Use dma_addr_t for DMA address parameters and u32 for shared memory offset parameters.
Do not assume that dma_addr_t is the same as unsigned long; it will
not be in PAE configurations. Truncate DMA addresses to 32 bits when
printing them. This is OK because the DMA mask for this device is
32-bit (per default).
Compile-tested only.

If at first you don't succeed, you're doing about average.
