copied target/linux/x86/config-3.14 and target/linux/x86/patches-3.14 to 3.18 equivalents and then tweaked until it built. Tested on alix2, soekris net4826 and soekris net4521. Still having trouble with net4826 booting from Grub, alix2 and net4521 are fine. Signed-off-by: Russell Senior <russell@personaltelco.net> SVN-Revision: 44758
