I put these as separate commits so it is possible for you to take first 
2 patches
if taking the 3rd and 4th patch would cause merge conflicts. My upcoming 
changes
to `dma::Coherent` would also further update the Nova-side callers (I 
guess if you're
also taking these from driver-core tree then it's not an issue).

If you think it's fine to take them via the driver-core tree without 
causing
trouble for drm-rust tree then I can squash them in next version.

Best,
Gary
