mm/page_alloc.c: drop uneeded __meminit and __meminitdata
Since commit 03e85f9d5f1 ("mm/page_alloc: Introduce free_area_init_core_hotplug"), some functions changed to only be called during system initialization. Concretly, free_area_init_node() and the functions that hang from it. Also, some variables are no longer used after the system has gone through initialization. So this could be considered as a late clean-up for that patch. This patch changes the functions from __meminit to __init, and the variables from __meminitdata to __initdata. In return, we get some KBs back: Before: Freeing unused kernel image memory: 2472K After: Freeing unused kernel image memory: 2480K Link: http://lkml.kernel.org/r/20181204111507.4808-1-osalvador@suse.de Signed-off-by: Oscar Salvador <osalvador@suse.de> Reviewed-by: Wei Yang <richard.weiyang@gmail.com> Cc: Michal Hocko <mhocko@suse.com> Cc: Pavel Tatashin <pavel.tatashin@microsoft.com> Cc: Vlastimil Babka <vbabka@suse.cz> Cc: Alexander Duyck <alexander.h.duyck@linux.intel.com> Cc: David Hildenbrand <david@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
