69 * To add a new entry:

A		 70 * Add an "MACH_TRAP(routine, arg_count, num_32_bit_words, munge_routine)" to the table below.
71 * where,
72 * - routine: The trap handling routine in the kernel
73 * - arg_count: The number of arguments for the mach trap (independant of arch/arg size).
74 * This value also defines the number of 64-bit words copied in for a U64 process.
75 * - num_32_bit_words: The number of 32-bit words to be copied in for a U32 process.
76 * - munge_routine: The argument munging routine to align input args correctly.
1c79356b 77 *
39236c6e 78 * Also, add trap definition to mach/syscall_sw.h and
1c79356b
