  13.  * Make sure the compiler doesn't do anything stupid with the
  14.  * arguments on the stack - they are owned by the *caller*, not
  15.  * the callee. This just fools gcc into not spilling into them,
  16.  * and keeps it from doing tailcall recursion and/or using the
  17.  * stack slots for temporaries, since they are live and "used"
  18.  * all the way to the end of the function.
  19.  *
  20.  * NOTE! On x86-64, all the arguments are in registers, so this
  21.  * only matters on a 32-bit kernel.
