Merge branches 'pm-cpuidle' and 'pm-cpufreq'
Merge CPU power management updates for 6.6-rc1:
- Rework the menu and teo cpuidle governors to avoid calling
tick_nohz_get_sleep_length(), which is likely to become quite
expensive going forward, too often and improve making decisions
regarding whether or not to stop the scheduler tick in the teo
governor (Rafael Wysocki).
- Improve the performance of cpufreq_stats_create_table() in some
cases (Liao Chang).
- Fix two issues in the amd-pstate-ut cpufreq driver (Swapnil Sapkal).
- Use clamp() helper macro to improve the code readability in
cpufreq_verify_within_limits() (Liao Chang).
- Set stale CPU frequency to minimum in intel_pstate (Doug Smythies).
* pm-cpuidle:
cpuidle: teo: Avoid unnecessary variable assignments
cpuidle: menu: Skip tick_nohz_get_sleep_length() call in some cases
cpuidle: teo: Gather statistics regarding whether or not to stop the tick
cpuidle: teo: Skip tick_nohz_get_sleep_length() call in some cases
cpuidle: teo: Do not call tick_nohz_get_sleep_length() upfront
cpuidle: teo: Drop utilized from struct teo_cpu
cpuidle: teo: Avoid stopping the tick unnecessarily when bailing out
cpuidle: teo: Update idle duration estimate when choosing shallower state
* pm-cpufreq:
cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver
cpufreq: amd-pstate-ut: Remove module parameter access
cpufreq: Use clamp() helper macro to improve the code readability
cpufreq: intel_pstate: set stale CPU frequency to minimum
cpufreq: stats: Improve the performance of cpufreq_stats_create_table()
