Zide Chen 2f19cf0d95 devices: get all possible host IOMMU device supported page sizes ... page_size_mask in IOMMU device configuration contains the bitmask of all page sizes that can be mapped. It's good to get this information from host VFIO/IOMMU driver, so that the guest is able to issue DMA mapping requests with page size as large as possible to reduce the number of DMA map requests.
