I also prefer Josh's stack shift solution, as I personally believe that's a cleaner solution. But I went ahead and implemented Linus's version to get it working for ftrace. Here's the code, and it survived some preliminary tests.
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.
