  • This adds freefall handling to hp_accel driver. According to HP, it
    should just work, without us having to set the chip up by hand.

    hpfall.c is example .c program that parks the disk when accelerometer
    detects free fall. It should work; for now, it uses fixed 20seconds
    protection period.

  • This adds a driver to the accelerometer sensor found in several HP
    laptops (under the commercial names of "HP Mobile Data Protection System
    3D" and "HP 3D driveguard"). It tries to have more or less the same
    interfaces as the hdaps and other accelerometer drivers: in sysfs and as
    a joystick.

    This driver was first written by Yan Burman. Eric Piel has updated it
    and slimed it up (including the removal of an interface to access to the
    free-fall feature of the sensor because it is not reliable enough for
    now). Pavel Machek removed few more features and switched locking from
    semaphore to mutex.

    Several people have contributed to the database of the axes.
