Good catch ! I'll add a config ARCH_NO_VIRT_TO_BUS, but it would seem this is better done in arch/Kconfig and get rid of extraneous defs in arch/*/Kconfig. I can spin that patch, the only issue is merging logistics - our trees are not yet apt for such changes.

ARCH_NO_VIRT_TO_BUS was defined generically in the past in linux-next but the patch seems to have gone.
