This patch overhauls and fixes code related to crypto4xx_build_pd()
* crypto4xx_build_pd() did not handle chained source scatterlist.
This is fixed by replacing the buggy indexed-access of &src[idx]
with sg_next() in the gather array setup loop.
* The redundant is_hash, direction, save_iv and pd_ctl members
in the crypto4xx_ctx struct have been removed.
- is_hash can be derived from the crypto_async_request parameter.
- direction is already part of the security association's
bf.dir bitfield.
- save_iv is unused.
- pd_ctl always had the host_ready bit enabled anyway.
(the hash_final case is rather pointless, since the ahash
code has been deactivated).
* make crypto4xx_build_pd()'s caller responsible for converting
the IV to the LE32 format.
* change crypto4xx_ahash_update() and crypto4xx_ahash_digest() to
initialize a temporary destination scatterlist. This allows the
removal of an ugly cast of req->result (which is a pointer to an
u8-array) to a scatterlist pointer.
* change crypto4xx_build_pd() return type to int. After all
it returns -EINPROGRESS/-EBUSY.
* fix crypto4xx_build_pd() thread-unsafe sa handling.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
