Hi all,

I've stitched together the following set of workarounds from internal sources in
the vain hope that they fix our VT-d troubles. Unfortunately that's not the
case. I also haven't seen any bug where these could apply to.

Anyway I think it's better to implement them, so please review.

Yours, Daniel

PS: With this set we now implement all but 2 workarounds on from this internal
list (when filtering out everything that only applies for pre-production
silicon). These 2 concern gl features I don't have much clue about, I've instead
forwarded the relevant entries to Ken and Paul from our gl team.

Daniel Vetter (7):
  drm/i915: implement ColorBlt w/a
  drm/i915: implement a media hang w/a
  drm/i915: set w/a bit for snb pagefaults
  drm/i915: properly set ppgtt cacheability on snb
  drm/i915: implement w/a for incorrect guarband clipping
  drm/i915: implement async flush w/a
  drm/i915: set stc evict disable lra evict w/a
