Hi Chris & Daniel,

   Thanks for your comments. Following are my understandings about
the changes needed for this patch:

1> We do not need the guard page anymore between different VMs. For
the very last physical GTT entry, let's keep it pointing to a guard
page.

2> To reserve the GMs in our balloon code, drm_mm_reserve_node() is
preferred than the current drm_mm_insert_node_in_range_generic().

   Am I correct? Please correct me if anything wrong. Thanks! :)

Agreed. If you care to respin the patch, I'll see if anything else
alarms me ;-)

Got it. Thank you, Chris.
-Chris
