[Bug 1594455] Re: enable CRC32 and AES ARM64 by default or as module


Installed kernel and ran perf top -z while filtered on symbols
containing "crc32".  I see the symbol crc32c_arm64_le_hw instead of
__crc32_le on hardware with CRC32 instruction support, so the change to
the kernel is working.  Thank you.

  enable CRC32 and AES ARM64 by default or as module

Bug description:
  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.
