atomic: fix atomic_long_cmpxchg/xchg for 64 bit architectures
On a linux-next allyesconfig build:
kernel/trace/ring_buffer.c:1726:
warning: passing argument 1 of 'atomic_cmpxchg' from incompatible pointer type
linux-next/arch/s390/include/asm/atomic.h:112:
note: expected 'struct atomic_t *' but argument is of type 'struct atomic64_t *'
atomic_long_cmpxchg and atomic_long_xchg are incorrectly defined for 64
bit architectures. They should be mapped to the atomic64_* variants.
