m68k doesn't clone it. This is from macsonic.c,
#define vdma_alloc(foo, bar) ((u32)foo)

Sure, but until that happens, it would be nice if the upstream kernel had
the MIPS repo versions of sonic.c, sonic.h and jazzsonic.c. That way it
might be possible for me to put together a patch for macsonic that both
archs are happy with.
It doesn't require a new DMA API to fix all the built-in ethernet ports on
68k Macs.
