This confused me a bit. I thought we didn't support paravirtualized flush_tlb_multi() from reading earlier in the series. But, it seems like that might be Xen-only and doesn't apply to KVM and paravirtualized KVM has no problem supporting flush_tlb_multi(). Is that right? It might be good to include some of that background in the changelog to set the context.
