Linus Torvalds 85671b807f More power management updates for 7.3-rc1
- Fix a kernel panic during PMU unbind in the intel_rapl power capping
    driver and sign-extend the PMU delta on counter wraparound in it to
    avoid misreporting energy (Sumeet Pawnikar and Yifan Li)
 
  - Unblock runtime PM when device prepare fails that was not done by
    mistake (Shibo Zhu)
 
  - Fix possible rate limit overflow on 32-bit systems in the schedutil
    cpufreq governor (Hui Su)
 
  - Consolidate HWP P-states initialization in the intel_pstate cpufreq
    driver and make that driver avoid using the DESIRED_PERF HWP hint
    when the Dynamic Efficiency Control (DEC) is enabled in the processor
    to avoid inconsistent behavior (Rafael Wysocki)

 "These fix two issues in the intel_rapl power capping driver, fix a
  potential issue in the schedutil cpufreq governor on 32-bit systems,
  fix a runtime PM issue related to failing system suspend, and update
  the intel_pstate cpufreq driver:
