From: Oleg Nesterov <oleg@xxxxxxxxxx>
Subject: mm-move-mremap-from-file_operations-to-vm_operations_struct-fix
fs/aio.c can't be compiled if CONFIG_MMU=n, filemap_page_mkwrite()
is not defined in this case. Add yet another "must not be called"
helper into nommu.c to make the linker happy.
I still think this is pointless, afaics sys_io_setup() simply can't
succeed if CONFIG_MMU=n. Instead we should make CONFIG_AIO depend
on CONFIG_MMU.
