[S390] Enable exception traces by default
Enable exception traces by default so that early user space breakage (e.g. broken code in initrd) can be easily indentified. If not needed afterwards it can be disabled by writing '0' in one of these two files: /proc/sys/kernel/userprocess_debug /proc/sys/debug/exception-trace Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
