Looking at the patch, it builds tables that can refer to .init.text but then it excludes table entries that do not fall between _text and _etext. Which makes the reference from .smp_locks to .init.text a false positive. Gerd, is that the way that smp_alternatives is meant to work? If so, I will update reference_*.pl.
+ alternatives_smp_module_add(NULL, "core kernel", + __smp_locks, __smp_locks_end, + _text, _etext);
