5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Lucas Stach <l.stach@xxxxxxxxxxxxxx>
commit 4f8dbadef085ab447a01a8d4806a3f629fea05ed upstream.
The shader L1 cache is a writeback cache for shader loads/stores
and thus must be flushed before any BOs backing the shader buffers
are potentially freed.
