I thought this driver is useless because ARMv8 CE is an order of magnitude faster. - Eric

This driver registers its algorithms with too high of a priority, which makes it get used when it shouldn't be. I've sent out a patch to fix that. - Eric

This driver will soon be getting more features so show it some refactoring love in the meantime. Switching to using a workqueue and sleeping locks improves cryptsetup benchmark results for AES encryption.
