arch/mips/mm/dma-default.c is the implementation of the DMA API as
documented in the kernel; it needs to bang on the caches for non-coherent
I/O so will have to continue using the old functions though I may change
the function names.  sgiseeq I already fixed, the rest is being fixed
once as I'm writing this.
