commit80da44c29dupstream. This patch changes the p8_ghash driver to use ghash-generic as a fixed fallback implementation. This allows the correct value of descsize to be defined directly in its shash_alg structure and avoids problems with incorrect buffer sizes when its state is exported or imported.
