  • 1b0fac458   dma-mapping: prevent dma dependent code from linking on !HAS_DMA archs ... Browse Code »

    Continuing the work started in 411f0f3edc141a582190d3605cadd1d993abb6df ...

    This enables code with a dma path, that compiles away, to build without
    requiring additional code factoring. It also prevents code that calls
    dma_alloc_coherent and dma_free_coherent from linking whereas previously
    the code would hit a BUG() at run time. Finally, it allows archs that set
    !HAS_DMA to delete their asm/dma-mapping.h file.

  • f7e4217b0   rename thread_info to stack ... Browse Code »

    This finally renames the thread_info field in task structure to stack, so that
    the assumptions about this field are gone and archs have more freedom about
    placing the thread_info structure.

    Nonbroken archs which have a proper thread pointer can do the access to both
    current thread and task structure via a single pointer.

    It'll allow for a few more cleanups of the fork code, from which e.g. ia64
    could benefit.

  • 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.

    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.

  • 3171a0305   [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem) ... Browse Code »

    Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
    timer interrupt handler with this change.

    Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
    callers of do_timer() should know how many ticks to update. Passing ticks
    get rid of this redundant calculation. Also there are another redundancy
    pointed out by Martin Schwidefsky.

    This cleanup make a barrier added by
    5aee405c662ca644980c184774277fc6d0769a84 needless. So this patch removes
    it.

    As a bonus, this cleanup make wall_jiffies can be removed easily, since now
    wall_jiffies is always synced with jiffies. (This patch does not really
    remove wall_jiffies. It would be another cleanup patch)
