Scott's patch 1c98025c "Dynamic DMA zone limits" changed dma_direct_alloc_coherent() to start using dev->coherent_dma_mask. That seems fair enough, but it exposes the fact that some of the drivers we care about on IBM platforms aren't setting the coherent mask. The proper fix is to have drivers set the coherent mask and also have the platform code honor it. For now, just restrict the dynamic DMA zone limits to the platforms that need it. Signed-off-by:
