This has all changed. We no longer carry ABI information or scripts in the trees. We still do ABI checks but it's done by SWM as part of the kernel SRU process.

Thanks @juergh , that's very helpful.
So in theory we should deprecate the Wiki?

Are you aware of any other content that is relevant to ABI? I only see references to it but no explanation.
