I have been looking at this patchset and tried it out; it has a build
failure because of a naming conflict:

/home/hpa/kernel/linux-2.6-tip.range/drivers/pci/hotplug/ibmphp_res.c:43: error:
conflicting types for ‘add_range’
/home/hpa/kernel/linux-2.6-tip.range/include/linux/range.h:9: note:
previous declaration of ‘add_range’ was here

"add_range" is static.

This makes me concerned that the naming is too generic.  In particular,
we tend to prefer naming of the type subsystem_function(), so in this
case range_add() might be a more suitable naming scheme.

I'm going to spend more time on this patchset.
