I think that absence of these two are OK.

Netlink-diag is used to save state of netlink sockets, I doubt that
androind applications use one.

The soft-dirty thing is required for live-migration, which is not you
case as well, right?

Well, CRIU does work w/o the soft-dirty. It also does work w/o netlink-diag,
as Fedora-19 also doesn't have one, but criu package is available (and tested)
on it. If you have any problems making criu work on it -- feel free to ask.
