Currently all boards must explicitly disable all unused device tree
nodes of unused components (e.g. i2c, sdhci, etc...). This makes it
necessary to all boards to be aware of all components on the SoC, which
in turns makes board dts files longer and more difficult to maintain
(e.g. adding new components to SoC-level tree requires adding nodes with
status="disabled" to every board).

This patch changes "status" of all optional components in SoC-level dts
file to "disabled", adds status="okay" to respective nodes of used
components in dts of all boards and removes all nodes with only
status="disabled" from boards dts.

This reverts commit 970e1789.

Nikolay Ulyanitsky reported thatthe 3.6-rc5 kernel has a 15-20%
performance drop on PostgreSQL 9.2 on his machine (running "pgbench").

Borislav Petkov was able to reproduce this, and bisected it to this
commit 970e1789 ("sched: Improve scalability via 'CPU buddies' ...")
apparently because the new single-idle-buddy model simply doesn't find
idle CPU's to reschedule on aggressively enough.

Mike Galbraith suspects that it is likely due to the user-mode spinlocks
in PostgreSQL not reacting well to preemption, but we don't really know
the details - I'll just revert the commit for now.

There are hopefully other approaches to improve scheduler scalability
without it causing these kinds of downsides.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties.  This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern.  There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.

Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts.  The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

ASoC: Updates for 3.6

A bigger set of updates than I'm entirely comfortable with - things
backed up a bit due to travel.  As ever the majority of these are small,
focused updates for specific drivers though there are a couple of core
changes.  There's been good exposure in -next.

The AT91 patch fixes a build break.

Pull GFS2 fixes from Steven Whitehouse:
 "Here are three GFS2 fixes for the current kernel tree.  These are all
  related to the block reservation code which was added at the merge
  window.  That code will be getting an update at the forthcoming merge
  window too.  In the mean time though there are a few smaller issues
  which should be fixed.

  The first patch resolves an issue with write sizes of greater than 32
  bits with the size hinting code.  The second ensures that the
  allocation data structure is initialised when using xattrs and the
  third takes into account allocations which may have been made by other
  nodes which affect a reservation on the local node."

* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes:
  GFS2: Take account of blockages when using reserved blocks
  GFS2: Fix missing allocation data for set/remove xattr
  GFS2: Make write size hinting code common

Pull x86 platform driver updates from Matthew Garrett:
 "A few small updates for 3.6 - a trivial regression fix and a couple of
  conformance updates for the gmux driver, plus some tiny fixes for
  asus-wmi, eeepc-laptop and thinkpad_acpi."

* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
  thinkpad_acpi: buffer overflow in fan_get_status()
  eeepc-laptop: fix device reference count leakage in eeepc_rfkill_hotplug()

 - Fixes a regression, introduced in 3.6-rc1, when a file is closed
   before its shared memory mapping is dirtied and unmapped.  The lower

   dirtied pages could not be written out.
 - Adds a call to the lower filesystem's ->flush() from
   ecryptfs_flush().
 - Fixes a regression, introduced in 2.6.39, when a file is renamed on
   top of another file.  The target file's inode was not being evicted
   and the space taken by the file was not reclaimed until eCryptfs was
   unmounted.
