- * ia64_sn_probe_io_slot
- *	This function will probe a physical address to determine if
- *	the address can be read. If reading the address causes a BUS
- *	error, an error is returned. If the probe succeeds, the contents 
- *	of the memory location is returned.
- *
- *   Calling sequence:
- *		ia64_probe_io_slot(paddr, size, data_ptr)
- *
- *   Input:
- *	paddr		Physical address to probe
- *	size		Number bytes to read (1,2,4,8)
- *	data_ptr	Address to store value read by probe
- *		          (-1 returned if probe fails)
- *
- *   Output:
- *	Status
- *		 0 - probe successful
- *		 1 - probe failed (generated MCA)
- *		 2 - Bad arg
- *		<0 - PAL error
