Hi,
  The attached patch-pair fix migration in the case
where you are using huge pages but you have a RAM size
which is not a multiple of the huge page size.
It's unfortunately legal so there might be VMs out there
that already have it, and it turns out it used to work,
but it broke, probably when I added the support for hugepages
in postcopy.

Here I:
   a) Fix it for normal migration
   b) Ban it for postcopy, since postcopy+hugepage was new
     recently anyway and it's a non-trivial fix.
