Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel

Just a few small things:
- 2x workaround bits from Chris to fix up the new scanline waits enabled
  in 3.8 on snb. People who've been struck by this on dual-screen also
  need to upgrade the ddx.
- Dump the kernel version into i915_error_state, we've had a few mixups
  there recently.
- Disable gfx DMAR on gen4 devices, acked by David Woodhouse.
