This should be fixed trivially in the very same way as for x86_64, i.e. something like
diff --git a/arch/s390/kernel/binfmt_elf32.c b/arch/s390/kernel/binfmt_elf32.c index f1e40ca..4b5432d 100644 --- a/arch/s390/kernel/binfmt_elf32.c +++ b/arch/s390/kernel/binfmt_elf32.c @@ -199,5 +199,6 @@ cputime_to_compat_timeval(const cputime_t cputime, struct compat_timeval *value) value->tv_sec = cputime / 1000000; } +extern void arch_randomize_brk(void); #include "../../../fs/binfmt_elf.c"
right? Maybe this would be needed for other architectures too :( I will check this. I'd really like the patch go in, so that we have really full randomization finally.

I agree that it is a total mess. We'd need someone brave enough to rewrite this crap :/
