For this series in general I'd personally be inclined to include it in
the merge of [1] as the large GPUVA change isn't going to apply after
this series as GPUVA is really invasive / rebase is non-trival. Also
based on a coversation with dakr [2] [3], we probably want to move some
of our locking helpers to GPUVA + do not build DRM EXEC as a module.
