Given how minimalistic balancenuma is, and how there does not seem
to be anything significant in the way of performance regressions
with balancenuma, I have no objections to Linus merging all of
balancenuma for 3.8.

That could significantly reduce the amount of NUMA code we need
to "fight over" for the 3.9 kernel :)
