The patch titled
Subject: mm-move-mremap-from-file_operations-to-vm_operations_struct-v3
has been removed from the -mm tree. Its filename was
mm-move-mremap-from-file_operations-to-vm_operations_struct-v3.patch
This patch was dropped because it was folded into mm-move-mremap-from-file_operations-to-vm_operations_struct.patch
------------------------------------------------------
From: Oleg Nesterov <oleg@xxxxxxxxxx>
Subject: mm-move-mremap-from-file_operations-to-vm_operations_struct-v3
fs/aio.c can't be compiled if CONFIG_MMU=n, filemap_page_mkwrite() is
not defined in this case. Add ifdef(CONFIG_MMU) into aio_ring_vm_ops.
Note that this only fixes the build error, currently aio doesn't work
if !CONFIG_MMU anyway.
