From 7b02190c27091f7b4614d9a655981ae20520d22c Mon Sep 17 00:00:00 2001 From: Joonsoo Kim Date: Thu, 5 Feb 2015 12:25:23 -0800 Subject: [PATCH] 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 the old declaration of kernel_map_pages() for some architectures. This patch removes them to fix build failure.
