Subject: [PATCH] drm/i915: Invalidate media caches on gen7
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

In the gen7 pipe control there is an extra bit to flush the media
caches, so let's set it during cache invalidation flushes.

v2: Rename to MEDIA_STATE_CLEAR to be more inline with spec.
