Hi Ingo,
This pull request integrate one cleanup/fix for ftrace and an update for syscall tracing: the migration from old-style tracer to individual tracepoints/trace_events and the support for perf counter.
I've tested it with success either with ftrace (every syscall tracepoints enabled at the same time without problems) and with perfcounter.
May be one drawback: it creates so much trace events that the ftrace selftests can take some time :-)
Thanks, Frederic.
