On both it is documented as being must-be-zero. So obey the documentation, and separate the gen2 flush into its own little routine and share with gen3. This means that we can rename the existing render_ring_flush() to reflect the generation from which it first applies and remove the code for handling earlier generations from it. v2: Applies to gen3 as well v3: Make it compile and improve the commit message.
