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
