    Pull more power management updates from Rafael Wysocki:
     "Additional power management updates.
    
      These fix a corner-case suspend-to-idle wakeup issue on systems where
      the ACPI SCI is shared with another wakeup source, add a kernel
      command line option to set pm_debug_messages via the kernel command
      line, add a document desctibing system-wide suspend and resume code
      flows, modify cpufreq Kconfig to choose schedutil as the preferred
      governor by default in a couple of cases and do some assorted
      cleanups.
    
      Specifics:
    
       - Fix corner-case suspend-to-idle wakeup issue on systems where the
         ACPI SCI is shared with another wakeup source (Hans de Goede).
    
       - Add document describing system-wide suspend and resume code flows
         to the admin guide (Rafael Wysocki).
    
       - Add kernel command line option to set pm_debug_messages (Chen Yu).
    
       - Choose schedutil as the preferred scaling governor by default on
         ARM big.LITTLE systems and on x86 systems using the intel_pstate
         driver in the passive mode (Linus Walleij, Rafael Wysocki).
    
       - Drop racy and redundant checks from the PM core's device_prepare()
         routine (Rafael Wysocki).
    
       - Make resume from hibernation take the hibernation_restore() return
         value into account (Dexuan Cui)"
