  • 83c54070e   mm: fault feedback #2 ... Browse Code »

    This patch completes Linus's wish that the fault return codes be made into
    bit flags, which I agree makes everything nicer. This requires requires
    all handle_mm_fault callers to be modified (possibly the modifications
    should go further and do things like fault accounting in handle_mm_fault --
    however that would be for another patch).

    If the kernel OOPSed or BUGed then it probably should be considered as
    tainted. Thus, all subsequent OOPSes and SysRq dumps will report the
    tainted kernel. This saves a lot of time explaining oddities in the
    calltraces.

  • 608e26196   generic bug: use show_regs() instead of dump_stack() ... Browse Code »

    The current generic bug implementation has a call to dump_stack() in case a
    WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(),
    gets called from an exception handler we can do better: just pass the
    pt_regs structure to report_bug() and pass it to show_regs() in case of a
    warning. This will give more debug informations like register contents,
    etc... In addition this avoids some pointless lines that dump_stack()
    emits, since it includes a stack backtrace of the exception handler which
    is of no interest in case of a warning. E.g. on s390 the following lines
    are currently always present in a stack backtrace if dump_stack() gets
    called from report_bug():

    [] show_trace+0x92/0xe8)
    [] show_stack+0xa0/0xd0
    [] dump_stack+0x2e/0x3c
    [] report_bug+0x98/0xf8
    [] illegal_op+0x1fc/0x21c
    [] sysc_return+0x0/0x10

  • af6f2b2b5   [AVR32] Update defconfigs ... Browse Code »

    Update defconfigs for ATNGW100 and ATSTK1002. This will enable the
    SLUB allocator by default on both, and will enable NFS root on
    ATSTK1002 (ATNGW100 had it enabled before.)

  • 6b84bbfc7   [AVR32] Initialize dma_mask and dma_coherent_mask ... Browse Code »

    The current at32ap7000 platform devices aren't declared as supporting DMA,
    so that layered drivers can't tell whether they need to manage DMA.

    This patch makes all those platform devices report that they support DMA.
    Most do, but in a few cases this is inappropriate.

    USART mapping used to be accomplished by the manual filling of
    at32_usart_map[] and at32_nr_usarts. This has now been replaced
    with at32_map_usart() so we can remove these variables.

  • ab61f7d21   [AVR32] Fix bug in invalidate_dcache_region() ... Browse Code »

    If (start + size) is not cacheline aligned and (start & mask) > (end &
    mask), the last but one cacheline won't be invalidated as it should.
    Fix this by rounding `end' down to the nearest cacheline boundary if
    it gets adjusted due to misalignment.

    Also flush the write buffer unconditionally -- if the dcache wrote
    back a line just before we invalidated it, the dirty data may be
    sitting in the write buffer waiting to corrupt our buffer later.

    Rename .taglist to .taglist.init to silence section mismatch warnings.
    The .taglist.init section was already placed in the .init output
    section along with .init.text, so the warning didn't indicate any real
    problems.

    Implement dma_alloc_writecombine() and its dma_free_writecombine()
    counterpart. These will do basically the same thing as
    dma_alloc_coherent() except that the virtual mapping will allow
    write buffering, causing better performance for certain use cases
    like frame buffers.

    The same API is already available on ARM.

    As Robert P. J. Day pointed out, the CONFIG_CPU_AT32AP7000 symbol
    wasn't used for anything. It should have been used to select the
    correct -mcpu= options for CFLAGS.

    -mcpu=ap7000 is the default anyway, so this patch shouldn't really
    make any difference, but it's always nice to do things correctly.

  • 1eeb66a1b   move die notifier handling to common code ... Browse Code »

    This patch moves the die notifier handling to common code. Previous
    various architectures had exactly the same code for it. Note that the new
    code is compiled unconditionally, this should be understood as an appel to
    the other architecture maintainer to implement support for it aswell (aka
    sprinkling a notify_die or two in the proper place)

    arm had a notifiy_die that did something totally different, I renamed it to
    arm_notify_die as part of the patch and made it static to the file it's
    declared and used at. avr32 used to pass slightly less information through
    this interface and I brought it into line with the other architectures.
