"conventions in a subsystem" my ass. That's brainless copy-pasting.
It was added by
f6edea77c8c8 ("ACPI, APEI, CPER: Cleanup CPER memory error output format")
and then replicated everywhere.
It is simply a dumb way of writing:
snprintf(newpfx, sizeof(newpfx), "%s ", pfx);

Yes, at least for the most prominent ones.

If we can't decode it, *then* you dump it:
"Unrecognized type: 0x%llx ..."

1. No one stares at the raw value if the bits are decoded
2. MCA_STATUS is one register - this error record is huge.

Fair enough. Only if it makes sense.
