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

John W. Linville says:

====================
This will probably be the last batch of wireless fixes intended
for 3.10.  Many of these are one- or two-liners, and a couple of
others are mostly relocating existing code to avoid races or to
limit the code to effecting specific hardware, etc.

The mac80211 fixes have a couple of exceptions to the above.
Regarding those, Johannes says:

"Following davem's complaint about my patch, here's a new pull request
w/o the patch he was complaining about, but instead with the const
fix rolled into the fix.

I have a fix for radar detection, one for rate control and a workaround
for broken HT APs which is a regression fix because we didn't rely
on them to be correct before."

Johannes also sends some iwlwifi fixes:

"I picked up Nikolay's patch for the chain noise calibration bug
that seems to have been there forever, a fix from Emmanuel for
setting TX flags on BAR frames and a fix of my own to avoid printing
request_module() errors if the kernel isn't even modular. We also
have our own version of Stanislaw's fix for rate control."

Along with those...

Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU
value is set to too small of a value.

Arend van Spriel sends a revised brcmsmac bug that fixes a regression
caused by a bad return value in an earlier patch.  He also sends a
brcmfmac fix to avoid an oops when loading the driver at boot.

Daniel Drake fixes a race condition in btmrvl that causes hangs on
suspend for OLPC hardware.

Johan Hedberg adds a check to avoid sending a
HCI_Delete_Stored_Link_Key command to devices that don't support them,
avoiding some scary looking log spam.

Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates
higher than 1Mb/s on older wireless networks.  He also sends an rt2x00
fix to reinstate older tx power handling behavior for some devices
that didn't work well with the current code.
