  • ad7ad57c6   [SPARC64]: Fix conflicts in SBUS/PCI/EBUS/ISA DMA handling. ... Browse Code »

    Fully unify all of the DMA ops so that subordinate bus types to
    the DMA operation providers (such as ebus, isa, of_device) can
    work transparently.

    Basically, we just make sure that for every system device we
    create, the dev->archdata 'iommu' and 'stc' fields are filled
    in.

    Then we have two platform variants of the DMA ops, one for SUN4U which
    actually programs the real hardware, and one for SUN4V which makes
    hypervisor calls.

    This also fixes the crashes in parport_pc on sparc64, reported by
    Meelis Roos.

    Some of the code has been gradually transitioned to using the proper
    struct request_queue, but there's lots left. So do a full sweet of
    the kernel and get rid of this typedef and replace its uses with
    the proper type.

  • 10a0a8d4e   Add common orderly_poweroff() ... Browse Code »

    Various pieces of code around the kernel want to be able to trigger an
    orderly poweroff. This pulls them together into a single
    implementation.

    By default the poweroff command is /sbin/poweroff, but it can be set
    via sysctl: kernel/poweroff_cmd. This is split at whitespace, so it
    can include command-line arguments.

    This patch replaces four other instances of invoking either "poweroff"
    or "shutdown -h now": two sbus drivers, and acpi thermal
    management.

    sparc64 has its own "powerd"; still need to determine whether it should
    be replaced by orderly_poweroff().

  • 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
    arch/ia64/sn/kernel/xpnet.c
    arch/m68knommu/kernel/dma.c
    arch/mips/lib/iomap.c
    arch/powerpc/platforms/pseries/ras.c
    arch/ppc/8260_io/enet.c
    arch/ppc/8260_io/fcc_enet.c
    arch/ppc/8xx_io/enet.c
    arch/ppc/syslib/ppc4xx_sgdma.c
    arch/sh64/mach-cayman/iomap.c
    arch/xtensa/kernel/xtensa_ksyms.c
    arch/xtensa/platform-iss/setup.c
    drivers/i2c/busses/i2c-at91.c
    drivers/i2c/busses/i2c-mpc.c
    drivers/media/video/saa711x.c
    drivers/misc/hdpuftrs/hdpu_cpustate.c
    drivers/misc/hdpuftrs/hdpu_nexus.c
    drivers/net/au1000_eth.c
    drivers/net/fec_8xx/fec_main.c
    drivers/net/fec_8xx/fec_mii.c
    drivers/net/fs_enet/fs_enet-main.c
    drivers/net/fs_enet/mac-fcc.c
    drivers/net/fs_enet/mac-fec.c
    drivers/net/fs_enet/mac-scc.c
    drivers/net/fs_enet/mii-bitbang.c
    drivers/net/fs_enet/mii-fec.c
    drivers/net/ibm_emac/ibm_emac_core.c
    drivers/net/lasi_82596.c
    drivers/parisc/hppb.c
    drivers/sbus/sbus.c
    drivers/video/g364fb.c
    drivers/video/platinumfb.c
    drivers/video/stifb.c
    drivers/video/valkyriefb.c
    include/asm-arm/arch-ixp4xx/dma.h
    sound/oss/au1550_ac97.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:

  • 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).

  • 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.

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

    Run this:

    #!/bin/sh
    for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
    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.
