    Peter, Ingo,

    do you have any comments on the performance measurements
    by Mel?

    Any ideas on how to fix sched/numa or numa/core?

    At this point, I suspect the easiest way forward might be
    to merge the basic infrastructure from Mel's combined
    tree (in -mm? in -tip?), so we can experiment with different
    NUMA placement policies on top.

    That way we can do apples to apples comparison of the
    policies, and figure out what works best, and why.
