Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU changes for v3.4 from Ingo Molnar. 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. * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (48 commits) rcu: Stop spurious warnings from synchronize_sched_expedited rcu: Hold off RCU_FAST_NO_HZ after timer posted rcu: Eliminate softirq-mediated RCU_FAST_NO_HZ idle-entry loop rcu: Add RCU_NONIDLE() for idle-loop RCU read-side critical sections rcu: Allow nesting of rcu_idle_enter() and rcu_idle_exit() rcu: Remove redundant check for rcu_head misalignment PTR_ERR should be called before its argument is cleared. rcu: Convert WARN_ON_ONCE() in rcu_lock_acquire() to lockdep rcu: Trace only after NULL-pointer check rcu: Call out dangers of expedited RCU primitives rcu: Rework detection of use of RCU by offline CPUs lockdep: Add CPU-idle/offline warning to lockdep-RCU splat rcu: No interrupt disabling for rcu_prepare_for_idle() rcu: Move synchronize_sched_expedited() to rcutree.c rcu: Check for illegal use of RCU from offlined CPUs rcu: Update stall-warning documentation rcu: Add CPU-stall capability to rcutorture rcu: Make documentation give more realistic rcutorture duration rcutorture: Permit holding off CPU-hotplug operations during boot rcu: Print scheduling-clock information on RCU CPU stall-warning messages ...
