CPER madness goes like this:
	0 - Recoverable
	1 - Fatal
	2 - Corrected
	3 - None

As you can see, the numbering was created by crackmonkeys. GHES_* is an
internal enum that goes up in order of severity, as you'd expect.

If you're confused, you're not alone. I've seen several commit messages
that get this terminology wrong.
