	  Support raw access to differentiated (persistence, bandwidth,
	  latency...) memory via an mmap(2) capable character
	  device.  Platform firmware or a device driver may identify a
	  platform memory resource that is differentiated from the
	  baseline memory pool.  Mappings of a /dev/daxX.Y device impose
	  restrictions that make the mapping behavior deterministic.

	help
	  EFI 2.8 platforms, and others, may advertise 'specific purpose'
	  memory. For example, a high bandwidth memory pool. The
	  indication from platform firmware is meant to reserve the
	  memory from typical usage by default. This driver creates
	  device-dax instances for these memory ranges, and that also
	  enables the possibility to assign them to the DEV_DAX_KMEM
	  driver to override the reservation and add them to kernel
	  "System RAM" pool.

	  Say M if unsure.

	  Older versions of the libdaxctl library expect to find all

	  your distribution is older than v58 say M, otherwise say N.
