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.
