      HID: usbhid: fix inconsistent reset/resume/reset-resume behavior · 972e6a99
      Alan Stern authored
      The usbhid driver has inconsistently duplicated code in its post-reset,
      resume, and reset-resume pathways.
      
      	reset-resume doesn't check HID_STARTED before trying to
      	restart the I/O queues.
      
      	resume fails to clear the HID_SUSPENDED flag if HID_STARTED
      	isn't set.
      
      	resume calls usbhid_restart_queues() with usbhid->lock held
      	and the others call it without holding the lock.
      
      The first item in particular causes a problem following a reset-resume
      if the driver hasn't started up its I/O.  URB submission fails because
      usbhid->urbin is NULL, and this triggers an unending reset-retry loop.
      
      This patch fixes the problem by creating a new subroutine,
      hid_restart_io(), to carry out all the common activities.  It also
      adds some checks that were missing in the original code:
      
      	After a reset, there's no need to clear any halted endpoints.
      
      	After a resume, if a reset is pending there's no need to
      	restart any I/O until the reset is finished.
      
      	After a resume, if the interrupt-IN endpoint is halted there's
      	no need to submit the input URB until the halt has been
      	cleared.

      HID: wiimote: Fix wiimote mp scale linearization · d3059673
      Cyan Ogilvie authored
      The wiimote motion plus gyros use two scales to report fast and slow
      rotation - below 440 deg/s uses 8192/440 units / deg/s, and above uses
      8192/2000 units / deg/s.
      
      Previously this driver attempted to linearize the two by scaling the fast
      rate by 18 and the slow by 9, but this results in a scale of
      8192*9/440 = ~167.564 for slow and 8192*18/2000 = 73.728 for fast.
      
      Correct the fast motion scale factor so that both report ~167.564
      units / deg/s

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for kernel v4.6.  There is quite a
        lot of interesting stuff going on.
      
        The patches to other subsystems and arch-wide are ACKed as far as
        possible, though I consider things like per-arch <asm/gpio.h> as
        essentially a part of the GPIO subsystem so it should not be needed.
      
        Core changes:
      
         - The gpio_chip is now a *real device*.  Until now the gpio chips
           were just piggybacking the parent device or (gasp) floating in
           space outside of the device model.
      
           We now finally make GPIO chips devices.  The gpio_chip will create
           a gpio_device which contains a struct device, and this gpio_device
           struct is kept private.  Anything that needs to be kept private
           from the rest of the kernel will gradually be moved over to the
           gpio_device.
      
         - As a result of making the gpio_device a real device, we have added
           resource management, so devm_gpiochip_add_data() will cut down on
           overhead and reduce code lines.  A huge slew of patches convert
           almost all drivers in the subsystem to use this.
      
         - Building on making the GPIO a real device, we add the first step of
           a new userspace ABI: the GPIO character device.  We take small
           steps here, so we first add a pure *information* ABI and the tool
           "lsgpio" that will list all GPIO devices on the system and all
           lines on these devices.
      
           We can now discover GPIOs properly from userspace.  We still have
           not come up with a way to actually *use* GPIOs from userspace.
      
         - To encourage people to use the character device for the future, we
           have it always-enabled when using GPIO.  The old sysfs ABI is still
           opt-in (and can be used in parallel), but is marked as deprecated.
      
           We will keep it around for the foreseeable future, but it will not
           be extended to cover ever more use cases.
      
        Cleanup:
      
         - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
           includes.
      
           This dates back to when GPIO was an opt-in feature and no shared
           library even existed: just a header file with proper prototypes was
           provided and all semantics were up to the arch to implement.  These
           patches make the GPIO chip even more a proper device and cleans out
           leftovers of the old in-kernel API here and there.
      
           Still some cruft is left but it's very little now.
      
         - There is still some clamping of return values for .get() going on,
           but we now return sane values in the vast majority of drivers and
           the errorpath is sanitized.  Some patches for powerpc, blackfin and
           unicore still drop in.
      
         - We continue to switch the ARM, MIPS, blackfin, m68k local GPIO
           implementations to use gpiochip_add_data() and cut down on code
           lines.
      
         - MPC8xxx is converted to use the generic GPIO helpers.
      
         - ATH79 is converted to use the generic GPIO helpers.
      
        New drivers:
      
         - WinSystems WS16C48
      
         - Acces 104-DIO-48E
      
         - F81866 (a F7188x variant)
      
         - Qoric (a MPC8xxx variant)
      
         - TS-4800
      
         - SPI serializers (pisosr): simple 74xx shift registers connected to
           SPI to obtain a dirt-cheap output-only GPIO expander.

      Pull arm64 updates from Catalin Marinas:
       "Here are the main arm64 updates for 4.6.  There are some relatively
        intrusive changes to support KASLR, the reworking of the kernel
        virtual memory layout and initial page table creation.
      
        Summary:
      
         - Initial page table creation reworked to avoid breaking large block
           mappings (huge pages) into smaller ones.  The ARM architecture
           requires break-before-make in such cases to avoid TLB conflicts but
           that's not always possible on live page tables
      
         - Kernel virtual memory layout: the kernel image is no longer linked
           to the bottom of the linear mapping (PAGE_OFFSET) but at the bottom
           of the vmalloc space, allowing the kernel to be loaded (nearly)
           anywhere in physical RAM
      
         - Kernel ASLR: position independent kernel Image and modules being
           randomly mapped in the vmalloc space with the randomness is
           provided by UEFI (efi_get_random_bytes() patches merged via the
           arm64 tree, acked by Matt Fleming)
      
         - Implement relative exception tables for arm64, required by KASLR
           (initial code for ARCH_HAS_RELATIVE_EXTABLE added to lib/extable.c
           but actual x86 conversion to deferred to 4.7 because of the merge
           dependencies)
      
         - Support for the User Access Override feature of ARMv8.2: this
           allows uaccess functions (get_user etc.) to be implemented using
           LDTR/STTR instructions.  Such instructions, when run by the kernel,
           perform unprivileged accesses adding an extra level of protection.
           The set_fs() macro is used to "upgrade" such instruction to
           privileged accesses via the UAO bit
      
         - Half-precision floating point support (part of ARMv8.2)
      
         - Optimisations for CPUs with or without a hardware prefetcher (using
           run-time code patching)
      
         - copy_page performance improvement to deal with 128 bytes at a time
      
         - Sanity checks on the CPU capabilities (via CPUID) to prevent
           incompatible secondary CPUs from being brought up (e.g.  weird
           big.LITTLE configurations)
      
         - valid_user_regs() reworked for better sanity check of the
           sigcontext information (restored pstate information)
      
         - ACPI parking protocol implementation
      
         - CONFIG_DEBUG_RODATA enabled by default
      
         - VDSO code marked as read-only
      
         - DEBUG_PAGEALLOC support
      
         - ARCH_HAS_UBSAN_SANITIZE_ALL enabled

         matter on it's own, but it seems like he is trying to get rid of all

       "Various enablers for assignment of Intel graphics devices and future
        support of vGPU devices (Alex Williamson).  This includes
      
         - Handling the vfio type1 interface as an API rather than a specific
           implementation, allowing multiple type1 providers.
      
         - Capability chains, similar to PCI device capabilities, that allow
           extending ioctls.  Extensions here include device specific regions
           and sparse mmap descriptions.  The former is used to expose non-PCI
           regions for IGD, including the OpRegion (particularly the Video
           BIOS Table), and read only PCI config access to the host and LPC
           bridge as drivers often depend on identifying those devices.
      
           Sparse mmaps here are used to describe the MSIx vector table, which
           vfio has always protected from mmap, but never had an API to
           explicitly define that protection.  In future vGPU support this is
           expected to allow the description of PCI BARs that may mix direct
           access and emulated access within a single region.
      
         - The ability to expose the shadow ROM as an option ROM as IGD use
           cases may rely on the ROM even though the physical device does not
           make use of a PCI option ROM BAR"

      Linus Torvalds authored
      Pull libnvdimm updates from Dan Williams:
      
       - Asynchronous address range scrub:
      
           Given the capacities of next generation persistent memory devices a
           scrub operation to find all poison may take 10s of seconds.  We
           want this scrub work to be done asynchronously with the rest of
           system initialization, so we move it out of line from the NFIT
           probing, i.e. acpi_nfit_add().
      
       - Clear poison:
      
           ACPI 6.1 introduces the ability to send "clear error" commands to
           the ACPI0012:00 device representing the root of an "nvdimm bus".
           Similar to relocating a bad block on a disk, this support clears
           media errors in response to a write.
      
       - Persistent memory resource tracking:
      
           A persistent memory range may be designated as simply "reserved" by
           platform firmware in the efi/e820 memory map.  Later when the NFIT
           driver loads it discovers that the range is "Persistent Memory".
      
           The NFIT bus driver inserts a resource to advertise that
           "persistent" attribute in the system resource tree for /proc/iomem
           and kernel-internal usages.
      
       - Miscellaneous cleanups and fixes:
      
           Workaround section misaligned pmem ranges when allocating a struct
           page memmap, fix handling of the read-only case in the ioctl path,
           and clean up block device major number allocation.

      Linus Torvalds authored
      Pull device mapper updates from Mike Snitzer:
      
       - Most attention this cycle went to optimizing blk-mq request-based DM
         (dm-mq) that is used exclussively by DM multipath:
      
           - A stable fix for dm-mq that eliminates excessive context
             switching offers the biggest performance improvement (for both
             IOPs and throughput).
      
           - But more work is needed, during the next cycle, to reduce
             spinlock contention in DM multipath on large NUMA systems.
      
       - A stable fix for a NULL pointer seen when DM stats is enabled on a DM
         multipath device that must requeue an IO due to path failure.
      
       - A stable fix for DM snapshot to disallow the COW and origin devices
         from being identical.  This amounts to graceful failure in the face
         of userspace error because these devices shouldn't ever be identical.
      
       - Stable fixes for DM cache and DM thin provisioning to address crashes
         seen if/when their respective metadata device experiences failures
         that cause the transition to 'fail_io' mode.
      
       - The DM cache 'mq' policy is now an alias for the 'smq' policy.  The
         'smq' policy proved to be consistently better than 'mq'.  As such
         'mq', with all its complex user-facing tunables, has been eliminated.
      
       - Improve DM thin provisioning to consistently return -ENOSPC once the
         thin-pool's data volume is out of space.
      
       - Improve DM core to properly handle error propagation if
         bio_integrity_clone() fails in clone_bio().
      
       - Other small cleanups and improvements to DM core.

      Pull power management and ACPI updates from Rafael Wysocki:
       "This time the majority of changes go into cpufreq and they are
        significant.
      
        First off, the way CPU frequency updates are triggered is different
        now.  Instead of having to set up and manage a deferrable timer for
        each CPU in the system to evaluate and possibly change its frequency
        periodically, cpufreq governors set up callbacks to be invoked by the
        scheduler on a regular basis (basically on utilization updates).  The
        "old" governors, "ondemand" and "conservative", still do all of their
        work in process context (although that is triggered by the scheduler
        now), but intel_pstate does it all in the callback invoked by the
        scheduler with no need for any additional asynchronous processing.
      
        Of course, this eliminates the overhead related to the management of
        all those timers, but also it allows the cpufreq governor code to be
        simplified quite a bit.  On top of that, the common code and data
        structures used by the "ondemand" and "conservative" governors are
        cleaned up and made more straightforward and some long-standing and
        quite annoying problems are addressed.  In particular, the handling of
        governor sysfs attributes is modified and the related locking becomes
        more fine grained which allows some concurrency problems to be avoided
        (particularly deadlocks with the core cpufreq code).
      
        In principle, the new mechanism for triggering frequency updates
        allows utilization information to be passed from the scheduler to
        cpufreq.  Although the current code doesn't make use of it, in the
        works is a new cpufreq governor that will make decisions based on the
        scheduler's utilization data.  That should allow the scheduler and
        cpufreq to work more closely together in the long run.
      
        In addition to the core and governor changes, cpufreq drivers are
        updated too.  Fixes and optimizations go into intel_pstate, the
        cpufreq-dt driver is updated on top of some modification in the
        Operating Performance Points (OPP) framework and there are fixes and
        other updates in the powernv cpufreq driver.
      
        Apart from the cpufreq updates there is some new ACPICA material,
        including a fix for a problem introduced by previous ACPICA updates,
        and some less significant changes in the ACPI code, like CPPC code
        optimizations, ACPI processor driver cleanups and support for loading
        ACPI tables from initrd.
      
        Also updated are the generic power domains framework, the Intel RAPL
        power capping driver and the turbostat utility and we have a bunch of
        traditional assorted fixes and cleanups.
      
        Specifics:
      
         - Redesign of cpufreq governors and the intel_pstate driver to make
           them use callbacks invoked by the scheduler to trigger CPU
           frequency evaluation instead of using per-CPU deferrable timers for
           that purpose (Rafael Wysocki).
      
         - Reorganization and cleanup of cpufreq governor code to make it more
           straightforward and fix some concurrency problems in it (Rafael
           Wysocki, Viresh Kumar).
      
         - Cleanup and improvements of locking in the cpufreq core (Viresh
           Kumar).
      
         - Assorted cleanups in the cpufreq core (Rafael Wysocki, Viresh
           Kumar, Eric Biggers).
      
         - intel_pstate driver updates including fixes, optimizations and a
           modification to make it enable enable hardware-coordinated P-state
           selection (HWP) by default if supported by the processor (Philippe
           Longepe, Srinivas Pandruvada, Rafael Wysocki, Viresh Kumar, Felipe
           Franciosi).
      
         - Operating Performance Points (OPP) framework updates to improve its
           handling of voltage regulators and device clocks and updates of the
           cpufreq-dt driver on top of that (Viresh Kumar, Jon Hunter).
      
         - Updates of the powernv cpufreq driver to fix initialization and
           cleanup problems in it and correct its worker thread handling with
           respect to CPU offline, new powernv_throttle tracepoint (Shilpasri
           Bhat).
      
         - ACPI cpufreq driver optimization and cleanup (Rafael Wysocki).
      
         - ACPICA updates including one fix for a regression introduced by
           previos changes in the ACPICA code (Bob Moore, Lv Zheng, David Box,
           Colin Ian King).
      
         - Support for installing ACPI tables from initrd (Lv Zheng).
      
         - Optimizations of the ACPI CPPC code (Prashanth Prakash, Ashwin
           Chaugule).
      
         - Support for _HID(ACPI0010) devices (ACPI processor containers) and
           ACPI processor driver cleanups (Sudeep Holla).
      
         - Support for ACPI-based enumeration of the AMBA bus (Graeme Gregory,
           Aleksey Makarov).
      
         - Modification of the ACPI PCI IRQ management code to make it treat
           255 in the Interrupt Line register as "not connected" on x86 (as
           per the specification) and avoid attempts to use that value as a
           valid interrupt vector (Chen Fan).
      
         - ACPI APEI fixes related to resource leaks (Josh Hunt).
      
         - Removal of modularity from a few ACPI drivers (BGRT, GHES,
           intel_pmic_crc) that cannot be built as modules in practice (Paul
           Gortmaker).
      
         - PNP framework update to make it treat ACPI_RESOURCE_TYPE_SERIAL_BUS
           as a valid resource type (Harb Abdulhamid).
      
         - New device ID (future AMD I2C controller) in the ACPI driver for
           AMD SoCs (APD) and in the designware I2C driver (Xiangliang Yu).
      
         - Assorted ACPI cleanups (Colin Ian King, Kaiyen Chang, Oleg Drokin).
      
         - cpuidle menu governor optimization to avoid a square root
           computation in it (Rasmus Villemoes).
      
         - Fix for potential use-after-free in the generic device properties
           framework (Heikki Krogerus).
      
         - Updates of the generic power domains (genpd) framework including
           support for multiple power states of a domain, fixes and debugfs
           output improvements (Axel Haslam, Jon Hunter, Laurent Pinchart,
           Geert Uytterhoeven).
      
         - Intel RAPL power capping driver updates to reduce IPI overhead in
           it (Jacob Pan).
      
         - System suspend/hibernation code cleanups (Eric Biggers, Saurabh
           Sengar).
      
         - Year 2038 fix for the process freezer (Abhilash Jindal).
      
         - turbostat utility updates including new features (decoding of more
           registers and CPUID fields, sub-second intervals support, GFX MHz
           and RC6 printout, --out command line option), fixes (syscall jitter
           detection and workaround, reductioin of the number of syscalls
           made, fixes related to Xeon x200 processors, compiler warning
           fixes) and cleanups (Len Brown, Hubert Chrzaniuk, Chen Yu)"
