  • 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

  • fff7fb0b2   lib/GCD.c: use binary GCD algorithm instead of Euclidean ... Browse Code »

    The binary GCD algorithm is based on the following facts:
    1. If a and b are all evens, then gcd(a,b) = 2 * gcd(a/2, b/2)
    2. If a is even and b is odd, then gcd(a,b) = gcd(a/2, b)
    3. If a and b are all odds, then gcd(a,b) = gcd((a-b)/2, b) = gcd((a+b)/2, b)

    Even on x86 machines with reasonable division hardware, the binary
    algorithm runs about 25% faster (80% the execution time) than the
    division-based Euclidian algorithm.

    On platforms like Alpha and ARMv6 where division is a function call to
    emulation code, it's even more significant.

    There are two variants of the code here, depending on whether a fast
    __ffs (find least significant set bit) instruction is available. This
    allows the unpredictable branches in the bit-at-a-time shifting loop to
    be eliminated.

    If fast __ffs is not available, the "even/odd" GCD variant is used.

    I use the following code to benchmark:

  • 786d35d45   Make most arch asm/module.h files use asm-generic/module.h ... Browse Code »

    Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela,
    ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version
    into asm-generic/module.h for all arches bar MIPS.

    Also, use the generic definition mod_arch_specific where possible.

    To this end, I've defined three new config bools:

    (*) HAVE_MOD_ARCH_SPECIFIC

    Arches define this if they don't want to use the empty generic
    mod_arch_specific struct.

    (*) MODULES_USE_ELF_RELA

    Arches define this if their modules can contain RELA records. This causes
    the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be
    defined by the arch rather than have the core emit an error message.

    (*) MODULES_USE_ELF_REL

    Arches define this if their modules can contain REL records. This causes
    the Elf_Rel mapping to be emitted and allows apply_relocate() to be
    defined by the arch rather than have the core emit an error message.

    Note that it is possible to allow both REL and RELA records: m68k and mips are
    two arches that do this.

    With this, some arch asm/module.h files can be deleted entirely and replaced
    with a generic-y marker in the arch Kbuild file.

    Additionally, I have removed the bits from m32r and score that handle the
    unsupported type of relocation record as that's now handled centrally.

  • 764e0da14   timers: Fixup the Kconfig consolidation fallout ... Browse Code »

    Sigh, I missed to check which architecture Kconfig files actually
    include the core Kconfig file. There are a few which did not. So we
    broke them.

    Instead of adding the includes to those, we are better off to move the
    include to init/Kconfig like we did already with irqs and others.

    This does not change anything for the architectures using the old
    style periodic timer mode. It just solves the build wreckage there.

    For those architectures which use the clock events infrastructure it
    moves the include of the core Kconfig file to "General setup" which is
    a way more logical place than having it at random locations specified
    by the architecture specific Kconfigs.

    lib: use generic pci_iomap on all architectures

    Many architectures don't want to pull in iomap.c,
    so they ended up duplicating pci_iomap from that file.
    That function isn't trivial, and we are going to modify it
    https://lkml.org/lkml/2011/11/14/183
    so the duplication hurts.

    This reduces the scope of the problem significantly,
    by moving pci_iomap to a separate file and
    referencing that from all architectures.

    43

    Now all ARCH_POPULATES_NODE_MAP archs select HAVE_MEBLOCK_NODE_MAP -
    there's no user of early_node_map[] left. Kill early_node_map[] and
    replace ARCH_POPULATES_NODE_MAP with HAVE_MEMBLOCK_NODE_MAP. Also,
    relocate for_each_mem_pfn_range() and helper from mm.h to memblock.h
    as page_alloc.c would no longer host an alternative implementation.

    This change is ultimately one to one mapping and shouldn't cause any
    observable difference; however, after the recent changes, there are
    some functions which now would fit memblock.c better than page_alloc.c
    and dependency on HAVE_MEMBLOCK_NODE_MAP instead of HAVE_MEMBLOCK
    doesn't make much sense on some of them. Further cleanups for
    functions inside HAVE_MEMBLOCK_NODE_MAP in mm.h would be nice.

    -v2: Fix compile bug introduced by mis-spelling
    CONFIG_HAVE_MEMBLOCK_NODE_MAP to CONFIG_MEMBLOCK_HAVE_NODE_MAP in
    mmzone.h. Reported by Stephen Rothwell.

    score used early_node_map[] just to prime free_area_init_nodes(). Now
    memblock can be used for the same purpose and early_node_map[] is
    scheduled to be dropped. Use memblock instead.

    By the previous style change, CONFIG_GENERIC_FIND_NEXT_BIT,
    CONFIG_GENERIC_FIND_BIT_LE, and CONFIG_GENERIC_FIND_LAST_BIT are not used
    to test for existence of find bitops anymore.

  • 592913ecb   time: Kill off CONFIG_GENERIC_TIME ... Browse Code »

    Now that all arches have been converted over to use generic time via
    clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME
    config option and simplify the generic code.
