2007-08-25sched: adaptive scheduler granularityPeter Zijlstra
Instead of specifying the preemption granularity, specify the wanted latency. By fixing the granlarity to a constany the wakeup latency it a function of the number of running tasks on the rq. Invert this relation. sysctl_sched_granularity becomes a minimum for the dynamic granularity computed from the new sysctl_sched_latency. Then use this latency to do more intelligent granularity decisions: if there are fewer tasks running then we can schedule coarser. This helps performance while still always keeping the latency target. Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2007-08-23ACPI: don't duplicate input events on netlinkZhang Rui
The previous events patch added a netlink event for every user of the legacy /proc/acpi/event interface. However, some users of /proc/acpi/event are really input events, and they already report their events via the input layer. Introduce a new interface, acpi_bus_generate_netlink_event(), which is explicitly called by devices that want to repoprt events via netlink. This allows the input-like events to opt-out of generating netlink events. In summary: events that are sent via netlink: ac/battery/sbs thermal processor thinkpad_acpi dock/bay events that are sent via input layer: button video hotkey thinkpad_acpi hotkey asus_acpi/asus-laptop hotkey sonypi/sonylaptop Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
2007-08-23sched: fix broken SMT/MC optimizationsSuresh Siddha
On a four package system with HT - HT load balancing optimizations were broken. For example, if two tasks end up running on two logical threads of one of the packages, scheduler is not able to pull one of the tasks to a completely idle package. In this scenario, for nice-0 tasks, imbalance calculated by scheduler will be 512 and find_busiest_queue() will return 0 (as each cpu's load is 1024 > imbalance and has only one task running). Similarly MC scheduler optimizations also get fixed with this patch. [ mingo@elte.hu: restored fair balancing by increasing the fuzz and adding it back to the power decision, without the /2 factor. ] Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2007-08-23sched: sched_clock_idle_[sleep|wakeup]_event()Ingo Molnar
construct a more or less wall-clock time out of sched_clock(), by using ACPI-idle's existing knowledge about how much time we spent idling. This allows the rq clock to work around TSC-stops-in-C2, TSC-gets-corrupted-in-C3 type of problems. ( Besides the scheduler's statistics this also benefits blktrace and printk-timestamps as well. ) Furthermore, the precise before-C2/C3-sleep and after-C2/C3-wakeup callbacks allow the scheduler to get out the most of the period where the CPU has a reliable TSC. This results in slightly more precise task statistics. the ACPI bits were acked by Len. Signed-off-by: Ingo Molnar <mingo@elte.hu> Acked-by: Len Brown <len.brown@intel.com>
2007-08-22Apply memory policies to top two highest zones when highest zone is ZONE_MOVABLEMel Gorman
The NUMA layer only supports NUMA policies for the highest zone. When ZONE_MOVABLE is configured with kernelcore=, the the highest zone becomes ZONE_MOVABLE. The result is that policies are only applied to allocations like anonymous pages and page cache allocated from ZONE_MOVABLE when the zone is used. This patch applies policies to the two highest zones when the highest zone is ZONE_MOVABLE. As ZONE_MOVABLE consists of pages from the highest "real" zone, it's always functionally equivalent. The patch has been tested on a variety of machines both NUMA and non-NUMA covering x86, x86_64 and ppc64. No abnormal results were seen in kernbench, tbench, dbench or hackbench. It passes regression tests from the numactl package with and without kernelcore= once numactl tests are patched to wait for vmstat counters to update. akpm: this is the nasty hack to fix NUMA mempolicies in the presence of ZONE_MOVABLE and kernelcore= in 2.6.23. Christoph says "For .24 either merge the mobility or get the other solution that Mel is working on. That solution would only use a single zonelist per node and filter on the fly. That may help performance and also help to make memory policies work better."

2007-08-22fix NULL pointer dereference in __vm_enough_memory()Alan Cox
The new exec code inserts an accounted vma into an mm struct which is not current->mm. The existing memory check code has a hard coded assumption that this does not happen as does the security code. As the correct mm is known we pass the mm to the security method and the helper function. A new security test is added for the case where we need to pass the mm and the existing one is modified to pass current->mm to avoid the need to change large amounts of code.

2007-08-22Serial 8250: handle saving the clear-on-read bits from the LSR and MSRCorey Minyard
Reading the LSR clears the break, parity, frame error, and overrun bits in the 8250 chip, but these are not being saved in all places that read the LSR. Same goes for the MSR delta bits. Save the LSR bits off whenever the lsr is read so they can be handled later in the receive routine. Save the MSR bits to be handled in the modem status routine. Also, clear the stored bits and clear the interrupt registers before enabling interrupts, to avoid handling old values of the stored bits in the interrupt routines.
