  • dc3e0aa5c   misc: remove redundant 'default n' from Kconfig-s ... Browse Code »

    'default n' is the default value for any bool or tristate Kconfig
    setting so there is no need to write it explicitly.

    Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
    is not set' for visible symbols") the Kconfig behavior is the same
    regardless of 'default n' being present or not:

    ...
    One side effect of (and the main motivation for) this change is making
    the following two definitions behave exactly the same:

    config FOO
    bool

    config FOO
    bool
    default n

    With this change, neither of these will generate a
    '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
    That might make it clearer to people that a bare 'default n' is
    redundant.

  • 495027667   kmemcheck: remove annotations ... Browse Code »

    Patch series "kmemcheck: kill kmemcheck", v2.

    As discussed at LSF/MM, kill kmemcheck.

    KASan is a replacement that is able to work without the limitation of
    kmemcheck (single CPU, slow). KASan is already upstream.

    We are also not aware of any users of kmemcheck (or users who don't
    consider KASan as a suitable replacement).

    The only objection was that since KASAN wasn't supported by all GCC
    versions provided by distros at that time we should hold off for 2
    years, and try again.

    Now that 2 years have passed, and all distros provide gcc that supports
    KASAN, kill kmemcheck again for the very same reasons.

    This patch (of 4):

    Remove kmemcheck annotations, and calls to kmemcheck from the kernel.

    [alexander.levin@verizon.com: correctly remove kmemcheck call from dma_map_sg_attrs]

  • e1d206018   c2port: fix bogus Kconfig "default no" ... Browse Code »

    Strictly speaking "no" is a valid, but undefined, Kconfig symbol. But what
    obviously was meant here was "n".

    While we're touching this Kconfig file also drop the superfluous
    dependency on C2PORT for C2PORT_DURAMAR_2150. Its Kconfig entry is
    already wrapped in "if C2PORT" and "endif".

  • 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.

    C2port implements a two wire serial communication protocol (bit

    Currently this code supports only flash programming through sysfs
    interface but extensions shoud be easy to add.
