Patches 1 and 2 update the vDSO reference parser. Despite the late submission, this might be 3.16 material: it's just documentation. If I'd been more on top of this, I would have done it for 3.15. It's also probably worthwhile given that there is at least one rather buggy vDSO parser in the wild.
Patch 3 makes "Hello world" as built by Go stop segfaulting. It's a performance regression for Go programs: it causes them to stop finding any symbols in the vDSO, but that's a lot better than segfaulting. It has big-endian issues, though, and it's ugly, and it should probably be disabled for x32.
