Merge tag 'v3.7-rc2' into drm-intel-next-queued 



Linux 3.7-rc2

Backmerge to solve two ugly conflicts:
- uapi. We've already added new ioctl definitions for -next. Do I need to say more?
- wc support gtt ptes. We've had to revert this for snb+ for 3.7 and
  also fix a few other things in the code. Now we know how to make it
  work on snb+, but to avoid losing the other fixes do the backmerge
  first before re-enabling wc gtt ptes on snb+.

And a few other minor things, among them git getting confused in
intel_dp.c and seemingly causing a conflict out of nothing ...

What:	/proc/<pid>/oom_adj

When:	August 2012

Why:	/proc/<pid>/oom_adj allows userspace to influence the oom killer's

	badness heuristic used to determine which task to kill when the kernel

	is out of memory.



	The badness heuristic has since been rewritten since the introduction of

	this tunable such that its meaning is deprecated.  The value was

	implemented as a bitshift on a score generated by the badness()

	function that did not have any precise units of measure.  With the

	rewrite, the score is given as a proportion of available memory to the

	task allocating pages, so using a bitshift which grows the score

	exponentially is, thus, impossible to tune with fine granularity.



	A much more powerful interface, /proc/<pid>/oom_score_adj, was

	introduced with the oom killer rewrite that allows users to increase or

	decrease the badness score linearly.  This interface will replace

	/proc/<pid>/oom_adj.



	A warning will be emitted to the kernel log if an application uses this

	deprecated interface.  After it is printed once, future warnings will be

	suppressed until the kernel is rebooted.

What:		/sys/block/<disk>/queue/write_same_max_bytes

Date:		January 2012

Contact:	Martin K. Petersen <martin.petersen@oracle.com>

Description:

		Some devices support a write same operation in which a

		single data block can be written to a range of several

		contiguous blocks on storage. This can be used to wipe

		areas on disk or to initialize drives in a RAID

		configuration. write_same_max_bytes indicates how many

		bytes can be written in a single write same command. If

		write_same_max_bytes is 0, write same is not supported

		by the device.
