We have rethink about this, and found no strong reason to stay
with memory cgroup anymore.
We used to acquire pages number, exectime and locality together
from memory cgroup, to make thing easier for our numa balancer
module, as now we use the numa group approach, maybe we can just
move these accounting into cpu cgroups, so all these features
stay in one subsys and could be hierarchical :-)
