  • 7bf02ea22   arch, mm: filter disallowed nodes from arch specific show_mem functions ... Browse Code »

    Architectures that implement their own show_mem() function did not pass
    the filter argument to show_free_areas() to appropriately avoid emitting
    the state of nodes that are disallowed in the current context. This patch
    now passes the filter argument to show_free_areas() so those nodes are now
    avoided.

    This patch also removes the show_free_areas() wrapper around
    __show_free_areas() and converts existing callers to pass an empty filter.

    ia64 emits additional information for each node, so skip_free_areas_zone()
    must be made global to filter disallowed nodes and it is converted to use
    a nid argument rather than a zone for this use case.

  • 268bb0ce3   sanitize <linux/prefetch.h> usage ... Browse Code »

    Commit e66eed651fd1 ("list: remove prefetching from regular list
    iterators") removed the include of prefetch.h from list.h, which
    uncovered several cases that had apparently relied on that rather
    obscure header file dependency.

    So this fixes things up a bit, using

    grep -L linux/prefetch.h $(git grep -l '[^a-z_]prefetchw*(' -- '*.[ch]')
    grep -L 'prefetchw*(' $(git grep -l 'linux/prefetch.h' -- '*.[ch]')

    to guide us in finding files that either need
    inclusion, or have it despite not needing it.

    There are more of them around (mostly network drivers), but this gets
    many core ones.

  • 2d06d8c49   [CPUFREQ] use dynamic debug instead of custom infrastructure ... Browse Code »

    With dynamic debug having gained the capability to report debug messages
    also during the boot process, it offers a far superior interface for
    debug messages than the custom cpufreq infrastructure. As a first step,
    remove the old cpufreq_debug_printk() function and replace it with a call
    to the generic pr_debug() function.

    How can dynamic debug be used on cpufreq? You need a kernel which has
    CONFIG_DYNAMIC_DEBUG enabled.

    To enabled debugging during runtime, mount debugfs and

    $ echo -n 'module cpufreq +p' > /sys/kernel/debug/dynamic_debug/control

    for debugging the complete "cpufreq" module. To achieve the same goal during
    boot, append

    ddebug_query="module cpufreq +p"

    as a boot parameter to the kernel of your choice.

    For more detailled instructions, please see
    Documentation/dynamic-debug-howto.txt

  • 184748cc5   sched: Provide scheduler_ipi() callback in response to smp_send_reschedule() ... Browse Code »

    For future rework of try_to_wake_up() we'd like to push part of that
    function onto the CPU the task is actually going to run on.

    In order to do so we need a generic callback from the existing scheduler IPI.

    This patch introduces such a generic callback: scheduler_ipi() and
    implements it as a NOP.

    BenH notes: PowerPC might use this IPI on offline CPUs under rare conditions!
