Linux 2.6.21 defines different macros for __attribute__ which are also used inside batman-adv. The next version of checkpatch.pl warns about the usage of __attribute__((packed))).
Linux 2.6.33 defines an extra macro __always_unused which is used to assist source code analyzers and can be used to removed the last existing __attribute__ inside the source code.
