  • Pull more ACPI and power management updates from Rafael Wysocki:
    "These are regression fixes (leds-gpio, ACPI backlight driver,
    operating performance points library, ACPI device enumeration
    messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device
    PM), some cleanups in the operating performance points (OPP)
    framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of
    minor intel_pstate driver changes, a new MAINTAINERS entry for it and
    an ACPI fan driver change needed for better support of thermal
    management in user space.

    Specifics:

    - Fix a regression in leds-gpio introduced by a recent commit that
    inadvertently changed the name of one of the properties used by the
    driver (Fabio Estevam).

    - Fix a regression in the ACPI backlight driver introduced by a
    recent fix that missed one special case that had to be taken into
    account (Aaron Lu).

    - Drop the level of some new kernel messages from the ACPI core
    introduced by a recent commit to KERN_DEBUG which they should have
    used from the start and drop some other unuseful KERN_ERR messages
    printed by ACPI (Rafael J Wysocki).

    - Revert an incorrect commit modifying the cpupower tool (Prarit
    Bhargava).

    - Fix two regressions introduced by recent commits in the OPP library
    and clean up some existing minor issues in that code (Viresh
    Kumar).

    - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the
    tree (or drop it where that can be done) in order to make it
    possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf
    Hansson, Ludovic Desroches).

    There will be one more "CONFIG_PM_RUNTIME removal" batch after this
    one, because some new uses of it have been introduced during the
    current merge window, but that should be sufficient to finally get
    rid of it.

    - Make the ACPI EC driver more robust against race conditions related
    to GPE handler installation failures (Lv Zheng).

    - Prevent the ACPI device PM core code from attempting to disable
    GPEs that it has not enabled which confuses ACPICA and makes it
    report errors unnecessarily (Rafael J Wysocki).

    - Add a "force" command line switch to the intel_pstate driver to
    make it possible to override the blacklisting of some systems in
    that driver if needed (Ethan Zhao).

    - Improve intel_pstate code documentation and add a MAINTAINERS entry
    for it (Kristen Carlson Accardi).

    - Make the ACPI fan driver create cooling device interfaces witn
    names that reflect the IDs of the ACPI device objects they are
    associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B").

    That's necessary for user space thermal management tools to be able
    to connect the fans with the parts of the system they are supposed
    to be cooling properly. From Srinivas Pandruvada"

  • Pull ACPI and power management updates from Rafael Wysocki:
    "This time we have some more new material than we used to have during
    the last couple of development cycles.

    The most important part of it to me is the introduction of a unified
    interface for accessing device properties provided by platform
    firmware. It works with Device Trees and ACPI in a uniform way and
    drivers using it need not worry about where the properties come from
    as long as the platform firmware (either DT or ACPI) makes them
    available. It covers both devices and "bare" device node objects
    without struct device representation as that turns out to be necessary
    in some cases. This has been in the works for quite a few months (and
    development cycles) and has been approved by all of the relevant
    maintainers.

    On top of that, some drivers are switched over to the new interface
    (at25, leds-gpio, gpio_keys_polled) and some additional changes are
    made to the core GPIO subsystem to allow device drivers to manipulate
    GPIOs in the "canonical" way on platforms that provide GPIO
    information in their ACPI tables, but don't assign names to GPIO lines
    (in which case the driver needs to do that on the basis of what it
    knows about the device in question). That also has been approved by
    the GPIO core maintainers and the rfkill driver is now going to use
    it.

    Second is support for hardware P-states in the intel_pstate driver.
    It uses CPUID to detect whether or not the feature is supported by the
    processor in which case it will be enabled by default. However, it
    can be disabled entirely from the kernel command line if necessary.

    Next is support for a platform firmware interface based on ACPI
    operation regions used by the PMIC (Power Management Integrated
    Circuit) chips on the Intel Baytrail-T and Baytrail-T-CR platforms.
    That interface is used for manipulating power resources and for
    thermal management: sensor temperature reporting, trip point setting
    and so on.

    Also the ACPI core is now going to support the _DEP configuration
    information in a limited way. Basically, _DEP it supposed to reflect
    off-the-hierarchy dependencies between devices which may be very
    indirect, like when AML for one device accesses locations in an
    operation region handled by another device's driver (usually, the
    device depended on this way is a serial bus or GPIO controller). The
    support added this time is sufficient to make the ACPI battery driver
    work on Asus T100A, but it is general enough to be able to cover some
    other use cases in the future.

    Finally, we have a new cpufreq driver for the Loongson1B processor.

    In addition to the above, there are fixes and cleanups all over the
    place as usual and a traditional ACPICA update to a recent upstream
    release.

    As far as the fixes go, the ACPI LPSS (Low-power Subsystem) driver for
    Intel platforms should be able to handle power management of the DMA
    engine correctly, the cpufreq-dt driver should interact with the
    thermal subsystem in a better way and the ACPI backlight driver should
    handle some more corner cases, among other things.

    On top of the ACPICA update there are fixes for race conditions in the
    ACPICA's interrupt handling code which might lead to some random and
    strange looking failures on some systems.

    In the cleanups department the most visible part is the series of
    commits targeted at getting rid of the CONFIG_PM_RUNTIME configuration
    option. That was triggered by a discussion regarding the generic
    power domains code during which we realized that trying to support
    certain combinations of PM config options was painful and not really
    worth it, because nobody would use them in production anyway. For
    this reason, we decided to make CONFIG_PM_SLEEP select
    CONFIG_PM_RUNTIME and that lead to the conclusion that the latter
    became redundant and CONFIG_PM could be used instead of it. The
    material here makes that replacement in a major part of the tree, but
    there will be at least one more batch of that in the second part of
    the merge window.

    Specifics:

    - Support for retrieving device properties information from ACPI _DSD
    device configuration objects and a unified device properties
    interface for device drivers (and subsystems) on top of that. As
    stated above, this works with Device Trees and ACPI and allows
    device drivers to be written in a platform firmware (DT or ACPI)
    agnostic way. The at25, leds-gpio and gpio_keys_polled drivers are
    now going to use this new interface and the GPIO subsystem is
    additionally modified to allow device drivers to assign names to
    GPIO resources returned by ACPI _CRS objects (in case _DSD is not
    present or does not provide the expected data). The changes in
    this set are mostly from Mika Westerberg, Rafael J Wysocki, Aaron
    Lu, and Darren Hart with some fixes from others (Fabio Estevam,
    Geert Uytterhoeven).

    - Support for Hardware Managed Performance States (HWP) as described
    in Volume 3, section 14.4, of the Intel SDM in the intel_pstate
    driver. CPUID is used to detect whether or not the feature is
    supported by the processor. If supported, it will be enabled
    automatically unless the intel_pstate=no_hwp switch is present in
    the kernel command line. From Dirk Brandewie.

    - New Intel Broadwell-H ID for intel_pstate (Dirk Brandewie).

    - Support for firmware interface based on ACPI operation regions used
    by the PMIC chips on the Intel Baytrail-T and Baytrail-T-CR
    platforms for power resource control and thermal management (Aaron
    Lu).

    - Limited support for retrieving off-the-hierarchy dependencies
    between devices from ACPI _DEP device configuration objects and
    deferred probing support for the ACPI battery driver based on the
    _DEP information to make that driver work on Asus T100A (Lan
    Tianyu).

    - New cpufreq driver for the Loongson1B processor (Kelvin Cheung).

    - ACPICA update to upstream revision 20141107 which only affects
    tools (Bob Moore).

    - Fixes for race conditions in the ACPICA's interrupt handling code
    and in the ACPI code related to system suspend and resume (Lv Zheng
    and Rafael J Wysocki).

    - ACPI core fix for an RCU-related issue in the ioremap() regions
    management code that slowed down significantly after CPUs had been
    allowed to enter idle states even if they'd had RCU callbakcs
    queued and triggered some problems in certain proprietary graphics
    driver (and elsewhere). The fix replaces synchronize_rcu() in that
    code with synchronize_rcu_expedited() which makes the issue go
    away. From Konstantin Khlebnikov.

    - ACPI LPSS (Low-Power Subsystem) driver fix to handle power
    management of the DMA engine included into the LPSS correctly. The
    problem is that the DMA engine doesn't have ACPI PM support of its
    own and it simply is turned off when the last LPSS device having
    ACPI PM support goes into D3cold. To work around that, the PM
    domain used by the ACPI LPSS driver is redesigned so at least one
    device with ACPI PM support will be on as long as the DMA engine is
    in use. From Andy Shevchenko.

    - ACPI backlight driver fix to avoid using it on "Win8-compatible"
    systems where it doesn't work and where it was used by default by
    mistake (Aaron Lu).

    - Assorted minor ACPI core fixes and cleanups from Tomasz Nowicki,
    Sudeep Holla, Huang Rui, Hanjun Guo, Fabian Frederick, and Ashwin
    Chaugule (mostly related to the upcoming ARM64 support).

    - Intel RAPL (Running Average Power Limit) power capping driver fixes
    and improvements including new processor IDs (Jacob Pan).

    - Generic power domains modification to power up domains after
    attaching devices to them to meet the expectations of device
    drivers and bus types assuming devices to be accessible at probe
    time (Ulf Hansson).

    - Preliminary support for controlling device clocks from the generic
    power domains core code and modifications of the ARM/shmobile
    platform to use that feature (Ulf Hansson).

    - Assorted minor fixes and cleanups of the generic power domains core
    code (Ulf Hansson, Geert Uytterhoeven).

    - Assorted minor fixes and cleanups of the device clocks control code
    in the PM core (Geert Uytterhoeven, Grygorii Strashko).

    - Consolidation of device power management Kconfig options by making
    CONFIG_PM_SLEEP select CONFIG_PM_RUNTIME and removing the latter
    which is now redundant (Rafael J Wysocki and Kevin Hilman). That
    is the first batch of the changes needed for this purpose.

    - Core device runtime power management support code cleanup related
    to the execution of callbacks (Andrzej Hajda).

    - cpuidle ARM support improvements (Lorenzo Pieralisi).

    - cpuidle cleanup related to the CPUIDLE_FLAG_TIME_VALID flag and a
    new MAINTAINERS entry for ARM Exynos cpuidle (Daniel Lezcano and
    Bartlomiej Zolnierkiewicz).

    - New cpufreq driver callback (->ready) to be executed when the
    cpufreq core is ready to use a given policy object and cpufreq-dt
    driver modification to use that callback for cooling device
    registration (Viresh Kumar).

    - cpufreq core fixes and cleanups (Viresh Kumar, Vince Hsu, James
    Geboski, Tomeu Vizoso).

    - Assorted fixes and cleanups in the cpufreq-pcc, intel_pstate,
    cpufreq-dt, pxa2xx cpufreq drivers (Lenny Szubowicz, Ethan Zhao,
    Stefan Wahren, Petr Cvek).

    - OPP (Operating Performance Points) framework modification to allow
    OPPs to be removed too and update of a few cpufreq drivers
    (cpufreq-dt, exynos5440, imx6q, cpufreq) to remove OPPs (added
    during initialization) on driver removal (Viresh Kumar).

    - Hibernation core fixes and cleanups (Tina Ruchandani and Markus
    Elfring).

    - PM Kconfig fix related to CPU power management (Pankaj Dubey).

    - cpupower tool fix (Prarit Bhargava)"

  • After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
    selected) PM_RUNTIME is always set if PM is set, so quite a few
    depend on CONFIG_PM (or even dropped in some cases).

    Replace CONFIG_PM_RUNTIME with CONFIG_PM in the USB core code
    and documentation.

  • If usb_hub_claim_port() fails, no resources are deallocated and
    if stub_add_files() fails, port is not released.

    The patch fixes these issues and rearranges error handling code.

    Found by Linux Driver Verification project (linuxtesting.org).

  • The "status" is uninitialized so this creates a static checker warning.
    But it's harmless, we can just delete it.

  • Memset on a local variable may be removed when it is called just before the
    variable goes out of scope. Using memzero_explicit defeats this
    optimization. A simplified version of the semantic patch that makes this
    change is as follows: (http://coccinelle.lip6.fr/)

    //
    @@
    identifier x;
    type T;
    @@

    {
    ... when any
    T x[...];
    ... when any
    when exists
    - memset
    + memzero_explicit
    (x,
    -0,
    ...)
    ... when != x
    when strict
    }
    //

    This change was suggested by Daniel Borkmann

  • Endpoints halted on errors, and endpoints stopped manually both used
    the same ep->stopped_td to store the halted or stopped td. this causes
    confusion and possible races.

    There is no longer a need to use the ep->stopped_td variable to store
    the halted TD. A halted endpoint is handled immediately and we can pass
    it to the handling function directly.

  • If we need to change the max exit latency with a Evaluate Context
    command, we copy the old output slot context and use it as input
    context for the command. This also copies the dev_state bits which
    are supposed to be zero in the input slot context.
