Subject: [PATCH v4 0/2] handle memoryless nodes more appropriately

Hi all,

Currently, in the process of initialization or offline memory, memoryless
nodes will still be built into the fallback list of itself or other nodes.

This is not what we expected, so this patch series removes memoryless
nodes from the fallback list entirely.

This series is based on the next-20231018.

Comments and suggestions are welcome.

Thanks,
Qi

Changlog in v3 -> v4:
 - fix typo in the commit messages and comment (pointed by Ingo Molnar)
 - collect Acked-bys

Changlog in v2 -> v3:
 - add a comment in [PATCH v2 2/2] (suggested by David Hildenbrand)
 - collect Acked-bys

Changlog in v1 -> v2:
 - modify the commit message in [PATCH 1/2], mention that it can also fix the
   specific crash. (suggested by Ingo Molnar)
 - rebase onto the next-20231018
