/*
 * MV_IOCTL_LEAVING_S0 is a notification when the system is going 
 * to leaving S0. This gives the driver a chance to do some house
 * keeping work before system really going to sleep.
 *
 * The MV_IOCTL_LEAVING_S0 will be translated to APICDB0_ADAPTER/
 * APICDB1_ADAPTER_POWER_STATE_CHANGE and passed down along the
 * module stack. A module shall handle this request if necessary.
 *
 * Upon this request, usually the Cache module shall flush all
 * cached data. And the RAID module shall auto-pause all background
 * activities.
