We want to start using ww locking in intel_context_pin, for this
we need to lock multiple objects, and the single i915_gem_object_lock
is not enough.
Convert to using ww-waiting, and make sure we always pin intel_context_state,
even if we don't have a renderstate object.

Execbuffer submission will perform its own WW locking, and we
cannot rely on the implicit lock there.
This also makes it clear that the GVT code will get a lockdep splat when
multiple batchbuffer shadows need to be performed in the same instance,
fix that up.

Instead of using intel_context_create_request(), use intel_context_pin()
and i915_create_request directly.
Now all those calls are gone outside of selftests. :)

This reverts commit 0f1dd02295f35dcdcbaafcbcbbec0753884ab974.
This conflicts with the ww mutex handling, which needs to drop
the references after gpu submission anyway, because otherwise we
may risk unlocking a BO after first freeing it.

We want to start using ww locking in intel_context_pin, for this
we need to lock multiple objects, and the single i915_gem_object_lock
is not enough.
Convert to using ww-waiting, and make sure we always pin intel_context_state,
even if we don't have a renderstate object.

This function does not use intel_context_create_request, so it has
to use the same locking order as normal code. This is required to
shut up lockdep in selftests.

Those arguments are already set as eb.file and eb.args, so kill off
the extra arguments. This will allow us to move eb_pin_engine() to
after we reserved all BO's.

Execbuffer submission will perform its own WW locking, and we
cannot rely on the implicit lock there.
This also makes it clear that the GVT code will get a lockdep splat when
multiple batchbuffer shadows need to be performed in the same instance,
fix that up.

Instead of using intel_context_create_request(), use intel_context_pin()
and i915_create_request directly.
Now all those calls are gone outside of selftests. :)

Some i915 selftests still use i915_vma_lock() as inner lock, and
intel_context_create_request() intel_timeline->mutex as outer lock.
Fortunately for selftests this is not an issue, they should be fixed
but we can move ahead and cleanify lockdep now.
