sched: per-cpu mostly_idle threshold
sched_mostly_idle_load and sched_mostly_idle_nr_run knobs help pack
tasks on cpus to some extent. In some cases, it may be desirable to
have different packing limits for different cpus. For example, pack to
a higher limit on high-performance cpus compared to power-efficient
cpus.
This patch removes the global mostly_idle tunables and makes them
per-cpu, thus letting task packing behavior to be controlled in a
fine-grained manner.
