3.16.7-ckt4 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Chris Wilson <[email protected]> commit 148b83d0815a3778c8949e6a97cb798cbaa0efb3 upstream. 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.
