      PM: Introduce PM_EVENT_HIBERNATE callback state · 3a2d5b70
      Rafael J. Wysocki authored
      During the last step of hibernation in the "platform" mode (with the
      help of ACPI) we use the suspend code, including the devices'
      ->suspend() methods, to prepare the system for entering the ACPI S4
      system sleep state.
      
      But at least for some devices the operations performed by the
      ->suspend() callback in that case must be different from its operations
      during regular suspend.
      
      For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
      pass it to the device drivers' ->suspend() methods during the last phase
      of hibernation, so that they can distinguish this case and handle it as
      appropriate.  Modify the drivers that handle PM_EVENT_SUSPEND in a
      special way and need to handle PM_EVENT_HIBERNATE in the same way.
      
      These changes are necessary to fix a hibernation regression related
      to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).
