It's not just possible, it appears to be exactly what happens.
I guess it makes sense that RIP gets advanced before HLT begins to
wait.
It does. Good, it simplifies the patch.
btw, this is how kvm emulates HLT - first we advance rip, then we
sleep the vcpu.
Yes, I assume the hardware updates RIP immediately after fetching the
instruction. That's at least how some simpler architectures I'm aware
of work.
