So, this was stable in both pre and postcopy, at least until I stopped postcopy and hit my BUG_ON in gmap_shadow_notify_pmd. For some reason migration of my 10g l2 with small and big l3 takes 60s instead of ~30s now. For the next version it will need some more love. The second patch will be in the next version one way or another. I just felt that gmap_pte_op_fixup looked weird in a pmd handling function.
