Merge tag 'drm-intel-fixes-2013-09-06' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

- Early stolen mem reservation from Jesse in x86 boot code. Acked by Ingo
  and hpa.  This was ready much earlier but somehow I've thought it'd go
  in through x86 trees, hence why this is late. Avoids the pci resource
  code to plant mmiobars in the middle of stolen mem and other ugliness.
- vgaarb improvements from Alex Williamson plus the fix from Ville for the
  vgacon->fbcon smooth transition "feature".
- Render pageflips on ivb/hsw to avoid stalls due to the ring switching
  when only flipping on the blitter (Chris).
- Deadlock fixes around our flush_workqueue which crept back in - lockdep
  isn't clever enough :(
- Shrinker recursion fix from Chris - this is the thing that blew the vma
  patches from Ben I've taken out of 3.12.
- Fixup for the relocation refactoring. Also an igt testcase to make sure
  we don't break this again.
- Pile of smaller fixups all over, shortlog has full details.
