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

* 'drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
  amd64-agp: fix crash at second module load
  drm/radeon: fix regression with AA resolve checking
  drm: drop commented out code and preceding comment
  drm/vblank: Enable precise vblank timestamps for interlaced and doublescan modes.
  drm/vblank: Use memory barriers optimized for atomic_t instead of generics.
  drm/vblank: Use abs64(diff_ns) for s64 diff_ns instead of abs(diff_ns)
  drm/radeon/kms: align height of fb allocation.
  Revert "drm/radeon/kms: switch back to min->max pll post divider iteration"
