Rewrite kvm_hv_flush_tlb()/send_ipi_vcpus_mask() making them cleaner and somewhat more optimal. hv_vcpu_in_sparse_set() is converted to sparse_set_to_vcpu_mask() which copies sparse banks u64-at-a-time and then, depending on the num_mismatched_vp_indexes value, returns immediately or does vp index to vcpu index conversion by walking all vCPUs. To support the change and make kvm_hv_send_ipi() look similar to kvm_hv_flush_tlb() send_ipi_vcpus_mask() is introduced. Suggested-by:
