sparc32: Kill btfixup for xchg()'s 'swap' instruction.
We always have this instruction available, so no need to use btfixup for it any more. This also eradicates the whole of atomic_32.S and thus the __atomic_begin and __atomic_end symbols completely. Signed-off-by: David S. Miller <davem@davemloft.net>
