Patch series "mm: minor cleanups around NUMA hinting". Working on some GUP cleanups (e.g., getting rid of some FOLL_ flags) and preparing for other GUP changes (getting rid of FOLL_FORCE|FOLL_WRITE for for taking a R/O longterm pin), this is something I can easily send out independently. Get rid of FOLL_NUMA, allow FOLL_FORCE access to PROT_NONE mapped pages in GUP-fast, and fixup some documentation around NUMA hinting. This patch (of 3): No need for a special flag that is not even properly documented to be internal-only. Let's just factor this check out and get rid of this flag. The separate function has the nice benefit that we can centralize comments.

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.
