The patche set (Intel IOMMU generic patch and ia64 specific patch) together enable Intel IOMMU on IA64 platform. They are applied cleanly on the latest linux-next tree which contains Intel IOMMU interrupt remapping and VT-d driver KVM support code.
 
If applying only the generic patch on x86-64 kernel, x86-64 IOMMU is working fine, i.e. the generic patch doesn't have compilation and functionality impact on x86-64 IOMMU. If applying only the ia64 specific patch on ia64 kernel, ia64 is working as non-IOMMU/swiotlb case. If applying both of the patches and set CONFIG_DMAR=y, ia64 IOMMU is working.
 
Thanks.
