These mostly are for mm init when going through code flow.

Baoquan He (7):
  mm/mm_init.c: remove the useless dma_reserve
  mm/mm_init.c: add new function calc_nr_all_pages()
  mm/mm_init.c: remove meaningless calculation of zone->managed_pages in
    free_area_init_core()
  mm/mm_init.c: remove unneeded calc_memmap_size()
  mm/mm_init.c: remove arch_reserved_kernel_pages()
  mm: move array mem_section init code out of memory_present()
  mm/init: remove the unnecessary special treatment for memory-less node
