glibc/nptl/sysdeps/unix/sysv/linux/i386/i486/libc-lowlevellock.S
Ulrich Drepper 9356d063df Update.
* sysdeps/unix/sysv/linux/i386/i486/lowlevellock.S: Don't define
	LOCK is already defined.  Don't define lll_unlock_wake_cb and
	__lll_timedwait_tid for libc.so.
	* sysdeps/unix/sysv/linux/i386/i486/libc-lowlevellock.S: Only
	define LOCK here (if UP is not defined).  The actual code is in
	lowlevellock.S.
