It's not -- it's actually casting 0 to __32 -- there's no cast on the
*total_size side of the comparison. However that just makes the cast
look even fishier.

OK, how about this one then?
c->busaddr = (__u32) cmd_dma_handle;
where cmd_dma_handle is a dma_addr_t (u32 or u64)
and then later:
pci_free_consistent(h->pdev, sizeof(CommandList_struct),
c, (dma_addr_t) c->busaddr);
One problem with this one is that it looks like the hardware
wants a 32-bit value for busaddr:
cciss.h: writel(c->busaddr, h->vaddr + SA5_REQUEST_PORT_OFFSET);
