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.
