Josef Bacik 6d668dda0c Btrfs: make a delayed_block_rsv for the delayed item insertion
I've been hitting warnings in use_block_rsv when running the delayed insertion
stuff.  It's because we will readjust global block rsv based on what is in use,
which means we could end up discarding reservations that are for the delayed
insertion stuff.  So instead create a seperate block rsv for the delayed
insertion stuff.  This will also make it easier to debug problems with the
delayed insertion reservations since we will know that only the delayed
insertion code touches this block_rsv.  Thanks,

Chris Mason af31f5e5b8 Btrfs: add a log of past tree roots
This takes some of the free space in the btrfs super block
to record information about most of the roots in the last four
commits.

It also adds a -o recovery to use the root history log when
we're not able to read the tree of tree roots, the extent
tree root, the device tree root or the csum root.

David Sterba 6c41761fc6 btrfs: separate superblock items out of fs_info
fs_info has now ~9kb, more than fits into one page. This will cause
mount failure when memory is too fragmented. Top space consumers are
super block structures super_copy and super_for_commit, ~2.8kb each.
Allocate them dynamically. fs_info will be ~3.5kb. (measured on x86_64)

Add a wrapper for freeing fs_info and all of it's dynamically allocated
members.

Josef Bacik c8174313a8 Btrfs: use the global reserve when truncating the free space cache inode
We no longer use the orphan block rsv for holding the reservation for truncating

Josef Bacik 5a77d76c24 Btrfs: release metadata from global reserve if we have to fallback for unlink
I fixed a problem where we weren't reserving space for an orphan item when we
had to fallback to using the global reserve for an unlink, but I introduced
another problem.  I was migrating the bytes from the transaction reserve to the
global reserve and then releasing from the global reserve in
btrfs_end_transaction().  The problem with this is that a migrate will jack up
the size for the destination, but leave the size alone for the source, with the
idea that you can do a release normally on the source and it all washes out, and
then you can do a release again on the destination and it works out right.  My
way was skipping the release on the trans_block_rsv which still had the jacked
up size from our original reservation.  So instead release manually from the
global reserve if this transaction was using it, and then set the
trans->block_rsv back to the trans_block_rsv so that btrfs_end_transaction
cleans everything up properly.  With this patch xfstest 83 doesn't emit warnings
about leaking space.  Thanks,

Chris Mason 01d658f2ca Btrfs: make sure to flush queued bios if write_cache_pages waits
write_cache_pages tries to build up a large bio to stuff down the pipe.
But if it needs to wait for a page lock, it needs to make sure and send
down any pending writes so we don't deadlock with anyone who has the
page lock and is waiting for writeback of things inside the bio.

Dave Sterba triggered this as a deadlock between the autodefrag code and
the extent write_cache_pages

Chris Mason e688b7252f Btrfs: fix extent pinning bugs in the tree log
The tree log had two important bugs that could cause corruptions after a
crash.  Sometimes we were allowing tree log blocks to be reused after
the tree log was committed but before the transaction commit was done.

This allowed a future metadata write to overwrite the tree log data.  It
is fixed by adding a new variant of freeing reserved extents that always
pins them.  Credit goes to Stefan Behrens and Arne Jansen for many many
hours spent tracking this bug down.

During tree log replay, we do a pass through the tree log and pin all
the extents we find.  This makes sure the replay code won't go in and
use any of those blocks for new allocations during replay.  The problem
is the free space cache isn't honoring these pinned extents.  So the
allocator can end up handing them out, leading to all kinds of problems
during replay.

The fix here is to force any free space cache to load while we pin the
extents, and then to make sure we remove the pinned extents from the
free space rbtree.

Kukjin Kim 830145796a ARM: EXYNOS: Add ARCH_EXYNOS and reorganize arch/arm/mach-exynos
The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

Russell King 7a3f8de5a3 ARM: PXA: fix includes in pxa2xx_cm_x2xx PCMCIA driver
The includes in the pxa2xx_cm_x2xx PCMCIA driver are rather random;
the driver doesn't require anything from these headers except the
cpu_is_xxx() macros which come from another include.

The concern is that it's getting these definitions via mach/system.h,
which is supposed to only be included by arch/arm/kernel/process.c.
As this header is scheduled for cleanup (and elimination) keeping
the status quo will cause build errors.  So lets fix properly and

Wim Van Sebroeck deb9197b70 watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver
Jiri Slaby: 28d41f53f broke temperature sensors on a ICH10 chipset

The iTCO_wdt driver disables the SMI. This breaks good working of newer hardware.
The disabling of the SMI by the TCO logic dates back from the i810-tco driver
from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes
install handlers reset or disable the watchdog timer instead of resetting the system.
The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the
SMI_EN register) to prevent this from happening.

This however has strange effects on newer hardware. So we are in a situation that
a fix for broken old hardware affects newer hardware.

The correct solution is to make this fix an option (with the new module parameter:
turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version.

the next patch will be to move this in the start and stop functions of the driver
and to add a new module parameter for the global_smi_en bit and to get rid of the
vendor_support code.

This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that
have a broken BIOS implementation concerning TCO logic. In these case the module
parameter turn_SMI_watchdog_clear_off=1 will need to be added.

This is to exclude it from force threading to allow RT patch set to work.

The watchdog timers are per-CPU and the addresses of register that reset
the timer are calculated based on the current CPU.  Therefore we cannot
allow it to run on a thread on a different CPU.  Also we only do a
single register write, which is much faster than scheduling a handler
thread.

And while on this line remove IRQF_DISABLED as this flag is a NOP.

Dan McGee 5c8a0fbba5 VFS: fix statfs() automounter semantics regression
No one in their right mind would expect statfs() to not work on a
automounter managed mount point. Fix it.

[ I'm not sure about the "no one in their right mind" part.  It's not
  mounted, and you didn't ask for it to be mounted.  But nobody will
  really care, and this probably makes it match previous semantics, so..

This mirrors the fix made to the quota code in 815d405cef.

Tomi Valkeinen fc01387302 ARM: OMAP: change get_context_loss_count ret value to int
get_context_loss_count functions return context loss count as u32, and
zero means an error. However, zero is also returned when context has
never been lost and could also be returned when the context loss count
has wrapped and goes to zero.

Change the functions to return an int, with negative value meaning an
error.

OMAP HSMMC code uses omap_pm_get_dev_context_loss_count(), but as the
hsmmc code handles the returned value as an int, with negative value
meaning an error, this patch actually fixes hsmmc code also.
