From bd823821e68e5de6d680cbbf1c8654c9c36674e1 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 30 Aug 2011 15:17:03 +0200 Subject: [PATCH] bitops: Move find_next_bit.o from lib-y to obj-y If there are no builtin users of find_next_bit_le() and find_next_zero_bit_le(), these functions are not present in the kernel image, causing m68k allmodconfig to fail with: ERROR: "find_next_zero_bit_le" [fs/ufs/ufs.ko] undefined! ERROR: "find_next_bit_le" [fs/udf/udf.ko] undefined! ... This started to happen after commit 171d809df189 ("m68k: merge mmu and non-mmu bitops.h"), as m68k had its own inline versions before. commit 63e424c84429 ("arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT, BIT_LE, LAST_BIT}") added find_last_bit.o to obj-y (so it's always included), but find_next_bit.o to lib-y (so it gets removed by the linker if there are no builtin users).
