RCU commits for 4.8

Hello, Ingo,

This series contains the following changes:

1. Documentation updates. Just some simple changes, no design-level

	additions.  I guess that means two for the next merge window...

	http://lkml.kernel.org/g/[email protected]

2. Miscellaneous fixes.

	http://lkml.kernel.org/g/[email protected]

3. Torture-test updates.

	http://lkml.kernel.org/g/[email protected]

All of these changes have been subjected to 0day Test Robot and -next testing, and are available in the git repository at:

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git for-mingo
