This is getting very offtopic... but remap_file_pages() is just like MAP_FIXED, that the address at which a page is mapped is determined by the caller, not the kernel. So coherency with other, independent mapping of the file is basically up to chance. Do we care? I very much hope not. Why do PA-RISC and friends care at all about mmap coherecy? Is it real-world problem driven or just to be safe?
