Subject[PATCH V5 0/3] cpufreq_cooling: Get effective CPU utilization from scheduler

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 logs of
the patches.

- Don't export enum cpu_util_type and don't pass it as argument to
- Fixed a build issue with !CONFIG_THERMAL_GOV_POWER_ALLOCATOR by moving
{allocate|free}_idle_time() out of CONFIG_THERMAL_GOV_POWER_ALLOCATOR
in patch 3/3.
- Applied Acks from Rafael.

- Broke the first patch into two parts and used effective_cpu_util() in
schedutil (Rafael).

- Removed comment about idle-injection in last patch based on feedback
from Lukasz and added hi Reviewed-by tag.

- 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.

sched/core: Move schedutil_cpu_util() to core.c
sched/core: Rename schedutil_cpu_util() and allow rest of the kernel
to use it
thermal: cpufreq_cooling: Reuse sched_cpu_util() for SMP platforms
