    [PATCH] x86_64: Handle empty node zero · 0d015324

    It is possible to boot a Unisys ES7000 with CPUs from multiple cells, and not
    also include the memory from those cells.  This can create a scenario where
    node 0 has cpus, but no associated memory.  The system will boot fine in a
    configuration where node 0 has memory, but nodes 2 and 3 do not.
    
    [AK: I rechecked the code and generic code seems to indeed handle that already.
    Dan's original patch had a change for mm/slab.c that seems to be already in now.]
