Generic support for non-volatile memory devices including
ACPI-6-NFIT defined resources. On platforms that define an
NFIT, or otherwise can discover NVDIMM resources, a libnvdimm
bus is registered to advertise PMEM (persistent memory)
namespaces (/dev/pmemX) and BLK (sliding mmio window(s))
namespaces (/dev/ndblkX.Y). A PMEM namespace refers to a
memory resource that may span multiple DIMMs and support DAX
(see CONFIG_DAX). A BLK namespace refers to an NVDIMM control
region which exposes an mmio register set for windowed access
mode to non-volatile memory.
