Fixup for commit 18dabf473e15850c0dbc8ff13ac1e2806d542c15. Changes to
dma_map_sg where done in asm-x86/dma-mapping_32.h, but were not mirrored
in include/asm-powerpc/dma-mapping.h

Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

Linus, I cannot build an arch/powerpc kernel without this patch.

Cheers,
g.

Oops, ignore this patch. It's doesn't change all the references, it
uses the wrong method for calculating dma_address and 2 other people
have already sent the fix for this.

/me puts on a paper bag

Olof Johansson already sent a patch out for this that had some other
fixes in it. I think Jens already applied it to his tree.
