(Adding back the list)

I've updated the series (*) It's just a rebase from the previous one,
and one change: I don't allow resizing until after lmb_analyze() has run
since on various platforms, doing it too early such as when constructing
the memory array is risky as we haven't done the necessary lmb_reserve()
of whatever regions are unsuitable for allocation.

We can improve on that later, maybe by doing those reservations early,
before we add memory, or whatever, but that can wait.

Yinghai, is there any other chance you want me to do to the core ?

Another thing to add at some stage for ARM will be a default alloc base
in addition to limit, that constraints "standard" allocations.

(*) Usual place:

  git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc.git lmb

Cheers,
Ben.
