[PATCH 1/2] add credits for NUMA placement

From: Rik van Riel
Date: Thu Oct 18 2012 - 17:21:22 EST

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.
