When PMU context is migrating between CPUs, interrupt affinity is set as well. Only this should not happen when the CCN interrupt is not being used at all (the driver is using a hrtimer tick instead). Fixed now.

The cpufreq core fixes from Viresh Kumar are quite significant too as far as the number of commits goes and because they should reduce CPU online/offline overhead quite a bit in the majority of cases. From the new featues point of view, the ACPICA update (to upstream revision 20150515) adding support for new ACPI 6 material to ACPICA is the one that matters the most as some new significant features will be based on it going forward. Also included is an update of the ACPI device power management core to follow ACPI 6 (which in turn reflects the Windows' device PM implementation), a PM core extension to support wakeup interrupts in a more generic way and support for the ACPI _CCA device configuration object. The rest is mostly fixes and cleanups all over and some documentation updates, including new DT bindings for Operating Performance Points. There is one fix for a regression introduced in the 4.1 cycle, but it adds quite a number of lines of code, it wasn't really ready before Thursday and you were on vacation, so I refrained from pushing it on the last minute for 4.1. Specifics: - ACPICA update to upstream revision 20150515 including basic support for ACPI 6 features: new ACPI tables introduced by ACPI 6 (STAO, XENV, WPBT, NFIT, IORT), changes related to the other tables (DTRM, FADT, LPIT, MADT), new predefined names (_BTH, _CR3, _DSD, _LPI, _MTL, _PRR, _RDI, _RST, _TFP, _TSN), fixes and cleanups (Bob Moore, Lv Zheng). - ACPI device power management core code update to follow ACPI 6 which reflects the ACPI device power management implementation in Windows (Rafael J Wysocki). - rework of the backlight interface selection logic to reduce the number of kernel command line options and improve the handling of DMI quirks that may be involved in that and to make the code generally more straightforward (Hans de Goede). - fixes for the ACPI Embedded Controller (EC) driver related to the handling of EC transactions (Lv Zheng). - fix for a regression related to the ACPI resources management and resulting from a recent change of ACPI initialization code ordering (Rafael J Wysocki). - fix for a system initialization regression related to ACPI introduced during the 3.14 cycle and caused by running the code that switches the platform over to the ACPI mode too early in the initialization sequence (Rafael J Wysocki). - support for the ACPI _CCA device configuration object related to DMA cache coherence (Suravee Suthikulpanit). - ACPI/APEI fixes and cleanups (Jiri Kosina, Borislav Petkov). - ACPI battery driver cleanups (Luis Henriques, Mathias Krause). - ACPI processor driver cleanups (Hanjun Guo). - cleanups and documentation update related to the ACPI device properties interface based on _DSD (Rafael J Wysocki). - ACPI device power management fixes (Rafael J Wysocki). - assorted cleanups related to ACPI (Dominik Brodowski, Fabian Frederick, Lorenzo Pieralisi, Mathias Krause, Rafael J Wysocki). - fix for a long-standing issue causing General Protection Faults to be generated occasionally on return to user space after resume from ACPI-based suspend-to-RAM on 32-bit x86 (Ingo Molnar). - fix to make the suspend core code return -EBUSY consistently in all cases when system suspend is aborted due to wakeup detection (Ruchi Kandoi). - support for automated device wakeup IRQ handling allowing drivers to make their PM support more starightforward (Tony Lindgren). - new tracepoints for suspend-to-idle tracing and rework of the prepare/complete callbacks tracing in the PM core (Todd E Brandt, Rafael J Wysocki). - wakeup sources framework enhancements (Jin Qian). - new macro for noirq system PM callbacks (Grygorii Strashko). - assorted cleanups related to system suspend (Rafael J Wysocki). - cpuidle core cleanups to make the code more efficient (Rafael J Wysocki). - powernv/pseries cpuidle driver update (Shilpasri G Bhat). - cpufreq core fixes related to CPU online/offline that should reduce the overhead of these operations quite a bit, unless the CPU in question is physically going away (Viresh Kumar, Saravana Kannan). - serialization of cpufreq governor callbacks to avoid race conditions in some cases (Viresh Kumar). - intel_pstate driver fixes and cleanups (Doug Smythies, Prarit Bhargava, Joe Konno). - cpufreq driver (arm_big_little, cpufreq-dt, qoriq) updates (Sudeep Holla, Felipe Balbi, Tang Yuantian). - assorted cleanups in cpufreq drivers and core (Shailendra Verma, Fabian Frederick, Wang Long). - new Device Tree bindings for representing Operating Performance Points (Viresh Kumar). - updates for the common clock operations support code in the PM core (Rajendra Nayak, Geert Uytterhoeven). - PM domains core code update (Geert Uytterhoeven). - Intel Knights Landing support for the RAPL (Running Average Power Limit) power capping driver (Dasaratharaman Chandramouli). - fixes related to the floor frequency setting on Atom SoCs in the RAPL power capping driver (Ajay Thomas). -

This patch exports this information via the sysfs, which includes the aliases for the events. The aliases are listed by 'perf list', helping the users to specify the name of the event instead of the binary config values. Each event alias must accompany the 'source' code except for the following cases : 1) CCI-400 - cycles event, doesn't relate to an interface. 2) CCI-500 - Global events to the CCI. (Fixed source code = 0xf) Each CCI model provides two sets of attributes(format and event), which are dynamically populated before registering the PMU, to allow for the appropriate information.
