3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dave Airlie <[email protected]> commit 16a5e32b83fd946312b9b13590c75d20c95c5202 upstream. My rv515 card is very flaky with msi enabled. Every so often it loses a rearm and never comes back, manually banging the rearm brings it back.
