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.
