[PATCH] powerpc: node-aware dma allocations
Make sure dma_alloc_coherent allocates memory from the local node. This is important on Cell where we avoid going through the slow cpu interconnect. Note: I could only test this patch on Cell, it should be verified on some pseries machine by those that have the hardware.
