Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next 



John W. Linville says:

====================
This pull request is intended for 3.8...

This includes a Bluetooth pull.  Gustavo says:

"A few more patches to 3.8, I hope they can still make it to mainline!
The most important ones are the socket option for the SCO protocol to allow
accept/refuse new connections from userspace. Other than that I added some
fixes and Andrei did more AMP work."

Also, a mac80211 pull.  Johannes says:

"If you think there's any chance this might make it still, please pull my
mac80211-next tree (per below). This contains a relatively large number
of fixes to the previous code, as well as a few small features:
 * VHT association in mac80211
 * some new debugfs files
 * P2P GO powersave configuration
 * masked MAC address verification

The biggest patch is probably the BSS struct changes to use RCU for
their IE buffers to fix potential races. I've not tagged this for stable
because it's pretty invasive and nobody has ever seen any bugs in this
area as far as I know."

Several other drivers get some attention, including ath9k, brcmfmac,
brcmsmac, and a number of others.  Also, Hauke gives us a series that
improves watchdog support for the bcma and ssb busses.  Finally, Bill
Pemberton delivers a group of "remove __dev* attributes" for wireless
drivers -- these generate some "section mismatch" warnings, but Greg
K-H assures me that they will disappear by the time -rc1 is released.

This also includes a pull of the wireless tree to avoid merge
conflicts.
