    bitops: Move find_next_bit.o from lib-y to obj-y · bd823821
    Geert Uytterhoeven authored
    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 171d809d ("m68k: merge mmu and
    non-mmu bitops.h"), as m68k had its own inline versions before.
    
    commit 63e424c8 ("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).
