  • 937949d9e   [PATCH] add process_session() helper routine ... Browse Code »

    Replace occurences of task->signal->session by a new process_session() helper
    routine.

    It will be useful for pid namespaces to abstract the session pid number.

  • 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.

    Pass struct dev pointer to dma_cache_sync()

    dma_cache_sync() is ill-designed in that it does not have a struct device
    pointer argument which makes proper support for systems that consist of a
    mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
    to take a struct device pointer as first argument and fix all its callers
    to pass it.

    Define elf_addr_t in linux/elf.h. The size of the type is determined using
    ELF_CLASS. This allows us to remove the defines that today are spread all
    over .c and .h files.

  • a866374ae   [PATCH] mm: pagefault_{disable,enable}() ... Browse Code »

    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)
