      o KBuild Update
          + As options are moved from make-kernel.sh to Kbuild more
            warnings were apparent in the gcc build (which is unacceptable)
          + Mark suggested that testing can be done with the cc-option
            unit test to make this easier

          + Octa patch updated by Randy and Pipacs


      o Raspberry-Pi Update

              # Demos of clang kernel (laptop, rpi, android phone
                (cyanogen), etc)
          + JSM is talking at FOSDEM
          + Perhaps a LWN article would be a good idea.

              # Relatively few patches now
      o Review bug list (please update your bugs on the website before
        the meeting)
