From 9be9be2e9a966fe32c1a443c5197f829ecc3028c Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Thu, 12 Jun 2014 16:53:08 +1000 Subject: [PATCH] powerpc: Reduce scariness of interrupt frames in stack traces Some people see things like "Exception: 501" in stack traces in dmesg and assume that means that something has gone badly wrong, when in fact "Exception: 501" just means a device interrupt was taken. This changes "Exception" to "interrupt" to make it clearer that we are just recording the fact of a change in control flow rather than some error condition.
