Actually, this patch was necessary when my kdump used "usable-memory"
properties in "memory" nodes, as on ppc64, to limit the usable memory
regions that can be used by crash dump kernel.
Since then, I've moved to the approach of using "mem=" kernel parameter,
then introducing a new property, "linux,usable-memory-range," under /chosen
and now we don't need this patch any more.

So, we can drop it but I still believe that it is buggy.
