Date: Wed, 5 Aug 2009 14:08:23 +0900 From: FUJITA Tomonori <fujita.tomonori@....ntt.co.jp> To: linuxppc-dev@...ts.ozlabs.org, benh@...nel.crashing.org Cc: galak@...nel.crashing.orga, beckyb@...nel.crashing.org, linux-kernel@...r.kernel.org, mingo@...e.hu, fujita.tomonori@....ntt.co.jp Subject: [PATCH -v2 2/7] powerpc: remove swiotlb_pci_dma_ops Now swiotlb_pci_dma_ops is identical to swiotlb_dma_ops; we can use swiotlb_dma_ops with any devices. This removes swiotlb_pci_dma_ops.
