  • module_param(bool) used to counter-intuitively take an int. In
    fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
    trick.

    It's time to remove the int/unsigned int option. For this version
    it'll simply give a warning, but it'll break next kernel version.

  • Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
    We run all interrupt handlers with interrupts disabled
    and we even check and yell when an interrupt handler
    returns with interrupts enabled (see commit [b738a50a:
    genirq: Warn when handler enables interrupts]).

    So now this flag is a NOOP and can be removed.

  • 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
    edited by hand to pick up the bits that coccinelle didn't catch.

  • Both of_bus_type and of_platform_bus_type are just #define aliases
    for the platform bus. This patch removes all references to them and
    switches to the of_register_platform_driver()/of_unregister_platform_driver()
    API for registering.

    Subsequent patches will convert each user of of_register_platform_driver()
    into plain platform_drivers without the of_platform_driver shim. At which
    point the of_register_platform_driver()/of_unregister_platform_driver()
    functions can be removed.

  • This patch moves SPARC architecture specific data members out of
    struct of_device and into the pdev_archdata structure. The reason
    for this change is to unify the struct of_device definition amongst
    all the architectures. It also remvoes the .sysdata, .slot, .portid
    and .clock_freq properties because they aren't actually used by
    anything.

    A subsequent patch will replace struct of_device entirely with struct
    platform_device and the of_platform support code will share common
    routines with the platform bus (but the bus instances themselves can
    remain separate).

    This patch also adds 'struct resources *resource' and num_resources
    to match the fields defined in struct platform_device. After this
    change, 'struct platform_device' can be used as a drop-in replacement
    for 'struct of_platform'.

    This change is in preparation for merging the of_platform_bus_type
    with the platform_bus_type.

  • .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.

  • This header file exists only for some hacks to adapt alsa-driver
    tree. It's useless for building in the kernel. Let's move a few
    lines in it to sound/core.h and remove it.
    With this patch, sound/driver.h isn't removed but has just a single
    compile warning to include it. This should be really killed in
    future.

  • Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
    of passing regs around manually through all ~1800 interrupt handlers in the
    Linux kernel.

    The regs pointer is used in few places, but it potentially costs both stack
    space and code to pass it around. On the FRV arch, removing the regs parameter
    from all the genirq function results in a 20% speed up of the IRQ exit path
    (ie: from leaving timer_interrupt() to leaving do_IRQ()).

    Where appropriate, an arch may override the generic storage facility and do
    something different with the variable. On FRV, for instance, the address is
    maintained in GR28 at all times inside the kernel as part of general exception
    handling.

    Having looked over the code, it appears that the parameter may be handed down
    through up to twenty or so layers of functions. Consider a USB character
    device attached to a USB hub, attached to a USB controller that posts its
    interrupts through a cascaded auxiliary interrupt controller. A character
    device driver may want to pass regs to the sysrq handler through the input
    layer which adds another few layers of parameter passing.

    I've build this code with allyesconfig for x86_64 and i386. I've runtested the
    main part of the code on FRV and i386, though I can't test most of the drivers.
    I've also done partial conversion for powerpc and MIPS - these at least compile
    with minimal configurations.

    This will affect all archs. Mostly the changes should be relatively easy.
    Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

    struct pt_regs *old_regs = set_irq_regs(regs);

    And put the old one back at the end:

    set_irq_regs(old_regs);

    Don't pass regs through to generic_handle_irq() or __do_IRQ().

    In timer_interrupt(), this sort of change will be necessary:

    - update_process_times(user_mode(regs));
    - profile_tick(CPU_PROFILING, regs);
    + update_process_times(user_mode(get_irq_regs()));
    + profile_tick(CPU_PROFILING);

    I'd like to move update_process_times()'s use of get_irq_regs() into itself,
    except that i386, alone of the archs, uses something other than user_mode().

    Some notes on the interrupt handling in the drivers:

    (*) input_dev() is now gone entirely. The regs pointer is no longer stored in
    the input_dev struct.

    (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does
    something different depending on whether it's been supplied with a regs
    pointer or not.

    (*) Various IRQ handler function pointers have been moved to type
    irq_handler_t.

  • This ugly hack was long overdue to die.

    It was a way to print out Sparc interrupts in a more freindly format,
    since IRQ numbers were arbitrary opaque 32-bit integers which vectored
    into PIL levels. These 32-bit integers were not necessarily in the
    0-->NR_IRQS range, but the PILs they vectored to were.

    The idea now is that we will increase NR_IRQS a little bit and use a
    virtualreal IRQ number mapping scheme similar to PowerPC.

    That makes this IRQ printing hack irrelevant, and furthermore only a
    handful of drivers actually used __irq_itoa() making it even less
    useful.

  • 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!
