commit 49b9258b05b97c6464e1964b6a2fddb3ddb65d17 upstream.
As QCE is an order of magnitude slower than the ARMv8 Crypto Extensions on the CPU, and is also less well tested, give it a lower priority. Previously the QCE SHA algorithms had higher priority than the ARMv8 CE equivalents, and the ciphers such as AES-XTS had the same priority which meant the QCE versions were chosen if they happened to be loaded later.
