AFAICS, this should remove the circular dependency you originally
reported.  I'll revert the two cpuset commits for now.

So I liked his patches in that we would be able to go back to
synchronous sched_domain building.

Ah, yeah, that's a separate issue but didn't we intentionally make
that asynchronous?  IIRC, cpuset migration can take a really long time
when the memory migration is turned on and doing that synchronously
could mess up the system.

Thanks.
