Hmm... This is a good idea, but then, IMO, the better is to just jump the API
version to 2.32 - or - even better - to 2.6.32. This will avoid any further
sync issues in the future.

Anyway, we had several changes at the spec between the last version and the
2.6.32 version (at least 3 of them having a revision increment).

Hmm... I tried to reach you at IRC. As you weren't there anymore, I've assumed
you've already sleeping ;) As I want to finish the pending PULL requests today,
I've merged it as-is (just removing the revision update hunk) and added a patch
at the end of the series properly fixing the docs, and including the proper
changes documentation at compat.sgml.

Cheers,
Mauro
