  17           latency...) memory via an mmap(2) capable character
  18           device.  Platform firmware or a device driver may identify a
  19           platform memory resource that is differentiated from the
  20           baseline memory pool.  Mappings of a /dev/daxX.Y device impose
  21           restrictions that make the mapping behavior deterministic.
