Please copy the powerpc developers on powerpc patches.

especially ones like that ;)
Matthew has proposed that advansys should be dependent upon CONFIG_VIRT_TO_BUS. I don't think anyone's done a patch yet though.
(Actually, the code which you've altered there should probably be using CONFIG_VIRT_TO_BUS, too).
