So theoretically we could export that IORES_DESC* enum in an uapi header and
move kexec-tools to use that.

However, I'm fuzzy on how exactly the whole compatibility thing is done
with kexec-tools and the kernel. We probably would have to support
newer kexec-tools on an older kernel and vice versa so I'd guess we
should mark walk_iomem_res() deprecated so that people are encouraged to
upgrade to newer kexec-tools...


Hmmm.
