<pre>commit 09c5ab384f6fb30f834a5777888b4486dd7f015d (HEAD -> drm-intel-next-queued,
drm-intel/for-linux-next, drm-intel/drm-intel-next-queued)

drm/i915: Keep rings pinned while the context is active
Remember to keep the rings pinned as well as the context image until the
GPU is no longer active.
v2: Introduce a ring->pin_count primarily to hide the
mock_ring that doesn't fit into the normal GGTT vma picture.
v3: Order is important in teardown, ringbuffer submission needs to drop
the pin count on the engine->kernel_context before it can gleefully free
its ring.
