You should be able to attach and detach CPUs depending on workload in your s390 Linux guest images :) One of the advantages of this patch is that it removes cpu_logical_map() and cpu_number_map() which people had a tendency to get wrong. It should also be easy to support more than BITS_PER_LONG cpus as there is no concept of online_cpu_map any more. Anton
