Message

The first patch fixes an oops when unloading a driver with PTP clock and
enabled virtual clocks.

The other patches add missing features to make synchronization with
virtual clocks work as well as with the physical clock.

Miroslav Lichvar (5):
  ptp: unregister virtual clocks when unregistering physical clock.
  ptp: increase maximum adjustment of virtual clocks.
  ptp: add gettimex64() to virtual clocks.
  ptp: add getcrosststamp() to virtual clocks.
  ptp: start virtual clocks at current system time.

(I don't agree with this last one)
