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()
