The POC from my Plumber's talk is up here:
https://github.com/redgecombe/linux/commits/exec_only

It doesn't work with this KVM series though as I made changes on the KVM side. I
don't consider it ready for posting on the list yet. Luckily though, PeterZ's
switching of ftrace to text_poke(), and your exception table patchset will make
it easier when the time comes.

Right now I am re-doing the KVM pieces to get rid of the memslot duplication. I
am ending up having to touch a lot more KVM mmu code, and it's taken some time
to work through. Then I wanted get some more performance numbers before dropping
the RFC tag. So it may still be a bit before I can pick up the kernel text piece
again.
