[$] The return of the lockdown patches

It's been a year since we looked in on the
kernel lockdown patches; that's because things have been fairly quiet on
that front since there was a loud and
discordant dispute about them back then. But Matthew Garrett has been
posting new versions over the last two months; it would seem that the
changes that have been made might be enough to tamp down the flames and,
perhaps, even allow them to be merged into the mainline.
