Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki). In particular, the previously added erroneous support for the _SUB object is dropped, the concatenate operator will support all ACPI objects now, the Debug Object handling is improved, the SuperName handling of parameters being control methods is fixed, the ObjectType operator handling is updated to follow ACPI 5.0A and the handling of CondRefOf and RefOf is updated accordingly, module-level code will be executed after loading each ACPI table now (instead of being run once after all tables containing AML have been loaded), the Operation Region handlers management is updated to fix some reported problems and a the ACPICA code in the kernel is more in line with the upstream now. - Update the ACPI backlight driver to provide information on whether or not it will generate key-presses for brightness change hotkeys and update some platform drivers (dell-wmi, thinkpad_acpi) to use that information to avoid sending double key-events to users pace for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht). - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard). - Fix the handling of the list of device IDs of device objects found in the ACPI namespace and add a helper for checking if there is a device object for a given device ID (Lukas Wunner). - Change the logic in the ACPI namespace scanning code to create struct acpi_device objects for all ACPI device objects found in the namespace even if _STA fails for them which helps to avoid device enumeration problems on Microsoft Surface 3 (Aaron Lu). - Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). - Assorted updates of the PM core and related code (Julia Lawall, Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf Hansson). - PNP bus type updates (Christophe Le Roy, Heiner Kallweit). -

The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over. Specifics: - Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki).

Merge branch 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup updates from Tejun Heo: - cgroup v2 interface is now official. It's no longer hidden behind a devel flag and can be mounted using the new cgroup2 fs type. Unfortunately, cpu v2 interface hasn't made it yet due to the discussion around in-process hierarchical resource distribution and only memory and io controllers can be used on the v2 interface at the moment. - The existing documentation which has always been a bit of mess is relocated under Documentation/cgroup-v1/. Documentation/cgroup-v2.txt is added as the authoritative documentation for the v2 interface. - Some features are added through for-4.5-ancestor-test branch to enable netfilter xt_cgroup match to use cgroup v2 paths. The actual netfilter changes will be merged through the net tree which pulled in the said branch. - Various cleanups * 'for-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup: rename cgroup documentations cgroup: fix a typo. cgroup: Remove resource_counter.txt in Documentation/cgroup-legacy/00-INDEX. cgroup: demote subsystem init messages to KERN_DEBUG cgroup: Fix uninitialized variable warning cgroup: put controller Kconfig options in meaningful order cgroup: clean up the kernel configuration menu nomenclature cgroup_pids: fix a typo.

Pull misc vfs updates from Al Viro: "All kinds of stuff. That probably should've been 5 or 6 separate branches, but by the time I'd realized how large and mixed that bag had become it had been too close to -final to play with rebasing. Some fs/namei.c cleanups there, memdup_user_nul() introduction and switching open-coded instances, burying long-dead code, whack-a-mole of various kinds, several new helpers for ->llseek(), assorted cleanups and fixes from various people, etc. One piece probably deserves special mention - Neil's lookup_one_len_unlocked(). Similar to lookup_one_len(), but gets called without ->i_mutex and tries to avoid ever taking it. That, of course, means that it's not useful for any directory modifications, but things like getting inode attributes in nfds readdirplus are fine with that. I really should've asked for moratorium on lookup-related changes this cycle, but since I hadn't done that early enough... I *am* asking for that for the coming cycle, though - I'm going to try and get conversion of i_mutex to rwsem with ->lookup() done under lock taken shared. There will be a patch closer to the end of the window, along the lines of the one Linus had posted last May - mechanical conversion of ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/ inode_is_locked()/inode_lock_nested().

configfs: implement binary attributes
ConfigFS lacked binary attributes up until now. This patch introduces support for binary attributes in a somewhat similar manner of sysfs binary attributes albeit with changes that fit the configfs usage model. Problems that configfs binary attributes fix are everything that requires a binary blob as part of the configuration of a resource, such as bitstream loading for FPGAs, DTBs for dynamically created devices etc. Look at Documentation/filesystems/configfs/configfs.txt for internals and howto use them. This patch is against linux-next as of today that contains Christoph's configfs rework.
