    I don't recall seeing this requirement mentioned before, and that's a ton
    of patches you have there.

    Please tell us a little more about why we need these patches. (Apart from
    what seems to be a moderate amount of code consolidation).

    Also, what is different between __setup and __early_setup? Why is it not
    possible to make __setup run sufficiently early for whatever application is
    requiring these changes?

    Thanks.
