Hello everyone,

#regzbot introduced v6.7.5..v6.7.6

I'm experiencing an issue where kexec does a full firmware reboot 
instead of kexec reboot.

Issue first submitted at OpenSuse bugzilla [0].

OS details as follows:
Distributor ID:	openSUSE
Description:	openSUSE Tumbleweed-Slowroll
Release:	20240213

Issue has been reproduced by building kernel from source.

kexec works as expected in kernel v6.7.5.
kexec does full firmware reboot in kernel v6.7.6.

I followed the docs here [1] to perform git bisect and find the culprit, 
hope it's alright as I'm quite out of my depth here.

Git bisect logs:
git bisect start
# status: waiting for both good and bad commits
# bad: [b631f5b445dc3379f67ff63a2e4c58f22d4975dc] Linux 6.7.6
git bisect bad b631f5b445dc3379f67ff63a2e4c58f22d4975dc
# status: waiting for good commit(s), bad commit known
# good: [004dcea13dc10acaf1486d9939be4c793834c13c] Linux 6.7.5
git bisect good 004dcea13dc10acaf1486d9939be4c793834c13c

Let me know if there's anything else I can do to help troubleshoot the 
issue.
