I think you need to do something like I did for arch/arm/, where we have
separate trace functions for entry/exit to make sure that we invoke the
various helpers in the correct order (for example, you want to invoke all
the debug stuff *first* on entry, but *last* on exit).

If you mean syscall_trace_enter()/exit(), I will follow your suggestion
for readability.
