Where's the rendezvous handler called?

Can we reuse the function from sys/amd64/vmm/vmm.c? If we can't share code, it might be a good idea to add a comment on top of the function like Copied from sys/amd64/vmm/vmm.c. Keep it in sync!.

arm64 doesn't implement a rendezvous operation.

In parallel I am working on merging this code with amd64 into sys/dev/vmm, so for now it is enough to try to minimize differences that appear with diff(1).
