Nick has tossed out and redone all the scheduler patches from -mm4, but I
assume it's all pretty much the same.

At http://www.zip.com.au/~akpm/linux/patches/stuff/mbligh.gz is a rollup
(against 2.6.12-rc1) of

sched2-fix-schedstats-warning.patch
sched2-cleanup-wake_idle.patch
sched2-improve-load-balancing-pinned-tasks.patch
sched2-reduce-active-load-balancing.patch
sched2-fix-smt-scheduling-problems.patch
sched2-add-debugging.patch
sched2-less-aggressive-idle-balancing.patch
sched2-balance-timers.patch
sched2-tweak-affine-wakeups.patch
sched2-no-aggressive-idle-balancing.patch
sched2-balance-on-fork.patch
sched2-schedstats-update-for-balance-on-fork.patch
sched2-sched-tuning.patch
sched2-sched-domain-sysctl.patch
