Tina Zhang c834b038c2 devices: virtio: iommu: get iova_max_addr according to ranges' info ... Previously the iova_max_addr was got according to the cpu physical address size. Since the cpu physical address is no more than the maximum iova size provided by hardware iommu, the iova space size can work for any passthrough devices. But it may not utilize the whole iova space, as the iova size isn't got from the underlying hardware iommu. This patch introduces a way to get iova_max_addr according to the iommu ranges' info, therefore the iova_max_addr can be precisely calculated.
