  • b57287ba4   video: platinumfb: Add __devexit_p at necessary place ... Browse Code »

    According to the comments in include/linux/init.h:

    "Pointers to __devexit functions must use __devexit_p(function_name), the
    wrapper will insert either the function_name or NULL, depending on the config
    options."

    We have __devexit annotation for platinumfb_remove(), thus add __devexit_p at
    necessary place.

    of_device is just an alias for platform_device, so remove it entirely. Also
    replace to_of_device() with to_platform_device() and update comment blocks.

    This patch was initially generated from the following semantic patch, and then

  • 4018294b5   of: Remove duplicate fields from of_platform_driver ... Browse Code »

    .name, .match_table and .owner are duplicated in both of_platform_driver
    and device_driver. This patch is a removes the extra copies from struct
    of_platform_driver and converts all users to the device_driver members.

    This patch is a pretty mechanical change. The usage model doesn't change
    and if any drivers have been missed, or if anything has been fixed up
    incorrectly, then it will fail with a compile time error, and the fixup
    will be trivial. This patch looks big and scary because it touches so
    many files, but it should be pretty safe.

  • 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.

  • 537a1bf05   fbdev: add mutex for fb_mmap locking ... Browse Code »
    43

    Add a mutex to avoid a circular locking problem between the mm layer
    semaphore and fbdev ioctl mutex through the fb_mmap() call.

    Also, add mutex to all places where smem_start and smem_len fields change
    so the mutex inside the fb_mmap() is actually used. Changing of these
    fields before calling the framebuffer_register() are not mutexed.

    This is 2.6.31 material. It removes one lockdep (fb_mmap() and
    register_framebuffer()) but there is still another one (fb_release() and
    register_framebuffer()). It also cleans up handling of the smem_start and
    smem_len fields used by mutexed section of the fb_mmap().

  • 6473d160b   PCI: Cleanup the includes of <linux/pci.h> ... Browse Code »

    I noticed that many source files include while they do
    not appear to need it. Here is an attempt to clean it all up.

    In order to find all possibly affected files, I searched for all
    files including but without any other occurence of "pci"
    or "PCI". I removed the include statement from all of these, then I
    compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
    false positives manually.

    My tests covered 66% of the affected files, so there could be false
    positives remaining. Untested files are:

    arch/alpha/kernel/err_common.c
    arch/alpha/kernel/err_ev6.c
    arch/alpha/kernel/err_ev7.c
    arch/ia64/sn/kernel/huberror.c

    I would welcome test reports for these files. I am fine with removing
    the untested files from the patch if the general opinion is that these
    changes aren't safe. The tested part would still be nice to have.

    Note that this patch depends on another header fixup patch I submitted
    to LKML yesterday:

  • 7eebde700   [POWERPC] Souped-up of_platform_device support ... Browse Code »

    This patch first splits of_device.c and of_platform.c, the later containing
    the bits relative to of_platform_device's. On the "breaks" side of things,
    drivers uisng of_platform_device(s) need to include asm/of_platform.h now
    and of_(un)register_driver is now of_(un)register_platform_driver.

    In addition to a few utility functions to locate of_platform_device(s),
    the main new addition is of_platform_bus_probe() which allows the platform
    code to trigger an automatic creation of of_platform_devices for a whole
    tree of devices.

    The function acts based on the type of the various "parent" devices encountered
    from a provided root, using either a default known list of bus types that can be
    "probed" or a passed-in list. It will only register devices on busses matching
    that list, which mean that typically, it will not register PCI devices, as
    expected (since they will be picked up by the PCI layer).

    This will be used by Cell platforms using 4xx-type IOs in the Axon bridge
    and can be used by any embedded-type device as well.

  • c465e05a0   [PATCH] fbcon/fbdev: Move softcursor out of fbdev to fbcon ... Browse Code »

    According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
    drivers that do not support hardware cursors is redundant. The soft_cursor
    function is usable by all drivers because it is just a wrapper around
    fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is
    moved to the console directory.

    Thus, drivers that do not support hardware cursors can leave the fb_cursor
    field blank. For drivers that do, they can fill up this field with their own
    version.

    The end result is a smaller code size. And if the framebuffer console is not
    loaded, module/kernel size is also reduced because the soft_cursor module will
    also not be loaded.

    Initial git repository build. I'm not bothering with the full history,

    3.2GB when imported into git - space that would just make the early
