commit 604c4ef1c453a1b2ea2cdf04d2b49afec421ebfa Dave, Here is a set of fixes for 3.3. This includes the ones that I originally posted on Monday, the bcma ones from Linus, plus a few more... From the Monday pull request: "Included is a fix for a signedness bug in ipw2x00 from Dan Carpenter, a fix for an oops when ejecting a b43 card from Guennadi Liakhovetski (with a minor modification by me as noted in the changelog), a mac80211 regresion fix from Johannes Berg for a bug related to station management, and a final fix for the rt2800pci spurious interrupt issue from Stanislaw Gruszka." On top of those are the ones from Linus' "brcm80211 breakage.." thread: http://www.spinics.net/lists/netdev/msg185393.html http://www.spinics.net/lists/netdev/msg185722.html In addition, we have a work-around/fix for a brcmfmac build issue with gcc 4.7 from Alexandre Oliva, a fix for an "always true" check in mwl8k from Dan Carpenter, a fix for an iwlwifi build warning from Fabio Estevam, a fix from Felix Fietkau for an ath9k regression regarding interpretation of the rx KeyMiss flag, a fix for a bottom-half race in mac80211 from Helmut Schaa, a fix for a mac80211 memory leak from Jesper Juhl, a fix for an mwl8k sparse endian check from Yogesh Ashok Powar, and a fix for a mac80211 NULL pointer dereference from Yoni Divinsky. Also includes are some MAINTAINERS updates from Rafał Miłecki, as well as his fix to prevent system lockups from bcma during suspend/resume. Please let me know if there are problems!
