Ilya Leoshkevich f93b76958a linux-user: Passthrough MADV_DONTNEED for certain file mappings ... This is a follow-up for commit 892a4f6a75 ("linux-user: Add partial support for MADV_DONTNEED"), which added passthrough for anonymous mappings. File mappings can be handled in a similar manner. In order to do that, mark pages, for which mmap() was passed through, with PAGE_PASSTHROUGH, and then allow madvise() passthrough for these pages. Drop the explicit PAGE_ANON check, since anonymous mappings are expected to have PAGE_PASSTHROUGH anyway. Add PAGE_PASSTHROUGH to PAGE_STICKY in order to keep it on mprotect().
