You can find a new version of the hot swap cpu patch at:


The version for s390 (you need to first apply the 2.4.3 kernel
patch available on the IBM s390 Linux website) is at:


Many thanks to Heiko Carstens <Heiko.Carstens@de.ibm.com> for adding
s390 support and fixing a few bugs in the initial implementation.
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.
