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.
