-While the ggtt vma are protected by their object lifetime, the list
-continues until it hits a non-ggtt vma, and that vma is not protected
-and may be freed as we inspect it. Hence, we require the obj->vma.lock
-to protect the list as we iterate.
-
-An example of forgetting to hold the obj->vma.lock is

-Now to take the spinlock during the list iteration, we need to break it
-down into two phases. In the first phase under the lock, we cannot sleep
-and so must defer the actual work to a second list, protected by the
-ggtt->mutex.
-
-We also need to hold the spinlock during creation of a new spinlock to
-serialise updates of the tiling on the object.
