André Almeida 2951dddef0 selftest/futex: Reintroduce "Memory out of range" numa_mpol's subtest
Commit d8e2f91999 ("selftests/futex: Fix some futex_numa_mpol
subtests") removed the "Memory out of range" subtest due to it being
dependent on the memory layout of the test process having an invalid
memory address just after the `*futex_ptr` allocated memory.

Reintroduce this test and make it deterministic, by allocation two
memory pages and marking the second one with PROT_NONE.

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.
