Subject: [PATCH -V8 0/3] numa balancing: Migrate on fault among multiple bound nodes

To make it possible to optimize cross-socket memory accessing with
AutoNUMA even if the memory of the application is bound to multiple
NUMA nodes.

Patch [2/3] and [3/3] are NOT kernel patches.  Instead, they are
patches for man-pages and numactl respectively.  They are sent
together to make it easy to review the newly added kernel API.

Changes:

v8:

- Rebased on latest upstream kernel v5.11-rc2

v7:

- Make set_mempolicy() return -1 with errno is set to EINVAL if mode
  isn't MPOL_BIND per Mel's comments.  Revise document accordingly
  too.

v6:

- Rebased on latest upstream kernel v5.10-rc5

- Added some benchmark data and example in patch description of [1/3]

- Rename AutoNUMA to NUMA Balancing

- Add patches to man-pages [2/3] and numactl [3/3]

v5:

- Remove mbind() support, because it's not clear that it's necessary.

v4:

- Use new flags instead of reuse MPOL_MF_LAZY.

v3:

- Rebased on latest upstream (v5.10-rc3)

- Revised the change log.

v2:

- Rebased on latest upstream (v5.10-rc1)

Best Regards,
Huang, Ying
