Yeah.. that's true.
Any improvements here you can suggest?
We could uhm... /me tries thinking ... reuse some of the NOHZ magic? Would that be sufficient, not waking a NOHZ cpu, or do you really want not waking any idle cpu?
Depending on the trade-off we could have the NOHZ stuff track a non-NOHZ-idle cpu and avoid having to compute one every time we need it.
