  • 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

  • f197d75fc   scripts/gdb: provide linux constants ... Browse Code »

    Some macro's and defines are needed when parsing memory, and without
    compiling the kernel as -g3 they are not available in the debug-symbols.

    We use the pre-processor here to extract constants to a dedicated module
    for the linux debugger extensions

    Top level Kbuild is used to call in and generate the constants file,
    while maintaining dependencies on autogenerated files in
    include/generated

    This breaks MN10300 arch as this changes many instances of instructions
    similar to the following:

    which represents an immediate value load into:

    MOV (number),D0

    which the assembler then interprets as a load from absolute address.

  • 3234282f3   x86, asm: Fix CFI macro invocations to deal with shortcomings in gas ... Browse Code »

    gas prior to (perhaps) 2.16.90 has problems with passing non-
    parenthesized expressions containing spaces to macros. Spaces, however,
    get inserted by cpp between any macro expanding to a number and a
    subsequent + or -. For the +, current x86 gas then removes the space
    again (future gas may not do so), but for the - the space gets retained
    and is then considered a separator between macro arguments.

    Fix the respective definitions for both the - and + cases, so that they
    neither contain spaces nor make cpp insert any (the latter by adding
    seemingly redundant parentheses).

    Commit 7d3cc8b tried to keep bounds.h and asm-offsets.h during make

    $(targets) and $(always) and thus removed automatically. Introduce a new

    We check the precense of include/asm-$ARCH by checking

    Mips needs this feature to preserve the comments that are in

    Arch code already has a way to export constants calculated to the preprocessor

  • c53aeca05   kbuild: complain about missing system calls ... Browse Code »

    Most system calls seems to get added to i386 first. This patch
    automatically generates a warning for any new system call which is
    implemented on i386 but not the architecture currently being compiled.
    On PowerPC at the moment, for example, it results in these warnings:
    init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
    init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
    init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented

    The file scripts/checksyscalls.sh list a number of legacy system calls
    that are ignored because they only makes sense on i386 systems.

    Other contributors to this patch are Russell King
    and Stéphane Jourdois

    Building asm-offsets.h has been moved to a seperate Kbuild file
    located in the top-level directory. This allow us to share the
    functionality across the architectures.

    The old rules in architecture specific Makefiles will die
    in subsequent patches.

    Furhtermore the usual kbuild dependency tracking is now used
    when deciding to rebuild asm-offsets.s. So we no longer risk
    to fail a rebuild caused by asm-offsets.c dependencies being touched.

    With this common rule-set we now force the same name across
    all architectures. Following patches will fix the rest.
