2011-11-15tty: hvc_dcc: Fix duplicate character inputsStephen Boyd
Reading from the DCC grabs a character from the buffer and clears the status bit. Since this is a context-changing operation, instructions following the character read that rely on the status bit being accurate need to be synchronized with an ISB. In this case, the status bit check needs to execute after the character read otherwise we run the risk of reading the character and checking the status bit before the read can clear the status bit in the first place. When this happens, the user will see the same character they typed twice, instead of once. Add an ISB after the read and the write, so that the status check is synchronized with the read/write operations.

2011-11-15pch_phub: Fix MAC address writing issue for LAPIS ML7831Tomoya MORINAGA
ISSUE: Using ML7831, MAC address writing doesn't work well. CAUSE: ML7831 and EG20T have the same register map for MAC address access. However, this driver processes the writing the same as ML7223. This is not true. This driver must process the writing the same as EG20T. This patch fixes the issue.

Lockdep reports there is potential deadlock for slub node list_lock. discard_slab() is called with the lock hold in unfreeze_partials(), which could trigger a slab allocation, which could hold the lock again. discard_slab() doesn't need hold the lock actually, if the slab is already removed from partial list.

2011-11-15rt2x00: Fix sleep-while-atomic bug in powersaving code.Gertjan van Wingerde
The generic powersaving code that determines after reception of a frame whether the device should go back to sleep or whether is could stay awake was calling rt2x00lib_config directly from RX tasklet context. On a number of the devices this call can actually sleep, due to having to confirm that the sleeping commands have been executed successfully. Fix this by moving the call to rt2x00lib_config to a workqueue call.

2011-11-15Btrfs: fix tree corruption after multi-thread snapshots and inode_cache flushLiu Bo
The btrfs snapshotting code requires that once a root has been snapshotted, we don't change it during a commit. But there are two cases to lead to tree corruptions: 1) multi-thread snapshots can commit serveral snapshots in a transaction, and this may change the src root when processing the following pending snapshots, which lead to the former snapshots corruptions; 2) the free inode cache was changing the roots when it root the cache, which lead to corruptions. This fixes things by making sure we force COW the block after we create a snapshot during commiting a transaction, then any changes to the roots will result in COW, and we get all the fs roots and snapshot roots to be consistent.

2011-11-14sparc: Fix handling of orig_i0 wrt. debugging when restarting syscalls.David S. Miller
Although we provide a proper way for a debugger to control whether syscall restart occurs, we run into problems because orig_i0 is not saved and restored properly. Luckily we can solve this problem without having to make debuggers aware of the issue. Across system calls, several registers are considered volatile and can be safely clobbered. Therefore we use the pt_regs save area of one of those registers, %g2, as a place to save and restore orig_i0. Debuggers transparently will do the right thing because they save and restore this register already. Signed-off-by: David S. Miller <davem@davemloft.net>
