Is this going to be duplicate for each architecture enabling this?

This will allow the kernel to keep track of energy required for different capacity levels for a given CPU. That way, the scheduler can make more informed decisions as to where a newly woken task should be placed. Heterogenous platform will benefit the most from this option. Enabling this will add a significant overhead for a task-switch. If unsure, say N here.
