From 973f7c390d6f50083d1106c7e9e7213b5846863b Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 21 Oct 2014 14:25:38 +1100 Subject: [PATCH] powerpc/mm: Fix build error with hugetlfs disabled MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit arch/powerpc/mm/slice.c:704:5: error: expected identifier or ‘(’ before numeric constant int is_hugepage_only_range(struct mm_struct *mm, unsigned long addr, ^ make[1]: *** [arch/powerpc/mm/slice.o] Error 1 make: *** [arch/powerpc/mm/slice.o] Error 2 This got introduced via 378fcd1ac48da9a29c93366f8aa13c01db1b1eeb "powerpc: Ensure global functions include their prototype". We started including linux/hugetlb.h with that patch and now we have #define is_hugepage_only_range(mm, addr, len) 0 with hugetlbfs disabled.
