40*7c478bd9Sstevel@tonic-gate 	 * NB: It is not possible to provide a compatible interface
41*7c478bd9Sstevel@tonic-gate 	 * here, if the size of an int is different from the size of a
42*7c478bd9Sstevel@tonic-gate 	 * cell, since we don't know how to promote the arguments.  We
43*7c478bd9Sstevel@tonic-gate 	 * simply promote arguments treating them as unsigned integers;
44*7c478bd9Sstevel@tonic-gate 	 * thus pointers will be properly promoted and negative signed
45*7c478bd9Sstevel@tonic-gate 	 * integer value will not be properly promoted.  This isn't an
46*7c478bd9Sstevel@tonic-gate 	 * issue for LP64 client programs since this code will simply
47*7c478bd9Sstevel@tonic-gate 	 * pass the entire 64-bit arguments through unchanged.
48*7c478bd9Sstevel@tonic-gate 	 *
49*7c478bd9Sstevel@tonic-gate 	 * XXX: This is not fully capable via this interface.  Use
50*7c478bd9Sstevel@tonic-gate 	 * p1275_cif_handler directly for all features.  Specifically,
51*7c478bd9Sstevel@tonic-gate 	 * there's no catch_result and no result cells available via this
52*7c478bd9Sstevel@tonic-gate 	 * interface.  This interface provided for compatibilty with
53*7c478bd9Sstevel@tonic-gate 	 * existing OBP code.  Note that we also assume that the
54*7c478bd9Sstevel@tonic-gate 	 * arguments are not to be sign extended.  Assuming the code
55*7c478bd9Sstevel@tonic-gate 	 * using these arguments is written correctly, this should be OK.
