I doubt there is any hope for recovery if not all processors show up ... things
have to be already very broken for the machine check to be blocked.

I think so.

I'm OK with it going - but as I said before I'd like to see mce_callin printed
(so I can tell if just one cpu showed up, just the cpus from one socket, or
some other significant number).
