Nicolai Stange 46ed5269bf crypto: kpp - provide support for KPP spawns
The upcoming support for the RFC 7919 ffdhe group parameters will be
made available in the form of templates like "ffdhe2048(dh)",
"ffdhe3072(dh)" and so on. Template instantiations thereof would wrap the
inner "dh" kpp_alg and also provide kpp_alg services to the outside again.

The primitves needed for providing kpp_alg services from template instances
have been introduced with the previous patch. Continue this work now and
implement everything needed for enabling template instances to make use
of inner KPP algorithms like "dh".

More specifically, define a struct crypto_kpp_spawn in close analogy to
crypto_skcipher_spawn, crypto_shash_spawn and alike. Implement a
crypto_grab_kpp() and crypto_drop_kpp() pair for binding such a spawn to
some inner kpp_alg and for releasing it respectively. Template
implementations can instantiate transforms from the underlying kpp_alg by
means of the new crypto_spawn_kpp(). Finally, provide the
crypto_spawn_kpp_alg() helper for accessing a spawn's underlying kpp_alg
during template instantiation.

Annotate everything with proper kernel-doc comments, even though
include/crypto/internal/kpp.h is not considered for the generated docs.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

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.
