#1661576 — [PATCH v2 0/2] NVDIMM memory error notification support

ACPI 6.2 defines a new ACPI notification value to NVDIMM Root Device.
This allows BIOS to inform the OS that new uncorrectable memory error
is detected during run-time.

This patch-set adds support of this notification, which starts ARS and
updates badblocks information to prevent the OS from consuming the new
error.

v2:
 - Set flags Bit[1] for Start ARS. (Dan Williams)
