I've been wanting to do this for some time and given all the recent
API updates now seems like a pretty good opportunity. Verified
freezer and blkcg. The conversions are mostly straight forward but
I'd much appreciate acks from controller maintainers.

The patch is on top of

cgroup/for-3.12 61584e3f4 ("cgroup: Merge branch 'for-3.11-fixes' into for-3.12")
+ [1] cgroup: use cgroup_subsys_state as the primary subsystem interface handle
+ [2] cgroup: make cgroup_event specific to memcg

and available in the following git branch.
