A performance regression was introduced in TTM in linux 3.13 when we started using
VM_PFNMAP for shared mappings. In theory this should've been faster due to
less page book-keeping but it appears like VM_PFNMAP + x86 PAT + write-combine
is a particularly cpu-hungry combination, as seen by largely increased
cpu-usage on r200 GL video playback.

Until we've sorted out why, revert to always use VM_MIXEDMAP.

Without this, a bo may get created in the cpu-inaccessible vram.
Before the CP engines get setup, all copies are done via cpu memcpy.

This means that the cpu tries to read from inaccessible memory, fails,
and the radeon module proceeds to disable acceleration.

Doing this has no downsides, as the real VRAM size gets set as soon as the
CP engines get init.

This is a candidate for 3.14 fixes.

We reserve the space for the power context in stolen memory at a fixed
address from a delayed work. This races with the subsequent driver
init/resume code which could allocate something at that address, so the
reservation for the power context fails. Reserve the space up-front, so
this can't happen. This also adds a missing struct_mutex lock around the
stolen allocation, which wasn't taken in the delayed work path.

  drm/vmwgfx: avoid null pointer dereference at failure paths

  drm/vmwgfx: Remove some unused surface formats

vmw_takedown_otable_base() and vmw_mob_unbind() check for
potential vmw_fifo_reserve() failure and print error message,
but then immediately dereference NULL pointer.

Backing mob contents is propagated to user-space, so make sure backing
mobs are cleared when allocated. This also accidently fix rendering errors
with celestia when emulating legacy mode.

Also update driver date.

Pull ACPI and power management fixes from Rafael Wysocki:
 "These three commits fix a recent intel_pstate regression and two old
  bugs that should be fixed in -stable too, one in the ACPI processor
  driver and one in the firmare loader.

  Specifics:

   - One of the recent intel_pstate driver fixes introduced a rounding
     error that on some systems causes the frequency to be stuck at the
     lowest level forever.  Fix from Dirk Brandewie.

   - The firmware_class driver's PM notifier doesn't handle the
     PM_RESTORE_PREPARE event during hibernation image restore and that
     leads to a deadlock on umhelper_sem in __usermodehelper_disable().
     Fix from Sebastian Capella.

   - acpi_processor_set_throttling() abuses set_cpus_allowed_ptr() in a
     nasty way which triggers the WARN_ON_ONCE() in wq_worker_waking_up()
     among other things.  Fix from Lan Tianyu"

Fourth set of IIO fixes for the 3.14 kernel.

A single line patch fixing a regression that was introduced in 3.13 in the
reworking of the mxs touch screen and ADC drivers to be interrupt rather
than polling driven.  It resulted in a stray double reporting of the release
coordinate in the touch screen driver.  The bug lay in the adc side
of the driver which left the statemachine in the wrong state.
