Merge branch 'drm-next-3.13' of git://people.freedesktop.org/~agd5f/linux into drm-fixes 

More fixes for radeon.  This adds new queries for tiling on CIK, and
fixes a crash in handling acpi atif backlight events on CIK.
Some fixes for radeon for 3.13.  Mostly CI stability fixes.  I think
I've tracked down the stability problems with dpm on Trinity/Richland,
so I'm going to enable that by default now.

* 'drm-next-3.13' of git://people.freedesktop.org/~agd5f/linux:
  drm/radeon: hook up backlight functions for CI and KV family.
  drm/radeon/cik: Add macrotile mode array query
  drm/radeon/cik: Return backend map information to userspace
  drm/radeon: enable DPM by default in TN asics
  drm/radeon: adjust TN dpm parameters for stability (v2)
  drm/radeon: use a single doorbell for cik kms compute
  drm/radeon/vm: don't attempt to update ptes if ib allocation fails
  drm/radeon: disable CIK CP semaphores for now
  drm/radeon: allow semaphore emission to fail
  drm/radeon: add semaphore trace point
  radeon: workaround pinning failure on low ram gpu
  radeon/i2c: do not count reg index in number of i2c byte we are writing.
  drm/radeon: cypress_dpm: Fix unused variable warning when CONFIG_ACPI=n
  drm: radeon: ni_dpm: Fix unused variable warning when CONFIG_ACPI=n
