  12 * Note: Yes, part of the following code is located into the .data section.
  13 *       This is to allow jumpaddr to be accessed with a relative load
  14 *       while we can't rely on any MMU translation.  We could have put
  15 *       sleep_save_sp in the .text section as well, but some setups might
  16 *       insist on it to be truly read-only.
