      "message": "dma-ops: Remove flush_write_buffers() in dma-mapping-common.h\n\nThis moves flush_write_buffers() in\nasm-generic/dma-mapping-common.h to\narch/x86/kernel/pci-nommu.c.\n\nThe purpose of this patch is that, we can avoid defining NULL\nflush_write_buffers() on IA64 and SPARC.\n\ndma-mapping-common.h is used by X86 and IA64 (and SPARC soon)\nbut only X86 with CONFIG_X86_OOSTORE or CONFIG_X86_PPRO_FENCE\nactually uses flush_write_buffers(). CONFIG_X86_OOSTORE or\nCONFIG_X86_PPRO_FENCE is usable with only kernel/pci-nommu.c\n(that is, not usable with other X86 IOMMU implementations such\nas SWIOTLB, VT-d, etc) so we can safely move\nflush_write_buffers() in asm-generic/dma-mapping-common.h to\narch/x86/kernel/pci-nommu.c.\n\nThe further discussion is:\n\n  http://lkml.org/lkml/2009/6/28/104\n\nSigned-off-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nAcked-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: davem@davemloft.net\nCc: tony.luck@intel.com\nCc: fenghua.yu@intel.com\nLKML-Reference: \u003c1249872797-1314-2-git-send-email-fujita.tomonori@lab.ntt.co.jp\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"
