Highlights for this merge window:
* The whole caching of module code into huge pages by Mike Rapoport is going
in through Andrew Morton's tree due to some other code dependencies. That's
really the biggest highlight for Linux kernel modules in this release. With
it we share huge pages for modules, starting off with x86. Expect to see that
soon through Andrew!
* Helge Deller addressed some lingering low hanging fruit alignment
enhancements by. It is worth pointing out that from his old patch series
I dropped his vmlinux.lds.h change at Masahiro's request as he would
prefer this to be specified in asm code [0].

* Matthew Maurer and Sami Tolvanen have been tag teaming to help
get us closer to a modversions for Rust. In this cycle we take in
quite a lot of the refactoring for ELF validation. I expect modversions
for Rust will be merged by v6.14 as that code is mostly ready now.
* Adds a new modules selftests: kallsyms which helps us tests find_symbol()
and the limits of kallsyms on Linux today.
* We have a realtime mailing list to kernel-ci testing for modules now
which relies and combines patchwork, kpd and kdevops:
- https://patchwork.kernel.org/project/linux-modules/list/
- https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/README.md
- https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/kernel-ci-kpd.md
- https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/linux-modules-kdevops-ci.md
If you want to help avoid Linux kernel modules regressions, now its simple,
just add a new Linux modules sefltests under tools/testing/selftests/module/
That is it. All new selftests will be used and leveraged automatically by
the CI.
