So I haven't been following too closely, but I'm also a bit skeptical
about the new custom flag thing. OTOH, I'd really like to see those
first cleanups go in soon, especially patch 6 - which not only makes the
ram use a bit more accurate, it also avoids ~10000 calls of strlen() on
cache-cold memory during boot.

So, FWIW, you have my Acked-by for patches 1 through 11, and I hope
those can be picked up before the next merge window. But the remaining
ones seem to still require some discussion.
