Currently tracing is enabled from inside xmon, which may cause some
noise into the tracing buffer, and makes it harder to find what, in
the tracing buffer, are kernel non-xmon functions and what is xmon
'noise' (as printk()s and terminal functions tracing).
This patch simple disables it by default, showing a better trace output
of the failing functions just before it gets into xmon.
