The isolcpus= boot param is donkey shit and needs to die. cpuset _used_
to be able to fully replace it, but with the advent of cgroup 'feature'
this got lost.

And instead of fixing it, you're making it _far_ worse. You completely
removed all the bits that allow repartitioning the scheduler domains.

Mike is completely right, full NAK on any such approach.
