Alexander Gordeev 7a04d491ed s390/kexec: turn DAT mode off immediately before purgatory 
The kernel code is not guaranteed DAT-off mode safe.
Turn the DAT mode off immediately before entering the
purgatory.

Further, to avoid subtle side effects reset the system
immediately before turning DAT mode off while making
all necessary preparations in advance.

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.
