I think it would be nice to have more platform support in .31. 
Perfcounters is a brand-new feature so there's no risk of 
regression. In the end it will depend on Linus to pull of course, 
and BenH can veto it too if he'd like no more PowerPC changes in 
this cycle. Worst-case it's all .32 material.
