It's entirely a kernel library functionality. The library intercepts all 
the places a new thread begins and makes a function call with the first 
argument being a small, newly allocated array.

For the rest of the life of that thread, then, that array can be fetched 
with i.e. call_trace()[1][TRACE_FIRSTARG] and its contents modified. No 
driver support is required, apart from the call_trace() kfun of course.
