- * This macro flushes all outstanding PIOs performed by this cpu to the 
- * intended destination SHUB.  This in essence ensures that all PIO's
- * issues by this cpu has landed at it's destination.
- *
- * This macro expects the caller:
- *	1.  The thread is locked.
- *	2.  All prior PIO operations has been fenced with __ia64_mf_a().
- *
- * The expectation is that get_slice() will return either 0 or 2.
- * When we have multi-core cpu's, the expectation is get_slice() will 
- * return either 0,1 or 2,3.
