David S. Miller ef201bebe5 sparc64: Fix rwsem constant bug leading to hangs.
As noticed by Linus, it is critical that some of the
rwsem constants be signed.  Yet, hex constants are
unsigned unless explicitly casted or negated.

The most critical one is RWSEM_WAITING_BIAS.

This bug was exacerbated by commit
424acaaeb3 ("rwsem: wake queued readers
when writer blocks on active read lock")
