 *	To add a new entry:
 *		Add an "MACH_TRAP(routine, arg count)" to the table below.
 *
 *		Add trap definition to mach/syscall_sw.h and
 *		recompile user library.
 *
 * WARNING:	If you add a trap which requires more than 7
 *		parameters, mach/ca/syscall_sw.h and ca/trap.c both need
 *		to be modified for it to work successfully on an
 *		RT.  Similarly, mach/mips/syscall_sw.h and mips/locore.s
 *		need to be modified before it will work on Pmaxen.
 *
 * WARNING:	Don't use numbers 0 through -9.  They (along with
 *		the positive numbers) are reserved for Unix.
