Oleg Nesterov cc5f730b41 locking/percpu-rwsem: Clean up the lockdep annotations in percpu_down_read() 
Based on Peter Zijlstra's earlier patch.

Change percpu_down_read() to use __down_read(), this way we can
do rwsem_acquire_read() unconditionally at the start to make this
code more symmetric and clean.
