Max, I think you are right that in an earlier attempt to support cache
aliasing, we tried to allocate pages with the correct 'color', and
cached pages locally (if I remember correctly). The approach we use now
doesn't require that so the suggested patches are fine. (Note that cache
aliasing support hasn't been committed to mainline yet)

Thanks,
