Merge tag 'rcu.release.v7.2' of gitolite.kernel.org:pub/scm/linux/kernel/git/rcu/linux

Pull RCU updates from Uladzislau Rezki:
 "Torture test updates:

   - Improve kvm-series.sh script by adding examples in its header
     comment

   - Lazy RCU is more fully tested now by replacing call_rcu_hurry()
     with call_rcu() and doing rcu_barrier() to motivate lazy callbacks
     during a stutter pause

   - Add more synonyms for the "--do-normal" group of torture.sh
     command-line arguments

  Misc changes:

   - Reduce stack usage of nocb_gp_wait() to address frame size warning
     when built with CONFIG_UBSAN_ALIGNMENT

   - The synchronize_rcu() call can detect the flood and latches a
     normal/default path temporary switching to wait_rcu_gp() path

   - Document using rcu_access_pointer() to fetch the old pointer for
     lockless cmpxchg() updates

   - Simplify some RCU code using clamp_val()

   - Fix a kerneldoc header comment typo in srcu_down_read_fast()"
