crypto: aead - Add new interface with single SG list
The primary user of AEAD, IPsec includes the IV in the AD in
most cases, except where it is implicitly authenticated by the
underlying algorithm.
The way it is currently implemented is a hack because we pass
the data in piecemeal and the underlying algorithms try to stitch
them back up into one piece.
This is why this patch is adding a new interface that allows a
single SG list to be passed in that contains everything so the
algorithm implementors do not have to stitch.
The new interface accepts a single source SG list and a single
destination SG list. Both must be laid out as follows:
AD, skipped data, plain/cipher text, ICV
The ICV is not present from the source during encryption and from
the destination during decryption.
For the top-level IPsec AEAD algorithm the plain/cipher text will
contain the generated (or received) IV.

crypto: nx - add hardware 842 crypto comp alg
Add crypto compression alg for 842 hardware compression and decompression,
using the alg name "842" and driver_name "842-nx".
This uses only the PowerPC coprocessor hardware for 842 compression. It
also uses the hardware for decompression, but if the hardware fails it will
fall back to the 842 software decompression library, so that decompression
never fails (for valid 842 compressed buffers). A header must be used in
most cases, due to the hardware's restrictions on the buffers being
specifically aligned and sized.
Due to the header this driver adds, compressed buffers it creates cannot be
directly passed to the 842 software library for decompression. However,
compressed buffers created by the software 842 library can be passed to
this driver for hardware 842 decompression (with the exception of buffers
containing the "short data" template, as lib/842/842.h explains).

crypto: nx - simplify pSeries nx842 driver
Simplify the pSeries NX-842 driver: do not expect incoming buffers to be
exactly page-sized; do not break up input buffers to compress smaller
blocks; do not use any internal headers in the compressed data blocks;
remove the software decompression implementation; implement the pSeries
nx842_constraints.
This changes the pSeries NX-842 driver to perform constraints-based
compression so that it only needs to compress one entire input block at a
time. This removes the need for it to split input data blocks into
multiple compressed data sections in the output buffer, and removes the
need for any extra header info in the compressed data; all that is moved
(in a later patch) into the main crypto 842 driver. Additionally, the
842 software decompression implementation is no longer needed here, as
the crypto 842 driver will use the generic software 842 decompression
function as a fallback if any hardware 842 driver fails.
