    Has anyone made any headway with getting polling(4) to work with a SMP
    kernel? Last May this was discussed on here briefly with me, Luigi and
    Don Bowman, which seemed to indicate that the majority of what needed
    to be fixed to make this work would be some kind of locking in
    idle_loop to make sure only one CPU gets into the polling code at once.

    I've got a case where enabling SMP gives me a 20-30% performance boost,
    or if I turn polling on I get another 10-15% boost. I'd love to see
    what the two together could do.
