   * tools/ copied this from include/asm-generic/bitops.h, bit by bit as it needed
   * some functions.
   *
   * For the benefit of those who are trying to port Linux to another
   * architecture, here are some C-language equivalents.  You should
   * recode these in the native assembly language, if at all possible.
