2010-05-10rcu: shrink rcutiny by making synchronize_rcu_bh() be inlinePaul E. McKenney4-10/+15
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. Signed-off-by: Paul E. McKenney <[email protected]>
2010-05-10rcu: fix now-bogus rcu_scheduler_active comments.Paul E. McKenney1-2/+4

2010-05-10rcu: ignore offline CPUs in last non-dyntick-idle CPU checkLai Jiangshan1-1/+1
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 CPUs.

2010-05-10rcu: move some code from macro to functionLai Jiangshan1-9/+9
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 called from rcu_init_one(), depends on the initialization of the ->rda[] array.

2010-05-10rcu: substitute set_need_resched for sending resched IPIsPaul E. McKenney1-0/+10
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 and is therefore more expensive on most architectures.

2010-05-10rcu: optionally leave lockdep enabled after RCU lockdep splatLai Jiangshan3-4/+26
There is no need to disable lockdep after an RCU lockdep splat, so remove the debug_lockdeps_off() from lockdep_rcu_dereference(). To avoid repeated lockdep splats, use a static variable in the inlined rcu_dereference_check() and rcu_dereference_protected() macros so that a given instance splats only once, but so that multiple instances can be detected per boot. This is controlled by a new config variable CONFIG_PROVE_RCU_REPEATEDLY, which is disabled by default. This provides the normal lockdep behavior by default, but permits people who want to find multiple RCU-lockdep splats per boot to easily do so.

2010-05-09cpuidle: Fix incorrect optimizationArjan van de Ven1-5/+4
commit 672917dcc78 ("cpuidle: menu governor: reduce latency on exit") added an optimization, where the analysis on the past idle period moved from the end of idle, to the beginning of the new idle. Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

2010-05-07md: restore ability of spare drives to spin down.NeilBrown1-2/+8
Some time ago we stopped the clean/active metadata updates from being written to a 'spare' device in most cases so that it could spin down and say spun down. Device failure/removal etc are still recorded on spares. However commit 51d5668cb2e3fd1827a55 broke this 50% of the time, depending on whether the event count is even or odd. The change log entry said: This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, how ever the code makes no attempt to create that alignment, so it could take arbitrarily long. So when we find that clean/dirty is not aligned with odd/even, force a second metadata-update immediately. There are already cases where a second metadata-update is needed immediately (e.g. when a device fails during the metadata update). We just piggy-back on that.

2010-05-06V4L/DVB: saa7146: fix regression of the av7110/budget-av driverHans Verkuil5-23/+13
An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix regression where v4l2_device was registered too late) caused a new regression in the av7110 driver. Reverted the old fix and fixed the problem in the mxb driver instead. Tested on mxb and budget-av cards. The real problem is that the saa7146 framework has separate probe() and attach() driver callbacks which should be rolled into one. This is now done for the mxb driver, but others should do the same. Lack of hardware makes this hard to do, though. I hope to get hold of some hexium cards and then I can try to improve the framework to prevent this from happening again.

C implementation do not need aligned end address and ASM code do aligned in their macros 4. ASM optimized CACHE_RANGE_LOOP_1/2 macros needs to get aligned end address. Because end address is compound from start + size, end address is the first address which is exclude. Here is the corresponding code which describe it. + int align = ~(line_length - 1); + end = ((end & align) == end) ? end - line_length : end & align; a) end is aligned: it is necessary to subtruct line length because we don't want to work with next cacheline b) end address is not aligned: Just align it to be ready for ASM code.
