ACPI: Notify the _PPC evaluation status to the platform
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.
