*	iommu-api: Remove iommu_{un}map_range functions	Joerg Roedel	2010-03-07	1	-24/+2
\| \| \| \| \| \| \| \| \|	These functions are not longer used and can be removed savely. There functionality is now provided by the iommu_{un}map functions which are also capable of multiple page sizes. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu-api: Add ->{un}map callbacks to iommu_ops	Joerg Roedel	2010-03-07	1	-0/+6
\| \| \| \| \| \| \| \| \|	This patch adds new callbacks for mapping and unmapping pages to the iommu_ops structure. These callbacks are aware of page sizes which makes them different to the ->{un}map_range callbacks. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	iommu-api: Add iommu_map and iommu_unmap functions	Joerg Roedel	2010-03-07	1	-0/+31
\| \| \| \| \| \| \| \| \| \| \| \| \|	These two functions provide support for mapping and unmapping physical addresses to io virtual addresses. The difference to the iommu_(un)map_range() is that the new functions take a gfp_order parameter instead of a size. This allows the IOMMU backend implementations to detect easier if a given range can be mapped by larger page sizes. These new functions should replace the old ones in the long term.

*	iommu-api: Rename ->{un}map function pointers to ->{un}map_range	Joerg Roedel	2010-03-07	1	-2/+2
\| \| \| \| \| \| \| \| \|	The new function pointer names match better with the top-level functions of the iommu-api which are using them. Main intention of this change is to make the ->{un}map pointer names free for two new mapping functions. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
*	drivers/base/iommu.c: add missing includes	Andrew Morton	2009-05-07	1	-0/+2
\| \| \| \| \| \| \| \| \| \|	Fix zillions of -mm x86_64 allmodconfig build errors - the file uses EXPORT_SYMBOL() and kmalloc but misses the needed includes.

\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This iommu_op can tell if domain have a specific capability, like snooping control for Intel IOMMU, which can be used by other components of kernel to adjust the behaviour.

*	add frontend implementation for the IOMMU API	Joerg Roedel	2009-01-03	1	-0/+100
	This API can be used by KVM for accessing different types of IOMMUs to do device passthrough to guests. Beside that this API can also be used by device drivers to map non-linear host memory into dma-linear addresses to prevent sgather-gather DMA. UIO may be another user for this API.
