Linus Torvalds 6ef746769e More power management updates for 4.20-rc1
- Fix build regression in the intel_pstate driver that doesn't
    build without CONFIG_ACPI after recent changes (Dominik Brodowski).
 
  - One of the heuristics in the menu cpuidle governor is based on a
    function returning 0 most of the time, so drop it and clean up
    the scheduler code related to it (Daniel Lezcano).
 
  - Prevent the arm_big_little cpufreq driver from being used on ARM64
    which is not suitable for it and drop the arm_big_little_dt driver
    that is not used any more (Sudeep Holla).
 
  - Prevent the hung task watchdog from triggering during resume from
    system-wide sleep states by disabling it before freezing tasks and
    enabling it again after they have been thawed (Vitaly Kuznetsov).

Pull more power management updates from Rafael Wysocki:
 "These remove a questionable heuristic from the menu cpuidle governor,
  fix a recent build regression in the intel_pstate driver, clean up ARM
  big-Little support in cpufreq and fix up hung task watchdog's
  interaction with system-wide power management transitions.

  Specifics:

   - Fix build regression in the intel_pstate driver that doesn't build
     without CONFIG_ACPI after recent changes (Dominik Brodowski).

   - One of the heuristics in the menu cpuidle governor is based on a
     function returning 0 most of the time, so drop it and clean up the
     scheduler code related to it (Daniel Lezcano).

   - Prevent the arm_big_little cpufreq driver from being used on ARM64
     which is not suitable for it and drop the arm_big_little_dt driver
     that is not used any more (Sudeep Holla).

   - Prevent the hung task watchdog from triggering during resume from
     system-wide sleep states by disabling it before freezing tasks and
     enabling it again after they have been thawed (Vitaly Kuznetsov)"
