Remove the legacy device driver code for CEX2 and CEX3 cards. The last machines which are able to handle CEX2 crypto cards are z10 EC first available 2008 and z10 BC first available 2009. The last machines able to handle a CEX3 crypto card are z196 first available 2010 and z114 first available 2011. Please note that this does not imply to drop CEX2 and CEX3 support in general. With older kernels on hardware up to the aforementioned machine models these crypto cards will get support by IBM. The removal of the CEX2 and CEX3 device drivers code opens up some simplifications, for example support for crypto cards without rng support can be removed also.

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.
