    The patchset is meant to be pretty stable, not so much a testing ground.
    Main differences from mainline are:

    1. Better performance & resource consumption, particularly on larger machines.
    2. Diagnosis tools (kgdb, early_printk, etc).
    3. Kexec support.
    4. ivtv drivers

    I'd be very interested in feedback from anyone willing to test on any
    platform, however large or small.
