kexec: dont initialise regions in reserve_memory()

462 * is no problem, but for the stack. This is handled by not letting
463 * main() use the stack at all after fork(). Thus, no function
464 * calls - which means inline code for fork too, as otherwise we
465 * would use the stack upon exit from 'fork()'.
466 *
467 * Actually only pause and fork are needed inline, so that there
468 * won't be any messing with the stack from main(), but we define
469 * some others too.
