    Another update: I've now did what I've described as TODO above. That
    means I have everything working to parallelize the (whole) init-system
    regardless the arch or DT/ACPI or whatever.

    Cleaning up the new stuff to post it here will need some time. And
    collecting the _mandatory_ dependencies to parallelize all static linked
    drivers (from all initcall levels) will need much more time. Even on
    systems where most stuff is build as a module, the list of drivers
    initialized through initcalls is usually several dozens or even
    hundreds. You might use 'grep initcall_ System.map | wc -l' to get an idea.

    Therefor I don't know when I will post cleaned up patches and/or some
    benchmark times. The interest seems rather low.

    Regards,

    Alexander Holler
