    zorro-driver.c: fix four checkpatch warnings of:
    WARNING: EXPORT_SYMBOL(foo); should immediately follow its function/variable

    I had a cat. The cat was mine.
    His name was Zorro. Amiga is fine.

  • a7f4d00a8   zorro: Defer device_register() until all devices have been identified ... Browse Code »
    1

    As the Amiga Zorro II address space is limited to 8.5 MiB and Zorro
    devices can contain only one BAR, several Amiga Zorro II expansion
    boards (mainly graphics cards) contain multiple Zorro devices: a small
    one for the control registers and one (or more) for the graphics memory.

    The conversion of cirrusfb to the new driver framework introduced a
    regression: the driver contains a zorro_driver for the first Zorro
    device, and uses the (old) zorro_find_device() call to find the second
    Zorro device.

    However, as the Zorro core calls device_register() as soon as a Zorro
    device is identified, it may not have identified the second Zorro device
    belonging to the same physical Zorro expansion card. Hence cirrusfb
    could no longer find the second part of the Picasso II graphics card,
    causing a NULL pointer dereference.

    Defer the registration of Zorro devices with the driver framework until
    all Zorro devices have been identified to fix this.

    Note that the alternative solution (modifying cirrusfb to register a
    zorro_driver for all Zorro devices belonging to a graphics card, instead
    of only for the first one, and adding a synchronization mechanism to
    defer initialization until all have been found), is not an option, as on
    some cards one device may be optional (e.g. the second bank of 2 MiB of
    graphics memory on the Picasso IV in Zorro II mode).

  • e108526e7   move memory_read_from_buffer() from fs.h to string.h ... Browse Code »

    James Bottomley warns that inclusion of linux/fs.h in a low level
    driver was always a danger signal. This patch moves
    memory_read_from_buffer() from fs.h to string.h and fixes includes in
    existing memory_read_from_buffer() users.

    * Convert files to UTF-8.

    * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

    * Correct town names (Goettingen -> Göttingen)

    * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

  • 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.

  • 00977a59b   [PATCH] mark struct file_operations const 6 ... Browse Code »

    Many struct file_operations in the kernel can be "const". Marking them const
    moves these to the .rodata section, which avoids false sharing with potential
    dirty data. In addition it'll catch accidental writes at compile time to
    these shared resources.

  • 33d8675ea   [PATCH] amiga: fix driver_register() return handling, remove zorro_module_init() ... Browse Code »

    Remove the assumption that driver_register() returns the number of devices
    bound to the driver. In fact, it returns zero for success or a negative
    error value.

    zorro_module_init() used the device count to automatically unregister and
    unload drivers that found no devices. That might have worked at one time,
    but has been broken for some time because zorro_register_driver() returned
    either a negative error or a positive count (never zero). So it could only
    unregister on failure, when it's not needed anyway.

    This functionality could be resurrected in individual drivers by counting
    devices in their .probe() methods.

  • 4e57b6817   [PATCH] fix missing includes ... Browse Code »

    I recently picked up my older work to remove unnecessary #includes of
    sched.h, starting from a patch by Dave Jones to not include sched.h
    from module.h. This reduces the number of indirect includes of sched.h
    by ~300. Another ~400 pointless direct includes can be removed after
    this disentangling (patch to follow later).
    However, quite a few indirect includes need to be fixed up for this.

    In order to feed the patches through -mm with as little disturbance as
    possible, I've split out the fixes I accumulated up to now (complete for
    i386 and x86_64, more archs to follow later) and post them before the real
    patch. This way this large part of the patch is kept simple with only
    adding #includes, and all hunks are independent of each other. So if any
    hunk rejects or gets in the way of other patches, just drop it. My scripts
    will pick it up again in the next round.

    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!
