I think you should also remove the "manual" declarations from the .c files that call the function, in this case fork_init() in init/main.c; otherwise there's no guarantee that those translation units actually include the header that contain the proper declaration. arch_release_thread_stack can probably just be removed completely after the recent arch cleanup, since bb9d81264 (arch: remove tile port) no arch seems to implement it.
