Hi,

I'd like the following patch to be applied to stable for versions between 4.1 and 4.10 (inclusively).

This is a minimal fix for a bug where arm32 kernels can use a much slower implementation of AES than is actually available, potentially forcing vendors to disable encryption on their devices.

Min version is 4.1 because that was the first version to include the aes-ce algorithms.

Max version is 4.10 because in 4.11, this bug was fixed incidentally as part of a complete rewrite of the bit-sliced AES implementation.

Thanks for the patch, now queued up.
