For completeness, I should add that the upstream fix introduces another bug which may cause some corruption. This one is fixed in this commit:

   drm/i915: Don't skip ring flushes if only invalidating

   Commit 15056d2 tried to optimize away a flush if there were no
   outstanding writes on a ring (in order to prevent a too-early-flush
   during ring init). However, this has the unfortunate side-effect of
   eliminating the texture cache invalidation, and so causing rendering
   artefacts.
