Subject: mm: memcontrol: re-use node VM page state enum
The current duplication is a high-maintenance mess, and it's painful to
add new items or query memcg state from the rest of the VM.
This increases the size of the stat array marginally, but we should aim to
track all these stats on a per-cgroup level anyway.
