SYNOPSIS
       void get_pfn_range_for_nid(unsigned int nid, unsigned long * start_pfn,
                                  unsigned long * end_pfn);

ARGUMENTS
       nid
           The nid to return the range for. If MAX_NUMNODES, the min and max PFN are returned.

       start_pfn
           Passed by reference. On return, it will have the node start_pfn.

       end_pfn
           Passed by reference. On return, it will have the node end_pfn.
