I'm still completely confused as to the base of this patchset.  The
first patch has the following hunk for arch/x86/include/asm/paravirt.h:


--- arch/x86/include/asm/paravirt.h
+++ arch/x86/include/asm/paravirt.h
@@ -718,7 +718,7 @@
        PVOP_VCALLEE2(pv_lock_ops.lock_spinning, lock, ticket);
 }

-static __always_inline void ____ticket_unlock_kick(struct arch_spinlock
*lock,
+static __always_inline void __ticket_unlock_kick(struct arch_spinlock
*lock,
                                                        __ticket_t ticket)
 {
        PVOP_VCALL2(pv_lock_ops.unlock_kick, lock, ticket);


However, there is no ticket_unlock_kick in paravirt.h in either
tip:master nor in linus...
