Well, native would fall back to using the existing arch/i386 versions of those functions, so that's reasonably straightforward. There'll need to be a bit of internal rearrangement so that the Xen code can call in to do things like set up the pda/gdt and other bits of CPU state. I don't think IPI is especially interesting in itself, is it? It's a necessary mechanism to implement smp_call_function(), but Xen can do IPI without having to invoke any of the existing apic-based IPI code. The other main user of IPI is cross-cpu tlb shootdown, but Xen has much more efficient mechanisms than IPI for that (so we'll need to make the tlb pv_ops interface a little wider to pass down a cpuset).
