In my testing it resulted in nearly the exact config files for rawhide kernels (I tested both debugbuildsenabled 0 and 1). There are two exceptions: CONFIG_MAC80211_MESSAGE_TRACING and CONFIG_EDAC_DEBUG are now enabled in the debugbuildsenabled 0 case (e.g. when a normal rawhide kernel is build). That's afaics how it was meant -- but the Makefile missed perl calls to enable these options this case.

Looks ok to me.

Very rarely. But we can do it by hand when necessary.  no point in uglying up the spec even further.

 > How does the patch (against master) look to you guys? Did I miss anything that is needed? Please note that all the changes the patch does to the config-foo files are just those that a "make release" does now. And a lot of stuff is removed from the Makefiles, hence the patch looks big.

Let's try this out in master, and if it works out ok, we can do the same thing in
older releases when we rebase.
