Similar breakage for s390 and sparc it seems:

drivers/crypto/marvell/cesa.c:353:2: error: implicit declaration of
function 'phys_to_dma' [-Werror=implicit-function-declaration]

http://kisskb.ellerman.id.au/kisskb/buildresult/12445415/
http://kisskb.ellerman.id.au/kisskb/buildresult/12445345/

If the CESA IP is only available on a single arch then
adding an arch dependency might be the easiest fix,
since phys_to_dma seems sparsely implemented.
