Subject: [PATCH 1/1] asm-generic/io.h: check CONFIG_VIRT_TO_BUS

Make asm-generic/io.h check CONFIG_VIRT_TO_BUS before defining
virt_to_bus() and bus_to_virt(), otherwise it's easy to accidentally
have a silently failing incorrect direct mapped definition rather then
no definition at all.

Good catch!

Hi Arnd,

Would you like me to include this in the meta patchset or is it okay for
you to take it through the asm-generic tree? (I can resend separately if
you like)

Thanks
James
