Ilpo Järvinen ebd40f52de selftests/resctrl: Return NULL if malloc_and_init_memory() did not alloc mem 
[ Upstream commit 22a8be2803 ]

malloc_and_init_memory() in fill_buf isn't checking if memalign()
successfully allocated memory or not before accessing the memory.

Check the return value of memalign() and return NULL if allocating
aligned memory fails.

Fixes: a2561b12fe ("selftests/resctrl: Add built in benchmark")

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 Restructured Text 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.
