    [POWERPC] pasemi: Distribute interrupts evenly across cpus · d87bf3be
    Olof Johansson authored
    By default the OpenPIC on PWRficient will bias to one core (since that
    will improve changes of the other core being able to stay idle/powered
    down). However, this conflicts with most irq load balancing schemes,
    since setting an interrupt to be delivered to either core doesn't really
    result in the load being shared. It also doesn't work well with the
    soft irq disable feature of PPC, since EE will stay on until the first
    interrupt is taken while soft disabled.
    
    Set the gconf0 config bit that enables even distribution of interrupts
    among the two cores.
