A couple of years ago Andy posted this patch series: http://thread.gmane.org/gmane.linux.kernel/1233209/
These patches have been in use at facebook for a couple of years and along with a vDSO implementation of thread_cpu_time(), they have proven useful for our profilers.
I didn't see any arguments against this patch series. Did I miss some discussion on the topic?
