[PATCH 00/35] crypto: Provide aes-round.h and host accel

[Richard Henderson]

Inspired by Ard Biesheuvel's RFC patches for accelerating AES
under emulation, provide a set of primitives that maps between
the guest and host fragments.

There is a small guest correctness test case.

I think the end result is quite a bit cleaner, since the logic
is now centralized, rather than spread across 4 different guests.

Further work could clean up crypto/aes.c itself to use these
instead of the tables directly.  I'm sure that's just an ultimate
fallback when an appropriate system library is not available, and
so not terribly important, but it could still significantly reduce
the amount of code we carry.

I would imagine structuring a polynomial multiplication header
in a similar way.  There are 4 or 5 versions of those spread across
the different guests.

Anyway, please review.
