    I mentioned 'make oldconfig' because there you can't get a preview of
    what other options you are perhaps about to enable or disable.

    Maybe I'm extraordinarily dumb, but I felt unable to determine for sure
    what consequences enabling or disabling some of those new prompts had
    when I ran 'make oldconfig' for the first time in a post-2.6.22 tree.

    Will saying Y merely present further options, or will it actually cause
    something to be built?

    Thanks for making an actual patch out of it and adding these other bits.

    Sure, if I disable USB now I expect that I may possibly miss
    USB_COFFEE_PAD in 2.6.47. That wouldn't worry me.

    But what about loosely defined categories like BLK_DEV, INSTRUMENTATION,
    MISC_DEVICES? What functionality will be provided by their suboptions
    in 2.6.47?
