I suspect the opinion of the ptrace maintainers matters heavily whether 
it's appropriate for v2.6.33. You are not going to maintain this, they 
are.

Regarding porting it to even more architectures - that's pretty much the 
worst idea possible. It increases maintenance and testing overhead by 
exploding the test matrix, while giving little to end result. Plus the 
worst effect of it is that it becomes even more intrusive and even 
harder (and riskier) to merge.

So dont do that.

The best strategy is to concentrate on just one or two well-tested 
architectures, and then grow to other architectures gradually. Like 
we've done it for basically all big kernel features in the past 10 years 
(that had non-trivial arch dependencies), with no exception that i can 
remember.

Thanks,
