       "Here are the core block changes for this merge window.  Not a lot of
        exciting stuff going on in this round, most of the changes have been
        on the driver side of things.  That pull request is coming next.  This
        pull request contains:
         - A set of fixes for chained bio handling from Christoph.
         - A tag bounds check for blk-mq from Hannes, ensuring that we don't
           do something stupid if a device reports an invalid tag value.
         - A set of fixes/updates for the CFQ IO scheduler from Jan Kara.
         - A set of blk-mq fixes from Keith, adding support for dynamic
           hardware queues, and fixing init of max_dev_sectors for stacking
         - A fix for the dynamic hw context from Ming.

      USB: uas: Reduce can_queue to MAX_CMNDS · 55ff8cfb
      Hans de Goede authored
      The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
      are shared between luns, so there is no need to claim that we can_queue
      some random large number.
      Not claiming that we can_queue 65536 commands, fixes the uas driver
      failing to initialize while allocating the tag map with a "Page allocation
      failure (order 7)" error on systems which have been running for a while
      and thus have fragmented memory.

      usb/core: usb_alloc_dev(): fix setting of ->portnum · 7222c832
      Nicolai Stange authored
      With commit 69bec725 ("USB: core: let USB device know device node"),
      the port1 argument of usb_alloc_dev() gets overwritten as follows:
        ... usb_alloc_dev(..., unsigned port1)
          if (!parent->parent) {
            port1 = usb_hcd_find_raw_port_number(..., port1);
      Later on, this now overwritten port1 gets assigned to ->portnum:
        dev->portnum = port1;
      However, since xhci_find_raw_port_number() isn't idempotent, the
      aforementioned commit causes a number of KASAN splats like the following:

      The iowarrior driver expects at least one valid endpoint.  If given

      it will crash in the probe function.  Ensure there is at least

       "Here is the big staging driver pull request for 4.6-rc1.
        Lots of little things here, over 1600 patches or so.  Notable is all
        of the good Lustre work happening, those developers have finally woken
        up and are cleaning up their code greatly.  The Outreachy intern
        application process is also happening, which brought in another 400 or
        so patches.  Full details are in the very long shortlog.
        All of these have been in linux-next with no reported issues"

       "The most notable item is addition of support for Synaptics RMI4
        protocol which is native protocol for all current Synaptics devices
        (touchscreens, touchpads).  In later releases we'll switch devices
        using HID and PS/2 protocol emulation to RMI4.
        You will also get:
         - BYD PS/2 touchpad protocol support for psmouse
         - MELFAS MIP4 Touchscreen driver
         - rotary encoder was moved away from legacy platform data and to
           generic device properties API, devm_* API, and can now handle
           encoders using more than 2 GPIOs
         - Cypress touchpad driver was switched to devm_* API and device

      Merge tag 'gpio-v4.6-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio · 1a46712a
      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
         - 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.
         - Bjorn Helgaas removed a whole slew of per-architecture <asm/gpio.h>
           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
         - 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.
         - 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
         - 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

       "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
