Hello!

This series provides miscellaneous fixes:

	serendipity, courtesy of Neeraj Upadhyay.

	courtesy of Neeraj Upadhyay.

3.	Make kfree_rcu() ignore NULL pointers.

4.	Set a maximum limit for back-to-back callback invocation.

5.	Remove ".vnet" from paulmck email addresses.

6.	Upgrade sync_exp_work_done() to smp_mb().

8.	Force inlining of rcu_read_lock(), courtesy of Waiman Long.

9.	Don't return a value from rcu_assign_pointer(), courtesy of
	Andrea Parri.
