git://git.linaro.org/people/shawnguo/linux-2.6 into next/cleanup
From Shawn Guo:
The series cleans up ARCH_HAS_DECOMP_WDOG and arch_decomp_wdog which
are unused on ARM architecure. Samsung has some code setting up wdog
in arch_decomp_wdog(). But since CONFIG_S3C_BOOT_WATCHDOG is defined
nowhere, it will not run. Otherwise, system can not boot at all when
wdog is set up but no one pats it.

This allows clocksource drivers that support both DT and non-DT to
always invoke macro CLOCKSOURCE_OF_DECLARE(), rather than wrapping
it in a #ifdef CONFIG_CLKSRC_OF, which simplifies their code.

Commit 6bb27d7 "ARM: delete struct sys_timer" caused the following:
arch/arm/mach-imx/imx31-dt.c:56:2: warning: initialization from incompatible pointer type [enabled by default]
arch/arm/mach-imx/imx31-dt.c:56:2: warning: (near initialization for ‘__mach_desc_IMX31_DT.init_time’) [enabled by default]
This is because mx31_clocks_init_dt() returns int, whereas the .init_time
field prototype expects a function returning void. Implement a wrapper so
that the prototypes match.

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.

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.

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,

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,
