2009-07-08PM: Clear -EAGAIN in dpm_prepareSebastian Ott1-0/+1
When the last device in the dpm list is unregistered directly after its prepare() callback returned with -EAGAIN, the return code is passed to the calling function, resulting in a suspend failure.

2009-07-08x86: Fix resume from suspend when CONFIG_CC_STACKPROTECTORPeter Chubb1-1/+1
Patch 08687aec71bc9134fe336e561f6did877bacf74fc0a (x86: unify power/cpu_(32|64).c) renamed cpu_32.c to cpu.c, but did not update the special compilation flags for the file for the new name. This patch fixes the compilation flags, and therefore fixes resume from suspend on my Acer Aspire One.

2009-07-07Input: mark serio and i8042 as suspended when hibernating tooThadeu Lima de Souza Cascardo2-6/+8
Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.

2009-07-08powerpc: Fix spin_event_timeout() to be robust over context switchesGrant Likely1-0/+2
Current implementation of spin_event_timeout can be interrupted by an IRQ or context switch after testing the condition, but before checking the timeout. This can cause the loop to report a timeout when the condition actually became true in the middle. This patch adds one final check of the condition upon exit of the loop if the last test of the condition was still false.

2009-07-07mac80211: minstrel: avoid accessing negative indices in rix_to_ndx()Luciano Coelho1-1/+4
If rix is not found in mi->r[], i will become -1 after the loop.

2009-07-07ath9k: Fix leak in tx descriptorVasanthakumar Thiagarajan1-1/+8
When we reclaim the tx desc, we always assume that the last desc is a holding desc, which is not true, and skip it. If the tx queue is drained during channel change, internal reset and etc, the last descriptor may not be the holding descriptor and we fail to reclaim them. This results in the following two issues. 1. Tx stuck - We drop all the frames coming from upper layer due to shortage in tx desc. 2. Crash - If we fail to reclaim a tx descriptor, we miss to update the tx BA window with the seq number of the frame associated to that desc, which, at some point, result in the following crash due to an assert failure in ath_tx_addto_baw(). This patch fixes these two issues. kernel BUG at ../drivers/net/wireless/ath/ath9k/xmit.c:180!

2009-07-07quota: Fix possible deadlock during parallel quotaon and quotaoffJiaying Zhang1-2/+2
The following test script triggers a deadlock on ext2 filesystem: while true; do quotaon /dev/hda >&/dev/null; usleep $RANDOM; done & while true; do quotaoff /dev/hda >&/dev/null; usleep $RANDOM; done & I found there is a potential deadlock between quotaon and quotaoff (or quotasync). Basically, all of quotactl operations need to be protected by dqonoff_mutex. vfs_quota_off and vfs_quota_sync also call sb->s_op->quota_write that needs to grab the i_mutex of the quota file. But in vfs_quota_on_inode (called from quotaon operation), the current code tries to grab the i_mutex of the quota file first before getting quonoff_mutex. Reverse the order in which we take locks in vfs_quota_on_inode(). Jan Kara: Changed changelog to be more readable, made lockdep happy with I_MUTEX_QUOTA.
