The SPARC tree carries the same broken code -- is
this just a case of code copying, or are there
actual SPARC machines with such broken trees?

There have been many cases of missed or even erroneous
properties on sparc tree, but I am not too sure about
the cell counting cases.

Let's do this, once the consolidation is done keeping
behavior as-is, give me a patch to review that changing
the cell counting bits and I'll verify it against
all the machines I have here plus some OFW tree dumps.
