Update.
* sysdeps/unix/sysv/linux/x86_64/lowlevellock.h
(__lll_mutex_lock_wait): Reverse order of first two parameters.
(__lll_mutex_timedlock_wait): Likewise.
(lll_mutex_lock): Adjust asm for that.
(lll_mutex_timedlock): Likewise. Mark cx, cc, r10 as clobbered.
(lll_lock): Adjust asm for operand order change.
* sysdeps/unix/sysv/linux/x86_64/lowlevelmutex.S: New file.
* sysdeps/unix/sysv/linux/x86_64/libc-lowlevelmutex.S: New file.
