This patchset uses these
+               pv_mmu_ops.flush_tlb_others = xen_flush_tlb_others;
+               pv_cpu_ops.cpuid = xen_cpuid;

These are still in the code:

        pv_info = xen_info;
        pv_init_ops = xen_init_ops;
        pv_apic_ops = xen_apic_ops;
        pv_time_ops = xen_time_ops;

And the x86_init,apic, and smp_ops ops are still in force.

This is just the first step so there might be some other ones
that are needed that I failed to enumerate.

We are at the infancy period.
