As mentioned above these 4-letter names from from the ACPI specification. ERST
is perhaps the dumbest name of them all - "Error Record Serialization Table" is
ACPI-speak for platform level non-volatile memory.  This code simply provides
a mechanism for Linux to stash some information in nvram before the system is
reset, and to retrieve it after the reboot.

The naming could be better - but I don't see any overlap with EDAC here.
