Subject: [PATCH v3 01/11] ARC: set level of log per CPU during boot to be info level

From: Noam Camus <noamca@...lanox.com>

Now it can be hidden by passing higher loglevel sevirity at cmdline
The reasons are:
1) speeding up boot time, becomes critical for many CPUs machine,
   e.g. NPS400 with 4K CPUs
2) shorten kernel log at boot time, again easy to scan for large
   scale machines such NPS400
