Make it something like:

        static inline void set_stop_code(struct ptrace_context *ctx, int event)
        {
                ctx->stop_code = (event << 8) | SIGTRAP |
                        (event >= PTRACE_EVENT_SYSCALL_ENTRY &&
                         (ctx->options & PTRACE_O_TRACESYSGOOD) ? 0x80 : 0);
        }

and pick PTRACE_EVENT_* numbers so SYSCALL_{ENTRY,EXIT} are highest,
or something along those lines.


Thanks,
Roland
