Chris Wilson 1f7b847d72 drm/i915: Disable engine->irq_tasklet around resets ... When we restart the engines, and we have active requests, a request on the first engine may complete and queue a request to the second engine before we try to restart the second engine. That queueing of the request may race with the engine to restart, and so may corrupt the current state. Disabling the engine->irq_tasklet prevents the two paths from writing into ELSP simultaneously (and modifyin the execlists_port[] at the same time).
