Linus Torvalds 652fa53caa Three small fixes/updates for the locking core code:
- Plug a task struct reference leak in the percpu rswem implementation.
 
  - Document the refcount interaction with PID_MAX_LIMIT
 
  - Improve the 'invalid wait context' data dump in lockdep so it contains
    all information which is required to decode the problem
