  • a7f7f6248   treewide: replace '---help---' in Kconfig files with 'help' ... Browse Code »

    Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over
    '---help---'"), the number of '---help---' has been gradually
    decreasing, but there are still more than 2400 instances.

    This commit finishes the conversion. While I touched the lines,
    I also fixed the indentation.

    There are a variety of indentation styles found.

    a) 4 spaces + '---help---'
    b) 7 spaces + '---help---'
    c) 8 spaces + '---help---'
    d) 1 space + 1 tab + '---help---'
    e) 1 tab + '---help---' (correct indentation)
    f) 1 tab + 1 space + '---help---'
    g) 1 tab + 2 spaces + '---help---'

    In order to convert all of them to 1 tab + 'help', I ran the
    following commend:

    $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

  • e31cf2f4c   mm: don't include asm/pgtable.h if linux/mm.h is already included ... Browse Code »

    Patch series "mm: consolidate definitions of page table accessors", v2.

    The low level page table accessors (pXY_index(), pXY_offset()) are
    duplicated across all architectures and sometimes more than once. For
    instance, we have 31 definition of pgd_offset() for 25 supported
    architectures.

    Most of these definitions are actually identical and typically it boils
    down to, e.g.

    static inline unsigned long pmd_index(unsigned long address)
    {
    return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
    }

    static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
    {
    return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
    }

    These definitions can be shared among 90% of the arches provided
    XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.

    For architectures that really need a custom version there is always
    possibility to override the generic version with the usual ifdefs magic.

    These patches introduce include/linux/pgtable.h that replaces
    include/asm-generic/pgtable.h and add the definitions of the page table
    accessors to the new header.

    This patch (of 12):

    The linux/mm.h header includes to allow inlining of the
    functions involving page table manipulations, e.g. pte_alloc() and
    pmd_alloc(). So, there is no point to explicitly include
    in the files that include .

    The include statements in such cases are remove with a simple loop:

    for f in $(git grep -l "include ") ; do
    sed -i -e '/include / d' $f
    done

  • 5926e7e16   ARM: 8965/2: footbridge: replace setup_irq() by request_irq() ... Browse Code »

    request_irq() is preferred over setup_irq(). Invocations of setup_irq()
    occur after memory allocators are ready.

    Per tglx[1], setup_irq() existed in olden days when allocators were not
    ready by the time early interrupts were initialized.

    Hence replace setup_irq() by request_irq().

  • 6396bb221   treewide: kzalloc() -> kcalloc() ... Browse Code »

    The kzalloc() function has a 2-factor argument form, kcalloc(). This
    patch replaces cases of:

    kzalloc(a * b, gfp)

    with:
    kcalloc(a * b, gfp)

    as well as handling cases of:

    kzalloc(a * b * c, gfp)

    with:

    kzalloc(array3_size(a, b, c), gfp)

    as it's slightly less ugly than:

    kzalloc_array(array_size(a, b), c, gfp)

    This does, however, attempt to ignore constant size factors like:

    kzalloc(4 * 1024, gfp)

    though any constants defined via macros get caught up in the conversion.

    Any factors with a sizeof() of "unsigned char", "char", and "u8" were
    dropped, since they're redundant.

    The Coccinelle script used for this was:

    Pull timer updates from Thomas Gleixner:
    "Yet another big pile of changes:

    - More year 2038 work from Arnd slowly reaching the point where we
    need to think about the syscalls themself.

    - A new timer function which allows to conditionally (re)arm a timer
    only when it's either not running or the new expiry time is sooner
    than the armed expiry time. This allows to use a single timer for
    multiple timeout requirements w/o caring about the first expiry
    time at the call site.

    - A new NMI safe accessor to clock real time for the printk timestamp
    work. Can be used by tracing, perf as well if required.

    - A large number of timer setup conversions from Kees which got
    collected here because either maintainers requested so or they
    simply got ignored. As Kees pointed out already there are a few
    trivial merge conflicts and some redundant commits which was
    unavoidable due to the size of this conversion effort.

    - Avoid a redundant iteration in the timer wheel softirq processing.

    - Provide a mechanism to treat RTC implementations depending on their
    hardware properties, i.e. don't inflict the write at the 0.5
    seconds boundary which originates from the PC CMOS RTC to all RTCs.
    No functional change as drivers need to be updated separately.

    - The usual small updates to core code clocksource drivers. Nothing
    really exciting"

  • 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

  • c94e4ad2d   ARM: document and update UNCACHEABLE_ADDR definitions ... Browse Code »

    Document the UNCACHEABLE_ADDR definitions for footbridge and SA1100
    so that we know where they're located and/or what they're accessing.
    Change RiscPC to calculate the UNCACHEABLE_ADDR value from FLUSH_BASE
    as that's where we locate that.

    UNCACHEABLE_ADDR is used to perform an uncached access (ARMv4
    terminology) necessary to force a CPU clock-switch to the memory-
    speed clock, as required for entering WFI.

  • 9e0087e64   ARM: 8530/1: remove VIRT_TO_BUS ... Browse Code »

    All drivers that are relevant for rpc or footbridge have stopped
    using virt_to_bus a while ago, so we can remove it and avoid some
    harmless randconfig warnings for drivers that we do not care about:

    drivers/atm/zatm.c: In function 'poll_rx':
    drivers/atm/zatm.c:401:18: warning: 'bus_to_virt' is deprecated [-Wdeprecated-declarations]
    skb = ((struct rx_buffer_head *) bus_to_virt(here[2]))->skb;

    FWIW, the remaining drivers using this are:

    ATM: firestream, zatm, ambassador, horizon
    ISDN: hisax/netjet
    V4L: STA2X11, zoran
    Net: Appletalk LTPC, Tulip DE4x5, Toshiba IrDA
    WAN: comtrol sv11, cosa, lanmedia, sealevel
    SCSI: DPT_I2O, buslogic
    VME: CA91C142

    My best guess is that all of the above are so hopelessly obsolete that
    we are best off removing all of them form the kernel, but that can be
    done another time.

  • 0045c0dd2   ARM: debug-ll: rework footbridge handling ... Browse Code »

    Footbridge has two debug ports that are handled a bit differently:

    The 8250 port uses the normal debug/8250.S implementation that is shared
    with a lot of other platforms, but it relies on the DEBUG_UART_8250
    option to be turned on automatically instead of being selected by
    DEBUG_FOOTBRIDGE_COM1 as we do for most other platforms. I'm changing
    this to use a 'select' and change the dependency to the debug symbol
    rather than the platform symbol for consistency.

    The DC21285 UART has a separate top-level option, and relies on
    the traditional include/mach/debug-macro.S method. With the s3c64xx
    multiplatform series queued up for 4.5, it is now the last one that does
    this, so by moving this file to include/debug/dc21285.S, we can get
    all platforms to do things the same way.

  • bd0b9ac40   genirq: Remove irq argument from irq flow handlers ... Browse Code »

    Most interrupt flow handlers do not use the irq argument. Those few
    which use it can retrieve the irq number from the irq descriptor.

    Remove the argument.

    Search and replace was done with coccinelle and some extra helper
    scripts around it. Thanks to Julia for her help!

  • e8d36d5db   ARM: kill off set_irq_flags usage ... Browse Code »

    set_irq_flags is ARM specific with custom flags which have genirq
    equivalents. Convert drivers to use the genirq interfaces directly, so we
    can kill off set_irq_flags. The translation of flags is as follows:

    IRQF_VALID -> !IRQ_NOREQUEST
    IRQF_PROBE -> !IRQ_NOPROBE
    IRQF_NOAUTOEN -> IRQ_NOAUTOEN

    For IRQs managed by an irqdomain, the irqdomain core code handles clearing
    and setting IRQ_NOREQUEST already, so there is no need to do this in
    .map() functions and we can simply remove the set_irq_flags calls. Some
    users also modify IRQ_NOPROBE and this has been maintained although it
    is not clear that is really needed. There appears to be a great deal of
    blind copy and paste of this code.

  • c6f54a9b3   ARM: 8113/1: remove remaining definitions of PLAT_PHYS_OFFSET from <mach/memory.h> ... Browse Code »

    The platforms selecting NEED_MACH_MEMORY_H defined the start address of
    their physical memory in the respective . With
    ARM_PATCH_PHYS_VIRT=y (which is quite common today) this is useless
    though because the definition isn't used but determined dynamically.

    So remove the definitions from all and provide the
    Kconfig symbol PHYS_OFFSET with the respective defaults in case
    ARM_PATCH_PHYS_VIRT isn't enabled.

    This allows to drop the dependency of PHYS_OFFSET on !NEED_MACH_MEMORY_H
    which prevents compiling an integrator nommu-kernel.
    (CONFIG_PAGE_OFFSET which has "default PHYS_OFFSET if !MMU" expanded to
    "0x" because CONFIG_PHYS_OFFSET doesn't exist as INTEGRATOR selects
    NEED_MACH_MEMORY_H.)

    The global screen_info structure is used to communicate

    dummy consoles are in use.

    This changes the footbridge code so we don't try to access

    This cleanup series gets rid of for platforms not using
    ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
    387798b (ARM: initial multiplatform support).)

    To make this work some code out of arch/arm needed to be adapted. The
    respective changes got acks by their maintainers to be taken via armsoc
    (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).

    Compared to the previous pull request there was another patch added that
    fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
    squash this fix into the original commit to save him from the need to
    reverify the series.
