The point of the tree (I guess it's big enough to call a tree instead
of a patch) being, from the POV of my funding sources etc., that 64GB
i386 has significant amounts of lowmem pressure alleviated and so the
machines are actually able to support various workloads for which they
were intended. If you've got >= 16GB of highmem, you should be
extremely interested in this patch.

It also increases maximum fs blocksize, which was its original purpose
as it was conceived by Hugh Dickins in his 2.4.6/2.4.7 patches (and his
2.4.x implementation was in many ways superior to my own).
