commit
274252862f386b7868f35bf5ceaa5391a8ccfdf3 upstream.
This was broken by commit
7759995c75ae0cbd4c861582908449f6b6208e7a (yes,
myself). The basic problem here is since the digest state is only saved
after the last chunk, the state array is only valid when handling the
first chunk of the next buffer. Broken since linux-3.0.
