[RESEND PATCH 0/3] nouveau: fixes for SVM
These are based on 5.8.0-rc2 and intended for Ben Skeggs' nouveau tree.
I believe the changes can be queued for 5.8-rcX after being reviewed.
These were part of a larger series but I'm resending them separately as
suggested by Jason Gunthorpe.

[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.
