    mm: use two zonelist that are filtered by GFP mask
    
    Currently a node has two sets of zonelists, one for each zone type in the
    system and a second set for GFP_THISNODE allocations.  Based on the zones
    allowed by a gfp mask, one of these zonelists is selected.  All of these
    zonelists consume memory and occupy cache lines.
    
    This patch replaces the multiple zonelists per-node with two zonelists.  The
    first contains all populated zones in the system, ordered by distance, for
    fallback allocations when the target/preferred node has no free pages.  The
    second contains all populated zones in the node suitable for GFP_THISNODE
    allocations.
    
    An iterator macro is introduced called for_each_zone_zonelist() that interat
    through each zone allowed by the GFP flags in the selected zonelist.
