If I understand correctly what you're asking, the (current) answer is in
the Linux patch, here:
http://bugs.xenproject.org/xen/mid/%3C1384811922-14642-2-git-send-email-ufimtseva@gmail.com%3E
which uses num_possible_cpus()
http://lxr.linux.no/linux+v3.12/+code=num_possible_cpus
to size all the three arrays.
