This patch is just as broken as the PReP one...

The patch contradicts your description. Did you diff the wrong way?!

This patch conflicts with our ongoing CPU definition refactoring:
http://lists.nongnu.org/archive/html/qemu-devel/2013-02/msg01672.html
We are extracting some of the definitions into an alias list and as a
follow-up preparing to use QOM for CPU model -> CPU type relationships.
It may need to be delayed to apply on top.

Andreas
