From: Ira Weiny
kmap() and kmap_atomic() are being deprecated in favor of
kmap_local_page().
There are two main problems with kmap(): (1) It comes with an overhead
as mapping space is restricted and protected by a global lock for
synchronization and (2) it also requires global TLB invalidation

There are 3 places in namei.c where the equivalent of ext2_put_page() is
open coded. We want to use k[un]map_thread() instead of k[un]map() in
ext2_[get|put]_page().
Move ext2_put_page() to ext2.h and use it in namei.c in prep for
converting the k[un]map() code.
