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()
