Linus Torvalds 40e8e98f51 Power management updates for 6.5-rc1 ...

- Introduce power capping core support for Intel TPMI (Topology Aware
    Register and PM Capsule Interface) and a TPMI interface driver for
    Intel RAPL (Zhang Rui, Dan Carpenter).
 
  - Fix CONFIG_IOSF_MBI dependency in the Intel RAPL power capping
    driver (Zhang Rui).
 
  - Fix invalid initialization for pl4_supported field in the Intel RAPL
    power capping driver (Sumeet Pawnikar).
 
  - Clean up the intel_idle driver, make it work with VM guests that
    cannot use the MWAIT instruction and address the case in which the
    host may enter a deep idle state when the guest is idle (Arjan van
    de Ven).
 
  - Prevent cpufreq drivers that provide the ->adjust_perf() callback
    without a ->fast_switch() one which is used as a fallback from the
    former in some cases (Wyes Karny).
 
  - Fix some issues related to the AMD P-state cpufreq driver (Mario
    Limonciello, Wyes Karny).
 
  - Fix the energy_performance_preference attribute handling in the
    intel_pstate driver in passive mode (Tero Kristo).
 
  - Fix the handling of pm_suspend_target_state when CONFIG_PM is unset
    (Kai-Heng Feng).
 
  - Correct spelling mistake in a comment in the hibernation code (Wang
    Honghui).
 
  - Add arch_resume_nosmt() prototype to avoid a "missing prototypes"
    build warning (Arnd Bergmann).
 
  - Restrict pm_pr_dbg() to system-wide power transitions and use it in
    a few additional places (Mario Limonciello).
 
  - Drop verification of in-params from genpd_add_device() and ensure
    that all of its callers will do it (Ulf Hansson).
 
  - Prevent possible integer overflows from occurring in
    genpd_parse_state() (Nikita Zhandarovich).
 
  - Reorder fieldls in 'struct devfreq_dev_status' to reduce its size
    somewhat (Christophe JAILLET).
 
  - Ensure that the Exynos PPMU driver is already loaded before the
    Exynos Bus driver starts probing so as to avoid a possible freeze
    loading of the kernel modules (Marek Szyprowski).
 
  - Fix variable deferencing before NULL check in the mtk-cci devfreq
    driver (Sukrut Bellary).
