Linus Torvalds ccc5e98177 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

    governor (Rafael Wysocki).

    cases (Liao Chang).
 
  - Fix two issues in the amd-pstate-ut cpufreq driver (Swapnil Sapkal).

    cpufreq_verify_within_limits() (Liao Chang).
 
  - Set stale CPU frequency to minimum in intel_pstate (Doug Smythies).
 
  - Migrate cpufreq drivers for various platforms to use void remove
    callback (Yangtao Li).
 
  - Add online/offline/exit hooks for Tegra driver (Sumit Gupta).
 
  - Explicitly include correct DT includes in cpufreq (Rob Herring).
 
  - Frequency domain updates for qcom-hw driver (Neil Armstrong).
 
  - Modify AMD pstate driver return the highest_perf value (Meng Li).

    Del Regno and Konrad Dybcio).
 
  - brcmstb-avs-cpufreq: Fix -Warray-bounds bug (Gustavo A. R. Silva).
 
  - Add device PM helpers to allow a device to remain powered-on during
    system-wide transitions (Ulf Hansson).
 
  - Rework hibernation memory snapshotting to avoid storing pages filled
    with zeros in hibernation image files (Brian Geffon).
 
  - Add check to make sure that CPU latency QoS constraints do not use
    negative values (Clive Lin).
 
  - Optimize rp->domains memory allocation in the Intel RAPL power
    capping driver (xiongxin).
 
  - Remove recursion while parsing zones in the arm_scmi power capping
    driver (Cristian Marussi).
