The patches, mostly in the vein of annotations, have been flowing upstream gradually. The reasons for it not being included last time were due to Linus objecting to the unwinder accessing stack data and assuming it was trusted. I'm not sure if those objections have been addressed yet.
The situation didn't change, since - afaik - no-one made another try. The original authors (Andi Kleen and me) were told very clearly back then by Linus that he won't accept another attempt by them to get these changes merged, no matter what (i.e. in particular independent on the fact we didn't have any problem with it in our kernels - any issues I recall we had were the result of broken manually generated unwind annotations [i.e. to assembly code, iow where the compiler wasn't to blame, which was one of Linus' main concerns apart from the question of stack accesses that Jeff mentioned]). So someone else would need to step up and perhaps first thing sort out the political aspects.
