git format-patch -v6 -4
git send-email v6*

You keep sending them as separate emails thus no proper threading.

Hm, you are right, it passes the checks. There must be a bug in dtschema

There is no problem running it on x86 system. We all run it there. Just
install basic cross compiler. Every distro has it...
