Here comes the minimal NUMA scheduler built on top of the O(1) load
balancer rediffed for 2.5.53 with some changes in the core part. As
suggested by Michael, I added the cputimes_stat patch, as it is
absolutely needed for understanding the scheduler behavior.

The three patches:
01-numa-sched-core-2.5.53-24.patch: core NUMA scheduler infrastructure
  providing a node aware load_balancer. Cosmetic changes + more comments.

02-numa-sched-ilb-2.5.53-21.patch: initial load balancing, selects
  least loaded node & CPU at exec().

03-cputimes_stat-2.5.53.patch: adds back to the kernel per CPU user
  and system time statistics for each process in /proc/PID/cpu. Needed
  for evaluating scheduler behavior and performance of tasks running
  on SMP and NUMA systems.
