Subject: [PATCH 2/2] mm: fix undefined reference to `.kernel_map_pages' on PPC builds
Date: Tue, 20 Jan 2015 14:02:00 -0600 [thread overview]
Message-ID: <20150120140200.aa7ba0eb28d95e456972e178@freescale.com> (raw)
It's possible to configure DEBUG_PAGEALLOC without PAGE_POISONING on
ppc. Fix building the generic kernel_map_pages() implementation in
this case:
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
