arch/powerpc/mm/slice.c:704:5: error: expected identifier or ‘(’ before numeric

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 1217d34b531c76362217057ca70a8ce8950574e0
"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
