Linus,

Please pull the latest core-rcu-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git core-rcu-for-linus

# HEAD: 73a7ac2808fa52bdab1781646568b6f90c3d7034 Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu

The main RCU changes in this cycle are:

* Add RCU torture scripts/tooling.

* Static analysis improvements.

* Update RCU documentation.

* Miscellaneous fixes.

Thanks,

Ingo
