If max_pfn is not initialized, the various /proc/kpage* files are empty, and selftests/vm/mlock2-tests will fail. max_pfn is also used by the block layer to calculate DMA masks. Switch from init_bootmem_node() to init_bootmem(), as there's only one memory node on Sun-3. This will initialize min_low_pfn and max_low_pfn, which was also not done before.
