  • 1d51c69fb   [SPARC]: avoid CHILD_MAX and OPEN_MAX constants ... Browse Code »

    I don't figure anyone really cares about SunOS syscall emulation, and I
    certainly don't. But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX
    compile-time constant, and these are almost the only ones. OPEN_MAX is a
    bogus constant with no meaning about anything. The RLIMIT_NOFILE resource
    limit is what sysconf (_SC_OPEN_MAX) actually wants to return.

    The CHILD_MAX cases weren't actually using anything I want to get rid of,
    but I noticed that they are there and are wrong too. The CHILD_MAX value
    is not really unlimited as a -1 return from sysconf indicates. The
    RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.

  • 34cc560e6   [SPARC]: Re-export saved_command_line to modules. ... Browse Code »

    This reverts some bogosity from the dynamic command-line
    changes made on sparc32 and sparc64.

    Drivers such as drivers/sbus/char/openprom.c reference
    saved_command_line, and can be modular.

    The boot_command_line is __initdata, yet the dynamic command-line
    changes add modular exports of that symbol, obviously wrong.

  • 5dfe4c964   [PATCH] mark struct file_operations const 2 ... 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.

  • 0e25338bc   [PATCH] signal: use kill_pgrp not kill_pg in the sunos compatibility code ... Browse Code »

    I am slowly moving to a model where all process killing is struct pid based
    instead of pid_t based. The sunos compatibility code is one of the last users
    of the old pid_t based kill_pg in the kernel. By being complete I allow for
    the future removal of kill_pg from the kernel, which will ensure I don't miss
    something.

    * Split the implementation-agnostic stuff in separate files.
    * Make sure that targets using non-default request_irq() pull
    kernel/irq/devres.o
    * Introduce new symbols (HAS_IOPORT and HAS_IOMEM) defaulting to positive;
    allow architectures to turn them off (we needed these symbols anyway for
    dependencies of quite a few drivers).
    * protect the ioport-related parts of lib/devres.o with CONFIG_HAS_IOPORT.

  • 4564f9e5f   [PATCH] consolidate line discipline number definitions ... Browse Code »

    The line discipline numbers N_* are currently defined for each architecture
    individually, but (except for a seeming mistake) identically, in
    asm/termios.h. There is no obvious reason why these numbers should be
    architecture specific, nor any apparent relationship with the termios
    structure. The total number of these, NR_LDISCS, is defined in linux/tty.h
    anyway. So I propose the following patch which moves the definitions of
    the individual line disciplines to linux/tty.h too.

    Three of these numbers (N_MASC, N_PROFIBUS_FDL, and N_SMSBLOCK) are unused
    in the current kernel, but the patch still keeps the complete set in case
    there are plans to use them yet.

  • 5ac6da669   [PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMA ... Browse Code »

    As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA
    channel management. Other functionality may still expect GFP_DMA to
    provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is
    set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to
    mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set
    theses explicitly in each arches Kconfig.

    Reviews must occur for each arch in order to determine if ZONE_DMA can be
    switched off. It can only be switched off if we know that all devices
    supported by a platform are capable of performing DMA transfers to all of
    memory (Some arches already support this: uml, avr32, sh sh64, parisc and
    IA64/Altix).

    In order to switch ZONE_DMA off conditionally, one would have to establish
    a scheme by which one can assure that no drivers are enabled that are only
    capable of doing I/O to a part of memory, or one needs to provide an
    alternate means of performing an allocation from a specific range of memory
    (like provided by alloc_pages_range()) and insure that all drivers use that
    call. In that case the arches alloc_dma_coherent() may need to be modified
    to call alloc_pages_range() instead of relying on GFP_DMA.

  • f0d1b0b30   [PATCH] LOG2: Implement a general integer log2 facility in the kernel ... Browse Code »

    This facility provides three entry points:

    ilog2() Log base 2 of unsigned long
    ilog2_u32() Log base 2 of u32
    ilog2_u64() Log base 2 of u64

    These facilities can either be used inside functions on dynamic data:

    int do_something(long q)
    {
    ...;
    y = ilog2(x)
    ...;
    }

    Or can be used to statically initialise global variables with constant values:

    unsigned n = ilog2(27);

    When performing static initialisation, the compiler will report "error:
    initializer element is not constant" if asked to take a log of zero or of
    something not reducible to a constant. They treat negative numbers as
    unsigned.

    When not dealing with a constant, they fall back to using fls() which permits
    them to use arch-specific log calculation instructions - such as BSR on
    x86/x86_64 or SCAN on FRV - if available.

    Introduce pagefault_{disable,enable}() and use these where previously we did
    manual preempt increments/decrements to make the pagefault handler do the
    atomic thing.

    Currently they still rely on the increased preempt count, but do not rely on
    the disabled preemption, this might go away in the future.

    (NOTE: the extra barrier() in pagefault_disable might fix some holes on
    machines which have too many registers for their own good)

    When I added the entries for the robust futex syscall entries, I

    And wire up sys_migrate_pages since the powerpc folks implemented the
