    Dave, look, he says we will oops when sendfiling the last byte of a page,
    and will have to call skb_checksum().

    It is true. But his patch must be rewritten, bswap is forbidden
    on older processors.

    Better fix is to verify len >=2 before half-word alignment
    test at the beginning of csum_partial. I am not enough of
    an x86 coder to hack this up reliably. :-)
