It's super-fishy looking but actually I think it's OK, at least as
things stand now. As you see later from how it's freed:

this is the bus address of memory from pci_alloc_consistent(), and
since cciss never does pci_set_consistent_dma_mask(), the mask will
remain at the default 32 bits. So the driver is actually safe in
assuming that cmd_dma_handle fits into 32 bits. assuming that
