    CRED: Separate task security context from task_struct

    I think.

    It's way too large to be inlined anyway.

    Dunno if this needs an EXPORT_SYMBOL() yet.

  • Bye-bye Performance Counters, welcome Performance Events!

    In the past few months the perfcounters subsystem has grown out its
    initial role of counting hardware events, and has become (and is
    becoming) a much broader generic event enumeration, reporting, logging,
    monitoring, analysis facility.

    Naming its core object 'perf_counter' and naming the subsystem
    'perfcounters' has become more and more of a misnomer. With pending
    code like hw-breakpoints support the 'counter' name is less and
    less appropriate.

    All in one, we've decided to rename the subsystem to 'performance
    events' and to propagate this rename through all fields, variables
    and API names. (in an ABI compatible fashion)

    The word 'event' is also a bit shorter than 'counter' - which makes
    it slightly more convenient to write/handle as well.

    Thanks goes to Stephane Eranian who first observed this misnomer and
    suggested a rename.

    User-space tooling and ABI compatibility is not affected - this patch
    should be function-invariant. (Also, defconfigs were not touched to
    keep the size down.)

    This patch has been generated via the following script:

    FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

    sed -i \
    -e 's/PERF_EVENT_/PERF_RECORD_/g' \
    -e 's/PERF_COUNTER/PERF_EVENT/g' \
    -e 's/perf_counter/perf_event/g' \
    -e 's/nb_counters/nb_events/g' \
    -e 's/swcounter/swevent/g' \
    -e 's/tpcounter_event/tp_event/g' \
    $FILES

    for N in $(find . -name perf_counter.[ch]); do
    M=$(echo $N | sed 's/perf_counter/perf_event/g')
    mv $N $M
    done

    FILES=$(find . -name perf_event.*)

    sed -i \
    -e 's/COUNTER_MASK/REG_MASK/g' \
    -e 's/COUNTER/EVENT/g' \
    -e 's/\/event_id/g' \
    -e 's/counter/event/g' \
    -e 's/Counter/Event/g' \
    $FILES

    ... to keep it as correct as possible. This script can also be
    used by anyone who has pending perfcounters patches - it converts
    a Linux kernel tree over to the new naming. We tried to time this
    change to the point in time where the amount of pending patches
    is the smallest: the end of the merge window.

    Namespace clashes were fixed up in a preparatory patch - and some
    stylistic fallout will be fixed up in a subsequent patch.

    ( NOTE: 'counters' are still the proper terminology when we deal
    with hardware registers - and these sed scripts are a bit
    over-eager in renaming them. I've undone some of that, but
    in case there's something left where 'counter' would be
    better than 'event' we can undo that on an individual basis
    instead of touching an otherwise nicely automated patch. )

  • This is in preparation of the big rename, but also makes sense
    in a standalone way: 'list_entry' is a bad name as we already
    have a list_entry() in list.h.

    Also, the 'counter list' is too vague, it doesnt tell us the
    purpose of that list.

    Clarify these names to show that it's all about the group
    hiearchy.

  • Commit 5622f295 ("x86, perf_counter, bts: Optimize BTS overflow

    added a regs parameter to perf_counter_overflow(). This breaks the

    arch/powerpc/kernel/perf_counter.c: In function 'record_and_restart':
    arch/powerpc/kernel/perf_counter.c:1165: error: unknown field 'regs' specified in initializer

    This adjusts arch/powerpc/kernel/perf_counter.c to correspond with the

  • On an AMD-64 system the processor frequency that is printed during
    system boot, may be different than the tsc frequency that was
    returned by the hypervisor, due to the value returned from
    calibrate_cpu.

    For debugging timekeeping or other related issues it might be
    better to get the tsc_khz value returned by the hypervisor.

    The patch below now prints the tsc frequency that the VMware
    hypervisor returned.

  • While these don't get actively used (afaict), it still doesn't hurt
    for them to properly reflect what how respective segments will get
    mapped/ accessed.
