From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>

Hi,
  This patch set reworks the way the vhost code handles changes in
physical address space layout that came from a discussion with Igor.

Its intention is to simplify a lot of the update code,
and to make it easier for the postcopy+shared code to
do the hugepage alignments that are needed.

Instead of inserting/removing each section during the add/del
callbacks of the listener, we start afresh and build a list
from the add and nop callbacks, then at the end compare the list
we've built with the exisiting list.

v7
  Avoid calling memcmp(NULL,NULL,0) in region list compare

v6
  Tidy ups from Igor
  The biggest change is moving the 'Move log_dirty check' to be
  the last patch in the set.
