[IA64] Add Variable Page Size and IA64 Support in Intel IOMMU The patch contains Intel IOMMU IA64 specific code. It defines new machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush function, etc. For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected, dig_vtd is used for machinve vector. Otherwise, kernel falls back to dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off" can be used to force kernel to boot dig machine vector.

swiotlb: replace architecture-specific swiotlb.h with linux/swiotlb.h Impact: cleanup This replaces architecture-specific swiotlb.h (X86 and IA64) with linux/swiotlb.h.
