[PATCH v2 0/5] mm/memory_hotplug: online_pages() cleanups

[David Hildenbrand <david@redhat.com>]

Some cleanups (+ one fix for a special case) in the context of
online_pages(). Hope I am not missing something obvious. Did a sanity test
with DIMMs only.

v1 -> v2:
- "mm/memory_hotplug: Handle unaligned start and nr_pages in
   online_pages_blocks()"
-- Turned into "mm/memory_hotplug: make sure the pfn is aligned to the
		order when onlining"
-- Dropped the "nr_pages not an order of two" condition for now as
   requested by Michal, but kept a simplified alignment check
- "mm/memory_hotplug: Drop PageReserved() check in online_pages_range()"
-- Split out from "mm/memory_hotplug: Simplify online_pages_range()"
- "mm/memory_hotplug: Simplify online_pages_range()"
-- Modified due to the other changes

David Hildenbrand (5):
  resource: Use PFN_UP / PFN_DOWN in walk_system_ram_range()
  mm/memory_hotplug: Drop PageReserved() check in online_pages_range()
  mm/memory_hotplug: Simplify online_pages_range()
  mm/memory_hotplug: Make sure the pfn is aligned to the order when
    onlining
  mm/memory_hotplug: online_pages cannot be 0 in online_pages()
