Subject: [GIT PULL] Kbuild fixes for 6.18 #1

Hi Linus,

Please pull the initial round of fixes for Kbuild for 6.18. Everything
but the final change has been in -next for a couple of cycles but I
wanted to record some last minute tags so it is recently rebased.

If there are any issues, please let me know.

Cheers,
Nathan
