      mm: Silence vmap() allocation failures based on caller gfp_flags · 03497d76
      Florian Fainelli authored
      If the caller has set __GFP_NOWARN don't print the following message:
      vmap allocation for size 15736832 failed: use vmalloc=<size> to increase
      size.
      
      This can happen with the ARM/Linux or ARM64/Linux module loader built
      with CONFIG_ARM{,64}_MODULE_PLTS=y which does a first attempt at loading
      a large module from module space, then falls back to vmalloc space.

        It has been long since the introduction of uapi directories, but the

        in header-y are exported whether they exist in uapi directories or

        All (and only) headers under uapi directories are now exported. The

      Linus Torvalds authored
      Pull hw lockdown support from David Howells:
       "Annotation of module parameters that configure hardware resources
        including ioports, iomem addresses, irq lines and dma channels.
      
        This allows a future patch to prohibit the use of such module
        parameters to prevent that hardware from being abused to gain access
        to the running kernel image as part of locking the kernel down under
        UEFI secure boot conditions.
      
        Annotations are made by changing:
      
              module_param(n, t, p)
              module_param_named(n, v, t, p)
              module_param_array(n, t, m, p)
      
        to:
      
              module_param_hw(n, t, hwtype, p)
              module_param_hw_named(n, v, t, hwtype, p)
              module_param_hw_array(n, t, hwtype, m, p)
      
        where the module parameter refers to a hardware setting
      
        hwtype specifies the type of the resource being configured. This can
        be one of:
      
              ioport          Module parameter configures an I/O port
              iomem           Module parameter configures an I/O mem address
              ioport_or_iomem Module parameter could be either (runtime set)
              irq             Module parameter configures an I/O port
              dma             Module parameter configures a DMA channel
              dma_addr        Module parameter configures a DMA buffer address
              other           Module parameter configures some other value
      
        Note that the hwtype is compile checked, but not currently stored (the
        lockdown code probably won't require it). It is, however, there for
        future use.
      
        A bonus is that the hwtype can also be used for grepping.
      
        The intention is for the kernel to ignore or reject attempts to set
        annotated module parameters if lockdown is enabled. This applies to
        options passed on the boot command line, passed to insmod/modprobe or
        direct twiddling in /sys/module/ parameter files.
      
        The module initialisation then needs to handle the parameter not being
        set, by (1) giving an error, (2) probing for a value or (3) using a
        reasonable default.
      
        What I can't do is just reject a module out of hand because it may
        take a hardware setting in the module parameters. Some important
        modules, some ipmi stuff for instance, both probe for hardware and
        allow hardware to be manually specified; if the driver is aborts with
        any error, you don't get any ipmi hardware.
      
        Further, trying to do this entirely in the module initialisation code
        doesn't protect against sysfs twiddling.
      
        [!] Note that in and of itself, this series of patches should have no
            effect on the the size of the kernel or code execution - that is
            left to a patch in the next series to effect. It does mark
            annotated kernel parameters with a KERNEL_PARAM_FL_HWPARAM flag in
            an already existing field"

      Pull clk updates from Stephen Boyd:
       "Sort of on the quieter side this time, which is probably due more to
        me not catching up as quickly on patch review than anything else.
        Overall it seems normal though, a few small changes to the core,
        mostly small non-critical fixes here and there as well as driver
        updates for new and existing hardware support.
      
        The biggest things are the TI clk driver rework to lay the groundwork
        for clkctrl support in the next merge window and the AmLogic
        audio/graphics clk support.
      
        Core:
         - clk_possible_parents debugfs file so we know which parents a clk
           could possibly have
         - Fix to make clk rate change notifiers stop on the first failure
           instead of continuing
      
        New Drivers:
         - Mediatek MT6797 SoCs
         - hi655x PMIC clks
         - AmLogic Meson SoC i2s and spdif audio clks and Mali graphics clks
         - Allwinner H5 SoCs and PRCM hardware
      
        Updates:
         - Nvidia Tegra T210 cleanups and non-critical fixes
         - TI OMAP cleanups in preparation for clkctrl support
         - trivial fixes like kcalloc(), devm_* conversions, and seq_puts()
         - ZTE zx296718 SoC VGA clks
         - Rockchip clk-ids, fixups, and rename of rk1108 to rv1108
         - IDT VersaClock 5P49V5935 support
         - Renesas R-Car H3 and M3-W IMR clks and ES2.0 rev of R-Car H3
           support"

      In error cases, lgp->lg_layout_type may be out of bounds; so we

      This was seen to crash nfsd threads when the server receives a LAYOUTGET

      GETDEVICEINFO has the same problem.

      Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
       "This introduces a generic TEE framework in the kernel, to handle
        trusted environemtns (security coprocessor or software implementations
        such as OP-TEE/TrustZone). I'm sending it separately from the other
        arm-soc driver changes to give it a little more visibility, once the
        subsystem is merged, we will likely keep this in the arm₋soc drivers
        branch or have the maintainers submit pull requests directly,
        depending on the patch volume.
      
        I have reviewed earlier versions in the past, and have reviewed the
        latest version in person during Linaro Connect BUD17.
      
        Here is my overall assessment of the subsystem:
      
         - There is clearly demand for this, both for the generic
           infrastructure and the specific OP-TEE implementation.
      
         - The code has gone through a large number of reviews, and the review
           comments have all been addressed, but the reviews were not coming
           up with serious issues any more and nobody volunteered to vouch for
           the quality.
      
         - The user space ioctl interface is sufficient to work with the
           OP-TEE driver, and it should in principle work with other TEE
           implementations that follow the GlobalPlatform[1] standards, but it
           might need to be extended in minor ways depending on specific
           requirements of future TEE implementations
      
         - The main downside of the API to me is how the user space is tied to
           the TEE implementation in hardware or firmware, but uses a generic
           way to communicate with it. This seems to be an inherent problem
           with what it is trying to do, and I could not come up with any
           better solution than what is implemented here.

      uapi: export all arch specifics directories · 61562f98
      Nicolas Dichtel authored
      This patch removes the need of subdir-y. Now all files/directories under
      arch/<arch>/include/uapi/ are exported.
      
      The only change for userland is the layout of the command 'make
      headers_install_all': directories asm-<arch> are replaced by arch-<arch>/.
      Those new directories contains all files/directories of the specified arch.
      
      Note that only cris and tile have more directories than only asm:
       - arch-v[10|32] for cris;
       - arch for tile.

      uapi: export all headers under uapi directories · fcc8487d
      Nicolas Dichtel authored
      Regularly, when a new header is created in include/uapi/, the developer
      forgets to add it in the corresponding Kbuild file. This error is usually
      detected after the release is out.
      
      In fact, all headers under uapi directories should be exported, thus it's
      useless to have an exhaustive list.

      Makefile.headersinst: cleanup input files · 7c025b2a
      Nicolas Dichtel authored
      After the last three patches, all exported headers are under uapi/, thus
      input-files2 are not needed anymore.
      The side effect is that input-files1-name is exactly header-y.
      
      Note also that input-files3-name is genhdr-y.
