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

* 'drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
  drm: Avoid oops in DRM_IOCTL_RM_DRAW if a bad handle is supplied.
  drm: Add 32-bit compatibility for DRM_IOCTL_UPDATE_DRAW.
  drm/i915: use pipes, not planes to label vblank data
  drm/i915: hold dev->struct_mutex and DRM lock during vblank ring operations
  i915: Fix format string warnings on x86-64.
  i915: Don't dereference HWS in /proc debug files when it isn't initialized.
  i915: Enable IMR passthrough of vblank events before enabling it in pipestat.
  drm: Remove two leaks of vblank reference count in error paths.
  drm: fix leak of cliprects in drm_rmdraw()
  i915: Disable MSI on GM965 (errata says it doesn't work)
  drm: Set cliprects to NULL when changing drawable to having 0 cliprects.
  i915: Protect vblank IRQ reg access with spinlock
