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