Amit Shah f878d0be22 virtio-pci: switch to PM ops macro to initialise PM functions
Use the SET_SYSTEM_SLEEP_PM_OPS macro to initialise the suspend/resume
functions in the new PM API.

Amit Shah 04c2322bee virtio-pci: S3 support
There's no difference in supporting S3 and S4 for virtio devices: the
vqs have to be re-created as the device has to be assumed to be reset at
restore-time.  Since S4 already handles this situation, we can directly
use the same code and callbacks for S3 support.

Amit Shah 0517fdd156 virtio-pci: drop restore_common()
restore_common() was shared between restore and thaw callbacks.  With
thaw gone, we don't need restore_common() anymore.

Amit Shah f38f8387cb virtio: drop thaw PM operation
The thaw operation was used by the balloon driver, but after the last

Amit Shah e47d854e57 virtio: balloon: Allow stats update after restore from S4
There's no reason stats update after restore can't work.  If a host
requested for stats, and before servicing the request, the guest entered
S4, upon restore, the stats request can still be processed and sent off
to the host.

Merge tag 'for-linus-3.4' of git://git.infradead.org/mtd-2.6

Pull MTD changes from David Woodhouse:
 - Artem's cleanup of the MTD API continues apace.
 - Fixes and improvements for ST FSMC and SuperH FLCTL NAND, amongst
   others.
 - More work on DiskOnChip G3, new driver for DiskOnChip G4.
 - Clean up debug/warning printks in JFFS2 to use pr_<level>.

Fix up various trivial conflicts, largely due to changes in calling
conventions for things like dmaengine_prep_slave_sg() (new inline
wrapper to hide new parameter, clashing with rewrite of previously last
parameter that used to be an 'append' flag, and is now a bitmap of
'unsigned long flags').

(Also some header file fallout - like so many merges this merge window -
and silly conflicts with sparse fixes)

Lucas De Marchi 78286cdf05 Documentation: replace install commands with softdeps
Install commands should not be used to specify soft dependencies among
modules. When loading modules it's much better to have a softdep that
modprobe knows what's being done than having to fork/exec another
instance of modprobe to load the other module.

By using a softdep user has also an option to remove the dependencies
when removing the module (and if its refcount dropped to 0)

This does a sweeping change fixing up all the missing system_misc.h and
system_info.h includes from the system.h split-up change. These were the
ones I came across when building all defconfigs in arch/arm/configs, there
might be more but they lack adequate build coverage to be easily caught.

I'm expecting to get a lot of these piecemeal by each maintainer, so we
might just as well do one sweeping change to get them all at once.

Jiang Liu f5cb92ac82 genirq: Adjust irq thread affinity on IRQ_SET_MASK_OK_NOCOPY return value
irq_move_masked_irq() checks the return code of
chip->irq_set_affinity() only for 0, but IRQ_SET_MASK_OK_NOCOPY is
also a valid return code, which is there to avoid a redundant copy of
the cpumask. But in case of IRQ_SET_MASK_OK_NOCOPY we not only avoid
the redundant copy, we also fail to adjust the thread affinity of an
eventually threaded interrupt handler.

Handle IRQ_SET_MASK_OK (==0) and IRQ_SET_MASK_OK_NOCOPY(==1) return
values correctly by checking the valid return values seperately.

Dan Carpenter 344e222edf ACPI throttling: fix endian bug in acpi_read_throttling_status()
Using a u64 here creates an endian bug.  We store a u32 number in the
top byte which is a larger number than intended on big endian systems.
There is no reason to use a 64 bit data type here, I guess it was just
an oversight.

I removed the initialization to zero as well.  It's needed with a u64
but with a u32, the variable gets initialized properly inside the call
to acpi_os_read_port().

On a system on the thermal limit these are quite noisy and flood the logs.
Better would be a counter anyways. But given that we don't even have

Igor Murzov b60e7f6166 ACPI video: Don't start video device until its associated input device has been allocated
Quoth Dmitry Torokhov:
In addition to bus notifier we do install device notifier explicitly
so it might fire up early. The easiest fox would be to move
acpi_video_bus_start_devices() after input_allocate_device() but
before input_register_device() - unregistered input devices can handle
input_event() calls just fine.

Linus Torvalds 9613bebb22 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes and features from Chris Mason:
 "We've merged in the error handling patches from SuSE.  These are
  already shipping in the sles kernel, and they give btrfs the ability
  to abort transactions and go readonly on errors.  It involves a lot of
  churn as they clarify BUG_ONs, and remove the ones we now properly
  deal with.

  Josef reworked the way our metadata interacts with the page cache.
  page->private now points to the btrfs extent_buffer object, which
  makes everything faster.  He changed it so we write an whole extent
  buffer at a time instead of allowing individual pages to go down,,
  which will be important for the raid5/6 code (for the 3.5 merge
  window ;)

  Josef also made us more aggressive about dropping pages for metadata
  blocks that were freed due to COW.  Overall, our metadata caching is
  much faster now.

  We've integrated my patch for metadata bigger than the page size.
  This allows metadata blocks up to 64KB in size.  In practice 16K and
  32K seem to work best.  For workloads with lots of metadata, this cuts
  down the size of the extent allocation tree dramatically and fragments
  much less.

  Scrub was updated to support the larger block sizes, which ended up
  being a fairly large change (thanks Stefan Behrens).

  We also have an assortment of fixes and updates, especially to the
  balancing code (Ilya Dryomov), the back ref walker (Jan Schmidt) and
  the defragging code (Liu Bo)."

Fixed up trivial conflicts in fs/btrfs/scrub.c that were just due to
removal of the second argument to k[un]map_atomic() in commit
7ac687d9e0.
