  • b24413180   License cleanup: add SPDX GPL-2.0 license identifier to files with no license ... Browse Code »

    Many source files in the tree are missing licensing information, which
    makes it harder for compliance tools to determine the correct license.

    By default all files without license information are under the default
    license of the kernel, which is GPL version 2.

    Update the files which contain no license information with the 'GPL-2.0'
    SPDX license identifier. The SPDX identifier is a legally binding
    shorthand, which can be used instead of the full boiler plate text.

    This patch is based on work done by Thomas Gleixner and Kate Stewart and
    Philippe Ombredanne.

    How this work was done:

    Patches were generated and checked against linux-4.14-rc6 for a subset of
    the use cases:
    - file had no licensing information it it.
    - file was a */uapi/* one with no licensing information in it,
    - file was a */uapi/* one with existing licensing information,

    Further patches will be generated in subsequent months to fix up cases
    where non-standard license headers were used, and references to license
    had to be inferred by heuristics based on keywords.

    The analysis to determine which SPDX License Identifier to be applied to
    a file was done in a spreadsheet of side by side results from of the
    output of two independent scanners (ScanCode & Windriver) producing SPDX
    tag:value files created by Philippe Ombredanne. Philippe prepared the
    base worksheet, and did an initial spot review of a few 1000 files.

    The 4.13 kernel was the starting point of the analysis with 60,537 files
    assessed. Kate Stewart did a file by file comparison of the scanner
    results in the spreadsheet to determine which SPDX license identifier(s)
    to be applied to the file. She confirmed any determination that was not
    immediately clear with lawyers working with the Linux Foundation.

    Criteria used to select files for SPDX license identifier tagging was:
    - Files considered eligible had to be source code files.
    - Make and config files were included as candidates if they contained >5
    lines of source
    - File already had some variant of a license header in it (even if

  • 0f4630f37   gpio: generic: factor into gpio_chip struct ... Browse Code »

    The separate struct bgpio_chip has been a pain to handle, both
    by being confusingly similar in name to struct gpio_chip and
    for being contained inside a struct so that struct gpio_chip
    is contained in a struct contained in a struct, making several
    steps of dereferencing necessary.

    Make things simpler: include the fields directly into
    , #ifdef:ed for CONFIG_GENERIC_GPIO, and
    get rid of the altogether. Prefix
    some of the member variables with bgpio_* and add proper
    kerneldoc while we're at it.

    Modify all users to handle the change and use a struct
    gpio_chip directly. And while we're at it: replace all
    container_of() dereferencing by gpiochip_get_data() and
    registering the gpio_chip with gpiochip_add_data().

    Pull libnvdimm updates from Dan Williams:
    "This update has successfully completed a 0day-kbuild run and has
    appeared in a linux-next release. The changes outside of the typical
    drivers/nvdimm/ and drivers/acpi/nfit.[ch] paths are related to the
    removal of IORESOURCE_CACHEABLE, the introduction of memremap(), and
    the introduction of ZONE_DEVICE + devm_memremap_pages().

    Summary:

    - Introduce ZONE_DEVICE and devm_memremap_pages() as a generic
    mechanism for adding device-driver-discovered memory regions to the
    kernel's direct map.

    This facility is used by the pmem driver to enable pfn_to_page()
    operations on the page frames returned by DAX ('direct_access' in
    'struct block_device_operations').

    For now, the 'memmap' allocation for these "device" pages comes
    from "System RAM". Support for allocating the memmap from device
    memory will arrive in a later kernel.

    - Introduce memremap() to replace usages of ioremap_cache() and
    ioremap_wt(). memremap() drops the __iomem annotation for these
    mappings to memory that do not have i/o side effects. The
    replacement of ioremap_cache() with memremap() is limited to the
    pmem driver to ease merging the api change in v4.3.

    Completion of the conversion is targeted for v4.4.

    - Similar to the usage of memcpy_to_pmem() + wmb_pmem() in the pmem
    driver, update the VFS DAX implementation and PMEM api to provide
    persistence guarantees for kernel operations on a DAX mapping.

    - Convert the ACPI NFIT 'BLK' driver to map the block apertures as
    cacheable to improve performance.

    - Miscellaneous updates and fixes to libnvdimm including support for
    issuing "address range scrub" commands, clarifying the optimal
    'sector size' of pmem devices, a clarification of the usage of the
    ACPI '_STA' (status) property for DIMM devices, and other minor
    fixes"

  • 92b19ff50   cleanup IORESOURCE_CACHEABLE vs ioremap() ... Browse Code »

    Quoting Arnd:
    I was thinking the opposite approach and basically removing all uses
    of IORESOURCE_CACHEABLE from the kernel. There are only a handful of
    them.and we can probably replace them all with hardcoded
    ioremap_cached() calls in the cases they are actually useful.

    All existing usages of IORESOURCE_CACHEABLE call ioremap() instead of
    ioremap_nocache() if the resource is cacheable, however ioremap() is
    uncached by default. Clearly none of the existing usages care about the
    cacheability. Particularly devm_ioremap_resource() never worked as
    advertised since it always fell back to plain ioremap().

    Clean this up as the new direction we want is to convert
    ioremap_() usages to memremap(..., flags).

    Pull ARM SoC cleanups from Olof Johansson:
    "This merge window brings a good size of cleanups on various platforms.

    - Removal of Samsung s5pc100 and s5p64xx platforms. Both of these

    around nobody showed interest in keeping them around. If needed,
    they could be resurrected in the future but it's more likely that
    we would prefer reintroduction of them as DT and
    multiplatform-enabled platforms instead.

    - OMAP4 controller code register define diet. They defined a lot of
    registers that were never actually used, etc.

    - Move of some of the Tegra platform code (PMC, APBIO, fuse,
    powergate) to drivers/soc so it can be shared with 64-bit code.
    This also converts them over to traditional driver models where
    possible.

    - Removal of legacy gpio-samsung driver, since the last users have
    been removed (moved to pinctrl)

    This cleanup series gets rid of for platforms not using
    ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
    387798b (ARM: initial multiplatform support).)

    To make this work some code out of arch/arm needed to be adapted. The
    respective changes got acks by their maintainers to be taken via armsoc
    (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).

    Compared to the previous pull request there was another patch added that
    fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
    squash this fix into the original commit to save him from the need to

    While isn't used for multi-platform builds since long it
    still is for "normal" builds. As the previous patches fix all sites to
    not make use of this per-platform file, it can go now for good also for
    platforms that are not (yet) converted to multi-platform.

    While at it there are no users of CLOCK_TICK_RATE any more, so also drop
    the dummy #define.
