[PATCH 00/31] Latest numa/core patches, v15

[Ingo Molnar <mingo@kernel.org>]

Hi,

This is the latest iteration of our numa/core tree, which
implements adaptive NUMA affinity balancing.

Changes in this version:

Performance figures:

Any review feedback, comments and test results are welcome!

For testing purposes I'd suggest using the latest tip:master
integration tree, which has the latest numa/core tree merged:

   git pull git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git master

(But you can also directly use the tip:numa/core tree as well.)

Thanks,

    Ingo
