Thomas Weißschuh daed646d3c KVM: s390: Don't use %pK through debug printing 
[ Upstream commit 0c7fbae5bc ]

Restricted pointers ("%pK") are only meant to be used when directly
printing to a file from task context.
Otherwise it can unintentionally expose security sensitive,
raw pointer values.

Use regular pointer formatting instead.

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 reStructuredText 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.
