  • 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

    We are planning to share more code between different NAND based
    devices (SPI NAND, OneNAND and raw NANDs), but before doing that
    we need to move the existing include/linux/mtd/nand.h file into
    include/linux/mtd/rawnand.h so we can later create a nand.h header
    containing all common structure and function prototypes.

  • 2d4d3b5d4   blackfin: make-bf561/coreb.c explicitly non-modular ... Browse Code »

    The Kconfig currently controlling compilation of this code is:

    config BF561_COREB
    bool "Enable Core B loader"

    ...meaning that it currently is not being built as a module by anyone.

    Lets remove the modular code that is essentially orphaned, so that
    when reading the driver there is no doubt it is builtin-only.

    Since module_misc_device translates to device_initcall in the non-modular
    case, the init ordering remains unchanged with this commit.

    We also delete the MODULE_LICENSE tag etc. since all that information
    was (or is now) contained at the top of the file in the comments.

  • ca75d601b   miscdevice: Add helper macro for misc device boilerplate ... Browse Code »

    Many modules call misc_register and misc_deregister in its module init
    and exit methods without any additional code. This ends up being
    boilerplate. This patch adds helper macro module_misc_device(), that
    replaces module_init()/ module_exit() with template functions.

    This patch also converts drivers to use new macro.

    Change since v1:
    Add device.h include in miscdevice.h as module_driver macro was not
    available from other include files in some architectures.

  • 2fb04fdf3   net: smc91x: fix SMC accesses ... Browse Code »

    Commit b70661c70830 ("net: smc91x: use run-time configuration on all ARM
    machines") broke some ARM platforms through several mistakes. Firstly,
    the access size must correspond to the following rule:

    (a) at least one of 16-bit or 8-bit access size must be supported
    (b) 32-bit accesses are optional, and may be enabled in addition to
    the above.

    Secondly, it provides no emulation of 16-bit accesses, instead blindly
    making 16-bit accesses even when the platform specifies that only 8-bit
    is supported.

    Reorganise smc91x.h so we can make use of the existing 16-bit access
    emulation already provided - if 16-bit accesses are supported, use
    16-bit accesses directly, otherwise if 8-bit accesses are supported,
    use the provided 16-bit access emulation. If neither, BUG(). This
    exactly reflects the driver behaviour prior to the commit being fixed.

    Since the conversion incorrectly cut down the available access sizes on
    several platforms, we also need to go through every platform and fix up
    the overly-restrictive access size: Arnd assumed that if a platform can
    perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
    size needed to be specified - not so, all available access sizes must
    be specified.

    This likely fixes some performance regressions in doing this: if a
    platform does not support 8-bit accesses, 8-bit accesses have been
    emulated by performing a 16-bit read-modify-write access.

    Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
    accesses, which was broken by the original commit.

    Implement FETCH-OP atomic primitives, these are very similar to the
    existing OP-RETURN primitives we already have, except they return the
    value of the atomic variable _before_ modification.

    This is especially useful for irreversible operations -- such as
    bitops (because it becomes impossible to reconstruct the state prior
    to modification).

    Pull MTD updates from Brian Norris:
    "Generic MTD:

    - populate the MTD device 'of_node' field (and get a proper 'of_node'
    symlink in sysfs)

    This yielded some new helper functions, and changes across a
    variety of drivers

    - partitioning cleanups, to prepare for better device-tree based
    partitioning in the future

    Eliminate a lot of boilerplate for drivers that want to use
    OF-based partition parsing

    The DT bindings for this didn't settle yet, so most non-cleanup
    portions are deferred for a future release

    NAND:

    - embed a struct mtd_info inside struct nand_chip

    This is really long overdue; too many drivers have to do the same
    silly boilerplate to allocate and link up two "independent"
    structs, when in fact, everyone is assuming there is an exact 1:1
    relationship between a NAND chips struct and its underlying MTD.
    This aids improved helpers and should make certain abstractions
    easier in the future.

    Also causes a lot of churn, helped along by some automated code
    transformations

    - add more core support for detecting (and "correcting") bitflips in
    erased pages; requires opt-in by drivers, but at least we kill a
    few bad implementations and hopefully stave off future ones

    - pxa3xx_nand: cleanups, a few fixes, and PM improvements

    - new JZ4780 NAND driver

    SPI NOR:

    - provide default erase function, for controllers that just want to
    send the SECTOR_ERASE command directly

    - fix some module auto-loading issues with device tree
    ("jedec,spi-nor")

    - error handling fixes

    - new Mediatek QSPI flash driver

    Other:

    - cfi: force valid geometry Kconfig (finally!)

    This one used to trip up randconfigs occasionally, since bots
    aren't deterred by big scary "advanced configuration" menus

    More? Probably. See the commit logs"

  • b5dcee225   [media] include/media: split I2C headers from V4L2 core ... Browse Code »

    Currently, include/media is messy, as it contains both the V4L2 core
    headers and some driver-specific headers on the same place. That makes
    harder to identify what core headers should be documented and what
    headers belong to I2C drivers that are included only by bridge/main
    drivers that would require the functions provided by them.

    Let's move those i2c specific files to its own subdirectory.

    The files to move were produced via the following script:
    mkdir include/media/i2c
    (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
    (cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
    for i in include/media/*.h; do n=`basename $i`; (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done

    And the references corrected via this script:
    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="i2c/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
    for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
    n=`basename $j`
    git grep -l $n
    done
    done|sort|uniq >files && (
    echo "Handling files..." >&2;
    echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
    (
    cd include/$MAIN_DIR;
    for j in $DIRS; do
    for i in $(ls $j); do
    echo "perl -ne 's,(include [\\\"\\&2;
    echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
    (
    cd include/$MAIN_DIR;
    for j in $DIRS; do
    for i in $(ls $j); do
    echo " perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
    done;
    done;
    echo "cat > a && mv a \$i; done"
    );
    ) >script && . ./script

  • 13dff62d8   blackfin: delete __cpuinit usage from all blackfin files ... Browse Code »

    The __cpuinit type of throwaway sections might have made sense
    some time ago when RAM was more constrained, but now the savings
    do not offset the cost and complications. For example, the fix in
    commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
    is a good example of the nasty type of bugs that can be created
    with improper use of the various __init prefixes.

    After a discussion on LKML[1] it was decided that cpuinit should go
    the way of devinit and be phased out. Once all the users are gone,
    we can then finally remove the macros themselves from linux/init.h.

    Note that some harmless section mismatch warnings may result, since
    notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
    are flagged as __cpuinit -- so if we remove the __cpuinit from
    arch specific callers, we will also get section mismatch warnings.
    As an intermediate step, we intend to turn the linux/init.h cpuinit
    content into no-ops as early as possible, since that will get rid
    of these warnings. In any case, they are temporary and harmless.

    This removes all the arch/blackfin uses of the __cpuinit macros from
    all C files. Currently blackfin does not have any __CPUINIT used in
    assembly files.
