Not quite true for migration threads; they're kicked off smp_init(), called strictly after smp_prepare_cpus(), so all's well with them. The idle threads shouldn't enter schedule() either, since start_secondary() spins until smp_init() sets the smp_commenced_mask bits in cpu_up().
So the important parts of all that were unfortunately all wrong. I'll look again.
