  Log:
  Restructure the wake GPE API.  Now there are three functions:
  
  acpi_wake_init:
      Evaluate _PRW and set the GPE type
  acpi_wake_set_enable:
      Enable or disable a device's GPE.
  acpi_wake_sleep_prep:
      Perform any last-minute changes to the device to prepare it for
      entering the given sleep state.
  
  Also, walk the entire namespace when transitioning to a sleep state,
  disabling any GPEs which aren't appropriate for the given state.  Transition
  acpi_lid and acpi_button to the new API.
  
  This clears the way for non-ACPI-aware devices to wake the system (i.e.
  modems) and fixes a problem where systems power up after shutdown when a
  GPE is triggered.
