This whole series is:

Acked-by: Andy Lutomirski <luto@kernel.org>

Now I just have to sucker someone into getting rid of
PARAVIRT_ADJUST_EXCEPTION_FRAME (by using stub entries) and the
overcomplicated syscall entry stuff. :) And whoever gets rid of
PARAVIRT_ADJUST_EXCEPTION_FRAME gets to wonder why it doesn't crash
and burn for NMIs on Xen, since I'm reasonably confident that it can't
possibly be correct.
