[PATCH v6 06/10] mm/memory_hotplug: Poison memmap in remove_pfn_range_from_zone()

Let's poison the pages similar to when adding new memory in sparse_add_section(). Also call remove_pfn_range_from_zone() from memunmap_pages(), so we can poison the memmap from there as well. While at it, calculate the pfn in memunmap_pages() only once. Cc: Andrew Morton Cc: David Hildenbrand C
