Well, it occurs to me that if you're using jump_label_enable() very early, then it will be using the full arch_jump_label_transform() anyway. While the stop_machine(), locking, etc that the full version does is redundant in a pre-SMP environment, it shouldn't hurt, so perhaps there's no need for an _early variant at all.
