Pull locking updates from Ingo Molnar:
- Disable preemption in rwsem_write_trylock()'s attempt to take the
rwsem, to avoid RT tasks hogging the CPU, which managed to preempt
this function after the owner has been cleared but before a new owner
is set. Also add debug checks to enforce this.
- Add __lockfunc to more slow path functions and add __sched to
semaphore functions.
- Mark spinlock APIs noinline when the respective CONFIG_INLINE_SPIN_*
toggles are disabled, to reduce LTO text size.
- Print more debug information when lockdep gets confused in
look_up_lock_class().
- Improve header file abuse checks.
- Misc cleanups
