Yeah, good point - I distilled that list in the merge commit 
itself (see commit bdd4431c8d071491a68a65d9457996f222b5ecd3) - 
should have exported that to the pull request itself:

Subject: [PATCH] Merge branch 'rcu/next' of
 git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu

The major features of this series are:

 - making RCU more aggressive about entering dyntick-idle mode in order to
   improve energy efficiency

 - converting a few more call_rcu()s to kfree_rcu()s

 - applying a number of rcutree fixes and cleanups to rcutiny

 - removing CONFIG_SMP #ifdefs from treercu

 - allowing RCU CPU stall times to be set via sysfs

 - adding CPU-stall capability to rcutorture

 - adding more RCU-abuse diagnostics

 - updating documentation

 - fixing yet more issues located by the still-ongoing top-to-bottom
   inspection of RCU, this time with a special focus on the
   CPU-hotplug code path.

Thanks,

	Ingo
