 *	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/{machine}/syscall_sw.h and {machine}/trap.c
 *		and/or {machine}/locore.s may need to be modified for it
 *		to work successfully.
 *
 * WARNING:	Don't use numbers 0 through -9.  They (along with
 *		the positive numbers) are reserved for Unix.
 *
 * WARNING:	The 'arg_count' parameter in the list below is poorly named.
 *		It doesn't refer to the number of arguments the trap takes -
 *		it actually refers to the number of 32-bit words that need
 *		to be copied in from userspace.  The munging of words to trap
 *		arguments is done in mach_call_munger().
