    [PATCH] sched: tidy up left over smpnice code
    1. The only place that RTPRIO_TO_LOAD_WEIGHT() is used is in the call to
    move_tasks() in the function active_load_balance() and its purpose here
    is just to make sure that the load to be moved is big enough to ensure
    that exactly one task is moved (if there's one available).  This can be
    accomplished by using ULONG_MAX instead and this allows
    RTPRIO_TO_LOAD_WEIGHT() to be deleted.
    2. This, in turn, allows PRIO_TO_LOAD_WEIGHT() to be deleted.
    3. This allows load_weight() to be deleted which allows
    TIME_SLICE_NICE_ZERO to be deleted along with the comment above it.
