  • 6168a702a   [PATCH] Declare init_irq_proc before we use it. ... Browse Code »

    powerpc gets:

    init/main.c: In function `do_basic_setup':
    init/main.c:714: warning: implicit declaration of function `init_irq_proc'

    but we cannot include linux/irq.h in generic code.

    Fix it by moving the declaration into linux/interrupt.h instead.

    And make sure all code that defines init_irq_proc() is including
    linux/interrupt.h.

    And nuke an ifdef-in-C

  • 5ea817699   [PATCH] sort the devres mess out ... Browse Code »

    * 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.

    Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs
    when CONFIG_BLK_DEV_INITRAMFS is not selected. This saves another 4 kbytes
    on most platfoms (some reserve PAGE_SIZE for initramfs).

  • 66701b149   [PATCH] optional ZONE_DMA: introduce CONFIG_ZONE_DMA ... Browse Code »

    This patch simply defines CONFIG_ZONE_DMA for all arches. We later do special
    things with CONFIG_ZONE_DMA after the VM and an arch are prepared to work
    without ZONE_DMA.

    CONFIG_ZONE_DMA can be defined in two ways depending on how an architecture
    handles ISA DMA.

    First if CONFIG_GENERIC_ISA_DMA is set by the arch then we know that the arch
    needs ZONE_DMA because ISA DMA devices are supported. We can catch this in
    mm/Kconfig and do not need to modify arch code.

    Second, arches may use ZONE_DMA in an unknown way. We set CONFIG_ZONE_DMA for
    all arches that do not set CONFIG_GENERIC_ISA_DMA in order to insure backwards
    compatibility. The arches may later undefine ZONE_DMA if their arch code has
    been verified to not depend on ZONE_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.

  • fd593d127   [PATCH] relocatable kernel: Kallsyms generate relocatable symbols ... Browse Code »

    Print the addresses of non-absolute symbols relative to _text
    so that ld will generate relocations. Allowing a relocatable
    kernel to relocate them. We can't actually use the symbol names
    because kallsyms includes static symbols that are not exported
    from their object files.

    Add the _text symbol definitions to the architectures which don't
    define it otherwise linker will fail.

  • fe74290d5   [PATCH] provide kernel_execve on all architectures ... Browse Code »

    This adds the new kernel_execve function on all architectures that were using
    _syscall3() to implement execve.

    The implementation uses code from the _syscall3 macros provided in the
    unistd.h header file. I don't have cross-compilers for any of these
    architectures, so the patch is untested with the exception of i386.

    Most architectures can probably implement this in a nicer way in assembly or
    by combining it with the sys_execve implementation itself, but this should do
    it for now.
