Hi Isaku,

   Thanks for continuing to work on this.  These patches seem to work
fine for me, I booted with a 64GB dom0.  Are there any known outstanding
issues with these patches (since they were sent as an RFC) or should we
add them to the tree?  It would certainly be nice to remove the dom0
memory limitations.  Thanks,

        Alex
