From: Peter Xu <pet...@redhat.com>
kvm_physical_sync_dirty_bitmap() on the whole section is inaccurate, because
the section can be a superset of the memslot that we're working on. The result
is that if the section covers multiple kvm memslots, we could be doing the
synchronization for multiple times for each kvmslot in the section.
With the two helpers that we just introduced, it's very easy to do it right now
by calling the helpers.
