I looked into a much, much easier "recursive dependency" warning recently. That triggered me to post http://article.gmane.org/gmane.linux.kernel/1678946 . In summary: select statements are treated as "reverse dependencies", but that is actually rather odd. See, for example, DMADEVICES in this warning: the kconfig code treats it as if it's depending on SAMSUNG_DMADEV. But I would be very surprised if that was what was intended when that select statement was added. Please note that I have not yet really looked into the mess you reported. But for now I'll state that a recursive dependency warning involving select statements is probably bogus. Perhaps Yann e.a. can prove me wrong. I might have an ugly hack to the kconfig code disabling the "recursive dependency" stuff stashed away somewhere. Not sure, as it's been two months...
