Maarten Lankhorst (68):
drm/i915: Do not share hwsp across contexts any more, v7.
drm/i915: Pin timeline map after first timeline pin, v3.
drm/i915: Move cmd parser
Make creation separate from pinning, in order to take the lock only

Currently we have a lot of places where we hold the gem object lock,
but haven't yet been converted to the ww dance. Complain loudly about
those places.
i915_vma_pin shouldn't have the obj lock held, so we can do a ww dance,
while i915_vma_pin_ww should.

Take the ww lock around engine_unpark. Because of the
many many places where rpm is used, I chose the safest option
and used a trylock to opportunistically take this lock for
__engine_unpark.
