Move the config option to the bottom of the file - this could be a nice place also for future "selectable" config symbols. Fix up all users to drop the dependency on NET now that it is not required to supress warnings for non-NET builds. Reported-by: Linus Torvalds Signed-off-by: Sam Ravnborg --- Did a few "make ARCH=xxx allnoconfig" and no warning were triggered.
