Actually I've only now realized that this isn't a real problem right now: PV can't use SMAP (we don't provide a virtualized version of it), and HVM/PVH can't use multicalls (which may have to change for PVH Dom0, so having the change in place is helpful anyway), so the whole in-kernel logic to collect and issue batches should be unreachable there. But perhaps the commit message would benefit from a little bit of re-wording.
