    very close to the end of the file:

    alternatives_smp_module_add(NULL, "core kernel",
    __smp_locks, __smp_locks_end,
    _text, _etext);

    The core kernel is just a "special" module (where we keep track of the
    .text section boundaries too), and LOCKs outside the _text -> _etext
    range are never ever patched.
