mm/filemap.c: provide dummy filemap_page_mkwrite() for NOMMU
Building orangefs on MMU-less machines now results in a link error because of the newly introduced use of the filemap_page_mkwrite() function: ERROR: "filemap_page_mkwrite" [fs/orangefs/orangefs.ko] undefined! This adds a dummy version for it, similar to the existing generic_file_mmap and generic_file_readonly_mmap stubs in the same file, to avoid the link error without adding #ifdefs in each file system that uses these.
