    aesni(4): Avoid panicking when kmalloc() returns an unaligned pointer.
    
    Instead, align it ourselves and keep the original address for kfree().
    This is a bit hacky but not too hacky (and it is done the same way in
    padlock(4)).
    
    In the middle run, we probably need some kmalloc() flavor that can do
    alignment.
