History
KATO Takenori b69aa7f11a Do not set the uppervp to NULLVP in union_removed_upper. If lowervp 
is NULLVP, union node will have neither uppervp nor lowervp.  This
causes page fault trap.

The union_removed_upper just remove union node from cache and it
doesn't set uppervp to NULLVP.  Since union node is removed from
cache, it will not be referenced.

The code that remove union node from cache was copied from
union_inactive.
