Chris Wilson 561210706c drm/i915/execlists: Remove the ring advancement under preemption ... Load an empty ringbuffer for preemption, ignoring the lite-restore workaround as we know the preempt context is always idle before preemption. Note that after some digging by Michal Winiarski, we found that RING_HEAD is no longer being updated (due to inhibiting context save restore) so this patch is already in effect!
