In kvm_iommu_map_pages(), we need to know the page size via call kvm_host_page_size(). And it will check whether the target slot is valid before return the right page size. Currently, we will map the iommu pages when creating a new slot. But we call kvm_iommu_map_pages() during preparing the new slot. At that time, the new slot is not visible by domain(still in preparing). So we cannot get the right page size from kvm_host_page_size() and this will break the IOMMU super page logic. The solution is to map the iommu pages after we insert the new slot into domain.
