Christoph Lameter 7a88d7a8f4 s390: use kbuild.h instead of defining macros in asm-offsets.c
s390 has a strange marker in DEFINE.  Undefine the DEFINE from kbuild.h and
define it the way s390 wants it to preserve things as they were.

May be good if the arch maintainer could go over this and check if this
workaround is really necessary.
