  MAINTAINERS: add HMM selftests (2020-05-19 16:48:31 -0300)

----------------------------------------------------------------
hmm related patches for 5.8

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

----------------------------------------------------------------
Jason Gunthorpe (4):
      mm/hmm: make hmm_range_fault return 0 or -1
      drm/amdgpu: remove dead code after hmm_range_fault()
      mm/hmm: remove HMM_PFN_SPECIAL
      mm/hmm: remove the customizable pfn format from hmm_range_fault

Ralph Campbell (3):
      mm/hmm/test: add selftest driver for HMM
      mm/hmm/test: add selftests for HMM
