  • f80dff9da   [ARM] 4185/2: entry: introduce get_irqnr_preamble and arch_ret_to_user ... Browse Code »

    get_irqnr_preamble allows machines to take some action before entering the
    get_irqnr_and_base loop. On iop we enable cp6 access.

    arch_ret_to_user is added to the userspace return path to allow individual
    architectures to take actions, like disabling coprocessor access, before
    the final return to userspace.

    Per Nicolas Pitre's note, there is no need to cp_wait on the return to user
    as the latency to return is sufficient.

  • 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)

  • 6a39dd622   [ARM] 3759/2: Remove uses of %? ... Browse Code »

    Patch from Daniel Jacobowitz

    The ARM kernel has several uses of asm("foo%?"). %? is a GCC internal
    modifier used to output conditional execution predicates. However, no
    version of GCC supports conditionalizing asm statements. GCC 4.2 will
    correctly expand %? to the empty string in user asms. Earlier versions may
    reuse the condition from the previous instruction. In 'if (foo) asm
    ("bar%?");' this is somewhat likely to be right... but not reliable.

    So, the only safe thing to do is to remove the uses of %?. I believe
    the tlbflush.h occurances were supposed to be removed before, based
    on the comment about %? not working at the top of that file.

    Old versions of GCC could omit branches around user asms if the asm didn't
    mark the condition codes as clobbered. This problem hasn't been seen on any
    recent (3.x or 4.x) GCC, but it could theoretically happen. So, where
    %? was removed a cc clobber was added.

  • 95ba9fb06   [ARM] Remove definition of MAX_DMA_CHANNELS to zero ... Browse Code »

    Since we now only build arch/arm/kernel/dma.c on machine types
    which set ISA_DMA_API, we don't need to define MAX_DMA_CHANNELS
    to 0 to indicate this - this definition becomes superfluous.
    Remove it.

  • 78ff18a41   [ARM] Cleanup ARM includes ... Browse Code »

    arch/arm/kernel/entry-armv.S has contained a comment suggesting
    that asm/hardware.h and asm/arch/irqs.h should be moved into the
    asm/arch/entry-macro.S include. So move the includes to these
    two files as required.

    Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h
    includes which use those facilities, and remove asm/io.h from
    kernel/process.c.

    Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm
    and arch/arm/mach-footbridge.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
