Linus Torvalds 8d99084efc A couple of locking fixes: 
- Fix incorrect failure injection handling on the fuxtex code
 
  - Prevent a preemption warning in lockdep when tracking local_irq_enable()
    and interrupts are already enabled
 
  - Remove more raw_cpu_read() usage from lockdep which causes state
    corruption on !X86 architectures.
 
  - Make the nr_unused_locks accounting in lockdep correct again.
