    Subject[PATCH v6 0/5] Refactor free_area_init_core and add free_area_init_core_hotplug
    Date
    From: Oscar Salvador <osalvador@suse.de>

    Changes:

    v5 -> v6:
    - Added patch from Pavel that removes __paginginit
    - Convert all __meminit(old __paginginit) to __init
    for functions we do not need after initialization.
    - Move definition of free_area_init_core_hotplug
    to include/linux/memory_hotplug.h
    - Add Acked-by from Michal Hocko

    v4 -> v5:
    - Remove __ref from hotadd_new_pgdat and placed it to
    free_area_init_core_hotplug. (Suggested by Pavel)
    - Since free_area_init_core_hotplug is now allowed to be in a different
    section (__ref), remove the __paginginit.)
    - Stylecode in free_area_init_core_hotplug (Suggested by Pavel)
    - Replace s/@__paginginit/@__init for free_area_init_node/free_area_init_core
    as these functions are now only called during early init.
    - Add Reviewd-by from Pavel

    v3 -> v4:
    - Unify patch-5 and patch-4.
    - Make free_area_init_core __init (Suggested by Michal).
    - Make zone_init_internals __paginginit (Suggested by Pavel).
    - Add Reviewed-by/Acked-by:

    v2 -> v3:
    - Think better about split free_area_init_core for
    memhotplug/early init context (Suggested by Michal).

    This patchset does the following things:

    1) Clean up/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:
    4) Remove __paginginit and convert it to __meminit
    5) Reconvert all __meminit to __init for functions we do not need after
    initialization.

    After this, we have:

    free_area_init_core: called during early initialization
    free_area_init_core_hotplug: called whenever a new node is allocated/re-used (memhotplug path)

    Oscar Salvador (3):
    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: Introduce free_area_init_core_hotplug

    Pavel Tatashin (2):
    mm: access zone->node via zone_to_nid() and zone_set_nid()
    mm: remove __paginginit
