Harald Freudenberger 4bc123b18c s390/zcrypt: Add low level functions for CCA AES cipher keys
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.
