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.

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 ...

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 ...

Pull VFIO updates from Alex Williamson: "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" * 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
