    Subject[PATCH] mm: slab cache interleave rotor fix
    From: Paul Jackson <pj@sgi.com>
    
    The alien cache rotor in mm/slab.c assumes that the first online
    node is node 0.  Eventually for some archs, especially with hotplug,
    this will no longer be true.
    
    Fix the interleave rotor to handle the general case of node numbering.
