a set of helper routines to deal with real-time clocks. The generic functions access the clock diver using a kobj interface. This is intended to reduce code reduplication and make it easy to support more than one clock model on a single architecture. This code is currently only used on sparc64, but it is planned to convert the code of the other architectures to it later.
