... and get it closer to working with unpatched mainline kernels

Makes it sound as if this was some sort of future aspiration. That's wrong: systemtap has essentially always worked with unpatched mainline kernels. (An issue that confuses some is that the user-space probing extensions require utrace. If you don't use that extension in your script, it does not matter.)
