Subject[PATCH V3 0/2] cpufreq_cooling: Get effective CPU utilization from scheduler
Date
Hi,

This patchset makes the cpufreq_cooling driver reuse the CPU utilization
metric provided by the scheduler instead of depending on idle and busy
times of a CPU, which aren't that accurate to measure the busyness of a
CPU for the next cycle. More details can be seen in the commit log of
patch 2/2.

V2->V3:
- Put the scheduler helpers within ifdef CONFIG_SMP.
- Keep both SMP and !SMP implementations in the cpufreq_cooling driver.
- Improved commit log with testing related information.
