Lorenzo Stoakes 7e8c8fd348 tools: testing: add simple __mmap_region() userland test
Introduce demonstrative, basic, __mmap_region() test upon which we can
base further work upon moving forwards.

This simply asserts that mappings can be made and merges occur as
expected.

As part of this change, fix the security_vm_enough_memory_mm() stub which
was previously incorrectly implemented.

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.
