  • 1ac71e5a3   pcmcia: convert pcmcia_request_configuration to pcmcia_enable_device ... Browse Code »

    pcmcia_enable_device() now replaces pcmcia_request_configuration().
    Instead of config_req_t, all necessary flags are either passed as
    a parameter to pcmcia_enable_device(), or (in rare circumstances)
    set in struct pcmcia_device -> flags.

    With the last remaining user of include/pcmcia/cs.h gone, remove
    all references.

    Remove cs_types.h which is no longer needed: Most definitions aren't
    used at all, a few can be made away with, and two remaining definitions
    (typedefs, unfortunatley) may be moved to more specific places.

  • 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.

  • 9fea84f46   pcmcia: CodingStyle fixes ... Browse Code »

    Fix several CodingStyle issues in drivers/pcmcia/ . checkpatch.pl no longer
    reports errors in the PCMCIA core. The remaining warnings mostly relate to
    wrong indent -- PCMCIA historically used 4 spaces --, to lines over 80
    characters and to hundreds of typedefs. The cleanup of those will follow
    in the future.

  • 84897fc05   pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanup ... Browse Code »

    pccard_read_tuple(), which is only used by the PCMCIA core, should
    handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which
    may be 0) is requested, set tuple.Attributes = 0 as was done in all
    PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the
    "common" tuple. As to the callers of pccard_read_tuple():

    - All calls to pcmcia_validate_cis() had set the "function" parameter to
    BIND_FN_ALL. Therefore, remove the "function" parameter and make the
    parameter to pccard_read_tuple explicit.

    - Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was
    already the case for calls to CISTPL_LONGLINK_MFC.

  • 4356d73d0   pcmcia: remove pccard_sysfs_interface warnings ... Browse Code »

    Make the PCMCIA core stop using class_interface to hide socket attribute
    registration. This removes the associated section mismatch warnings, and
    helps get to the point where that mechanism can finally be removed.

    Simplify that attribute registration by using an attribute_group.
    This is a net shrink in object size.

  • 91a690295   sysfs: add parameter "struct bin_attribute *" in .read/.write methods for sysfs binary attributes ... Browse Code »

    Well, first of all, I don't want to change so many files either.

    What I do:
    Adding a new parameter "struct bin_attribute *" in the
    .read/.write methods for the sysfs binary attributes.

    In fact, only the four lines change in fs/sysfs/bin.c and
    include/linux/sysfs.h do the real work.
    But I have to update all the files that use binary attributes
    to make them compatible with the new .read and .write methods.
    I'm not sure if I missed any. :(

    Why I do this:
    For a sysfs attribute, we can get a pointer pointing to the
    struct attribute in the .show/.store method,
    while we can't do this for the binary attributes.
    I don't know why this is different, but this does make it not
    so handy to use the binary attributes as the regular ones.
    So I think this patch is reasonable. :)

    Who benefits from it:
    The patch that exposes ACPI tables in sysfs
    requires such an improvement.
    All the table binary attributes share the same .read method.
    Parameter "struct bin_attribute *" is used to get
    the table signature and instance number which are used to
    distinguish different ACPI table binary attributes.

    Without this parameter, we need to offer different .read methods
    for different ACPI table binary attributes.
    This is impossible as there are various ACPI tables on different
    platforms, and we don't know what they are until they are loaded.

  • 7b595756e   sysfs: kill unnecessary attribute->owner ... Browse Code »

    sysfs is now completely out of driver/module lifetime game. After
    deletion, a sysfs node doesn't access anything outside sysfs proper,
    so there's no reason to hold onto the attribute owners. Note that
    often the wrong modules were accounted for as owners leading to
    accessing removed modules.

    This patch kills now unnecessary attribute->owner. Note that with
    this change, userland holding a sysfs node does not prevent the
    backing module from being unloaded.

    For more info regarding lifetime rule cleanup, please read the
    following message.

  • 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

    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:

  • d834c1651   pccard_store_cis: fix wrong error handling ... Browse Code »

    The test for the error from pcmcia_replace_cis() was incorrect, and
    would always trigger (because if an error didn't happen, the "ret" value
    would not be zero, it would be the passed-in count).

    Reported and debugged by Fabrice Bellet

    Rather than just fix the single broken test, make the code in question
    use an understandable code-sequence instead, fixing the whole function
    to be more readable.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
