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.
