I don't really understand the AES stuff but there's something else I
noticed: if you build a kernel with the crypto stuff and run it on an
implementation that does not have the crypto extensions, there does not
seem to be any check for not using these algorithms (or falling back to
the generic implementation). Does the kernel end up with undef faults?
