Makes sense.

Whatever we do, I'd like to have this all nicely documented *why* we're
doing the recovery policy we're doing.

So I read GHES_SEV_PANIC as: we should panic and stop any processing
whatsoever ASAP in order to avoid further error propagation. So doing
recovery there might *actually* be a bad idea.

GHES_SEV_NO would map to AER_CORRECTABLE and I think that would mean,
print the error to let the user know but no need to recover because no
harm was done.

I *think*.
