Keith Busch 8d59f5a2ca acpi/hmat: Register performance attributes
Save the best performance access attributes and register these with the
memory's node if HMAT provides the locality table. While HMAT does make
it possible to know performance for all possible initiator-target
pairings, we export only the local pairings at this time.

If set, this option has the kernel parse and report the
platform's ACPI HMAT (Heterogeneous Memory Attributes Table),
register memory initiators with their targets, and export
performance attributes through the node's sysfs device if
provided.
