[PATCH] corruption checker: print the DMI board name on corruption

[Arjan van de Ven]

when the memory corruptor checker hits (as it has done now based on
kerneloops.org data), it would be extremely useful to know the DMI board
name so we can add a blacklist for such a machine... without having to ask
the user for lots of extra info.
