Log message:
Import dt(4) a driver and framework for Dynamic Profiling.
The design is fairly simple: events, in the form of descriptors on a
ring, are being produced in any kernel context and being consumed by
a userland process reading /dev/dt.
Code and hooks are all guarded under '#if NDT > 0' so this commit
shouldn't introduce any change as long as dt(4) is disable in GENERIC.
