From 762afb7317b1987fa0851135fe4f2947f68c3c2a Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Tue, 4 Aug 2009 19:08:22 +0000 Subject: powerpc: Remove addr_needs_map in struct dma_mapping_ops This patch adds max_direct_dma_addr to struct dev_archdata to remove addr_needs_map in struct dma_mapping_ops. It also converts dma_capable() to use max_direct_dma_addr. max_direct_dma_addr is initialized in pci_dma_dev_setup_swiotlb(), called via ppc_md.pci_dma_dev_setup hook.
