[PATCH] double flush_page_to_ram

[Hugh Dickins]

filemap_nopage and shmem_nopage do flush_page_to_ram before returning
page, but do_no_page also does flush_page_to_ram on any page it slots
into the user address space.  It's memory.c's business, remove it from
shmem and filemap (and cut outdated comment from when filemap copied).
