Hi Dave, Daniel, please pull those etnaviv changes as fixes for the 5.15 release series. Fixes a very annoying issue where the driver view of the MMU state gets out of sync with the actual hardware state across a runtime PM cycle, so we end up restarting the GPU with the wrong (potentially already freed) MMU context. Hilarity ensues.
