Both patches are:
Reviewed-by: Kenneth Graunke <kenneth at whitecape.org>

For what it's worth, RSR, RSL, and DPA2 are mentioned in the "Defeatured 
Instructions" section of the 965 PRM, Volume 4:

"The following instructions are removed from Gen4 implementation mainly
  due to implementation cost/schedule reasons.  They are candidates for
  future generations."

So they never actually existed; the Gen4 architects just thought they 
might be useful someday...and never implemented them.
