If it is at all possible I would REALLY like to get:
x86: Use `3/4*sizeof(per-thread-L3)` as low bound for NT threshold.
- https://patchwork.sourceware.org/project/glibc/patch/20230718152759.219727-1-goldstein.w.n@gmail.com/
and
x86: Fix slight bug in `shared_per_thread` cache size calculation.
- https://patchwork.sourceware.org/project/glibc/patch/20230718041433.217111-1-goldstein.w.n@gmail.com/
in.

They are important follow ups to the memcpy threshold changes. Without them
we may have erratic performance on some x86 platforms (including AMD).
