  • 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

  • e32465429   ARM: use "depends on" for SoC configs instead of "if" after prompt ... Browse Code »

    Many ARM sub-architectures use prompts followed by "if" conditional,
    but it is wrong.

    Please notice the difference between

    config ARCH_FOO
    bool "Foo SoCs" if ARCH_MULTI_V7

    and

    config ARCH_FOO
    bool "Foo SoCs"
    depends on ARCH_MULTI_V7

    These two are *not* equivalent!

    In the former statement, it is not ARCH_FOO, but its prompt that
    depends on ARCH_MULTI_V7. So, it is completely valid that ARCH_FOO
    is selected by another, but ARCH_MULTI_V7 is still disabled. As it is
    not unmet dependency, Kconfig never warns. This is probably not what
    you want.

    The former should be used only when you need to do so, and you really
    understand what you are doing. (In most cases, it should be wrong!)

    For enabling/disabling sub-architectures, the latter is always correct.

    As a good side effect, this commit fixes some entries over 80 columns
    (mach-imx, mach-integrator, mach-mbevu).

    [Arnd: I note that there is not really a bug here, according to
    the discussion that followed, but I can see value in being consistent
    and in making the lines shorter]

  • 75305275a   ARM: use const and __initconst for smp_operations ... Browse Code »

    These smp_operations structures are not over-written, so add "const"
    qualifier and replace __initdata with __initconst.

    Also, add "static" where it is possible.
