And since 5d6be6a5 is now in Linus' tree, we need Michal's 5 patches
(at least) to be sent to Linus ASAP ...
So it appears that using select can get us into the same sort of
trouble that not including all needed header files can. Unfortunately,
savedconfig makes that much worse :-(. So anyone changing a "select X"
to "depends on X" needs to regenerate a lot of defconfigs to make sure
that there are no unforeseen consequences.
Dave, this is a bit slack of you since I reported that problem a week
ago in the net tree and yet it has not been completely fixed before you
asked Linus to pull your tree :-(
