[PATCH 6.6.y 0/3] mm/damon: porting fixes that cherry-pick failed on 2026-11-07

[SJ Park]

Manually port three DAMON fixes that cherry-pick failed [1-3] and turned
out to really need to be picked.  Note that seven patches [4-10] that
also failed in the same day were having wrong Cc:stable@ tags, so
ignored.
