It contains a variety of fixes for problems discovered during the merge window and after 3.10-rc1. For the mac80211 bits, Johannes says the following: "This is what I have: * a patch from Felix to fix RCU usage in his rate table code * a patch from Ilan to add the wdev id to some notifications so they can actually be used by userspace * Sasha Levin found an issue in how hwsim handles devices * a fix for a bug in the wiphy_register() error path that's been there for= ever * three fixes for WoWLAN * AP mode frame matching was erroneously giving frames to all virtual AP interfaces (reported by Jouni) * a fix for HT handling in my CSA changes, found by Sujith * a fix for some locking simplifications gone wrong * Ben Greear found more cfg80211/mac80211 state confusion * and a fix for another bug found by Jouni: local state changes need to be reported by mac80211 to cfg80211 so it disconnects properly." And for the iwlwifi bits, he says: "I have fixes for a firmware crash during resume, multicast RX, aggregation and a workaround for a firmware scanning bug." Along with those... Albert Pool adds a USB ID to the rtl8192cu driver. Arend van Spriel restores a driver option support flag that had been removed from 3.9 due to a bug in that version of the driver. Felix Fietkau fixes a trio of ath9k issues with a series of small patches. Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also merged, so it isn't in the diff here). Larry Finger gives us a fix for a build warning on big-endian systems for rtlwifi. Rafa=C5=82 Mi=C5=82ecki adds some core IDs to the bcma driver. Sujith Manoharan fixes a module unloading crash in ath9k, and corrects some calibration settings for AR9485. Please let me know if there are problems!
