Sorry to nitpick again and not catching it earlier, but are you sure it works this way? Normally the options in Kconfig are not prefixed with CONFIG_* So config UNALIGNED_EXPENSIVE
would be likely correct

For my part, I will apply the patch to drivers/net/tg3.c, which is fine, and will let the arch/ia64/Kconfig patch go through normal channels (since ia64 seems to be flowing these days).
