    Pull more power management updates from Rafael Wysocki:
     "These are mostly fixes and cleanups on top of the previously merged
      power management material for 5.1-rc1 with one cpupower utility update
      that wasn't pushed earlier due to unfortunate timing.
    
      Specifics:
    
       - Fix registration of new cpuidle governors partially broken during
         the 5.0 development cycle by mistake (Rafael Wysocki).
    
       - Avoid integer overflows in the menu cpuidle governor by making it
         discard the overflowing data points upfront (Rafael Wysocki).
    
       - Fix minor mistake in the recent update of the iowait boost
         computation in the intel_pstate driver (Rafael Wysocki).
    
       - Drop incorrect __init annotation from one function in the pxa2xx
         cpufreq driver (Arnd Bergmann).
    
       - Fix the operating performance points (OPP) framework initialization
         for devices in multiple power domains if only one of them is
         scalable (Rajendra Nayak).
    
       - Fix mistake in dev_pm_opp_set_rate() which causes it to skip
         updating the performance state if the new frequency is the same as
         the old one (Viresh Kumar).
    
       - Rework the cancellation of wakeup source timers to avoid potential
         issues with it and do some cleanups unlocked by that change (Viresh
         Kumar, Rafael Wysocki).
    
       - Clean up the code computing the active/suspended time of devices in
         the PM-runtime framework after recent changes (Ulf Hansson).
    
       - Make the power management infrastructure code use pr_fmt()
         consistently (Joe Perches).
    
       - Clean up the generic power domains (genpd) framework somewhat
         (Aisheng Dong).
    
       - Improve kerneldoc comments for two functions in the cpufreq core
         (Rafael Wysocki).
    
       - Fix typo in a PM QoS file description comment (Aisheng Dong).
    
       - Update the handling of CPU boost frequencies in the cpupower
         utility (Abhishek Goel)"
