The NUMA placement code has been rewritten several times, but
the basic ideas took a lot of work to develop. The people who
put in the work deserve credit for it. Thanks Andrea & Peter :)

[ The Documentation/scheduler/numa-problem.txt file should
  probably be rewritten once we figure out the final details of
  what the NUMA code needs to do, and why. ]
