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.
