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.

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 Signed-off-by: Cyan Ogilvie <cyan.ogilvie@gmail.com> Reviewed-by: David Herrmann <dh.herrmann@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

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. - Texas Instruments TPIC2810 - Texas Instruments TPS65218 - Texas Instruments TPS65912 - X-Gene (ARM64) standby GPIO controller" * tag 'gpio-v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (194 commits) Revert "Share upstreaming patches" gpio: mcp23s08: Fix clearing of interrupt. gpiolib: Fix comment referring to gpio_*() in gpiod_*() gpio: pca953x: Fix pca953x_gpio_set_multiple() on 64-bit gpio: xgene: Fix kconfig for standby GIPO contoller gpio: Add generic serializer DT binding gpio: uapi: use 0xB4 as ioctl() major gpio: tps65912: fix bad merge Revert "gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free" gpio: omap: drop dev field from gpio_bank structure gpio: mpc8xxx: Slightly update the code for better readability gpio: mpc8xxx: Remove *read_reg and *write_reg from struct mpc8xxx_gpio_chip gpio: mpc8xxx: Fixup setting gpio direction output gpio: mcp23s08: Add support for mcp23s18 dt-bindings: gpio: altera: Fix altr,interrupt-type property gpio: add driver for MEN 16Z127 GPIO controller gpio: lp3943: Drop pin_used and lp3943_gpio_request/lp3943_gpio_free gpio: timberdale: Switch to devm_ioremap_resource() gpio: ts4800: Add IMX51 dependency gpiolib: rewrite gpiodev_add_to_list ...

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 - Erratum workaround Cavium ThunderX SoC - set_pte_at() fix for PROT_NONE mappings - Code clean-ups" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (99 commits) arm64: kasan: Fix zero shadow mapping overriding kernel image shadow arm64: kasan: Use actual memory node when populating the kernel image shadow arm64: Update PTE_RDONLY in set_pte_at() for PROT_NONE permission arm64: Fix misspellings in comments. arm64: efi: add missing frame pointer assignment arm64: make mrs_s prefixing implicit in read_cpuid arm64: enable CONFIG_DEBUG_RODATA by default arm64: Rework valid_user_regs arm64: mm: check at build time that PAGE_OFFSET divides the VA space evenly arm64: KVM: Move kvm_call_hyp back to its original localtion arm64: mm: treat memstart_addr as a signed quantity arm64: mm: list kernel sections in order arm64: lse: deal with clobbered IP registers after branch via PLT arm64: mm: dump: Use VA_START directly instead of private LOWEST_ADDR arm64: kconfig: add submenu for 8.2 architectural features arm64: kernel: acpi: fix ioremap in ACPI parking protocol cpu_postboot arm64: Add support for Half precision floating point arm64: Remove fixmap include fragility arm64: Add workaround for Cavium erratum 27456 arm64: mm: Mark .rodata as RO ...

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" * tag 'vfio-v4.6-rc1' of git://github.com/awilliam/linux-vfio: vfio/pci: return -EFAULT if copy_to_user fails vfio/pci: Expose shadow ROM as PCI option ROM vfio/pci: Intel IGD host and LCP bridge config space access vfio/pci: Intel IGD OpRegion support vfio/pci: Enable virtual register in PCI config space vfio/pci: Add infrastructure for additional device specific regions vfio: Define device specific region type capability vfio/pci: Include sparse mmap capability for MSI-X table regions vfio: Define sparse mmap capability for regions vfio: Add capability chain helpers vfio: Define capability chains vfio: If an IOMMU backend fails, keep looking vfio/pci: Fix unsigned comparison overflow

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. * tag 'libnvdimm-for-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (26 commits) libnvdimm, pmem: clear poison on write libnvdimm, pmem: fix kmap_atomic() leak in error path nvdimm/btt: don't allocate unused major device number nvdimm/blk: don't allocate unused major device number pmem: don't allocate unused major device number ACPI: Change NFIT driver to insert new resource resource: Export insert_resource and remove_resource resource: Add remove_resource interface resource: Change __request_region to inherit from immediate parent libnvdimm, pmem: fix ia64 build, use PHYS_PFN nfit, libnvdimm: clear poison command support libnvdimm, pfn: 'resource'-address and 'size' attributes for pfn devices libnvdimm, pmem: adjust for section collisions with 'System RAM' libnvdimm, pmem: fix 'pfn' support for section-misaligned namespaces libnvdimm: Fix security issue with DSM IOCTL. libnvdimm: Clean-up access mode check. tools/testing/nvdimm: expand ars unit testing nfit: disable userspace initiated ars during scrub nfit: scrub and register regions in a workqueue nfit, libnvdimm: async region scrub workqueue ...

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. * tag 'dm-4.6-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (41 commits) dm: fix rq_end_stats() NULL pointer in dm_requeue_original_request() dm thin: consistently return -ENOSPC if pool has run out of data space dm cache: bump the target version dm cache: make sure every metadata function checks fail_io dm: add missing newline between DM_DEBUG_BLOCK_STACK_TRACING and DM_BUFIO dm cache policy smq: clarify that mq registration failure was for 'mq' dm: return error if bio_integrity_clone() fails in clone_bio() dm thin metadata: don't issue prefetches if a transaction abort has failed dm snapshot: disallow the COW and origin devices from being identical dm cache: make the 'mq' policy an alias for 'smq' dm: drop unnecessary assignment of md->queue dm: reorder 'struct mapped_device' members to fix alignment and holes dm: remove dummy definition of 'struct dm_table' dm: add 'dm_numa_node' module parameter dm thin metadata: remove needless newline from subtree_dec() DMERR message dm mpath: cleanup reinstate_path() et al based on code review dm mpath: remove __pgpath_busy forward declaration, rename to pgpath_busy dm mpath: switch from 'unsigned' to 'bool' for flags where appropriate dm round robin: use percpu 'repeat_count' and 'current_path' dm path selector: remove 'repeat_count' return from .select_path hook ...

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)" * tag 'pm+acpi-4.6-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (182 commits) tools/power turbostat: bugfix: TDP MSRs print bits fixing tools/power turbostat: correct output for MSR_NHM_SNB_PKG_CST_CFG_CTL dump tools/power turbostat: call __cpuid() instead of __get_cpuid() tools/power turbostat: indicate SMX and SGX support tools/power turbostat: detect and work around syscall jitter tools/power turbostat: show GFX%rc6 tools/power turbostat: show GFXMHz tools/power turbostat: show IRQs per CPU tools/power turbostat: make fewer systems calls tools/power turbostat: fix compiler warnings tools/power turbostat: add --out option for saving output in a file tools/power turbostat: re-name "%Busy" field to "Busy%" tools/power turbostat: Intel Xeon x200: fix turbo-ratio decoding tools/power turbostat: Intel Xeon x200: fix erroneous bclk value tools/power turbostat: allow sub-sec intervals ACPI / APEI: ERST: Fixed leaked resources in erst_init ACPI / APEI: Fix leaked resources intel_pstate: Do not skip samples partially intel_pstate: Remove freq calculation from intel_pstate_calc_busy() intel_pstate: Move intel_pstate_calc_busy() into get_target_pstate_use_performance() ...
