Well it past the second level of tests.

If this is the way we are going, I could add comments to the code and
apply it to my queue and run it through the rest of my test suite and
make it ready for the merge window. I may add a stable tag to it to go
back to where live kernel patching was added, as it fixes a potential
bug there.
