hmm_range_fault related fixes and legacy API removal v2
Hi Jérôme, Ben and Jason,
below is a series against the hmm tree which fixes up the mmap_sem
locking in nouveau and while at it also removes leftover legacy HMM APIs
only used by nouveau.
Changes since v1:
- don't return the valid state from hmm_range_unregister
- additional nouveau cleanups

hmm_range_fault related fixes and legacy API removal v3
Hi Jérôme, Ben and Jason,
below is a series against the hmm tree which fixes up the mmap_sem
locking in nouveau and while at it also removes leftover legacy HMM APIs
only used by nouveau.
The first 4 patches are a bug fix for nouveau, which I suspect should
go into this merge window even if the code is marked as staging, just
to avoid people copying the breakage.
Changes since v2:
- new patch
