[PATCH 0/2] ubsan for s390

This patch set enables ubsan for s390.

We have to fence some files and can then enable
ARCH_HAS_UBSAN_SANITIZE_ALL. (patch 2)

We have to disable the null pointer sanitizer as
we use the S390_lowcore macro to access several
memory location after address 0 (patch 1)

If patch 1 is ok, is the s390 tree the right place
also for patch1?

Christian Borntraeger (2):
ubsan: allow to disable the null sanitizer
s390/ubsan: enable UBSAN for s390
