Thanks Andrew for the quick review. Other architecture might want to
implement this as well, with tick-less the idle numbers in /proc/stat
are just way off. The implementation of the arch_idle_time is not easy
I'm afraid, the sleep time of each cpu needs to be measured in a way
that it can be read from neighbouring cpus (and it should better be a
precise). Not something I would want to have to implement for x86.
