Hi,

this is v2 of the memcg_kmem hooks refactoring (RFC/v1 link at the end).
This just rebases the refactoring patches 1 and 2 so they can start to
be exposed to -next and other work on can base on that.  I'm not
including the kmem_cache_charge() patch here until we have a more
finished user than my previous unfinished attempt.
