This patch is in linux-next and its build is failing from quite some time:
https://storage.staging.kernelci.org/kernelci/staging-next/staging-next-20220301.0/x86_64/x86_64_defconfig+x86-chromebook+kselftest/gcc-10/logs/kselftest.log

I'm not sure in which tree selftests/interpreter is present. It was sent
here:
https://lore.kernel.org/lkml/20220104155024.48023-5-mic@digikod.net/

How can I find the tree from which this patch is coming?

I forgot to add the tag:
