    Turbostat: reorganise metric names
    
    The `plugin_instance` now always is the hardware element
    (cpuNN/coreNN/pkgNN) the data belongs to. Any optional identifier string
    is moved to the `type_instance`.
    
    Also remove the "_W" unit suffix as the "power" `type` implies we're
    dealing with Watts.
    
    The idea is to have the naming scheme in line with the way most other
    plugins usually organise data.

    The previous way of doing worked as expected, but didn't print out
    anything in the summary, making it difficult to know why the plugin
    wasn't built on older systems.

    These options should only be used to turn off unwanted features

    Turbostat: relax dependency on invariant TSC
    
    Backport d7899447535929b3672442b7b42a09ae4e48fa91
    from Len Brown <len.brown at intel.com>
    
    Turbostat can be useful on systems that do not support invariant TSC,
    so allow it to run on those systgems.
    
    All arithmetic in turbostat using the TSC value is per-processsor,
    so it does not depend on the TSC values being in sync acrosss
    processors.
    
    Turbostat uses cdtime() for the measurement interval
    rather than using the TSC directly, so that key metric
    is also immune from variable TSC.
    
    Turbostat has a TSC sanity check gauge:
    TSC_MHz = TSC_delta/interval
    
    If this column is constant and is close to the processor
    base frequency, then the TSC is behaving properly.
    
    The other key turbostat columns are calculated this way:
    Avg_Mhz = APERF_delta/interval
    Bzy_MHz = TSC_delta/APERF_delta/MPERF_delta/interval
    c0 = MPERF_delta/TSC_delta
    
    This adaptation of the original commit has not been tested on any
    old CPU. This patch also re-introduce the boolean "do_smi" as such
    old CPUs don't have SMI.

    Turbostat: Add (back) sanity check
    
    This new gauge contains TSC / interval_float.
    If TSC and interval_float are behaving correctly, this is supposed to be
    constant. Otherwise, other measurements can be wrong

    Turbostat: frequency add Averange, rename Buzy
    
    Partial backport of fc04cc67ea8f44124f048832a745a24bc2fa12fa
    from Len Brown <len.brown at intel.com>
    
    Add Avg_MHz column, which is the frequency that many
    users expect to see -- the total number of cycles executed
    over the measurement interval.
    
    People found the previous GHz to be confusing, since
    it was the speed only over the non-idle interval.
    That measurement has been re-named Bzy_MHz.

    Turbostat plugin: relax dependency on root
    
    Backporting commit 98481e79b60a50d699b79292ff1b7e56e7fa8425
    from Len Brown <len.brown at intel.com>
    
    For turbostat to run as non-root, it needs to permissions:
    
    1. read access to /dev/cpu/*/msr
            via standard user/group/world file permissions
    
    2. CAP_SYS_RAWIO
            eg.  # setcap cap_sys_rawio=ep $(which collectd)
    
    Yes, running as root still works.

    turbostat: Backport 'Drop temperature checks'
    
    The Intel 64 and IA-32 Architectures Software Developer's Manual says
    that TjMax is stored in bits 23:16 of MSR_TEMPERATURE TARGET (0x1a2).
    That's 8 bits, not 7, so it must be masked with 0xFF rather than 0x7F.
    
    The manual has no mention of which values should be considered valid,
    which kind of implies that they all are. Arbitrarily discarding values
    outside a specific range is wrong. The upper range check had to be
    fixed recently (commit 144b44b1) and the lower range check is just as
    wrong. See bug #75071:
    
    https://bugzilla.kernel.org/show_bug.cgi?id=75071
    
    There are many Xeon processor series with TjMax of 70, 71 or 80
    degrees Celsius, way below the arbitrary 85 degrees Celsius limit.
    There may be other (past or future) models with even lower limits.
    
    So drop this arbitrary check. The only value that would be clearly
    invalid is 0. Everything else should be accepted.
    
    After these changes, turbostat is aligned with what the coretemp
    driver does.

    Turbostat: Fix sched affinity mess
    
    get_msr doesn't need to be run on the CPU targetted. However, when run
    on another CPU, perfomances will decrease as task have to be scheduled
    on another CPU. Migrating to another CPU during the setup (where only a
    few get_msr are done) is probably not worth it. However, in the
    get_counters function, the large number of get_msr query makes it
    potentially important.
    
    This patch also introduce the restoration of the scheduling affinity as
    it was before the plugin invocation.

    Turbostat: Refactor migrate CPU before get_MSR
    
    In two out of three "get_msr" calls, there is a CPU migration, which
    does not seem to be used by something else (in one case, it was used by
    the rdtsc call).
    Move the migrate call directly into the open_msr function

    processes: Solaris: Consistently use long to represent a pid
    
    pid_t may be defined as an int or a long depending on circumstances.
    Use a long everywhere so we don't have to fiddle with typecasts.
    
    This fixes an issue where an incorrect printf format string would
    be used for a pid_t in 32-bit builds.

    to the one in swap.c.

    zfs_arc: Don't spam the log if we fail to read the "l2_size" kstat value.
    
    The value got lost with some patch to Solaris 10 and has only reappeared
    recently in 11.2. If we ever fail to read this value, stop trying, so we
    don't report an error on every interval.
