The exception-trace facility on x86 and other architectures prints traces to dmesg whenever a user space application crashes. s390 has such a feature since ages however it is called userprocess_debug and is enabled differently. This patch makes sure that whenever one of the two procfs files /proc/sys/kernel/userprocess_debug /proc/sys/debug/exception-trace is modified the contents of the second one changes as well. That way we keep backwards compatibilty but also support the same interface like other architectures do. Besides that the output of the traces is improved since it will now also contain the corresponding filename of the vma (when available) where the process caused a fault or trap.
