ASoC: Updates for v3.11

Not a big release subsystem wise, the main changes have been some nice
improvements on the driver side:

- Lots of cleanups and fixes for Blackfin, SGTL5000 and UX500.
- Generalisation of the Bluetooth and HDMI stub drivers.
- New CODEC drivers for SSM2518 and RT5640.
- New machine driver for Tegra CPUs with RT5640.

Pull more xfs updates from Ben Myers:
 "Here are several fixes for filesystems with CRC support turned on:
  fixes for quota, remote attributes, and recovery.  There is also some
  feature work related to CRCs: the implementation of CRCs for the inode
  unlinked lists, disabling noattr2/attr2 options when appropriate, and
  bumping the maximum number of ACLs.

  I would have preferred to defer this last category of items to 3.11.
  This would require setting a feature bit for the on-disk changes, so
  there is some pressure to get these in 3.10.  I believe this
  represents the end of the CRC related queue.

   - Rework of dquot CRCs
   - Fix for remote attribute invalidation of a leaf
   - Fix ordering of transaction replay in recovery
   - Implement CRCs for inode unlinked list
   - Disable noattr2/attr2 mount options when CRCs are enabled
   - Bump the limitation of ACL entries for v5 superblocks"

2b3f8e87cf powerpc/tm: Fix userspace stack corruption on signal delivery for active transactions
When in an active transaction that takes a signal, we need to be careful with
the stack.  It's possible that the stack has moved back up after the tbegin.
The obvious case here is when the tbegin is called inside a function that
returns before a tend.  In this case, the stack is part of the checkpointed
transactional memory state.  If we write over this non transactionally or in
suspend, we are in trouble because if we get a tm abort, the program counter
and stack pointer will be back at the tbegin but our in memory stack won't be
valid anymore.

To avoid this, when taking a signal in an active transaction, we need to use
the stack pointer from the checkpointed state, rather than the speculated
state.  This ensures that the signal context (written tm suspended) will be
written below the stack required for the rollback.  The transaction is aborted
becuase of the treclaim, so any memory written between the tbegin and the
signal will be rolled back anyway.

For signals taken in non-TM or suspended mode, we use the
normal/non-checkpointed stack pointer.

Tested with 64 and 32 bit signals

6ce6c629fd powerpc/tm: Abort on emulation and alignment faults
If we are emulating an instruction inside an active user transaction that
touches memory, the kernel can't emulate it as it operates in transactional
suspend context.  We need to abort these transactions and send them back to
userspace for the hardware to rollback.

We can service these if the user transaction is in suspend mode, since the
kernel will operate in the same suspend context.

This adds a check to all alignment faults and to specific instruction
emulations (only string instructions for now).  If the user process is in an
active (non-suspended) transaction, we abort the transaction go back to
userspace allowing the HW to roll back the transaction and tell the user of the
failure.  This also adds new tm abort cause codes to report the reason of the
persistent error to the user.

Crappy test case here http://neuling.org/devel/junkcode/aligntm.c

26549c8d36 drivers/video: implement a simple framebuffer driver
A simple frame-buffer describes a raw memory region that may be rendered
to, with the assumption that the display hardware has already been set
up to scan out from that buffer.

This is useful in cases where a bootloader exists and has set up the
display hardware, but a Linux driver doesn't yet exist for the display
hardware.

Examples use-cases include:

* The built-in LCD panels on the Samsung ARM chromebook, and Tegra
  devices, and likely many other ARM or embedded systems.  These cannot
  yet be supported using a full graphics driver, since the panel control
  should be provided by the CDF (Common Display Framework), which has been
  stuck in design/review for quite some time.  One could support these
  panels using custom SoC-specific code, but there is a desire to use
  common infra-structure rather than having each SoC vendor invent their
  own code, hence the desire to wait for CDF.

* Hardware for which a full graphics driver is not yet available, and
  the path to obtain one upstream isn't yet clear.  For example, the
  Raspberry Pi.

* Any hardware in early stages of upstreaming, before a full graphics
  driver has been tackled.  This driver can provide a graphical boot
  console (even full X support) much earlier in the upstreaming process,
  thus making new SoC or board support more generally useful earlier.

37d46e152e xen/tmem: Don't use self[ballooning|shrinking] if frontswap is off.
There is no point. We would just squeeze the guest to put more and
more pages in the swap disk without any purpose.

The only time it makes sense to use the selfballooning and shrinking
is when frontswap is being utilized.

2ca62b0444 xen/tmem: Remove the boot options and fold them in the tmem.X parameters.
If tmem is built-in or a module, the user has the option on
the command line to influence it by doing: tmem.<some option>
instead of having a variety of "nocleancache", and
"nofrontswap". The others: "noselfballooning" and "selfballooning";
and "noselfshrink" are in a different driver xen-selfballoon.c
and the patches:

 xen/tmem: Remove the usage of 'noselfshrink' and use 'tmem.selfshrink' bool instead.
 xen/tmem: Remove the usage of 'noselfballoon','selfballoon' and use 'tmem.selfballon' bool instead.

remove them.

Also add documentation.

fe0a797a6b bcache: clarify free/available/unused space
Don't describe bcache_available_percent as free space but as
non-writeback space.  Describe priority_stats in more detail
and point to that for total bcache occupation.

86fd03d160 PM / Documentation: remove inaccurate suspend/hibernate transition lantency statement
The lantency of the transition from suspend and hibernate is
platform-dependent.  Thus we should not refer the lantency in the
documentation.

62477adf5f ASoC: mxs: move to use generic DMA helper
With mxs-dma converted to generic DMA bindings, let's move mxs-pcm to
use it by removing flages SND_DMAENGINE_PCM_FLAG_NO_DT and
SND_DMAENGINE_PCM_FLAG_COMPAT.  As the result, those mxs custom dma
params code can be removed now.
