    If you need a quad only copy then put it into asm/string.h (asm/io.h if
    its operating on I/O space I guess) or somewhere similar as a generic
    function that does just that. That allows people to come along and
    provide the same functions for other platforms if they need it, and also
    makes it possible for others to use this feature if their hardware has
    the same feature.
    
    Nobody expects you as a vendor to support it on sparc64, x86-32 or
    whatever, nor to write sparc64 asm functions just to make it possible
    for someone to do so cleanly later on.
