"Mutexes:

- Add killable flavor to guard definitions (Davidlohr Bueso)

- Remove the list_head from struct mutex (Matthew Wilcox)

rwsems:

- Remove the list_head from struct rw_semaphore and
replace it with a single pointer (Matthew Wilcox)

- Fix logic error in rwsem_del_waiter() (Andrei Vagin)

Semaphores:

- Remove the list_head from struct semaphore (Matthew Wilcox)

Jump labels:

Lock context analysis changes and improvements:

- Add context analysis for rwsems (Peter Zijlstra)

- Fix rwlock and spinlock lock context annotations (Bart Van Assche)

- Fix rwlock support in <linux/spinlock_up.h> (Bart Van Assche)

- Add lock context annotations in the spinlock implementation

jump_label: use ATOMIC_INIT() for initialization of .enabled

Currently ATOMIC_INIT() is not used because in the past that macro was
provided by linux/atomic.h which is not usable from linux/jump_label.h.
However since commit 7ca8cf5347f7 ("locking/atomic: Move ATOMIC_INIT
into linux/types.h") the macro only requires linux/types.h.

Remove the now unnecessary workaround and the associated assertions.
