Hi JÃrÃme, 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

Ralph, since most of this is nouveau could you contribute a
Tested-by? Thanks

Jason


I can test things fairly easily but with all the different patches,
conflicts, and personal git trees, can you specify the git tree
and branch with everything applied that you want me to test?
