Add a regression test to ensure that kmsan_unpoison_memory() works the same as an unpoisoning operation added by the instrumentation. The test has two subtests: one that checks the instrumentation, and one that checks kmsan_unpoison_memory(). Each subtest initializes the first byte of a 4-byte buffer, then checks that the other 3 bytes are uninitialized.

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.
