  • fdomain is one of those drivers that is compiled twice, once for PCMCIA
    and once for non-PCMCIA. The resultant two-driver setup leaves a bit of
    dead code and data in the non-PCMCIA case, which gcc complains about.

    Shuffle ifdefs a bit to eliminate the conditionally-dead code, and
    the compiler warnings.

  • Doesn't make the hardware hot pluggable but does ensure the driver won't
    crash when another device is hot-unplugged at the wrong moment. Soon I
    propose to deprecate pci_find_device() and some of its friends.

  • 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.

  • Wrap a highly common idiom. Makes the code easier to read, helps pave
    the way for sdev->{id,channel} removal, and adds a token that can easily
    by grepped-for in the future.

    There are a couple sdev_id() and scmd_printk() updates thrown in as well.

  • `gcc -W' likes to complain if the static keyword is not at the beginning of
    the declaration. This patch fixes all remaining occurrences of "inline
    static" up with "static inline" in the entire kernel tree (140 occurrences in
    47 files).

    While making this change I came across a few lines with trailing whitespace
    that I also fixed up, I have also added or removed a blank line or two here
    and there, but there are no functional changes in the patch.

  • scsi_add_host is the proper place to set the device, but people copy
    the scsi_set_device usage from older drivers again and again.

    note that this leaves some legacy drivers like qlogicisp/qlogicfc
    without pci association in sysfs, but they're scheduled to go away soon
    anyway.

  • 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!
