Add -lowlatency kernel to archives

Registered by Scott Lavender on 2011-10-26

Adding the -lowlatency kernel into the universe repository will allow Ubuntu Studio users to have a tuned kernel for audio work installed by default.

This kernel will be built and maintained by the Ubuntu Studio team, therefore it presumably would be in the universe repository. Responsibilities also include rebasing the kernel for security updates and working with -security to push updates.

Etherpad notes:
Welcome to Ubuntu Developer Summit!
#uds-p #other #other-p-lowlatency

Confirm -lowlatency performance against -generic
 - coordinate testing on variety of hardware and audio interfaces

  - having real 'latency ranges' for each kernel would be very good to know if this is needed and to set expectations for the consumer

Maintenance Failover (i.e. who will maintain it)
 - Alessio A. Bogani and Scott Lavender have committed
 - probably need to identify one other person for
Build Package
 - create git branch based on ubuntu kernel on git-hub (ubuntu kernel is also mirrored on git-hub)
 - package and build -lowlatency kernel in team branch
 - submit package to REVU
ACTION: [scott-lavender] new team for the ubuntu-studio kernel
ACTION: [brad-figg] add -lowlatency as a derivative of -master so they get bugs to rebase
Security Updates
 - coordinate with jjohansen to develop plan to rebase -lowlatency for security updates
