[PATCH]fix xentrace
...trace buffer is initialized or not.
If not, the trace buffer is initialized by using this patch.
This is avoiding following message.
ERROR: Failure to get trace buffer pointer from Xen (22 = Invalid argument)
This routine is based on the specification of
the trace buffer control function trace.c/tb_control().
The function checks the trace buffer is initialized or not
in line 183.
If not, this routine stops working.
Of course, this problem is also solved by using tbctl [0|1].
But this problem is already solved by xenmon.py without using tbctl command.
This code is just moved from
tools/xenmon/xenb...
