>From your patch description, this patch should be broken up.  Moving
the non-architecture specific code out of powerpc should be one patch.
 Additional support should be in another patch.  After each patch, the
code should work properly.

Before posting patches, please review them, making sure
unnecessary/unwanted changes haven't crept in - commenting out code,
moving code without removing the original code.

thanks,
