X-Git-Tag: v2.6.36-rc1~563^2~12 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8a1492370b493cf680b86885286f07cb9b967716;p=platform%2Fupstream%2Fkernel-adaptation-pc.git 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.
