I guess DMA_32BIT_MASK is OK?
If that's semantically what the 0xffffffff means then yes.
It means "select lower 32 bits, because the other 32 bits are
elsewhere." Since its an arg to cpu_to_le32() I suppose there is an
implicit truncation in there, but I add such masking myself to my own
code. Makes it more clear to the reader what's going on, IMO.
Its not quite what DMA_32BIT_MASK intends, either, IMO.
