	* process.c (process_lookup_symbol): If the address is 0x01, treat
	as kernel, regardless of whether we have a map for that address or
	not.

	* module/sysprof-module.c (timer_notify): Take a stack trace of
	the current process, even when we are in kernel mode. This way we
	can assign kernel activity to individual user space stacktraces.

	* TODO: updates.
