AUDIT_TTY_*ET went into mainline directly and I'd missed the conflict with
the numbers already in use by audit-subtree patches. I *had* noticed when
pushing audit-subtree to -mm, swore at myself and renumbered those. Alas,
there's userland to deal with.
* auditctl has subtree support merged
* auditctl still doesn't have tty... support merged
* it's built with numbers matching the original patchset (1014/1015)
and binaries are released
* audit-subtree patchset is in RH beta kernel, also released

Vote of auditctl maintainer had been "renumber tty_...* until it's too late,
since that's the one userland doesn't support yet". The author of tty patches
agrees (see above) and I also think that this is the best way out of that mess.

Again, it's largely my fault - I'd missed the conflict in the first place and
hadn't reacted immediately.
