Well, what about intel_idle_freeze()?  Or do we not care?

I argued against it; when you're suspended the NMI watchdog is stopped
too.

Is it also stopped for suspend-to-idle?  I'm not sure about that.

Where do I need to look to find out?

Hmm I have memories of writing a patch to that effect when we were
starting with that suspend-to-idle stuff, because people didn't like
being woken up all the time.

But now that I look I cannot find it either..
