Linus Torvalds 09583dfed2 Power management updates for 5.19-rc1
- Update the Energy Model support code to allow the Energy Model to be
    artificial, which means that the power values may not be on a uniform
    scale with other devices providing power information, and update the

    artificial Energy Models (Lukasz Luba).
 
  - Make DTPM check the Energy Model type (Lukasz Luba).

    use (Pierre Gondois).

    Kannan, Chanwoo Choi).

  - Make Intel RAPL power capping driver support the RaptorLake and
    AlderLake N processors (Zhang Rui, Sumeet Pawnikar).
 
  - Remove redundant store to value after multiply in the RAPL power
    capping driver (Colin Ian King).
 
  - Add AlderLake processor support to the intel_idle driver (Zhang Rui).
 
  - Fix regression leading to no genpd governor in the PSCI cpuidle
    driver and fix the riscv-sbi cpuidle driver to allow a genpd
    governor to be used (Ulf Hansson).
 
  - Fix cpufreq governor clean up code to avoid using kfree() directly
    to free kobject-based items (Kevin Hao).
 
  - Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe Leroy).
 
  - Make intel_pstate notify frequency invariance code when no_turbo is
    turned on and off (Chen Yu).

    Pandruvada).
 
  - Make cpufreq avoid unnecessary frequency updates due to mismatch
    between hardware and the frequency table (Viresh Kumar).
 
  - Make remove_cpu_dev_symlink() clear the real_cpus mask to simplify
    code (Viresh Kumar).
 
  - Rearrange cpufreq_offline() and cpufreq_remove_dev() to make the
    calling convention for some driver callbacks consistent (Rafael
    Wysocki).
 
  - Avoid accessing half-initialized cpufreq policies from the show()
    and store() sysfs functions (Schspa Shi).
 
  - Rearrange cpufreq_offline() to make the calling convention for some
    driver callbacks consistent (Schspa Shi).
 
  - Update CPPC handling in cpufreq (Pierre Gondois).

Pull power management updates from Rafael Wysocki:
 "These add support for 'artificial' Energy Models in which power
  numbers for different entities may be in different scales, add support
  for some new hardware, fix bugs and clean up code in multiple places.

  Specifics:

   - Update the Energy Model support code to allow the Energy Model to
     be artificial, which means that the power values may not be on a
