    Recently noticed that __GFP_HIGHIO has played no real part since bounce
    buffering was converted to mempool in 2.5.12: so this patch (over 2.5.58-mm1)
    removes it and GFP_NOHIGHIO and SLAB_NOHIGHIO.
    
    Also removes GFP_KSWAPD, in 2.5 same as GFP_KERNEL; leaves GFP_USER, which
    can be a useful comment, even though in 2.5 same as GFP_KERNEL.
    
    One anomaly needs comment: strictly, if there's no __GFP_HIGHIO, then
    GFP_NOHIGHIO translates to GFP_NOFS; but GFP_NOFS looks wrong in the block
    layer, and if you follow them down, you find that GFP_NOFS and GFP_NOIO
    behave the same way in mempool_alloc - so I've used the less surprising
    GFP_NOIO to replace GFP_NOHIGHIO.
