[RFC] Circular include dependencies

Having discovered some circular include dependencies in the ARM header
files which were causing build issues, I created a script to walk ARM
includes and report any similar issues found - which includes traversing
any referenced linux/ includes.

It identified the following two in include/linux/:

linux/mmzone.h <- linux/memory_hotplug.h <- linux/mmzone.h
linux/mmzone.h <- linux/topology.h <- linux/mmzone.h

Checking them by hand reveals that these are real. Whether they're
capable of causing a problem or not, I'm not going to comment on.
However, they're not a good idea and someone should probably look at
resolving the loops.
