Please resend your patches using git-send-email so that they can be  
reviewed more easily, and don't forget the Signed-off-by. You should  
cc the ppc maintainers and prefix the subject with target-ppc. A  
longer description and some info on how to test the new code would  
also be nice. Otherwise it looks okay on first sight.

Regards,
Andreas
