#     
#     Pull hmm updates from Jason Gunthorpe:
#      "Ralph has been working on nouveau's use of hmm_range_fault() and
#       migrate_vma() which resulted in this small series. It adds reporting
#       of the page table order from hmm_range_fault() and some optimization
#       of migrate_vma():
#     
#        - Report the size of the page table mapping out of hmm_range_fault().
#     
#          This makes it easier to establish a large/huge/etc mapping in the
#          device's page table.
#     
#        - Allow devices to ignore the invalidations during migration in cases
#          where the migration is not going to change pages.
#     
#          For instance migrating pages to a device does not require the
#          device to invalidate pages already in the device.
#     
#        - Update nouveau and hmm_tests to use the above"
