This time in time! Just 32bit-pae fix from Hugh, semaphores fun from Chris
and a fix for runtime pm cherry-picked from next.

Paulo is still working on a fix for runtime pm when X does cursor fun when
the display is off, but that one isn't ready yet.

  drm/i915: Simplify i915_gem_release_all_mmaps()
  drm/i915: fix freeze with blank screen booting highmem
  drm/i915: Reorder the semaphore deadlock check, again
