Re: PowerPC equivalent to dma_mmap_writecombine()?

quoted

There are no dma_mmap_x() functions in arch/powerpc.  Can someone  
tell me what the powerpc
equivalent to dma_mmap_writecombine() is?

Not sure exactly what arm does here, but it sounds like you want
to call remap_pfn_range with the _PAGE_NO_CACHE bit set in the
protection flags, and _PAGE_GUARDED not set.

Either that, or just map it as normal cache-coherent DMA
memory.
