On PHB3, PCI devices can bypass IOMMU for DMA access. If we pass through one PCI device, whose hose driver ever enable the bypass mode, pdev->dev.archdata.dma_data.iommu_table_base isn't IOMMU table. However, EEH needs access the IOMMU table when the device is owned by guest. The patch fixes pdev->dev.archdata.dma_data.iommu_table when passing through the device to guest in pnv_pci_ioda2_set_bypass().
