There are some newer error signatures in Family 15h models 30h-3fh.
Code has been added in the patch to support these new signatures.

Patch has been tested on Fam15h using mce_amd_inj facility and
has been verified to work correctly.

Since "parity error" is already in the printk below, I'm guessing this
string should be "Retire status queue" only?

Okay, that should convey the message too...

No need to resend the patch, btw - I'll fix it up when applying.

Thanks!
