[$] Super long-term kernel support

Some years ago, prominent community leaders doubted that even short-term stable maintenance of kernel releases was feasible. Morerecently, selecting an occasional kernel for a two-year maintenance cyclehas become routine, and some kernels, such as 3.2 under the care of BenHutchings, have received constant maintenance for as much as six years. Buteven that sort of extended maintenance is not enough for some use cases, asYoshitake Kobayashi explained in his Embedded Linux Conference talk. Tomeet those needs, the CivilInfrastructure Platform (CIP) project is setting out to maintain releases for a minimum of 20 years.
