This _looks_ ok to me.  That it fiddles with the PPC MMU handling means
I would like to see the kernel which this lands in actually boot tested
on something which will use that code.  Adam or Ben might have something
they could test it on for us.  That said it is a CVE fix and seems right
to my eye:
