    The site-specific OOM messages are unnecessary, because they
    duplicate the MM subsystem generic OOM message. For example,
    k.alloc and v.alloc failures use dump_stack().

    None of these files are actually using any __init type directives
    and hence don't need to include . Most are just a
    left over from __devinit and __cpuinit removal, or simply due to
    code getting copied from one driver to the next.

  • 63fbbc169   watchdog: sp805_wdt.c: use clk_prepare_enable and clk_disable_unprepare ... Browse Code »

    Clk_prepare_enable and clk_disable_unprepare combine clk_prepare and
    clk_enable, and clk_disable and clk_unprepare. They make the code more
    concise, and ensure that clk_unprepare is called when clk_enable fails.

    A simplified version of the semantic patch that introduces calls to these
    functions is as follows: (http://coccinelle.lip6.fr/)

    //

    Pull ARM updates from Russell King:
    "Here's the updates for ARM for this merge window, which cover quite a
    variety of areas.

    There's a bunch of patch series from Will tackling various bugs like
    the PROT_NONE handling, ASID allocation, cluster boot protocol and
    ASID TLB tagging updates.

    We move to a build-time sorted exception table rather than doing the
    sorting at run-time, add support for the secure computing filter, and
    some updates to the perf code. We also have sorted out the placement
    of some headers, fixed some build warnings, fixed some hotplug
    problems with the per-cpu TWD code."

  • bb558dac6   watchdog: sp805: Fix section mismatch in ID table. ... Browse Code »

    The AMBA ID table is marked as __initdata, yet it is referenced by the
    driver struct which is not. This causes a (somewhat unhelpful) section
    mismatch warning:

    WARNING: drivers/watchdog/sp805_wdt.o(.data+0x4c): Section mismatch in
    reference from the variable sp805_wdt_driver to the (unknown
    reference) .init.data:(unknown)

    Fix this by removing the annotation.

  • 081d83a33   watchdog: sp805: Flush posted writes in enable/disable. ... Browse Code »

    There are no reads in these functions, so if MMIO writes are posted,
    the writes in enable/disable may not have completed by the time these
    functions return. If the functions run from different CPUs, it's
    in theory possible for the writes to be interleaved, which would be
    disastrous for this driver.

    At the very least, we need an mmiowb() before releasing the lock, but
    since it seems desirable for the watchdog timer to be actually stopped
    or reset when these functions return, read the lock register to force
    the writes out.

  • da3e51502   watchdog: sp805: Don't write 0 to the load value register. ... Browse Code »

    At least on the Versatile Express' V2M, calling wdt_disable followed by
    wdt_enable, for instance by running the following sequence:

    echo V > /dev/watchdog; echo V > /dev/watchdog

    results in an immediate reset. The wdt_disable function writes 0 to the
    load register; while the watchdog interrupts are disabled at this point,
    this special value is defined to trigger an interrupt immediately. It
    appears that in this instance, the reset happens when the interrupts
    are subsequently enabled by wdt_enable.

    Putting in a short delay after writing a new load value in wdt_enable
    solves the issue, but it seems cleaner to simply never write 0 to the
    load register at all: according to the hardware docs, writing 0 to the
    control register suffices to stop the counter, and the write of 0 to
    the load register is questionable anyway since this register resets to
    0xffffffff.
