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