* KVM: fix !SMP build errorIngo Molnar2007-11-091-2/+5
| | | | | | | | | | | | fix a !SMP build error: drivers/kvm/kvm_main.c: In function 'kvm_flush_remote_tlbs': drivers/kvm/kvm_main.c:220: error: implicit declaration of function 'smp_call_function_mask' (and also avoid unused function warning related to up_smp_call_function() not making use of the 'func' parameter.)

* x86: make nmi_cpu_busy() always definedIngo Molnar2007-11-091-2/+2

| | | | | | | | | | | | | | | | | | | Yanmin Zhang reported an aim7 regression and bisected it down to: | commit 38ad464d410dadceda1563f36bdb0be7fe4c8938 | Author: Ingo Molnar <mingo@elte.hu> | Date: Mon Oct 15 17:00:02 2007 +0200 | | sched: uniform tunings | | use the same defaults on both UP and SMP. fix this by reintroducing similar SMP tunings again. This resolves the regression. (also update the comments to match the ilog2(nr_cpus) tuning effect) Signed-off-by: Ingo Molnar <mingo@elte.hu>
* sched: restore deterministic CPU accounting on powerpcPaul Mackerras2007-11-096-43/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | Since powerpc started using CONFIG_GENERIC_CLOCKEVENTS, the deterministic CPU accounting (CONFIG_VIRT_CPU_ACCOUNTING) has been broken on powerpc, because we end up counting user time twice: once in timer_interrupt() and once in update_process_times(). This fixes the problem by pulling the code in update_process_times that updates utime and stime into a separate function called account_process_tick. If CONFIG_VIRT_CPU_ACCOUNTING is not defined, there is a version of account_process_tick in kernel/timer.c that simply accounts a whole tick to either utime or stime as before. If CONFIG_VIRT_CPU_ACCOUNTING is defined, then arch code gets to implement account_process_tick. This also lets us simplify the s390 code a bit; it means that the s390 timer interrupt can now call update_process_times even when CONFIG_VIRT_CPU_ACCOUNTING is turned on, and can just implement a suitable account_process_tick(). account_process_tick() now takes the task_struct * as an argument. Tested both with and without CONFIG_VIRT_CPU_ACCOUNTING. Signed-off-by: Paul Mackerras <paulus@samba.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* sched: fix delay accounting regressionBalbir Singh2007-11-091-5/+6
| | | | | | | | | | | | | Fix the delay accounting regression introduced by commit 75d4ef16a6aa84f708188bada182315f80aab6fa. rq no longer has sched_info data associated with it. task_struct sched_info structure is used by delay accounting to provide back statistics to user space. also remove direct use of sched_clock() (which is not a valid thing to do anymore) and use rq->clock instead.

* sched: reintroduce the sched_min_granularity tunablePeter Zijlstra2007-11-094-13/+41
| | | | | | | | | | | | | | | we lost the sched_min_granularity tunable to a clever optimization that uses the sched_latency/min_granularity ratio - but the ratio is quite unintuitive to users and can also crash the kernel if the ratio is set to 0. So reintroduce the min_granularity tunable, while keeping the ratio maintained internally. no functionality changed.
