The output ring needs to be invalidated before enqueuing the job to SEC. While allocation of space to output ring, it should be taken care that the size is cacheline size aligned inorder to prevent invalidating valid data.

The patch also correct the method of aligning end of structs while flushing caches

Since start = align(start_of_struct), it is incorrect to assign
end = align(start + struct_size). It should instead be,
end = align(start_of_struct + struct_size).
