When compile-testing on other architectures, we get lots of warnings about incorrect format strings, like: drivers/dma/iop-adma.c: In function 'iop_adma_alloc_slots': drivers/dma/iop-adma.c:307:6: warning: format '%x' expects argument of type 'unsigned int', but argument 6 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] drivers/dma/iop-adma.c: In function 'iop_adma_prep_dma_memcpy': >> drivers/dma/iop-adma.c:518:40: warning: format '%u' expects argument of type 'unsigned int', but argument 5 has type 'size_t {aka long unsigned int}' [-Wformat=] Use %zu for printing size_t as required, and cast the dma_addr_t arguments to 'u64' for printing with %llx. Ideally this should use the %pad format string, but that requires an lvalue argument that doesn't work here.
