63fc1370c1 ARM: highbank: mask cluster id from cpu_logical_map
With commit a0ae0240 (ARM: kernel: add device tree init map function),
the cpu id value may include the cluster id and is no longer 0-3, so we
need to mask it now to get the right hard cpu index.

c7d5b93e98 ARM: scu: mask cluster id from cpu_logical_map
With commit a0ae0240 (ARM: kernel: add device tree init map function),
the cpu id value may include the cluster id and is no longer 0-3, so we
need to mask it in scu_power_mode to get the local cpu number. Since we
are only dealing with the cpu we are running on, the cluster id should
not ever be needed.

 "It turns out that we had two crc bugs when running fsx-linux in a
  loop.  Many thanks to Josef, Miao Xie, and Dave Sterba for nailing it

  Ilya fixed a regression Liu Bo found in the balance ioctls for pausing
  and resuming a running balance across drives.

  Josef's orphan truncate patch fixes an obscure corruption we'd see
  during xfstests.

  Arne's patches address problems with subvolume quotas.  If the user
  destroys quota groups incorrectly the FS will refuse to mount.

  The rest are smaller fixes and plugs for memory leaks."

Here's a long-pending fixes pull request for arm-soc (I didn't send one

 The larger deltas are from:
 - A fixup of error paths in the mvsdio driver
 - Header file move for a driver that hadn't been properly converted to
   multiplatform on i.MX, which was causing build failures when included
 - Device tree updates for at91 dealing mostly with their new
   pinctrl setup merged in 3.8 and mistakes in those initial configs
 
 The rest are the normal mix of small fixes all over the place; sunxi,
 omap, imx, mvebu, etc, etc.

1eafa6c737 Btrfs: fix repeated delalloc work allocation
btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the
first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/
btrfs_queue_worker for this inode, and then it locks the list, checks the
head of the list again. But because we don't delete the first inode that it
deals with before, it will fetch the same inode. As a result, this function
allocates a huge amount of btrfs_delalloc_work structures, and OOM happens.

Fix this problem by splice this delalloc list.

2cba30f172 Btrfs: fix missed transaction->aborted check
First, though the current transaction->aborted check can stop the commit early
and avoid unnecessary operations, it is too early, and some transaction handles
don't end, those handles may set transaction->aborted after the check.

Second, when we commit the transaction, we will wake up some worker threads to
flush the space cache and inode cache. Those threads also allocate some transaction
handles and may set transaction->aborted if some serious error happens.

So we need more check for ->aborted when committing the transaction. Fix it.

e58dd74bcc Btrfs: put csums on the right ordered extent
I noticed a WARN_ON going off when adding csums because we were going over
the amount of csum bytes that should have been allowed for an ordered
extent.  This is a leftover from when we used to hold the csums privately
for direct io, but now we use the normal ordered sum stuff so we need to
make sure and check if we've moved on to another extent so that the csums
are added to the right extent.  Without this we could end up with csums for
bytenrs that don't have extents to cover them yet.  Thanks,

b0175117b9 Btrfs: fix panic when recovering tree log
A user reported a BUG_ON(ret) that occured during tree log replay.  Ret was
-EAGAIN, so what I think happened is that we removed an extent that covered
a bitmap entry and an extent entry.  We remove the part from the bitmap and
return -EAGAIN and then search for the next piece we want to remove, which
happens to be an entire extent entry, so we just free the sucker and return.
The problem is ret is still set to -EAGAIN so we trip the BUG_ON().  The
user used btrfs-zero-log so I'm not 100% sure this is what happened so I've
added a WARN_ON() to catch the other possibility.  Thanks,

We drop the extent map tree lock while we're logging extents, so somebody

logging the extent or freeing our ref on it, so we need to make sure to not
clear LOGGING until after the extent is logged, and then we can merge it to
