This series further reduces size of the hook arrays by only resevering space
for the hooks that are implemented/supported (e.g., arp only supports 3 different
hook points as it lacks PRE/POST_ROUTING).
Furthermore, add #ifdef guard to not declare arp/bridge/decnet hooks unless
they are needed.
At least Fedora has CONFIG_DECNET=n so this even reduces size for some
distro kernels.
I ran a few randconfig builds last night and it did not catch any
build errors.
See individual patches for changes since v2.
