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.
