    [PATCH] x86-64: Revert timer routing behaviour back to 2.6.16 state · e70ea8c0
    Andi Kleen authored
    By default route the 8254 over the 8259 and only disable
    it on ATI boards where this causes double timer interrupts.
    
    This should unbreak some Nvidia boards where the timer doesn't
    seem to tick of it isn't enabled in the 8259. At least one
    VIA board also seemed to have a little trouble with the disabled
    8259.
    
    For 2.6.20 we'll try both dynamically without black listing, but I think
    for .19 this is the safer approach because it has been already well tested
    in earlier kernels. This also makes the x86-64 behaviour the same
    as i386.
    
    Command line options can change all this of course.
