I don't know whether there was a bug in the kconfig changes that has led to allowing configurations that were not meant to be legal even with the new semantics, or if the Kconfig files have simply become incorrect now and the tool works as expected. Please have a look at the cases I found, and what you think we should do about them. I assume there are a couple more like these, the six regressions here are what I found in the first 1000 randconfig builds on the kernel.
