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.
