John W. Linville says:

====================
This batch of fixes is intended for the 3.7 stream...

This includes a pull of the Bluetooth tree.  Gustavo says:

"A few important fixes to go into 3.7. There is a new hw support by Marcos
Chaparro. Johan added a memory leak fix and hci device index list fix.
Also Marcel fixed a race condition in the device set up that was prevent the
bt monitor to work properly. Last, Paulo Sérgio added a fix to the error
status when pairing for LE fails. This was prevent userspace to work to handle
the failure properly."

Regarding the mac80211 pull, Johannes says:

"I have a locking fix for some SKB queues, a variable initialization to
avoid crashes in a certain failure case, another free_txskb fix from
Felix and another fix from him to avoid calling a stopped driver, a fix
for a (very unlikely) memory leak and a fix to not send null data
packets when resuming while not associated."

Regarding the iwlwifi pull, Johannes says:

"Two more fixes for iwlwifi ... one to use ieee80211_free_txskb(), and
one to check DMA mapping errors, please pull."

On top of that, Johannes also included a wireless regulatory fix
to allow 40 MHz on channels 12 and 13 in world roaming mode.  Also,
Hauke Mehrtens fixes a #ifdef typo in brcmfmac.
