Subject: mm/swap.c: clean up *lru_cache_add* functions

commit 2329d3751b082b4fd354f334a88662d72abac52d upstream.

In mm/swap.c, __lru_cache_add() is exported, but actually there are no
users outside this file.

This patch unexports __lru_cache_add(), and makes it static.  It also
exports lru_cache_add_file(), as it is use by cifs and fuse, which can
loaded as modules.
