Ok, sounds good. Two questions:

 - how much testing (randconfig? different architectures?) has this gotten?

 - how much does this actually improve compile times (for a "normal"
build or a "allmodconfig" one)?

It certainly sounds like the RightThing(tm) to do, but I'd like to
know that there is real actual improvements to build times and that
the pain won't be too bad...
