    ACPI: Notify the _PPC evaluation status to the platform · d81c45e1
    Zhao Yakui authored
    According to the ACPI spec(section 8.4.4.3) OSPM should convey the _PPC
    evaluations status to the platform if there exists the _OST object.
    The _OST contains two arguments:
    	The first is the PERFORMANCE notificatin event.
    	The second is the status of _PPC object.
    OSPM will convey the _PPC evaluation status to the platform.
    Of course when the module parameter of "ignore_ppc" is added, OSPM won't
    evaluate the _PPC object. But it will call the _OST object.
    
    At the same time the _OST object will be evaluated only when the PERFORMANCE
    notification event is received.
