Subject: [PATCH 0/2] memory hotplug follow up fixes

Hi Andrew,
Heiko Carstens has noticed an unexpected memory online behavior for the
default onlining (aka MMOP_ONLINE_KEEP) and also online_kernel to other
kernel zones than ZONE_NORMAL. Both fixes are rather straightforward
so could you add them to the memory hotplug rewrite pile please?

Shortlog
Michal Hocko (2):
      mm, memory_hotplug: fix MMOP_ONLINE_KEEP behavior
      mm, memory_hotplug: do not assume ZONE_NORMAL is default kernel zone
