Interaction with irqbalancing? What about interaction with various forms of power save or suspend/resume? (Hmm side note - how do I detect that I have ARMv7MP as opposed to plain v7 - i.e. that I can do a PLDW - if anything is doing it by detecting multiple CPUs it might get confused by hotplug sometimes only showing one - I suspect that's the wrong way).
