Commit fb34a08c ("tracing: Add trace events for each syscall entry/exit") changed the lowlevel API to ftrace syscall tracing but did not update s390 which started making use of it recently. This broke the s390 build, as reported by Paul Mundt. Update the callbacks with the syscall number and the syscall return code values. This allows per syscall tracepoints, syscall argument enumeration /debug/tracing/events/syscalls/ and perfcounters support and integration on s390 too. Reported-by:
