Merge branches 'pm-cpufreq' and 'pm-cpuidle'
Merge processor power management changes for v5.20-rc1:
- Make cpufreq_show_cpus() more straightforward (Viresh Kumar).
- Drop unnecessary CPU hotplug locking from store() used by cpufreq
sysfs attributes (Viresh Kumar).
- Make the ACPI cpufreq driver support the boost control interface on
Zhaoxin/Centaur processors (Tony W Wang-oc).
- Print a warning message on attempts to free an active cpufreq policy
which should never happen (Viresh Kumar).
- Fix grammar in the Kconfig help text for the loongson2 cpufreq
driver (Randy Dunlap).
- Use cpumask_var_t for an on-stack CPU mask in the ondemand cpufreq
governor (Zhao Liu).
- Add trace points for guest_halt_poll_ns grow/shrink to the haltpoll
cpuidle driver (Eiichi Tsukata).
- Modify intel_idle to treat C1 and C1E as independent idle states on
Sapphire Rapids (Artem Bityutskiy).
* pm-cpufreq:
cpufreq: ondemand: Use cpumask_var_t for on-stack cpu mask
cpufreq: loongson2: fix Kconfig "its" grammar
cpufreq: Warn users while freeing active policy
cpufreq: ACPI: Add Zhaoxin/Centaur turbo boost control interface support
cpufreq: Drop unnecessary cpus locking from store()
cpufreq: Optimize cpufreq_show_cpus()
* pm-cpuidle:
intel_idle: make SPR C1 and C1E be independent
cpuidle: haltpoll: Add trace points for guest_halt_poll_ns grow/shrink
