Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull the RCU tree from Paul E. McKenney: "The major features of this series are: 1. Preventing latency spikes of more than 200 microseconds for kernels built with NR_CPUS=4096, which is reportedly becoming the default for some distros. This is a first step, as it does not help with systems that actually -have- 4096 CPUs (work on this case is in progress, but is not yet ready for mainline). This category also includes improving concurrency of rcu_barrier(), placed here due to conflicts. Posted to LKML at: https://lkml.org/lkml/2012/6/22/381. Note that patches 18-22 of that series have been defered to 3.7, as they have not yet proven themselves to be mainline-ready (and yes, these are the ones intended to get rid of RCU's latency spikes for systems that actually have 4096 CPUs). 2. Updates to documentation and rcutorture fixes, the latter category including improvements to rcu_barrier() testing. Posted to LKML at: http://lkml.indiana.edu/hypermail/linux/kernel/1206.1/04094.html. 3. Miscellaneous fixes posted to LKML at: https://lkml.org/lkml/2012/6/22/500, with the exception of the last commit, which was posted here: http://www.gossamer-threads.com/lists/linux/kernel/1561830 4. RCU_FAST_NO_HZ fixes and improvements. Posted to LKML at: http://lkml.indiana.edu/hypermail/linux/kernel/1206.1/00006.html and http://www.gossamer-threads.com/lists/linux/kernel/1561833. The first four patches of the first series went into 3.5 to fix a regression. 5. Code-style fixes. These were posted to LKML at http://lkml.indiana.edu/hypermail/linux/kernel/1205.2/01180.html and http://lkml.indiana.edu/hypermail/linux/kernel/1205.2/01181.html.
