Subject: [PATCH 41/62] Blackfin: include system/processor info in dump messages

From: Robin Getz <robin.getz@...log.com>

People often copy & paste crash messages without surrounding context, so
include common useful information like system/processor stats in the crash
summary.  This should smooth over the report/test cycle a bit more.
