This patch adds low level functions, structs and defines to support CCA AES cipher keys: - struct cipherkeytoken can be used for an inside view of the CCA AES cipher key token blob. - function cca_cipher2protkey() derives an CPACF protected key from an CCA AES cipher key. - function cca_gencipherkey() generates an CCA AES cipher key with random value. - function cca_findcard2() constructs a list of apqns based on input constrains like min hardware type, mkvp values. - cca_check_secaescipherkey() does a check on the given CCA AES cipher key blob. - cca_clr2cipherkey() generates an CCA AES cipher key from a given clear key value.

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.
