Merge branch 'drm-core-next' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6

* 'drm-core-next' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (476 commits)
  vmwgfx: Implement a proper GMR eviction mechanism
  drm/radeon/kms: fix r6xx/7xx 1D tiling CS checker v2
  drm/radeon/kms: properly compute group_size on 6xx/7xx
  drm/radeon/kms: fix 2D tile height alignment in the r600 CS checker
  drm/radeon/kms/evergreen: set the clear state to the blit state
  drm/radeon/kms: don't poll dac load detect.
  gpu: Add Intel GMA500(Poulsbo) Stub Driver
  drm/radeon/kms: MC vram map needs to be >= pci aperture size
  drm/radeon/kms: implement display watermark support for evergreen
  drm/radeon/kms/evergreen: add some additional safe regs v2
  drm/radeon/r600: fix tiling issues in CS checker.
  drm/i915: Move gpu_write_list to per-ring
  drm/i915: Invalidate the to-ring, flush the old-ring when updating domains
  drm/i915/ringbuffer: Write the value passed in to the tail register
  agp/intel: Restore valid PTE bit for Sandybridge after bdd3072
  drm/i915: Fix flushing regression from 9af90d19f
  drm/i915/sdvo: Remove unused encoding member
  i915: enable AVI infoframe for intel_hdmi.c [v4]
  drm/i915: Fix current fb blocking for page flip
  drm/i915: IS_IRONLAKE is synonymous with gen == 5
  ...

Fix up conflicts in
 - drivers/gpu/drm/i915/{i915_gem.c, i915/intel_overlay.c}: due to the
   new simplified stack-based kmap_atomic() interface
 - drivers/gpu/drm/vmwgfx/vmwgfx_drv.c: added .llseek entry due to BKL
   removal cleanups.
