As of this writing, I don't have access to a machine that has AES-NI
instructions.

Would you be willing to test code if AES-NI support is added to loop-AES?

Most of the testing would be done as unprivileged userspace program. After
it runs fine in userspace, then the code gets copied to kernel driver.
