The generic code has a better chance of being merged if it actually works at least and doesn't break every platform out there that has an existing stub. It offers quite a bit of new functionality and does clean things up a bit, so it would certainly be nice to get things to use that, rather than having to duplicate all of this crap in the architectures. If it's not going to be merged, everyone will of course continue using the existing in-tree stubs (sh, ppc, etc.). It's generally advantageous to get these things working on your architecture _before_ things are merged however, as it's one less thing to catch up on after the fact. It also helps to figure out if there are issues with the current implementation by trying it out on your platform in advance, it's a lot more work to push back against it once it's already merged. The fact that no one has bothered to even compile for the platforms the generic kgdb stuff is ported to does seem to suggest that the kgdb folks aren't terribly serious about getting it merged, though.
