The current handling of EPOW_SHUTDOWN_ON_UPS event does not shutdown the system after logging the message. All the events of EPOW_SYSTEM_SHUTDOWN action code (EPOW_SHUTDOWN_ON_UPS is a part of it) must initiate system shutdown as per the SPAPR spec. If the LPAR does not shutdown after receiving this rtas based event, it will expose itself to a forced abrupt shutdown initiated by the platform firmware. This patch fixes the situation.
