  • 7ed33ea6b   ALSA: Replace HTTP links with HTTPS ones ... Browse Code »

    Rationale:
    Reduces attack surface on kernel devs opening the links for MITM
    as HTTPS traffic is much harder to manipulate.

    Deterministic algorithm:
    For each file:
    If not .svg:
    For each line:
    If doesn't contain `\bxmlns\b`:
    For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
    If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
    If both the HTTP and HTTPS versions
    return 200 OK and serve the same content:
    Replace HTTP with HTTPS.

    ASoC: Updates for v5.1

    Lots and lots of new drivers so far, a highlight being the MediaTek
    BTCVSD which is a driver for a Bluetooth radio chip - the first such
    driver we've had upstream. Hopefully we will soon also see a baseband
    with an upstream driver!

    - Support for only powering up channels that are actively being used.
    - Quite a few improvements to simplify the generic card drivers,
    especially the merge of the SCU cards into the main generic drivers.
    - Lots of fixes for probing on Intel systems, trying to rationalize
    things to look more standard from a framework point of view.
    - New drivers for Asahi Kasei Microdevices AK4497, Cirrus Logic CS4341,
    Google ChromeOS embedded controllers, Ingenic JZ4725B, MediaTek
    BTCVSD, MT8183 and MT6358, NXP MICFIL, Rockchip RK3328, Spreadtrum
    DMA controllers, Qualcomm WCD9335, Xilinx S/PDIF and PCM formatters.

  • 16f46050e   dbri: Fix compiler warning ... Browse Code »

    dbri uses 'u32' for dma handle while invoking kernel DMA APIs,
    instead of using dma_addr_t. This hasn't caused any 'incompatible
    pointer type' warning on SPARC because until now dma_addr_t is of
    type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit
    DMA and therefore dma_addr_t became of type u64. This makes
    'incompatible pointer type' warnings inevitable.

    e.g.
    sound/sparc/dbri.c: In function ‘snd_dbri_create’:
    sound/sparc/dbri.c:2538: warning: passing argument 3 of ‘dma_zalloc_coherent’ from incompatible pointer type
    ./include/linux/dma-mapping.h:608: note: expected ‘dma_addr_t *’ but argument is of type ‘u32 *’

    For the record, dbri(sbus) driver never executes on sun4v. Therefore
    even though 64bit DMA is enabled on SPARC, dbri continues to use
    legacy iommu that guarantees DMA address is always in 32bit range.

    This patch resolves above compiler warning.

    module_param(bool) used to counter-intuitively take an int. In

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

  • 1636f8ac2   sparc/of: Move of_device fields into struct pdev_archdata ... Browse Code »

    This patch moves SPARC architecture specific data members out of
    struct of_device and into the pdev_archdata structure. The reason
    for this change is to unify the struct of_device definition amongst
    all the architectures. It also remvoes the .sysdata, .slot, .portid
    and .clock_freq properties because they aren't actually used by
    anything.

    A subsequent patch will replace struct of_device entirely with struct
    platform_device and the of_platform support code will share common
    routines with the platform bus (but the bus instances themselves can
    remain separate).

    This patch also adds 'struct resources *resource' and num_resources
    to match the fields defined in struct platform_device. After this
    change, 'struct platform_device' can be used as a drop-in replacement
    for 'struct of_platform'.

    This change is in preparation for merging the of_platform_bus_type
    with the platform_bus_type.

    .name, .match_table and .owner are duplicated in both of_platform_driver
    and device_driver. This patch is a removes the extra copies from struct
    of_platform_driver and converts all users to the device_driver members.

    This patch is a pretty mechanical change. The usage model doesn't change
    and if any drivers have been missed, or if anything has been fixed up
    incorrectly, then it will fail with a compile time error, and the fixup
    will be trivial. This patch looks big and scary because it touches so
    many files, but it should be pretty safe.

  • 5a0e3ad6a   include cleanup: Update gfp.h and slab.h includes to prepare for breaking implic… ... Browse Code »

    …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
