Yes, Nathan himself provides those! :)

He may comment further -- I think the Rust compiler itself is not
built (yet?) with PGO etc. like he does for the LLVM side.
As usual -- thanks Nathan!

If you go into the Quick Start guide from your link, you will see it
linked at the top:
https://docs.kernel.org/rust/quick-start.html
I also mentioned these in LPC's Kernel Summit track (sorry, no
video/stream yet, as far as I understand):

I am not sure what you mean -- people has been using Linux with Rust
enabled in real hardware for quite a while, e.g. Android and Asahi,
plus others are upcoming (Fedora, as far as I know), and I regularly
test in CI that the kernel boots in QEMU for several architectures and
configs that we already have in-tree.
I also regularly test in CI that the kernel can be built with
`rustup`'s binaries, with several distro toolchains and with Nathan's
toolchains too.
Cheers,
Miguel
