Uhm, by opening the MCE event on a particular cpu? Remember that
sys_perf_event_open() has a cpu target.

The thing is, CPUs are assumed symmetric, thus also all MCE events are
symmetric, one CPU cannot generate other MCE than another. So the only
thing that differs is where you want to listen for them.
