From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>
Subject: mm/debug_pagealloc: fix build failure on ppc and some other archs
Kim Phillips reported following build failure.
LD init/built-in.o
mm/built-in.o: In function `free_pages_prepare':
mm/page_alloc.c:770: undefined reference to `.kernel_map_pages'
mm/built-in.o: In function `prep_new_page':
mm/page_alloc.c:933: undefined reference to `.kernel_map_pages'
mm/built-in.o: In function `map_pages':
mm/compaction.c:61: undefined reference to `.kernel_map_pages'
make: *** [vmlinux] Error 1
Reason for this problem is that commit 031bc5743f15 ("mm/debug-pagealloc:
make debug-pagealloc boottime configurable") forgot to remove old
declaration of kernel_map_pages() in some architectures. This patch
removes them to fix build failure.
