    Subject[PATCH 5/8] ACPI, APEI, CPER: Add UEFI 2.4 support for memory error
    Date
    In latest UEFI spec(by now it is 2.4) memory error definition
    for CPER (UEFI 2.4 Appendix N Common Platform Error Record)
    adds some new fields. These fields help people to locate
    memory error on actual DIMM location.
