It is caused by wrong finding in 2 cross tools for arm. And has been fixed. Thanks. Regarding to the vhost build issue itself, it has gone in latest vhost/linux-next. The cause is the code kbuild captured didn't have patch " vhost: factor out IOTLB " which introduce linux/vhost_iotlb.h at that moment. So just ignore this issue since the missed patch has been added in latest vhost/linux-next.
