Sparc32 already supported it, as a consequence of using the generic atomic64 implementation. And the sparc64 implementation is rather trivial. This allows us to set ARCH_HAS_ATOMIC64_DEC_IF_POSITIVE for all of sparc, and avoid the annoying warning from lib/atomic64_test.c Signed-off-by: David S. Miller <davem@davemloft.net>
