Note, I have yet (nor anyone else) ported the new ftrace to arm. That is going to be needed soon. If you want to do it (hint hint) don't waste your time on the -rt ftrace. That will soon be revamped to get back in line with upstream ftrace, which can be found here: git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git Look for the ftrace branch. Any work on ftrace should be done against that. I will be working on getting -rt up to that version, but first I'll need to send over a few fixes to ftrace there too.
