    Umm:
    - it's not so much slowness as code expansion (NIPQUAD is only used by
    various printk's, so performance per se is secondary)
    - a well-written htonl() macro will not do just the stupid expansion of
    shifts, it will use inline assembly to generate a "bswap" instruction.
    - gcc isn't that clever.
