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

John W. Linville says:

====================
This is one more set of fixes intended for the 3.11 stream...

For the mac80211 bits, Johannes says:

"I have three more patches for the 3.11 stream: Felix's fix for the
fairly visible brcmsmac crash, a fix from Simon for an IBSS join bug I
found and a fix for a channel context bug in IBSS I'd introduced."

Along with those...

Sujith Manoharan makes a minor change to not use a PLL hang workaroun
for AR9550.  This one-liner fixes a couple of bugs reported in the Red Hat
bugzilla.

Helmut Schaa addresses an ath9k_htc bug that mangles frame headers
during Tx.  This fix is small, tested by the bug reported and isolated
to ath9k_htc.

Stanislaw Gruszka reverts a recent iwl4965 change that broke rfkill
notification to user space.

Please let me know if there are problems!
