[PATCH v3 0/4] nouveau/hmm: map pages after migration
Originally patch 4 was targeted for Jason's rdma tree since other HMM
related changes were queued there. Now that those have been merged,
these patches just contain changes to nouveau so they could go through
any tree. I guess Ben Skeggs' tree would be appropriate.
Changes since v2:
Added patches 1-3 to fix some minor issues.
Eliminated nouveau_find_svmm() since it is easily found.

When acting on device private mappings a driver needs to know if the

mapping. This series adds an owner field and converts the migrate_vma
code over to check it. I looked into doing the same for
hmm_range_fault, but as far as I can tell that code has never been
wired up to actually work for device private memory, so instead of
