Yay!

Entire series pulled in, thanks a lot for the testing and review.

Besides byt psr the big chunk is now polishing the testcase. Iirc I've
written down a detailed description of the task in internal jira and
assigned it to you, right?

I want to have the tests before we enable byt psr to make sure we really
catch all the regressions that might crop up.

Thanks, Daniel
