The crypt_ctl structure must be exactly 64 bytes long to work correctly, and it has to be a power-of-two size to allow turning the 64-bit division in crypt_phys2virt() into a shift operation, avoiding the link failure: ERROR: modpost: "__aeabi_uldivmod" [drivers/crypto/intel/ixp4xx/ixp4xx_crypto.ko] undefined! The failure now shows up because the driver is available for compile testing after the move, and a previous fix turned the more descriptive BUILD_BUG_ON() into a link error. Change the variably-sized dma_addr_t into the expected 'u32' type that is needed for the hardware, and reinstate the size check for all 32-bit architectures to simplify debugging if it hits again.
