So I\nCC\u0027ed this to KVM camp. Comments are appreciated.\n\nA pointer to dma_mapping_ops to struct dev_archdata is added. If the\npointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it\u0027s\nNULL, the system-wide dma_ops pointer is used as before.\n\nIf it\u0027s useful for KVM people, I plan to implement a mechanism to register\na hook called when a new pci (or dma capable) device is created (it works\nwith hot plugging). It enables IOMMUs to set up an appropriate\ndma_mapping_ops per device.\n\nThe major obstacle is that dma_mapping_error doesn\u0027t take a pointer to the\ndevice unlike other DMA operations. So x86 can\u0027t have dma_mapping_ops per\ndevice. Note all the POWER IOMMUs use the same dma_mapping_error function\nso this is not a problem for POWER but x86 IOMMUs use different\ndma_mapping_error functions.\n\nThe first patch adds the device argument to dma_mapping_error. The patch\nis trivial but large since it touches lots of drivers and dma-mapping.h in\nall the architecture.\n\nThis patch:\n\ndma_mapping_error() doesn\u0027t take a pointer to the device unlike other DMA\noperations. So we can\u0027t have dma_mapping_ops per device.\n\nNote that POWER already has dma_mapping_ops per device but all the POWER\nIOMMUs use the same dma_mapping_error function. x86 IOMMUs use device\nargument.\n\n[akpm@linux-foundation.org: fix sge]\n[akpm@linux-foundation.org: fix svc_rdma]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix bnx2x]\n[akpm@linux-foundation.org: fix s2io]\n[akpm@linux-foundation.org: fix pasemi_mac]\n[akpm@linux-foundation.org: fix sdhci]\n[akpm@linux-foundation.org: build fix]\n[akpm@linux-foundation.org: fix sparc]\n[akpm@linux-foundation.org: fix ibmvscsi]\nSigned-off-by: FUJITA Tomonori \u003cfujita.tomonori@lab.ntt.co.jp\u003e\nCc: Muli Ben-Yehuda \u003cmuli@il.ibm.com\u003e\nCc: Andi Kleen \u003candi@firstfloor.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "02d15c43225afb2ebb6d700144285175a1c4abd9", "tree": "fd0e21f29c7f026514cbb36b2ecdcbfdf341763a", "parents": [ "cb9fbc5c37b69ac584e61d449cfd590f5ae1f90d" ], "author": { "name": "Randy Dunlap", "email": "randy.dunlap@oracle.com", "time": "Tue Apr 29 01:00:35 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Apr 29 08:06:12 2008 -0700" }, "message": "doc: fix DMA-API function parameters\n\nFix kernel bugzilla #10388.\n\nDMA-API.txt has wrong argument type for some functions.

That\u0027s not wholly obvious\n to folk reading _only_ the \"new\" DMA-API.txt writeup.\n\n - Buffers allocated by dma_alloc_coherent() may not be completely\n free of coherency concerns ... some CPUs also have write buffers\n that may need to be flushed.\n\n - Cacheline coherence issues are now mentioned as being among issues\n which affect dma buffers, and complicate/prevent using of static and\n (especially) stack based buffers with the DMA calls.\n\nI don\u0027t think many drivers currently need to worry about flushing write\nbuffers, but I did hit it with one SOC using external SDRAM for DMA\ndescriptors: without explicit writebuffer flushing, the on-chip DMA\ncontroller accessed descriptors before the CPU completed the writes.\n\nSigned-off-by: David Brownell \u003cdbrownell@users.sourceforge.net\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n" }, { "commit": "d533f671852cc4e481ea7070aa1a3b6fc75b8e44", "tree": "970419f90c377dbcfb4d8726460d62ad8c8fbac4", "parents": [ "9de75d110c9681d4aaa7fe87b8db99d5562012a2" ], "author": { "name": "Tobias Klauser", "email": "tklauser@nuerscht.ch", "time": "Sat Sep 10 00:26:46 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sat Sep 10 10:06:28 2005 -0700" }, "message": "[PATCH] Spelling fixes for Documentation/\n\nThe attached patch fixes the following spelling errors in Documentation/\n - double \"the\"\n - Several misspellings of function/functionality\n - infomation\n - memeory\n - Recieved\n - wether\nand possibly others which I forgot ;-)\nTrailing whitespaces on the same line as the typo are also deleted.\n\nSigned-off-by: Tobias Klauser \u003ctklauser@nuerscht.ch\u003e\nSigned-off-by: Domen Puncer \u003cdomen@coderock.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
