Is this a new warning in the sense that the string is different now? Or
you never got it before on sparc64. I don't have a sparc toolchain at
hand now but it looks to me like atomic64_test.c should have given the
warning before this patch as atomic64_dec_if_positive() does not seem to
be defined on sparc64.

Thanks.
