Patch to make 2.4.13 compile on s390

[Pete Zaitcev <zaitcev@redhat.com>]

Someone broke s390 and s390x, it did not even compile.
Do we actually have a maintainer for that thing?
Or do we blindly apply whatever IBM bestows?

MAINTAINERS lists some e-mails and lists for s390, but I did
not receive any replies from those people. Must have
been eaten by evil Lotus or something...
