Ugh.
According to these numbers, the latest sched-numa actually regresses
against mainline on Specjbb.
No way is this even close to ready for merging in the 3.8 timeframe.
I would ask the invilved people to please come up with a set of
initial patches that people agree on, so that we can at least start
merging some of the infrastructure, and see how far we can get on at
least getting *started*. As I mentioned to Andrew and Mel separately,
nobody seems to disagree with the TLB optimization patches. What else?
Is Mel's set of early patches still considered a reasonable starting
point for everybody?
Ingo? Andrea? With the understanding that we're not going to merge the
actual full schednuma/autonuma, what are the initial parts we can
*agree* on?
