Ingo,
Please pull the perf/core branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git perf/core
Soeren reported some time ago that callchains were broken on x86_64 with cpu-clock/task-clock events. After some time I finally found the problem was in the irq low level arg saving. It touches fragile code though, I hope some people can have a look over the fix.
Thanks, Frederic ---
