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

I can hardly believe it can't work.

I get

# file include/linux/vringh.h
include/linux/vringh.h: C source, ASCII text

So this looks like a false positive to me?

Thanks

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.
