Pavel, considering that the processor is in a quiescent state when it's in
the idle thread, can't we simply restart them all when we do the final
sleep? So on the resume, we steer the APs straight into the offline cpu
spin and manually bring them up again when the BSP has resumed? I reckon
we don't have to save any state at all. I probably don't have the full
picture yet so feel free to set me straight.

Thanks,
Zwane
