There was a new xc_gnttab_munmap which needed converting. BTW, contrary to what every single commit message here says I'm actually build testing on: xen with my other patches from this mega series, 4.6, 4.1, 4.0, 4.5, 4.4, 4.3, 4.2 and on my dev xen with pvbuilder forced to on. I'm just going to drop all these "Build tested.." from the commit messages. (the strange version ordering is so I test the different API classes first and fail early on problems and then fill in the gaps).
