    [PATCH] fix up physnode_map · 40fd17bc
    Martin J. Bligh authored
    At the moment, we initialise physnode_map from the various BIOS tables,
    which can create problems, as holes inside an node return 1 for pfn_valid,
    and yet pfn_to_nid is not correct for them.  I'd hacked around this in my
    tree by defaulting the mapping to 0, not -1, but that's not the correct fix
    ...  this is.
    
    I consolidated all the code back into 1 place, and use node_start_pfn[] and
    node_end_pfn[] to walk over it instead - that means it matches up perfectly
    with lmem_map's as we're using the same data.  It also cleans up a lot of
    the code.
    
    Tested on both NUMA-Q and x440 ...  and it only affects i386 NUMA boxen.
