Kamezawa-San, Andrew, I think patches 1 and 2 are ready to go. Andrew they remove the cgroup member from struct page and will help reduce the overhead for distros that care about 32 bit systems and also help with performance (in my runs so far). I would recommend pushing 1 and 2 right away to -mm followed by the other performance improvements.
