You didn't introduce it but do you know what the code is trying to do
here?

        byte_length = word_length * 4;

        if (byte_length % 4)
                aligncnt = 4 - (byte_length % 4);
        else
                aligncnt = 0;
        byte_length += aligncnt;

        if (byte_length && ((byte_length % 64) == 0))
                byte_length += 4;

        if (byte_length < 64)
                byte_length = 68;


Apparently the stuff has to be aligned to 4 bytes, but it can't be
aligned at 64 bytes and it can't be less than 68 bytes long.  The 
part that especially confuses me is why it can't be aligned at 64 bytes.

regards,
dan carpenter
