Merge tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull hmm updates from Jason Gunthorpe:
"This series adds a selftest for hmm_range_fault() and several of the
DEVICE_PRIVATE migration related actions, and another simplification
for hmm_range_fault()'s API.
- Simplify hmm_range_fault() with a simpler return code, no
HMM_PFN_SPECIAL, and no customizable output PFN format
- Add a selftest for hmm_range_fault() and DEVICE_PRIVATE related
functionality"
