Subject: [PATCH 0/2] support multi-size THP numa balancing

This patchset tries to support mTHP numa balancing, as a simple solution
to start, the NUMA balancing algorithm for mTHP will follow the THP strategy
as the basic support. Please find details in each patch.

Changes from RFC v2:
 - Follow the THP algorithm per Huang, Ying.

Changes from RFC v1:
 - Add some preformance data per Huang, Ying.
 - Allow mTHP scanning per David Hildenbrand.
 - Avoid sharing mapping for numa balancing to avoid false sharing.
 - Add more commit message.

Baolin Wang (2):
  mm: factor out the numa mapping rebuilding into a new helper
  mm: support multi-size THP numa balancing
