There's a whole mess of CONFIG_CGROUP_* variables, feel free to turn off
those that your system doesn't actually need.

Make sure that you keep a backup kernel in case you turn off something you
shouldn't have.  In particular, systemd seems to want all sorts of cgroups for
no reason other than "because they're there".
