Harald Freudenberger 4da57a2fea s390/zcrypt: extend cca_findcard function and helper
Rework and extension of the cca_findcard function to be prepared for
other types of secure key blobs. Split the function and extract an
internal function which has no awareness of key blobs any
more. Improve this function and the helper code around to be able to
check for a minimal crypto card hardware level (Background: the newer
AES cipher keys need to match to the master key verification pattern
and need to have a crypto card CEX6 or higher).

No API change, neither for the in-kernel API nor the ioctl interface.

README

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.
