--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
Yet another false positive. In i915_vma_revoke_mmap, the mapping is the
device-local GTT mapping, which is barred from being used as a source for
userptr -- because of this deadlock.

We could overwrite the lockclass for the device local mapping, I think.
