David Hildenbrand 00ff9a91bd mm/memory_hotplug.c: use PFN_UP / PFN_DOWN in walk_system_ram_range()
Patch series "mm/memory_hotplug: online_pages() cleanups", v2.

Some cleanups (+ one fix for a special case) in the context of
online_pages().

This patch (of 5):

This makes it clearer that we will never call func() with duplicate PFNs
in case we have multiple sub-page memory resources.  All unaligned parts
of PFNs are completely discarded.

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.
