In the long term I wonder if it's worth putting PELT under its own
separate feature or just removing #ifdef CONFIG_SMP.

Aside from task migration CPU frequency updates there's also task
creation and deletion which would apply on UP. The tunable
infrastructure being created for scheduler-guided frequency may be of
interest on UP also.
