Here's a version of the isolated scheduler domain code that I mentioned in
an RFC on 7/22.  This patch applies on top of 2.6.8-rc2-mm1 (to include all
of the new arch_init_sched_domain code).  This patch also contains the 2
line fix to remove the check of first_cpu(sd->groups->cpumask)) that Jesse
sent in earlier.

Note that this has not been tested with CONFIG_SCHED_SMT.  I hope that my
handling of those instances is OK.
