Add KMSAN support for the s390 implementations of the string functions.
Do this similar to how it's already done for KASAN, except that the
optimized memset{16,32,64}() functions need to be disabled: it's important
for KMSAN to know that they initialized something.
The way boot code is built with regard to string functions is problematic,
since most files think it's configured with sanitizers, but boot/string.c
doesn't. This creates various problems with the memset64() definitions,
depending on whether the code is built with sanitizers or fortify. This
should probably be streamlined, but in the meantime resolve the issues by
introducing the IN_BOOT_STRING_C macro, similar to the existing
IN_ARCH_STRING_C macro.

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.
