Martin Schwidefsky 3c1fcfe229 [PATCH] Directed yield: direct yield of spinlocks for s390. ...

Use the new diagnose 0x9c in the spinlock implementation for s390.  It
yields the remaining timeslice of the virtual cpu that tries to acquire a
lock to the virtual cpu that is the current holder of the lock.
