v2:
- patch 2: use "1" instead of "sizeof(bool)" for VMSTATE_UNUSED
  because sizeof(bool) can be >1 depends on definition [Dave]

The first patch is the important one.  It should fix up a migration
issue that Dave reported between 3.1<->4.0.  The second patch is born
only because I noticed it when drafting patch 1 and I think we can
probably do that too together as a fixup to the scalable patchset for
4.0.

Please have a look, thanks.

Ping - just want to make sure this series won't miss 4.0.  Thanks,
