This ordering makes it quite hard to revert individual patches after
merging in case they are faulty, because we end up with a tree state
that has no soft limit implementation at all, or a newly broken one.
Could you reorder the series such that each patch leaves the tree in a
sane state?
I.e. also don't introduce an endless loop in the page allocator
through one patch and fix it later in another one ;) Noone will be
able to remember these cross-dependencies in a couple of weeks.
Thanks!
