From: Pekka Paalanen Date: Fri, 24 Oct 2008 17:08:11 +0000 (+0300) Subject: trace: add the MMIO-tracer to the tracer menu, cleanup X-Git-Tag: v2.6.30-rc1~2^2~309^3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fd3fdf11d3c649769e02459c5f1b8081a15e9007;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git trace: add the MMIO-tracer to the tracer menu, cleanup Impact: cleanup We can remove MMIOTRACE_HOOKS and replace it with just MMIOTRACE. MMIOTRACE_HOOKS is a remnant from the time when I thought that something else could also use the kmmio facilities.
