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
herefore, replace kmap() with kmap_local_page() in hostfs_kern.c, it
