Subject: [PATCH v3 0/5] Refactor free_area_init_core and add free_area_init_core_hotplug

From: Oscar Salvador <osalvador@...e.de>

This patchset does three things:

 1) Clean ups/refactor free_area_init_core/free_area_init_node
    by moving the ifdefery out of the functions.
 2) Move the pgdat/zone initialization in free_area_init_core to its
    own function.
 3) Introduce free_area_init_core_hotplug, a small subset of free_area_init_core,
    which is only called from memhotlug code path.
    In this way, we have:

    free_area_init_core: called during early initialization
    free_area_init_core_hotplug: called whenever a new node was allocated (memhotplug path)

Oscar Salvador (4):
  mm/page_alloc: Move ifdefery out of free_area_init_core
  mm/page_alloc: Inline function to handle
    CONFIG_DEFERRED_STRUCT_PAGE_INIT
  mm/page_alloc: Move initialization of node and zones to an own
    function
  mm/page_alloc: Introduce memhotplug version of free_area_init_core

Pavel Tatashin (1):
  mm: access zone->node via zone_to_nid() and zone_set_nid()
