[RFC PATCH 6.12.y 0/5] mm/damon: porting fixes that cherry-pick failed on 2026-11-07

[SJ Park]

Manually port five DAMON fixes that cherry-pick failed [1-5] and turned
out to really need to be picked.  Note that seven patches [6-12] that
also failed in the same day were having wrong Cc:stable@ tags, so
ignored.

Patches that this series is porting.
