Hey Bradley \o
Thanks for your review.

I wrote the comment myself, but LLM helped me with ping-pong reviews,
for example, checking corner cases, commenting on potential ideas. For
example, in a first version I just updated this write_sysreg() to the
CPU id, but then started to think "why am I doing this if the register
is updated at every exit?". "Talking" with the LLM gave me confidence to
suppress this write, due to the reason well explained in the comment heh

Cheers!
