Ok, I merged the patch from SystemTAP to help them parse the markers
section, but seeing the violent objections it gets, I guess they will
have to figure out another way to parse it. Let's drop the
allow-userspace-applications-to-use-markerh-to-parse-the-markers-section-in-the-kernel-binary.patch

Good catch, will fix. I do already have more than one, don't worry ;)
