Hi Andrew, After merging the akpm-current tree, today's linux-next build (powerpc ppc64_defconfig) produced this warning:
mm/hugetlb.c:1166:21: warning: 'alloc_gigantic_page' defined but not used [-Wunused-function] static struct page *alloc_gigantic_page(int nid, unsigned int order) ^ Introduced by commit 4acc8ccc3c57 ("mm/hugetlb.c: rename some allocation functions") -- Cheers, Stephen Rothwell
