2010-11-26perf events: Default to using event__process_lostArnaldo Carvalho de Melo
Tool developers have to fill in a 'perf_event_ops' method table to specify how to handle each event, so far the ones that were not explicitely especified would get a stub that would just discard the event. Change that so that tool developers can get the lost event details and the total number of such events at the end of 'perf report -D' output.

2010-11-26perf record: Add option to disable collecting build-idsArnaldo Carvalho de Melo
Collecting build-ids for long running sessions may take a long time because it needs to traverse the whole just collected perf.data stream of events, marking the DSOs that had hits and then looking for the .note.gnu.build-id ELF section. For things like the 'trace' tool that records and right away consumes the data on systems where its unlikely that the DSOs being monitored will change while 'trace' runs, it is desirable to remove build id collection, so add a -B/--no-buildid option to perf record to allow such use case. Longer term we'll avoid all this if we, at DSO load time, in the kernel, take advantage of this slow code path to collect the build-id and stash it somewhere, so that we can insert it in the PERF_RECORD_MMAP event.

2010-11-26ALSA: hda - Use ALC_INIT_DEFAULT for really default initializationTakashi Iwai
When SKU assid gives no valid bits for 0x38, the driver didn't take any action, so far. This resulted in the missing initialization for external amps, etc, thus the silent output in the end. Especially users hit this problem on ALC888 newly since 2.6.35, where the driver doesn't force to use ALC_INIT_DEFAULT any more. This patch sets the default initialization scheme to use ALC_INIT_DEFAULT when no valid bits are set for SKU assid.

2010-11-26perf, arch: Cleanup perf-pmu init vs lockup-detectorPeter Zijlstra
The perf hardware pmu got initialized at various points in the boot, some before early_initcall() some after (notably arch_initcall). The problem is that the NMI lockup detector is ran from early_initcall() and expects the hardware pmu to be present. Sanitize this by moving all architecture hardware pmu implementations to initialize at early_initcall() and move the lockup detector to an explicit initcall right after that.

2010-11-26mutexes, sched: Introduce arch_mutex_cpu_relax()Gerald Schaefer
The spinning mutex implementation uses cpu_relax() in busy loops as a compiler barrier. Depending on the architecture, cpu_relax() may do more than needed in this specific mutex spin loops. On System z we also give up the time slice of the virtual cpu in cpu_relax(), which prevents effective spinning on the mutex. This patch replaces cpu_relax() in the spinning mutex code with arch_mutex_cpu_relax(), which can be defined by each architecture that selects HAVE_ARCH_MUTEX_CPU_RELAX. The default is still cpu_relax(), so this patch should not affect other architectures than System z for now.

2010-11-26nohz: Fix printk_needs_cpu() return value on offline cpusHeiko Carstens
This patch fixes a hang observed with 2.6.32 kernels where timers got enqueued on offline cpus. printk_needs_cpu() may return 1 if called on offline cpus. When a cpu gets offlined it schedules the idle process which, before killing its own cpu, will call tick_nohz_stop_sched_tick(). That function in turn will call printk_needs_cpu() in order to check if the local tick can be disabled. On offline cpus this function should naturally return 0 since regardless if the tick gets disabled or not the cpu will be dead short after. That is besides the fact that __cpu_disable() should already have made sure that no interrupts on the offlined cpu will be delivered anyway. In this case it prevents tick_nohz_stop_sched_tick() to call select_nohz_load_balancer(). No idea if that really is a problem. However what made me debug this is that on 2.6.32 the function get_nohz_load_balancer() is used within __mod_timer() to select a cpu on which a timer gets enqueued. If printk_needs_cpu() returns 1 then the nohz_load_balancer cpu doesn't get updated when a cpu gets offlined. It may contain the cpu number of an offline cpu. In turn timers get enqueued on an offline cpu and not very surprisingly they never expire and cause system hangs. This has been observed 2.6.32 kernels. On current kernels __mod_timer() uses get_nohz_timer_target() which doesn't have that problem. However there might be other problems because of the too early exit tick_nohz_stop_sched_tick() in case a cpu goes offline. Easiest way to fix this is just to test if the current cpu is offline and call printk_tick() directly which clears the condition. Alternatively I tried a cpu hotplug notifier which would clear the condition, however between calling the notifier function and printk_needs_cpu() something could have called printk() again and the problem is back again. This seems to be the safest fix.

2010-11-26printk: Fix wake_up_klogd() vs cpu hotplugHeiko Carstens
wake_up_klogd() may get called from preemptible context but uses __raw_get_cpu_var() to write to a per cpu variable. If it gets preempted between getting the address and writing to it, the cpu in question could be offline if the process gets scheduled back and hence writes to the per cpu data of an offline cpu. This buggy behaviour was introduced with fa33507a "printk: robustify printk, fix #2" which was supposed to fix a "using smp_processor_id() in preemptible" warning. Let's use this_cpu_write() instead which disables preemption and makes sure that the outlined scenario cannot happen.

2010-11-26x86, perf, nmi: Disable perf if counters are not accessibleDon Zickus
In a kvm virt guests, the perf counters are not emulated. Instead they return zero on a rdmsrl. The perf nmi handler uses the fact that crossing a zero means the counter overflowed (for those counters that do not have specific interrupt bits). Therefore on kvm guests, perf will swallow all NMIs thinking the counters overflowed. This causes problems for subsystems like kgdb which needs NMIs to do its magic. This problem was discovered by running kgdb tests. The solution is to write garbage into a perf counter during the initialization and hopefully reading back the same number. On kvm guests, the value will be read back as zero and we disable perf as a result.

Incorrect rcu check was used as rcu isn't done under mutex here. Force check to 1 for now, to stop it from complaining. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2010-11-25[S390] qdio: free indicator after reset is finishedJan Glauber
The qdio device indicator is freed before the device is notified that the indicator is reset. This sequence contains a race when the freed indicator is used by a new device while the reset of the indicator is still pending. Do the reset operation before freeing the indicator to avoid that potential race. Signed-off-by: Jan Glauber <jang@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2010-11-25[S390] nmi: fix clock comparator revalidationHeiko Carstens
On each machine check all registers are revalidated. The save area for the clock comparator however only contains the upper most seven bytes of the former contents, if valid. Therefore the machine check handler uses a store clock instruction to get the current time and writes that to the clock comparator register which in turn will generate an immediate timer interrupt. However within the lowcore the expected time of the next timer interrupt is stored. If the interrupt happens before that time the handler won't be called. In turn the clock comparator won't be reprogrammed and therefore the interrupt condition stays pending which causes an interrupt loop until the expected time is reached. On NOHZ machines this can result in unresponsive machines since the time of the next expected interrupted can be a couple of days in the future. To fix this just revalidate the clock comparator register with the expected value. In addition the special handling for udelay must be changed as well.

2010-11-25ALSA: hda - Fix ALC660-VD/ALC861-VD capture/playback mixersHerton Ronaldo Krzesinski
The mixer nids passed to alc_auto_create_input_ctls are wrong: 0x15 is a pin, and 0x09 is the ADC on both ALC660-VD/ALC861-VD. Thus with current code, input playback volume/switches and input source mixer controls are not created, and recording doesn't work. Select correct mixers, 0x0b (input playback mixer) and 0x22 (capture source mixer).
