xen: additional features for 3.19-rc0

- - Linear p2m for x86 PV guests which simplifies the p2m code, improves
  performance and will allow for > 512 GB PV guests in the future.

Thanks.

A last-minute, configuration specific issue was discovered with this change
which is why it was not included in my previous pull request.  This is now been
fixed and tested.

David
