This requirement is an implementation detail of pvops on x86 (which
happens to require a specific new-ish hypercall), it is not a
fundamental property of the Xen architecture.

Since you would be starting afresh with a MIPS port it doesn't apply.

Even if there were a link the right thing to do would *still* be to
target both the newest kernel and hypervisor. There is no reason at all
to be starting a brand new project using such an old baseline.
