NFS: Kill the "defined but not used" compile error on nommu machines
Bryan Wu reports that when compiling NFS on nommu machines he gets a "defined but not used" error on nfs_file_mmap(). The easiest fix is simply to get rid of the special casing in NFS, and just always call generic_file_mmap() to set up the file. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
