From 15ca220e1a63af06e000691e4ae1beaba5430c32 Mon Sep 17 00:00:00 2001 From: Chen Gang Date: Wed, 11 Sep 2013 14:20:27 -0700 Subject: [PATCH] mm/page_alloc.c: use '__paginginit' instead of '__init' set_pageblock_order() may be called when memory hotplug, so need use '__paginginit' instead of '__init'. The related warning: The function __meminit .free_area_init_node() references a function __init .set_pageblock_order(). If .set_pageblock_order is only used by .free_area_init_node then annotate .set_pageblock_order with a matching annotation.
