The kernel gets definition-vs-declaration confused in several places.

I'd say that s/declare/define/ at such a late stage in the semaphore's
lifetime would be of dubious value.  But getting "MUTEX" out of that
macro's name would be a very good thing - it's a bad overlap with struct
mutex.  Send patch :)
