commit 26e00ffbeb608f43106fec96c94629dbe74e87fd
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date:   Fri May 23 15:22:11 2014 +0200

    refclock: don't include average dispersion in unfiltered samples
    
    The dispersion of refclock samples before filtering now includes only
    offset correction error and precision.
    
    This should fix a problem where locked PPS got stuck with large average
    dispersion and didn't accept new samples due failing check of offset
    and dispersion.

commit b745b6d54627a6851eccce8974263945262f7cc1
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date:   Wed May 21 14:27:50 2014 +0200

    refclock: add maxdispersion option
    
    This can be used to prevent accumulation of samples with estimated
    dispersion above given limit. By default, this limit is disabled.

commit e147f2f11e1bc208db9053fa1df05d9b4857a545

    sys: drop frequency scaling in Linux driver
    
    Since the kernel USER_HZ constant was introduced and the internal HZ
    can't be reliably detected in user-space, the frequency scaling constant
    used with older kernels is just a random guess.
    
    Remove the scaling completely and let the closed loop compensate for the
    error. To prevent thrashing between two states when the system's
    frequency error is close to a multiple of USER_HZ, stick to the current
    tick value if it's next to the new required tick. This is used only on
    archs where USER_HZ is 100 as the frequency adjustment is limited to 500
    ppm.
    
    The linux_hz and linux_freq_scale directives are no longer supported,
    but allowed by the config parser.

commit 14687d003d926e2afebba1d03336201a51045b0f
Author: Miroslav Lichvar <mlichvar@xxxxxxxxxx>
Date:   Thu May 22 15:49:11 2014 +0200

    sys: set tick_update_hz to 100 by default in Linux driver
    
    We can't reliably detect the internal kernel HZ, it may not even be
    fixed (CONFIG_NO_HZ). Use a fixed value of 100.
