[PATCH] vhost: Add vhost_commit callback for SeaBIOS ROM region re-mapping
...Nicholas Bellinger <nab at linux-iscsi.org> This patch follows MST's recommendation to move checks for vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations from MemoryListener->region_[add,del]() -> vhost_set_memory() into final MemoryListener->commit() -> vhost_commit() callback. It addresses the case where virtio-scsi vq ioport RAM re-mapping to read-only SeaBIOS ROM triggers a cpu_physical_memory_map() NIL MemoryRegionSection pointer failure. Also save vhost_dev->mem_changed_[start,end]_addr values in vhost_set_memory() for final ranges_overlap checks. (...
