    Use the wrapper function for retrieving the platform data instead of
    accessing dev->platform_data directly. This is a cosmetic change to make
    the code simpler and enhance the readability.

  • 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.

  • 16380c153   RTC: Convert rtc drivers to use the alarm_irq_enable method ... Browse Code »

    Some rtc drivers use the ioctl method instead of the alarm_irq_enable
    method for enabling alarm interupts. With the new virtualized RTC
    rework, its important for drivers to use the alarm_irq_enable instead.

    This patch converts the drivers that use the AIE ioctl method to
    use the alarm_irq_enable method. Other ioctl cmds are left untouched.

    I have not been able to test or even compile most of these drivers.
    Any help to make sure this change is correct would be appreciated!

  • 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.

    Herton Ronaldo Krzesinski recently raised up, and fixed, an issue with the

    This patch ensures that driver data registration happens before

  • 2fac6674d   rtc: bunch of drivers: fix 'no irq' case handing ... Browse Code »

    This patch fixes a bunch of irq checking misuses. Most drivers were
    getting irq via platform_get_irq(), which returns -ENXIO or r->start.

    rtc-cmos.c is special. It is using PNP and platform bindings. Hopefully
    nobody is using PNP IRQ 0 for RTC. So the changes should be safe.

    rtc-sh.c is using platform_get_irq, but was storing a result into an
    unsigned type, then was checking for < 0. This is fixed now.

  • 01e8ef11b   x86: sysfs: kill owner field from attribute ... Browse Code »

    Tejun's commit 7b595756ec1f49e0049a9e01a1298d53a7faaa15 made sysfs
    attribute->owner unnecessary. But the field was left in the structure to
    ease the merge. It's been over a year since that change and it is now
    time to start killing attribute->owner along with its users - one arch at
    a time!

    This patch is attempt #1 to get rid of attribute->owner only for
    CONFIG_X86_64 or CONFIG_X86_32 . We will deal with other arches later on
    as and when possible - avr32 will be the next since that is something I
    can test. Compile (make allyesconfig / make allmodconfig / custom config)
    and boot tested.

    akpm: the idea is that we put the declaration of sttribute.owner inside
    `#ifndef CONFIG_X86'. But that proved to be too ambitious for now because
    new usages kept on turning up in subsystem trees.

  • a4b1d50e6   RTCs: handle NVRAM better ... Browse Code »

    Several of the RTC drivers are exporting binary "nvram" files in sysfs. Such
    NVRAM (or on many systems, EEPROM) data is often initialized during system
    manufacture to hold data about identity (serial numbers, Ethernet addresses,
    etc), configuration, calibration, and so forth.

    This patch improves integrity and security of those files:

    - Correctly initializes the size in one of the two cases where
    that was not yet being done.

    - Improves system security/integrity by making this state not
    be world-writable by default.

    Letting arbitrary userspace code mangle such state by default is at least Not
    A Good Thing; and it could sometimes be worse, depending on the particular
    data that might be corrupted. (I disregard the paranoiac "don't let anyone
    read it either" approach. Anyone storing passwords in such memory doesn't
    really care about security.)
