Gee the memory controller patchset is turning into a mess.

Hopefully it'll look a bit better once I do a big patch-folding but we
still have patches interesecting everywhere and now we have patches which
add a feature and later ones which take it away again.
But I don't think it's worth the time and risk of a huge
rip-up-and-refactor.
