s390: show_registers() should not map user space addresses to kernel symbols
It doesn't make sense to map user space addresses to kernel symbols when show_registers() prints a user space psw. So just skip the translation part if a user space psw is handled. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
