Hi Ard,
I have tested this patch set applied to 4.15-rc7 running in a model.

I used the following tcrypt modes:
48, 49, 50, 51, 111, 112, 113, 114, 187, 188, 322, 323, 324, 325, 418,
419, 420 and 421.

Also, I added some logic to double check that sha3_ce_transform(.)
was being called rather than sha3_scalar_transform(.).
(Because both the scalar and ce code paths are contained in the
sha3-x-arm64 drivers).

So, please feel free to add for the series:
Tested-by: Steve Capper <steve.capper at arm.com>

Cheers,
