From f6331aaccbd980a49bff1559d66abcbd46af5b0a Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 1 Feb 2016 14:06:57 +0100 Subject: [PATCH] s390/stacktrace: add missing end marker save_stack_trace() did not write the ULONG_MAX end marker if there is enough space left. So simply follow x86 and arm64.
