I'm OK with the kzalloc/memset thing, but I'd prefer to keep all those
other bits.

Yes they're superfluous, but this is init code, so nobody cares about
performance and having those things explitic makes it easier to read.

As to the very latest patch, that's there so that if/when we extend that
array we can simply continue. Also its more symmetric/consistent. Any
half sane DCE pass should get rid of it anyway, as the result is unused.
