Actually, we can go even one radical step further and drop
ghes_severity() completely because GHES severity in the ACPI spec 5.0 is
defined almost exactly the same:

"18.3.2.6.1 Generic Error Data

...

Identifies the error severity of the reported error:
0 â Recoverableï
1 â Fatalï
2 â Correctedï
3 â None
Note: This is the error severity of the entire event. Each Generic
Error Data Entry also includes its own Error Severity field."

I don't know which version of the spec dictated

enum {
GHES_SEV_NO = 0x0,
GHES_SEV_CORRECTED = 0x1,
GHES_SEV_RECOVERABLE = 0x2,
GHES_SEV_PANIC = 0x3,
};

though and whether we're going to have to differentiate between the old
and GHES numerical severity levels. Which, if we have to, would be very
nasty...
