	Add comment.
	(atomic_decrement_and_test): Add comment.

	* include/atomic.h (atomic_compare_and_exchange_val_acq): Add comment.
	Don't define if __arch_compare_and_exchange_val_32_acq is not defined.
	(atomic_compare_and_exchange_bool_acq): Add comment.  Don't use
	__oldval variable in the macro, since it might be macro argument.
	(atomic_decrement_if_positive): Initialize __memp, remove setting
	of non-existent variable.
	(atomic_bit_test_set): Cast 1 to __typeof (*mem) before shifting.
	* sysdeps/ia64/bits/atomic.h (atomic_exchange_and_add): Implement
	using atomic_compare_and_exchange_val_acq.
	(atomic_decrement_if_positive, atomic_bit_test_set): Define.
	* sysdeps/s390/bits/atomic.h (__arch_compare_and_exchange_val_8_acq):
	Renamed from...
	(__arch_compare_and_exchange_bool_8_acq): ... this.
	(__arch_compare_and_exchange_val_16_acq): Renamed from...
	(__arch_compare_and_exchange_bool_16_acq): ... this.
	(__arch_compare_and_exchange_val_32_acq): Return old value.  Renamed
	from...
	(__arch_compare_and_exchange_bool_32_acq): ... this.
	(__arch_compare_and_exchange_val_64_acq): Return old value.  Renamed
	from...
	(__arch_compare_and_exchange_bool_64_acq): ... this.
	(__arch_compare_and_exchange_val_32_acq): Use __typeof for local
	variables types instead of assuming int.
	Change prefix of local variables to __arch.
	* sysdeps/generic/bits/atomic.h (arch_compare_and_exchange_acq):
	Remove.
	(atomic_compare_and_exchange_val_acq,
	atomic_compare_and_exchange_bool_acq): Define.

	* csu/tst-atomic.c: New test.
	* csu/tst-atomic-long.c: New test.
	* csu/Makefile (tests): Add tst-atomic and tst-atomic-long.

	* malloc/memusagestat.c (main): Kill warning if uint64_t is ulong.

	* sysdeps/s390/Versions: Add trailing newline.

	* sysdeps/unix/sysv/linux/sysconf.c (__sysconf): Kill warning
	if INTERNAL_SYSCALL_ERROR_P doesn't use its first argument.
