Provides an easy way to loop over all non-abstract CPU classes.
Signed-off-by: Andreas Färber<afaer...@suse.de>
I have a patch in my next series which provides an interface for this.
https://github.com/aliguori/qemu/commit/42ab3f78477307438591c77816f06f12cf9d9fc0
I'll post a proper version tomorrow.
Regards,
Anthony Liguori
