  "message": "dma: add dma_*map*_attrs() interfaces\n\nIntroduce new interfaces, dma_*map*_attrs(), for passing architecture-specific\nattributes when memory is mapped and unmapped for DMA.  Give the interfaces\ndefault implementations which ignore attributes.  Also introduce the\ndma_{set|get}_attr() interfaces for setting and retrieving individual\nattributes.  Define one attribute, DMA_ATTR_WRITE_BARRIER, in anticipation of\nits use by ia64/sn.  Select whether architectures implement arch-specific\nversions of the dma_*map*_attrs() interfaces via HAVE_DMA_ATTRS in Kconfig.\n\n[markn@au1.ibm.com: dma_{set,get}_attr() have to be static inline]\nSigned-off-by: Arthur Kepner \u003cakepner@sgi.com\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Jesse Barnes \u003cjbarnes@virtuousgeek.org\u003e\nCc: Jes Sorensen \u003cjes@sgi.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Roland Dreier \u003crdreier@cisco.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: David Miller \u003cdavem@davemloft.net\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Grant Grundler \u003cgrundler@parisc-linux.org\u003e\nCc: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nSigned-off-by: Mark Nelson \u003cmarkn@au1.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
