From 8a1492370b493cf680b86885286f07cb9b967716 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 3 Aug 2010 11:22:21 -0700 Subject: SAMPLES: kprobe_example: Make it print something on MIPS. This KProbes example is a little useless if it doesn't print anything. For MIPS print similar messages to those produced on x86 and PPC.
