With virtio 1, the vring layout is split in 3 separate regions of contiguous memory for the descriptor table, the available ring and the used ring, as opposed with legacy virtio which uses a single region. In case of memory re-mapping, the code ensures it doesn't affect the vring mapping. This is done in vhost_verify_ring_mappings() which assumes the device is legacy. This patch changes vhost_verify_ring_mappings() to check the mappings of each part of the vring separately. This works for legacy mappings as well.
