Nadav, want to resubmit your series? IIRC the only thing wrong with it was
that it was a big change and we wanted a simpler fix to backport. But
that’s all done now, and I, at least, rather liked your code. :)

I guess since it was based on your ideas…

Anyhow, the only open issue that I have with v2 is Peter’s wish that I would
make kgdb use of poke_text() less disgusting. I still don’t know exactly
how to deal with it.

Perhaps it (fixing kgdb) can be postponed? In that case I can just resend
v2.

Oh man, I completely forgot about kgdb :/

Also, would it be possible to entirely remove that kmap fallback path?

Let me see what I can do about it.

My patches had several embarrassing bugs. I’m fixing and will resend later,
hopefully today.
