"relocation to !ENDBR" objtool warnings

Hi Josh and Peter,

I just sent three patches for the most common objtool warnings I get
with gcc-14 on linux-next.

There is one more that I can't figure out, maybe you have an idea
already. I've attached a .config that shows the problem in two files
when built with gcc-14.2.0.
