This series supports DMA device to use vfio in async vhost. The first patch extends the capability of current vfio dma mapping API to allow partial unmapping for adjacent memory if the platform does not support partial unmapping. The second patch involves the IOMMU programming for guest memory in async vhost. v5: * Fix issue of a pointer be freed early. v4: * Fix a format issue. v3: * Move the async_map_status flag to virtio_net structure to avoid ABI breaking. v2: * Add rte_errno filtering for some devices bound in the kernel driver. * Add a flag to check the status of region mapping. * Fix one typo.
