x86: I will pick this up, but if x86 wants to do so, that would be
welcome -- in which case:

    Acked-by: Miguel Ojeda <ojeda@xxxxxxxxxx>

and I would recommend updating the Cc stable tag to mention 6.13 and
the reason to avoid over-backports, e.g.

    Cc: <stable@xxxxxxxxxxxxxxx> # Needed in 6.12.y and 6.13.y only
(Rust is pinned in older LTSs).

Cheers,
Miguel
