My plan in this area is:
- Get my dev box operational again (awaiting spare parts from Intel)
- Get usual configs warning free (or almost warning free)
- Enable the warning in kbuild-next.git right after -rc1

As my dev box is down atm I have prioritized what I conviniently
can do on my mail-box (no defconfig/all*config builds).
