[PATCH] Last DMA_xBIT_MASK cleanups
These are the last conversions of pci_set_dma_mask(), pci_set_consistent_dma_mask() and pci_dma_supported() to use DMA_xBIT_MASK constants from linux/dma-mapping.h Signed-off-by: Tobias Klauser <tklauser@nuerscht.ch> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
