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": "8948896c9e098c6fd31a6a698a598a7cbd7fa40e", "tree": "465a4d93c8becb0b2e4750cc1286391916f887b5", "parents": [ "bf5927d84e70d522f234ca247b27d27c63878b93" ], "author": { "name": "Tom Tucker", "email": "tom@opengridcomputing.com", "time": "Wed May 28 15:14:02 2008 -0500" }, "committer": { "name": "Tom Tucker", "email": "tom@opengridcomputing.com", "time": "Wed Jul 02 15:02:02 2008 -0500" }, "message": "svcrdma: Change WR context get/put to use the kmem cache\n\nChange the WR context pool to be shared across mount points.

In the case of a request, several\ncalculations and tests involving pos are unnecessary. In the case of a\nreply, several calculations and tests involving pos are incorrect (the\ncode tests pos against the reply xdr buf\u0027s len field, which is always\n0 at the time rpcrdma_convert_iovs is executed). This change removes\nthe incorrect/unnecessary calculations and tests involving pos.\n\nThis fixes an observed problem when reading certain file sizes over\nNFS/RDMA.\n\nSigned-off-by: Tom Tucker \u003ctom@opengridcomputing.com\u003e\nSigned-off-by: Tom Talpey \u003ctalpey@netapp.com\u003e\nSigned-off-by: James Lentini \u003cjlentini@netapp.com\u003e\nSigned-off-by: Trond Myklebust \u003cTrond.Myklebust@netapp.com\u003e\n" }, { "commit": "cfcb43ff7ce28f347a39e1a7519e01850b588718", "tree": "3f21947e64316de5499c38d6c76a6ae3dd48996f", "parents": [ "4c1fe2f78a08e2c514a39c91a0eb7b55bbd3c0d2" ], "author": { "name": "James Lentini", "email": "jlentini@netapp.com", "time": "Mon Nov 26 12:42:44 2007 -0500" }, "committer": { "name": "Trond Myklebust", "email": "Trond.Myklebust@netapp.com", "time": "Mon Nov 26 16:21:19 2007 -0500" }, "message": "SUNRPC: remove NFS/RDMA client\u0027s binary sysctls\n\nSupport for binary sysctls is being deprecated in 2.6.24.
