[PATCH v2 0/2] crypto: Enable fuzz testing for arch code

[Ard Biesheuvel <ardb+git@google.com>]

From: Ard Biesheuvel <ardb@kernel.org>

Follow-up to [0].

crc32-generic and crc32c-generic are built around the architecture
library code for CRC-32, and the lack of distinct drivers for this arch
code means they are lacking test coverage.

Fix this by exposing the arch library code as a separate driver (with a
higher priority) if it is different from the generic C code. Update the
crc32-generic drivers to always use the generic C code.

Changes since [0]:
- make generic drivers truly generic, and expose the arch code as a
  separate driver
