* x86/amd-iommu: Use dev->arch->iommu to store iommu related informationJoerg Roedel2009-11-271-1/+1
| | | | | | | | | | This patch changes IOMMU code to use dev->archdata->iommu to store information about the alias device and the domain the device is attached to. This allows the driver to get rid of the amd_iommu_pd_table in the future. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
* Driver Core: Add platform device arch data V3Magnus Damm2009-07-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow architecture specific data in struct platform_device V3. With this patch struct pdev_archdata is added to struct platform_device, similar to struct dev_archdata in found in struct device. Useful for architecture code that needs to keep extra data associated with each platform device. Struct pdev_archdata is different from dev.platform_data, the convention is that dev.platform_data points to driver-specific data. It may or may not be required by the driver. The format of this depends on driver but is the same across architectures. The structure pdev_archdata is a place for architecture specific data. This data is handled by architecture specific code (for example runtime PM), and since it is architecture specific it should _never_ be touched by device driver code. Exactly like struct dev_archdata but for platform devices.

* x86, ia64: convert to use generic dma_map_ops structFUJITA Tomonori2009-01-061-1/+1
| | | | | | | | | | | | | This converts X86 and IA64 to use include/linux/dma-mapping.h. It's a bit large but pretty boring. The major change for X86 is converting 'int dir' to 'enum dma_data_direction dir' in DMA mapping operations. The major changes for IA64 is using map_page and unmap_page instead of map_single and unmap_single.

* x86: Fix ASM_X86__ header guardsH. Peter Anvin2008-10-221-3/+3
| | | | | | | | | Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
