stat accounting
                                    move_unlock_mem_cgroup(mem)

stat accounting is guarded by move_lock_mem_cgroup() and "move" logic
(CPU-A) doesn't see changes in "struct page" information.

But it's costly to have the same information both in 'struct page' and
'struct page_cgroup'.  And, there is a potential problem.

For example, assume we have PG_dirty accounting in memcg.
PG_..is a flag for struct page.
PCG_ is a flag for struct page_cgroup.
(This is just an example. The same problem can be found in any
 kind of page stat accounting.)

	  CPU-A                               CPU-B
      TestSet PG_dirty
      (delay)                        TestClear PG_dirty
                                     if (TestClear(PCG_dirty))
                                          memcg->nr_dirty--
      if (TestSet(PCG_dirty))
          memcg->nr_dirty++

Here, memcg->nr_dirty = +1, this is wrong.  This race was reported by Greg
Thelen <gthelen@google.com>.  Now, only FILE_MAPPED is supported but
fortunately, it's serialized by page table lock and this is not real bug,
_now_,

If this potential problem is caused by having duplicated information in
struct page and struct page_cgroup, we may be able to fix this by using
original 'struct page' information.  But we'll have a problem in "move
account"

Assume we use only PG_dirty.

         CPU-A                   CPU-B
    TestSet PG_dirty
    (delay)                    move_lock_mem_cgroup()
                               if (PageDirty(page))
                                      new_memcg->nr_dirty++
                               pc->mem_cgroup = new_memcg;
                               move_unlock_mem_cgroup()
    move_lock_mem_cgroup()
    memcg = pc->mem_cgroup
    new_memcg->nr_dirty++

accounting information may be double-counted.  This was original reason to
have PCG_xxx flags but it seems PCG_xxx has another problem.

I think we need a bigger lock as

     move_lock_mem_cgroup(page)
     TestSetPageDirty(page)
     update page stats (without any checks)
     move_unlock_mem_cgroup(page)

This fixes both of problems and we don't have to duplicate page flag into
page_cgroup.  Please note: move_lock_mem_cgroup() is held only when there
are possibility of "account move" under the system.  So, in most path,
status update will go without atomic locks.

This patch introduces mem_cgroup_begin_update_page_stat() and
mem_cgroup_end_update_page_stat() both should be called at modifying
'struct page' information if memcg takes care of it.  as

     mem_cgroup_begin_update_page_stat()
     modify page information
     mem_cgroup_update_page_stat()
     => never check any 'struct page' info, just update counters.
     mem_cgroup_end_update_page_stat().

This patch is slow because we need to call begin_update_page_stat()/
end_update_page_stat() regardless of accounted will be changed or not.  A
following patch adds an easy optimization and reduces the cost.

Subject: [PATCH 6212/6423] memcg: fix performance of
 mem_cgroup_begin_update_page_stat()

mem_cgroup_begin_update_page_stat() should be very fast because it's
called very frequently.  Now, it needs to look up page_cgroup and its
memcg....this is slow.

This patch adds a global variable to check "any memcg is moving or not".
With this, the caller doesn't need to visit page_cgroup and memcg.

Here is a test result.  A test program makes page faults onto a file,
MAP_SHARED and makes each page's page_mapcount(page) > 1, and free the
range by madvise() and page fault again.  This program causes 26214400
times of page fault onto a file(size was 1G.) and shows shows the cost of
mem_cgroup_begin_update_page_stat().

Before this patch for mem_cgroup_begin_update_page_stat()

    [kamezawa@bluextal test]$ time ./mmap 1G

    real    0m21.765s
    user    0m5.999s
    sys     0m15.434s

    27.46%     mmap  mmap               [.] reader
    21.15%     mmap  [kernel.kallsyms]  [k] page_fault
     9.17%     mmap  [kernel.kallsyms]  [k] filemap_fault
     2.96%     mmap  [kernel.kallsyms]  [k] __do_fault
     2.83%     mmap  [kernel.kallsyms]  [k] __mem_cgroup_begin_update_page_stat

After this patch

    [root@bluextal test]# time ./mmap 1G

    real    0m21.373s
    user    0m6.113s
    sys     0m15.016s

In usual path, calls to __mem_cgroup_begin_update_page_stat() goes away.

Note: we may be able to remove this optimization in future if
      we can get pointer to memcg directly from struct page.

Subject: [PATCH 6216/6423] memcg: clean up existing move charge code

- Replace lengthy function name is_target_pte_for_mc() with a shorter
  one in order to avoid ugly line breaks.

- explicitly use MC_TARGET_* instead of simply using integers.

 !CONFIG_TRANSPARENT_HUGEPAGE

These macros will be used in a later patch, where all usages are expected
to be optimized away without #ifdef CONFIG_TRANSPARENT_HUGEPAGE.  But to
detect unexpected usages, we convert the existing BUG() to BUILD_BUG().

Subject: [PATCH 6218/6423] memcg: avoid THP split in task migration

Currently we can't do task migration among memory cgroups without THP
split, which means processes heavily using THP experience large overhead
in task migration.  This patch introduces the code for moving charge of
THP and makes THP more valuable.

Subject: [PATCH 6221/6423] tg3: Fix RSS ring refill race condition

The RSS feature in tg3 hardware has only one rx producer ring for all
RSS rings.  NAPI vector 1 is special and handles the refilling of the
rx producer ring on behalf of all RSS rings.  There is a race condition
between these RSS NAPIs and the NAPI[1].  If NAPI[1] finishes checking
for refill and then another RSS ring empties the rx producer ring
before NAPI[1] exits NAPI, the chip will be completely out of SKBs in
the rx producer ring.

We fix this by adding a flag tp->rx_refill and rely on napi_schedule()/
napi_complete() to help synchronize it to close the race condition.

Update driver version to 3.123.

Subject: [PATCH 6222/6423] cnic: Fix parity error code conflict

The recently added parity error handling used an error code that was
already defined for a different error.  This could lead to bnx2x
firmware assert.  We need to fix this with new error codes that are
defined for parity error only.

Subject: [PATCH 6223/6423] l2tp: enable automatic module loading for l2tp_ppp

When L2TP is configured as a module, requests for L2TP sockets do not result
in the l2tp_ppp module being loaded.  Fix this by adding the appropriate
MODULE_ALIAS to be recognized by pppox's request_module() call.

Subject: [PATCH 6224/6423] drm/nouveau/ttm: always do buffer moves on kernel
 channel

There was once good reasons for wanting the drm to be able to use M2MF etc
on user channels, but they're not relevant anymore.  For the general
buffer move case, we've already lost by transferring between vram/sysmem
already so the context switching overhead is minimal in comparison.

Subject: [PATCH 6226/6423] drm/nouveau: move fence sequence check to start of
 loop

I want to be able to use REF_CNT from other places in the kernel without
pushing a fence object onto the list of emitted fences.

The current code makes an assumption that every time the acked sequence is
bumped that there's at least one fence on the list that'll be signalled.

This will no longer be true in the near future.

Subject: [PATCH 6229/6423] drm/nouveau: inform userspace of new kernel
 subchannel requirements

All available subchannels are now available for userspace to do with as it
pleases on NVC0+.

On all earlier chipsets, the kernel still uses a software object on subc 0
to implement the page flip completion method.  I hope to find some decent
way of addressing this too, but it's a tad tricker prior to fermi.

Subject: [PATCH 6232/6423] drm/nouveau: bump version to 1.0.0

The time has come to get a proper version number that we can change to
indicate new features etc, rather than the lock-step 0.0.XX that we
previously had.

libdrm has recognised this version as compatible with 0.0.16 since 2.4.22,
so hopefully any breakage people see should be very minimal.

Subject: [PATCH 6239/6423] xen: initialize platform-pci even if
 xen_emul_unplug=never

When xen_emul_unplug=never is specified on kernel command line
reading files from /sys/hypervisor is broken (returns -EBUSY).
It is caused by xen_bus dependency on platform-pci and
platform-pci isn't initialized when xen_emul_unplug=never is
specified.

Fix it by allowing platform-pci to ignore xen_emul_unplug=never,
and do not intialize xen_[blk|net]front instead.

Subject: [PATCH 6242/6423] x86, boot: Correct CFLAGS for hostprogs

This is a partial revert of commit:
    d40f833 "Restrict CFLAGS for hostprogs"

The endian-manipulation macros in tools/include need <linux/types.h>,
but the hostprogs in arch/x86/boot need several headers from the
kernel build tree, which means we have to add the kernel headers to
the include path.  This picks up <linux/types.h> from the kernel tree,
which gives a warning.

Since this use of <linux/types.h> is intentional, add
-D__EXPORTED_HEADERS__ to the command line to silence the warning.

A better way to fix this would be to always install the exported
kernel headers into $(objtree)/usr/include as a standard part of the
kernel build, but that is a lot more involved.

Subject: [PATCH 6245/6423] kgdb,debug-core,gdbstub: Hook the reboot notifier
 for debugger detach

The gdbstub and kdb should get detached if the system is rebooting.
Calling gdbstub_exit() will set the proper debug core state and send a
message to any debugger that is connected to correctly detach.

An attached debugger will receive the exit code from
include/linux/reboot.h based on SYS_HALT, SYS_REBOOT, etc...

Subject: [PATCH 6246/6423] KDB: Fix usability issues relating to the 'enter'
 key.

This fixes the following problems:
1) Typematic-repeat of 'enter' gives warning message
   and leaks make/break if KDB exits. Repeats
   look something like 0x1c 0x1c .... 0x9c
2) Use of 'keypad enter' gives warning message and
   leaks the ENTER break/make code out if KDB exits.
   KP ENTER repeats look someting like 0xe0 0x1c
   0xe0 0x1c ... 0xe0 0x9c.
3) Lag on the order of seconds between "break" and "make" when
   expecting the enter "break" code. Seen under virtualized
   environments such as VMware ESX.

The existing special enter handler tries to glob the enter break code,
but this fails if the other (KP) enter was used, or if there was a key
repeat. It also fails if you mashed some keys along with enter, and
you ended up with a non-enter make or non-enter break code coming
after the enter make code. So first, we modify the handler to handle
these cases. But performing these actions on every enter is annoying
since now you can't hold ENTER down to scroll <more>d messages in
KDB. Since this special behaviour is only necessary to handle the
exiting KDB ('g' + ENTER) without leaking scancodes to the OS.  This
cleanup needs to get executed anytime the kdb_main loop exits.

Tested on QEMU. Set a bp on atkbd.c to verify no scan code was leaked.

Subject: [PATCH 6247/6423] kgdb,debug_core: add the ability to control the
 reboot notifier

Sometimes it is desirable to stop the kernel debugger before allowing
a system to reboot either with kdb or kgdb.  This patch adds the
ability to turn the reboot notifier on and off or enter the debugger
and stop kernel execution before rebooting.

It is possible to change the setting after booting the kernel with the
following:

echo 1 > /sys/module/debug_core/parameters/kgdbreboot

It is also possible to change this setting using kdb / kgdb to
manipulate the variable directly.

Using KDB:
   mm kgdbreboot 1

Using gdb:
   set kgdbreboot=1

This fixes a bug with setting a breakpoint during kdb initialization
(from kdb_cmds).  Any call to kdb_printf() before the initialization
of the kgdboc serial console driver (which happens much later during
bootup than kdb_init), results in kernel panic due to the use of
dbg_io_ops before it is initialized.

On x86, if CONFIG_DEBUG_RODATA is set, one cannot set breakpoints
via KDB.  Apparently this is a well-known problem, as at least one distribution
now ships with both KDB enabled and CONFIG_DEBUG_RODATA=y for security reasons.

This patch adds an printk message to the breakpoint failure case,
in order to provide suggestions about how to use the debugger.

Subject: [PATCH 6250/6423] x86-32: Fix endless loop when processing signals
 for kernel tasks

The problem occurs on !CONFIG_VM86 kernels [1] when a kernel-mode task
returns from a system call with a pending signal.

A real-life scenario is a child of 'khelper' returning from a failed
kernel_execve() in ____call_usermodehelper() [ kernel/kmod.c ].
kernel_execve() fails due to a pending SIGKILL, which is the result of
"kill -9 -1" (at least, busybox's init does it upon reboot).

The loop is as follows:

* syscall_exit_work:
 - work_pending:            // start_of_the_loop
 - work_notify_sig:
   - do_notify_resume()
     - do_signal()
       - if (!user_mode(regs)) return;
 - resume_userspace         // TIF_SIGPENDING is still set
 - work_pending             // so we call work_pending => goto
                            // start_of_the_loop

More information can be found in another LKML thread:
http://www.serverphorums.com/read.php?12,457826

[1] the problem was also seen on MIPS.

Subject: [PATCH 6251/6423] sysctl: protect poll() in entries that may go away

Protect code accessing ctl_table by grabbing the header with grab_header()
and after releasing with sysctl_head_finish().  This is needed if poll()
is called in entries created by modules: currently only hostname and
domainname support poll(), but this bug may be triggered when/if modules
use it and if user called poll() in a file that doesn't support it.

Dave Jones reported the following when using a syscall fuzzer while
hibernating/resuming:

RIP: 0010:[<ffffffff81233e3e>]  [<ffffffff81233e3e>] proc_sys_poll+0x4e/0x90
RAX: 0000000000000145 RBX: ffff88020cab6940 RCX: 0000000000000000
RDX: ffffffff81233df0 RSI: 6b6b6b6b6b6b6b6b RDI: ffff88020cab6940
[ ... ]
Code: 00 48 89 fb 48 89 f1 48 8b 40 30 4c 8b 60 e8 b8 45 01 00 00 49 83
7c 24 28 00 74 2e 49 8b 74 24 30 48 85 f6 74 24 48 85 c9 75 32 <8b> 16
b8 45 01 00 00 48 63 d2 49 39 d5 74 10 8b 06 48 98 48 89

If an entry goes away while we are polling() it, ctl_table may not exist
anymore.

While doing the fs/namei.c cleanups, I ran sparse on it, and it pointed
out other large integers and a couple of cases of us using '0' instead
of the proper 'NULL'.

Sparse still doesn't understand some of the conditional locking going
on, but that's no excuse for not fixing up the trivial stuff.

This function takes a GFP flags as a parameter, but they are never used.
We don't take a lock in this function so there is no reason to prefer
GFP_ATOMIC over the caller's GFP flags.

There is only one caller, cipso_v4_map_cat_rng_ntoh(), and it passes
GFP_ATOMIC as the GFP flags so this doesn't change how the code works.
It's just a cleanup.

Subject: [PATCH 6261/6423] usbnet: increase URB reference count before
 usb_unlink_urb

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock, but it makes usb_unlink_urb
racing with defer_bh, and the URB to being unlinked may be freed before
or during calling usb_unlink_urb, so use-after-free problem may be
triggerd inside usb_unlink_urb.

The patch fixes the use-after-free problem by increasing URB
reference count with skb queue lock held before calling
usb_unlink_urb, so the URB won't be freed until return from
usb_unlink_urb.

Subject: [PATCH 6262/6423] usbnet: don't clear urb->dev in tx_complete

URB unlinking is always racing with its completion and tx_complete
may be called before or during running usb_unlink_urb, so tx_complete
must not clear urb->dev since it will be used in unlink path,
otherwise invalid memory accesses or usb device leak may be caused
inside usb_unlink_urb.

Subject: [PATCH 6263/6423] security: optimize avc_audit() common path

avc_audit() did a lot of jumping around and had a big stack frame, all
for the uncommon case.

Split up the uncommon case (which we really can't make go fast anyway)
into its own slow function, and mark the conditional branches
appropriately for the common likely case.

This causes avc_audit() to no longer show up as one of the hottest
functions on the branch profiles (the new "perf -b" thing), and makes
the cycle profiles look really nice and dense too.

The whole audit path is still annoyingly very much one of the biggest
costs of name lookup, so these things are worth optimizing for.  I wish
we could just tell people to turn it off, but realistically we do need
it: we just need to make sure that the overhead of the necessary evil is
as low as possible.

It used to be an int, and it got changed to a bool parameter at least
7 years ago.  It happens that NF_ACCEPT and NF_DROP are 0 and 1, so
this works, but it's unclear, and the check that it's in range is not
required.

Subject: [PATCH 6265/6423] bonding: remove entries for master_ip and vlan_ip
 and query devices instead

The following patch aimed to resolve an issue where secondary, tertiary,
etc. addresses added to bond interfaces could overwrite the
bond->master_ip and vlan_ip values.

        commit 917fbdb32f37e9a93b00bb12ee83532982982df3
        Author: Henrik Saavedra Persson <henrik.e.persson@ericsson.com>
        Date:   Wed Nov 23 23:37:15 2011 +0000

            bonding: only use primary address for ARP

That patch was good because it prevented bonds using ARP monitoring from
sending frames with an invalid source IP address.  Unfortunately, it
didn't always work as expected.

When using an ioctl (like ifconfig does) to set the IP address and
netmask, 2 separate ioctls are actually called to set the IP and netmask
if the mask chosen doesn't match the standard mask for that class of
address.  The first ioctl did not have a mask that matched the one in
the primary address and would still cause the device address to be
overwritten.  The second ioctl that was called to set the mask would
then detect as secondary and ignored, but the damage was already done.

This was not an issue when using an application that used netlink
sockets as the setting of IP and netmask came down at once.  The
inconsistent behavior between those two interfaces was something that
needed to be resolved.

While I was thinking about how I wanted to resolve this, Ralf Zeidler
came with a patch that resolved this on a RHEL kernel by keeping a full
shadow of the entries in dev->ifa_list for the bonding device and vlan
devices in the bonding driver.  I didn't like the duplication of the
list as I want to see the 'bonding' struct and code shrink rather than
grow, but liked the general idea.

As the Subject indicates this patch drops the master_ip and vlan_ip
elements from the 'bonding' and 'vlan_entry' structs, respectively.
This can be done because a device's address-list is now traversed to
determine the optimal source IP address for ARP requests and for checks
to see if the bonding device has a particular IP address.  This code
could have all be contained inside the bonding driver, but it made more
sense to me to EXPORT and call inet_confirm_addr since it did exactly
what was needed.

I tested this and a backported patch and everything works as expected.
Ralf also helped with verification of the backported patch.

Thanks to Ralf for all his help on this.

v2: Whitespace and organizational changes based on suggestions from Jay
Vosburgh and Dave Miller.

v3: Fixup incorrect usage of rcu_read_unlock based on Dave Miller's
suggestion.

so subdrivers need not worry. This hurts use cases which do
rx only or predominantly.

Subject: [PATCH 6267/6423] hwmon: (fam15h_power) Correct sign extension of
 running_avg_capture

Wrong bit was used for sign extension which caused wrong end results.
Thanks to Andre for spotting this bug.

Subject: [PATCH 6268/6423] hwmon: (fam15h_power) Increase output resolution

On high CPU load the accumulating values in the running_avg_cap
register are very low (below 10), so averaging them too early leads
to unnecessary poor output resolution. Since we pretend to output
micro-Watt we better keep all the bits we have as long as possible.

Subject: [PATCH 6269/6423] hwmon: (w83795) Unconditionally support manual fan
 speed control

Manual fan speed control uses a standard interface and has received
sufficient testing and review by now, it can be enabled
unconditionally. This includes attributes pwm[1-8], pwm[1-8]_enable,
pwm[1-8]_mode and pwm[1-8]_freq.

We only let the user switch from automatic mode to manual mode, but
not the other way around, as automatic control settings may not have
been set properly by the BIOS.

Subject: [PATCH 6273/6423] hwmon: (lm90) Restore original configuration if
 probe function fails

The lm90 driver restores the original chip configuration in its exit function.
However, the chip configuration is not restored if the probe function fails.
Restore it there as well.

Subject: [PATCH 6275/6423] hwmon: (lm63) Make fan speed control strategy
 changeable

Let the user switch between automatic and manual fan speed control.
Before switching to automatic fan speed control, we always check that
the lookup table looks sane.

Subject: [PATCH 6278/6423] hwmon: (mc13783-adc) Add support for the MC13892
 PMIC

Based on a patch by David Jander that mostly did s/mc13783/mc13xxx/ .

Additionally use dev_get_drvdata instead of to_platform_device +
platform_get_drvdata in mc13783_adc_read (spotted by Jean Delvare).

 Description
 -----------
 
-The Freescale MC13783 is a Power Management and Audio Circuit. Among
-other things it contains a 10-bit A/D converter. The converter has 16
-channels which can be used in different modes.
-The A/D converter has a resolution of 2.25mV. Channels 0-4 have
-a dedicated meaning with chip internal scaling applied. Channels 5-7
-can be used as general purpose inputs or alternatively in a dedicated
-mode. Channels 12-15 are occupied by the touchscreen if it's active.

Subject: [PATCH 6279/6423] hwmon: Add MCP3021 ADC driver

Add I2C driver for MCP3021 that is an ADC chip from Microchip.
The MCP3021 is a successive approximation A/D converter (ADC)
with 10-bit resolution.
The driver export the value of Vin to sysfs, the voltage unit is
mV. Through the sysfs interface, lm-sensors tool can also display
Vin voltage.

+Description
+-----------
+
+This driver implements support for the Microchip Technology MCP3021 chip.
+
+The Microchip Technology Inc. MCP3021 is a successive approximation A/D
+converter (ADC) with 10-bit resolution.
+This device provides one single-ended input with very low power consumption.
+Communication to the MCP3021 is performed using a 2-wire I2C compatible
+interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are available.
+The default I2C device address is 0x4d (contact the Microchip factory for
+additional address options).

Subject: [PATCH 6283/6423] um: use set_current_blocked() and block_sigmask()

As described in commit e6fa16ab9c1e ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures.  In the past some architectures got this code
wrong, so using this helper function should stop that from happening
again.

Subject: [PATCH 6285/6423] nmi watchdog: do not use cpp symbol in Kconfig

ARCH_HAS_NMI_WATCHDOG is a macro defined by arch, but config
HARDLOCKUP_DETECTOR depends on it.  This is wrong, ARCH_HAS_NMI_WATCHDOG
has to be a Kconfig config, and arch's need it should select it
explicitly.

This addresses some header check warnings.  DRM headers which include
"drm.h" have been excluded, as they indirectly include types.h.

Subject: [PATCH 6287/6423] consolidate WARN_...ONCE() static variables

Due to the alignment of following variables, these typically consume
more than just the single byte that 'bool' requires, and as there are a
few hundred instances, the cache pollution (not so much the waste of
memory) sums up.  Put these variables into their own section, outside of
any half way frequently used memory range.

Do the same also to the __warned variable of rcu_lockdep_assert().
(Don't, however, include the ones used by printk_once() and alike, as
they can potentially be hot.)

Subject: [PATCH 6290/6423] drivers/staging/telephony/ixj.c: fix warning about
 sequence points
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

In the statement

	j->caplist[j->caps].handle = j->caps++;

there is no sequence point between the usage of j->caps on the LHS of
the assignment and the incrementation on its RHS.  So it's not defined
in Standard C if j->caps is already incremented when used on the LHS
even though the postfix ++ operator is used.  To properly fix that the
incrementation has to be done in a separate expression.

This fixes:

From ebec18a6d3aa1e7d84aab16225e87fd25170ec2b Mon Sep 17 00:00:00 2001

Subject: [PATCH 6291/6423] prctl: add PR_{SET,GET}_CHILD_SUBREAPER to allow
 simple process supervision

Userspace service managers/supervisors need to track their started
services.  Many services daemonize by double-forking and get implicitly
re-parented to PID 1.  The service manager will no longer be able to
receive the SIGCHLD signals for them, and is no longer in charge of
reaping the children with wait().  All information about the children is
lost at the moment PID 1 cleans up the re-parented processes.

With this prctl, a service manager process can mark itself as a sort of
'sub-init', able to stay as the parent for all orphaned processes
created by the started services.  All SIGCHLD signals will be delivered
to the service manager.

Receiving SIGCHLD and doing wait() is in cases of a service-manager much
preferred over any possible asynchronous notification about specific
PIDs, because the service manager has full access to the child process
data in /proc and the PID can not be re-used until the wait(), the
service-manager itself is in charge of, has happened.

As a side effect, the relevant parent PID information does not get lost
by a double-fork, which results in a more elaborate process tree and
'ps' output:

before:
  # ps afx
  253 ?        Ss     0:00 /bin/dbus-daemon --system --nofork
  294 ?        Sl     0:00 /usr/libexec/polkit-1/polkitd
  328 ?        S      0:00 /usr/sbin/modem-manager
  608 ?        Sl     0:00 /usr/libexec/colord
  658 ?        Sl     0:00 /usr/libexec/upowerd
  819 ?        Sl     0:00 /usr/libexec/imsettings-daemon
  916 ?        Sl     0:00 /usr/libexec/udisks-daemon
  917 ?        S      0:00  \_ udisks-daemon: not polling any devices

after:
  # ps afx
  294 ?        Ss     0:00 /bin/dbus-daemon --system --nofork
  426 ?        Sl     0:00  \_ /usr/libexec/polkit-1/polkitd
  449 ?        S      0:00  \_ /usr/sbin/modem-manager
  635 ?        Sl     0:00  \_ /usr/libexec/colord
  705 ?        Sl     0:00  \_ /usr/libexec/upowerd
  959 ?        Sl     0:00  \_ /usr/libexec/udisks-daemon
  960 ?        S      0:00  |   \_ udisks-daemon: not polling any devices
  977 ?        Sl     0:00  \_ /usr/libexec/packagekitd

This prctl is orthogonal to PID namespaces.  PID namespaces are isolated
from each other, while a service management process usually requires the
services to live in the same namespace, to be able to talk to each
other.

Users of this will be the systemd per-user instance, which provides
init-like functionality for the user's login session and D-Bus, which
activates bus services on-demand.  Both need init-like capabilities to
be able to properly keep track of the services they start.

Many thanks to Oleg for several rounds of review and insights.

Subject: [PATCH 6292/6423] kernel/exit.c: if init dies, log a signal which
 killed it, if any

I just received another user's pleas for help when their init
mysteriously died.  I again explained that they need to check whether it
died because of bad instruction, a segv, or something else.  Which was
an annoying detour into writing a trivial C program to spawn his init
and print its exit code:

  http://lists.busybox.net/pipermail/busybox/2012-January/077172.html

I hear you saying "just test it under /bin/sh".  Well, the crashing init
_was_ /bin/sh.

Which prompted me to make kernel do this first step automatically.  We can
print exit code, which makes it possible to see that death was from e.g.
SIGILL without writing test programs.

bogus hardlockup detection.  This has been seen during LTP pounder test
executed in parallel with hotplug test.

The main problem is that enable_watchdog (called when CPU is brought up)
registers perf event which periodically checks per-cpu counter
(hrtimer_interrupts), updated from a hrtimer callback, but the hrtimer
is fired from the kernel thread.

This means that while we already do check for the hard lockup the kernel
thread might be sitting on the runqueue with zillions of tasks so there
is nobody to update the value we rely on and so we KABOOM.

Let's fix this by boosting the watchdog thread priority before we wake
it up rather than when it's already running.  This still doesn't handle
a case where we have the same amount of high prio FIFO tasks but that
doesn't seem to be common.  The current implementation doesn't handle
that case anyway so this is not worse at least.

Unfortunately, we cannot start perf counter from the watchdog thread
because we could miss a real lock up and also we cannot start the
hrtimer watchdog_enable because we there is no way (at least I don't
know any) to start a hrtimer from a different CPU.

From 1107d40a50956146d1272f5cffcdf1d83f7e703e Mon Sep 17 00:00:00 2001
From: Julia Lawall <Julia.Lawall@lip6.fr>
Date: Fri, 23 Mar 2012 15:02:00 -0700
Subject: [PATCH 6305/6423] drivers/video/backlight/wm831x_bl.c: use devm_
 functions

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

Subject: [PATCH 6307/6423] drivers/video/backlight/adp5520_bl.c: use devm_
 functions

The various devm_ functions allocate memory that is released when a driver
detaches.  This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.

Subject: [PATCH 6308/6423] backlight: new backlight driver for LP855x devices

THis driver supports TI LP8550/LP8551/LP8552/LP8553/LP8556 backlight
devices.

The brightness can be controlled by the I2C or PWM input.  The lp855x
driver provides both modes.  For the PWM control, pwm-specific functions
can be defined in the platform data.  And some information can be read
via the sysfs(lp855x device attributes).

For details, please refer to Documentation/backlight/lp855x-driver.txt.

+Kernel driver lp855x
+====================
+
+Backlight driver for LP855x ICs
+
+Supported chips:
+	Texas Instruments LP8550, LP8551, LP8552, LP8553 and LP8556
+
+Author: Milo(Woogyom) Kim <milo.kim@ti.com>
+
+Description
+-----------
+
+* Brightness control
+
+Brightness can be controlled by the pwm input or the i2c command.
+The lp855x driver supports both cases.
+
+* Device attributes
+
+1) bl_ctl_mode
+Backlight control mode.
+Value : pwm based or register based
+
+2) chip_id
+The lp855x chip id.
+Value : lp8550/lp8551/lp8552/lp8553/lp8556
+
+Platform data for lp855x
+------------------------
+
+For supporting platform specific data, the lp855x platform data can be used.
+
+* name : Backlight driver name. If it is not defined, default name is set.
+* mode : Brightness control mode. PWM or register based.
+* device_control : Value of DEVICE CONTROL register.
+* initial_brightness : Initial value of backlight brightness.
+* pwm_data : Platform specific pwm generation functions.
+	     Only valid when brightness is pwm input mode.
+	     Functions should be implemented by PWM driver.
+	     - pwm_set_intensity() : set duty of PWM
+	     - pwm_get_intensity() : get current duty of PWM
+* load_new_rom_data :
+	0 : use default configuration data
+	1 : update values of eeprom or eprom registers on loading driver
+* size_program : Total size of lp855x_rom_data.
+* rom_data : List of new eeprom/eprom registers.
+
+example 1) lp8552 platform data : i2c register mode with new eeprom data
+
+#define EEPROM_A5_ADDR	0xA5
+#define EEPROM_A5_VAL	0x4f	/* EN_VSYNC=0 */
+
+static struct lp855x_rom_data lp8552_eeprom_arr[] = {

+	.load_new_rom_data = 1,
+	.size_program = ARRAY_SIZE(lp8552_eeprom_arr),
+	.rom_data = lp8552_eeprom_arr,
+};
+
+example 2) lp8556 platform data : pwm input mode with default rom data
+
+static struct lp855x_platform_data lp8556_pdata = {
+	.mode = PWM_BASED,
+	.device_control = PWM_CONFIG(LP8556),

Subject: [PATCH 6310/6423] backlight: add support for Pandora backlight

Add support for pandora (openpandora.org) backlight.

It might look like all this could be done using pwm_bl.c instead, but
there is a need of special programming sequence when turning on the LED
driver chip or else it will misbehave.  Doing this using pwm_bl.c would
require to use some register programming and pwm functions from platform
code, and ARM maintainers are allergic to driver-like code in /arch/arm
nowadays.  The PMIC PWM driver is currently missing too, so pwm_bl.c
can't be used anyway.

Subject: [PATCH 6313/6423] bitops: rename for_each_set_bit_cont() in favor of
 analogous list.h function

This renames for_each_set_bit_cont() to for_each_set_bit_from() because
it is analogous to list_for_each_entry_from() in list.h rather than
list_for_each_entry_continue().

This doesn't remove for_each_set_bit_cont() for now.

Subject: [PATCH 6321/6423] drivers/leds/leds-tca6507.c: cleanup error handling
 in tca6507_probe()

Just a small tidy-up.

1) There is a NULL dereference if the tca allocation fails.
2) The call to cancel_work_sync() isn't needed because we haven't
   scheduled any work.
3) The call to i2c_set_clientdata() isn't needed because the core
   handles that automatically if probe() fails.
4) I added some curly braces for style reasons.

Subject: [PATCH 6325/6423] drivers/leds/leds-lp5521.c: support led pattern
 data

The lp5521 has autonomous operation mode without external control.
Using lp5521_platform_data, various led patterns can be configurable.
For supporting this feature, new functions and device attribute are
added.

Structure of lp5521_led_pattern: 3 channels are supported - red, green
and blue.  Pattern(s) of each channel and numbers of pattern(s) are
defined in the pla= tform data.  Pattern data are hexa codes which
include pattern commands such like set pwm, wait, ramp up/down, branch
and so on.

Pattern mode functions:
 * lp5521_clear_program_memory
	Before running new led pattern, program memory should be cleared.
 * lp5521_write_program_memory
	Pattern data updated in the program memory via the i2c.
 * lp5521_get_pattern
	Get pattern from predefined in the platform data.
 * lp5521_run_led_pattern
	Stop current pattern or run new pattern.
	Transition time is required between different operation mode.

Device attribute - 'led_pattern': To load specific led pattern, new device
attribute is added.

When the lp5521 driver is unloaded, stop current led pattern mode.

Documentation updated : description about how to define the led patterns
and example.

Subject: [PATCH 6326/6423] drivers/leds/leds-lp5521.c: redefinition of
 register bits

For better readability, values of LP5521_REG_ENABLE register were
redefined= .  Additional definitions: LP5521_ENABLE_DEFAULT and
LP5521_ENABLE_RUN_PROGRAM= .

Use definition rather than hard code value.
: 0x3F -> 'LP5521_CMD_DIRECT'

Subject: [PATCH 6331/6423] leds-lm3530: set the max_brightness to 127

Only 7 bits are used for updating the brightness.  (register address :
A0h) So the max_brightness property of lm3530 should be set to 127.

On initializing registers, maximum initial brightness is limited to
'max_brightness'.

Division-by-two is removed on updating the brightness.  This arithmetic is
not necessary because the range of brightness is 0 ~ 127= .

Subject: [PATCH 6333/6423] leds-lm3530: support pwm input mode

* add 'struct lm3530_pwm_data' in the platform data
  The pwm data is the platform specific functions which generate the pwm.
  The pwm data is only valid when brightness is pwm input mode.
  Functions should be implemented by the pwm driver.
  pwm_set_intensity() : set duty of pwm.
  pwm_get_intensity() : get current the brightness.

* brightness control by pwm
  If the control mode is pwm, then brightness is changed by the duty of
  pwm=.  So pwm platform function should be called in lm3530_brightness_set().

* do not update brightness register when pwm input mode
  In pwm input mode, brightness register is not used.
  If any value is updated in this register, then the led will be off.

* when input mode is changed, set duty of pwm to 0 if unnecessary.

Subject: [PATCH 6339/6423] string: memchr_inv() speed improvements

- Generate a 64-bit pattern more efficiently

memchr_inv needs to generate a 64-bit pattern filled with a target
character.  The operation can be done by more efficient way.

- Don't call the slow check_bytes() if the memory area is 64-bit aligned

memchr_inv compares contiguous 64-bit words with the 64-bit pattern as
much as possible.  The outside of the region is checked by check_bytes()
that scans for each byte.  Unfortunately, the first 64-bit word is
unexpectedly scanned by check_bytes() even if the memory area is aligned
to a 64-bit boundary.

Both changes were originally suggested by Eric Dumazet.

In current code, the deleted-node is recorded from first to last,
actually, we can directly attach these node on 'node' we will insert as
the left child, it can let the code more readable.

Subject: [PATCH 6345/6423] checkpatch: add some --strict coding style checks

Argument alignment across multiple lines should match the open
parenthesis.

Logical continuations should be at the end of the previous line, not the
start of a new line.

These are not required by CodingStyle so make the tests active only when
using --strict.

Improved by some examples from Bruce Allen.

Subject: [PATCH 6346/6423] checkpatch.pl: be silent when -q and --ignore is
 given

Fix checkpatch.pl when both -q and --ignore are given and prevents it from
printing a

NOTE: Ignored message types: blah

messages.

E.g., if I use -q --ignore PREFER_PACKED,PREFER_ALIGNED, i see:

NOTE: Ignored message types: PREFER_ALIGNED PREFER_PACKED

It makes no sense to print this when -q is given.

With any very high precedence operator it is not necessary to enforce

us requesting further perentheses around the following:

    #define PMEM_IS_FREE(id, index) !(pmem[id].bitmap[index].allocated)

For now add logical and bitwise not and unary minus.

Subject: [PATCH 6355/6423] checkpatch: check for quoted strings broken across
 lines

checkpatch already makes an exception to the 80-column rule for quoted
strings, and Documentation/CodingStyle recommends not splitting quoted
strings across lines, because it breaks the ability to grep for the
string.  Rather than just permitting this, actively warn about quoted
strings split across lines.

Test case:

void context(void)
{
	struct { unsigned magic; const char *strdata; } foo[] = {
		{ 42, "these strings"
		      "do not produce warnings" },
		{ 256, "though perhaps"
		       "they should" },
	};
	pr_err("this string"
	       " should produce a warning\n");
	pr_err("this multi-line string\n"
	       "should not produce a warning\n");
	asm ("this asm\n\t"
	     "should not produce a warning");
}

Results of checkpatch on that test case:

WARNING: quoted string split across lines
+	       " should produce a warning\n");

total: 0 errors, 1 warnings, 15 lines checked

Date: Fri, 23 Mar 2012 15:02:21 -0700
Subject: [PATCH 6356/6423] crc32: remove two instances of trailing whitespaces

This patchset (re)uses Bob Pearson's crc32 slice-by-8 code to stamp out
a software crc32c implementation.  It removes the crc32c implementation
in crypto/ in favor of using the stamped-out one in lib/.  There is also
a change to Kconfig so that the kernel builder can pick an
implementation best suited for the hardware.

The motivation for this patchset is that I am working on adding full
metadata checksumming to ext4.  As far as performance impact of adding
checksumming goes, I see nearly no change with a standard mail server
ffsb simulation.  On a test that involves only file creation and
deletion and extent tree writes, I see a drop of about 50 pcercent with
the current kernel crc32c implementation; this improves to a drop of
about 20 percent with the enclosed crc32c code.

When metadata is usually a small fraction of total IO, this new
implementation doesn't help much because metadata is usually a small
fraction of total IO.  However, when we are doing IO that is almost all
metadata (such as rm -rf'ing a tree), then this patch speeds up the
operation substantially.

Incidentally, given that iscsi, sctp, and btrfs also use crc32c, this
patchset should improve their speed as well.  I have not yet quantified
that, however.  This latest submission combines Bob's patches from late
August 2011 with mine so that they can be one coherent patch set.
Please excuse my inability to combine some of the patches; I've been
advised to leave Bob's patches alone and build atop them instead.  :/

Since the last posting, I've also collected some crc32c test results on
a bunch of different x86/powerpc/sparc platforms.  The results can be
viewed here: http://goo.gl/sgt3i ; the "crc32-kern-le" and "crc32c"
columns describe the performance of the kernel's current crc32 and
crc32c software implementations.  The "crc32c-by8-le" column shows
crc32c performance with this patchset applied.  I expect crc32
performance to be roughly the same.

The two _boost columns at the right side of the spreadsheet shows how much
faster the new implementation is over the old one.  As you can see, crc32
rises substantially, and crc32c experiences a huge increase.

+A brief CRC tutorial.
+
+A CRC is a long-division remainder.  You add the CRC to the message,
+and the whole thing (message+CRC) is a multiple of the given
+CRC polynomial.  To check the CRC, you can either check that the
+CRC matches the recomputed value, *or* you can check that the
+remainder computed on the message+CRC is 0.  This latter approach
+is used by a lot of hardware implementations, and is why so many
+protocols put the end-of-frame flag after the CRC.
+
+It's actually the same long division you learned in school, except that
+- We're working in binary, so the digits are only 0 and 1, and
+- When dividing polynomials, there are no carries.  Rather than add and
+  subtract, we just xor.  Thus, we tend to get a bit sloppy about
+  the difference between adding and subtracting.
+
+Like all division, the remainder is always smaller than the divisor.
+To produce a 32-bit CRC, the divisor is actually a 33-bit CRC polynomial.
+Since it's 33 bits long, bit 32 is always going to be set, so usually the
+CRC is written in hex with the most significant bit omitted.  (If you're
+familiar with the IEEE 754 floating-point format, it's the same idea.)
+
+Note that a CRC is computed over a string of *bits*, so you have
+to decide on the endianness of the bits within each byte.  To get
+the best error-detecting properties, this should correspond to the
+order they're actually sent.  For example, standard RS-232 serial is
+little-endian; the most significant bit (sometimes used for parity)
+is sent last.  And when appending a CRC word to a message, you should
+do it in the right order, matching the endianness.
+
+Just like with ordinary division, you proceed one digit (bit) at a time.
+Each step of the division you take one more digit (bit) of the dividend
+and append it to the current remainder.  Then you figure out the
+appropriate multiple of the divisor to subtract to being the remainder
+back into range.  In binary, this is easy - it has to be either 0 or 1,
+and to make the XOR cancel, it's just a copy of bit 32 of the remainder.
+
+When computing a CRC, we don't care about the quotient, so we can
+throw the quotient bit away, but subtract the appropriate multiple of
+the polynomial from the remainder and we're back to where we started,
+ready to process the next bit.
+
+A big-endian CRC written this way would be coded like:
+for (i = 0; i < input_bits; i++) {
+	multiple = remainder & 0x80000000 ? CRCPOLY : 0;
+	remainder = (remainder << 1 | next_input_bit()) ^ multiple;
+}
+
+Notice how, to get at bit 32 of the shifted remainder, we look
+at bit 31 of the remainder *before* shifting it.
+
+But also notice how the next_input_bit() bits we're shifting into
+the remainder don't actually affect any decision-making until
+32 bits later.  Thus, the first 32 cycles of this are pretty boring.
+Also, to add the CRC to a message, we need a 32-bit-long hole for it at
+the end, so we have to add 32 extra cycles shifting in zeros at the
+end of every message,
+
+These details lead to a standard trick: rearrange merging in the
+next_input_bit() until the moment it's needed.  Then the first 32 cycles
+can be precomputed, and merging in the final 32 zero bits to make room
+for the CRC can be skipped entirely.  This changes the code to:
+
+for (i = 0; i < input_bits; i++) {
+	remainder ^= next_input_bit() << 31;
+	multiple = (remainder & 0x80000000) ? CRCPOLY : 0;
+	remainder = (remainder << 1) ^ multiple;
+}
+
+With this optimization, the little-endian code is particularly simple:
+for (i = 0; i < input_bits; i++) {
+	remainder ^= next_input_bit();
+	multiple = (remainder & 1) ? CRCPOLY : 0;
+	remainder = (remainder >> 1) ^ multiple;
+}
+
+The most significant coefficient of the remainder polynomial is stored
+in the least significant bit of the binary "remainder" variable.
+The other details of endianness have been hidden in CRCPOLY (which must
+be bit-reversed) and next_input_bit().
+
+As long as next_input_bit is returning the bits in a sensible order, we don't
+*have* to wait until the last possible moment to merge in additional bits.
+We can do it 8 bits at a time rather than 1 bit at a time:
+for (i = 0; i < input_bytes; i++) {
+	remainder ^= next_input_byte() << 24;
+	for (j = 0; j < 8; j++) {
+		multiple = (remainder & 0x80000000) ? CRCPOLY : 0;
+		remainder = (remainder << 1) ^ multiple;
+	}
+}
+
+Or in little-endian:
+for (i = 0; i < input_bytes; i++) {
+	remainder ^= next_input_byte();
+	for (j = 0; j < 8; j++) {
+		multiple = (remainder & 1) ? CRCPOLY : 0;
+		remainder = (remainder >> 1) ^ multiple;
+	}
+}
+
+If the input is a multiple of 32 bits, you can even XOR in a 32-bit
+word at a time and increase the inner loop count to 32.
+
+You can also mix and match the two loop styles, for example doing the
+bulk of a message byte-at-a-time and adding bit-at-a-time processing
+for any fractional bytes at the end.
+
+To reduce the number of conditional branches, software commonly uses
+the byte-at-a-time table method, popularized by Dilip V. Sarwate,
+"Computation of Cyclic Redundancy Checks via Table Look-Up", Comm. ACM
+v.31 no.8 (August 1998) p. 1008-1013.
+
+Here, rather than just shifting one bit of the remainder to decide
+in the correct multiple to subtract, we can shift a byte at a time.
+This produces a 40-bit (rather than a 33-bit) intermediate remainder,
+and the correct multiple of the polynomial to subtract is found using
+a 256-entry lookup table indexed by the high 8 bits.
+
+(The table entries are simply the CRC-32 of the given one-byte messages.)
+
+When space is more constrained, smaller tables can be used, e.g. two
+4-bit shifts followed by a lookup in a 16-entry table.
+
+It is not practical to process much more than 8 bits at a time using this
+technique, because tables larger than 256 entries use too much memory and,
+more importantly, too much of the L1 cache.
+
+To get higher software performance, a "slicing" technique can be used.
+See "High Octane CRC Generation with the Intel Slicing-by-8 Algorithm",
+ftp://download.intel.com/technology/comms/perfnet/download/slicing-by-8.pdf
+
+This does not change the number of table lookups, but does increase
+the parallelism.  With the classic Sarwate algorithm, each table lookup
+must be completed before the index of the next can be computed.
+
+A "slicing by 2" technique would shift the remainder 16 bits at a time,
+producing a 48-bit intermediate remainder.  Rather than doing a single
+lookup in a 65536-entry table, the two high bytes are looked up in
+two different 256-entry tables.  Each contains the remainder required
+to cancel out the corresponding byte.  The tables are different because the
+polynomials to cancel are different.  One has non-zero coefficients from
+x^32 to x^39, while the other goes from x^40 to x^47.
+
+Since modern processors can handle many parallel memory operations, this
+takes barely longer than a single table look-up and thus performs almost
+twice as fast as the basic Sarwate algorithm.
+
+This can be extended to "slicing by 4" using 4 256-entry tables.
+Each step, 32 bits of data is fetched, XORed with the CRC, and the result
+broken into bytes and looked up in the tables.  Because the 32-bit shift
+leaves the low-order bits of the intermediate remainder zero, the
+final CRC is simply the XOR of the 4 table look-ups.
+
+But this still enforces sequential execution: a second group of table
+look-ups cannot begin until the previous groups 4 table look-ups have all
+been completed.  Thus, the processor's load/store unit is sometimes idle.
+
+To make maximum use of the processor, "slicing by 8" performs 8 look-ups
+in parallel.  Each step, the 32-bit CRC is shifted 64 bits and XORed
+with 64 bits of input data.  What is important to note is that 4 of
+those 8 bytes are simply copies of the input data; they do not depend
+on the previous CRC at all.  Thus, those 4 table look-ups may commence
+immediately, without waiting for the previous loop iteration.
+
+By always having 4 loads in flight, a modern superscalar processor can
+be kept busy and make full use of its L1 cache.
+
+Two more details about CRC implementation in the real world:
+
+Normally, appending zero bits to a message which is already a multiple
+of a polynomial produces a larger multiple of that polynomial.  Thus,
+a basic CRC will not detect appended zero bits (or bytes).  To enable
+a CRC to detect this condition, it's common to invert the CRC before
+appending it.  This makes the remainder of the message+crc come out not
+as zero, but some fixed non-zero value.  (The CRC of the inversion
+pattern, 0xffffffff.)
+
+The same problem applies to zero bits prepended to the message, and a
+similar solution is used.  Instead of starting the CRC computation with
+a remainder of 0, an initial remainder of all ones is used.  As long as
+you start the same way on decoding, it doesn't make a difference.

Subject: [PATCH 6358/6423] crc32: simplify unit test code

Replace the unit test provided in crc32.c, which doesn't have a makefile
and doesn't compile with current headers, with a simpler self test
routine that also gives a measure of performance and runs at module init
time.  The self test option can be enabled through a configuration
option CONFIG_CRC32_SELFTEST.

The test stresses the pre and post loops and is thus not very realistic
since actual uses will likely have addresses and lengths that are at
least 4 byte aligned.  However, the main loop is long enough so that the
performance is dominated by that loop.

The expected values for crc32_le and crc32_be were generated with the
original version of crc32.c using CRC_BITS_LE = 8 and CRC_BITS_BE = 8.
These values were then used to check all the values of the BITS
parameters in both the original and new versions.

The performance results show some variability from run to run in spite
of attempts to both warm the cache and reduce the amount of OS noise by
limiting interrutps during the test.  To get comparable results and to
analyse options wrt performance the best time reported over a small
sample of runs has been taken.

Subject: [PATCH 6359/6423] crc32: miscellaneous cleanups

Misc cleanup of lib/crc32.c and related files.

- remove unnecessary header files.

- straighten out some convoluted ifdef's

- rewrite some references to 2 dimensional arrays as 1 dimensional
  arrays to make them correct.  I.e.  replace tab[i] with tab[0][i].

- a few trivial whitespace changes

- fix a warning in gen_crc32tables.c caused by a mismatch in the type of
  the pointer passed to output table.  Since the table is only used at
  kernel compile time, it is simpler to make the table big enough to hold

Subject: [PATCH 6360/6423] crc32: fix mixing of endian-specific types

crc32.c in its original version freely mixed u32, __le32 and __be32 types
which caused warnings from sparse with __CHECK_ENDIAN__.  This patch fixes
these by forcing the types to u32.

Subject: [PATCH 6361/6423] crc32: make CRC_*_BITS definition correspond to
 actual bit counts

crc32.c provides a choice of one of several algorithms for computing the
LSB and LSB versions of the CRC32 checksum based on the parameters
CRC_LE_BITS and CRC_BE_BITS.

In the original version the values 1, 2, 4 and 8 respectively selected
versions of the alrogithm that computed the crc 1, 2, 4 and 32 bits as a
time.

This patch series adds a new version that computes the CRC 64 bits at a
time.  To make things easier to understand the parameter has been
reinterpreted to actually stand for the number of bits processed in each
step of the algorithm so that the old value 8 has been replaced with the
value 32.

This also allows us to add in a widely used crc algorithm that computes
the crc 8 bits at a time called the Sarwate algorithm.

Subject: [PATCH 6363/6423] crc32: optimize loop counter for x86

Add two changes that improve the performance of x86 systems

1. replace main loop with incrementing counter this change improves
   the performance of the selftest by about 5-6% on Nehalem CPUs.  The
   apparent reason is that the compiler can use the loop index to perform
   an indexed memory access.  This is reported to make the performance of
   PowerPC CPUs to get worse.

2. replace the rem_len loop with incrementing counter this change
   improves the performance of the selftest, which has more than the usual
   number of occurances, by about 1-2% on x86 CPUs.  In actual work loads
   the length is most often a multiple of 4 bytes and this code does not
   get executed as often if at all.  Again this change is reported to make
   the performance of PowerPC get worse.

Since lib/crc32.c now provides crc32c, remove the software implementation
here and call the library function instead.

Subject: [PATCH 6369/6423] poll: add poll_requested_events() and
 poll_does_not_wait() functions

In some cases the poll() implementation in a driver has to do different
things depending on the events the caller wants to poll for.  An example
is when a driver needs to start a DMA engine if the caller polls for
POLLIN, but doesn't want to do that if POLLIN is not requested but instead
only POLLOUT or POLLPRI is requested.  This is something that can happen
in the video4linux subsystem among others.

Unfortunately, the current epoll/poll/select implementation doesn't
provide that information reliably.  The poll_table_struct does have it: it
has a key field with the event mask.  But once a poll() call matches one
or more bits of that mask any following poll() calls are passed a NULL
poll_table pointer.

Also, the eventpoll implementation always left the key field at ~0 instead
of using the requested events mask.

This was changed in eventpoll.c so the key field now contains the actual
events that should be polled for as set by the caller.

The solution to the NULL poll_table pointer is to set the qproc field to
NULL in poll_table once poll() matches the events, not the poll_table
pointer itself.  That way drivers can obtain the mask through a new
poll_requested_events inline.

The poll_table_struct can still be NULL since some kernel code calls it
internally (netfs_state_poll() in ./drivers/staging/pohmelfs/netfs.h).  In
that case poll_requested_events() returns ~0 (i.e.  all events).

Very rarely drivers might want to know whether poll_wait will actually
wait.  If another earlier file descriptor in the set already matched the
events the caller wanted to wait for, then the kernel will return from the
select() call without waiting.  This might be useful information in order
to avoid doing expensive work.

A new helper function poll_does_not_wait() is added that drivers can use
to detect this situation.  This is now used in sock_poll_wait() in
include/net/sock.h.  This was the only place in the kernel that needed
this information.

Drivers should no longer access any of the poll_table internals, but use
the poll_requested_events() and poll_does_not_wait() access functions
instead.  In order to enforce that the poll_table fields are now prepended
with an underscore and a comment was added warning against using them
directly.

This required a change in unix_dgram_poll() in unix/af_unix.c which used
the key field to get the requested events.  It's been replaced by a call
to poll_requested_events().

For qproc it was especially important to change its name since the
behavior of that field changes with this patch since this function pointer
can now be NULL when that wasn't possible in the past.

Any driver accessing the qproc or key fields directly will now fail to compile.

Some notes regarding the correctness of this patch: the driver's poll()
function is called with a 'struct poll_table_struct *wait' argument.  This
pointer may or may not be NULL, drivers can never rely on it being one or
the other as that depends on whether or not an earlier file descriptor in
the select()'s fdset matched the requested events.

There are only three things a driver can do with the wait argument:

1) obtain the key field:

	events = wait ? wait->key : ~0;

   This will still work although it should be replaced with the new
   poll_requested_events() function (which does exactly the same).
   This will now even work better, since wait is no longer set to NULL
   unnecessarily.

2) use the qproc callback. This could be deadly since qproc can now be
   NULL. Renaming qproc should prevent this from happening. There are no
   kernel drivers that actually access this callback directly, BTW.

3) test whether wait == NULL to determine whether poll would return without
   waiting. This is no longer sufficient as the correct test is now
   wait == NULL || wait->_qproc == NULL.

   However, the worst that can happen here is a slight performance hit in
   the case where wait != NULL and wait->_qproc == NULL. In that case the
   driver will assume that poll_wait() will actually add the fd to the set
   of waiting file descriptors. Of course, poll_wait() will not do that
   since it tests for wait->_qproc. This will not break anything, though.

   There is only one place in the whole kernel where this happens
   (sock_poll_wait() in include/net/sock.h) and that code will be replaced
   by a call to poll_does_not_wait() in the next patch.

   Note that even if wait->_qproc != NULL drivers cannot rely on poll_wait()
   actually waiting. The next file descriptor from the set might match the
   event mask and thus any possible waits will never happen.

Subject: [PATCH 6370/6423] epoll: comment the funky #ifdef

Looking for a bug in -rt, I stumbled across this code here from: commit
2dfa4eeab0fc ("epoll keyed wakeups: teach epoll about hints coming with
the wakeup key"), specifically:

  #ifdef CONFIG_DEBUG_LOCK_ALLOC
  static inline void ep_wake_up_nested(wait_queue_head_t *wqueue,
                                      unsigned long events, int subclass)
  {
         unsigned long flags;

         spin_lock_irqsave_nested(&wqueue->lock, flags, subclass);
         wake_up_locked_poll(wqueue, events);
         spin_unlock_irqrestore(&wqueue->lock, flags);
  }
  #else
  static inline void ep_wake_up_nested(wait_queue_head_t *wqueue,
                                      unsigned long events, int subclass)
  {
         wake_up_poll(wqueue, events);
  }
  #endif

You change the function of ep_wake_up_nested() depending on whether
CONFIG_DEBUG_LOCK_ALLOC is set or not.  This looks awfully suspicious,
and there's no comment to explain why.  I initially thought that this
was trying to fool lockdep, and hiding a real bug.

Investigating it, I found the creation of wake_up_nested() (which no
longer exists) but was created for the sole purpose of epoll and its
strange wake ups, as explained in commit 0ccf831cbee9 ("lockdep:
annotate epoll")

Although the commit message says "annotate epoll" the change log is much
better at explaining what is happening than what is in the actual code.
Thus a comment is really necessary here.  And to save the time of other
developers from having to go trudging through the git logs trying to
figure out why this code exists.

I took parts of the change log and placed it into a comment above the
affected code.  This will make the description of what is happening more
visible to new developers that have to look at this code for the first
time.

Printing the error code makes it easier to debug the cause of a mount

not be mounted read-writeable because my SD card was write-protected.
Without an error code it looks like the SD card was not detected at all.

Subject: [PATCH 6376/6423] rtc/rtc-spear: call platform_set_drvdata() before
 registering rtc device

rtc_device_register() calls rtc-spear routines internally.  These
routines call dev_get_drvdata() to get struct spear_rtc_config.
Currently, platform_set_drvdata is called after rtc device is
registered.  This causes system to crash, as dev_get_drvdata returns
NULL.

For this we need to call platform_set_drvdata() before registering rtc
device.  This requires further cleanup, that leads to removal of
dev_set_drvdata on rtc->dev, which was just not required at all.

Also, we change the parameter to request_irq and pass pointer to config
instead of pointer to rtc struct.

This patch brings all above changes.

Subject: [PATCH 6380/6423] drivers/rtc/rtc-twl.c: optimize IRQ bit access

As the TWL RTC driver has a cached copy of enabled RTC interrupt bits in
variable rtc_irq_bits, that can be checked before really setting or
masking any of the interrupt bits.

Subject: [PATCH 6381/6423] drivers/rtc/rtc-twl.c: enable RTC irrespective of
 its prior state

As part of probe, before enabling RTC, RTC_CTRL register is read to check
if it is already running.  If RTC is used by kernel alone, then this read
is not required.  Even if RTC was enabled already by boot loader, setting
STOP_RTC bit again should not harm.  Hence removed unwanted read
operation.

Subject: [PATCH 6382/6423] drivers/rtc/rtc-twl.c: simplify RTC interrupt
 clearing

For clearing RTC interrupt, programming ALARM bit only is sufficient, as
all other bits are any way not affected by writing 0 to them.

Hence removed unwanted OR operation.

Subject: [PATCH 6383/6423] drivers/rtc/rtc-twl.c: return correct RTC event
 from ISR

Following changes are made as part of this change:

1. As TWL RTC supports periodic interrupt, the correct event should be
   RTC_PF instead of RTC_UF.

2. No need to initialize variable "events" to 0 & then OR it with the
   event values.  Hence fixing it.

Subject: [PATCH 6384/6423] drivers/rtc: remove IRQF_DISABLED

Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts
disabled") we run all interrupt handlers with interrupts disabled and we
even check and yell when an interrupt handler returns with interrupts
enabled - see commit b738a50a2026 ("genirq: warn when handler enables
interrupts").

So now this flag is a NOOP and can be removed.

ALARM_IRQ_MASK and ALARM_CTRL setting.  max8925_rtc_set_alarm() should
enable/disable alarm according to ALARM_CTRL reg setting.

Subject: [PATCH 6389/6423] rtc: ds1307: refactor chip_desc table

The chip_desc table is suboptimal.  Currently it requires an entry for
every new chip type, even if it is empty.  This has already been
forgotten for the ds1388.  Refactor the code, so new entries are only
needed, when they chip type really needs a (non-empty) description.
Also make the table visually more appealing.

Since '*outlen' is initialized to zero, it is currently possible to
create a filename of length (FAT_LFN_LEN + 1) when utf8 is not enabled.
To enforce the FAT_LFN_LEN limit, we must perform one less iteration.

Subject: [PATCH 6395/6423] ptrace: the killed tracee should not enter the
 syscall

Another old/known problem.  If the tracee is killed after it reports
syscall_entry, it starts the syscall and debugger can't control this.
This confuses the users and this creates the security problems for
ptrace jailers.

Change tracehook_report_syscall_entry() to return non-zero if killed,
this instructs syscall_trace_enter() to abort the syscall.

Subject: [PATCH 6397/6423] ptrace: don't modify flags on PTRACE_SETOPTIONS
 failure

On ptrace(PTRACE_SETOPTIONS, pid, 0, <opts>), we used to set those
option bits which are known, and then fail with -EINVAL if there are
some unknown bits in <opts>.

This is inconsistent with typical error handling, which does not change
any state if input is invalid.

This patch changes PTRACE_SETOPTIONS behavior so that in this case, we
return -EINVAL and don't change any bits in task->ptrace.

It's very unlikely that there is userspace code in the wild which will
be affected by this change: it should have the form

    ptrace(PTRACE_SETOPTIONS, pid, 0, PTRACE_O_BOGUSOPT)

where PTRACE_O_BOGUSOPT is a constant unknown to the kernel.  But kernel
headers, naturally, don't contain any PTRACE_O_BOGUSOPTs, thus the only
way userspace can use one if it defines one itself.  I can't see why
anyone would do such a thing deliberately.

instead of using explicit numeric constants, to ensure we don't mess up
relationship between bit positions and event ids.

PT_EVENT_FLAG_SHIFT was not particularly useful, PT_OPT_FLAG_SHIFT with
value of PT_EVENT_FLAG_SHIFT-1 is easier to use.

PT_TRACE_MASK constant is nuked, the only its use is replaced by
(PTRACE_O_MASK << PT_OPT_FLAG_SHIFT).

Subject: [PATCH 6399/6423] ptrace: make PTRACE_SEIZE set ptrace options
 specified in 'data' parameter

This can be used to close a few corner cases in strace where we get
unwanted racy behavior after attach, but before we have a chance to set
options (the notorious post-execve SIGTRAP comes to mind), and removes
the need to track "did we set opts for this task" state in strace
internals.

While we are at it:

Make it possible to extend SEIZE in the future with more functionality
by passing non-zero 'addr' parameter.  To that end, error out if 'addr'
is non-zero.  PTRACE_ATTACH did not (and still does not) have such
check, and users (strace) do pass garbage there...  let's avoid
repeating this mistake with SEIZE.

Set all task->ptrace bits in one operation - before this change, we were
adding PT_SEIZED and PT_PTRACE_CAP with task->ptrace |= BIT ops.  This
was probably ok (not a bug), but let's be on a safer side.

Changes since v2: use (unsigned long) casts instead of (long) ones, move
PTRACE_SEIZE_DEVEL-related code to separate lines of code.

Subject: [PATCH 6400/6423] ptrace: renumber PTRACE_EVENT_STOP so that future
 new options and events can match

PTRACE_EVENT_foo and PTRACE_O_TRACEfoo used to match.

New PTRACE_EVENT_STOP is the first event which has no corresponding
PTRACE_O_TRACE option.  If we will ever want to add another such option,
its PTRACE_EVENT's value will collide with PTRACE_EVENT_STOP's value.

This patch changes PTRACE_EVENT_STOP value to prevent this.

While at it, added a comment - the one atop PTRACE_EVENT block, saying
"Wait extended result codes for the above trace options", is not true
for PTRACE_EVENT_STOP.

PTRACE_SEIZE code is tested and ready for production use, remove the
code which requires special bit in data argument to make PTRACE_SEIZE
work.

Strace team prepares for a new release of strace, and we would like to
ship the code which uses PTRACE_SEIZE, preferably after this change goes
into released kernel.

Subject: [PATCH 6402/6423] Hexagon: use set_current_blocked() and
 block_sigmask()

As described in e6fa16ab9c1e ("signal: sigprocmask() should do
retarget_shared_pending()") the modification of current->blocked is
incorrect as we need to check whether the signal we're about to block is
pending in the shared queue.

Also, use the new helper function introduced in commit 5e6292c0f28f
("signal: add block_sigmask() for adding sigmask to current->blocked")
which centralises the code for updating current->blocked after
successfully delivering a signal and reduces the amount of duplicate
code across architectures.  In the past some architectures got this code
wrong, so using this helper function should stop that from happening
again.

Subject: [PATCH 6403/6423] signal: give SEND_SIG_FORCED more power to beat
 SIGNAL_UNKILLABLE

force_sig_info() and friends have the special semantics for synchronous
signals, this interface should not be used if the target is not current.
And it needs the fixes, in particular the clearing of SIGNAL_UNKILLABLE
is not exactly right.

However there are callers which have to use force_ exactly because it
clears SIGNAL_UNKILLABLE and thus it can kill the CLONE_NEWPID tasks,
although this is almost always is wrong by various reasons.

With this patch SEND_SIG_FORCED ignores SIGNAL_UNKILLABLE, like we do if
the signal comes from the ancestor namespace.

This makes the naming in prepare_signal() paths insane, fixed by the
next cleanup.

Note: this only affects SIGKILL/SIGSTOP, but this is enough for
force_sig() abusers.

Subject: [PATCH 6405/6423] signal: oom_kill_task: use SEND_SIG_FORCED instead
 of force_sig()

Change oom_kill_task() to use do_send_sig_info(SEND_SIG_FORCED) instead
of force_sig(SIGKILL).  With the recent changes we do not need force_ to
kill the CLONE_NEWPID tasks.

And this is more correct.  force_sig() can race with the exiting thread
even if oom_kill_task() checks p->mm != NULL, while
do_send_sig_info(group => true) kille the whole process.

Subject: [PATCH 6406/6423] signal: zap_pid_ns_processes:
 s/SEND_SIG_NOINFO/SEND_SIG_FORCED/

Change zap_pid_ns_processes() to use SEND_SIG_FORCED, it looks more
clear compared to SEND_SIG_NOINFO which relies on from_ancestor_ns logic
send_signal().

It is also more efficient if we need to kill a lot of tasks because it
doesn't alloc sigqueue.

While at it, add the __fatal_signal_pending(task) check as a minor
optimization.

Subject: [PATCH 6409/6423] usermodehelper: implement UMH_KILLABLE

Implement UMH_KILLABLE, should be used along with UMH_WAIT_EXEC/PROC.
The caller must ensure that subprocess_info->path/etc can not go away
until call_usermodehelper_freeinfo().

call_usermodehelper_exec(UMH_KILLABLE) does
wait_for_completion_killable.  If it fails, it uses
xchg(&sub_info->complete, NULL) to serialize with umh_complete() which
does the same xhcg() to access sub_info->complete.

If call_usermodehelper_exec wins, it can safely return.  umh_complete()
should get NULL and call call_usermodehelper_freeinfo().

Otherwise we know that umh_complete() was already called, in this case
call_usermodehelper_exec() falls back to wait_for_completion() which
should succeed "very soon".

Note: UMH_NO_WAIT == -1 but it obviously should not be used with
UMH_KILLABLE.  We delay the neccessary cleanup to simplify the back
porting.

No functional changes.  It is not sane to use UMH_KILLABLE with enum
umh_wait, but obviously we do not want another argument in
call_usermodehelper_* helpers.  Kill this enum, use the plain int.

Subject: [PATCH 6411/6423] usermodehelper: ____call_usermodehelper() doesn't
 need do_exit()

Minor cleanup.  ____call_usermodehelper() can simply return, no need to
call do_exit() explicitely.

Subject: [PATCH 6413/6423] kmod: make __request_module() killable

As Tetsuo Handa pointed out, request_module() can stress the system
while the oom-killed caller sleeps in TASK_UNINTERRUPTIBLE.

The task T uses "almost all" memory, then it does something which
triggers request_module().  Say, it can simply call sys_socket().  This
in turn needs more memory and leads to OOM.  oom-killer correctly
chooses T and kills it, but this can't help because it sleeps in
TASK_UNINTERRUPTIBLE and after that oom-killer becomes "disabled" by the
TIF_MEMDIE task T.

Make __request_module() killable.  The only necessary change is that
call_modprobe() should kmalloc argv and module_name, they can't live in
the stack if we use UMH_KILLABLE.  This memory is freed via
call_usermodehelper_freeinfo()->cleanup.

Subject: [PATCH 6414/6423] coredump: remove VM_ALWAYSDUMP flag

The motivation for this patchset was that I was looking at a way for a
qemu-kvm process, to exclude the guest memory from its core dump, which
can be quite large.  There are already a number of filter flags in
/proc/<pid>/coredump_filter, however, these allow one to specify 'types'
of kernel memory, not specific address ranges (which is needed in this
case).

Since there are no more vma flags available, the first patch eliminates
the need for the 'VM_ALWAYSDUMP' flag.  The flag is used internally by
the kernel to mark vdso and vsyscall pages.  However, it is simple
enough to check if a vma covers a vdso or vsyscall page without the need
for this flag.

The second patch then replaces the 'VM_ALWAYSDUMP' flag with a new
'VM_NODUMP' flag, which can be set by userspace using new madvise flags:
'MADV_DONTDUMP', and unset via 'MADV_DODUMP'.  The core dump filters
continue to work the same as before unless 'MADV_DONTDUMP' is set on the
region.

The qemu code which implements this features is at:

  http://people.redhat.com/~jbaron/qemu-dump/qemu-dump.patch

In my testing the qemu core dump shrunk from 383MB -> 13MB with this
patch.

I also believe that the 'MADV_DONTDUMP' flag might be useful for
security sensitive apps, which might want to select which areas are
dumped.

This patch:

The VM_ALWAYSDUMP flag is currently used by the coredump code to
indicate that a vma is part of a vsyscall or vdso section.  However, we
can determine if a vma is in one these sections by checking it against
the gate_vma and checking for a non-NULL return value from
arch_vma_name().  Thus, freeing a valuable vma bit.

Subject: [PATCH 6415/6423] coredump: add VM_NODUMP, MADV_NODUMP,
 MADV_CLEAR_NODUMP

Since we no longer need the VM_ALWAYSDUMP flag, let's use the freed bit
for 'VM_NODUMP' flag.  The idea is is to add a new madvise() flag:
MADV_DONTDUMP, which can be set by applications to specifically request
memory regions which should not dump core.

The specific application I have in mind is qemu: we can add a flag there
that wouldn't dump all of guest memory when qemu dumps core.  This flag
might also be useful for security sensitive apps that want to absolutely
make sure that parts of memory are not dumped.  To clear the flag use:
MADV_DODUMP.

Subject: [PATCH 6417/6423] proc: speed up /proc/stat handling

On a typical 16 cpus machine, "cat /proc/stat" gives more than 4096 bytes,
and is slow :

  # strace -T -o /tmp/STRACE cat /proc/stat | wc -c
  5826
  # grep "cpu " /tmp/STRACE
  read(0, "cpu  1949310 19 2144714 12117253"..., 32768) = 5826 <0.001504>

Thats partly because show_stat() must be called twice since initial
buffer size is too small (4096 bytes for less than 32 possible cpus)

Fix this by :

 1) Taking into account nr_irqs in the initial buffer sizing.

 2) Using ksize() to allow better filling of initial buffer.

This patch removes most of calls to vsnprintf() by adding num_to_str()
and seq_print_decimal_ull(), which prints decimal numbers without rich
functions provided by printf().

From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com>

Subject: [PATCH 6419/6423] procfs: speed up /proc/pid/stat, statm

Process accounting applications as top, ps visit some files under
/proc/<pid>.  With seq_put_decimal_ull(), we can optimize /proc/<pid>/stat
and /proc/<pid>/statm files.

This patch adds
  - seq_put_decimal_ll() for signed values.
  - allow delimiter == 0.
  - convert seq_printf() to seq_put_decimal_ull/ll in /proc/stat, statm.

Test result on a system with 2000+ procs.

Before patch:
  [kamezawa@bluextal test]$ top -b -n 1 | wc -l
  2223
  [kamezawa@bluextal test]$ time top -b -n 1 > /dev/null

  real    0m0.675s
  user    0m0.044s
  sys     0m0.121s

  [kamezawa@bluextal test]$ time ps -elf > /dev/null

  real    0m0.236s
  user    0m0.056s
  sys     0m0.176s

After patch:
  kamezawa@bluextal ~]$ time top -b -n 1 > /dev/null

  real    0m0.657s
  user    0m0.052s
  sys     0m0.100s

  [kamezawa@bluextal ~]$ time ps -elf > /dev/null

  real    0m0.198s
  user    0m0.050s
  sys     0m0.145s

Considering top, ps tend to scan /proc periodically, this will reduce cpu
consumption by top/ps to some extent.

Subject: [PATCH 6420/6423] proc-ns: use d_set_d_op() API to set dentry ops in
 proc_ns_instantiate().

The namespace cleanup path leaks a dentry which holds a reference count
on a network namespace.  Keeping that network namespace from being freed
when the last user goes away.  Leaving things like vlan devices in the
leaked network namespace.

If you use ip netns add for much real work this problem becomes apparent
pretty quickly.  It light testing the problem hides because frequently
you simply don't notice the leak.

Use d_set_d_op() so that DCACHE_OP_* flags are set correctly.

This issue exists back to 3.0.

Subject: [PATCH 6421/6423] seq_file: add seq_set_overflow(), seq_overflow()

It is undocumented but a seq_file's overflow state is indicated by
m->count == m->size.  Add seq_set_overflow() and seq_overflow() to
set/check overflow status explicitly.

Based on an idea from Eric Dumazet.

Subject: [PATCH 6423/6423] Fix potential endless loop in kswapd when
 compaction is not enabled

We should only test compaction_suitable if the kernel is built with
CONFIG_COMPACTION, otherwise the stub compaction_suitable function will
always return COMPACT_SKIPPED and send kswapd into an infinite loop.
