This is the only reason which justifies EDAC's existence. Naveen, can
your BIOS directly report the silkscreen label of the DIMM in error?
Generally, can any BIOS do that?

More specifically, what are those gdata_fru_id and gdata_fru_text
things?

Because if it can, then having the memory error tracepoint come direct
from APEI should be enough. The ghes_edac functionality could be then
fallback for BIOSes which cannot report the silkscreen label and in such
case I can imagine keeping both tracepoints, but disabling one of the
two...
