    SubjectLinuxPPS core (Version 1): the PPS Linux implementation.
    This patch adds the PPS core support into Linux.

    Currently I just propose the "core" so after inclusion we can add all
    other related stuff as suggested by several people in this list. :)

    PPS means "pulse per second" and its API is specified by RFC 2783
    (Pulse-Per-Second API for UNIX-like Operating Systems, Version 1.0).

    The code has been tested with the NTPD program
    (http://www.eecis.udel.edu/~mills/ntp/html/index.html) and several GPS
    antennae.


    Changelog
    =========

    Version [full patchset] -> 1
    ----------------------------

    * stupid filenames removed.

    * kernel-doc documentation of exported symbols.

    * old BKL-locked ioctl removed.

    * !uarg checks in the ioctls removed.

    * pps.h revisited but not splitted, since several stuff are shared between
    kernel and user land (I hope this will not stop inclusion...)

    Rodolfo
