From c42d8c7dbe596d849b43b7581bcc39b51f148c48 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Mon, 12 Sep 2016 14:37:20 +0200 Subject: s390: enable UBSAN This enables UBSAN for s390. We have to disable the null sanitizer as s390 code does access memory via a null pointer (the prefix page).
