2011-01-04ath9k_htc: Fix fast channel changeSujith Manoharan
When returning to the operating channel, a full HW reset has to be done instead of a fast channel change. Since sw_scan_complete() is called after the config() call for the home channel, we end up doing a FCC. Fix this issue by checking the OFFCHANNEL flag to determine FCC.

2011-01-04ath9k_htc: Handle pending URBs properlySujith Manoharan
When doing a channel change, the pending URBs have to be killed properly on calling htc_stop(). This fixes the probe response timeout seen when sending UDP traffic at a high rate and running background scan at the same time.

2011-01-04mac80211: ignore PSM bit of reordered framesChristian Lamparter
This patch tackles one of the problems of my reorder release timer patch from August. <http://www.spinics.net/lists/linux-wireless/msg57214.html> => What if the reorder release triggers and ap_sta_ps_end (called by ieee80211_rx_h_sta_process) accidentally clears the WLAN_STA_PS_STA flag, because 100ms ago - when the STA was still active - frames were put into the reorder buffer.

This patch revamps some common code-paths which are shared between (re-)initialization and suspend/resume subroutines. It also adds some helpful comments about quirks and associated difficulties. It's quite big, but it should fix #25382: <https://bugzilla.kernel.org/show_bug.cgi?id=25382> And hopefully the code is robust enough to deal with all possible suspend/resume scenarios without requiring the user to do any sort of manual and possibly dangerous work.

2011-01-04SPARC/LEON: added support for IRQAMP IRQ ControllerDaniel Hellstrom
Needed for LEON AMP systems where different CPUs are routed to different IRQ controllers. This patch selects the IRQ Controller which has been routed to the boot CPU, it is up to the boot loader to configure the IRQ controller.

2011-01-04iwlagn: enable only rfkill interrupt when device is downStanislaw Gruszka
Since commit 6cd0b1cb872b3bf9fc5de4536404206ab74bafdd "iwlagn: fix hw-rfkill while the interface is down", we enable interrupts when device is not ready to receive them. However hardware, when it is in some inconsistent state, can generate other than rfkill interrupts and crash the system. I can reproduce crash with "kernel BUG at drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing firmware restarts. To fix only enable rfkill interrupt when down device and after probe. I checked patch on laptop with 5100 device, rfkill change is still passed to user space when device is down.
