And you did mention offlining some CPUs above. The folloiwng patch
(from Lai Jiangshan) is needed to handle this case.
btw on x86... don't offline CPUs if you want to save power.. it doesn't.
(at least not during idle.. and when you're busy it might save power, but it won't save you energy normally)
