  • 45ac936c3   irda: remove __dev* attributes ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As result the __dev*
    markings will be going away.

    Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
    and __devexit.

  • c2fd03a01   drivers: net: Remove casts to same type ... Browse Code »

    Adding casts of objects to the same type is unnecessary
    and confusing for a human reader.

    For example, this cast:

    int y;
    int *p = (int *)&y;

    I used the coccinelle script below to find and remove these
    unnecessary casts. I manually removed the conversions this
    script produces of casts with __force, __iomem and __user.

    @@
    type T;
    T *p;
    @@

    - (T *)p
    + p

  • cd671c16f   net/irda: convert au1k_ir to platform driver. ... Browse Code »

    Moderate driver cleanup:
    convert to platform driver, get rid of board-specific code.

    Driver loads and runs on a DB1100 board. But since I have no other
    IrDA hardware to exchange data with I can't say whether it really sends
    and receives.

    Now that core network takes care of trans_start updates, dont do it
    in drivers themselves, if possible. Drivers can avoid one cache miss
    (on dev->trans_start) in their start_xmit() handler.

    Exceptions are NETIF_F_LLTX drivers

  • 9bdcf336d   MIPS: Alchemy: devboard register abstraction ... Browse Code »

    All Alchemy development boards have external CPLDs with a few registers
    in them. They all share an identical register layout with only a few
    minor differences (except the PB1000) in bit functions and base
    addresses.

    This patch
    - adds a primitive facility to initialize and use these external
    registers,
    - replaces all occurrences of bcsr->xxx accesses with calls to the new
    functions (the pb1200 cascade irq handling code is special).
    - collects BCSR register information scattered throughout the board
    headers in a central place.

  • 7d12e780e   IRQ: Maintain regs pointer globally rather than passing to IRQ handlers ... Browse Code »

    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.

    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!
