The following commit has changed ACPICA table header definitions:
Commit: 88f074f487
Subject: ACPI, CPER: Update cper info
While such definitions are currently maintained in ACPICA. As the
modifications applying to the table definitions affect other OSPMs'
drivers, it is very difficult for ACPICA to initiate a process to
complete the merge. Thus this commit finally only leaves us divergences.
Revert such naming modifications to reduce the source code differecnes
between Linux and ACPICA upstream. No functional changes.
