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

* 'drm-patches' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (36 commits)
  drm: Use register writes instead of BITBLT_MULTI packets for buffer swap blits
  drm: use radeon specific names for radeon flags
  drm: add device/vendor id to drm_device_t for compat with FreeBSD drivers
  drm: allow multiple addMaps with the same 32-bit map offsset.
  drm: fd.o Bug #7595: Avoid u32 overflows in radeon_check_and_fixup_offset().
  drm: Fix hashtab implementation leaking illegal error codes to user space.
  drm: domain changes broke ppc r200
  drm: fixup setversion return codes..
  drm: fixup i915 error codes
  drm: realign sosme radeon code with drm git tree
  drm: realign via driver with drm git tree
  drm: remove hash tables on drm exit
  drm: cleanups
  drm: i810_dma.c: fix pointer arithmetic for 64-bit target
  drm: avoid kernel oops in some error paths calling drm_lastclose
  drm: allow detection of new VIA chipsets
  drm: fix i965 build bug
  drm: remove FALSE/TRUE that snuck in with simple memory manager changes.
  drm: Add support for Intel i965G chipsets.
  drm: add better explanation for i830/i915
