    lib/checksum.c: make do_csum optional · 217a8c7b
    Arnd Bergmann authored
    Mike Frysinger suggested that do_csum should be optional
    so that an architecture can use the generic checksum code
    but still provide an optimized fast-path for the most
    critical function.
    
    This can mean an implementation using inline assembly,
    or in case of Alpha one using 64-bit arithmetic in C.
