Hello everyone, This is an updated version of the DMA-mapping framework redesign preparation patches, which resolves issues pointed by Linus: https://lkml.org/lkml/2012/3/23/305 These patches are the first step to clean up a bit dma-mapping api and introduce support for architecture specific performance improving hints in a generic way. For more information please refer to the thread with the first version of the patches: https://lkml.org/lkml/2011/12/23/97 Best regards Marek Szyprowski Samsung Poland R&D Center Patch summary: Andrzej Pietrasiewicz (8): X86 & IA64: adapt for dma_map_ops changes MIPS: adapt for dma_map_ops changes PowerPC: adapt for dma_map_ops changes SPARC: adapt for dma_map_ops changes Alpha: adapt for dma_map_ops changes SH: adapt for dma_map_ops changes Microblaze: adapt for dma_map_ops changes Unicore32: adapt for dma_map_ops changes Marek Szyprowski (6): common: dma-mapping: introduce alloc_attrs and free_attrs methods Hexagon: adapt for dma_map_ops changes common: dma-mapping: remove old alloc_coherent and free_coherent methods common: dma-mapping: introduce mmap method common: DMA-mapping: add WRITE_COMBINE attribute common: DMA-mapping: add NON-CONSISTENT attribute Documentation/DMA-attributes.txt | 19 +++++++++++++++++++ arch/alpha/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/alpha/kernel/pci-noop.c | 10 ++++++---- arch/alpha/kernel/pci_iommu.c | 10 ++++++---- arch/hexagon/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/hexagon/kernel/dma.c | 9 +++++---- arch/ia64/hp/common/sba_iommu.c | 11 ++++++----- arch/ia64/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/ia64/kernel/pci-swiotlb.c | 14 +++++++++++--- arch/ia64/sn/pci/pci_dma.c | 9 +++++---- arch/microblaze/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/microblaze/kernel/dma.c | 10 ++++++---- arch/mips/cavium-octeon/dma-octeon.c | 12 ++++++------ arch/mips/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/mips/mm/dma-default.c | 8 ++++---- arch/powerpc/include/asm/dma-mapping.h | 24 ++++++++++++++++-------- arch/powerpc/kernel/dma-iommu.c | 10 ++++++---- arch/powerpc/kernel/dma-swiotlb.c | 4 ++-- arch/powerpc/kernel/dma.c | 10 ++++++---- arch/powerpc/kernel/ibmebus.c | 10 ++++++---- arch/powerpc/kernel/vio.c | 14 ++++++++------ arch/powerpc/platforms/cell/iommu.c | 16 +++++++++------- arch/powerpc/platforms/ps3/system-bus.c | 13 +++++++------ arch/sh/include/asm/dma-mapping.h | 28 ++++++++++++++++++---------- arch/sh/kernel/dma-nommu.c | 4 ++-- arch/sh/mm/consistent.c | 6 ++++-- arch/sparc/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/sparc/kernel/iommu.c | 10 ++++++---- arch/sparc/kernel/ioport.c | 18 ++++++++++-------- arch/sparc/kernel/pci_sun4v.c | 9 +++++---- arch/unicore32/include/asm/dma-mapping.h | 18 ++++++++++++------ arch/unicore32/mm/dma-swiotlb.c | 18 ++++++++++++++++-- arch/x86/include/asm/dma-mapping.h | 26 ++++++++++++++++---------- arch/x86/kernel/amd_gart_64.c | 11 ++++++----- arch/x86/kernel/pci-calgary_64.c | 9 +++++---- arch/x86/kernel/pci-dma.c | 3 ++- arch/x86/kernel/pci-nommu.c | 6 +++--- arch/x86/kernel/pci-swiotlb.c | 17 +++++++++++++---- arch/x86/xen/pci-swiotlb-xen.c | 4 ++-- drivers/iommu/amd_iommu.c | 10 ++++++---- drivers/iommu/intel-iommu.c | 9 +++++---- drivers/xen/swiotlb-xen.c | 5 +++-- include/linux/dma-attrs.h | 2 ++ include/linux/dma-mapping.h | 13 +++++++++---- include/xen/swiotlb-xen.h | 6 ++++-- 45 files changed, 355 insertions(+), 198 deletions(-) -- 1.7.1.569.g6f426
