    Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu",
    so that the user can disable all the options in that menu at once
    instead of having to disable each option separately.

  • 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
    arch/ia64/sn/kernel/huberror.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:
    [PATCH] scatterlist.h needs types.h

  • cd354f1ae   [PATCH] remove many unneeded #includes of sched.h ... Browse Code »

    After Al Viro (finally) succeeded in removing the sched.h #include in module.h
    recently, it makes sense again to remove other superfluous sched.h includes.
    There are quite a lot of files which include it but don't actually need
    anything defined in there. Presumably these includes were once needed for
    macros that used to live in sched.h, but moved to other header files in the
    course of cleaning it up.

    To ease the pain, this time I did not fiddle with any header files and only
    removed #includes from .c-files, which tend to cause less trouble.

    Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
    arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
    allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
    configs in arch/arm/configs on arm. I also checked that no new warnings were
    introduced by the patch (actually, some warnings are removed that were emitted
    by unnecessarily included header files).

  • 5cbded585   [PATCH] getting rid of all casts of k[cmz]alloc() calls ... Browse Code »

    Run this:

    #!/bin/sh

    echo "De-casting $f..."
    perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
    done

    And then go through and reinstate those cases where code is casting pointers
    to non-pointers.

    And then drop a few hunks which conflicted with outstanding work.

    - Eliminate casts to/from void*

    - Eliminate checks for conditions that never occur. These typically
    fall into two classes:

    1) Checking for 'dev_id == NULL', then it is never called with
    NULL as an argument.

    2) Checking for invalid irq number, when the only caller (the
    system) guarantees the irq handler is called with the proper
    'irq' number argument.

  • 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.
