Subject: [RFC] Add missing #include <linux/bug.h>

ARRAY_SIZE uses BUILD_BUG_ON_ZERO, which is undefined is you don't
include linux/bug.h first, which just happened to me.

Is there any reason this include isn't here? A quick grep found 595
other files using a define from bug.h without ever including it.

If this is a simple mistake and was forgotten, I can send an actual
patchset to fix this, but it feels like it was left out on purpose.

Cheers,
  Eric Engestrom

PS: If this is a cleanup that needs to be done, I might to it for other
headers as well.
