DTrace code putback

Woohoo! The code's officially been putback. Note that the putback actually incorporates three bugs:
6325485 A stddev() aggregator would be a nice adjunct to avg()
6618705 p*d123 doesn't cause pid probes to be created
6624541 dtrace aggregations should assume signed arguments

Thanks to Jon Haslam for sponsoring it, Jon and Adam Leventhal for rigorous code reviews, and Bryan Cantrill for approving the request to integrate.

Hey Chad, great job! Thanks again. (now tell me when you're planning your next putbacks)
Hi Chad,

thanks for stddev(), I think it's really an enabling function for many tasks.
Do you have any idea when stddev() will propagate back to Solaris? Can you imagine a patch to add stddev() to older Solaris versions?

That's something to take up with the Solaris sustaining organization. Feel free to post to the DTrace discussion forum over on
thanks for all admin
information is the most beautiful treasures
