David also mentioned this but "11" is not a very good rendering of 1:1.
I know we use this internally within both Xen and Linux but perhaps at
the hypercall API layer we could use "identity" or something instead?

It might be worth trying to include a word which implies "in addition to
the mapping you asked for" as well, for clarity.
