There are no platform specific header files other than asm/amigahw.h and
asm/mvme147hw.h, currently only holding register address definitions.
Would it be OK to add m68k_virt_to_bus() in there if it can't remain in
asm/virtconvert.h, Geert?

In that case, I would just leave it under the current name and not change
m68k at all. I don't like the m68k_virt_to_bus() name because there is
not anything CPU specific in what it does, and keeping it in a common
header does nothing to prevent it from being used on other platforms
either.

Fair enough.

32bit powerpc is a different matter though.

It's similar, but unrelated. The two apple ethernet drivers
(bmac and mace) can again either get changed to use the
dma-mapping interfaces, or get a custom pmac_virt_to_bus()/
pmac_bus_to_virt() helper.

Hmmm - I see Finn had done the DMA API conversion on macmace.c which
might give some hints on what to do about mace.c ... no idea about
bmac.c though. And again, haven't got hardware to test, so custom
helpers is it, then.

Ok.

Again, no platform specific headers to shift renamed helpers to, so may 
as well keep this as-is.
