[CELL] oprofile: enable SPU switch notification to detect currently active SPU tasks
From: Maynard Johnson <mpjohn@us.ibm.com>
This patch adds to the capability of spu_switch_event_register so that
the caller is also notified of currently active SPU tasks.
Exports spu_switch_event_register and spu_switch_event_unregister so
that OProfile can get access to the notifications provided.
