Paul Jackson d10689b68a [PATCH] cpu_exclusive sched domains on partial nodes temp fix
This keeps the kernel/cpuset.c routine update_cpu_domains() from
invoking the sched.c routine partition_sched_domains() if the cpuset in
question doesn't fall on node boundaries.

I have boot tested this on an SN2, and with the help of a couple of ad
hoc printk's, determined that it does indeed avoid calling the
partition_sched_domains() routine on partial nodes.

I did not directly verify that this avoids setting up bogus sched
domains or avoids the oops that Hawkes saw.

This patch imposes a silent artificial constraint on which cpusets can
be used to define dynamic sched domains.

This patch should allow proceeding with this new feature in 2.6.13 for
the configurations in which it is useful (node alligned sched domains)
while avoiding trying to setup sched domains in the less useful cases
that can cause the kernel corruption and oops.
