John W. Linville says:

====================
Please pull this batch of fixes intended for the 3.14 stream!

For the mac80211 bits, Johannes says:

"This is just a collection of small fixes, the commit logs explain the
details. The only thing that isn't strictly a fix is the 5/10 MHz
enabling, I had forgotten this and there's little point in waiting
longer. The patch simply removes the force-disable code that I put in
when there was a problem with the userspace API (that has long been
fixed.)"

For the iwlwifi bits, Emmanuel says:

"I have an important fix that disables A band in case the driver thought
it was enabled, and the firmware disagreed. We ended up making the
firmware unhappy. I also fix the station table in AP mode and fix the
scan while we have BT working.
Johannes removes a static variable that could potentially lead to to
issues on multi-device setups and disables scheduled scan to avoid
issues with old versions of wpa_supplicant.
A small fix from David on scan and a few new device IDs for 7265."

On top of that...

Oleksij Rempel adds a USB ID to the ar5523 driver and changes the
default powersave setting for ath9k_htc to "off", due to observed
stability issues (based on an equivalent ath9k patch).

Stanislaw Gruszka similarly disables powersave for a couple of rt2x00
drivers.  He also fixes a couple of scheduling while atomic issues
in ath9k_htc.

Sujith Manoharan rounds-out the powersave disables with one for ath9k.
He also fixes a build prolem with ath9k on ARM and fixes an ath9k Tx
power calculation.

Finally, Andrea Merello fixes a couple of lingering DMA mapping
problems in the rtl8180 driver.
