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" * tag 'for-linus-hmm' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: MAINTAINERS: add HMM selftests mm/hmm/test: add selftests for HMM mm/hmm/test: add selftest driver for HMM mm/hmm: remove the customizable pfn format from hmm_range_fault mm/hmm: remove HMM_PFN_SPECIAL drm/amdgpu: remove dead code after hmm_range_fault() mm/hmm: make hmm_range_fault return 0 or -1
