That's a Linux-specific property and that's useless for other operating
systems and not normally allowed. PM noirq is just some Linux thing.

*FIRST* we should check if putting the callbacks to noirq is fine with
other systems too, and I don't see why not. Perhaps we need to even
merge it if we don't get any test results.

If it doesn't work we can think of other options.

Yours,
