  1. [PATCH] x86: MPSC should use P6 NOPs

    I've now noticed that the machine I call MPENTIUM4 for 32-bit kernels
    is called MPSC for 64-bit kernels, and in that case it still doesn't
    get the P6 NOPs it ought to. hpa explains that MK8 should still be
    excluded, so it's just a matter of including MPSC along with MPENTIUM4.
