This does not address the issue I highlighted Friday: https://lkml.org/lkml/2014/6/13/529 I have an idea on how to fix that issue, but implementing that as part of this series would be silly, since I would have to rip the code back out and completely rewrite it once I started working on placement for systems with complex NUMA topologies. Better to leave that code for then... Patches are against the latest -next and -tip trees.
