Also, for any patches (not that many) I've done post-Intel: I hereby
give permission to license that code with MIT or compatible license
as the upper bound.
For any code I've produced while at Intel the copyright is owned by
Intel so perhaps Dave could help with that part?
I'm happy if this code ends up to wider use than just kselftest for
sure.
BR, Jarkko
