    ACPI / ACPICA: Disable GPEs during initialization
    
    GPEs with corresponding _Lxx/_Exx control methods need to be disabled
    during initialization in case they have been enabled by the BIOS, so
    that they don't fire up until they are enabled by acpi_update_gpes().

commit b581a7f9c3abc6c7afacd021747543d32ff17adb
Author: Rafael J. Wysocki <rjw@...k.pl>

    ACPI: Execute _PRW for devices reported as inactive or not present
    
    If a device is reported as inactive or not present by its _STA
    control method, acpi_bus_check_add() skips it without evaluating its
    _PRW method.  This leads to a problem when the device's _PRW method
    points to a GPE, because in that case the GPE may be enabled by
    ACPICA during the subsequent acpi_update_gpes() call which, in
    turn, may cause a GPE storm to appear.
    
    To avoid this issue, make acpi_bus_check_add() evaluate _PRW for
    inactive or not present devices and register the wakeup GPE
    information returned by them, so that acpi_update_gpes() does not
    enable their GPEs unnecessarily.
