23 * the callee. This just fools gcc into not spilling into them,
24 * and keeps it from doing tailcall recursion and/or using the
25 * stack slots for temporaries, since they are live and "used"
26 * all the way to the end of the function.

28 * NOTE! On x86-64, all the arguments are in registers, so this
29 * only matters on a 32-bit kernel.
