Thanks for the update. Just FYI, in parallel, Jiri Slaby (with help from a
few other people) (added to CC) is working on RFC on a per-thread patching
on top of the livepatching core, so that we can actually compare pros and
cons of both aproaches and implementations.

It might still take some time before its finalized and sent out as a RFC,
as I'd like it to also contain the "fake signal" task handling suggested
by Ingo. Miroslav is working on that part.
