#     
#     Pull HMM updates from Jason Gunthorpe:
#      "Improvements and bug fixes for the hmm interface in the kernel:
#     
#        - Improve clarity, locking and APIs related to the 'hmm mirror'
#          feature merged last cycle. In linux-next we now see AMDGPU and
#          nouveau to be using this API.
#     
#        - Remove old or transitional hmm APIs. These are hold overs from the
#          past with no users, or APIs that existed only to manage cross tree
#          conflicts. There are still a few more of these cleanups that didn't
#          make the merge window cut off.
#     
#        - Improve some core mm APIs:
#            - export alloc_pages_vma() for driver use
#            - refactor into devm_request_free_mem_region() to manage
#              DEVICE_PRIVATE resource reservations
#            - refactor duplicative driver code into the core dev_pagemap
#              struct
#     
#        - Remove hmm wrappers of improved core mm APIs, instead have drivers
#          use the simplified API directly
#     
#        - Remove DEVICE_PUBLIC
#     
#        - Simplify the kconfig flow for the hmm users and core code"

#       mm: don't select MIGRATE_VMA_HELPER from HMM_MIRROR

#       memremap: move dev_pagemap callbacks into a separate structure
#       memremap: validate the pagemap type passed to devm_memremap_pages
#       mm: factor out a devm_request_free_mem_region helper
#       mm: export alloc_pages_vma
