Merge config changes from the various arch configs into generic-config where there's overlapping identical configs across all architectures. If there's a single arch that is difference to the rest of the architectures that option remains in the arch specific config as it takes precedence over the generic config.
First take on the upcomming Linux 3.2 kernel. The moving of the ethernet
drivers into vendor subdirectories caused a lot of churn in config-generic, but
hopefully it's a bit cleaner now.
