* ps3_sys_manager - PS3 system manager driver.
*
* The system manager provides an asyncronous system event notification

*
* The actual system manager is implemented as an application running in the
* system policy module in lpar_1. Guests communicate with the system manager
* through port 2 of the vuart using a simple packet message protocol.
* Messages are comprised of a fixed field header followed by a message
* specific payload.
