Mostly that not everyone wants to run EDAC drivers.

Plausibly. But it is model specific. Needs to know how h/w banks are shared
between logical CPUs so it can get the time comparisons right when a shared
bank reports BFF overflow on different CPUs. Intel doesn't have any enumeration
for bank sharing, and changes things often.

It's also just for one (not yet released) CPU model today. So, building it into the MCE
code would be overhead for almost everyone.

But I can move it if you think that is a better place for it.
