- Use db_printf() instead of printf(). - Clean up decode_syscall() to use regular if-then-else rather than goto's. - Use the same method of parsing PID's for per-process traces as the x86 code does: that is, if the address passed in is not a valid kernel address, treat it is a decimal pid. - If the pid of the current process is specified, fall back to using the "default" parameters for the trace as curproc's pcb is not valid at this point.
