All the architectures properly set NEED_DMA_MAP_STATE now so we can safely add linux/pci-dma.h to linux/pci.h and remove the linux/pci-dma.h inclusion in arch's asm/pci.h Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Acked-by: Arnd Bergmann <arnd@arndb.de> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
