Linus Torvalds ef05db16bb Additional power management updates for 5.7-rc1
- 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).

 "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)"
