Now that looks pretty good.

But I asked for that being a separate patch with a separate changelog. And
the intel_cache_info() change wants to be in a separate patch as well. Then
the third patch is the one which makes use of these changes for
centaur.

Please read review comments carefully and rather ask when you have doubts
about the meaning.
