Well about a week ago Bob send me a partial implementation of this and
said he needs it for i915. What exactly i915 needs here I'm not sure
about either.
I have this cleanup in the pipeline because amdgpu wants to improve his
page table handling with this and independent of those driver use case
patches #10 and #11 drop allocating dummy resources for two use cases in
TTM.
