This isn't really a regression -- it's been like this for years. It's a
non-functional configuration which doesn't really make sense, and would
only crop up with randconfig (or crack).
Linus was offered the patch a few weeks ago, but didn't take it -- it's
not really a priority for 2.6.23. It's in my git tree and will be pushed
when the 2.6.24 merge window opens.

You shouldn't push this even for 2.6.24 ... I can't see why/how a runtime
BUG() scores over erroring out at build-time itself. And if there is no
codepath that leads to that BUG() at runtime, then what's the point of
adding dead code ...
So I wonder if what you're actually looking for is some kind of Kconfig
dependencies that will *prevent* the kind of .config from being generated
that Ingo ran into ?

I looked at that but decided against it. There's too much hand-holding
and arbitrary 'automatic' crap in the Kconfig crap already, and I
couldn't see a way to do it that didn't make that worse.
As long as we no longer break randconfig builds, it'll be fine. It's not
as if people _run_ those kernels, let alone actually exercise the code
path in question.

Ok, I removed it from the KR list.
