Obviously the hope is that the really invasive ones will 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.
