Greetings!!!

I see below build warnings while compiling mainline kernel on IBM Power9 system.

Repo Link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/

Head Commit: f6e0150b2003fb2b9265028a618aa1732b3edc8f

Attached is the .config.

Machine: IBM Power9

gcc version 11.5.0

What is the ld version in your system.

Please find the ld version below.

GNU ld version 2.35.2-59.el9

ah ok that explains. Kindly can you try with this patch and let us know whether 
this fixes the warning in your setup

Reason for asking is that currently with

commit  579aee9fc594a ("powerpc: suppress some linker warnings in recent linker versions")

ld version greater than >2.39, this warning is being suppressed.
