[GIT PULL] tracing: Syscalls trace events + perf support

[Frederic Weisbecker <fweisbec@gmail.com>]

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.
