SVN rev 204910 on 2010-03-09 13:08:57Z by jhb
Don't include disabled CPUs in the topology map. ULE assumes that all CPUs
in the topology map were present and enabled. Booting a system with
hyperthreading and at least one CPU would cause ULE to attempt to use a
disabled CPU when rebalancing load resulting in a panic. This is a direct
commit to 7 as the topology code is different in 8 and later.
