[PATCH RFC tip/core/rcu 06/10] rcu: fix now-bogus rcu_scheduler_active comments.
The rcu_scheduler_active check has been wrapped into the new debug_lockdep_rcu_enabled() function, so update the comments to reflect this new reality. Signed-off-by: Paul E.

[PATCH RFC tip/core/rcu 07/10] rcu: shrink rcutiny by making synchronize_rcu_bh() be inline
Because synchronize_rcu_bh() is identical to synchronize_sched(), make the former a static inline invoking the latter, saving the overhead of an EXPORT_SYMBOL_GPL() and the duplicate code.

[PATCH RFC tip/core/rcu 03/10] rcu: move some code from macro to function
From: Lai Jiangshan <laijs(a)cn.fujitsu.com> Shrink the RCU_INIT_FLAVOR() macro by moving all but the initialization of the ->rda[] array to rcu_init_one(). The call to rcu_init_one() can then be moved to the end of the RCU_INIT_FLAVOR() macro, which is required because rcu_boot_init_percpu_data(), which is now ca... 5 Apr 2010 14:59

Hello! RFC preview of RCU patches queued for 2.6.35: 1. substitute set_need_resched for sending resched IPIs This reduces OS jitter. 2. make dead code really dead 3. move some code from macro to function Cleanups from Lai Jiangshan. 4. ignore offline CPUs in last non dyntick idle CPU check Fix... 5 Apr 2010 14:59

[PATCH RFC tip/core/rcu 01/10] rcu: substitute set_need_resched for sending resched IPIs
This patch adds a check to __rcu_pending() that does a local set_need_resched() if the current CPU is holding up the current grace period and if force_quiescent_state() will be called soon. The goal is to reduce the probability that force_quiescent_state() will need to do smp_send_reschedule(), which sends an IPI ... 5 Apr 2010 14:59

[PATCH RFC tip/core/rcu 04/10] rcu: ignore offline CPUs in last non-dyntick-idle CPU check
From: Lai Jiangshan <laijs(a)cn.fujitsu.com> Offline CPUs are not in nohz_cpu_mask, but can be ignored when checking for the last non-dyntick-idle CPU. This patch therefore only checks online CPUs for not being dyntick idle, allowing fast entry into full-system dyntick-idle state even when there are some offline C... 5 Apr 2010 14:59

tulip_stop_rxtx() failed (CSR5 0xf0260000 CSR6 0xb3862002) on DEC Alpha Personal Workstation 433au
Hi guys, I installed Debian unstable on an old digital workstation "DEC Digital Personal Workstation 433au" (Miata) which has an on-board tulip network controller. I'm not really using that network controller but an off-board intel e1000 controller. However, I found that the tulip driver produces a lot of noise ... 5 Apr 2010 13:52
