Dan Williams 4fb9b9e8d5 ioat: cleanup completion status reads ... The cleanup path makes an effort to only perform an atomic read of the 64-bit completion address. However in the 32-bit case it does not matter if we read the upper-32 and lower-32 non-atomically because the upper-32 will always be zero.
