Log message:
        For RM9000, R10000, R12000 change prefetch mode for the destination
        range of clear_page and copy_page from StoreRetained to StoreStreamed.
        This shaves of a few seconds of a kernel build.  For now all other
        platforms that have a usable prefetch instruction continue to use
        PrepareForStore; some further performance analysis is needed to
        pick the best performing type of hint for those.
        
        In general we assume a very low hit rate on pages cleared with
        clear_page, so a way to do something like caching mode Store
        Accelerated would be very interesting - but mixing cache modes has
        other issues ...
