Something in current -bk breaks the NUMA scheduler.
Kernbench: (make -j N vmlinux, where N = 16 x num_cpus)
Elapsed System User CPU
2.5.64-align 46.29 129.38 567.02 1504.75
2.5.64-bk 153.04 49.05 558.30 395.00
Looks like it's not node-balancing at all and just using one node.
However, I spent a few minutes looking, and can't see anything obvious
that would have caused it.
Will look at it some more tommorow when I wake up, but if any of you
can see what's broken of the top of your head ...
