Modified files:

sys/ia64/include unwind.h
Log:
Add logic to trace across/over a trapframe. We have ABI markers in
our unwind information for functions that are entry points into the
kernel. When stepping to the next frame, the unwinder will let us
know when sych a marker was encountered. We use this to stop the
current unwind session, query the trapframe and restart a new
unwind session based on the new trapframe.
The implementation is a bit sloppy, but at this time there are
bigger fish to fry.
