  agp: add user mapping support to ATI AGP bridge.
  drm/i915: enable GEM on PAE.
  drm/radeon: fix unused variables warning
  agp: switch AGP to use page array instead of unsigned long array
  agpgart: detected ALi M???? chipset with M1621
  drm/radeon: command stream checker for r3xx-r5xx hardware
  drm/radeon: Fully initialize LVDS info also when we can't get it from the ROM.
  radeon: Fix CP byte order on big endian architectures with KMS.
  agp/uninorth: Handle user memory types.
  drm/ttm: Add some powerpc cache flush code.
  radeon: Enable modesetting on non-x86.
  drm/radeon: Respect AGP cant_use_aperture flag.
  drm: EDID endianness fixes.
  drm/radeon: this VRAM vs aperture test is wrong, just remove it.
  drm/ttm: fix an error path to exit function correctly
  drm: Apply "Memory fragmentation from lost alignment blocks"
  ttm: Return -ERESTART when a signal interrupts bo eviction.
  drm: Remove memory debugging infrastructure.
