Rasmus Villemoes b08e50dd64 mm/page_alloc: __alloc_pages_bulk(): do bounds check before accessing array 
In the event that somebody would call this with an already fully
populated page_array, the last loop iteration would do an access beyond
the end of page_array.

It's of course extremely unlikely that would ever be done, but this
triggers my internal static analyzer.  Also, if it really is not
supposed to be invoked this way (i.e., with no NULL entries in
page_array), the nr_populated<nr_pages check could simply be removed
instead.

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.
