This series makes hugetlb_optimize_vmemmap compatible with memmap_on_memory

v3:
- Switch complicated enumeration magic (David).
- Introduce PageVmemmapSelfHosted to make both parameters compatible (David and Oscar).

v2:
- Fix compile error when !CONFIG_ZONE_DEVICE reported by kernel test robot.

Muchun Song (2):
mm: memory_hotplug: enumerate all supported section flags
mm: memory_hotplug: make hugetlb_optimize_vmemmap compatible with
memmap_on_memory
