Subject[PATCH v5 0/2] make hugetlb_optimize_vmemmap compatible with memmap_on_memory
Date
This series makes hugetlb_optimize_vmemmap compatible with memmap_on_memory
and is based on mm-stable. The reason refers to the patch 2's commit log.

v5:
- Replace enum to defines per David.
- Walk vmemmap page tables to avoid false-positive.

v4:
- Fix compiling error when CONFIG_MEMORY_HOTPLUG is disabled reported by kernel test robot.
- Fix a bug when memory_block_size_bytes() is not equal to section size.

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
