Subject: [PATCH 7/7] arc, print-fatal-signals: reduce duplicated information

From: Vineet Gupta <vgupta@...opsys.com>

After the recent generic debug info on dump_stack() and friends, arc
is printing duplicate information on debug dumps.

 [ARCLinux]$ ./crash
 crash/50: potentially unexpected fatal signal 11.	<-- [1]
 /sbin/crash, TGID 50					<-- [2]
 Pid: 50, comm: crash Not tainted 3.9.0-rc4+ #132 	<-- [3]
 ...

Remove them.

tj: Updated patch desc.
