   * Syscall argument mungers.
   *
   * The data to be munged has been explicitly copied in to the argument
   * area, and will be munged in place in the uu_arg[] array. These
   * mungers are for 32-bit app's syscalls, since 64-bit args are copied
   * from the save area to the uu_args in the order the
   * syscall ABI calls for.
   *
   * The issue is that the incoming args are 32-bit, but we must expand
   * them in place into 64-bit args, as if they were from a 64-bit process.
   *
   * There are several functions in this file with the following prototype
   *
   *	void	munge_XXXX(void *uu_args);
   *
   * The name of the function encodes the number and type of the parameters,
   * as follows:
   *
   *	w = a 32-bit value such as an int or a 32-bit ptr, that does not
   *	    require sign extension.  These are handled by zeroing a word
   *          of output, and copying a word from input to output.
   *
   *	s = a 32-bit value such as a long, which must be sign-extended to
   *	    a 64-bit long-long in the uu_args.  These are handled by
   *	    loading a word of input and sign extending it to a double,
   *          and storing two words of output.
   *
   *	l = a 64-bit long-long.  These are handled by copying two words
   *          of input to the output.
   *
   * For example, "munge_wls" takes a word, a long-long, and a word.  This
   * takes four words in the uu_arg[] area: the first word is in one, the
   * long-long takes two, and the final word is in the fourth.  We store six
   * words: the low word is left in place, followed by a 0, followed by the
   * two words of the long-long, followed by the low word and the sign extended
   * high word of the preceeding low word.
   *
   * Because this is an in-place modification, we actually start at the end
   * of uu_arg[] and work our way back to the beginning of the array.
