Try to use commit dc3b0673ae5efb73edab66ec5c2f074272e9a4df.
But this command does not work (I remember it used to work):
# GCC_VERSION=9.3.0 make.cross ARCH=arm

Hi Jason, thanks for report this issue. 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.
Good to know this.
Thanks for the updating.
