Caller
NameDescribe
machine_check_pollPoll for corrected events or events that happened before reset.* Those are just logged through /dev/mcelog.* This is executed in standard interrupt context.* Note: spec recommends to panic for fatal unsignalled* errors here
mce_no_way_outDo a quick check if any of the events requires a panic.* This decides if we keep the events around or clear them.
