Hello,

This patch series adds a new driver supporting Marvell's CESA IP.
This driver addresses some limitations of the existing one.

From a performance and CPU load point of view the most important

limitation in the existing driver is the lack of DMA support, thus
preventing us from chaining crypto operations.

All applied to cryptodev.  Thanks a lot!

It seems this breaks linux-next allmodconfig on i386:

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.
