John W. Linville says:

====================
One last batch of stragglers intended for 3.9...

For the iwlwifi pull, Johannes says:

"I hadn't expected to ask you to pull iwlwifi-next again, but I have a
number of fixes most of which I'd also send in after rc1, so here it is.

The first commit is a merge error between mac80211-next and
iwlwifi-next; in addition I have fixes for P2P scanning and MVM driver
MAC (virtual interface) management from Ilan, a CT-kill (critical
temperature) fix from Eytan, and myself fixed three different little but
annoying bugs in the MVM driver.

The only ones I might not send for -rc1 are Emmanuel's debug patch, but
OTOH it should help greatly if there are any issues, and my own time
event debugging patch that I used to find the race condition but we
decided to keep it for the future."

For the mac80211 pull, Johannes says:

"Like iwlwifi-next, this would almost be suitable for rc1.

I have a fix for station management on non-TDLS drivers, a CAB queue
crash fix for mesh, a fix for an annoying (but harmless) warning, a
tracing fix and a documentation fix. Other than that, only a few mesh
cleanups."

Along with that is a fix for memory corruption in rtlwifi, an
orinoco_usb fix to avoid allocating a DMA buffer on the stack, an a
hostap fix to return -ENOMEM instead of -1 after a memory allocation
failure.  The remaining bits implement 802.11ac support for the mwifiex
driver -- I think that is still worth getting into 3.9.

Please let me know if there are problems!
