4.7-stable review patch. If anyone has any objections, please let me know. ------------------ From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> commit b30bdfa86431afbafe15284a3ad5ac19b49b88e3 upstream. As it is if you ask for a sync gcm you may actually end up with an async one because it does not filter out async implementations of ghash. This patch fixes this by adding the necessary filter when looking for ghash.
