  • 0c4eae665   rtc: convert drivers/rtc/* to use module_platform_driver() ... Browse Code »

    This patch converts the drivers in drivers/rtc/* to use the
    module_platform_driver() macro which makes the code smaller and a bit
    simpler.

  • 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.

  • b74d2caa6   rtc: fix driver data issues in several rtc drivers ... Browse Code »

    Herton Ronaldo Krzesinski recently raised up, and fixed, an issue with the
    rtc_cmos driver, which was referring to an inconsistent driver data.

    This patch ensures that driver data registration happens before
    rtc_device_register().

  • bcb3a1676   rtc: v3020: fix v3020_mmio_read_bit() ... Browse Code »

    v3020_mmio_read_bit() always returns 0 when left_shift > 7.

    v3020_mmio_read_bit()'s return type is (unsigned char). The code returns
    a value masked by (1 << left_shift) that is casted to the return type. If
    left_shift is larger than 7, the cast will always result in a 0 return
    value. The problem was discovered with left_shift = 16, and the included
    patch corrects the problem.

    The bug was introduced in the last (Apr 3 2009) commit of the file, kernel
    versions 2.6.30 and later.

  • 362600fe6   [PATCH] Add v3020 RTC support ... Browse Code »

    This patch adds support for the v3020 RTC from EM Microelectronic.

    The v3020 RTC is designed to be connected on a bus using only one data bit.
    Since any data bit may be used, it is necessary to specify this to the
    driver by passing a struct v3020_platform_data pointer (see
    include/linux/rtc-v3020.h) to the driver.

    Part of the following code comes from the kernel patchs produced by
    Compulab for their products. The original file (available here:
    http://raph.people.8d.com/misc/emv3020.c) was released under the terms of
    the GPL license.
