John W. Linville says:

====================
Here is a handful of fixes intended for 3.6.

Daniel Drake offers a cfg80211 fix to consume pending events before
taking a wireless device down.  This prevents a resource leak.

Stanislaw Gruszka gives us a fix for a NULL pointer dereference in
rt61pci.

Johannes Berg provides an iwlwifi patch to disable "greenfield" mode.
Use of that mode was causing a rate scaling problem in for iwlwifi.
