x86 calgary: fix handling of devices that aren't behind the Calgary The calgary code can give drivers addresses above 4GB which is very bad for hardware that is only 32bit DMA addressable. With this patch, the calgary code sets the global dma_ops to swiotlb or nommu properly, and the dma_ops of devices behind the Calgary/CalIOC2 to calgary_dma_ops. So the calgary code can handle devices safely that aren't behind the Calgary/CalIOC2.

x86: clean up iommu.h and gart.h This remove lots of duplications in iommu.h and gart.h. The end result of this patch is: - iommu.h is a header file for everyone related with IOMMUs. - gart.h is the private header file. Only pci-gart_64.c and its friends include it.

intel-iommu: IA64 support The current Intel IOMMU code assumes that both host page size and Intel IOMMU page size are 4KiB. The first patch supports variable page size. This provides support for IA64 which has multiple page sizes. This patch also adds some other code hooks for IA64 platform including DMAR_OPERATION_TIMEOUT definition.
