Decoupling misfit from overutilized better helps handling misfit due to uclamp_min only being misfit without triggering overutilized state, which is bad from energy point of view as it prematurely disables energy aware scheduling.
The series also makes the search for a better CPU under bad thermal condition more comprehensive, which is useful improvement when the system is under bad thermal condition.
Backports to 5.10.y and 5.15.y is hard as find_energy_efficient_cpu() is different. But it applies cleanly on 6.1.y
Compile tested against various randconfigs for different archs.
Boot tested on android14-6.1 GKI kernel.
Based on v6.1.46
