The definition of atomic_dec_if_positive() assumes that atomic_sub_if_positive() exists, which is only the case if metag specific atomics are used. This results in the following build error when trying to build metag1_defconfig. kernel/ucount.c: In function 'dec_ucount': kernel/ucount.c:211: error: implicit declaration of function 'atomic_sub_if_positive' Moving the definition of atomic_dec_if_positive() into the metag conditional code fixes the problem.
