Ktap almost gets into 3.13

Well, a whole lot of things. First and foremost it's just not the user interface I would expect. Why, exactly, do I have to give a command that it has to run, like "sleep 10", to given an upper-bound to its running? Why not just give me a "-t 10". Then the data it gives is all sample-based. Sampling is nice, but I'd find it a whole lot more useful to be able to have performance counters being read at every hit to an ftrace trace point. But I wouldn't need perf for that. The way I see it is that perf is like a better gprof. That's just not powerful enough for me. Then again, I'm not a regular user and I might have a very peculiar way of solving problems.
