    I think that patches [02-08/11] can be applied before the rest of the series.

    In fact, I'd like to do that and expose a forward-only branch containing them.

    Then, patches [1,09-11/11] will become a separate PCI/ACPI specific
    series that should be somewhat easier to grasp.

    What do you think?
