  • a28885bc7   rtc: make of_device_ids const ... Browse Code »

    of_device_ids (i.e. compatible strings and the respective data) are not
    supposed to change at runtime. All functions working with of_device_ids
    provided by work with const of_device_ids. This allows to
    mark all struct of_device_id below drivers/rtc const, too.

  • 5a167f454   Drivers: rtc: remove __dev* attributes. ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
    markings need to be removed.

    This change removes the use of __devinit, __devexit_p, __devinitdata,
    __devinitconst, and __devexit from these drivers.

    Based on patches originally written by Bill Pemberton, but redone by me
    in order to handle some of the coding style issues better, by hand.

  • e48b5e825   rtc: Fix possible null pointer dereference in rtc-mpc5121.c ... Browse Code »

    Mark Loard pointed out:
    "For example, this beauty from rtc-mpc5121.c in the same update:
    ...
    rtc->rtc = rtc_device_register("mpc5200-rtc", &op->dev,
    &mpc5200_rtc_ops, THIS_MODULE);
    ...

    rtc->rtc->uie_unsupported = 1; // <<<< Ooops NULL pointer >>>>

    if (IS_ERR(rtc->rtc)) { // <<<< this needs to be earlier >>>>
    err = PTR_ERR(rtc->rtc);
    goto out_free_irq;
    }
    ..."

    This patch moves setting the uie_unsupported flag to after we validate
    the rtc->rtc pointer to resolve this.

    Since commit e58aa3d2d0cc ("genirq: run irq handlers with interrupts
    disabled") we run all interrupt handlers with interrupts disabled and we
    even check and yell when an interrupt handler returns with interrupts
    enabled - see commit b738a50a2026 ("genirq: warn when handler enables
    interrupts").

    So now this flag is a NOOP and can be removed.

  • 4a649903f   rtc: Provide flag for rtc devices that don't support UIE ... Browse Code »

    Richard Weinberger noticed that on some RTC hardware that
    doesn't support UIE mode, due to coarse granular alarms
    (like 1minute resolution), the current virtualized RTC
    support doesn't properly error out when UIE is enabled.

    Instead the current code queues an alarm for the next second,
    but it won't fire until up to a miniute later.

    This patch provides a generic way to flag this sort of hardware
    and fixes the issue on the mpc5121 where Richard noticed the
    problem.

    Now that the generic code handles UIE mode irqs via periodic
    alarm interrupts, no one calls the
    rtc_class_ops->update_irq_enable() method anymore.

    This patch removes the driver hooks and implementations of
    update_irq_enable if no one else is calling it.

  • 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.
