Well, *everything* the kernel does is in some way connected to a CPU,
because we always execute the kernel on a CPU, still we have things like
discrete PMUs and abstractions for other pieces of hardware that are not
per CPU.

So the real question is, is there a signifcant class of MCE events that
are not tied to the reporting channel which is per CPU (-ish ...) MCA
banks?

Thanks,

Ingo
