Thanks for rebasing, Tamir, I appreciate it.

This has a bunch of hits in configfs, cpufreq and Nova [1]. I guess
you built without those enabled.

Could you please fix those? Since this affects other maintainers that
we need to ask the Acked-by to, let's try to at least give them the
final state.

Thanks!

Cheers,
Miguel
