These commits are based on top of the rcu/urgent set sent yesterday. If you would rather rcu/urgent be merged into tip/core/rcu and then this set based on top of that, or some other arrangement, please let me know. git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next There are two more sets of commits queued: o Mathieu's debugobjects changes. These need to be reworked in order to coordinate with other maintainer trees, and also to get the relevant Acked-by:s. This will eventually apply in three stages: (1) add new RCU APIs, (2) apply these APIs into various trees, and (3) remove old RCU APIs. o Arnd's "sparse" checks. These require a quadruple-action approach: (1) add a new RCU API member rcu_dereference_index_check(), (2) a couple of commits must be accepted into maintainer trees (networking, vfs, and mce), (3) a pair of RCU-infrastructure patches, and finally (4) a number of patches to apply __rcu attributes to various trees. Thanx, Paul ------------------> Lai Jiangshan (4) rcu: optionally leave lockdep enabled after RCU lockdep splat rcu: make dead code really dead rcu: move some code from macro to function rcu: ignore offline CPUs in last non-dyntick-idle CPU check Paul E. McKenney (16) rcu: substitute set_need_resched for sending resched IPIs rcu: Fix bogus CONFIG_PROVE_LOCKING in comments to reflect reality. rcu: fix now-bogus rcu_scheduler_active comments. rcu: shrink rcutiny by making synchronize_rcu_bh() be inline rcu: rename rcutiny rcu_ctrlblk to rcu_sched_ctrlblk rcu: refactor RCU's context-switch handling rcu: slim down rcutiny by removing rcu_scheduler_active and friends rcu: enable CPU_STALL_VERBOSE by default rcu: disable CPU stall warnings upon panic rcu: print boot-time console messages if RCU configs out of ordinary rcu: improve RCU CPU stall-warning messages rcu: permit discontiguous cpu_possible_mask CPU numbering rcu: reduce the number of spurious RCU_SOFTIRQ invocations rcu: improve the RCU CPU-stall warning documentation rcu: make SRCU usable in modules rcu: RCU_FAST_NO_HZ must check RCU dyntick state
