Public bug reported:

The following kernel config options are disabled in linux-
image-4.4.0-25-generic_4.4.0-25.44_arm64.deb and earlier. I ask that
these config options to be turned on or set to use as module so that a
kernel running on hardware that supports the instructions will use them.
These modules use module_cpu_feature_match() so it should fall back to
using the generic versions when run on hardware that does not have the
instructions.

CRYPTO_CRC32_ARM64
CRYPTO_AES_ARM64_CE
CRYPTO_AES_ARM64_CE_CCM
CRYPTO_AES_ARM64_CE_BLK

** Affects: linux (Ubuntu)
