From: Oscar Salvador <osalvador@suse.de>
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()
