Thank you very much for the series. This work has been scheduled in my
TODO list for years. I could have done it earlier but a simple at the
first glance change turned to be tricky. The main concern was the
stage at what CM was probed. I was afraid to break things by changing
the order of the CM-base address getting. Let's discuss this matter in
the respective patch. It might get to be I was wrong to worry.
