	* sysdeps/unix/sysv/linux/sparc/sparc64/get_clockfreq.c
	(set_obp_int): New function.
	(get_obp_int): New function.
	(__get_clockfreq_via_dev_openprom): Likewise.
	* sysdeps/unix/sysv/linux/sparc/sysdep.h (INTERNAL_SYSCALL_ERROR_P): Avoid
	unused variable warnings on 'val' and use builtin_expect.
	(INLINE_SYSCALL): Don't wrap INTERNAL_SYSCALL_ERROR_P with builtin_expect.
	(INLINE_CLONE_SYSCALL): Likewise.

	* sysdeps/unix/sysv/linux/sparc/sem_post.c (__new_sem_post): Use
	atomic_increment and remove unused local variable.
	(__old_sem_post): Likewise.
