page-allocator: reset wmark_min and inactive ratio of zone when hotpl…
…ug happens Solve two problems. Whenever memory hotplug sucessfully happens, zone->present_pages have to be changed. 1) Now memory hotplug calls setup_per_zone_wmark_min only when online_pages called, not offline_pages. It breaks balance. 2) If zone->present_pages is changed, we also have to change zone->inactive_ratio. That's because inactive_ratio depends on zone->present_pages.
