* 'drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6: (44 commits)
  drm/i915: fix ioremap of a user address for non-root (CVE-2008-3831)
  drm: make CONFIG_DRM depend on CONFIG_SHMEM.
  radeon: fix PCI bus mastering support enables.
  radeon: add RS400 family support.
  drm/radeon: add support for RS740 IGP chipsets.
  i915: GM45 has GM965-style MCH setup.
  i915: Don't run retire work handler while suspended
  i915: Map status page cached for chips with GTT-based HWS location.
  i915: Fix up ring initialization to cover G45 oddities
  i915: Use non-reserved status page index for breadcrumb
  drm: Increment dev_priv->irq_received so i915_gem_interrupts count works.
  drm: kill drm_device->irq
  drm: wbinvd is cache coherent.
  i915: add missing return in error path.
  i915: fixup permissions on gem ioctls.
  drm: Clean up many sparse warnings in i915.
  drm: Use ioremap_wc in i915_driver instead of ioremap, since we always want WC.
  drm: G33-class hardware has a newer 965-style MCH (no DCC register).
  drm: Avoid oops in GEM execbuffers with bad arguments.
  DRM: Return -EBADF on bad object in flink, and return curent name if it exists.
