Re: intel_idle

I agree that the SDM doesn't guarantee this MSR exists
based on the presence of PC10.

I'm not opposed to _safe().

but...

Why is this "platform" advertising PC10 (or any MWAIT C-states) to intel_idle
in the first place?

It seems that it should be advertising none, and the intel_idle driver should
not be loading at all, no?
