      exec_drive_taskfile() checks for dma mapping errors by comparison
      returned address with zero, while pci_dma_mapping_error() should be used.

      lightnvm: do not load L2P table if not supported · 29fd20b8
      Javier González authored
      An Open-Channel SSD can work on two modes: (i) hybrid mode, where the
      L2P table is maintained both by the host and by the device; and (ii)
      full host-based, where the L2P table is uniquely maintained by the host.
      
      In the advent of a new target implementing the full host-based mode, do
      not assume that the L2P table must be loaded on the generic media
      manager; check device properties loaded on the identify command instead.

      lightnvm: do not reserve lun on l2p loading · 719b5917
      Javier González authored
      When the l2p table is loaded, addresses are checked for the lun they
      belong to and luns are reserved accordingly. This assumes that metadata
      is being stored in the backend device to recover the previous target
      configuration. Since this is not yet implemented, this check collides
      with some of the core initialization (e.g., sysblock initialization when
      a page is formed by several sectors).
      
      We take this check out and for now rely on that the right target will be
      created instead. When metadata is stored to recover a target, this check
      will come natural as part of the recovery strategy.

      Matias Bjorling authored
      PPAs sent to device is separately acknowledge in a 64bit status
      variable. The status is stored in DW0 and DW1 of the completion queue
      entry. Store this status inside the nvm_rq for further processing.
      
      This can later be used to implement retry techniques for failed writes
      and reads.

      lightnvm: specify target's logical address area · 4c9dacb8
      Wenwei Tao authored
      We can create more than one target on a lightnvm
      device by specifying its begin lun and end lun.
      
      But only specify the physical address area is not
      enough, we need to get the corresponding non-
      intersection logical address area division from
      the backend device's logcial address space.
      Otherwise the targets on the device might use
      the same logical addresses cause incorrect
      information in the device's l2p table.

      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: cdc-acm: more sanity checking · 8835ba4a
      Oliver Neukum authored
      An attack has become available which pretends to be a quirky
      device circumventing normal sanity checks and crashes the kernel
      by an insufficient number of interfaces. This patch adds a check
      to the code path for quirky devices.

      USB: usb_driver_claim_interface: add sanity checking · 0b818e39
      Oliver Neukum authored
      Attacks that trick drivers into passing a NULL pointer
      to usb_driver_claim_interface() using forged descriptors are
      known. This thwarts them by sanity checking.

      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:

      Fix this by not overwriting the port1 argument in usb_alloc_dev(), but
      storing the raw port number as required by OF in an additional variable,
      raw_port.

      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:

      Linus Torvalds authored
      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

         - Code clean-ups"
