  • d503ac531   kbuild: rename LDFLAGS to KBUILD_LDFLAGS ... Browse Code »

    Commit a0f97e06a43c ("kbuild: enable 'make CFLAGS=...' to add
    additional options to CC") renamed CFLAGS to KBUILD_CFLAGS.

    Commit 222d394d30e7 ("kbuild: enable 'make AFLAGS=...' to add
    additional options to AS") renamed AFLAGS to KBUILD_AFLAGS.

    Commit 06c5040cdb13 ("kbuild: enable 'make CPPFLAGS=...' to add
    additional options to CPP") renamed CPPFLAGS to KBUILD_CPPFLAGS.

    For some reason, LDFLAGS was not renamed.

    Using a well-known variable like LDFLAGS may result in accidental
    override of the variable.

    Kbuild generally uses KBUILD_ prefixed variables for the internally
    appended options, so here is one more conversion to sanitize the
    naming convention.

    I did not touch Makefiles under tools/ since the tools build system
    is a different world.

  • 5c93316c8   mips: unify prom_putchar() declarations ... Browse Code »

    prom_putchar() is used centrally in early printk infrastructure therefore
    at least MIPS should agree on the function return type.

    [paul.burton@mips.com:
    - Include linux/types.h in asm/setup.h to gain the bool typedef before
    we start include asm/setup.h elsewhere.
    - Include asm/setup.h in all files that use or define prom_putchar().
    - Also standardise on signed rather than unsigned char argument.]

  • f06e7aa47   MIPS: Convert update_persistent_clock() to update_persistent_clock64() ... Browse Code »

    Since struct timespec is not y2038 safe on 32bit machines, this patch
    converts update_persistent_clock() to update_persistent_clock64() using
    struct timespec64.

    The rtc_mips_set_time() and rtc_mips_set_mmss() interfaces were using
    'unsigned long' type that is not y2038 safe on 32bit machines, moreover
    there is only one platform implementing rtc_mips_set_time() and two
    platforms implementing rtc_mips_set_mmss(), so we can just make them each
    implement update_persistent_clock64() directly, to get that helper out
    of the common mips code by removing rtc_mips_set_time() and
    rtc_mips_set_mmss() interfaces.

  • e99e88a9d   treewide: setup_timer() -> timer_setup() ... Browse Code »

    This converts all remaining cases of the old setup_timer() API into using
    timer_setup(), where the callback argument is the structure already
    holding the struct timer_list. These should have no behavioral changes,
    since they just change which pointer is passed into the callback with
    the same available pointers after conversion. It handles the following
    examples, in addition to some other variations.

    Casting from unsigned long:

    void my_callback(unsigned long data)
    {
    struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

    and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

    become:

    void my_callback(struct timer_list *t)
    {
    struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

    Direct function assignments:

    void my_callback(unsigned long data)
    {
    struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

    have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
    struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

    And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

    have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

    The conversion is done with the following Coccinelle script:

    spatch --very-quiet --all-includes --include-headers \
    -I ./arch/x86/include -I ./arch/x86/include/generated \

  • 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

  • 26dd3e4ff   MIPS: Audit and remove any unnecessary uses of module.h ... Browse Code »

    Historically a lot of these existed because we did not have
    a distinction between what was modular code and what was providing
    support to modules via EXPORT_SYMBOL and friends. That changed
    when we forked out support for the latter into the export.h file.

    This means we should be able to reduce the usage of module.h
    in code that is obj-y Makefile or bool Kconfig. In the case of
    some code where it is modular, we can extend that to also include
    files that are building basic support functionality but not related
    to loading or registering the final module; such files also have
    no need whatsoever for module.h

    The advantage in removing such instances is that module.h itself
    sources about 15 other headers; adding significantly to what we feed
    cpp, and it can obscure what headers we are effectively using.

    Since module.h might have been the implicit source for init.h
    (for __init) and for export.h (for EXPORT_SYMBOL) we consider each
    instance for the presence of either and replace/add as needed.

    Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

    Build coverage of all the mips defconfigs revealed the module.h
    header was masking a couple of implicit include instances, so
    we add the appropriate headers there.

  • 2ee966320   time: Add y2038 safe read_persistent_clock64() ... Browse Code »

    As part of addressing in-kernel y2038 issues, this patch adds
    read_persistent_clock64() and replaces all the call sites of
    read_persistent_clock() with this function. This is a __weak
    implementation, which simply calls the existing y2038 unsafe
    read_persistent_clock().

    This allows architecture specific implementations to be
    converted independently, and eventually the y2038 unsafe
    read_persistent_clock() can be removed after all its
    architecture specific implementations have been converted to
    read_persistent_clock64().

  • 3185557d1   MIPS: Refactor load/entry address calculations ... Browse Code »

    The vmlinux load address and entry address is calculated in multiple
    places:
    - arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or
    defined by the platform) and passes it to
    arch/mips/boot/compressed/Makefile.
    - arch/mips/boot/compressed/Makefile calculates kernel entry using nm.
    - arch/mips/lasat/image/Makefile calculates both load and entry address
    using nm.

    Lets combine these in the main Makefile and then pass them as Make
    parameters to each of the three boot image Makefiles (in boot/,
    boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use
    them, but will soon need to for U-Boot image targets.

    The existing load-y definition is used in preference to calculating the
    load address using nm.

    o Lantiq and BCM47XX platform have a few improvements and bug fixes.

    o MIPS has sent a few patches that get the kernel ready for the
    upcoming microMIPS support.

    o The rest of the series is made up of small bug fixes and cleanups
    that relate to various parts of the MIPS code. The biggy in there is
    a whitespace cleanup. After I was sent another set of whitespace
    cleanup patches I decided it was the time to clean the whitespace
    "issues" for once and and that touches many files below arch/mips/.
