I think it makes sense to expose the list and sem to cache.c.  Of
course we should change the names so that they're less generic (ie add
an "ib_" prefix) to avoid clashes if someone builds IB support into
a monolithic kernel.

Also it probably makes sense to turn device_sem into an rwsem and use
down_read() if cache.c to allow concurrent lookups by the CM.
