Public bug reported:
EDAC_GHES is essential for ARMv8.0 Server systems, as it enables
firmware-first error handling of memory and CPU errors. Due to a lack of
standard RAS architecture (or machine check architecture equivalent) on
ARMv8.0 systems, APEI/GHES is the only mechanism available for reporting
hardware errors (e.g. memory and CPU errors). This enables reporting of
hardware errors, and also helps enable memory fault recovery mechanisms
to extend the life of the system by offlining pages when recoverable
uncorrected errors are encountered. Note that other ARM vendors will be
going in this direction for hardware error handling.
Currently EDAC_MM_EDAC=m is in Ubuntu, but EDAC_GHES requires this to be
=y therefore it is not selected.
