41
+	  EFI 2.8 platforms, and others, may advertise 'specific purpose'
42
+	  memory. For example, a high bandwidth memory pool. The
43
+	  indication from platform firmware is meant to reserve the
44
+	  memory from typical usage by default. This driver creates
45
+	  device-dax instances for these memory ranges, and that also
46
+	  enables the possibility to assign them to the DEV_DAX_KMEM
47
+	  driver to override the reservation and add them to kernel
48
+	  "System RAM" pool.
