I could not find this commit in the above branch.

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
cd: received redirection to `https://download.01.org/0day-ci/cross-package/' lftpget -c https://download.01.org/0day-ci/cross-package/./gcc-9.3.0-nolibc/x86_64-gcc-9.3.0-nolibc_arm-linux-gnueabihf.tar.xz tar Jxf gcc-9.3.0-nolibc/x86_64-gcc-9.3.0-nolibc_arm-linux-gnueabihf.tar.xz -C /root/0day

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
