From: FUJITA Tomonori Date: Tue, 4 Aug 2009 19:08:23 +0000 (+0000) Subject: powerpc: Remove swiotlb_pci_dma_ops X-Git-Tag: v2.6.32-rc1~675^2~38 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3702977fa7d1a1a95caa387121fa7c9f4cae35f3;p=platform%2Fupstream%2Fkernel-adaptation-pc.git 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.
