New PTRACE_EVENT_STOP is the first event which has no corresponding PTRACE_O_TRACE option. If we will ever want to add another such option, its PTRACE_EVENT's value will collide with PTRACE_EVENT_STOP's value. This patch changes PTRACE_EVENT_STOP value to prevent this. While at it, added a comment - the one atop PTRACE_EVENT block, saying "Wait extended result codes for the above trace options", is not true for PTRACE_EVENT_STOP.
