  • b859f1592   Drivers: platform: x86: 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.

  • a6c2390cd   dell-laptop: Remove rfkill code ... Browse Code »

    The interface just doesn't work on some machines, and Dell haven't been
    able to tell us either which machines those are or what we should be
    doing instead. This would be fine, except it results in userspace ending
    up confused and general sadness. So let's just rip it out for now.

  • 2d8b90be4   dell-laptop: support Synaptics/Alps touchpad led ... Browse Code »

    This patch supports Dell laptop with Synaptics and Alps touchpad chip
    that with LED to indicate the functionality of touchpad is disabled or
    enabled.

    The command for touchpad LED is 0x97, and the data 1 means turn on the
    touchpad LED, 2 means turn it off.

    BTW, I add dell_quirks to white list those machines that supports this
    behavior, so that the code won't affect those who don't have a touchpad LED
    machine.

    We can easily to turn it on/off by
    echo 1 > /sys/class/leds/dell-laptop::touchpad/brightness
    echo 0 > /sys/class/leds/dell-laptop::touchpad/brightness

    There may be multiple ways of controlling the backlight on a given
    machine. Allow drivers to expose the type of interface they are
    providing, making it possible for userspace to make appropriate policy

  • a3d77411e   dell-laptop: Toggle the unsupported hardware killswitch ... Browse Code »

    It is found on Dell Inspiron 1018 that the firmware reports that the hardware
    killswitch is not supported. This makes the rfkill key not functional.

    This patch forces the driver to toggle the firmware rfkill status in the case
    that the hardware killswitch is indicated as unsupported by the firmware.

  • acc2472ed   backlight: constify backlight_ops ... Browse Code »

    backlight_device_register has been expecting a const "ops" argument, and using
    it as such, since 9905a43b2d563e6f89e4c63c4278ada03f2ebb14. Let's make the
    remaining backlight_ops instances const.

    Inspired by hunks of the grsecurity patch, updated for newer kernels.

    Export the status of RF killswitch through debugfs.

    The killswitch status is obtained by the SMI to BIOS. Exporting this status
    through debugfs can help identify the issue with the misbehaving firmware.

  • 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.
