The function now reads:

int ftrace_arch_code_modify_post_process(void)
    __releases(&text_mutex)
{
	/*
	 * ftrace_module_enable()
	 *   ftrace_arch_code_modify_prepare()
	 *   do_for_each_ftrace_rec()
	 *     __ftrace_replace_code()
	 *       ftrace_make_{call,nop}()
	 *         ftrace_modify_code_direct()
	 *           text_poke_queue()
	 *   ftrace_arch_code_modify_post_process()
	 *     text_poke_finish()
	 */
	text_poke_finish();
	ftrace_poke_late = 0;
	mutex_unlock(&text_mutex);
	return 0;
}

Patch is otherwise unchanged.
