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. Applied Jason Gunthorpe's suggestions for nouveau_pfns_to_args().
Changes since v1: Rebase to linux-5.6.0-rc4 Address Christoph Hellwig's comments
Ralph Campbell (4): nouveau/hmm: fix vma range check for migration nouveau/hmm: check for SVM initialized before migrating nouveau: remove useless SVM range check nouveau/hmm: map pages after migration
