Thank you for your suggestions. I did change SuperH implementation so
that it uses init_bootmem_node and free_area_init_core. Well, it
works.

But I'm not sure if it's good use or not. At least, it seems that
free_area_init_core is not intended to be used, since it is not
defined in header file.

Things are going like this:

        setu_arch
            call
                init_bootmem_node

        paging_init
          get info. from:
            NODE_DATA(0)->bdata->node_boot_start
            NODE_DATA(0)->bdata->node_low_pfn
          then call
                free_area_init_core (Should I use free_area_init_node instead?)

        mem_init
          get info. from:
            NODE_DATA(0)->bdata->node_boot_start
            NODE_DATA(0)->bdata->node_low_pfn

I think that it would be better if we define macros for START_PFN and
MAX_LOW_PFN, then we could eliminate the variable max_low_pfn even
in the i386 implementation.
