This patch does following things: - Flush iotlb in iommu_page_mapping() after page mapping - Change BUG_ON() to ASSERT() in iommu_flush_iotlb_psi() - Add iommu_flush_write_buffer() if iommu_flush_iotlb_psi() fails in dma_pte_clear_one() - Change panic() message to easily know where panic happens Signed-off-by: Weidong Han <weidong.han@xxxxxxxxx>
