I'm confused. That wasn't a patch submission, but reporting performance
results for my patch from late 2024? (and thanks for those!)

The patch was also already merged in late 2024:

commit d4148aeab412432bf928f311eca8a2ba52bb05df
Author: Vlastimil Babka <vbabka@suse.cz>
Date:   Thu Oct 24 17:12:29 2024 +0200

    mm, mmap: limit THP alignment of anonymous mappings to PMD-aligned sizes


So there's nothing more to do here AFAIK.
