These APIs are valid only for

Anything wanting a generic translation from

call iopa() directly until somebody drives a generic
translation
API into the kernel.

Thanks, I missed that.

BTW, it was pointed out to me that the changesets I made to linux-2.4
to merge the 2.6 virt_to_* method have been merged back into current
linuxppc-2.4 and linuxppc_2_4_devel.

So, all current devel trees have the API correct implementation now.

Now somebody needs to create a nice device-to-device DMA and bus
address translation API. :)
