From: Oscar Salvador <osalvador@xxxxxxx>
Changes:
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 three 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:
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 (1):
mm: access zone->node via zone_to_nid() and zone_set_nid()
