This is the first part of the minimal NUMA scheduler built on top of
the O(1) load balancer. It is rediffed for 2.5.52 and contains a small
bugfix in build_node_data().

The two patches are:

01-numa-sched-core-2.5.52-23.patch: core NUMA scheduler infrastructure
  providing a node aware load_balancer.

02-numa-sched-ilb-2.5.52-21.patch: initial load balancing, selects
  least loaded node & CPU at exec().
