It is a regression as the same "make oldconfig routine" has been working 
iirc since atleast 2.4 series kernels :)

But I dont see it as needing a "quick solution" revert if the "kconfig: 
only write '# CONFIG_FOO is not set' for visible symbols" is considered 
a "useful thing we want to keep"... I'd rather think waiting/working a 
bit for a proper fix is the better way then...

I can work around it for now (or keep the revert in our kernel builds 
for now) until it gets properly fixed...

Feel free to cc me on suggested fixes to test
