    change to:
    .map_pages = intel_iommu_map_pages,
    .unmap_pages = intel_iommu_unmap_pages,

    > + .iova_to_phys = intel_iova_to_phys,

    should remove old kvm VT-d API declarations in include/linux/intel-iommu.h, and don't export them. In fact, should remove old kvm VT-d APIs, and move their code to corresponding new APIs. I can help you to do this if need.

    Regards,
    Weidong
